[0029] Below, embodiments of the present invention are described in detail with reference to the accompanying drawings. To make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0030] Therefore, the following detailed description of the embodiments of the present invention provided in conjunction with the accompanying drawings is not intended to limit the scope of the present invention for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present invention.

[0031] Example 1

[0032] like Figure 1-Figure 4 As shown, the thrust plate heat treatment tooling provided in this embodiment is mainly used to fix the thrust plate 100 and then send it into a baking oven for heat treatment. It is mainly composed of a connecting rod body 10, two pressing plates 20 sleeved on the connecting rod body 10, two connecting sleeves 30 sleeved on the connecting rod body 10, and four limiting rod bodies 40 arranged between the two pressing plates 20. The thrust plate 100 is stacked between the two pressing plates 20, and the connecting sleeve body 30 can move and lock on the connecting rod body 10. The connecting sleeve body 30 is used to push the pressing plate 20 toward the thrust plate 100. The four limiting rod bodies 40 surround the thrust plate 100 and fit with the outer wall of the thrust plate 100. Therefore, a clamping space that can stably clamp the thrust plate in the center is formed between the two pressing plates 20 and the four limiting rod bodies 40.

[0033] Specifically, the pressure plate 20 is disc-shaped, and a plurality of anti-skid grooves are arranged in the pressure plate 20 on the side facing the thrust plate 100. The anti-skid grooves include two first groove bodies 21 and a plurality of second groove bodies 22. The two first groove bodies 21 are straight and cross-arranged, and the plurality of second groove bodies 22 are concentrically arranged. The intersection point of the two first groove bodies 21 coincides with the center of the second groove body 22, and the center of the second groove body 22 coincides with the center of the pressure plate 20.

[0034] Thus, the end surface of the pressure plate 20 is divided into a plurality of fan rings 201 by the anti-skid grooves, and the fan ring 201 structure contacts the thrust plate 100 to enhance the friction force and avoid scratches.

[0035] Furthermore, the side surfaces of the pressing plate 20 are evenly provided with tooth-shaped anti-slip grooves 240 to provide locking and fixing inside the oven.

[0036] Furthermore, the connecting sleeve 30 and the connecting rod 10 are threadedly matched, that is, the connecting rod 10 can adopt a screw structure, and the connecting sleeve 30 adopts a nut structure.

[0037] Furthermore, a boss 230 is provided at the center position of the opposite sides of the two pressure plates 20, the connecting rod body 10 passes through the boss 230, the connecting sleeve body 30 is provided on the boss 230, and an elastic gasket 50 is provided between the boss 230 and the connecting sleeve body 30, and the elastic gasket 50 is pressed between the boss 230 and the connecting sleeve body 30.

[0038] Furthermore, one of the pressure plates 20 is provided with a plurality of plug-in slots 210, and the other pressure plate 20 is provided with a plurality of plug-in holes 220. One end of the limiting rod body 40 is inserted into the plug-in slot 210 and the other end can pass through the plug-in hole 220, that is, the other pressure plate 20 can move on the limiting rod body 40, thereby being able to adapt to thrust plates of different numbers and thicknesses. Of course, plug-in slot structures can also be provided on both pressure plates 20, that is, the distance between the two pressure plates 20 is fixed, so as to adapt to the quick and stable clamping of thrust plates of the same specification.
