[0002] A tire is an annular elastic rubber product that rolls on the ground and is assembled on various vehicles or machinery. It is usually installed on a metal rim, can support the vehicle body, buffer external impacts, achieve contact with the road surface, and ensure the driving performance of the vehicle. Tires are often used under complex and harsh conditions. When driving, they are subjected to various deformations, loads, forces, and high and low temperatures. Therefore, they must have high load-bearing performance, traction performance, and buffering performance. At the same time, they are also required to have high wear resistance and flex resistance, as well as low rolling resistance and heat generation. Therefore, wear resistance detection is required after tire production and processing.

[0003] The existing detection devices have poor flexibility, are not convenient for supporting and limiting tires of different specifications, have a relatively single scope of application, reduce the practicality of the detection device, and the friction pads are not convenient for disassembly and replacement, affecting the detection efficiency. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide a tire wear resistance detection device to solve the problems of poor flexibility of the existing detection device, inconvenience in supporting and limiting tires of different specifications, relatively single scope of application, reduction of the practicality of the detection device, and inconvenience in disassembly and replacement of the friction pads, which affect the detection efficiency as mentioned in the above background art.

[0005] To achieve the above object, the utility model provides the following technical solution: A tire wear resistance detection device, including a workbench, a fixed plate is fixedly connected to the top of the workbench, a first motor is fixedly connected to one side of the fixed plate, a rotating shaft is fixedly connected to the output end of the first motor, second electric push rods are fixedly connected to the outside of the rotating shaft in a circular shape, a top plate is fixedly connected to the output end of the second electric push rods, second chutes are symmetrically arranged on one side inside the workbench, a bidirectional threaded rod is rotatably connected to the inside of the second chutes, moving plates are symmetrically threaded and connected to the outside of the bidirectional threaded rod, a cylinder is fixedly connected to the top of the moving plates, a detection plate is fixedly connected to the output end of the cylinder, and a friction pad is snap-fitted inside the detection plate.

[0007] Preferably, a first electric push rod is fixedly connected to one side of the movable plate, the first electric push rod and the first chute are fixedly connected, and the rotating shaft is rotatably connected to the movable plate through a rotating seat.

[0008] Preferably, a first spring is fixedly connected between the outer side of the rotating shaft and one side of the top plate.

[0009] Preferably, limiting rods are symmetrically and fixedly connected inside the second sliding groove, and the limiting rods are slidably connected with the moving plate.

[0010] Preferably, one end of the bidirectional threaded rod is fixedly connected to the output end of the second motor, and the second motor is fixedly connected to the workbench.

[0011] Preferably, pulling plates are symmetrically arranged on one side of the detection plate, and the pulling plates are fixedly connected to the detection plate through second springs.

[0012] Preferably, positioning columns are fixedly connected to one side of each pulling plate, and the positioning columns are snap-connected with the friction pads.

[0013] Compared with the prior art, the utility model provides a tire wear resistance detection device, which has the following beneficial effects:

[0014] 1. By arranging the second electric push rod and the detection plate, the tire is placed outside the top plate through one end of the rotating shaft. Then, the second electric push rod is started to push the top plate into contact with the inner side of the tire, which is convenient for adjusting the position of the top plate, realizing that the detection device supports and fixes tires of different specifications and sizes, increasing the application range and practicability of the detection device. Moreover, there are multiple second electric push rods and top plates, which can simultaneously perform wear resistance detection on multiple tires.

Then, the friction pads are snap-connected to the inner side of the detection plate. After releasing the pulling of the pulling plates, the second springs drive the pulling plates and the positioning columns to reset, realizing the snap connection between the positioning columns and the friction pads and fixing the positions of the friction pads. The operation is simple and fast, which is convenient for installing and replacing the friction pads, thus improving work efficiency.

[0015] 2. By arranging the air cylinder, when one part of the friction pad is worn after being in contact with the tire for a period of time, there will be more rubber on the surface of the friction pad in contact with the tire, which will reduce the friction coefficient of the friction pad. At this time, the air cylinder can be used to push the detection plate and the friction pad to move up and down, so that the tire contacts with other parts of the friction pad, and the wear resistance detection can be continued, ensuring the detection effect, increasing the service life of the friction pad at the same time, avoiding waste of resources, and reducing the detection cost.

[0034] The working principle and usage process of the present utility model: When in use, first, the position of the movable plate 4 is moved by the first electric push rod 5, so that the rotating shaft 7 is separated from the rotating seat 8.

Then, the first motor 6 is started to drive the structures such as the rotating shaft 7, the second electric push rod 9, and the top plate 10 to drive the tire to rotate for wear resistance detection work. During the use process, when a certain part of the friction pad 19 wears against the tire for a period of time, there will be more rubber on the surface of the friction pad 19 in contact with the tire, thereby reducing the friction coefficient of the friction pad 19. At this time, the cylinder 17 can push the detection plate 18 and the friction pad 19 to move up and down, making the tire contact with other parts of the friction pad 19, continuing the wear resistance detection, ensuring the detection effect, increasing the service life of the friction pad 19 at the same time, avoiding waste of resources, and reducing the detection cost.
