[0042] Example 1:

[0043] Please see Figure 1 This embodiment provides a wheel dressing tool for use on a belt sander 500 ( Figure 3 As shown in the figure, the belt sander 500 includes a first sanding belt 510, which includes: a base body 100, a first connecting part 200 and a grinding part 300. The first connecting part 200 is disposed on the base body 100 and is used to connect with the robot arm 400 of the belt sander 500. The grinding part 300 is disposed on the base body 100 and is used to abut against the first sanding belt 510. When the first sanding belt 510 moves, the robot arm 400 drives the grinding part 300 to move to one side of the first sanding belt 510 and causes the grinding part 300 to grind the first sanding belt 510.

[0044] During the grinding process of the belt sander 500, the workpiece is concentrated in a certain area of ​​the sander belt for a long time, which can easily lead to pitting defects on the surface of the sander belt, which may affect the processing quality and even cause safety hazards. In this embodiment, the dressing tool is used to grind the first sander belt 510 of the belt sander 500 to keep the first sander belt 510 flat.

[0045] For example, please combine Figure 2As shown, the first abrasive belt 510 typically includes region a, region b, and region c, which are connected sequentially. Region b is located in the middle region, and the workpiece is concentrated in region b for a long time. After working for a period of time, the thickness of regions a and c is greater than the thickness of region b, that is, region b will have depressions or collapses. Therefore, in this embodiment, a grinding wheel is used to grind regions a, b, and c to make the thickness of the entire first abrasive belt 510 uniform, so that the surface of the first abrasive belt 510 remains flat.

[0046] The wheel repairer includes a base body 100, a first connecting part 200, and a grinding part 300. The base body 100 is provided with the first connecting part 200 and the grinding part 300. The first connecting part 200 is used to mount the base body 100, and the grinding part 300 is used to abut against the first sanding belt 510. When the motor drives the first sanding belt 510 to rotate at high speed, the grinding part 300 is kept in contact with the first sanding belt 510. The grinding part 300 is relatively fixed. Through the friction between the grinding part 300 and the first sanding belt 510, the grinding part 300 grinds the entire surface of the first sanding belt 510 and controls the grinding thickness to keep the surface of the first sanding belt 510 flat, thereby solving the problem of sanding belt dents. This can reduce the need to replace the first sanding belt 510, save costs, and the wheel repairer has a simple structure and is easy to implement.

[0047] It is understandable that the wheel dressing device can be made of wear-resistant material. Controlling the feed movement of the wheel dressing device, i.e., controlling the feed movement of the robotic arm 400, can control the grinding thickness of the first abrasive belt 510. The feed movement of the wheel dressing device can be achieved by the robotic arm 400, which is considered existing technology and will not be elaborated further.

[0048] In this embodiment, the robot arm 400 can fix the wheel dressing device and drive it to move towards the first sanding belt 510, so as to perform grinding and dressing on the first sanding belt 510 through the wheel dressing device. At the same time, the robot arm 400 can clamp the workpiece, that is, clamp the workpiece and polish it through the first sanding belt 510. In other words, the belt sander 500, the robot arm 400 and the first sanding belt 510 can all be understood as prior art. The specific structure of the belt sander 500, the robot arm 400 and the first sanding belt 510 will not be described in detail.

[0049] Specifically, please refer to Figure 1 The grinding part 300 has a circumferential structure and is disposed on the outer wall of the base body 100.

[0050] In this embodiment, the grinding part 300 has a circumferential structure, that is, the grinding part 300 is circular. The circle has no sharp edges and corners. The circumferential structure has high bending strength, and during grinding, the cutting force is evenly transmitted along the circumference, which can disperse stress.

[0051] Specifically, please refer to Figure 1 and Figure 4 A first through hole 110 is provided in the middle of the base body 100, and a first connecting part 200 is provided on the inner wall of the first through hole 110.

[0052] In this embodiment, the first connecting part 200 is used to install the base body 100. For example, the first connecting part 200 can be connected to the chuck of the robot arm 400. The first connecting part 200 is on the inner wall of the first through hole 110. When installing the base body 100, the base body 100 can be sleeved on the chuck through the first through hole 110, so that the first connecting part 200 and the chuck can be connected in a cooperative manner, making installation convenient.

[0053] Specifically, please refer to Figure 4 The first through hole 110 includes a first through hole 111, a second through hole 112 and a third through hole 113 connected in sequence, and the diameter of the first through hole 111 is larger than the diameter of the second through hole 112, and the diameter of the second through hole 112 is larger than the diameter of the third through hole 113.

[0054] In this embodiment, the first through hole 110 includes a first through hole 111, a second through hole 112, and a third through hole 113 connected in sequence. It can be understood that the first through hole 111 is distributed at the bottom of the mounting base, and the diameter of the first through hole 111 is larger than the diameter of the second through hole 112, and the diameter of the second through hole 112 is larger than the diameter of the third through hole 113. That is, the first through hole 111, the second through hole 112, and the third through hole 113 can form a stepped structure. This stepped structure can play a limiting role. For example, the chuck is connected to the first through hole 111, the second through hole 112, and the third through hole 113. The stepped structure can restrict the movement of the base body 100, so that the base body 100 is fixed on the chuck. When installing the base body 100, the base body 100 is simply put on the chuck, which is convenient for installation.

[0055] To prevent axial misalignment when the base body 100 and the robot arm 400 are connected, the first connecting part 200 is provided with a first locking part, and correspondingly, the robot arm 400 is provided with a second locking part that mates with the first locking part. When the wheel repairer is installed on the robot arm 400, the first locking part and the second locking part engage to limit movement and facilitate easy assembly and disassembly. For example, the first locking part can be a protruding structure, and the second locking part can be a grooved structure.

[0056] Specifically, please refer to Figure 5 The first snap-fit ​​portion includes: a plurality of recessed portions 210 and a plurality of protruding portions 220, wherein the recessed portions 210 are disposed on the inner wall of the first through hole 110 and the protruding portions 220 are disposed on the inner wall of the first through hole 110.

[0057] In this embodiment, the first snap-fit ​​portion is snapped into the second snap-fit ​​portion by a plurality of recessed portions 210 and a plurality of protruding portions 220, so as to play a limiting role, ensuring stable connection and convenient assembly and disassembly.

[0058] Specifically, please refer to Figure 5 The recessed portion 210 may include a first recess 211, a second recess 212, and a third recess 213. The first recess 211 is disposed on the inner wall of the first through hole 111, the second recess 212 is disposed on the inner wall of the second through hole 112, and the third recess 213 is disposed on the inner wall of the third through hole 113. The protruding portion 220 includes a second outward protrusion 221 and a third outward protrusion 222. The second outward protrusion 221 is disposed on the inner wall of the second through hole 112, and the third outward protrusion 222 is disposed on the inner wall of the third through hole 113.

[0059] In this embodiment, the first through hole 110 is composed of a first through hole 111, a second through hole 112, and a third through hole 113. The diameter of the first through hole 111 is larger than the diameter of the second through hole 112, and the diameter of the second through hole 112 is larger than the diameter of the third through hole 113. A first concave portion 211 is provided within the first through hole 111, a second concave portion 212 and a second convex portion 221 are provided within the second through hole 112, and a third concave portion 213 is provided within the third through hole 113. With the third outward protrusion 222, when the wheel repairer is inserted into the robot arm 400, the wheel repairer only needs to be aligned with the robot arm 400, and then the wheel repairer can automatically slide into the robot arm 400 and automatically lock through the step structure. At the same time, the first inner concave 211, the second inner concave 212, the third inner concave 213, the second outward protrusion 221 and the third outward protrusion 222 can restrict the movement of the base body 100, prevent the base body 100 from rotating, ensure stable connection, facilitate disassembly and assembly, and improve installation efficiency.

The belt sander dressing device is disposed on the chuck member 430. The moving part 410 is used to drive the chuck base 420 to move, so that the chuck member 430 drives the belt sander dressing device to move towards the first sander belt 510, so that the grinding part 300 of the belt sander dressing device can grind the first sander belt 510.

[0064] In this embodiment, the chuck 430 is provided with a second locking part. When installing the wheel dressing tool and the robot arm 400, the wheel dressing tool can be sleeved on the robot arm 400, so that the first locking part is locked with the second locking part on the robot arm 400. The chuck base 420 is driven to move towards the first sanding belt 510 by the moving part 410, so that the grinding part 300 on the wheel dressing tool abuts against the depression of the first sanding belt 510. Then, the first sanding belt 510 is driven to rotate by the motor to grind the depression defect 511. Then, the grinding part 300 is controlled to move to the left by the moving part 410 to grind the left side of the depression defect 511. Then, the grinding part 300 is controlled to move to the right by the moving part to grind the right side of the depression defect 511, so as to achieve grinding of the entire first sanding belt 510.

[0065] In this embodiment, the moving part 410, the chuck base 420 and the chuck 430 can be understood as prior art, and their specific structures will not be described in detail.
