DETAILED DESCRIPTION

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1-4 As shown, a wheel rim quality inspection auxiliary device includes a base 1, a lifting platform 4 above the base 1, a guide mechanism 3 between the lifting platform 4 and the base 1, a limiting mechanism 5 installed at the lower part of the lifting platform 4, a rotating shaft 8 rotatably mounted within the limiting mechanism 5, the limiting mechanism 5 restricting the rotating shaft 8 from moving axially within the limiting mechanism 5, a screw 9 connected to the lower part of the rotating shaft 8, and a mounting base 2 below the limiting mechanism 5, the mounting base 2 having a threaded hole 10 inside, and the lower part of the screw 9 being threaded... Connected to the threaded hole 10, the lower part of the lifting platform 4 has a cavity 12. The upper end of the rotating shaft 8 extends into the cavity 12 and is connected to the driven bevel gear 11. A rotating seat 6 is installed on the side of the lifting platform 4. A drive shaft 14 is rotatably arranged in the rotating seat 6. The inner end of the drive shaft 14 extends into the cavity 12 and is connected to the drive bevel gear 15. The drive bevel gear 15 meshes with the driven bevel gear 11. The drive shaft 14 is rotatably connected to the lifting platform 4. The outer end of the drive shaft 14 passes through the rotating seat 6 and is connected to the turntable 7. When loading or unloading the rim, the lifting platform 4 is adjusted to a lower height to facilitate removing the rim from the lifting platform 4 or placing the rim on the lifting platform 4.

[0021] During rim inspection, the turntable 7 drives the drive shaft 14 to rotate. The drive bevel gear 15 on the drive shaft 14 drives the rotating shaft 8 to rotate through the meshing driven bevel gear 11. The rotating shaft 8 then drives the screw 9 to rotate within the threaded hole 10, causing the rotating shaft 8 to rise. Due to the limitation of the rotating shaft 8 by the limiting mechanism 5, the lifting platform 4 rises along with the rotating shaft 8, raising the rim to a suitable height, making it convenient for workers to inspect the spoke holes on the outer circumference of the rim.

[0022] The upper part of the lifting platform 4 has several mounting slots 29, which are arranged radially along the length of the lifting platform 4. These mounting slots 29 are evenly distributed in a circumferential shape on the lifting platform 4. Support wheels 30 are rotatably mounted within each mounting slot 29, and are arranged along the length of the mounting slot 29. The length of the support wheels 30 is greater than the wall thickness of the rim, and the position of the support wheels 30 is set according to the diameter of the rim, allowing the rim to be placed on each support wheel 30 for support. This allows workers to more easily rotate the rim when inspecting the spoke holes on its outer circumference.

[0023] Further, the limiting mechanism 5 comprises a mounting cylinder 17 connected to the bottom of the lifting platform 4, the inner wall of the mounting cylinder 17 is connected to a limiting ring one 18, the lower part of the mounting cylinder 17 is provided with a fixing cylinder 19, the inner wall of the fixing cylinder 19 is connected to a limiting ring two 20, the outer periphery of the rotating shaft 8 is connected to a supporting ring 21, the supporting ring 21 is located between the limiting ring one 18 and the limiting ring two 20, the outer diameter of the supporting ring 21 is greater than the inner diameter of the limiting ring one 18 and the limiting ring two 20, the upper end of the supporting ring 21 abuts against the lower end of the limiting ring one 18, and the lower end of the supporting ring 21 abuts against the upper end of the limiting ring two 20, and the supporting ring 21 can rotate between the limiting ring one 18 and the limiting ring two 20. The axial movement of the supporting ring 21 is limited by the limiting ring one 18 and the limiting ring two 20, so that the lifting platform 4 rises and falls synchronously with the rotating shaft 8.

[0024] The outer diameter of the driven bevel gear 11 is smaller than the inner diameter of the limiting ring one 18, so that the driven bevel gear 11 can pass through the limiting ring one 18 and extend into the cavity 12.

[0025] Further, the rotating disc 7 is rotatably connected with a handle 27. The rotating disc 7 is provided with a containing groove 26 on the outer side, the handle 27 is rotatably connected in the containing groove 26, and the containing groove 26 is provided with clamping blocks 28 on the side walls located on the left and right sides of the handle 27. In use, the handle 27 is turned out of the containing groove 26, so that the handle 27 is perpendicular to the rotating disc 7, and the rotating disc 7 is conveniently rotated. When not in use, the handle 27 is turned into the containing groove 26, and is fixed by the clamping blocks 28 on the left and right sides.

[0026] The connection between the handle 27 and the containing groove 26 is located on the side of the rotating disc 7 away from the center, and the handle 27 is conveniently turned out of the containing groove 26 to drive the rotating disc 7 to rotate.

[0027] Further, the guide mechanism 3 comprises a guide cylinder 22 mounted on the upper part of the base 1 and a connecting rod 24 mounted on the lower part of the lifting platform 4, the guide cylinder 22 is provided with a guide cavity 23, and the lower end of the connecting rod 24 extends into the guide cavity 23 and is connected with a guide disc 25. The cross section of the guide cavity 23 is circular, and the outer periphery of the guide disc 25 is arranged in close contact with the side wall of the guide cavity 23. The guide disc 25 and the guide cylinder 22 form a limiting part, so that the lifting platform 4 can only move in the vertical direction, and the lifting platform 4 is prevented from deviating when rising and falling.

[0028] Further, the lifting platform 4 is provided with a plurality of movable blocks 31, the movable blocks 31 are connected with wheel frames 32 on the outer side, and the wheel frames 32 are rotatably provided with rollers 33. When the wheel rim is placed, the rollers 33 are located on the inner side of the wheel rim. The lifting platform 4 is provided with a sliding seat 13, the movable blocks 31 are slidably arranged in the sliding seat 13, and the inner end of the movable block 31 and the sliding seat 13 are connected with a spring 16.

[0029] When the wheel rim is placed on the lifting platform 4, the movable block 31 can move towards the center of the lifting platform 4, so that the roller 33 does not hinder the placement of the wheel rim. After the wheel rim is placed, the roller 33 can abut against the inner wall of the wheel rim. The roller 33 guides and limits the wheel rim during rotation, so that the wheel rim does not deviate during rotation.

[0030] The above only describes the preferred embodiments of the present application, and the protection scope of the present application is not limited to the above-mentioned embodiments. Any technical solution falling within the concept of the present application belongs to the protection scope of the present application. It should be noted that, for ordinary skilled persons in the technical field, some improvements and refinements without departing from the principles of the present application are also considered to be within the protection scope of the present application.
