Description

Technical Field

[0001] The utility model relates to the technical field of structural welding devices, in particular to a steel structure welding tool. 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 carried out in a variety of environments. No matter where it is, welding may bring danger to the operator, so appropriate protective measures must be taken during welding. The possible harm caused by welding to the human body includes burns, electric shock, vision damage, inhalation of toxic gases, excessive ultraviolet radiation, etc., and welding tooling is a set of flexible welding fixing, clamping and positioning fixtures used for welding various weldable materials.

[0003] For example, a steel structure welding positioning tool with announcement number CN111438484B includes a load-bearing plate, and limiting grooves are symmetrically provided on the top of the load-bearing plate. The inner cavities of the two limiting grooves are movably connected with movable plates, the bottoms of the two movable plates are fixedly connected with extension rods, the bottom ends of the two extension rods are fixedly connected with threaded rods, the bottom ends of the two threaded rods are movably connected with the bottoms of the inner walls of the two limiting grooves respectively, the outer walls of the two threaded rods and located below the load-bearing plate are threadedly connected with locking pieces, the bottom ends of the two threaded rods are fixedly connected with rotating blocks, the tops of the two movable plates are provided with positioning blocks, and the bottoms of the two positioning blocks are symmetrically provided with reset components.

[0004] The above-mentioned device utilizes the setting of the movable plate and the rotating block. By moving and rotating the rotating block, the movable plate is driven to disengage from the limiting groove and rotate a certain angle, and then re-enter the limiting groove to achieve the positioning work of steel structures in different directions, thereby improving the applicability of the positioning tooling for steel structure welding. However, the design of the limiting groove has different degrees of fixation on different steels. When it comes to curved steel, this fixing method is difficult to achieve complete fixation. Slippage may occur during welding, causing errors in industrial operations. Utility Model Content

[0012] Preferably, the outer surface of the retractable column is connected to the clamping end, and the inner surface of the clamping end is provided with a friction surface.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. Compared with other steel structure welding tools, this device can effectively clamp most steel materials through the clamp arms designed on both sides. The telescopic columns set at both ends of the clamp arms are used to control the tightening and relaxation of the clamp arms. The friction surface set on the contact surface of the clamp arms can effectively increase the friction between the steel structure and prevent slippage during welding operations, which may cause welding accidents or fail to meet welding standards.

[0015] 2.
