AI Technical Summary

Technical Problem

Traditional three-claw chuck clamps can easily block the processing area when clamping the outer circle of the bushing. When both ends and outer walls need to be processed, they need to be disassembled and adjusted repeatedly to affect the processing efficiency.

Method used

A circular bushing positioning tool is designed to tighten the bushing through the inner hole, and a combined structure of core tube, screw, conical block, press plate and elastic ring is used to fix its position from the inside of the bushing, making the outside completely exposed, making it convenient for processing.

Benefits of technology

Complete exposure of the outer part of the bushing is achieved, avoiding occlusion of the processing area, simplifying the adjustment of the bushing position and improving processing efficiency.

Abstract

A circular lining positioning tool comprises a core tube, a screw rod, a conical block, a pressing plate and an elastic ring. A plurality of strip-shaped holes formed in the length direction are formed in the side wall of the core tube, and the strip-shaped holes are formed along the circumference of the core tube in an array manner; the screw rod is coaxially and rotatably arranged in the core tube, and external threads with opposite screwing directions are arranged at the two ends of the screw rod; the number of the conical blocks is two, the conical blocks are coaxially arranged in the core tube in a sliding mode, the conical tops of the conical blocks face the middle of the core tube, the two ends of the screw penetrate through the two conical blocks respectively, and the screw is connected with the conical blocks through external threads; the number of the pressing plates is consistent with that of the strip-shaped holes, the pressing plates penetrate through the strip-shaped holes respectively, the outer side edges of the pressing plates are parallel to the core tube and face the outside of the core tube, and the two ends of the inner sides of the pressing plates are provided with slopes matched with the conical surfaces of the conical blocks; and the elastic ring sleeves the outer sides of all the pressing plates and is used for applying pressure towards the axis of the core tube to the pressing plates. According to the scheme, the lining is pressed and fixed through the inner hole, the outer portion of the lining is prevented from being shielded, and the outer wall of the lining can be machined conveniently.
