Problems solved by technology

[0002] The key connection is more and more widely used in mechanical equipment. In view of the rapid development of my country's industry, the mechanical manufacturing process is getting higher and higher. The position of the half-round key in the positioning of mechanical connection is becoming more and more important, and the demand is also increasing. The current half-round key processing mainly adopts the traditional turning process. Since one of the outer surfaces of the half-round key is semi-circular, it is inconvenient in the process of clamping and positioning it, which affects its automatic processing process and its production. The efficiency is relatively low and cannot meet the needs of large-scale processing and production

Abstract

The invention provides a special fixture and operation method for high-efficiency half-round key manufacturing. A frame is fixed on the top side of the bottom plate of the fixture, a bottom support seat is arranged on the inner wall of the middle part of the frame, and a top support is arranged on the inner wall of the top of the frame. seat; the inside of the top support seat is installed with a special fixture shell through rotation, and the inner set of the special fixture shell is fixed with a workpiece positioning mold, and the bottom end of the workpiece positioning mold is rotatably supported on the bottom support seat; the workpiece positioning mold is used to drive its rotation. The rotating power device is connected; the top of the workpiece positioning mold is equipped with an auxiliary support structure; the workpiece positioning mold is located on the inside of the special fixture shell and has a length of evenly distributed V-shaped positioning grooves; the V-shaped positioning grooves are matched with the clamping mechanism. ; The clamping mechanism cooperates with the clamping drive mechanism installed on the special fixture shell to realize the automatic clamping and loosening of the workpiece.

Description

technical field [0001] The invention relates to a high-efficiency semicircular key manufacturing special fixture and an operating method, and belongs to the field of machining equipment. Background technique [0002] The key connection is more and more widely used in mechanical equipment. In view of the rapid development of my country's industry, the mechanical manufacturing process is getting higher and higher, the semi-circular key is becoming more and more important in the positioning of mechanical connection, and the demand is also increasing. The current semi-circular key processing mainly adopts the traditional turning process. Since one of the outer surfaces of the semi-circular key is semi-circular, there is inconvenience in the process of clamping and positioning it, which in turn affects its automatic processing process and its production. The efficiency is relatively low, and it cannot meet the needs of large-scale processing and production. SUMMARY OF THE INVENTI...
