[0001] The utility model relates to the technical field of wheel hub detection, in particular to a clamping mechanism for X-ray detection of wheel hubs. Background Technique

[0002] The wheel hub is an important component connecting the brake drum, the wheel disc and the half shaft. The safety of the wheel hub directly affects the safety of the vehicle. During the use of the vehicle, the wheel hub will be worn for a long time. Wheel hubs with poor quality are very likely to have a greater impact on the safety of the vehicle. Therefore, in the production of wheel hubs, the detection of the safety performance of the wheel hubs is essential. X-ray detection of wheel hubs is an important method for detecting the safety performance of wheel hubs.

[0003] The existing technology for X-ray detection of wheel hubs includes using an X-ray machine and a conveyor belt connected thereto, and using the conveyor belt to convey and clamp the wheel hub for detection. When the wheel hub is put into the X-ray machine for conveying and detecting without being clamped in time, it may affect the detection of the wheel hub, because if the wheel hub is not clamped when moving on the conveyor belt, it may roll or shift, resulting in unclear or inaccurate X-ray detection images. Therefore, a clamping mechanism for X-ray detection of wheel hubs is proposed to solve the above problems. Content of the Utility Model

A return spring is movably sleeved outside the adjusting rod, and both ends of the return spring are respectively connected to the opposite sides of the placing plate and the fixing plate for pushing the placing plate back to its original position. A clamping assembly is arranged on the lower surface of the fixing plate for clamping the edge of the wheel hub;

[0007] The clamping assembly includes four wire tubes, all of the four wire tubes are fixed to the lower surface of the fixing plate. Four sliding openings are formed in the upper surface of the fixing plate. Sliding blocks are respectively and slidably arranged inside the four sliding openings. Clamping columns are respectively fixed to the tops of the four sliding blocks. Tension ropes are respectively and slidably arranged inside the four wire tubes. One end of each tension rope is connected to the outside of the corresponding sliding block, and the other end of the tension rope is connected to the bottom end of the adjusting rod for pulling the sliding block to move along with the adjusting rod.

[0008] Further, the height of the support frame is greater than the length of the adjusting rod to provide sufficient movement space.

[0009] Further, pulling holes for the four tension ropes to slide are respectively formed in the outer sides of the guiding tubes, and pulleys are arranged on the inner walls of the upper and lower sides of each pulling hole to enable the tension ropes to slide smoothly.

[0010] Further, the diameter of the adjusting rod is equal to the aperture of the guiding tube to guide the adjusting rod to move along the path and prevent the placing tray from tilting.

[0011] Further, the clamping column is in the shape of a tapered barrel with a wider upper part and a narrower lower part to facilitate the subsequent removal of the wheel hub.

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Embodiment 1: Please refer to Figures 1 to 4 , a clamping mechanism for hub X-ray detection in this embodiment includes a clamping mechanism 2 arranged outside the X-ray equipment body 1.

[0022] Embodiment 2: Please refer to Figures 2 to 4 , on the basis of Embodiment 1, the clamping mechanism 2 in this embodiment includes a connecting plate 21 and a support frame 22. The connecting plate 21 is arranged outside the X-ray equipment body 1, the support frame 22 is connected to the upper surface of the connecting plate 21, a fixed plate 23 is arranged on the upper surface of the support frame 22, a connecting hole is opened in the middle of the upper surface of the fixed plate 23, and a guide tube 24 is arranged inside the connecting hole. An adjusting rod 25 is slidably arranged inside the guide tube 24, and the top of the adjusting rod 25 is fixed with a placing plate 26 for centering and placing the hub. The operator places the hub on the placing plate 26, and the gravity of the hub causes the placing plate 26 and the connected adjusting rod 25 to move downward along the guide tube 24. A return spring 29 is movably sleeved outside the adjusting rod 25, and both ends of the return spring 29 are respectively connected to the opposite sides of the placing plate 26 and the fixed plate 23 for pushing the placing plate 26 back to its original position. A clamping assembly 27 is arranged on the lower surface of the fixed plate 23 for edge clamping of the hub. When the detection is completed or re-clamping is required, the return spring 29 pushes the placing plate 26 and the adjusting rod 25 back to the initial position to prepare for the next clamping.

[0023] The clamping assembly 27 includes four wire pipes 271. The four wire pipes 271 are all fixed to the lower surface of the fixing plate 23. Four sliding openings 272 are formed in the upper surface of the fixing plate 23. Sliding blocks 273 are respectively and slidably arranged inside the four sliding openings 272. Clamping columns 274 are respectively fixed to the tops of the four sliding blocks 273. Tractive ropes 275 are respectively and slidably arranged inside the four wire pipes 271. The movement of the adjusting rod 25 drives the lower end of one end of the tractive rope 275 to move downward, thereby driving the other end of the tractive rope 275, and driving the connected sliding block 273 to move synchronously along the inside of the sliding opening 272. One end of the tractive rope 275 is connected to the outside of the sliding block 273, and the other end of the tractive rope 275 is connected to the bottom end of the adjusting rod 25, so as to drive the sliding block 273 to move along with the adjusting rod 25. The movement of the sliding block 273 drives the clamping column 274 to contact the edge of the hub, realizing preliminary clamping. When the clamping mechanism 2 moves into the equipment along with the conveyor belt in the equipment body for X-ray detection, during the X-ray equipment detection process, the clamped hub is detected, and the detection result is analyzed by the operator or the automatic system.

[0024] In this embodiment, the height of the support frame 22 is greater than the length of the adjusting rod 25, so as to provide sufficient movement space. Tractive holes for the four tractive ropes 275 to slide are respectively formed in the outer side of the guide pipe 24, and pulleys 28 are arranged on the inner walls of the upper and lower sides of each tractive hole, so as to enable the tractive ropes 275 to slide smoothly.

[0025] In this embodiment, the diameter of the adjusting rod 25 is equal to the aperture of the guide pipe 24, so as to guide the adjusting rod 25 to move along the path to prevent the placement tray 26 from tilting. The clamping column 274 is in the shape of a frustum of a cone with a wider upper part and a narrower lower part, so as to facilitate the subsequent removal of the hub. Sheaths are arranged on the outer sides of the four clamping columns 274, so as to protect the surface of the clamped hub. After the detection is completed, the conveyor belt drives the clamping mechanism 2 to continue to move and encounters a direction change, especially when moving downward, the center of gravity of the hub is reversed. The force generated by the reversal of the center of gravity of the hub is combined with the frustum shape design of the clamping column 274, so that the clamping column 274 expands outward under certain conditions, thereby realizing automatic loosening of the hub and facilitating separation.

[0026] The working principle of the above embodiment is as follows:

[0027] The operator places the hub on the placement plate 26. The gravitational force of the hub causes the placement plate 26 and the connected adjusting rod 25 to move downward along the guide tube 24. The movement of the adjusting rod 25 drives the other end of the traction rope 275 through the downward movement of one end of the traction rope 275, driving the connected sliding block 273 to move synchronously inside the sliding opening 272. The movement of the sliding block 273 drives the clamping column 274 to contact the edge of the hub, achieving preliminary clamping. When the clamping mechanism 2 moves into the device with the conveyor belt in the device body for X-ray detection, during the X-ray equipment detection process, the clamped hub is detected, and the operator or the automatic system analyzes the detection results. After the detection is completed, the conveyor belt drives the clamping mechanism 2 to continue moving and encounters a change in direction, especially when moving downward, the center of gravity of the hub flips. The force generated by the flip of the hub's center of gravity, combined with the conical shape design of the clamping column 274, causes the clamping column 274 to expand outward under certain conditions, thus realizing automatic release of the hub for easy separation. When the detection is completed or re-clamping is required, the return spring 29 pushes the placement plate 26 and the adjusting rod 25 back to the initial position to prepare for the next clamping.
