Automatic production line, welding equipment and positioning clamp of welding equipment

Abstract

The invention discloses an automatic production line, welding equipment and a positioning clamp of the welding equipment, the positioning clamp comprises a clamping mechanism and a centering mechanism, the clamping mechanism is used for abutting against the inner side of channel steel of a to-be-machined workpiece from inside to outside in the first direction, and the centering mechanism is used for centering the clamping mechanism; the centering mechanism is used for abutting against the outer side of channel steel of the workpiece to be machined from outside to inside in the first direction. According to the positioning clamp, outward deformation of welding can be avoided to the greatest extent.

Description

technical field [0001] The present application relates to the technical field of clamping and positioning, and in particular to a positioning fixture. It also relates to a welding device. It also relates to an automated production line. Background technique [0002] The mast is an important part of an industrial forklift. It usually includes an inner mast, a middle mast and an outer mast. The outer mast is fixed on the outermost side. The inner mast and the middle mast are placed inside the outer mast. The upper end is equipped with a lifting cylinder, and the lower end of the inner mast is equipped with a cargo fork, which is driven by the lifting cylinder to carry out lifting operations. [0003] The structure of the outer mast and the inner mast is similar, and they are composed of two left and right channel steels and corresponding beams arranged above the channel steels, which are riveted and welded structural parts. During welding, the door frame is automatically cl...

AI Technical Summary

Problems solved by technology

When welding, use the fixture to automatically clamp the door frame, and then weld at the position where the channel steel and the beam are connected. Under the action of welding stress, it is easy to open to the outside, resulting in welding deformation

The inner mast and the outer mast need to be accurately matched, so the size of the welded workpiece has high requirements. However, the traditional fixture is in the form of fixing one side and moving the other side to the outside of the channel steel, which cannot avoid welding deformation. Due to the situation, the deviation of the workpiece is very large after the welding is completed, so it has to be corrected in the width direction after the welding is completed, which increases the workload
