AI Technical Summary

Technical Problem

In the prior art, the positioning accuracy of the central positioning structure is insufficient, the operation is complicated, and the positioning components are difficult to reset, making it difficult to adapt to workpieces with complex shapes or variable sizes.

Method used

A central positioning structure is adopted, including a fixed set, driver header and Zhouxiang positioning component. The fixed sleeve is equipped with a pass and sliding holes. The driver head is connected to the pores by sliding, and the positioning column moves to the outside through the resistance of the connection column to the connection column to achieve the center positioning of the center. The Zhouxiang positioning component consists of a ring elastic part and a positioning column. When the positioning column is not replaced without the drive head, the elasticity of the ring elastic part is reset.

Benefits of technology

Improve the accuracy and stability of the central positioning, ensure that the workpiece can be accurately located in the center position, and simplify the reset process of the positioning component, and improve the efficiency of work.

Abstract

The utility model provides a center positioning structure which is characterized in that a through hole is formed in a fixing sleeve, a plurality of sliding holes are formed in the circumferential direction of the fixing sleeve at equal intervals in the radial direction of the fixing sleeve, and all the sliding holes penetrate through the through hole; the driving head is slidably connected into the through hole, and one end of the driving head is provided with an abutting head. The circumferential positioning assembly comprises an annular elastic piece and a plurality of positioning columns. The number of the positioning columns is consistent with that of the sliding holes; all the positioning columns correspond to the sliding holes one by one; the annular elastic piece is tightly hooped on the fixing sleeve, the annular elastic piece is connected with one ends of all the positioning columns at equal intervals in the circumferential direction, the other end of each positioning column is connected to the sliding hole in a sliding mode, and the inward end of each positioning column is provided with an abutting portion matched with the abutting head. According to the utility model, by moving the driving head, the abutting head of the driving head is in contact with the abutting part of each positioning column, so that each positioning column moves towards the outer side of the fixing sleeve along the sliding hole, and the central positioning of a workpiece sleeved on the fixing sleeve is realized.
