Problems solved by technology

Since the side strips may be deformed during processing or storage, causing the side strips to be twisted, it is difficult to align the cuts of adjacent side strips during welding, which makes the welded frame deformed, making it difficult to install
In addition, during welding, due to artificial compression and fixation, there are large errors, which may also cause deformation of the welded frame
Moreover, it takes a lot of time to manually press and fix the side strips, and the production efficiency is low, so special positioning tooling is needed to improve production efficiency and product quality

Abstract

A welding and positioning tool for an air conditioner air return net frame comprises a rack, two clamping devices arranged on the rack and a first drive device driving one clamping device to be far away from or get close to the other clamping device, wherein each clamping device comprises a base, two corner clamping mechanisms arranged on the base and a second drive device driving one corner clamping mechanism to be far away from or get close to the other corner clamping mechanism; each corner clamping mechanism comprises a mounting plate, a side edge positioning mechanism fixed on the mounting plate and a top pressing mechanism fixed on the mounting plate; four corner clamping mechanisms can be reasonably distributed at four corners of the frame through horizontal movement of the clamping devices and longitudinal movement of the corner clamping mechanisms, the side edge positioning mechanisms and the top pressing mechanisms tightly press two side bars at the corners, and the 45-degree notches in the end parts of the side bars can be accurately matched and meet the welding requirement.

Description

technical field [0001] The invention relates to a positioning tool, in particular to a welding positioning tool for the frame of an air return air net of an air conditioner. Background technique [0002] Automobile air conditioner return air grid needs a frame for support and installation. The frame of automobile air conditioner return air grid is generally rectangular, which is welded by four side bars end to end. There is no special positioning tool for welding the frame of the return air net of the air conditioner at present, and the workers completely rely on the workers to press the side strips tightly and then weld them. Since the side strips may be deformed during processing or storage, causing the side strips to be twisted, it is difficult to align the cuts of adjacent side strips during welding, which makes the welded frame deformed, making it difficult to install . In addition, during welding, since it is artificially pressed and fixed, there are relatively large...
