Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of machining, especially the technical field of a welding automatic fixing tool. BACKGROUND

[0002] Welding, also known as fusion welding, is a manufacturing technique that uses high temperature or high pressure to join metal parts. The energy sources for welding include electric arc, laser, gas flame, electron beam, and ultrasonic wave. In the process of metal workpiece machining, welding is one of the most commonly used metal processing methods.

[0003] In the existing technology, welding is mainly completed by manual welding. Manual welding is performed by workers holding welding tools and melting solder under high-temperature electric arc to weld objects together. However, manual welding often has hidden dangers and may cause burns, electric shock, vision impairment, and inhalation of toxic gases to workers.

[0004] To solve the problems raised in the background art, for example, application number CN202120078907.5 discloses an automatic welding machine with dust removal and noise reduction function, which includes a main body, a fixed block is fixedly connected to the inner wall bottom of the main body, a connecting port is opened on the outer wall of one side of the main body, a soundproof board is arranged on the inner wall of one side of the main body, a load table is slidingly connected to the inner wall of the main body, the outer wall of the load table is slidingly connected to the inner wall of the soundproof board, the inside of the main body is kept sealed, the material of the main body is an acoustic material, the inside of the main body can be vacuum treated, and welding work is performed in a vacuum environment. Through the double effects of the designed vacuum working environment and the added soundproof board, the noise caused by welding is completely isolated, and the beneficial effect of noise reduction is achieved. However, the device still has the following defects:

[0005] The above device cannot effectively protect the workpiece during the workpiece welding process. The debris generated during the welding process of the workpiece splashes everywhere, which can easily pollute the surrounding environment. Moreover, the debris distributed around is difficult to clean up, and the high-temperature debris generated by welding can easily scald the skin of the surrounding workers.

[0006] To solve the problems raised in the above-mentioned technologies, for example, application No. CN202323368826.7 discloses a workbench for workpiece welding, which comprises a table body, support legs welded around the outer wall of the bottom of the table body, a fixing assembly arranged on the outer wall of the top of the table body, a cleaning assembly arranged on the outer wall of one side of the table body, and the fixing assembly and the cleaning assembly being matched with the table body. An installation groove is arranged on the outer wall of the top of the table body. The workpiece is welded. When welding, the electric telescopic rod drives the protection groove to rise to protect the table body, blocks the debris generated by the welding of the workpiece, and makes the debris fall on the table body, so as to prevent the debris from splashing and polluting the surrounding environment. At the same time, it is convenient to clean the debris after the workpiece is welded. However, the device still has the following defects:

[0007] Although the above-mentioned device can prevent the debris from splashing and polluting the surrounding environment, the positioning effect of the workpiece is not good, which leads to the position deviation of the workpiece in the welding process, thereby affecting the welding process.
