CK-ⅡNumerically-controlled machine tool headstock horizontal type two-sided combination boring lathes and jig design
ABSTRACT
The bidirectional horizontal-type combination boring lathe design mainly includes the horizontal-type single location two-sided combination boring lathe kinematic scheme the design and the multi-axle-box design, the jig, the cutting tool guide design and the clamp choice. The horizontal-type single location two-sided combination boring lathe kinematic scheme's design and the multi-axle-box design, the jig, the cutting tool guide's design and clamp's choice is aggregate machine-tool's key component, is guarantees the working accuracy the key component. It and engine bed's other parts has and the close relation. Therefore, the request aggregate machine-tool must have the good rigidity and the enough clamping force, guaranteed that the work piece does not have the displacement in the entire processing process. At the same time, satisfies the work piece processing each specification, must guarantee the work piece does not permit the distortion, raises the productivity and reduces the production cost. The technology capability and the usability is friends with. by the processing components' technological conditions is the thick boring, therefore uses at the same time both sides boring, not only processes conveniently, moreover the production efficiency is high, therefore uses the two-sided horizontal-type combination boring lathe to carry on the processing is reasonable.
According to the processing components' processing characteristic, choice two take the localization datum at the same time, the limit work piece in processing time six degrees-of-freedom. In order to guarantee that the pointing accuracy and the stability, use the bottom plane localization. The positioning pin uses the manual swiveling mechanism positioning pin, with the support plate positioning system, it uses the cylinder realizes positioning pin's insertion after the throwout lever and a series of release levers and draws out.
KEY WORDS: The bidirectional horizontal-type combination boring lathe,kinematic scheme,the cutting tool guide,the thick boring,two take the localization datum
