Description

Technical Field

[0001] This application relates to the field of machining technology, and in particular to a welding equipment. Background Technology

[0002] With the continuous development of steel processing technology, welding is increasingly being adopted in production due to its fast forming speed and stable structure. However, when products need to be welded, it is often necessary to fix the products and at the same time ensure that the products do not deform after welding. To effectively solve the above problems, the best way is to promote welding equipment with a high degree of mechanization and automation in welding production.

[0003] To improve the welding production speed of the 7-shaped structural welded plate, welding equipment was applied to its welding production process. The 7-shaped structural welded plate includes a horizontal welded plate, a vertical welded plate, and side welded plates arranged opposite each other. The weld treatment process includes manual argon arc welding and laser welding. Specifically, the horizontal welded plate, vertical welded plate, and side welded plates are pre-positioned by manual argon arc welding. Then, the 7-shaped structural welded plate is clamped by the welding equipment and laser welding is performed. Due to the difference in the operation gestures of each person, the dimensional accuracy error of the weld of the 7-shaped structural welded plate pre-positioned by manual argon arc welding is large and the weld quality is unstable. It is not possible to guarantee the consistency and reliability of the repeated positioning of the weld, resulting in a low first-pass yield of the 7-shaped structural welded plate.

The upper long-side clamping plate moves vertically downwards, clamping the first side of the horizontal welding plate 2 and then releasing pressure. The upper short-side driving component in the upper short-side clamping device drives the upper short-side clamping plate to move vertically downwards, clamping the second side of the horizontal welding plate 2 and then releasing pressure. The front long-side clamping device 1101 operates and maintains pressure, and the rear driving component in the rear clamping device 1102 drives the rear clamping plate to move along the first direction, cooperating with the front clamping device 1101 to clamp the vertical welding plate 3 on the horizontal welding plate 2 and then maintain pressure.
