Description

Technical Field

[0001] The invention relates to the technical field of sheet metal welding, and in particular to a precision positioning welding device. Background Art

[0002] Welding, also known as fusion, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. There are many sources of energy for modern welding, including gas flame, arc, laser, electron beam, friction and ultrasound. In addition to being used in factories, welding can also be performed in a variety of environments, such as outdoors, underwater and in space. No matter where it is, welding may bring danger to the operator, so appropriate protective measures must be taken during welding. The possible injuries to the human body caused by welding include burns, electric shock, vision damage, inhalation of toxic gases, excessive ultraviolet radiation, etc.

[0003] The patent application with application number CN202111667344.4 discloses a precise positioning and welding device for flat steel for steel grating.

A plurality of mutually parallel transverse platforms are slidably connected to the support platform, and a plurality of limit blocks arranged in the vertical direction are provided on both sides of the transverse platform. The limit blocks are arranged along the length direction of the transverse platform, and the spacing between adjacent limit blocks is the same.

[0004] When the above-mentioned equipment is used to weld cylindrical raw materials, it is impossible to effectively clamp the sheet metal, which can easily cause the fixed sheet metal to shift, resulting in the welding gun being unable to accurately align with the welding port. At the same time, the moving trajectory of the welding gun cannot move well along the welding line, resulting in the welding effect being less than expected. Summary of the invention

[0005] The object of the present invention is to provide a precise positioning welding device to solve the problems raised in the above background technology.

After the baffle moves downward, the placement components on both sides of the equipment will be driven to move toward the center through the connecting rod, so that the fitting part of the sheet metal after the movement is completed can be just under the welding gun, thereby improving the accuracy of welding.
