[0017] Figure 3 This is a top view of an embodiment of the present invention. Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. The embodiments of this utility model are described below with reference to the accompanying drawings.

[0019] like Figure 1-3 As shown, a cam plate precision milling contour fixture includes a base 1 for mounting on a processing equipment. The base 1 is provided with a support assembly for supporting the cam plate 6 to be processed and a fastening assembly for fastening the cam plate 6 to be processed. The fastening assembly includes a base plate 5 fixedly mounted on the base 1. The base plate 5 is provided with a fastening threaded rod 8 that passes through the cam plate 6 to be processed from bottom to top. The cam plate 6 to be processed is provided with a through hole through which the fastening threaded rod 8 can pass. A fastener 7 and a fastening nut 9 for pressing the fastener 7 are sleeved on the fastening threaded rod 8. The fastening assembly is used to fasten the cam plate 6 to be processed.

[0020] The support assembly includes at least three support screws 2, and the base 1 is provided with threaded holes that mate with the support screws 2. The support assembly is used to support the cam plate 6 to be processed. Multiple support screws 2 are provided, and the height of the support screws 2 can be adjusted to meet the support requirements of the uneven bottom of the cam plate 6 to be processed.

[0021] There are four support screws 2, which are arranged in a square and located at the four corners of the square to ensure more reliable support.

[0022] Each support screw 2 is fitted with a support fastening nut 3. The support screw 2 is engaged with the threaded hole on the base 1 to adjust the height. After adjustment, the support fastening nut 3 needs to be tightened. After tightening, the support fastening nut 3 fits against the upper surface of the base 1.

[0023] The base 1 is provided with several connecting holes 4 for mounting the fixture. The specific number of connecting holes 4 can be four, which facilitates the stable and reliable mounting of the fixture on the processing equipment.

[0024] The fastener 7 includes three clamping claws 11, which are evenly arranged along the circumference, and the included angle between any two adjacent clamping claws 11 is equal.

[0025] Each clamping claw 11 has a clamping block 10 at its bottom. The clamping block 10 is detachably connected to the clamping claw 11. By setting the clamping block 10, the clamping claw 11 can better contact the cam plate 6 to be processed, so that the fastener 7 can more stably clamp and fasten the cam plate 6 to be processed.

[0026] During installation, first screw the support screws 2 into the corresponding threaded holes of the base 1. There can be three or four support screws 2 to support the cam plate 6 to be processed. After screwing in the support screws 2, place the cam plate 6 to be processed on them. Adjust the height of each support screw 2 according to the processing requirements. After the height adjustment is completed, tighten the support fastening nut 3. Then adjust the position of the fastener 7. After adjusting the fastener 7 to the appropriate position, tighten the fastening nut 9 to complete the clamping of the cam plate 6 to be processed. Finally, fix the fixture on the processing equipment through the connecting hole 4 to process the cam plate 6.

[0027] By setting the base 1, the entire fixture can be installed on the processing equipment, such as on a machining center, so that the cam plate 6 to be processed can be processed.

[0028] By setting up fastening components, the cam piece 6 to be processed can be fastened to the fixture, improving clamping efficiency and solving the problem of fastening the cam piece 6 during processing;

[0029] By setting up a support component, the cam plate 6 to be processed can be supported, making it easy for the cam plate 6 to be processed to be fastened on the fixture.
