我厂过去加工球头销上的球面油槽是在铣床上进行铣削的,操作困难,加工出的零件质量差。现在,我们制做了一个简易夹具,改在工具磨床(或砂轮机)上磨出球而油槽,经使用证明,效果很好,加工的零件质量高,提高工效10倍左右。一、夹具结构(附图) 夹具是根据圆球自身旋转原理设计的,旋转体4头部车出90°内锥面,为圆球定位夹紧用,90°内锥面与φ25d_b圆柱体同一轴线,夹持体3与旋转体4能相对转动,且无轴向移动。使
The spherical groove on the ball head pin of our factory was machined on the milling machine in the past. The operation is difficult and the quality of the machined parts is poor. Now, we made a simple fixture, change the tool grinder (or grinder) on the ball and the oil tank, the use of that effect is very good, the quality of processed parts, to improve work efficiency about 10 times. First, the fixture structure (with photos) Fixture is based on the principle of rotation of the ball itself, the body of the rotating body 4 out of 90 ° cone, positioning and clamping for the ball, 90 ° cone and φ25d_b cylinder the same Axis, the holding body 3 and the rotating body 4 can rotate relative to each other without axial movement.
