Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-7 , an embodiment provided by the present invention: a shaft product detection device, including a bracket 1, a motor 3, a movable frame 7 and a pneumatic rod 29. The right end of the outer wall of the bracket 1 is fixedly connected with a fixed frame 2, and a motor 3 is installed on the front side of the outer wall of the fixed frame 2. A movable frame 7 is arranged at the upper end of the bracket 1. Movable rings 13 are attached to the front and back surfaces of the outer wall of the movable frame 7. Detectors 28 are evenly arranged on the inner wall surface of the movable ring 13. A pneumatic rod 29 is arranged below the bracket 1;

[0023] Furthermore, a chute 4 is opened in the middle of the interior of the fixed frame 2, and a first screw rod 5 is connected to the middle of the inner wall of the chute 4 through a bearing. The outer end of the outer wall of the first screw rod 5 is connected to the output end of the outer wall of the motor 3. A first nut 6 is threadedly connected to the outer wall surface of the first screw rod 5. The outer end of the outer wall of the first nut 6 is fixed to the outer wall surface of the movable frame 7. This structure can change the horizontal position of the movable frame 7 by remotely controlling the motor 3, and the motor 3 is a mature existing technology and will not be elaborated here.

[0024] Furthermore, a first roller 8 is installed on the right side of the inner wall of the movable frame 7, and first bevel gears 9 are connected to the upper and lower sides of the outer wall of the first roller 8. A second bevel gear 11 meshes with the outer wall surface of the first bevel gear 9, and a toothed disc 12 is fixedly connected to the outer wall surface of the second bevel gear 11. A rotating shaft 10 is fixedly connected to the middle of the interior of both the toothed disc 12 and the second bevel gear 11. Teeth 14 meshing with the outer wall surface of the toothed disc 12 are evenly arranged on the inner wall surface of the movable ring 13. Guide blocks 16 are fixedly connected to the front and back surfaces of the outer wall of the movable frame 7, and a guide groove 15 adapted to the guide block 16 is opened in the interior of the movable ring 13. When the first roller 8 fits and moves along the shaft product, it will mesh with the toothed disc 12 through the outer wall, thereby driving the toothed disc 12 to rotate, and then the movable ring 13 adapted to the toothed disc 12 can be driven to rotate.

[0025] Furthermore, a card slot 17 is provided on the left side of the movable frame 7, and a second screw rod 18 is inserted in the middle of the inner wall of the card slot 17. A first limit groove 19 is provided on the outer wall surface of the second screw rod 18. A first limit block 20 is fixedly connected to the end of the inner wall of the card slot 17. The outer wall surface of the first limit block 20 is adapted to the inner wall of the first limit groove 19. A second screw sleeve 21 is threadedly connected to the middle of the outer wall of the second screw rod 18. A second roller 22 is installed at the end of the second screw rod 18. A third bevel gear 23 is fixedly connected to the outer wall surface of the second screw sleeve 21. A fourth bevel gear 25 meshes with the outer wall surface of the third bevel gear 23. A first rotating rod 24 is fixedly connected to the middle of the outer wall of the fourth bevel gear 25. A fifth bevel gear 27 meshes with the outer wall surface of the middle fourth bevel gear 25. A second rotating rod 26 is fixedly connected to the middle of the outer wall of the fifth bevel gear 27. Two sets of second rollers 22 are provided in this structure. By rotating the first rotating rod 24, the two sets of second rollers 22 can be horizontally displaced to clamp and fit the shaft product in the middle of the movable frame 7, so that the outer wall surfaces of the second rollers 22 and the first rollers 8 are both in contact with the outer wall surface of the shaft product.

[0026] Furthermore, the outer wall surfaces of the two sets of movable rings 13 are adapted to the outer wall surface of the movable frame 7, and rubber pads are provided on the outer wall surfaces of the first rollers 8 and the second rollers 22. This structure can avoid damaging the outer wall of the shaft product during clamping when in use.

[0027] Preferably, a chuck 30 is rotatably connected to the end of the outer wall of the pneumatic rod 29, and the outer wall surface of the chuck 30 abuts against the end of the outer wall of the shaft product. This structure can rotate the chuck 30, thus facilitating the removal or insertion of the shaft product into or from the movable frame 7.

[0028] Working principle: When in use, the front chuck 30 is moved and opened by the pneumatic rod 29. The shaft product is passed through the middle of the inner walls of the movable frame 7 and the movable ring 13. Then, the front end of the pneumatic rod 29 is used to squeeze and stabilize the shaft product. At this time, the clamping stability inside the movable frame 7 can be adjusted. By rotating the end of the fifth bevel gear 27, the first rotating rod 24 and the fourth bevel gear 25 at the end are driven to rotate by the second rotating rod 26. After that, the fourth bevel gear 25 drives the engaged third bevel gear 23 to rotate. At this time, the third bevel gear 23 will drive the second screw sleeve 21 to rotate, so that the second screw sleeve 21 performs a threaded movement with the second screw rod 18. At this time, the second screw rod 18 will perform a lateral position movement under the limitation of the first limit block 20, thereby pushing out the two second rollers 22, so that the two second rollers 22 squeeze and clamp the shaft product in the middle, and at the same time, the outer wall of the shaft product is made to fit and clamp with the outer wall surface of the first roller 8. After the clamping is stable, the motor 3 can be started by remote control to drive the first screw rod 5 at its output end to rotate, so that the first screw rod 5 performs a threaded movement with the first screw sleeve 6, thereby causing the first screw sleeve 6 to perform a lateral position movement and driving the movable frame 7 to move. At this time, the movable frame 7 moves on the outer wall surface of the shaft product, and the first roller 8 and the second roller 22 will rotate, so that the first bevel gear 9 on the outer wall of the first roller 8 rotates and drives the second bevel gear 11 engaged with the first bevel gear 9. And the second bevel gear 11 will simultaneously drive the toothed disc 12 to rotate on the outer wall of the rotating shaft 10. When the toothed disc 12 rotates, it will be adapted to the teeth 14 on the inner wall of the movable ring 13. And at this time, the movable ring 13 will rotate. And through the adaptation of the guide groove 15 and the guide block 16, the movable ring 13 will only rotate on the outer wall surface of the movable frame 7. Thus, when the movable ring 13 rotates, the detector 28 always takes pictures and detects the shaft product in the middle. And the detector 28 is a prior art, and its basic principle is to check the defects and straightness of the shaft body through the cooperation of the infrared and vision modules. Its specific structure and principle will not be elaborated here. At the same time, the two movable rings 13 rotate relative to each other, and the outer wall surface of the shaft product can be detected without dead angles. The above is the whole working principle of the present utility model.

[0029] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-mentioned exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, in any aspect, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, it is intended to embrace all changes within the meaning and scope of the equivalent elements of the claims in the present utility model. Any reference signs in the claims should not be regarded as limiting the claimed rights.
