Description

Technical Field

[0001] The utility model relates to the field of welding equipment, and more specifically to laser straight seam automatic welding equipment. 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 be dangerous to the operator, so appropriate protective measures must be taken when welding. Possible injuries to the human body caused by welding include burns, electric shock, visual impairment, inhalation of toxic gases, excessive ultraviolet radiation, etc.

[0003] For example, announcement number CN113798767B discloses a straight seam laser welding positioning fixture and straight seam laser welding. Among them, a straight seam laser welding positioning fixture includes: a mounting plate, a positioning assembly and a clamping assembly, the positioning assembly includes a long strip lining, an elastic top support and a centering reference plate; the supporting surface of the lining is provided with a gap along the length direction, the elastic top support is arranged in the gap and abuts against the opposite side walls of the gap; the centering reference plate is arranged in the gap and is slidably connected to the elastic top support; the clamping assembly includes a pressing block and a driving device, the pressing block is connected to the driving end of the driving device; the positioning assembly is located below the mounting plate and connected to the mounting plate, and the clamping assembly is located above the mounting plate and connected to the mounting plate. The problems of the difficulty in centering and adjusting the straight seam laser welding positioning fixture, the difficulty in controlling the centering positioning accuracy and assembly accuracy, the insufficient degree of automation, the high repetitive labor and the low versatility are solved.

[0004] It can be seen from the above-mentioned public scheme that the current welding equipment mostly limits the workpiece to be welded to the left and right, and does not have the function of squeezing the welding straight seams against each other so that the straight seams can be automatically connected and the straight seams can be smaller, thereby affecting the welding effect. At the same time, the welding device is mostly arranged at the upper end of the workpiece to be welded, and is supported by the support beam. When the welding device moves, it will generate direct surface contact friction with the support beam, which can easily cause friction damage to the contact surface, and also increase the friction resistance, making it difficult for the welding device to move.
