Description

Technical Field

[0001] This utility model relates to the field of steel pipe processing technology, specifically to a steel pipe electric welding fixture. Background Technology

[0002] Steel pipes have a hollow cross-section, with a length much greater than their diameter or circumference. They are classified by cross-sectional shape into circular, square, rectangular, and irregularly shaped steel pipes; and by material into carbon structural steel pipes, low-alloy structural steel pipes, alloy steel pipes, and composite steel pipes. Welding fixtures are required for welding during the processing of steel pipes.

[0003] Traditional welding fixtures have certain shortcomings in use. The fumes produced during welding are pungent and pollute the air, reducing the environmental friendliness of the welding fixtures. At the same time, sparks are generated during welding, which can damage the skin or clothing if they fly into the human body, reducing the protective effect of the welding fixtures. Therefore, we have proposed a steel pipe welding fixture. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0018] For examples, please refer to Figures 1-4 This utility model provides a technical solution: A steel pipe welding fixture includes a base plate 1, a fixing plate 3 fixedly connected to the surface of the base plate 1, a vertical plate 11 fixedly connected to the top of the base plate 1, a limiting plate 12 slidably connected inside the vertical plate 11, a protective box 4 fixedly connected to the side of the limiting plate 12, a groove 20 opened in the fixing plate 3, the groove 20 being opposite to the protective box 4, a through hole 8 opened in the protective box 4, a transparent plate 7 fixedly connected to the surface of the protective box 4, a cylinder 9 installed on the top of the base plate 1, the bottom of the cylinder 9 being fixedly connected to a top plate 6, a purification box 10 fixedly connected to the top of the top plate 6, an air pump 16 installed at the bottom of the purification box 10, an air inlet pipe 17 fixedly connected to the bottom of the air pump 16, and the air inlet pipe 17 extending into the protective box 4.

[0019] In this embodiment, as Figure 1 and Figure 2 As shown, the top of the air pump 16 extends into the purification chamber 10. A suction plate 18 is fixedly connected to the inner wall of the purification chamber 10. Activated carbon balls 19 are adsorbed and connected to the surface of the suction plate 18. A cover plate 13 abuts against the top of the purification chamber 10. A pull ring 14 is fixedly connected to the top of the cover plate 13. An air outlet pipe 15 is fixedly connected to the top of the cover plate 13. The air outlet pipe 15 communicates with the purification chamber 10. A control plate 5 is fixedly connected to the surface of the base plate 1. A first clamping plate 22 is fixedly connected to the surface of the fixing plate 3. A second clamping plate 24 is provided on the top of the first clamping plate 22.

[0020] The welding fumes can be pumped into the purification chamber 10 by the air pump 16, and then the fumes are adsorbed and purified by the activated carbon balls 19. The purified fumes are then discharged through the exhaust pipe 15, which prevents the fumes from drifting directly into the air and causing air pollution, thus improving the environmental friendliness of the welding equipment during use.

[0021] In this embodiment, as Figure 3 and Figure 4 As shown, a steel pipe 23 abuts between the first clamping plate 22 and the second clamping plate 24. A fastening bolt 25 is threaded between the first clamping plate 22 and the second clamping plate 24. An electric welding ring 21 is sleeved on the outside of the steel pipe 23. The steel pipe 23 is placed on the surface of the first clamping plate 22, and then the second clamping plate 24 is placed on top of the first clamping plate 22. The fastening bolt 25 is rotated to fix the first clamping plate 22 and the second clamping plate 24 together, which can limit the position of the steel pipe 23. At this time, the connection of the steel pipe 23 is located inside the electric welding ring 21. A support seat 2 is fixedly connected to the bottom of the base plate 1. The bottom of the support seat 2 is provided with anti-slip texture. The support seat 2 is made of stainless steel. Multiple through holes 8 are provided.

[0022] The protective box 4 can be moved downwards by the cylinder 9, so that the protective box 4 and the fixed plate 3 are brought together, thus preventing sparks from flying into the human body during welding and causing injury, and improving the protective performance of the welding fixture during use.

[0023] The working process of this utility model is as follows: When the steel pipe welding fixture designed in this scheme is in operation, the steel pipe 23 is placed on the surface of the first clamping plate 22, and then the second clamping plate 24 is placed on top of the first clamping plate 22. The fastening bolt 25 is rotated to fix the first clamping plate 22 and the second clamping plate 24 together, which can limit the position of the steel pipe 23. At this time, the connection of the steel pipe 23 is located inside the welding ring 21. Then, under the action of the cylinder 9, the protective box 4 is moved downward, so that the protective box 4 and the fixing plate 3 abut together. Then, under the action of the control plate 5, the welding ring 21 is made to work, and the steel pipe 23 can be welded. When welding produces fumes, the fumes are drawn into the purification box 10 through the air inlet pipe 17 by the air pump 16. The fumes are adsorbed and purified by the activated carbon balls 19, and then discharged through the air outlet pipe 15, thus completing the welding work of the steel pipe 23.
