Abstract

The invention discloses a centering mechanism which comprises a frame. The frame is provided with a rack shaft capable of axially moving, the rack shaft is connected with the end of a piston rod, and an oil cylinder matched with the piston rod is fixedly connected to the frame. The frame is connected with a first swinging arm and a second swinging arm through a rotating shaft, the first swinging arm is opposite to the second swinging arm, the end of the first swinging arm and the end of the second swinging arm are connected with pressing heads, the other end of the first swinging arm is provided with teeth meshed with a rack on the rack shaft, the frame is provided with a transitional gear meshed with the rack on the rack shaft through a rotating shaft, the other end of the second swinging arm is provided with teeth meshed with the transitional gear, and a guide sleeve is arranged between the rack shaft and the frame. The centering mechanism is simple in overall structure and capable of bearing large transmission force, and centering is carried out easily and accurately with small errors.

Description

technical field [0001] The invention relates to a centering mechanism, which is used for centering and aligning workpieces in machining, so as to facilitate accurate clamping of workpieces. Background technique [0002] The workpiece needs to be transported to the tooling position before machining, and then fixed by the clamping mechanism. The accuracy of centering during fixing is very important, which affects the machining accuracy of the workpiece. At present, the centering mechanism of the workpiece is mostly a connecting rod structure, and the overall The structure is complex, it takes up a lot of space, and the bearing capacity is small. Contents of the invention [0003] The object of the present invention is to provide a centering mechanism with simple overall structure, flexible and reliable action, small error, and ability to withstand relatively large transmission force, so as to overcome the deficiencies of the prior art. [0004] The centering mechanism of th...
