Technical Field

[0001] This utility model relates to the field of steel pipe testing technology, specifically a dual-end positioning seamless steel pipe pressure testing device for new energy vehicles. Background Technology

[0002] Seamless steel pipes are made by piercing a whole round steel bar and have no weld seams on the surface. According to the production method, seamless steel pipes can be divided into hot-rolled seamless steel pipes, cold-rolled seamless steel pipes, cold-drawn seamless steel pipes, extruded seamless steel pipes, jacking pipes, etc. Seamless steel pipes have a wide range of uses and are mainly used as pipelines for transporting fluids or structural parts.

[0003] According to a utility model patent with Chinese patent application number 202323315687.1, a steel pipe compressive strength testing device can prevent the fragments from splashing outwards and injuring people during the stamping process caused by the steel pipe breaking. However, this steel pipe compressive strength testing device is inconvenient to fix and limit pipes of different diameters during use, and can only be fixed by pipe sleeves, which makes the fixation and limiting of the steel pipe unstable. Therefore, it is necessary to propose a double-end positioning type seamless steel pipe compressive strength testing device for new energy vehicles to solve the above-mentioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a dual-end positioning seamless steel pipe compression testing device for new energy vehicles, which has the advantages of being able to limit and fix steel pipes of different diameters, thus solving the problem of inconvenience in limiting and fixing steel pipes of different diameters in the prior art.

[0005] To achieve the above-mentioned purpose of limiting and fixing steel pipes of different diameters, this utility model provides the following technical solution: a double-end positioning seamless steel pipe pressure resistance testing device for new energy vehicles, including a fixed frame, a first positioning component and a second positioning component are movably installed inside the fixed frame, and a fixed plate is fixedly installed on the right side of the fixed frame; The second positioning component includes a second threaded rotating rod. The second threaded rotating rod is movably installed inside the fixed frame. Two sets of positioning blocks are threadedly connected to the outer surface of the second threaded rotating rod. A first positioning plate and a second positioning plate are respectively provided on one side of the two sets of positioning blocks. Rubber pads are provided on the corresponding sides of the first positioning plate and the second positioning plate. A turntable is provided on the top of the second threaded rotating rod.

[0006] Furthermore, the first positioning component includes a first threaded rotating rod, which is movably mounted inside the fixing frame. A threaded block is threadedly connected to the outer surface of the first threaded rotating rod, and a blocking plate is provided on the top of the threaded block.

[0007] Furthermore, a knob is provided at the top of the first threaded rod, and two sets of both the first positioning component and the second positioning component are provided.

[0008] Furthermore, a through groove is provided on the side of the fixing frame, and a steel pipe body passes through the inside of the through groove.

[0009] Furthermore, a control panel is provided on the front of the mounting bracket, and a pressure testing component is provided on the bottom of the mounting bracket.

[0010] Furthermore, a lifting structure is movably installed inside the fixed plate, and a magnetic leakage detector is provided on the left side of the lifting structure.

[0011] Furthermore, a limiting cylinder is fixedly installed on the top of the fixing frame, and the second threaded rotating rod is movably installed inside the limiting cylinder.

[0012] Furthermore, the steel pipe body is positioned between the first positioning plate and the second positioning plate.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects: This dual-end positioning seamless steel pipe pressure testing equipment for new energy vehicles, by setting up a first positioning component, allows the first threaded rod to rotate when the knob is turned during use. The fixed frame limits the movement of the baffle plate, allowing the threaded block to move on the outer surface of the first threaded rod. This simultaneously moves the two sets of baffle plates closer or further apart, achieving clamping, fixing, or releasing of the steel pipe body. It can limit and fix the outer wall of the steel pipe body, improving the stability of the pressure testing component for the steel pipe body.

[0014] This dual-end positioning seamless steel pipe pressure testing equipment for new energy vehicles, by setting up a second positioning component, allows for the rotation of a turntable during use. The turntable rotates the second threaded rod, which in turn moves the positioning blocks up and down on the external threads. The two sets of positioning blocks move the first and second positioning plates closer or further apart. As the first and second positioning plates move closer together, they can position both ends of the steel pipe body, further improving the stability of the steel pipe body and ultimately enhancing the accuracy of the pressure testing component in testing the steel pipe body.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-3 The dual-end positioning type seamless steel pipe pressure testing equipment for new energy vehicles in this embodiment includes a fixed frame 1, a first positioning component 4 and a second positioning component 6 are movably installed inside the fixed frame 1, and a fixed plate 7 is fixedly installed on the right side of the fixed frame 1. The second positioning component 6 includes a second threaded rotating rod 601. The second threaded rotating rod 601 is movably installed inside the fixing frame 1. Two sets of positioning blocks 603 are threadedly connected to the outer surface of the second threaded rotating rod 601. A first positioning plate 604 and a second positioning plate 606 are respectively provided on one side of the two sets of positioning blocks 603. Rubber pads 605 are provided on the corresponding sides of the first positioning plate 604 and the second positioning plate 606. A turntable 602 is provided on the top of the second threaded rotating rod 601.

[0019] In the implementation of the case, by setting the first positioning component 4, when in use, by rotating the knob 401, the knob 401 will drive the first threaded rod 402 to rotate, and through the limiting effect of the fixing frame 1 on the blocking plate 404, the threaded block 403 can move at the outer surface of the first threaded rod 402, thereby synchronously driving the two sets of blocking plates 404 to move closer or further away from each other, realizing the clamping and fixing or loosening of the steel pipe body 11, and limiting and fixing the outer wall of the steel pipe body 11, improving the stability of the pressure testing component 10 in testing the steel pipe body 11.

[0020] In the implementation of the case, by setting up the second positioning component 6, when in use, by rotating the turntable 602, the turntable 602 will drive the second threaded rotating rod 601 to rotate, and the second threaded rotating rod 601 will drive the positioning block 603 to move up and down on the external thread. The two sets of positioning blocks 603 will drive the first positioning plate 604 and the second positioning plate 606 to move away from or towards each other. When the first positioning plate 604 and the second positioning plate 605 move closer, they can position the two ends of the steel pipe body 11, further improving the stability of the steel pipe body 11, and ultimately improving the testing accuracy of the pressure testing component 10 on the steel pipe body 11.

[0021] In the implementation of the case, the lifting structure 8 can drive the magnetic flux leakage detector to rise and fall, match the steel pipe body 11 of different diameters, and detect the steel pipe body 11 through the magnetic flux leakage detector; after magnetizing the steel pipe body 11, the metal loss and dent deformation are detected by the change of the magnetic flux leakage field; the dent will cause magnetic field leakage, which is manifested as a single peak bulge in the radial signal and a dent in the cosine curve of the axial signal.

[0022] In the case implementation, the pressure of the pressure testing component 10 is controlled by the control panel 2 to facilitate the determination of the pressure borne by the steel pipe body 11.

[0023] When implementing this procedure, please follow these steps: 1) First, insert the steel pipe body 11 through the through groove 3; 2) Then the steel pipe body 11 is positioned by the first positioning component 4 and the second positioning component 6; 3) Then, the steel pipe body 11 is subjected to pressure test by the pressure test assembly 10; 4) Finally, use the magnetic flux leakage detector 9 to check whether the steel pipe body 11 is damaged.

[0024] In summary, this dual-positioning seamless steel pipe pressure testing equipment for new energy vehicles, by setting up a first positioning component 4, allows the first threaded rotating rod 402 to rotate when the knob 401 is turned during use. The fixed frame 1 limits the movement of the blocking plate 404, enabling the threaded block 403 to move at the outer surface of the first threaded rotating rod 402. This simultaneously moves the two sets of blocking plates 404 closer together or further apart, achieving clamping, fixing, or releasing of the steel pipe body 11. This limits and fixes the outer wall of the steel pipe body 11, improving the stability of the pressure testing component 10's testing of the steel pipe body 11.

[0025] Furthermore, by setting the second positioning component 6, during use, rotating the turntable 602 will drive the second threaded rotating rod 601 to rotate, and the second threaded rotating rod 601 will drive the positioning block 603 to move up and down on the external thread. The two sets of positioning blocks 603 will drive the first positioning plate 604 and the second positioning plate 606 to move away from or closer to each other. During the process of the first positioning plate 604 and the second positioning plate 605 approaching each other, the two ends of the steel pipe body 11 can be positioned, further improving the stability of the steel pipe body 11, and ultimately improving the testing accuracy of the pressure testing component 10 on the steel pipe body 11.
