[0003] The patent document with patent publication number "CN221911146U" discloses "an aviation tire corner grinding device", which can grind the tire by driving the tire to rotate and cooperating with the grinding block; however, it was found in application that its grindable surface is too limited, and its flexibility in use is insufficient, and it cannot adapt to grinding multiple positions on the tire. Utility Model Content

[0004] The purpose of this application is to provide a tire corner grinding device to solve at least one of the above technical problems.

[0005] In order to solve the above technical problems, the present application provides a tire corner grinding device, comprising a base;

[0006] a rotating seat and a first rotating drive assembly, wherein the rotating seat is rotatably mounted on the base, and the first rotating drive assembly is used to drive the rotating seat to rotate;

[0007] A fixing assembly, the fixing assembly being arranged on the rotating seat and being used to fix the tire and drive the tire to rotate;

[0008] A grinding assembly and a first driving assembly, wherein the first driving assembly and the grinding assembly are both arranged on the base, and the first driving assembly is used to drive the grinding assembly to approach or move away from the fixed assembly along a first direction;

[0009] a cleaning assembly and a second driving assembly, wherein the cleaning assembly is slidably disposed on the base along a first direction, and the second driving assembly is used to drive the cleaning assembly along the first direction toward or away from the fixed assembly;

[0010] In the above implementation process, the staff fixes the tire to be polished on the fixed component, and the fixed component can drive the tire to rotate. When the tire rotates, it contacts the polishing component and thus the tire tread can be polished. It can be understood that the first drive component can drive the polishing component to move to control the spacing between the remaining tires. When the polishing position needs to be adjusted, the rotating seat can be driven to rotate by the first rotating drive component. At this time, different surfaces of the tire can be in contact with the polishing component, thereby realizing multi-angle polishing and improving the flexibility of polishing; and during the polishing process, the second drive component can drive the cleaning component close to the tire, and the cleaning component acts on the tire and cooperates with the rotation of the tire to clean the tire in time, so that the tire polishing process and cleaning process can be realized synchronously, effectively improving work efficiency.

[0011] Preferably, the fixing assembly includes a mounting bracket, a second rotation drive assembly and a mounting seat;

[0012] The mounting seat is suitable for mounting and fixing a tire, the mounting frame is mounted on the rotating seat, and the second rotation driving component is mounted on the mounting frame and is suitable for driving the mounting seat to rotate;

[0014] Preferably, the polishing assembly includes a stand, a mounting column and a polishing unit;

[0015] The stand is provided at the driving end of the first driving assembly, the mounting post is provided on the stand, and the grinding unit is provided on the mounting post;

[0017] Preferably, the polishing unit is detachably connected to the mounting column;

[0018] In the above implementation process, the grinding unit is detachably connected to the mounting post, that is, the grinding unit can be replaced after being used for a period of time, thereby preventing the outer surface of the grinding unit from becoming smooth and affecting the grinding effect on the tire.

[0019] Preferably, a limiting column is formed at the end of the mounting column, and the limiting column includes an axial portion and a plurality of protrusions extending radially along the axial portion; a limiting groove adapted to the limiting column is formed on the axis of the grinding unit;

[0021] Preferably, the protrusions are provided in 2-6 numbers and are distributed at equal angles;

[0022] In the above implementation process, this solution further optimizes the structure of the limit column and the limit groove. Since the protrusions are distributed at equal angles, after the grinding unit has been used for a period of time, the staff can rotate the grinding unit to a certain angle and then insert it into the limit column to fix the grinding unit. In this way, the unused surface of the grinding unit can face the tire, thereby fully utilizing the grinding unit and reducing the frequency of replacing the grinding unit.

[0023] Preferably, the first driving assembly includes a first slider, a fixing seat, a screw rod and a rotating motor;

[0024] The fixing seat is arranged on the base, the screw rod is rotatably arranged on the fixing seat and is arranged on the driving end of the rotating motor, and the first slider is threadedly engaged with the screw rod;

[0025] In the above implementation process, the fixed seat provides support for the screw, and the rotating motor drives the screw to rotate. The rotation of the screw can drive the first slider that cooperates with its thread to move. The first slider moves along the axial direction of the screw, that is, moves in the first direction, thereby driving the grinding assembly to move.

[0026] Preferably, the cleaning assembly includes a brush holder and a brush body provided on the brush holder;

[0027] In the above implementation process, the brush holder provides a mounting position for the brush body, and the brush body can abut against the outer surface of the tire, thereby cleaning the outer surface of the tire and reducing dust and impurities attached to the tire surface.

[0028] Preferably, the cross section of the brush holder is U-shaped;

[0029] In the above implementation process, the cross section of the brush holder is U-shaped, which can better adapt to the tire after rotation adjustment and achieve more comprehensive cleaning of the tire.

[0030] Preferably, the second driving assembly includes a driving cylinder, a slide rail extending along the first direction, and a second slider slidably arranged on the slide rail;

[0031] The brush holder is arranged on the second slider, and the driving end of the driving cylinder is connected to the brush holder or the second slider;

[0032] In the above implementation process, the second slider cooperates with the slide rail to achieve smooth movement of the second slider; the driving cylinder can drive the second slider or the brush holder to move so as to move the brush body closer to or away from the tire.

[0033] Compared with the prior art, the beneficial effects of the present application are: this solution drives the grinding assembly to move through the first drive assembly to control the spacing between the remaining tires. When the grinding position needs to be adjusted, the first rotating drive assembly can be used to drive the rotating seat to rotate.
