Technical Field
[0001] This utility model relates to the field of vacuum welding technology, and in particular to a material welding device in a vacuum environment. Background Technology
[0002] Special materials, such as high-purity metals, oxygen-sensitive alloys, and precision connections of electronic components, are severely compromised by impurities like oxygen, nitrogen, and moisture during atmospheric welding. Traditional welding methods, even with shielding gas, struggle to completely eliminate these issues. Therefore, welding equipment operating in a vacuum environment is crucial. Existing welding equipment generates toxic gases during welding, leading to high concentrations in confined spaces, which can harm the working environment. Furthermore, welding typically requires workers to move around the material, creating gaps in the weld and affecting its continuity. Additionally, cleaning and collecting weld slag on the worktable is difficult. Utility Model Content
[0003] The purpose of this invention is to provide a material welding device in a vacuum environment to solve the problems mentioned in the background art, such as the generation of toxic gases during welding, the high concentration of which poses a great hazard in a closed environment, the need for workers to weld around the material, the resulting welding gaps during personnel movement affecting the continuity of the welding, and the difficulty in cleaning and collecting welding slag that falls onto the worktable.
[0004] The purpose and effectiveness of this material welding device in a vacuum environment are achieved by the following specific technical means:
[0005] A material welding device for a vacuum environment, comprising a vacuum chamber; a flip-up door panel is hinged to the front side of the right side wall of the vacuum chamber, and transparent observation windows are fixedly installed on the front side of the flip-up door panel and the top of the vacuum chamber; two flip-up fixing buckles are rotatably connected to the upper and lower end faces and the front side of the left side wall of the vacuum chamber; a three-jaw clamp is rotatably connected to the middle of the right side wall of the vacuum chamber; and a sealing bottom cover is slidably engaged at the bottom of the vacuum chamber.

The three-jaw clamp 7 is fixed by rotating the knob 703, and the elastic ratchet 702 hinged at the bottom right end of the three-jaw clamp 7 engages in the tooth groove of the one-way toothed disc 102, thereby... During material welding, the rotation of the three-jaw clamp 7 is controlled to improve the convenience of circumferential welding. Then, an air inlet branch pipe 103 is connected to the right side of the rear wall of the vacuum chamber 1 to inject air into the vacuum chamber 1. An exhaust branch pipe 104 is connected to the bottom of the left side wall of the vacuum chamber 1 to discharge the toxic gases generated inside the vacuum chamber 1 due to welding. The exhaust branch pipe 104 is connected to an air purification device to avoid toxic gas pollution of the operating environment. An "L"-shaped welding torch hanger is connected to the inner rear wall and the inner left wall of the vacuum chamber 1 for convenient placement and use of the welding torch.
