[0002] During the tire manufacturing process, some tires may have some defects in appearance. In order to ensure product quality, it is required that the tires be carefully inspected manually before they are put into storage to prevent defective tires from entering the market and causing losses to the company.

[0003] In order to improve production efficiency and reduce the labor intensity of workers, it is necessary to develop a device that can realize multi-directional rotation of tires on a platform to facilitate manual detailed inspection of defects inside and outside the tires. Utility Model Content

[0004] The purpose of the utility model is to solve the deficiencies of the above-mentioned technology and provide a lifting and rotating platform for tire appearance inspection.

[0005] To this end, the utility model provides a tire appearance inspection lifting and rotating platform, including a main frame, a linear guide rail fixedly connected to the side, and a lifting frame sliding on the linear guide rail through a guide rail slider; the lifting frame is connected to a servo cylinder through a joint bearing, and the bottom of the servo cylinder is fixedly connected to the main frame; a rotating shaft is also provided on the lifting frame, and a disc support is fixedly connected to the disc support; the rotating shaft is rotatably connected to the lifting frame through a tapered roller bearing, and the rotating shaft and the tapered roller bearing adopt an interference fit, and the tapered roller bearing is arranged to be thin at the top and thick at the bottom.

[0006] Furthermore, the tapered roller bearing is fixed in the bearing box by an upper bearing cover and a lower bearing cover. Both the upper bearing cover and the lower bearing cover are provided with flanges for adjusting the clearance between the inner and outer sleeves of the tapered roller bearing.

[0007] Furthermore, the bottom of the servo cylinder is fixedly connected to the main frame through an earring bracket.

[0008] Furthermore, the upper bearing cover, the lower bearing cover and the bearing box are all provided with mutually cooperating limiting structures for ensuring the stability of the upper bearing cover, the lower bearing cover and the bearing box after they are assembled.

[0009] The utility model provides a lifting and rotating platform for tire appearance inspection, which has the following beneficial effects:

[0010] The manual inspection of the finished tire appearance can be realized quickly, which can meet the use requirements of people of different heights and improve the comfort of workers. The matching structure of the tapered roller bearing makes the bearing rotate smoothly and the turntable rotates lightly, which makes it easier to inspect and rotate the tire on the turntable, reducing the labor intensity of the workers during operation.

[0015] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments to help understand the content of the present invention. The methods used in the present invention are all conventional methods unless otherwise specified; the raw materials and devices used are all conventional commercial products unless otherwise specified.

[0016] like Figure 1-3 As shown, the utility model provides a lifting and rotating platform for tire appearance inspection, including a main frame 13, a linear guide 11 fixedly connected to the side, and a lifting frame 8 slidingly cooperates with the linear guide 11 through a guide slider 12. The lifting frame 8 is connected to a servo cylinder 10 through a joint bearing 9, and the bottom of the servo cylinder 10 is fixedly connected to the main frame 13 through an earring bracket 14. By providing the joint bearing 9, the load capacity of the connection between the lifting frame 8 and the servo cylinder 10 can be improved, and the wear resistance is strong. The lifting frame 8 is also provided with a rotating shaft 3, and the top of the rotating shaft 3 is fixedly connected to a disc support 2, and the disc 1 is fixedly connected to the disc support 2.

[0017] like Figure 2As shown, the rotating shaft 3 is rotatably connected with the lifting frame 8 through the tapered roller bearing 5. The rotating shaft 3 and the tapered roller bearing 5 are interference fit, and the tapered roller bearing 5 is thin at the top and thick at the bottom. By setting the tapered roller bearing 5, it can withstand the axial and radial loads when the disc 1 rotates, and has a longer service life. The tapered roller bearing 5 is fixed in the bearing box 6 through the bearing upper pressure cover 4 and the bearing lower pressure cover 7. In order to ensure the processing error of the bearing box 6 on the lifting frame 8, the clearance between the inner and outer sleeves of the tapered roller bearing 5 is finally adjusted by the height of the flange 15 of the bearing upper pressure cover 4 and the bearing lower pressure cover 7 to ensure that the inner sleeve of the tapered roller bearing 5 and the shoulder of the rotating shaft 3 are matched without clearance, and at the same time, the clearance between the inner and outer sleeves of the tapered roller bearing 5 is appropriate, so that the disc 1 can rotate smoothly without blocking.

[0018] When in use, the staff first places the tire on the disc 1, and then starts the servo cylinder 10 according to their own height and working habits, so that the guide slider 12 moves along the linear guide 11, and adjusts the lifting frame 8 to a height suitable for themselves; finally, the staff manually rotates the disc 1 to conduct a comprehensive inspection of the tire appearance.

[0019] In the description of the present invention, it should be understood that the terms "left", "right", "up", "down", "top", "bottom", "front", "back", "inside", "outside", "back", "middle", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0020] However, what is described above is only a specific embodiment of the present invention and should not be used to limit the scope of implementation of the present invention. Therefore, the replacement of equivalent components, or equivalent changes and modifications made according to the scope of protection of the patent of the present invention should still fall within the scope covered by the claims of the present invention.
