SUMMARY

[0003] The technical problem to be solved by the utility model is to provide a kind of tooling for processing valve body fixture, it can bring convenience to the clamping and processing of valve body fixture, and can improve the machining precision of valve body fixture.

[0004] The utility model provides a kind of tooling for processing valve body fixture, including zero point positioning base;Tooling further includes the support block for supporting the valve body fixture to be processed, valve body fixture is fixed at the upper end of support block;The middle part of the lower end of support block is vertically fixed with first positioning column, and the lower end surface of support block and located the both sides of first positioning column are vertically fixed with first positioning pin, first positioning column is used to cooperate with the positioning hole in the middle part of zero point positioning base and is inserted, each first positioning pin is used to cooperate with one of the positioning slot on zero point positioning base and is inserted;The middle part of the right end of support block is horizontally fixed with second positioning column, and the right end surface of support block and located the both sides of second positioning column are horizontally fixed with second positioning pin;When second positioning column cooperates with the positioning hole in the middle part of zero point positioning base and is inserted and in second positioning pin cooperates with one of the positioning slot on zero point positioning base and is inserted, tooling is used to change the machining direction of valve body fixture.

[0005] By adopting the above structure, when the valve body fixture undergoes the first-order cutting process at the machining center, the first positioning pin is inserted into the positioning hole located in the middle of the zero-point positioning base, and each first positioning pin engages with one of the positioning slots on the zero-point positioning base. At this time, the zero-point positioning base can clamp the first positioning pin, and the first positioning pin and the positioning slot can achieve circumferential positioning of the support block and the zero-point positioning base. When the valve body fixture needs to undergo the second-order cutting process, the second positioning pin is inserted into the positioning hole located in the middle of the zero-point positioning base, and each second positioning pin engages with one of the positioning slots on the zero-point positioning base. At this time, the zero-point positioning base can clamp the second positioning pin, and the second positioning pin and the positioning slot can achieve circumferential positioning of the support block and the zero-point positioning base. That is, when the valve body fixture is clamped in the second order, the valve body fixture does not need to be repositioned, which can facilitate the clamping and processing of the valve body fixture and improve the processing accuracy of the valve body fixture.

[0006] In one possible implementation, the support block has a countersunk hole through which a bolt passes from bottom to top. A threaded hole is located in the middle of the lower end of the valve body fixture. The bolt is threaded into the threaded hole to secure the valve body fixture to the upper end of the support block. A circumferential limiting structure is provided between the valve body fixture and the support block. With this structure, after the bolt is threaded into the threaded hole, the valve body fixture to be processed can be reliably secured to the support block. Furthermore, due to the circumferential limiting structure between the valve body fixture and the support block, rotation of the valve body fixture relative to the support block can be effectively prevented during machining at the machining center, thus achieving reliable fixation of the valve body fixture.

[0007] In one possible implementation, the circumferential limiting structure includes several circumferentially evenly distributed limiting posts fixed to the lower end of the valve body clamp. Each limiting post extends vertically, and the upper end of the support block is provided with a limiting hole that corresponds vertically to each limiting post. Each limiting post is vertically inserted into the limiting hole at the corresponding position. By adopting this structure, after each limiting post is vertically engaged with the limiting hole at the corresponding position, the valve body clamp and the support block can reliably achieve the purpose of circumferential limiting, that is, it can effectively prevent the valve body clamp from rotating relative to the support block.
