Laser welding mechanism for metal support

Abstract

The invention discloses a laser welding mechanism for a metal support, and belongs to the field of support welding. The laser welding mechanism comprises a base table plate; four carrying shaft seats are arranged at the top end of the base table plate; the four carrying shaft seats are respectively arranged at four corners of the base table plate; every two carrying shaft seats form a group; one side of each carrying shaft seat is provided with a carrying column; annular grooves are formed on the side wall of the carrying column, and the ends of the annular grooves are in butt joint; a carrying motor is fixedly installed on the side wall of one carrying shaft seat; the side walls of carrying rotary discs are fixedly connected with the carrying columns; the two carrying rotary discs are connected through a carrying belt; pressing arms are further installed on one sides of the carrying shaft seats; the end of each pressing arm is inserted into the inner side of the carrying shaft seat; the pressing arms are rotatably connected with the carrying shaft seats; the other end of each pressing arm is provided with a pressing wheel; the middle of the pressing arm is provided with a drooping line; and the bottom end of the drooping line is provided with a lead block. Automatic welding can be achieved conveniently.

Description

technical field [0001] The invention relates to the field of bracket processing, in particular to a laser welding mechanism for metal brackets. Background technique [0002] With the development of industrial technology, modern mechanical processing has become more and more perfect, and a lot of brackets need to be used when mechanical assembly or processing is added. Since the current mechanical processing is mass-produced and produced, large factories Batches of metal brackets are needed. In the sheet metal processing industry, the brackets used are made of square tubes and round tubes; [0003] When assembling the metal bracket, it is necessary to open a round hole on the square tube, and then insert a metal round tube into the round hole on the square tube to weld the metal round tube to the square tube. The previous welding methods include plasma welding or electric current. Welding, but these welding methods will grow very high arcs, and these arcs will also cause met...

Problems solved by technology

[0003] When the metal bracket is assembled, it is necessary to open a round hole on the square tube, and then insert a metal round tube into the round hole on the square tube, and weld the metal round tube to the square tube. The previous welding methods include plasma welding or electric current. Welding, but these welding methods will grow very high arcs, and these arcs will also cause metal debris to splash, which also pollutes the working environment to a certain extent. Using laser slow welding will not produce debris splashes, and when welding It is also necessary to manually position the steel pipe, and the accuracy of manual positioning is not high enough
