Those skilled in the art will understand the specific meaning of these terms in this application.

[0027] This application provides a grinding tool. Figure 1 and Figure 2The overall structural diagram and enlarged regional diagram of the grinding tool in this application are shown respectively, as follows: Figure 1 and Figure 2 As shown, a grinding tool includes a frame 1 and a working mechanism 2 connected thereto. The working mechanism 2 includes an adjustment auxiliary mechanism, a connecting shaft 20, an adjusting wheel 22, and a working panel 28. The adjusting wheel 22 is used to provide tension during the processing to ensure that the abrasive belt reaches the specified tension during grinding, thus ensuring the quality of the processed workpiece. The adjusting wheel 22 is sleeved on one end of the connecting shaft 20 and is located on the front side of the working panel 28. A rotary bearing is installed on the outer wall of the end of the connecting shaft 20 that is connected to the adjusting wheel 22. The outer wall of the rotary bearing is connected to the adjusting wheel 22. The rotary bearing is a key component between the connecting shaft 20 and the adjusting wheel 22, ensuring that the adjusting wheel 22 rotates smoothly and flexibly around the connecting shaft 20. At the same time, the ball bearing inside the rotary bearing can reduce the friction between the two and extend their service life.

[0028] Furthermore, the other end of the connecting shaft 20 passes through the back of the working panel 28 and is connected to the adjustment auxiliary mechanism. The adjustment auxiliary mechanism adjusts and corrects the position and tension of the abrasive belt by adjusting the position relationship of the adjusting wheel 22, ensuring the normal operation and performance of the grinding tool. The adjustment auxiliary mechanism includes an adjustment frame 34, an elastic body 36, an adjusting element 37, a first adjusting plate 33, and a telescopic rod 31. The adjustment frame 34 is fixedly connected to the first adjusting plate 33. At the same time, the adjustment frame 34 is sleeved on the outside of the connecting shaft 20 and connected to the bottom of the connecting shaft 20.

[0029] Specifically, one end of the adjusting member 37 passes through the adjusting frame 34 and abuts against the elastic body 36 via the connecting shaft 20. The other end of the adjusting member 37 is threadedly connected to the adjusting frame 34 and is perpendicular to the connecting shaft 20. In some preferred embodiments of this application, the elastic body 36 and the adjusting member 37 are respectively arranged radially on both sides of the connecting shaft 20, and both ends of the elastic body 36 abut against the inner walls of the connecting shaft 20 and the adjusting frame 34, respectively. The outer wall of the adjusting member 37 is provided with a threaded structure. By turning the adjusting member 37 clockwise or counterclockwise, the relative position of the adjusting member 37 and the elastic body 36 can be changed to adjust the balance of the adjusting wheel 22.

[0030] Furthermore, one end of the first adjusting plate 33 is rotatably connected to the rotating shaft of the working mechanism 2, and the other end is provided with a handle 32. During the adjustment process, the operator controls the swing amplitude of the first adjusting plate 33 through the handle 32. One end of the telescopic rod 31 is fixedly connected to the working mechanism 2, and the other end is telescopically connected to the first adjusting plate 33. During the adjustment process, the telescopic rod 31 can effectively support the first adjusting plate 33 to ensure the telescopic effect.

[0031] Furthermore, the grinding tool also includes at least one set of symmetrically arranged second adjusting plates 38. The frame 1 is rotatably connected to the working mechanism 2 through the second adjusting plates 38. The second adjusting plate 38 is provided with an arc-shaped slide groove 39. One end of the second adjusting plate 38 is fixedly connected to the working mechanism 2, and the other end is rotatably connected to the frame 1 through the slide groove 39. In actual work, due to the different shapes of the workpieces being processed, some workpieces are prone to grinding dead corners, leading to uneven grinding and quality problems. Therefore, in the grinding tool of this application, during operation, the working mechanism 2 can achieve multi-angle rotation through the cooperation of the second adjusting plate 38 and the slide 39. During installation, the most suitable grinding angle is found, the bolts are loosened, and the working mechanism 2 is rotated. The bolts are always located in the slide 39. At this time, the slide 39 has a guiding function. When the bolts are rotated for adjustment, they can only move along the direction of the slide, which can effectively prevent the misalignment of the working mechanism 2. After the working mechanism 2 reaches the predetermined angle, the locking bolts are tightened to fix the working mechanism 2. The cooperation between the slide 39 and the bolts can improve stability and reliability.

[0032] like Figure 1 and Figure 3As shown, the working mechanism 2 further includes a motor 23, a sanding belt 24, a drive wheel 21, and a contact wheel 25. The motor 23 is fixedly mounted on the back of the working panel 28, and its output end is connected to the drive wheel 21. The drive wheel 21 and the contact wheel 25 are located on the front of the working panel 28. The drive wheel 21, the adjusting wheel 22, and the contact wheel 25 are connected by the sanding belt 24. Further, the working mechanism 2 also includes an extension arm 26. One end of the extension arm 26 is fixedly mounted on the working panel 28, and the other end extends away from the drive wheel 21 and is fixedly connected to the contact wheel 25 through a locking structure. The end of the extension arm 26 has an opening slot. The contact wheel 25 can be locked and loosened by the engagement of a bolt with the opening slot. When different molds need to be changed, the bolt can be rotated to disassemble and replace the mold. In addition, the drive wheel 21, the adjusting wheel 22 and the contact wheel 25 are arranged in a three-point configuration, with the adjusting wheel 22 positioned above the drive wheel 21 and the contact wheel 25 mounted at the end of the extension arm 26.

[0033] Furthermore, the working mechanism 2 also includes a first mounting block 27 fixedly mounted on the extension arm 26, the first mounting block 27 being used to mount a worktable for placing the workpiece.

[0034] Furthermore, the contact wheel 25 includes one of a flat grinding mold, an arc grinding mold, a circular grinding mold, and a shaped grinding mold, and the corresponding mold can be selected according to the actual grinding requirements.

[0035] First, adjust the working mechanism 2 to a predetermined angle and lock it. Then, start the motor 23. The motor 23 drives the drive wheel 21 to rotate, which in turn drives the adjusting wheel 22 and the contact wheel 25 to rotate through the sanding belt 24. Place the workpiece to be sanded on the worktable for sanding. During the sanding process, adjust the tension of the adjusting wheel 22 and the position of the sanding belt 24 by adjusting the first adjusting plate 33 and the adjusting component 37 to achieve the best sanding effect.

[0036] The specific embodiments of this application have been described in detail above. For those skilled in the art, several improvements and modifications can be made to this application without departing from the principle of this application, and these improvements and modifications also fall within the protection scope of the claims of this application.
