Description

Technical Field

[0001] The utility model relates to the technical field of welding, in particular to a welding device which is convenient for limiting and fixing. 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. Welding equipment refers to the equipment required to implement the welding process. The main types of welding equipment include electric welders, flame welding equipment and other welding equipment.

[0003] At present, in life, the commonly used welding equipment is a welding gun and a connecting pipe that are movably mounted. Although the movable mounting is convenient for users to disassemble, the mounting of the welding gun and the connecting pipe may be unstable during the welding process, causing the connecting pipe and the welding gun to fall off, affecting work efficiency and having low safety performance. In addition, since ordinary welding equipment does not have a device to fix the connecting pipe, the connecting pipes may be entangled with each other during the welding process, thereby affecting the use of the welding gun.

[0004] Therefore, those skilled in the art provide a welding device that is convenient for limiting and fixing to solve the problems raised in the above background technology. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings existing in the prior art, and to propose a welding device that is easy to limit and fix. The device adds multiple limit devices and fixing devices.

When the limit device no longer squeezes the control block, the No. 2 telescopic rod is closed, so that the No. 1 groove is no longer in a sealed state. When the limit device moves to the outside of the welding table, the No. 2 moving block can be controlled to move, and then the connecting pipe is placed between the two limit blocks to form a positioning device. The same is true when not in use. After the operation is completed, the welding gun can be directly placed in the inside of the placement box. In addition, the fixing device makes the connection between the connecting pipe and the welding gun more stable. Because a plurality of No. 2 spring groups and No. 3 limit blocks are fixedly arranged inside the fixing device, the connection between the connecting pipe and the welding gun is more stable when the connection is placed inside the fixing device, thereby reducing the possibility of the welding gun and the connecting pipe falling off.
