AI Technical Summary

Technical Problem

Since the bearing cylinder is mostly a thin-walled structure, it is prone to local deformation during the production process, resulting in a large error in the cylindricity of the bearing cylinder. The annular reinforcing ribs are difficult to move smoothly to the reinforcing position, affecting the smoothness of welding.

Method used

A positioning fixture for welding baskets is provided, including a shaping mechanism. The shaping ring and the driving structure drive the shaping ring to be inserted into the bearing cylinder, adjust the cylindricity of the bearing cylinder, and ensure the smooth movement of the annular reinforcing rib through the centering bearing structure and the lubrication mechanism.

Benefits of technology

Effectively adjust the cylindricity of the bearing cylinder to ensure that the annular reinforcing rib can move smoothly to the correct position, improve the smoothness of welding, and avoid the influence of deformation on welding.

Abstract

This utility model relates to the field of welding positioning technology, and in particular to a positioning fixture for welding cargo baskets. The device includes a shaping mechanism; the shaping mechanism includes a shaping ring frame and a driving structure; the shaping ring frame is mounted on the driving structure; the driving structure drives the shaping ring frame to move vertically downwards, so that the shaping ring frame is inserted into the bearing cylinder, thereby adjusting the cylindricity of the contact position between the bearing cylinder and the shaping ring frame; during the shaping process, the annular reinforcing rib is fitted onto the bearing cylinder along with the shaping ring frame and moves synchronously with the shaping ring frame along the surface of the bearing cylinder. When the positioning fixture for welding cargo baskets provided by this utility model is in operation, the driving structure drives the shaping ring frame to move vertically downwards, so that the shaping ring frame is inserted into the bearing cylinder, thereby adjusting the cylindricity of the contact position between the bearing cylinder and the shaping ring frame, thus solving the problem of the annular reinforcing rib being difficult to move smoothly to the reinforcing position.
