Description
BACKGROUND OF THE INVENTION
Technical Field

The present invention relates generally to a processing tool and a processing tool assembly, and more particularly to a processing tool and a processing tool assembly, wherein the processing tool of the processing tool assembly could be changed easily; multiple workpieces could be processed simultaneously by the processing tool assembly; the processing tool assembly could precisely perform processing.


Description of Related Art

In industrial manufacture, metal processing is applied to manufacture hand tools, transmission components, or precision components. Metal processing primarily utilizes a machine tool to perform processing steps. The machine tool is widely used in the industry, wherein an operation of the machine tool is clamping a workpiece to fix the workpiece on a fixing frame of the machine tool and making the workpiece move relative to the processing tool. By doing this, a surface or a middle portion of the workpiece could be cut, polished, ground, or treated with other motions. So far, the processing could be performed by the machine tool includes facing, centering, drilling holes, boring, reaming, knurling, thread cutting, taper pin cutting, and so on.


Taking the wrench processing as an example, a processing method performed by a conventional broaching machine is described below. FIG. 1 is a top view of a conventional external broach 10 and a fixing seat 15 for processing a wrench W, wherein align a mouth C of the wrench W to a cutting portion 11 of the external broach 10. Generally, the external broach 10 is fixed to fixing seat 15 by inserting an engaged portion 12 of the external broach 10 from an end of the long groove 151 and through a long groove 151 of the fixing seat 15 and then screwing the external broach 10. Then, operate the broaching machine tool to cut the mouth C of the wrench W.


Since the conventional external broach 10 should be disengaged from the end of the long groove 151 of the fixing seat 15, the disengagement of the conventional external broach 10 is restricted, unless a sufficient operating space (which means a length of the external broach 10 plus a length of the fixing seat 15) is provided. Therefore, the maintenance of the broaching machine or replacement of the external broach 10 is inconvenient in a limited operating space, so that the conventional external broach 10 and the fixing seat 15 have room for improvement.


Additionally, when the external broach 10 is fixed to the fixing seat 15, an axial surface 13 of the conventional external broach 10 is perpendicular to a top surface 152 of the fixing seat 15, as shown in FIG. 1. However, when the mouth C of an uncut wrench W aligned corresponding to the cutting portion 11 of the external broach 10 and the size of the uncut wrench W is long, a depth of a place platform of the conventional broaching machine needs to be increased, leading a volume of the broaching machine is increased. Besides, since the axial surface 13 of the conventional external broach 10 is perpendicular to the top surface 152 of the fixing seat 15, the wrench W will shake relative to an assembly of the external broach 10 and the fixing seat 15 during a cutting process, leading producing a defective product (namely, reducing a yield of production).


Besides, the broaching machine with the conventional external broach 10 and the fixing seat 15 could only cut one piece of wrench W once. It is unable to cut multiple pieces of wrenches W at the same time, so that the efficiency of the broaching machine is low.


To sum up, the conventional external broach 10 and the assembly of the fixing seat 15 and the external broach 10 have room for improvement

As illustrated in FIG. 8, the second clamping block set 36 includes a first block 361, a second block 364, and a fastener 367, wherein the first block 361 has an abutting surface 362 and a first incline 363, and the second block 364 has a perforation 365 and a second incline 366. The abutting surface 362 of the first block 361 abuts against the at least one clamped portion 22 of the at least one processing tool 20. The second block 364 touches a second side 325 of the at least one long groove 322. The first incline 363 of the first block 361 contacts with the second incline 366 of the second block 364. The fastener 367 passes through the perforation 365 of the second block 364 and is screwed into the inclined bottom 323 of the at least one long groove 322.


When the fastener 367 is screwed toward the inclined bottom 323 of the at least one long groove 322 to drive the second block 364 to get close to the inclined bottom 323, the second incline 366 of the second block 364 urges against the first incline 363 of the first block 361 to make the first block 361 move in a direction toward the first clamping block set 34, so that the first clamping block set 34 and the first block 361 of the second clamping block set 36 jointly clamp the at least one clamped portion 22 of the at least one processing tool 20.

When the fastener 367 is loosened in a direction away from the inclined bottom 323 of the at least one long groove 322, the elastic member 368 urges the second block 364 to move away from the inclined bottom 323. At this time, the second incline 366 of the second block 364 stops urging the first incline 363 of the first block 361, so that the first block 361 could be manipulated to freely move relative to the second block 364.


As illustrated in FIG. 9, each of the blocking sets 38 includes an urging end 381 which is complementary to one of the abutted ends 214 of the at least one processing tool 20. Each of the abutted ends 214 of the at least one processing tool 20 is the abutted incline 216, and the urging ends 381 of each of the blocking set 38 respectively include an urging incline 382, wherein the abutted incline 216 contacts with the urging incline 382. In the current embodiment, a top portion 383 of the urging end 381 protrudes over the bottom portion 384 of the urging end 381 in the longitudinal direction LD.


The substrate 32 has two blocking walls 326 which is respectively located at each of two ends of the at least one long groove 322, wherein each of the blocking walls 326 has a screw hole 327. Each of the blocking sets 38 includes a blocking member 385 and a screw rod 386, wherein the blocking member 385 includes the urging end 381 adapted to urge the abutted ends 214 of the at least one processing tool 20.

On contrary, when the screw rod 386 is screwed in a direction away from the at least one long groove 322, the screw rod 386 stops urging against the blocking member 385, so that the blocking member 385 could move away from the at least one processing tool 20 to make the urging end 381 of the blocking set 38 not urge against the abutted end 214 of the at least one processing tool 20.


The blocking member 385 has a slot 387, wherein a longitudinal direction of the slot 387 is parallel to the longitudinal direction LD. The inclined bottom 323 of the at least one long groove 322 has a plurality of threaded hole 328. A fastener 388 passes through the slot 387 and is screwed into one of the plurality of threaded holes 328, so that the blocking member 385 is restricted by the fastener 388 to be operated to move along the longitudinal direction LD within a length between two ends of the slot 387.


Additionally, as illustrated in FIG. 9, the processing tool assembly 30 includes at least one intermediate block 39 fixed on the inclined bottom 323 of the at least one long groove 322. When an amount of the at least one processing tool 20 is plural, the at least one intermediate block 39 is clamped between two of the processing tools 20. Each of the abutted ends 214 of the at least one processing tool 20 is an abutted incline 216. Two sides of the at least one intermediate block 39 along the longitudinal direction LD respectively include an abutted incline 216, wherein the abutted incline 216 and the urging incline 391 are abutted to each other. In the current embodiment, top portions 392 of the two sides of the at least one intermediate block 39 protrude over bottom portions 393 of the two sides of the at least one intermediate block 39 in the longitudinal direction LD. In an embodiment, the processing tools 20 could be tools with the same specs or different specs, so that the single processing tool assembly 30 can perform mass production or a variety of processes, thereby enhancing the efficiency of the process.


As illustrated in FIG. 10, the substrate 32 includes two long grooves 322, and the plurality of processing tools 20 could be respectively disposed in the two long grooves 322, so that it is possible to simultaneously cut a mouth C for each of two wrenches W in a single operation of a broaching machine. In practice, the substrate 32 could include three or more long grooves 322 for mounting more processing tools 20, so that a amount of cutting processed wrench W produced in each operation could be increased. Namely, the efficiency of the cutting process of the wrench is enhanced.


With the processing tool and the processing tool assembly provided in the present invention, the processing tools could be changed easily, thereby reducing operating time and saving space that are needed for changing the processing tool. Additionally, the inclining design of the processing tool and the processing tool assembly allows the workpiece to be placed inclinedly, so that additional depth does not need to be adopted to a placing platform to receive a workpiece with longer or greater size to complete a process of the workpiece with longer or greater size, thereby effectively reducing the volume of the broaching machine.
