[0033] The utility model introduces a processing tool suitable for non-uniform outer contour cutting tools. Non-uniform outer contours include involute, elliptical, saddle, etc. In this specific embodiment, the groove pressing tool (such as Figure 2 The following is an introduction taking the processing tooling of the outer contour (shown) as an example.

[0036] The figure shows a base 1, a rotating assembly and a template assembly etc. of a processing tool suitable for non-uniform outer contour tools.

[0042] The outer contour of the mold reference part 4 is consistent with the outer contour of the workpiece 3 to be processed and is an involute.

[0043] When in use, the processing equipment is arranged at one side of the front end of the sliding assembly, and the processing end is attached to the workpiece 3 to be processed. Since the outer contour is an involute, when the rotating assembly drives the mold reference part 4 to rotate, when rotating from the short diameter end of the involute to the long diameter end, the mold reference part 4 is thrusted by the abutment of the abutment 5, and the sliding assembly moves along the slide 2; when rotating from the long diameter end of the involute to the short diameter end, the mold reference part 4 is pulled back due to the tension of the shaping assembly, and is always in contact with the abutment 5, and the workpiece 3 to be processed always moves synchronously with the mold reference part 4. Therefore, the processing end processes the workpiece 3 to be processed and can process a contour line consistent with the mold reference part 4. Further, the shaping assembly is always in a tension state with respect to the sliding assembly.

[0044] It should be noted that, in actual implementation, the processing direction of the processing equipment can be consistent with the elastic direction of the shaping component.

[0050] Specifically, in this embodiment, an intermediate plate 11 is provided between the shaping seat 9 and the base 1, and a plurality of connection holes are provided on the shaping seat 9 and the intermediate plate 11 for screws to penetrate and fix the two together, and a plurality of connection holes are provided on the base 1 for screws to fix the intermediate plate 11 and the base 1 together;

[0055] Specifically, in this embodiment, the workpiece 3 to be processed has a through hole with key teeth inside, and the structure of the corresponding positioning assembly is: an embedded block 12 located below the workpiece 3 to be processed, and a pressure plate 13 located above the workpiece 3 to be processed.

The embedded block 12 is relatively fixedly connected to the backing reference part 4 to achieve synchronous movement of the workpiece 3 to be processed and the backing reference part 4.

[0056] More specifically, the outer contour dimensions of the embedded block 12 and the pressing plate 13 are both smaller than the dimensions of the workpiece 3 to be processed.

[0057] More specifically, a support plate 14 is provided between the profiling reference member 4 and the positioning assembly, and a plurality of connecting holes are provided on the support plate 14 for connecting the embedded block 12, the support plate 14 and the profiling reference member 4 together by screws.

The cover plate 15 has a through hole at its center and a plurality of sixth through holes distributed around the through hole. In this way, the cover plate 15 can be pressed by hand to apply external force to rotate the mold assembly.

[0059] More specifically, in order to make the positioning more convenient and accurate during installation, the positioning assembly also includes a positioning piece, and the bottom surface of the embedded block 12 is provided with a positioning groove matching the positioning piece.

[0060] Furthermore, a fourth through hole is provided at the center of the prototype reference member 4, and a plurality of seventh through holes are provided outside the fourth through hole.

[0061] Furthermore, the rotating assembly includes a rotating member 16 and a bearing 17. The lower part of the rotating member 16 is columnar, penetrates into the first through hole, and is connected to the first through hole through the bearing 17; a plurality of connecting holes are arranged on the top surface of the rotating member 16, and the rotating member 16 and the backing reference member 4 are connected together by screws, and a stepped boss is arranged at the center of the top surface of the rotating member 16 to be embedded in the fourth through hole, so that the rotating member 16 and the backing reference member 4 move synchronously.

[0062] In order to ensure that the rotating assembly does not shake during rotation, at least two bearings 17 are provided in the first through hole for connecting the rotating member 16 to ensure that the center line of the rotating assembly coincides with the center line of the first through hole.

[0063] Specifically, in this embodiment, the workpiece 3 to be processed has an involute profile, and the outer contour of the mold reference part 4 is an involute.

[0064] To be more specific, in this embodiment, the workpiece 3 to be processed is only processed on half of its outer contour, and the outer contour of the backing reference member 4 is also only half of its outer contour as an involute, and a groove is cut inward at the edge position of the backing processing as a non-backing area, so that when in use, it does not need to be rotated a circle, and only the backing area is repeatedly rotated to achieve the processing of the half-side outer contour of the workpiece 3 to be processed. Therefore, in this embodiment, two protrusions (named as reference protrusions 19) are set at the corresponding positions on the bottom surface of the backing reference member 4, and a protrusion (named as a limit protrusion 20) is set on the slider 7. In this embodiment, the protrusions are all nuts, and the limit protrusion 20 is located in the non-backing area, and the top surface of the limit protrusion 20 is higher than the bottom surface of the reference protrusion 19. In this way, when the backing assembly is rotated, one reference protrusion 19 touches the limit protrusion 20, and then the backing assembly is rotated in the opposite direction until the other reference protrusion 19 touches the limit protrusion 20, and the backing assembly is rotated in the opposite direction again, and the cycle is repeated until the workpiece 3 to be processed is completed.
