我厂制造7.5M卫星接收天线馈源如图2,由于受到设备限制,只能在C666车床上加工。普通车床加工双曲旋转面,车工只能靠手动进刀,用样板反复校对,操作十分麻烦,双曲线面难加工准确,粗糙度无法达到要求。鉴于上述情况,笔者设计了一个装置,装在C666车床的大拖板上,与车床的横向自动进给配合使用。经实践证明,使用装置加工出来的工件,双曲旋转面平整光滑,用砂纸稍加打磨即可达到要求。提高工效5～8倍。现介绍如下。
I plant 7.5M satellite receiver antenna feed shown in Figure 2, due to equipment constraints, only in the C666 lathe processing. Ordinary lathe machining hyperbolic surface of rotation, only by manual turner, the model repeatedly proofing, the operation is very troublesome, hyperbolic difficult to accurately handle the surface roughness can not meet the requirements. In view of the above situation, I designed a device that is mounted on the C666 lathe of the large carriage, with the lathe horizontal automatic feed with the use. Practice has proved that the workpiece using the device out of work, hyperbolic rotating surface smooth, slightly polished with sandpaper to meet the requirements. Improve work efficiency 5 ~ 8 times. Now introduced as follows.
