Technical Field

[0001] This utility model belongs to the field of mechanical automation equipment, specifically relating to a tooling for detecting the centerness of the central tube of the inner tank of a liquid oxygen respirator. Background Technology

[0002] Liquid oxygen is oxygen in its liquid state and has important applications in medicine, high-altitude environments, and other gas industries. Specialized storage devices are required for the transportation and storage of liquid oxygen. Cryogenic liquid oxygen atmospheric pressure storage tanks are widely used in the liquid oxygen industry, serving as a container for holding liquid oxygen during transportation and storage. The central pipe of the liquid oxygen tank plays a crucial role in the central oxygen supply system, primarily storing liquid oxygen and ensuring efficient vaporization and transportation. The quality of its installation determines the overall quality of the liquid oxygen tank.

[0003] The centering accuracy of the central tube is one of the main indicators for evaluating its installation quality. However, there is currently no device specifically designed for testing the centering accuracy of the central tube of a liquid oxygen tank, which makes it impossible to guarantee the installation quality of the central tube. Utility Model Content

[0004] The purpose of this invention is to provide a tooling for detecting the centerness of the center tube of the inner tank of a liquid oxygen respirator, so as to solve the problem that the installation quality of the center tube cannot be guaranteed due to the lack of a detection device for the centerness of the center tube.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: This utility model relates to a fixture for detecting the centering of the inner tank center tube of a liquid oxygen respirator, which includes a base plate, an inner tank fixing seat, a slide rail, and a movable detection block; the inner tank fixing seat and the slide rail are both fixed on the upper surface of the base, and the inner tank fixing seat is located at the end of the slide rail; the movable detection block is slidably connected to the slide rail, and the movable detection block is provided with a detection hole corresponding to the center tube of the inner tank.

[0006] Preferably, the inner tank fixing seat includes a fixing base and a fixing block, the fixing block being disposed between the fixing base and the moving detection block, the fixing block being used to support the end cap of the inner tank, and the fixing block being used to support the cylinder of the tank.

[0007] Preferably, the fixed base and the movable detection block are each provided with a groove on their opposite sides that matches the outer contour of the end cap.

[0008] Preferably, the fixing block is provided with a U-shaped groove that matches the outer contour of the cylinder.

[0009] The groove and U-shaped groove design allows the inner tank fixing seat to fit completely against the inner tank, increasing the stability of the inner tank and avoiding detection errors caused by the inner tank shaking during the testing process.

[0010] Preferably, a limit shock absorber is provided at an end of the slide rail, which prevents the movable detection block from sliding out of the slide rail and provides buffering for the movable detection block.

[0011] Compared with the prior art, the technical solution provided by the present utility model has the following beneficial effects: The centrality detection tool for the central tube of the inner tank of a liquid oxygen respirator related to the present utility model comprises an inner tank fixing seat, a slide rail and a movable detection block, wherein the inner tank fixing seat is arranged at an end of the slide rail, the movable detection block is slidably connected with the slide rail, and a detection hole corresponding to the central tube of the inner tank is arranged on the movable detection block. The movable detection block is moved to fit it with the head of the inner tank, and it is observed whether the central tube passes through the detection hole. If the central tube passes through the detection hole, it is further observed whether the centrality of the central tube is within the tolerance range. If it is within the range, it is determined as qualified. The structure fills the gap in the detection of the centrality of the central tube, helps to improve the factory quality of liquid oxygen respirators, and has a simple structure.

[0014] To further understand the content of the present utility model, the present utility model is described in detail with reference to embodiments. The following embodiments are used to illustrate the present utility model, but not to limit the scope of the present utility model.

[0015] With reference to the accompanying Figure 1 and 2 shown, the present utility model relates to a centrality detection tool for the central tube of the inner tank of a liquid oxygen respirator, which comprises a base plate 1, an inner tank fixing seat, a slide rail 5 and a movable detection block 4. The movable detection block 4 is slidably connected with the slide rail 5, and a detection hole 6 corresponding to the central tube of the inner tank is arranged on the movable detection block 4.

[0016] The inner tank fixing seat and slide rail 5 are both fixed to the upper surface of the base 1, with the inner tank fixing seat located at the end of the slide rail 5. The inner tank fixing seat includes a fixed base 2 and a fixing block 3. The fixing block 3 is located between the fixed base 2 and the movable detection block 4. The fixing block 3 supports the end cap 10 of the inner tank and the cylindrical body 11 of the tank. The fixed base 2 and the movable detection block 4 each have a groove 7 on their opposite sides that matches the outer contour of the end cap 10. The fixing block 3 has a U-shaped groove 8 that matches the outer contour of the cylindrical body 11. The groove 7 and the U-shaped groove 8 ensure that the inner tank fixing seat fits perfectly with the inner tank, increasing the stability of the inner tank and preventing errors caused by the inner tank shaking during the detection process.

[0017] The end of the slide rail 5 is also provided with a limiting shock absorber 9. The limiting shock absorber 9 is made of cylinder, spring or piston, etc., which serves to prevent the moving detection block 4 from sliding out of the track 5 and to provide a buffer for the moving detection block 4.

[0018] See attached document Figure 3 As shown, during the inspection process, the inner can is placed on the inner can fixing base. Specifically, the bottom end cap of the inner can is placed into the groove 7 of the fixing base 2, and the cylinder 11 of the inner can is placed on the U-shaped groove 8 of the fixing block 3. Then, the moving detection block 4 is pushed to move along the slide rail 5 to one side of the inner can, so that the groove 7 of the moving detection block 4 fits against the upper end cap of the inner can. At this time, first observe whether the central tube can pass through the detection hole 6. If it cannot pass, it is judged as unqualified. If it passes, further observe whether the centerness of the central tube is within the tolerance range. If it is not within the tolerance range, it is also judged as unqualified. If it is within the tolerance range, it is judged as qualified.
