Description

Technical Field

[0001] The present invention relates to the technical field of welding devices, and particularly relates to a multi-angle welding device for stainless steel electric control cabinet cabinets. Background Art

[0002] Automation equipment has now been widely used in various industries. Electric control cabinets are an indispensable part of automation equipment. Electric control cabinets are usually welded by multiple groups of metal plates. Before welding, it is necessary to assemble the metal plates that make up the electric control cabinet. After assembly, the electric control cabinet box body is placed on a carrier, and then the welded equipment is used to weld the assembled components of the electric control cabinet together.

[0003] For example, in the patent application No. CN202022588218.7, there is a welding device for an electric control cabinet cabinet body. The cabinet body main body is placed in a card slot, and the working table is rotated by a power device to adjust the welding direction of the cabinet body. Then, a welding gun is driven by a robotic arm to weld the cabinet body. The overall operation is simple and highly flexible. At the same time, the welding fumes generated during welding are sucked into a treatment box by a blower cooperating with a suction hood, and harmful substances are removed by a filter screen and adsorbed by an activated carbon adsorption plate, reducing the pollution of welding fumes, and it has strong practicability; it includes a base, a bottom column, a working table, a card slot and a welding gun; it also includes a bracket, a motor, a lead screw, a sliding seat, a robotic arm, a power device, a rotating shaft, a bottom frame, a treatment box, a blower, an exhaust duct, a filter screen, an activated carbon adsorption plate, a suction duct and a suction hood. The sliding seat is screwed in the middle of the lead screw, the robotic arm is arranged on the right part of the sliding seat, and the welding gun is arranged on the right part of the robotic arm.

[0004] However, for the existing electric control cabinet welding equipment, its welding structure is imperfect. When welding the electric control cabinet vertically, it is necessary to use the welding equipment to weld each weld one by one. This welding method has low efficiency and cannot meet the use requirements of large-scale welding processing. Moreover, the existing electric control cabinet welding equipment lacks a structure for rapid positioning. When welding some precise positions, it is necessary for workers to calibrate the fixed position of the electric control cabinet on the carrier so that it is convenient for the welding equipment to find the starting point of welding. However, this method of manually calibrating the fixed position of the electric control cabinet is very troublesome and not suitable for large-scale processing. Summary of the Invention

[0015] In a possible implementation, a first U-shaped seat is fixedly connected to the two ball nuts. The first U-shaped seat is connected to a rotating rod through a rotating mechanism. The other end of the rotating rod is connected to a second U-shaped seat through a rotating mechanism. The two second U-shaped seats are fixedly connected to a lifting block.

[0016] In a possible implementation, the lifting block moves up and down along a lifting groove. Sliders are provided on both sides of the lifting block, and the sliders move up and down along a limiting groove.

[0017] In a possible implementation, welding devices are provided on the opposite sides of the two lifting blocks.

[0018] Beneficial effects:

[0019] After the fixing mechanism in the present invention fixes the cabinet body, the moving frame drives the welding device to perform vertical welding on the cabinet body.

[0020] In the present invention, when the servo motor is turned on, it drives the bidirectional lead screw to rotate, driving the ball nuts outside the bidirectional lead screw to move towards each other. Furthermore, the first U-shaped seats on both sides move towards each other.
