为提高齿轮精度和减少磨齿量,我们设计了分度圆自动夹紧夹具,见图1。 1.夹具的工作原理与结构该夹具由夹具体1、销轴2、螺杆3、拉簧4、轴承5等组成。操作时,转动压紧环7,定位销8在弹簧6的作用下,紧靠压紧环7偏心的最远点,直径为最大。此时,将零件装入夹具,零件定位后,松开压紧环,并在拉簧4的作用下转动,由于偏心R的作用推动定位销,对工件施加压力,从而夹紧工件。在加工过程中,由于拉簧拉力的方向与工件的磨削受力方
In order to improve the gear accuracy and reduce the amount of gear wear, we designed the indexing circle automatic clamping fixture, shown in Figure 1. 1. Fixture working principle and structure The fixture by the clamp body 1, pin 2, screw 3, extension spring 4, bearing 5 and other components. Operation, the rotation of the clamping ring 7, the positioning pin 8 under the action of the spring 6, abutting the center of the pressing ring 7 eccentric point, the maximum diameter. At this point, the parts into the fixture, the parts positioning, release the compression ring, and the role of the spring 4 under the rotation of the role of eccentric R push the positioning pin, the workpiece to exert pressure to clamp the workpiece. In the process of processing, due to pull the spring tension and the workpiece grinding force
