Description

Technical Field

[0001] This utility model relates to the field of oxygen cylinder processing technology, and more specifically, to a welding fixture for oxygen cylinder processing. Background Technology

[0002] Oxygen cylinders are high-pressure containers used for storing and transporting oxygen. They are generally made of alloy structural steel through hot stamping and pressing, and are cylindrical in shape. They are used in hospitals, emergency stations, and sanatoriums. Some oxygen cylinders require welding of two or more sections of cylindrical tubes during processing, which requires the use of tooling to fix the cylindrical tubes.

[0003] A search revealed that utility model patent CN220296198U discloses a welding fixture for oxygen cylinder processing, comprising a base, a clamping plate fixedly mounted on the upper surface of the base, a pressure plate provided on the upper surface of the clamping plate, a groove formed on the lower surface of the pressure plate, a clamping rod fixedly mounted on the inner top wall of the groove, the bottom of the clamping rod inserted into the upper surface of the clamping plate, a screw inserted into the pressure plate, the bottom of the screw penetrating the pressure plate and extending to the outside of the pressure plate and fixedly connected to the top of the clamping plate, and a nut threadedly connected to the surface of the screw. A slide rail is fixedly mounted on the upper surface of the base. This welding fixture for oxygen cylinder processing, by inserting the pressure plate onto the clamping plate, then inserting the clamping rod onto the clamping plate, and then using ball bearings to limit and support the clamping plate, facilitates positioning and welding operations, thus not affecting the normal use of the welding fixture during use and improving the efficiency of the fixture.

[0004] However, the aforementioned patents have the following shortcomings: they are not convenient for clamping round tubes of different outer diameters, and they are not convenient for driving the round tubes to be welded to rotate, requiring the welding torch to rotate, which affects the convenience of welding; moreover, welding produces odorous gases, affecting the surrounding environment. To address these issues, we propose a welding fixture for oxygen cylinder processing. Utility Model Content

[0038] In this embodiment, the stability of the hexagonal transmission column 31 in the hexagonal groove 17 during extension and retraction is ensured, while the stability of the transmission between the transmission tube 16 and the hexagonal transmission column 31 is also ensured.

[0039] For details, please refer to Figure 5 The outer side of the purification box 22 is hinged with a sealing door 26, and the side of the activated carbon plate 25 is respectively attached to the inner wall of the purification box 22 and the inner side of the sealing door 26.

[0040] In this embodiment, the activated carbon plate 25 inside the purification box 22 is replaced by opening the sealed door 26.

[0041] Working principle: In use, firstly, place the two round tubes to be welded on the two first support rollers 14 and the two second support rollers 12 respectively, and start the two electric telescopic rods 19 to drive the two extrusion rollers 21 to move downwards, so that the two extrusion rollers 21 limit the top of the two round tubes respectively. Then, start the brake motor 5 to drive the lead screw 4 to rotate. Through the threaded engagement between the lead screw 4 and the moving block 6, the moving block 6, the moving seat 8, the second support roller 12 and a round tube move, so that the ends of the two round tubes to be welded are in contact. At the same time, the hexagonal transmission column 31 extends and retracts in the hexagonal groove 17 on the transmission tube 16. Then, use the welding torch to weld the joint of the round tubes. At the same time, start the reduction motor 15 to drive one of the first support rollers 14 to rotate, using the first support roller 14 to extend and retract. The support roller 14 drives a transmission tube 16 to rotate, which in turn drives a second support roller 12 to rotate through the transmission between the hexagonal transmission column 31 and the hexagonal groove 17. The rotation of the second support roller 12 and the first support roller 14 drives the two welded round tubes to rotate synchronously, thereby fixing the position of the welding torch and welding the two round tubes. Finally, the vacuum pump 27 is started to draw air into the inner cavity of the purification box 22. The negative pressure in the inner cavity of the purification box 22 causes the damping telescopic hose 23 and the suction hood 24 to generate suction. The suction of the suction hood 24 draws the odor gas generated by welding into the inner cavity of the purification box 22. The activated carbon plate 25 adsorbs the odor in the gas. The adsorbed gas is discharged to the outside through the exhaust hose 28, ensuring the environment around the welding is clean.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
