When milling the cylindrical parts, our factory adopts the universal adjustable milling fixture. The fixture consists of the bottom plate 1 (with photos), the positioning baffles 4, 6, and the V-shaped slider 8. The briquetting block composed of the V-shaped and square sliders is an important part of the clamping and clamping of the clamps. They are positioned by the positioning baffles 4 and 6 on both sides, and slide on the bottom plate 1. Before the unstressed, the briquetting sets are mutually Under the action of the spring, keep a certain distance to place the workpiece. The clamping bolt of the top block 13 adopts a large pitch trapezoidal thread, which saves power and is clamped.
