This is a kind of fixture which can be used in batch high efficient drilling or milling. It can not only drill down the ordinary hole, but also can drill several holes of the same degree or different degrees, once in a clip, and the position is fast and accurate. It can also drill the hole, the drill cone face or the hole with the taper vertical. It can also be used to milling plane or groove on the outer circle, milling the slot on the end surface. This figure is horizon

按此原理，改变一下座体形状和后面手轮结构，就变成立式，不但可以在钻床上钻圆周孔（如法兰孔）和位置孔，还可以铣位置槽或正多边形，或非正多边形。

According to this principle, the change of body shape and structure of the handwheel behind, they became vertical, not only can be circular holes on the drilling machine, such as flange hole) and location hole, can also milling groove position or regular polygon, or a regular polygon. 

如要更换加工零件，只需更换夹簧和拉杆就行了。如要改变加工零件的孔或平面位置，重新做一个分度盘就行了。

If you want to change the machining parts, just replace the spring and pull rod. If you want to change the hole or plane position of the processed parts, you can redo a dividing disk. 

此图用的是涨簧，涨夹零件的内孔。要夹零件的外圆，使用的是夹簧，结构简单些，拉杆和夹簧是一体的。

This diagram USES the inner hole of the rising spring and the clip part. To clip the outer circle of the part, use the clip spring, the structure is simple, the pull rod and the clip spring are one.  

由于可装钻模，加工的孔的精度较高，分度盘采用楔形定位，压簧压紧，分度精度较高，分度盘精度出现误差修正简单方便，而且可以修正到较高的位置精度。我们厂有很多使用了多年的高效夹具，可以说都是设计很成熟的夹具了。可惜的是我没留图纸，凭记忆画此图时发现，几乎等于从新设计了一遍，真的劳不起那个神了。

The hole can be loaded, the diamond processing of high precision, dial the wedge orientation, compression spring compression, dividing precision, precision indexing plate appear simple error correction, and can be fixed to the higher position precision. Our factory has many many years of high efficiency jig, can be said to design very mature jig. Unfortunately, I didn't leave the drawing, and when I drew it from memory, it was almost as if I had redesigned it, and I really couldn't afford it.
