In the production of our factory, we often encounter the processing of fork head parts. Due to the high verticality requirements of the threaded holes and side holes of the fork head, in order to meet the design requirements, we have designed an effective and simple tooling to use the effect on the product. good. Figure 1 shows a fork made by our factory, material ZG230-450. The technical requirements are: the concentricity error of the two sides is not more than 0.05mm, the threaded hole is at the center of both sides, and the perpendicularity error with the two side holes is less than 0.03mm. The method is to first process the side plane and the side hole, and then machine the threaded hole. The two sides can be processed on the four-claw single-action chuck of the sleeper, and the concentricity is easy to ensure. When machining a threaded hole, how to ensure the perpendicularity of the thread and the side hole is the key. The structure of the fixture is shown in Figure 2. The fixture passes the sleeper wheel guide key 2 and positioning.
