AI Technical Summary

Technical Problem

When clamping circular glass workpieces with existing fixtures, it is difficult to adjust the concentricity between the product and the machine's rotating axis, resulting in insufficient processing accuracy and affecting product yield.

Method used

The adjustable fixture center mechanism is adopted. By setting a ball plunger and a magnet between the mounting base and the positioning base, combined with the adjustment component and the tensioning fixture, the concentricity adjustment of the product and the machine rotation axis can be achieved, reducing the difficulty of concentricity adjustment.

Benefits of technology

The concentricity between the product and the machine's rotating axis is improved, the product processing accuracy and yield are improved, and the concentricity adjustment process is simplified.

Abstract

A mechanism capable of adjusting the center of a clamp comprises a mounting base, a positioning base and an adjusting assembly, the mounting base is provided with a through hole and a limiting ring communicated with the through hole, and at least one limiting groove provided with a magnet is formed in the upper surface of the mounting base; the lower surface of the positioning base is provided with an inserting groove, the upper surface of the positioning base is provided with a chuck mounting portion, the annular side face of the positioning base is provided with four first threaded holes communicated with the inserting groove, the positioning base covers the top of the mounting base and is in screw connection with the mounting base, the limiting ring is inserted into the inserting groove, and the difference between the outer diameter of the limiting ring and the inner diameter of the inserting groove is larger than 0. At least the lower surface of the positioning base is provided with a magnetic attraction part in magnetic attraction fit with the magnet; the adjusting assembly comprises four ball plungers inserted into the first threaded holes in a one-to-one correspondence mode, and ball heads of the ball plungers extend into the inserting grooves and abut against the outer surface of the limiting ring. The ball head plunger moves relative to the limiting ring when bearing external torsional force so as to adjust the position of the positioning base. The utility model further discloses a tensioning clamp comprising the mechanism capable of adjusting the center of the clamp.
