Abstract

The invention discloses a coaxiality regulating and locating device. The coaxiality regulating and locating device comprises a bottom plate and a bearing seat, wherein the bearing seat is clamped in a through hole of the bottom plate through an upper flange, and the base is fixedly connected with the bearing seat through a screw; an air cylinder is fixedly connected with the base through a stud; an ejecting block in which an I-shaped hole is formed in the middle part is in clearance fit with a differential diameter hole, a piston rod of the air cylinder stretches into the I-shaped hole and is fixed with the I-shaped hole through a nut, a locating seat is arranged in a stepped hole of the bearing seat, and two bearings are arranged in a left gap and a right gap between the locating seat and the bearing seat. According to the coaxiality regulating and locating device disclosed by the invention, a workpiece and a locating tool can be rotated together by rotating the bearings, no relative motion is generated between the workpiece and the locating tool, friction is avoided, and thus the abrasion of a locating clamp is avoided; gaps between the locating tool and the workpiece are reduced, the regulating accuracy is increased, and the one-step assembling qualified rate is improved; a pneumatic lifting device is adopted, the problem that the workpiece is clamped in the locating tool due to high accuracy of the locating tool and small matching gaps between the locating tool and the workpiece is solved, and the workpiece can be conveniently lifted.

Description

technical field [0001] The invention belongs to a positioning adjustment device, in particular to a coaxiality adjustment positioning device. Background technique [0002] Coaxiality is an important parameter to ensure the long-term and stable operation of the equipment. The current adjustment method of the workpiece coaxiality is: set the axis of the coaxiality positioning tool as the reference axis, put the workpiece to be adjusted into the coaxiality tool, Use the image measuring instrument for positioning and adjustment. In the process of adjustment and positioning, the workpiece needs to be rotated, and the different angles and coordinates of the workpiece are compared and adjusted. There are problems such as easy wear of the positioning tooling and the easy jamming of the workpiece in the tooling. Contents of the invention [0003] The present invention is proposed in order to overcome the shortcomings in the prior art, and its purpose is to provide a coaxiality adj...
