Description

Technical Field

[0002] Angle steel towers are mostly used in power projects. In order to support the installation of cables, angle steel towers are large in size. When making angle steel towers, the angle steel tower rods are placed on the welding tool, and the angle steel tower rods are welded into blocks, and then the blocks are combined to form an angle steel tower. The angle steel tower welding tool is used to fix the angle steel tower rods to facilitate the operation of the staff.

[0003] The existing angle steel tower welding fixture still has certain shortcomings when in use. First, the angle steel tower welding fixture is not convenient for fixing angle steel tower rods of different volumes, and is not convenient for welding the angle steel tower rods. In order to solve the above problems, reference can be made to an angle steel tower welding fixture disclosed in the prior art (application number CN201921144423.5, Chinese patent application date 2019-07-19). The welding fixture is connected to the angle steel tower by a second connecting vertical rod, a telescopic rod, a third connecting vertical rod and a second limiting rod. The second connecting vertical rod is connected to the third connecting vertical rod by a telescopic rod, which is convenient for The size of the tower rod adjusts the limiting range of the two groups of second limiting rods, which is convenient for fixing angle steel tower rods of different volumes; you can also refer to the prior art (Chinese patent application number CN202420813083.5, application date 2024-04-19) disclosed a positioning fixture for welding angle steel towers. The positioning fixture for welding angle steel towers, through the setting of the clamping assembly, places the two steel plates on the clamping grooves on the sides of the left turn plate and the right turn plate respectively, rotates the clamping plate so that the clamping plate fits the side of the steel plate, and then, twists the limiting rod to rotate through the bearing, and the limiting rod angle The change will make it clamped outside the limiting hole on the side of the splint, so that the splint pressurizes and fixes the steel plate to the side of the clamping groove, thereby achieving the effect of firmly clamping the steel plate, avoiding shaking during welding and causing welding deformation, which affects the overall firmness of the angle steel tower; finally, reference can be made to the double-limb angle steel tower cross plate welding positioning fixture disclosed in the prior art (application number CN202220735964.0, application date 2022-03-30 Chinese patent), which is provided by setting a cross slot on the table and four locations at the four ends of the cross slot and extending along the end relative to the cross slot. An extension portion is provided extending in the extension direction, and a sliding seat with a positioning groove is provided on the extension portion. When processing the cross plate, the cross groove can first complete the preliminary limiting of the cross plate to be processed, and then the sliding seat on the extension portion is adjusted by sliding so that the positioning groove on the sliding seat can be aligned with the cross plate to be processed, and the positioning is completed so that the cross plate has a fixed position and angle, and then the welding operation can be started. If the table top and the base are set to rotate together, the table top can be rotated after the welding is completed on one side, and the welding can be continued without moving, thereby facilitating the production and processing of the cross plate as a whole.

[0004] Although the above device can achieve the limited processing of objects, there are certain shortcomings in its use.
