Description

Technical Field

[0001] This utility model belongs to the technical field of tire grinding devices, and in particular relates to a grinding device for the inner wall of automobile tires. Background Technology

[0002] Tires are round, elastic rubber products that roll on the ground and are usually made of wear-resistant rubber materials. They are mounted on metal rims. In order to repair or retread tires, it is usually necessary to use a tire inner wall grinding device to grind the inner wall of the tire and perform post-processing to increase the service life of the tire.

[0003] Currently, most tire inner wall polishing devices are used in a way that traditional tire polishing involves manual hand tools to polish and repair the inside of the tire. However, in this process, the repairman needs to manually squeeze the tool to polish the inner wall of the tire. If the squeezing force is too light, the polishing effect will be poor. If the squeezing force is too large, it will cause over-polishing, resulting in uneven thickness of the inner wall of the tire, which will affect the service life of the tire. Utility Model Content

[0004] The purpose of this invention is to provide a device for grinding the inner wall of automobile tires, which solves the existing problems.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a grinding device for the inner wall of automobile tires, including a fixed frame and a tire body, as well as grinding parts. The fixed frame has a fixed column on its inner side wall, and a connecting frame is fixedly installed on the outer wall of the fixed column. Two rotating shafts are rotatably installed on the inner wall of the connecting frame. Gear 1 is rotatably installed on the outer wall of each of the two rotating shafts. A force-bearing frame is fixedly installed on the outer wall of the two gear 1s, and gear 2 is fixedly installed on the outer wall of the force-bearing frame. The outer wall of the fixed column is provided with a limiting groove, the inner wall of the limiting groove is slidably provided with a toothed column, the free end of the fixed column is fixedly provided with an electric telescopic rod, and the output end of the electric telescopic rod and the toothed column are provided with a mounting block together; The toothed column is meshed with one of the two gears.

[0006] Furthermore, the inner wall of the connecting frame has toothed grooves at both ends on one side wall; Gear 3 and a fixing ring are fixedly installed on both sides of the outer wall of the rotating shaft, and a torsion spring is fixedly installed between gear 3 and gear 1. A spring is fitted on the outer wall of the rotating shaft, and the spring is fixedly connected to the fixed ring. The spring is located between the fixed ring and the inner wall of the connecting frame. The gear three is engaged with the tooth groove.

[0007] Furthermore, the grinding element is fixedly connected to the toothed column; The grinding component includes a motor fixedly mounted on the upper end face of the tooth column, and a grinding head is fixedly connected to the output end of the motor.

[0008] Furthermore, two support frames are symmetrically arranged on the lower end face of the fixing frame; A support block is fixedly installed on the upper end face of the fixed frame, and a cylinder is fixedly installed on the upper end face of the support block. The output end of the cylinder is connected to an anti-slip block. A controller is fixedly installed on one side wall of the mounting bracket.

[0009] Furthermore, the two gears are respectively engaged with the gear post.

[0010] Furthermore, both of the aforementioned rotating shafts can slide on the inner wall of the connecting frame.

[0011] Furthermore, the tire body is located between the two support frames and the anti-slip block, and is fitted onto the grinding head.

[0012] This utility model has the following beneficial effects: This invention uses the output end of a cylinder to drive the mounting block upwards. With the assistance of a limiting groove, the gear column drives the grinding part upwards to grind the tire. Simultaneously, the teeth on the outer wall of the gear column mesh with two gears. During the upward movement of the gear column, the two gears rotate in opposite directions, causing the force-bearing frame and gear three to flip downwards. When gear three meshes with the gear column, it automatically stops pressing on the inner wall of the tire, locking the gear column. This allows control over the grinding thickness, ensuring that the pressing force during grinding is just right.

[0013] This utility model, through the cooperation between the fixed ring and the spring, causes the gear three to separate from the tooth groove by squeezing the first gear at one end of the spring, and can rotate the shaft. This allows for the adjustment of the angle of rotation of the force frame and the second gear around the corresponding shaft, thereby flexibly controlling the thickness of the tire inner wall grinding, thus improving practicality and flexibility. The torsion spring can also cause the first gear to return to its original position when the tooth column retracts.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0018] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 This utility model is a grinding device for the inner wall of automobile tires, including a fixed frame 1, a tire body 4, and a grinding component 12. A fixed column 7 is provided on the inner side wall of the fixed frame 1, and a connecting frame 8 is fixedly provided on the outer wall of the fixed column 7. Two rotating shafts 17 are rotatably provided on the inner wall of the connecting frame 8. Gear 13 is rotatably provided on the outer wall of each of the two rotating shafts 17. A force-bearing frame 14 is fixedly provided on the outer wall of the two gear 13, and a second gear 15 is fixedly provided on the outer wall of the force-bearing frame 14. Furthermore, the two second gears 15 are respectively engaged with the gear column 11.

[0020] A limiting groove 22 is provided on the outer wall of the fixed column 7, and a toothed column 11 is slidably provided on the inner wall of the limiting groove 22. An electric telescopic rod 9 is fixedly provided at the free end of the fixed column 7, and an installation block 10 is provided between the output end of the electric telescopic rod 9 and the toothed column 11. The electric telescopic rod 9 drives the installation block 10 to move upward, and the installation block 10 drives the toothed column 11 to move upward. Since the toothed column 11 is meshed with two gears 13, one gear 13 rotates clockwise and the other rotates counterclockwise, and the two rotate synchronously. This causes the force-bearing frame 14 and gear 15 on the outer wall of the two gears 13 to rotate around the corresponding rotating shaft 17. When gear 15 is engaged with the teeth on the outer wall of the toothed column 11, the toothed column 11 cannot move downward, so that the grinding part 12 at the upper end of the toothed column 11 cannot further squeeze and grind the inside of the tire body 4, thus making the grinding force of the grinding part 12 on the tire body 4 just right. Furthermore, two support frames 3 are symmetrically arranged on the lower end face of the fixed frame 1; a support block 5 is fixedly arranged on the upper end face of the fixed frame 1, and a cylinder 6 is fixedly arranged on the upper end face of the support block 5. The output end of the cylinder 6 is connected to the anti-slip block 23; a controller 2 (the controller 2 is existing technology and is electrically connected to the electronic devices in the device) is fixedly arranged on one side wall of the fixed frame 1. Under the action of the support block 5, the anti-slip block 23 is driven to move downward by the cylinder 6, which can realize the compression of the tire body 4, making the tire body 4 more stable during grinding.

[0021] Furthermore, the grinding component 12 includes a motor 1201 fixedly mounted on the upper end face of the tooth column 11, and a grinding head 1202 is fixedly connected to the output end of the motor 1201.

[0022] A specific application of this embodiment is as follows: further, the inner wall of the connecting frame 8 has toothed grooves 16 at both ends; Gear 3 18 and fixing ring 20 are fixedly installed on both sides of gear 13 on the outer wall of the rotating shaft 17. Torsion spring 19 is fixedly installed between gear 3 18 and gear 13. A spring 21 is sleeved on the outer wall of the rotating shaft 17, and the spring 21 is fixedly connected to the fixed ring 20. The spring 21 is located between the fixed ring 20 and the inner wall of the connecting frame 8. Gear 318 and tooth groove 16 are engaged.

[0023] Furthermore, the grinding part 12 is fixedly connected to the tooth post 11; Furthermore, both pivots 17 can slide on the inner wall of the connecting frame 8.

[0024] Furthermore, the tire body 4 is located between the two support frames 3 and the anti-slip block 23, and is sleeved on the grinding head 1202. A fixing ring 20 and a gear 3 18 are fixedly installed on the outer wall of the rotating shaft 17, and the spring 21 is not fixedly connected to the inner wall of the connecting frame 8. When the rotating shaft 17 slides towards the spring 21, the gear 3 18 separates from the tooth groove 16 on the inner wall of the connecting frame 8. Under the action of the torsion spring 19, the rotating shaft 17 can be rotated to adjust the angle between the force-bearing frame 14 and the gear 2 15. When the distance between the gear 2 15 and the tooth column 11 is greater, the tooth column 11 needs to move up a greater distance to achieve the engagement between the gear 2 15 and the tooth column 11 and to lock the tooth column 11. Through this design, the thickness of the inner wall of the tire body 4 can be flexibly controlled, thereby greatly improving the practicality of the device.
