abstract

The jig body is on the drilling machine the most main components, plays the connection positioning device, the clamp, leads to roles and so on installment.

There are five chapters about the bas ic process of the drilling jig system’s technics of machining and jig design.The first chapter is about the analysis of accessory;the second chapter is about the design of accessory technics regulations;the third chapter is about the design of machine tool’s jig;the forth chapter is about the design and numeration of hydrocylinder;the fifth chapter is about the conclusion.

In the text there are some illustrations and correlative tables in order to express clearly the basic approaches of the drilling jig system in the adhibition of aborning , the process of mechanical technics’ machining and the design of machine tool’s jig.And it goes into particulars the datum plane of accessory machining,the calculating process of working procedure size,the design of jig element and what not.

Key words: jig, hydrocylinder, the drilling jig system, benchmark, working procedure size
