Positioning device of irregular part

Abstract

The invention discloses a positioning device of an irregular part. The positioning device of the irregular part comprises a base and a clamp. The base is provided with a fixing rod used for fixing workpieces and an equal altitude cushion block, and the equal altitude cushion block is provided with a first through hole. The clamp comprises a pressing plate, a clamping plate and an L-shaped base plate, wherein the L-shaped base plate and the pressing plate are connected in a threaded mode, the clamping plate is placed between the L-shaped base plate and the pressing plate, and one end of the pressing plate is provided with a compressed spring which abuts against the L-shaped base plate. A second through hole which is placed over the first through hole is formed in the pressing plate, and the size of the second through hole is matched with that of the first through hole. The positioning device of the irregular part overcomes the defects that the irregular part with two through holes can not be clamped alone, and a plurality of clamps are needed for cooperative using in the prior art. The improved positioning device of the irregular part is provided, and the positioning device of the irregular part is simple in structure, rapid in clamping and capable of conducting mass processing.

Description

technical field [0001] The present invention relates to a mechanical processing device, in particular to a positioning device for special-shaped parts. Background technique [0002] In machining operations, it is more and more necessary to quickly and accurately position parts. This can eliminate the adjustment of the fixture device as much as possible, especially when performing large-scale processing, the effect is more obvious. However, in mechanical manufacturing, there are Many special-shaped parts, such as special-shaped parts with large through-holes and small through-holes, do not have a separate auxiliary clamping tool, resulting in slow processing speed for such parts, troublesome clamping, prolonging the processing time, and the parts are difficult to be accurate. Positioning and reliable clamping increase the processing difficulty. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an improved positioni...
