Antiskid welding clamp

Abstract

The invention discloses an antiskid welding clamp which comprises an upper connecting rod and a lower connecting rod. A fixing plate is welded to one side of the bottom of the upper connecting rod, and a first extrusion pad for fixing a circular pipe is arranged at the bottom of the fixing plate. A groove is formed in the part, on the top of the fixing plate, of the upper connecting rod, a spiralrotating rod is connected inside the groove in a threaded mode, a pushing rod is welded to the bottom of the spiral rotating rod, and the bottom of the groove communicates with a rubber pad at the bottom of the first extrusion pad through a communication pipe. In the antiskid welding clamp, the communication pipe is internally filled with hydraulic oil, the pushing rod can be driven to move downwards by rotating the spiral rotating rod, the hydraulic oil can be extruded to the rubber pad accordingly, then the rubber pad swells, accordingly the surface of the first extrusion pad is uneven, in this way, the circular pipe can be sufficiently fixed through the first extrusion pad, and the situation that the surface of a first extrusion pad skids to affect fixation of the circular pipe is prevented.

Description

technical field [0001] The invention relates to the technical field of welding fixtures, in particular to an anti-slip welding fixture. Background technique [0002] Welding, also known as welding or welding, is a manufacturing process and technology that uses heat, high temperature or high pressure to join metal or other thermoplastic materials such as plastics. Welding achieves the purpose of joining through the following three ways: 1. Fusion welding. 2. Pressure welding. 3. Brazing. There are many sources of energy for modern welding, including gas flames, electric arcs, lasers, electron beams, friction, and ultrasound. In addition to its use in factories, welding can also be performed in a variety of environments, such as in the field, underwater and in space. Welding, wherever it occurs, can pose a hazard to the operator, so proper precautions must be taken when welding. Possible injuries caused by welding to the human body include burns, electric shock, visual im...

Problems solved by technology

[0003] The round tube has a circular structure, so it is usually easy to slip when clamping the round tube. However, most of the existing round tube clamping devices clamp it by squeezing and fixing it. If there is a clamping device If sliding occurs, there will be loopholes in the clamping of the round tube, which will affect the welding effect of the round tube
