[0026] In order to solve the technical problems in the background art, as shown in Figs. 1-2 The present application provides a technical solution: a stainless steel pipe precision inspection rack, characterized by:

[0027] The fixed table 1 is circular in structure, and is located at the bottom center of the whole fine inspection frame, serving as the basic support component of the whole device and providing a stable mounting platform for other components. The center of the fixed table 1 is provided with a bearing 2, which is connected with the center rod 10 to realize the rotating function of the center rod 10. In addition, the bottom of the fixed table 1 is annularly provided with a plurality of rotating shafts 12, one end of each rotating shaft 12 being connected with a suction cup 13 for fixing the fine inspection frame, and the fine inspection frame is fixed on the workbench or other support surface through the suction cup 13. The upper portion of the fixed table 1 is uniformly distributed with a plurality of positioning blocks 3, which are annularly arranged, uniformly and equidistantly distributed at the edge of the fixed table 1. The main function of the positioning block 3 is to fix and support the tray 4, ensuring that the tray 4 remains stable during use. The tray 4 is coaxially arranged with the fixed table 1, and the shape and size are designed according to the specifications of the stainless steel pipes to be detected, usually circular, with sufficient strength and rigidity to bear the weight of the pipes. The tray 4 is provided with grooves 5 for accommodating the pipes, and the shape and size of the grooves 5 are matched with the outer diameter of the pipes to ensure that the pipes can be stably placed in the grooves 5. In addition, the circumference of the tray 4 is uniformly provided with a plurality of limiting grooves 6, which are one-to-one corresponding with the positioning blocks 3 on the fixed table 1, and the shape and size of the limiting grooves 6 are matched with the limiting blocks 7, which are fixed in the limiting grooves 6 through the pin shaft 8. The two ends of the connecting rod 9 can be respectively provided with connecting holes or connecting heads for connecting with the positioning blocks 3 and the limiting blocks 7; or the connecting rod 9 can be inserted into the positioning blocks 3 and the limiting blocks 7 through the insertion holes provided on the positioning blocks 3 and the limiting blocks 7. The main function of the connecting rod 9 is to connect the positioning blocks 3 and the limiting blocks 7 to form a stable support structure, connecting the tray 4 with the fixed table 1 together to ensure that the tray 4 remains stable during detection, preventing the pipes from being displaced or damaged due to the shaking of the tray 4. The center rod 10 is a vertical rod, and the center rod 10 passes through the center of the tray 4 and is connected with the bearing 2. The side wall of the center rod 10 is annularly provided with a plurality of clamping mechanisms 11, and the number of the clamping mechanisms 11 is the same as that of the grooves 5, and they are one-to-one corresponding. The main function of the center rod 10 is to realize the rotating function through the bearing 2, driving the clamping mechanisms 11 to rotate, thereby realizing the clamping and rotating operation of the pipes, facilitating the comprehensive detection of the pipes by the detection personnel. The rotating shaft 12 is annularly arranged at the bottom of the fixed table 1, and a plurality of rotating shafts 12 are uniformly distributed, and the suction cup 13 is installed at one end of the rotating shaft 12, which can be of the vacuum type or other types with sufficient adsorption force, and the number and distribution position are determined according to the actual fixing requirements. The main function of the rotating shaft 12 and the suction cup 13 is to fix the whole fine inspection frame on the workbench or other support surface, ensuring that the fine inspection frame does not move or shake during use, and providing a stable support environment for the detection work. The auxiliary lamp 14 is arranged on the rotating shaft 12 and can rotate around the rotating shaft 12. The auxiliary lamp 14 is arranged on the rotating shaft 12, and the lamp body part is connected with the rotating shaft 12 through a suitable fixing device, and the lamp head part is designed with an adjustable angle structure, such as a bendable lamp pole, so as to adjust the illumination angle as needed during detection.The auxiliary lamp 14 can adopt LED lamp or other suitable lighting device, has enough brightness and good lighting effect, can provide uniform and soft light, facilitates the detection personnel to observe the pipe surface. The rotation angle of the auxiliary lamp 14 is 360 degrees, and the light direction can be adjusted according to the detection needs.

[0028] It should be noted that the positioning block 3 is uniformly and equidistantly distributed on the fixed table 1 in the form of a ring, the limiting block 7 is installed in the limiting groove 6 of the tray 4 and connected with the limiting groove 6 through the pin shaft 8. The ring-shaped position where the positioning block 3 is located is on the upper surface of the fixed table 1, and the ring-shaped diameter is relatively large, so that the positioning block 3 can effectively support and position the outer edge of the tray 4, ensuring that the tray 4 remains stable during the detection process. The ring-shaped position where the limiting block 7 is located is at the side wall of the tray 4, and the ring-shaped diameter is relatively small. Since the ring-shaped diameter where the positioning block 3 is located is large, it supports the tray 4 on the outside of the tray 4, effectively disperses the weight and external force received by the tray 4, and improves the stability of the tray 4. At the same time, the positioning block 3 and the limiting block 7 are connected through the connecting rod 9 to form a stable support structure, ensuring that the tray 4 does not shake or tilt during the detection process, and ensuring the accuracy and reliability of the detection.

[0029] It should be noted that the end of the center rod (10) is provided with a handle 15, which is usually in the form of a column or a handle structure, and the shape conforms to the ergonomic design, facilitating the operator to hold and operate. The surface of the handle 15 is provided with an anti-slip layer, which can be made of rubber, silicone or other materials with anti-slip performance, and is fixedly connected with the handle 15 by means of pasting, wrapping or one-piece forming, and has uneven texture or granular structure on the surface to increase the friction and prevent the hands from slipping during operation. The main function of the handle 15 is to provide a convenient and comfortable holding position for the operator, so that the operator can rotate the center rod 10 by hand during operation, thereby driving the clamping mechanism 11 to rotate and realize the detection of the pipe in different clamping mechanisms 11. When rotating, the pipe needs to be lifted so that it does not fall into the groove 5 to prevent the rotation of the center rod 10.

[0030] It should be noted that the groove 5 is arranged on the tray 4, and the shape is semispherical, that is, the surface of the tray 4 is inwardly recessed to form a semispherical space. The semispherical structure makes the groove 5 have a large volume and a deep depth, which can better accommodate the stainless steel pipe. The semispherical groove 5 can uniformly distribute the weight of the pipe, reduce the contact stress between the pipe and the tray 4, and reduce the risk of deformation or damage of the pipe during detection. At the same time, the semispherical groove 5 can adapt to pipes of different diameters.

[0031] It is worth noting that the clamping mechanism 11 includes a first clamping piece 16, a second clamping piece 17 and a first spring 18. The first clamping piece 16 and the second clamping piece 17 are both in the shape of a piece, and their shape and size are designed according to the diameter of the pipe to be detected and the clamping requirements. Both have a semicircular clamping end 19 for accommodating the pipe. The clamping end 19 is semicircular, which can closely fit the outer surface of the pipe and provide stable clamping force. The first clamping piece 16 and the second clamping piece 17 are connected by a hinged connection, and the hinge part usually uses a pin or a rivet connector, so that the two can rotate relative to each other, realizing the action of clamping and releasing the pipe. The first spring 18 is a tension spring or a compression spring, and its two ends are connected to the first clamping piece 16 and the second clamping piece 17 respectively. The connection method can use hooks, welding or other reliable connection methods. The first spring 18 provides elastic force to keep the first clamping piece 16 and the second clamping piece 17 in a natural state with a certain clamping force, ensuring that the pipe does not loosen or fall off during detection. The first clamping piece 16 has a horizontal end that is perpendicular to the clamping end 19 of the first clamping piece 16, forming an "L" shape. The side wall of the center rod 10 is provided with a notch that fits the horizontal end, and the shape and size of the notch match the horizontal end, ensuring that the horizontal end is stably fitted in the notch, achieving reliable connection between the first clamping piece 16 and the center rod 10.

[0032] It is worth noting that the guide surface 20 is arranged on the clamping end 19 and is located on the first clamping piece 16 and the second clamping piece 17 respectively. Its shape is a gradually converging horn, that is, it gradually narrows from the clamping end 19 to the near end, forming a structure similar to a horn mouth. The larger side of the horn mouth formed by the guide surface 20 faces the insertion direction of the pipe.

[0033] It is worth noting that the second spring 21 is located between the fixed table 1 and the tray 4, and its position should be considered in terms of the force bearing of the spring and the support effect on the tray 4. Usually, the second spring 21 is evenly distributed between the fixed table 1 and the tray 4 to ensure that the tray 4 can be evenly supported in all directions. The two ends of the spring are connected to the fixed table 1 and the tray 4 respectively, and the connection position should be selected at the edge or near the edge of the fixed table 1 and the tray 4 to facilitate the installation and force transmission of the spring. The main function of the second spring 21 is to provide elastic support force to keep the tray 4 stable during detection. When the tray 4 is subjected to external forces such as the weight of the pipe and the impact of the detection equipment, the second spring 21 can generate elastic force to offset part of the external force and reduce the shaking and vibration of the tray 4, thereby improving the accuracy and reliability of the detection.

[0034] It is worth mentioning that the number of rotating shafts 12 is at least 3, which is to ensure that the fine inspection frame has sufficient stability and carrying capacity during use. The three rotating shafts 12 are evenly distributed at the bottom of the fixed table 1, forming a stable triangular support structure, which can effectively resist various interference forces from the outside and ensure the smooth operation of the fine inspection frame.

[0035] While the embodiments of the application have been illustrated and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the spirit and scope of the application, which is defined by the appended claims and their equivalents.
