In addition, only one group of holes is made on the indexing plate, and the number of indexing holes is limited. When the number of holes or grooves to be processed on the workpiece is relatively large, the indexing holes on the indexing plate will not be able to line up, and it is impossible to carry out the hole or groove. Groove processing

Embodiment 1
[0023] The fixture of this embodiment is used to process uniformly distributed inclined grooves in the circumferential direction of disk workpieces. Its structure is as follows: figure 1 , attached figure 2 , attached image 3 And attached Figure 4 As shown, it includes a support frame 1, an indexing plate 9 and an installation assembly for fixing the disc workpiece 8 to be processed on the indexing plate 9, and the indexing plate is installed on the indexing plate through an indexing mechanism and a locking and fixing mechanism. On the mounting surface of the support frame, the support frame is a plate-frame support frame, which is designed with a mounting surface for installing the indexing plate and a mounting surface for installing the support frame on the adapter plate of the machine tool, and the two mounting surfaces are in the same shape as the disk. The inclination angle of the chute to be processed of the workpiece is set at the same angle, and the said indexing ...

The invention discloses a tooling fixture for circumferentially processing uniformly distributed inclined grooves on disc workpieces, which comprises a supporting frame, an indexing plate and a device for fixing the disc workpieces to be machined with inclined grooves on the indexing plate. Assemblies, the indexing plate is installed on the mounting surface of the supporting frame through the indexing mechanism and the locking and fixing mechanism. The mounting surface on the adapter plate, and the angle between the two mounting surfaces is set at the same angle as the inclination angle of the chute for the disk workpiece to be processed. The tooling fixture of the present invention adopts a thread pair locking structure to lock and fix the indexing plate on the mounting surface of the support frame, which eliminates the gap between the support frame and the indexing plate, improves the equivalence accuracy of the tooling, and is reliable in positioning and easy to operate. The utility model is simple and practical, greatly improves the processing efficiency, and solves the problem that the prior art indexing fixture cannot be used to process evenly distributed inclined grooves in the circumferential direction of the disc workpiece.
Description
technical field [0001] The invention relates to the technology of uniform indexing processing of circular workpieces along the circumferential direction, in particular to a tooling fixture used for uniform indexing processing of disc workpieces along the circumferential direction. Background technique [0002] A simple mechanism is often used to process a circular workpiece with uniformly distributed holes along the circumferential direction. The fixture is composed of a base plate and an indexing plate. The mandrels on the upper plate are rotated and assembled together. A series of evenly distributed indexing holes corresponding to the uniformly distributed holes to be processed are designed on the indexing plate. There is an indexing hole on the same diameter as the indexing plate on the bottom plate. Corresponding to the positioning hole, rotate the indexing plate, so that the positioning hole on the base plate corresponds to the different indexing holes on the indexing p...
