Embodiment Construction

[0016] The structure of the parts to be processed by the clamping device has a typical ∏-shaped structure, such as figure 1 As shown, part 1 not only has grooves on the upper surface, but also has grooves on both sides. Secondly, the parts are elongated parts, the overall rigidity of the parts is poor, the parts are easily deformed during processing, and the size of the parts is difficult to guarantee. The processing of the parts must be done in four work stations, up, down, left and right.

[0017] The clamping device of the present invention is such as figure 2 As shown, the combined body of the clamp includes a left component 2 and a right component 3 and a movable pressing plate 6 fixed on the body. The left and right components are two elongated rigid components of equal height and adjacent surfaces that can be attached. The right component There is a step 8 on the outside of 3 which is lower than the height of the module. There are a plurality of detachable stop pins 4 on t...

Abstract

The invention discloses a Pi-type section bar numerical control machining clamping device and a clamping method thereof. The clamping device comprises a combination body and a pressing plate structure fixed on the body, wherein the combination body is formed by two left and right equal-height strip-shaped stiff members the adjacent surfaces of which can be bound. The invention has the advantages that the clamping device has simple structure, and a set of clamping devices can be flexibly combined to clamp upper, lower, left and right four stations of Pi-type section bars.

Description

Technical field [0001] The invention relates to the field of mechanical processing, in particular to a clamping device and a clamping method for processing ∏ profile parts in numerical control processing. Background technique [0002] At present, in the field of CNC machining, with the continuous development of CNC machining technology, the efficiency of CNC machining has been greatly improved, and higher requirements are put forward for the auxiliary preparation time of parts before machining and the safety and reliability of parts clamping and positioning. With the continuous improvement of processing efficiency, the percentage of time occupied by the auxiliary clamping of parts in the entire processing process of the parts is getting higher and higher, which has become one of the key factors hindering the improvement of CNC machining efficiency. How to clamp parts efficiently, safely, reliably and quickly and shorten the auxiliary clamping and positioning time of parts CNC mac...
