AI Technical Summary

Technical Problem

Large and heavy shaft parts are difficult to clamp during welding, with low welding accuracy and efficiency, and there is a risk of unbalanced deformation at one end of the clamping and the part slipping.

Method used

An auxiliary bracket for welding shaft parts is designed, which includes a support assembly and a fixed clamping assembly. The support assembly is equipped with an active fixed clamping assembly and a passive fixed clamping assembly. The shaft parts are firmly clamped by supporting the connecting cylinder, the clamping body and the ejector protrusion, and the stable rotation of the shaft parts is achieved through the bearing and the welding rotation mechanism.

Benefits of technology

It improves welding quality and efficiency, avoids surface scratches during welding, reduces production costs, adapts to welding shafts of different sizes and heights, and improves the availability and universality of the auxiliary bracket.

Abstract

The utility model discloses an auxiliary support for welding shaft parts, which comprises a supporting assembly with adjustable length and height, a fixed clamping assembly is mounted on the supporting assembly, the fixed clamping assembly comprises a driving fixed clamp and a driven fixed clamp which are the same in structure, the supporting assembly comprises a pair of bearings, and the bearings are connected with the driving fixed clamp and the driven fixed clamp. The driving fixing clamp and the driven fixing clamp are oppositely arranged and installed on a pair of bearings respectively, the driving fixing clamp comprises a supporting connecting cylinder, a clamping body and an ejector pin protrusion which are coaxially and integrally arranged, three clamping platforms are arranged on the clamping body, threaded through holes are formed in the movable ends of the clamping platforms, bolts are installed in the threaded through holes, and the ejector pin protrusion is arranged on the supporting connecting cylinder. According to the auxiliary support, a welding shaft can be stably clamped from the two dimensions of the axial direction and the circumferential direction, clamping traces cannot be left, the welding efficiency and quality are improved, universality is high, and the auxiliary support is suitable for being used in the welding process of the welding shaft. The production cost is reduced.
