A welding jig

Abstract

The invention discloses a welding fixture, and relates to the field of work fixtures. A clamping roller is mainly used for extruding and loosening a bar-shaped bag, so that the bar-shaped bag absorbsalcohol and sprays alcohol outwards; when the clamping roller is driven by a motor to rotate forwards to push against a workpiece, the bar-shaped bag absorbs alcohol from a storage box after losing the extrusion effect of the clamping roller; and when the clamping roller is driven by the motor to rotate reversely, the clamping roller drives the workpiece to move downwards, the bar-shaped bag is extruded again by the clamping roller and sprays alcohol towards the workpiece moving downwards. The welding fixture solves the problem that a traditional welding fixture cannot adapt to workpieces of different sizes, is incapable of washing the workpiece in a welding process and is mainly used for welding of the workpiece.

Description

Technical field [0001] The invention relates to the field of tooling fixtures, in particular to a welding fixture. Background technique [0002] Welding fixture is a fixture used to ensure weldment size, improve assembly accuracy and efficiency, and prevent welding deformation. [0003] At present, the welding fixtures on the market are all fixed and cannot perform multi-angle welding work flexibly, thus failing to fully meet the requirements in operation, which increases the difficulty of welding work. Moreover, the general welding fixture can only weld one kind of large or small object. When welding large or small objects at the same time, two welding fixtures are used, which is very inconvenient to take and weld. It is very inconvenient for different shapes and sizes. The objects need to be replaced with different fixtures; [0004] After the welding is completed, the residual flux on the weldment is generally cleaned with alcohol to prevent the carbonized flux from affecting th...

AI Technical Summary

Problems solved by technology

[0003] However, the welding fixtures currently on the market are fixed and cannot perform multi-angle welding work flexibly, so that they cannot fully meet the requirements of the operation and increase the difficulty of welding work.

And the general welding jig can only weld one kind of large or small objects. When welding large or small objects at the same time, two welding jigs should be used, which is very inconvenient to take and weld. The object needs to be replaced with a different fixture;

[0004] After the welding is completed, it is generally necessary to clean the residual flux on the weldment with alcohol to prevent the carbonized flux from affecting the normal operation of the weldment. At present, the weldment that has been welded is generally removed, and then the weldment cleaning, resulting in low cleaning efficiency
