Horizontal adjusting mechanism for welding fixture

Abstract

The invention provides a horizontal adjusting mechanism for a welding fixture, which comprises a load-bearing pad, an adjustable bolt, a lock nut, a rivet, a connecting sheath and a gasket, wherein the adjustable bolt is connected with the load-bearing pad through the rivet; the rivet upwardly penetrates out of a through hole on the bottom of the load-bearing pad and is connected with a connecting hole at the lower end of the adjustable bolt; the rivet is sleeved with the connecting sheath; the connecting sheath is positioned in the through hole of the load-bearing pad; an interval is reserved between the connecting sheath and the through hole wall; the upper end of the connecting sheath props against the bottom surface of the adjustable bolt; and the lower end thereof props against the gasket of the rivet head, so that the adjustable bolt and the load-bearing pad are integrated into a whole, the safety is improved, and the adjustable bolt is enabled to have micro-space for moving right and left relative to the load-bearing pad, thus the adjustment is convenient. The mechanism can move the wielding fixture up and down by the rotation of the adjustment bolt or the adjustable bolt, thereby achieving the purpose of horizontal adjustment of the wielding fixture; the structure of the invention is simple and compact, and the arrangement is convenient; and the utilization is safety and reliable.

Description

technical field [0001] The invention relates to a level adjustment mechanism for a welding fixture. Background technique [0002] At present, in the automobile manufacturing process, the dimensional accuracy of the welded body directly affects the performance and strength of the vehicle body, and the dimensional accuracy of the welded body is related to the structure of the welding jig and the installation accuracy of the welding jig. Usually, the level of the welding jig The adjustment adopts the structural form of bolts and load-bearing pads. [0003] join figure 1 , the horizontal adjustment mechanism of the existing welding fixture is mainly composed of a load-bearing pad 1, an adjusting bolt 2 and a lock nut 3. The adjusting bolt 2 is installed on the load-bearing pad 1, and the welding fixture is clamped up and down by two lock nuts 3. On the adjusting bolt 2, by adjusting the adjusting bolt 2 or the lock nut 3, the position of the welding fixture can be adjusted up ...

AI Technical Summary

Problems solved by technology

However, in this mechanism, the adjusting bolt 2 and the load-bearing pad 1 adopt a split structure. It can achieve the ideal effect, but when the bottom surface is slightly uneven, the adjustment bolt 2 cannot be perpendicular to the ground, and the welding fixture is also difficult to adjust to the level, which makes it time-consuming and laborious to install the welding fixture, and it is also unstable.

[0004] It can be seen that there are still many deficiencies in the existing level adjustment mechanism, and it is necessary to carry out further improvement
