现介绍两种在车床上车制薄片形零件胎具,此胎具制作方便,使用效果较好,能提高生产效率,保证零件的加工精度。 1.内孔带有螺纹的薄片形零件加工内孔有螺纹的薄片零件可制成如图1的胎具。此胎具由开口套、弹簧、弹簧柱组成,使用时将零件拧在弹簧柱上,推紧弹簧柱,使零件与开口套端面贴紧,卡紧三爪,通过弹簧作用将弹簧柱推出,零件可 Are introduced in the lathe car sheet-shaped parts car tires, the carpets easy to make, the use of better, can improve production efficiency and ensure the accuracy of parts processing. 1. Inner hole with a thin sheet-shaped parts Machined in-hole threaded sheet parts can be made as shown in Figure 1 of the tire. The utility model is composed of an opening sleeve, a spring and a spring column. When the utility model is used, the part is screwed onto the spring column to push the spring column tightly so that the part is tightly clamped with the opening sleeve, clamping the three claws, pushing the spring column out by a spring, Parts can be
