1. Field of the Invention
The present invention relates to an automatic machining machine, and more particularly to a multi-spindle machining machine which can lower size and production cost.
2. Description of the Prior Art
Conventional lateral driving device of a machining machine is disposed on one side of a working room, and a vertical driving device is fixed on the lateral device so that a working head move along X axis by using the working head and along Y axis by using the vertical driving device. However, such a machining machine has a large size to increase production cost.
Another conventional lateral device of a machining machine is fixed on a lower side of a working room, and a vertical driving device is mounted on an upper or lower sides so that the lateral driving device carries a workpiece on a carrier to move along X and Y axes, and the vertical driving device drives the carrier or a working head to move along a Z axis. However, such a machining machine is in a large size to increase production cost.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
The primary object of the present invention is to provide a multi-spindle machining machine which can lower size and production cost.
A multi-spindle machining machine in accordance with a preferred embodiment of the present invention comprises:
a base including a working room to move and rotate a tool and a workpiece;
a working head including a driving spindle to rotably disposed on a lower end thereof, and the lower end of the driving spindle clamping the tool;
a carrier including a seat, a rotary shaft, and a fixing holder, the seat being fixed on one side of the working room, the rotary shaft mounted on the seat laterally and allowing to drive the seat to rotate in an axial direction (A axis), the fixing holder connected to an end portion of the rotary shaft so that the workpiece is fixed to the fixing holder;
a lateral driving device disposed on the base and located on one side of the working room in a horizontal direction to drive the working head to move in an X axis and a Y axis at the working room;
a vertical driving device disposed on the base and located on another side of the working room in a lateral direction to drive the seat to move in Z axis direction.
The present invention will be clearer from the following description when viewed together with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment in accordance with the present invention.
Referring to
the base 1 includes a working room 10 to move and rotate a tool 11 and a workpiece 12, the tool 11 is a milling cutter, a drill, and a grinding cutter, etc.
The working head 2 includes a driving spindle 20 to rotably disposed on a lower end thereof, and the lower end of the driving spindle 20 clamps the tool 11 to have a cutting, drilling, and grinding process.
The carrier 3 includes a seat 30, a rotary shaft 31, and a fixing holder 32. The seat 30 is fixed on one side of the working room 10. The rotary shaft 31 is mounted on the seat 30 laterally and allows to drive the seat 30 to rotate in an axial direction (A axis) by using a pneumatic cylinder or servo motor. The fixing holder 32 includes a lateral shank 33 and two positioning rods 34, the lateral shank 33 is connected to the rotary shaft 31, and the two positioning rods 34 vertically extend from two ends of the lateral shank 33 to fix the workpiece 12 thereon, and upper and lower opposite sides of the workpiece 12 are located between the two positioning rods 34. The fixing holder 32 is designed to include different structures based on the workpiece 12. For example, the fixing holder 32 is designed to include an annular fixing casing to match with a circular workpiece 12, and the fixing holder 32 is designed to include a fixing paw or sleeve to engage or insert a cylinder workpiece 12.
The lateral driving device 4 is disposed on the base 1 and located on one side of the working room 10 in a horizontal direction to drive the working head 2 to move in an X axis and a Y axis at the working room 10.
The vertical driving device 5 is disposed on the base 1 and located on another side of the working room 10 in a lateral direction to drive the seat 30 to move in Z axis direction.
The lateral and vertical driving devices 4, 5 are located on two lateral sides of the working room 10, such as back and right sides of the working room 10 as shown in
Therefore, the multi-spindle machining machine of the present invention includes the following advantages:
1. Lowering size, wherein the vertical driving device 5 drives the carrier 3 to move vertically, and the lateral driving device 4 only allows to drive a small size of working head 2 so as to move frontward and backward, leftward and rightward to work the workpiece 12, such that a largest moving travel of the working head 2 is designed to have a predetermined area matching with the size of the workpiece 12, decreasing size of the multi-spindle machining machine. Besides, the carrier 3 is designed to have a predetermined height to match with a working depth of the workpiece 12, therefore a vertical moving distance is equal to a thickness of the workpiece 12, and the carrier 3 can rotate the workpiece 12, such that the size of the multi-spindle machining machine is saved. Also, the lateral and the vertical driving devices 4, 5 are disposed in a lateral direction of the working room 10 to decrease height of the multi-spindle machining machine.
2. Decreasing production cost, wherein the vertical driving device 5 is fixed on a lateral position outside the lateral driving device 4 so as to assemble the multi-spindle machining machine easily and simplify structure.
3. Facilitating double-side working of the workpiece, wherein the rotary shaft 31 of the carrier 3 rotates to actuate the workpiece 21 on the fixing holder 32 to rotate so as to facilitate the three-dimensional and double-side working of the workpiece 12.
Referring to
As shown in
The vertical driving device 5 includes a third guiding member 50 and a third driver 51, the third guiding member 50 is disposed on the base 1, the seat 30 of the carrier 3 is fixed on the third guiding member 50 to move along a Z axis, and the third driver 51 is disposed on the third guiding member 50 to drive the seat to move.
With reference to
With reference to
the groove 60 is disposed below the working room 10 of the base 1, and is formed in a funnel shape to receive the clips and cutting oil falling from the working room 10. The groove 60 includes a pipe 64 communicating therewith and having a first outlet 65 mounted on a bottom portion of the pipe 64 and having a second outlet 66 fixed on a wall of the pipe 64.
The tank 61 is located below the first outlet 65 to receive the cutting oil falling from the first outlet 65.
The dust collector 62 is coupled to the second outlet 66 by using a connecting tube 67 to draw the chips from the pipe 64.
The switching 63 includes a plate member 68 and a controlling stem 69, the plate member 68 is mounted in the pipe 64 to swing to cover the first outlet 65 and the second outlet 66. The controlling stem 69 is mounted on an outer portion of the pipe 64 to drive the plate member 68 to swing.
