Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of grinding processing, and particularly relates to a grinding processing tooling for a silicon carbide ceramic ring. Background Technique
[0002] The rejection rate of defective products with missing parts after machining of silicon carbide products is high. Silicon carbide ceramics belong to brittle materials. Since the edges and corners of the product blanks made of powder-pressed materials are all convex, during the machining process, the edges and corners of the products clamped by traditional toolings will be subjected to very large extrusion forces, resulting in damage to the edges and corners of the products. Therefore, it is an urgent problem to develop a processing tooling that can protect the edges and corners and other parts of the products during clamping. Content of the Utility Model
[0003] The purpose of the utility model is as follows:
[0004] To solve the problem that the edges and corners of the silicon carbide products are easily damaged by extrusion during clamping in the machining of existing silicon carbide products, a grinding processing tooling for a silicon carbide ceramic ring is provided.
[0005] The technical solution adopted by the utility model is as follows:
[0006] A grinding processing tooling for a silicon carbide ceramic ring includes a tooling fixed section, a tooling clamping section, and a tooling clamping component connected in sequence. The tooling fixed section includes an end fixed shaft, and the end fixed shaft is fixedly connected with a fixed chuck. The fixed chuck is fixedly connected with the tooling clamping section. The tooling clamping section is cylindrical, the diameter of the tooling clamping section is smaller than the diameter of the fixed chuck, and the surface of the tooling clamping section is covered with a plastic coating layer.
[0007] Further, one end of the tooling clamping section away from the fixed chuck is connected with an assembly screw, and the tooling clamping component is installed on the assembly screw by threads.
[0008] Further, the tooling clamping component includes a movable chuck and a fixed nut installed on the assembly screw. The shape and size of the movable chuck are the same as those of the fixed chuck, and an internal thread mounting hole matching the assembly screw is opened on the movable chuck.
[0009] Further, the plastic coating layer is a plastic soft transition layer with a thickness of 0.1 mm - 0.2 mm.
[0010] In summary, due to adopting the above technical solution, the beneficial effect of the utility model is:
[0011] The utility model focuses on the edge protection of ceramic products, adding a plastic coating layer to the tooling, which not only does not affect the stiffness of the tooling but also ensures the dimensional accuracy and quality of the processed products, effectively avoiding the chipping and defect of the edges and corners of silicon carbide products caused by direct hard contact and extrusion with the tooling fixture.
