1. Technical Field
The present application relates to a cutting arrangement for cutting a workpiece having a tool holder which holds a plurality of cutting tools therein. The present application further relates to a tool holder for accommodating cutting tools.
2. Background Information
Background information is for informational purposes only and does not necessarily admit that subsequently mentioned information and publications are prior art.
During the machining of workpieces, tool holders, among other things, into which cutting tools are interchangeably inserted are used. In this case, the cutting tools have a fastening shank with which they can be inserted into a tool receptacle of the tool holder and clamped therein. The cutting tool has in this case a blade or a cutting element which can be interchangeably fastened to the cutting tool.
In order to keep the downtimes during a tool change as short as possible, problem-free and simple interchangeability of the cutting tool is important.
Some quick-change tooling systems include a cutting tool which can be interchangeably fastened in a tool holder designated as a tool carrier part. In this case, the cutting tool is inserted into a tool receptacle. A bore, into which a clamping bolt is inserted, passes through the tool holder transversely to the longitudinal direction of the tool receptacle. Said clamping bolt is screwed with its one end into a clamping nut. The clamping nut is in this case inserted into the bore from the opposite side. The clamping bolt and the clamping nut are essentially freely movable inside the bore. During the clamping, a bolt head of the clamping bolt and the clamping nut are drawn toward one another and thereby hold the fastening shank of the cutting tool in the tool receptacle.
A further measure in order to reduce the downtime comprises providing a plurality of tool receptacles on a tool holder. During the workpiece machining, it is therefore possible, for example by rotating the tool holder, to bring different types of cutting tools for different machining operations into a machining position. A worn cutting tool can also be rotated out of the machining position and an unused cutting tool can be rotated into the machining position. In such a multiple tool holder, however, there is the problem that the tool holder inevitably increases in volume. This increased space requirement may lead to disadvantages in restricted space conditions.
An object of the present application is to disclose a compact tool holder which is designed for accommodating a plurality of cutting tools and makes possible quick and simple exchange of the respective cutting tool.
This object is achieved according to the present application by a tool holder having a number of tool receptacles which are provided in a parent body and into which a respective cutting tool can be inserted with a fastening shank and can be clamped in the tool receptacle via a clamping device. The clamping device in this case comprises a clamping bolt which extends laterally through a bore in the parent body up to the tool receptacle and has at its outer end a bolt head which can be actuated via a setting tool. The bolt head is in this case locked by a locking element which is attached to the parent body in the region of the bore and which forms a stop for the bolt head.
In one possible embodiment of the present application, the clamping bolt is locked by the additional locking element to prevent, restrict, and/or minimize it from falling out and that therefore the clamping device can be inserted into the parent body merely from one side. On the whole, therefore, a captive locking means is formed by the locking element. A through-bore and accessibility of the bore on both sides is therefore not necessary or may not be desired and is also not provided. Due to this configuration, therefore, the tool receptacles can be integrated in the parent body without any problems, such that they are arranged next to one another in said parent body. It is therefore not necessary or may not be desired for the tool receptacles to be detachably connected to the parent body as separate elements. For this leads to an increased space requirement on account of the requisite or desired additional fastening elements.
In contrast, in the tool holder described here, the parent body is in one possible embodiment of one piece design, i.e. the tool receptacles are designed as bores in a uniform block forming the parent body. In principle, it is possible to provide a plurality of tool carrying elements, each of the individual tool carrying elements in one possible embodiment having a tool receptacle which is provided with the clamping device. In this embodiment variant, the individual tool carrying elements form, if need be or if desired together with a supporting body for the individual tool carrying elements, the parent body of the tool holder.
One possible embodiment of the present application, a compact configuration is achieved in a tool holder having two or more tool receptacles. In principle, merely a single tool receptacle may also be provided.
The tool holders are in one possible embodiment arranged at the end face or radially at the circumferential side.
The cutting tool comprises, for example, a blade carrier, such as, for example, a cassette, to which a cutting element, for example, an indexable insert, is interchangeably fastened. The cutting tool therefore has at its rear end the clamping or fastening shank with which it can be inserted into the tool receptacle. The cutting element or a blade is provided at the opposite end. The cutting tool may in principle also be monolithic, i.e. the blade is not interchangeably fastened to the cutting tool but rather is an integral and fixedly connected component of the cutting tool.
According to one possible embodiment, the locking element is in this case designed as an insert. The locking element is therefore a separate component which is simple to produce and in addition can also be connected to the parent body in a simple and easy-to-fit manner.
Provision is in one possible embodiment made here for the locking element to be detachably fastened to the parent body. This permits problem-free and simple exchange of the clamping bolt, provided this becomes necessary and/or desired. For example, a clamping connection or a form-fitting connection, for example like a bayonet catch, is provided for the detachable fastening. The locking element is in one possible embodiment screwed to the parent body.
In addition, according to one possible embodiment, provision is made for the locking element to form a guide for the bolt head. That is to say, at least a section of the bolt head slides in the bolt longitudinal direction inside the locking element. Exact or generally positioning of the clamping bolt and thus a clamping effect of the entire clamping device that is defined as precisely as possible or generally are achieved by this guide.
In one possible embodiment, provided on the bolt head is a counter-stop, in one possible embodiment in the form of an annular web, which in the fitted position is opposite the stop provided on the locking element. The interaction of the stop with the counter-stop prevents, restricts, and/or minimizes the clamping bolt from falling out of the bore, for example if no cutting tool is arranged in the tool receptacle and the clamping bolt therefore rests loosely in the bore without an abutment. The configuration in one possible embodiment of an annular web following the bolt head can be implemented without any problems from the production point of view. As an alternative to the arrangement of the annular web on the clamping bolt, provision is made for the bolt head itself to form the counter-stop, i.e. for it to interact by means of its end face with the stop of the locking element. In this embodiment variant too, the locking element in one possible embodiment forms a guide for the bolt head.
In at least one possible embodiment of the present application, the locking element is a sleeve, in one possible embodiment a threaded sleeve, which can be detachably inserted or screwed into the bore from outside. In this case, the inner lateral surface of the in one possible embodiment cylindrical sleeve forms a guide surface for the cylindrical lateral surface of the bolt head in a simple manner. At the same time, the sleeve is in one possible embodiment simple to produce.
As an alternative thereto, the locking element is designed as an in on possible embodiment plate-shaped element, in one possible embodiment a perforated plate, which is fastened to the parent body. This plate is detachably fastened to the parent body, for example via screws.
According to one possible embodiment, the locking element does not protrude beyond the parent body, i.e. the locking element is flush with the outer side of the parent body or is arranged further on the inside within the bore in the parent body. The compact construction of the entire tool holder is thereby obtained.
With regard to the clamping functionality for clamping the cutting tool, a clamping nut is provided which is displaceable in the bore longitudinal direction and into which the clamping bolt can be screwed with its one end. At their regions facing one another, the clamping nut and the clamping head of the clamping bolt have in one possible embodiment tapered sections which act as clamping surfaces. When the clamping bolt is screwed into the clamping nut, these two tapered clamping surfaces, designed like frustums of a cone, are moved toward one another and thereby reliably hold the fastening shank, located between them, of the cutting tool in the tool receptacle.
In this case, the freedom of movement of the clamping nut in the bore longitudinal direction is in one possible embodiment restricted, such that the clamping nut is displaceable within a defined range. Provided for this purpose is in one possible embodiment a clamping pin which runs laterally through the parent body in the direction of the clamping nut.
The locking pin in this case in one possible embodiment forms a form fit. In one possible embodiment, the locking pin engages in a groove-like recess of the clamping nut. The width of the groove is in this case greater than the diameter of the locking pin, such that a relative movement is thus made possible between the groove and the locking pin. This relative movement determines in this case the free space within which the clamping nut can move in the bore longitudinal direction.
The above-discussed embodiments of the present invention will be described further herein below. When the word “invention” or “embodiment of the invention” is used in this specification, the word “invention” or “embodiment of the invention” includes “inventions” or “embodiments of the invention”, that is the plural of “invention” or “embodiment of the invention”. By stating “invention” or “embodiment of the invention”, the Applicant does not in any way admit that the present application does not include more than one patentably and non-obviously distinct invention, and maintains that this application may include more than one patentably and non-obviously distinct invention. The Applicant hereby asserts that the disclosure of this application may include more than one invention, and, in the event that there is more than one invention, that these inventions may be patentable and non-obvious one with respect to the other.
One possible embodiment of the present application is explained in more detail below with reference to the drawings, in which, in each case in schematic and partly simplified illustrations:
Parts having the same effect are in each case provided with the same designations in the figures.
The tool holder 2 shown in
The tool holder 2 comprises a parent body 6 which is of one-piece monolithic design or alternatively has a plurality of tool carrying elements bearing against one another. In this case, each tool carrying element carries a respective tool receptacle 4. At its rear end, the parent body 6 has a shank 8 with which it is clamped in place in a corresponding receptacle of a machine tool. The tool holder 2 therefore extends from its front end face, in which the tool receptacles 4 are incorporated like bores, in the longitudinal direction 10 to the shank 8.
The machining of a workpiece is normally effected by means of one of the respective inserted cutting tools. In the process, the workpiece to be machined normally rotates and the cutting tool is arranged in a fixed position or performs possibly a linear movement along a predetermined path. On the whole, therefore, a turning tool is formed in which the machining is effected on the basis of a relative rotary movement between workpiece and cutting tool. The multiple tool holder 2 serves in one possible embodiment for the multi-stage machining of the workpiece by different cutting tools. To change the respective cutting tool in engagement with the workpiece, it is merely necessary and/or desired to rotate the tool holder 2, for example, by about ninety degrees.
At its front end face, a respective coolant outlet 12 is arranged relative to each tool receptacle 4, via which coolant outlet 12 coolant is fed to the cutting tool when required and/or desired during the machining. The parent body 6 has an essentially polygonal cross-sectional area, octagonal in one possible embodiment, and is of rotationally symmetrical design about ninety with respect to the longitudinal axis 10.
Starting from its lateral surface, respective bores 14 oriented approximately perpendicularly or virtually perpendicularly to the direction defined by the longitudinal axis 10 are incorporated relative to the individual tool receptacles 4. The bores 14 in this case each end inside the parent body 6 and thus do not form through-bores. The elements of the clamping device, namely a clamping nut 16, a clamping bolt 18 and a threaded sleeve 20 forming a locking element are inserted into each of the bores 14 from outside. For fitting, a section of the clamping bolt 18 is already normally screwed with an end bolt thread 22 into the clamping nut 16. Of especial importance is the fact that the elements of the clamping device can be inserted on one side, i.e. from a single outer side. It is therefore not necessary or may not be desired for there also to be accessibility of the tool receptacle 4 from the opposite side.
Rotationally offset by approximately ninety degrees from the bore 14, a locking pin 26 is inserted through a further bore 24 likewise from the lateral surface side of the parent body 6. Said locking pin 26 extends right into the tool receptacle 4 and interacts with the clamping nut 16 in the fitted state. In this case, the locking pin 26 limits the displaceability of the clamping nut 16 in the longitudinal direction 28 of the bore 14. The locking pin 16 is held in the parent body 6 via a headless set screw 30.
The clamping bolt 18 has a cylindrical bolt head 32. In one possible embodiment, the cylindrical bolt head 32 has an internal polygonal receptacle 34 which serves to accommodate a setting tool, via which the clamping bolt 18 can be turned. In the bore longitudinal direction 28 in the direction toward the clamping nut 16, an annular web 36 which defines a counter-stop adjoins the cylindrical lateral surface of the bolt head 32. Said annular web is followed further by a tapered, frustoconical clamping surface 38A. Corresponding thereto, the clamping nut 16 also has such a clamping surface 38B.
In the fitted state, the threaded sleeve 20 is screwed into the bore 14 in the parent body 6, the bore 14 having a corresponding internal thread for this purpose. In the final fitted state, the threaded sleeve 20 lies completely inside the parent body 6 and therefore does not protrude. The threaded sleeve 20 is of slotted design on its outer annular side, such that it can be screwed into or out of the bore 14 via a conventional screwdriver.
With its internal diameter, the inner side of the threaded sleeve 20 is adapted to the external diameter of the bolt head 32 in the region of its outer lateral surface. That is to say, the threaded sleeve 20 accommodates the bolt head 32 at most up to the annular web 36. In the process, a slight clearance is formed between the sleeve inner side and the lateral surface of the bolt head 32. The sleeve inner side therefore constitutes a guide 40 for the bolt head 32. The front annular surface, oriented toward the bolt head 32, of the threaded sleeve 20 constitutes a stop 42, with which the annular web 36 interacts as counter-stop. The stop 42 and the annular web 36 form, in their interaction, a captive locking means for the clamping bolt 18 and the clamping nut 16.
The threaded sleeve 20 therefore serves different purposes. First, the threaded sleeve 20, via the stop 42, virtually ensures that the clamping bolt or clamping screw 18 cannot become dislodged or inadvertently removed out of the tool holder body 6 through the bore 14. Second, the threaded sleeve 20 acts as a guide to position the clamping bolt 18 in a desired position in the bore 14. Third, the threaded sleeve 20 retains the clamping bolt 18 in position such that the clamping bolt 18 does not move substantially in a direction perpendicular to the longitudinal direction or axis 28 of the clamping bolt 18, such as during a cutting or machining operation. Such movement of the clamping bolt 18 would be undesirable as the movement could possibly permit movement of the cutting device secured by the clamping bolt 18, especially during a cutting operation, which would lead to imprecise or incorrect cutting of a workpiece.
In other words and in accordance with at least one possible embodiment with the present application, the fitted state of the clamping device may occur when the elements of the clamping device are inserted into the parent body 6 of the tool holder 2 and screwed into engagement with the tool holder 2. For example, the clamping device is in a fitted state when the locking pin 26 interacts with the clamping nut 16 and also when the end bolt thread 22 is fully engaged with the clamping nut 16 and the stop 42 of the threaded sleeve 20 and the annular web 36 of the clamping bolt 18 form a captive locking means.
As can be seen in one possible embodiment from
During use of the tool holder 2, the elements of the clamping device, namely the clamping nut 16, the clamping bolt 18, and the threaded sleeve 20 on the one hand and furthermore the locking pin 26 and the headless set screw 30 on the other hand, are already arranged prefitted in the tool holder 2. To insert the cutting tool, said cutting tool, with its suitably provided fastening shank in front, is inserted into the tool receptacle 4. The clamping bolt 18 is screwed further into the clamping nut 16 by tightening said clamping bolt 18, such that the two gripping surfaces 38A, 38B are moved toward one another and the fastening shank is held in both a gripping and form-fitting manner.
For the tool change, the clamping bolt 18 needs to be or should be slackened, such that the gripping surfaces 38A, 38B are moved away from one another in the opposite direction. In the process, the clamping bolt 18 can be unscrewed until it comes to bear with its annular web 36 against the stop 42 of the threaded sleeve 20. In this released position, too, a section of the bolt thread 22 remains in the clamping nut 16. The configuration of the fastening shank and of the basic clamping mechanism can be seen in particular from DE 600 23 191 T2 and its corresponding U.S. Pat. No. 6,415,696 B1. FIGS. 1, 2, and 4 of U.S. Pat. No. 6,415,696 B1 and their following corresponding descriptions have been included in the present application as
The toolholder 25 may have a support portion 226 with a pocket 27 for receiving a cutting insert (not shown) therein. However, the toolholder 25 is presented for illustrative purposes and, as will be discussed, the shank 230 of the present application may be used with any of a variety of configurations attached to the shank. Therefore, the term “toolholder” used herein should encompass any configurations secured to the tool support member 15 through the shank 230.
The tool support member 15 has a forwardly facing surface 35 and a bore 240 along a longitudinal axis L. The surface 35 may be mateable with an opposing rearward abutment surface 45 on the toolholder 25 and these surfaces may be, among other shapes, conical or planar, to matingly contact one another. The bore 240 extends rearwardly from the forwardly facing surface 35 for receiving the tubular toolholder shank 230 of the toolholder 25.
The actuating bolt 220 is positioned in the tool support member 15 along a radial axis R1, which is radial to the longitudinal axis L, for locking the toolholder 25 into the tool support member 15 or for ejecting the toolholder 25 from the tool support member 15. The actuating bolt 220 is positioned within a passageway 50 extending through the tool support member 15 along axis R1, thereby defining a first aperture 55 and a second aperture 60 within the tool support member 15 wherein the second aperture 60 is directly opposed or generally opposed to the first aperture 55.
As further illustrated in
The shank 230, comprises a first toolholder lockable surface 90. To promote the removal of the toolholder 15 from the tool support member 15, the toolholder shank 230 has a flat surface 33 on the top of the shank 230.
Since the bolt 220 and the nut 75 are free to slide in the apertures 55, 60 when the toolholder 25 is not inserted in the tool support member 15 then, as a practical matter, the bolt 220 should be prevented, restricted, or minimized from sliding out from the tool support member 15. As illustrated in
To advance the actuating nut 75 upon the actuating bolt 220 it is necessary or may be desired when the actuating bolt 220 is rotated to rotationally restrain, restrict, or minimize the actuating nut 75. In accordance with at least one possible embodiment, as illustrated in
In
For convenience, reference will be made to a forward half 160 and a rearward half 165 of the actuating bolt 220, as illustrated in
All of the forces or substantially all of the forces or most of the forces imposed by the actuating bolt 220 and the actuating nut 75 upon the shank 230 during the locking operation are applied rearwardly of radial axis R1. At the forward half 160 of the actuating bolt 220, there is a clearance C1 between the locking surface 70 of the actuating bolt 220 and the perforation 150 and, furthermore, there is a clearance C2 between the locking surface 85 of the actuating nut 75 and the perforation 155. In this manner, the forces opposed by the actuating bolt 220 and the actuating nut 75 in the locked position urge the shank 230 toward the rearward half 165 of the actuating bolt 220.
It should be noted in
To promote the removal of the toolholder 15 from the tool support member 15, the toolholder shank 230, as illustrated in
It is not uncommon for the shank 230 of the toolholder 25 to remain frictionally engaged within the tool support member 15 even after the positive locking provided by the actuating bolt 220 and actuating nut 75 has been relieved. Under such circumstances, it is necessary or may be desired to positively displace the toolholder 25 toward the forward half 160 of the actuating bolt 220 to release the toolholder 25 from the tool support member 15.
As illustrated in
Directing attention to
On the whole, an extremely compact tool holder 2 which has a plurality of tool receptacles 4 for accommodating cutting tools is made possible by the configuration described here. The compact configuration is in this case essentially achieved by virtue of the fact that the tool receptacles 4 are integrated directly in the parent body 6 and do not form mounted separate units. This is substantially achieved by virtue of the fact that the elements of the clamping device are in each case inserted from one outer side of the lateral surface of the parent body 6. Therefore no through-bores need to be provided here. In order to achieve this, the threaded sleeve 20 is designed as a captive locking means for the clamping bolt 18 and the clamping nut 16.
To make it possible for a tool holder 2 that has a number of tool receptacles 4 provided in a base body 6 to be structured in a compact manner, it is provided that a tensioning bolt 18 is led laterally through a bore 14 in the base body 6 to the tool receptacle 4. The tensioning bolt 18 has at its outer end a bolt head 32 which can be actuated by means of a setting tool and is secured by a securing element 20 which is attached to the base body 6 in the region of the bore 14 and forms a stop 42 for the bolt head 32. This configuration allows the entire tensioning device to be mounted in a space-saving way from just one side. The securing element 20 achieves the effect of preventing the elements of the tensioning device from being lost.
