Back liner tool for automatic welding production line

Abstract

The invention provides a back liner tool for an automatic welding production line. A first stand column assembly, a second stand column assembly, a first trolley platform, a second trolley platform, aback liner trolley walking between the first stand column assembly and the second stand column assembly, a guiding mechanism, a first traction mechanism and a second traction mechanism are included,wherein the first trolley platform and the second trolley platform are arranged on the first stand column assembly and the second stand column assembly correspondingly. The guiding mechanism comprisesa guiding steel wire rope winch assembly and a guiding steel wire rope wound and unwound through the guiding steel wire rope winch assembly, and the movement of the back liner trolley is guided. Thefirst traction mechanism and the second traction mechanism are arranged on the first stand column assembly and the second stand column assembly correspondingly, a dragging steel wire rope pulls the back liner trolley to move in the direction of the first trolley platform and the second trolley platform. The automatic back liner tool with better accuracy, usage flexibility and applicability is provided and is particularly suitable for plasma composite welding work.

Description

technical field [0001] The invention relates to the field of welding tooling technology, in particular to a backing pad tooling used in an automatic welding production line. Background technique [0002] In welding, many welds with high quality requirements, especially butt welds, need to be formed on both sides. The general practice is to weld on one side and then clean the back and then weld on the other side. To improve welding efficiency, single-sided welding is usually used The way of double-sided molding. To achieve single-sided welding and double-sided forming, it is necessary to add a backing pad on the back of the weld to assist in the formation of the weld. The conventional backing pad is a copper plate, and the workpiece is placed on the copper plate. After the welding is completed, the workpiece is removed. However, this kind of backing pad is only suitable for flat plate or workpieces with short welding seam. It is difficult to realize the cylindrical long wel...

Problems solved by technology

However, the magnetic trolley of this scheme moves along the weld seam only by pulling the traction wire rope on one side, the accuracy of its displacement is difficult to guarantee, and it can only move in one direction, and the flexibility of use is not high.

In addition, the column structures of the first lifting guide assembly and the second lifting guide assembly are fixed, so the distance between them is also fixed. When welding workpieces of different lengths, the columns need to be disassembled again, and the installation The workpiece is also easy to interfere with the structure, and the applicability of the device is poor
