Square tube nut welding tool

Abstract

The invention discloses a square tube nut welding tool. The tool comprises partition columns, limiting blocks, square tubes, nuts and pressing strips, the partition columns are horizontally arranged on a base at intervals, the limiting blocks are vertically arranged at the two sides of the upper end face of the base, the partition columns and the limiting blocks are arranged in parallel, gaps areformed between the partition columns and the limiting blocks, and the square tubes are horizontally inserted into the gaps. The pressing strips are erected on the limiting blocks at the two ends, theplurality of nuts arranged in the length direction of the square tubes are placed on the square tubes, and the pressing strips are arranged according to the number of the nuts on the square tubes. According to the square tube nut welding tool, the nuts to be welded are placed on the square tubes provided with stepped grooves, the nuts can be prevented from horizontally moving in the welding process, the pressing strips press the nuts on the multiple square tubes along the center lines of the nuts, and the situation that the nuts collide with a mechanical arm and pop out of the stepped groovescan be prevented; and meanwhile, the positions of the pressing strips can be freely adjusted according to the positions of the nuts, welding efficiency is improved, the defective rate is reduced, andproduction time is shortened.

Description

technical field [0001] The invention belongs to the technical field of metal parts processing, and in particular relates to a square tube nut welding tool. Background technique [0002] In mechanical processing, it is often necessary to weld nuts on the surface of square tubes to fit bolts for use. The traditional manual welding method is inefficient, the welding quality is not uniform, and it cannot be mass-produced; although the existing manipulator welding method has high welding efficiency , but the method of directly placing the nut on the square pipe for welding, the nut is prone to displacement during the welding process, which makes the whole square pipe scrapped, increases the production cost, and has a high defective rate. Therefore, a solution is needed to solve the above problems. [0003] It should be noted that the above content belongs to the scope of the inventor's technical cognition and does not necessarily constitute the prior art. Contents of the inven...
