车削不等径90°弯头,用三爪卡盘夹紧十分困难。为此,我们设计了异径直角弯头夹具。其结构合理,夹紧牢靠,通用性强。可加工几十种不同规格弯头,只更换定位块3即可。结构及原理如下:拆下四爪盘的4个卡爪,换上专用爪2(2个),再将定位块3用螺钉4紧定。使用时将工件放在任一定位块的内圆柱表面上定位,用卡盘扳手旋转丝杠5,夹紧
Turning unequal diameter 90 ° elbow, with a three-jaw chuck clamping is very difficult. To this end, we designed a different diameter right-angle elbow fixture. Its structure is reasonable, firm grip, versatility. Machining dozens of different specifications Elbow, only to replace the positioning block 3 can be. The structure and principle are as follows: Remove the four claws of the four claw plate, replace the special claw 2 (2), and then fix the positioning block 3 with the screw 4. Use the workpiece on the positioning of the inner cylindrical surface of any positioning block, use the chuck wrench rotation screw 5, clamping
