Description
Technical Field
[0001] The utility model relates to the technical field of pipe roundness detection, in particular to a fixing device for pipe roundness detection. Background Art
[0002] Due to the complex environment in which the pipeline is located, it is easy for the pipeline to bend under the action of external loads during use, which will destroy the stability of the pipeline and cause accidents such as leakage. Therefore, after the pipe processing is completed, it is often necessary to perform multiple tests on the rolled pipe, and out-of-roundness is one of them. Out-of-roundness is usually determined by testing the outside and inside of the pipe to determine whether the pipe is qualified. If it is unqualified, it needs to be reworked, and most of the roundness detection of the pipe is done manually. Manual detection is done using the human eye. The human eye will undergo visual changes with the ambient light angle and light intensity, resulting in visual illusions and large errors. A small number of mechanical inspections are often performed because the clamp fixing method is used, which often leads to poor pipe fixing effect, easy sliding or offset, and the overall pipe cannot be guaranteed to be on a horizontal plane, resulting in detection errors. Utility Model Content
[0003] The purpose of the utility model is to provide a fixing device for detecting the roundness of a pipe in view of the shortcomings of the prior art, so as to solve the problem that a small part of the mechanical detection proposed in the above background technology often uses a clamp fixing method, resulting in poor fixing effect of the pipe, easy sliding or deviation, and the whole cannot be kept on a horizontal plane, thereby causing detection errors.

[0011] By adopting the above technical solution, the threaded barrel is provided to achieve through-thread adjustment.
[0012] Preferably, a through-hole plate is fixed on one side of the connecting plate, and a spring rod is fixed inside the through-hole plate, and one end of the spring rod is fixedly connected to a T-shaped rod with a magnet on one side.

[0019] (1) This case sets up: an adjustable clamping and fixing structure, thereby solving the problem that a small number of mechanical inspections often use clamp fixing methods, resulting in poor pipe fixing effects, easy sliding or offset, and the whole cannot be kept on a horizontal plane, resulting in inspection errors. When the pipe needs to be fixed, the operator passes the pipe through the through-hole frame, and then the operator turns the handwheel threaded rod to drive the connecting plate to move. During the force movement of the connecting plate, the through-hole plate is driven to move synchronously. When the through-hole plate is close to the pipe, the pipe is squeezed by the T-bar and the spring bar.

[0030] The above scheme further has mounting frames 106 fixed on both sides of the base plate 101, and guide wheels 107 fixed on the mounting frames 106, and an adjusting cylinder 108 fixed on one side of the mounting frame 106, and a connecting rope 109 is fixed to the output end of the adjusting cylinder 108, and one end of the connecting rope 109 is wound and fixed with the rubber plate 1010, there is one group of connecting ropes 109, and the connecting rope 109 and the rubber plate 1010 are connected in a "U" structure. When one group of the above components is provided, it not only reflects the synchronous driving adjustability of the above components, but also reflects the winding and fixing of the above components on the rubber plate 1010, and when the connecting rope 109 and the rubber plate 1010 are connected in a "U" structure, the axial symmetry of the above components and the practical adjustability of the connection setting are simultaneously reflected.
[0031] like Figure 3 , Figure 4 and Figure 5 As shown, an adjustment clamping and fixing structure 2 is fixed on the base structure 1, and the adjustment clamping and fixing structure 2 includes a through hole frame 201, and the overall shape of the through hole frame 201 is a rectangular structure. When the overall shape of the above-mentioned parts is a rectangular structure, it not only reflects the internal and external installation connectivity of the above-mentioned parts, but also reflects the force-driven adjustability of the above-mentioned parts. When the overall shape of the above-mentioned parts is a rectangular structure, the overall aesthetics of the above-mentioned parts and the axial and longitudinal axis symmetry are also reflected. A threaded barrel 202 is fixed through the inside of the through hole frame 201, and a handwheel threaded rod 203 is threadedly connected to the inside of the threaded barrel 202, and one end of the handwheel threaded rod 203 is fixedly connected to the connecting plate 204 through a bearing seat.
