这种新式铣床夹具,具有机械式液压定位支承元件(见苏联发明证书3685827)。采用这种夹具时,不但可以简化被加工零件的装夹定位过程,而且还能提高工作质量和工作的安全可靠性。夹具在使用时,先把被加工零件放在能起预定位(定向)作用的V型垫铁1、3中。从动力源11来的动力推动顶杆10,并同时带动液压支承块2和液压顶尖4。弹簧9的力应这样来选择,当液压支承块的表面与待夹紧的零件相接触时,应使液压顶尖不完全进入被加工零件的中心孔。当顶杆10向锥套8内滑动时,锥套8在弹簧9作用下
This new milling machine fixture, with mechanical hydraulic positioning support elements (see the Soviet Union invention certificate 3685827). The use of this fixture, not only can simplify the process of clamping the workpiece positioning process, but also improve the quality of work and work safety and reliability. Fixture in use, the first to be processed parts can play a pre-positioning (orientation) role in the V-shaped horn 1,3. Power from the power source 11 pushes the jack 10 and at the same time drives the hydraulic block 2 and the hydraulic tip 4. The force of the spring 9 should be chosen so that the hydraulic tip does not fully enter the center hole of the part to be machined when the surface of the hydraulic support block comes into contact with the part to be clamped. When the mandrel 10 is slid into the sleeve 8, the sleeve 8 is under the action of a spring 9
