[0037] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0038] Reference Figures 1 to 7 As shown, this utility model provides a grinding device, including a sanding belt 10, a driving unit 20, a fixing member 30, and a first support member 40, wherein:

[0039] The drive unit 20 has an output end, which is driven to the sanding belt 10 to drive the sanding belt 10 to rotate.

[0040] The fixing member 30 is provided with a support part 31, which is used to support the sanding belt 10. The first support member 40 is elastically connected to the side of the fixing member 30 away from the drive part 20.

[0041] In the embodiments provided in this application, the grinding device further includes a base 100, and the driving part 20 and the fixing part 30 are both fixed on the base 100, making the structure of the grinding device more compact and easy to transport as a whole. In other embodiments, the driving part 20 and the fixing part 30 may also be separately arranged, which is not limited here. Among them, the output end 21 of the driving part, the support part 31 and the first support member 40 jointly support the sanding belt 10, that is, the output end 21 of the driving part, the support part 31 and the first support member 40 respectively support and tighten the sanding belt 10 from three positions. After the sanding belt 10 is tightened, when the output end of the driving part 20 rotates clockwise, the sanding belt 10 rotates clockwise synchronously, and when the output end of the driving part 20 rotates counterclockwise, the sanding belt 10 rotates counterclockwise synchronously.

[0042] After the sanding belt 10 is taut, it is mounted on the grinding device in a triangular shape, thereby forming multiple grinding areas on the sanding belt 10. Specifically, refer to... Figure 1 as well as Figure 2 As shown:

[0043] The portion of the abrasive belt 10 located between the support portion 31 and the first support member 40 forms the first grinding area 11. The support portion 31 is only used to provide a support point for the abrasive belt 10, so that the abrasive belt 10 between the support portion 31 and the first support member 40 forms the first grinding area 11. Since the first grinding area 11 is only supported by the tight tension of the abrasive belt 10, it is impossible to apply a large Z-axis pressure. Therefore, it is suitable for "O-to-O" polishing, that is, suitable for high-precision surface treatment. The contact pressure between the workpiece to be ground and the abrasive belt 10 should be kept very small to prevent the friction between the workpiece to be ground and the abrasive belt 10 from increasing and causing scratches on the surface of the workpiece to be ground.

[0044] Preferably, the support part 31 is made of polyurethane-coated bearing, which can support the sanding belt and facilitate the movement of the sanding belt 10 along the first preset path. Other structures or components that facilitate the operation of the sanding belt 10 can also be used for the support part 31, and there are no limitations on this.

[0045] The portion of the sanding belt 10 located on the first support member 40 forms the second grinding area 12. The second grinding area 12 is suitable for spot polishing of parts with complex small surfaces or small features. When grinding in the second grinding area 12, the pressure can be appropriately increased to improve grinding efficiency.

[0046] Preferably, the first support member 40 is a polyurethane-coated bearing, and the abrasive belt 10 can be covered on the outer circumferential surface of the polyurethane-coated bearing. During abrasion, the polyurethane-coated bearing can provide sufficient support for the abrasive belt 10 to ensure the abrasion effect. The first support member 40 can be any other structure or component that can form the second abrasion area 12, and is not limited here.

[0047] The sanding belt 10 is located on one side of the first support member 40 to form a third grinding area 13. The third grinding area 13 is located below the first support member 40. The third grinding area 13 is suitable for the workpiece to be ground that needs to be polished. The area to be ground is relatively large, and greater pressure can be applied to improve grinding efficiency.

[0048] For different polishing requirements of different parts to be polished, the corresponding polishing area can be selected for polishing, so that multiple needs can be met without frequently changing polishing equipment. While ensuring polishing quality, it also has high polishing efficiency.

[0049] In one feasible implementation, refer to Figure 3 As shown, the grinding device also includes a first elastic element 32, the two opposite ends of which are connected to the fixing element 30 and the first support element 40 respectively, so as to apply an elastic force to the first support element 40, so that the first support element 40 elastically abuts against the sanding belt 10.

[0050] When polishing the product using different polishing zones, the sanding belt 10 needs to rotate continuously. During the rotation of the sanding belt 10, a force is applied to the first support member 40, and the applied forces are different. Therefore, when the first support member 40 is subjected to the force of the sanding belt 10, the first elastic member 32 is compressed and undergoes elastic deformation to accumulate elastic force. The first elastic member 32 applies the accumulated elastic force to the first support member 40 so that the first support member 40 can always resist the sanding belt 10, thereby providing sufficient support for the sanding belt 10 and ensuring that the sanding belt 10 can polish smoothly.

[0051] Preferably, the first elastic element 32 is a spring, one end of which is connected to the fixing element 30 and the other end of which is connected to the first support element 40. During the rotation of the sanding belt 10, the spring can apply a corresponding elastic force to the first support element 40 according to the force acting on the first support element 40, so that the first support element 40 provides sufficient support for the sanding belt 10 to ensure the smooth operation of the sanding belt 10.

[0052] In other embodiments, the first elastic member 32 may be selected from other structures or components capable of applying elastic force to the first support member 40, and no limitation is made here.

[0053] Furthermore, referring to Figures 1 to 3 As shown, the grinding device also includes a first adjusting member 50. One end of the first adjusting member 50 is connected to the first support member 40, and the other end of the first adjusting member 50 is connected to the first elastic member 32. The elastic force accumulated by the first elastic member 32 can be transmitted to the first support member 40 through the first adjusting member 50, so that the first support member 40 abuts against the sanding belt 10.

[0054] Reference Figure 6 As shown, the function of the first adjusting member 50 is to adjust the position of the first support member 40 in the first direction D1. The first direction D1 is the direction in which the first support member 40 rotates in the horizontal plane. During the grinding process, when the position of the sanding belt 10 is offset, the angle of the first support member 40 can be adjusted by the first adjusting member 50 so that the first support member 40 can still completely abut against the sanding belt 10, thereby providing a stable support force to the sanding belt 10 and ensuring a stable grinding effect.

[0055] Preferably, refer to Figure 3 , Figure 6 as well as Figure 7 As shown, the first adjusting member 50 includes a second elastic member 51 and an adjusting seat 52. The first supporting member 40 is movably connected to the adjusting seat 52 along the first direction D1. The two opposite ends of the second elastic member 51 abut against the adjusting seat 52 and the first supporting member 40 respectively, so as to apply an elastic force to the first supporting member 40 and adjust the position of the first supporting member 40 in the first direction D1.

[0056] When the position of the sanding belt 10 is offset, the first support member 40 can be rotated along the first direction D1 to a suitable position and fixed after it is completely against the sanding belt 10. During the movement of the first support member 40, the second elastic member 51 is compressed and undergoes elastic deformation to accumulate elastic force. After the first support member 40 is fixed, the second elastic member 51 applies elastic force to the first support member 40 so that the first support member 40 can be maintained in the corresponding position to stably support the sanding belt 10.

[0057] When the first support member 40 needs to be reset, the fixation of the first support member 40 is released, and the elastic force accumulated by the second elastic member 51 can drive the first support member 40 to return to the initial position (the position when the sanding belt 10 has not shifted) along the first direction D1.

[0058] To maintain the stability of the first support member 40, a rotating shaft 53 is provided on the adjusting seat 52. The first support member 40 is rotatably mounted on the rotating shaft 53, and the rotation center of the rotating shaft 53 is parallel to the rotation center of the drive unit 20. The first support member 40 can rotate along the first direction D1 with the rotating shaft 53 as the central axis. After the first support member 40 rotates to a suitable position along the first direction D1, the rotating shaft 53 can provide support for the end of the first support member 40 near the sanding belt 10, so that the first support member 40 is held in the corresponding position. When the second elastic member 51 drives the first support member 40 to reset, the first support member 40 rotates along the rotating shaft 53 to the initial position. The rotating shaft 53 can provide stable support for the first support member 40 on the one hand, and ensure that the first support member 40 moves stably along the first direction D1 on the other hand.

[0059] In other embodiments, the first adjusting member 50 may be other structures or components capable of adjusting the first support member 40 to move in the first direction D1, and no limitation is made here.

[0060] During the sanding process, in order to ensure that the first support member 40 can remain in contact with the sanding belt 10, thereby guaranteeing the sanding effect and preventing sanding accidents, the embodiments provided in this application refer to... Figures 1 to 5 As shown, the grinding device includes a second adjusting member 60, which is disposed on the fixing member 30. The first adjusting member 50 can move along a first preset path, and the second adjusting member 60 can move along a second preset path. When the first adjusting member 50 moves along the first preset path, it can drive the second adjusting member 60 to move along the second preset path. When the second adjusting member 60 moves along the second preset path, the second adjusting member 60 and the first adjusting member 50 remain in abutment against each other.

[0061] The first preset path is the trajectory of the first adjusting member 50 moving horizontally left and right. When the first support member 40 is subjected to different forces from the sanding belt 10, it will move horizontally left and right, thereby driving the first adjusting member 50 to move along the first preset path. When the first adjusting member 50 moves along the first preset path, it can drive the second adjusting member 60 to move along the second preset path. The function of the second adjusting member 60 moving along the second preset path is to ensure that the first adjusting member 50 and the second adjusting member 60 can maintain a resisting relationship, so as to ensure that the first adjusting member 50 moves stably along the first preset path, thereby enabling the first support member 40 and the sanding belt 10 to maintain a stable resisting state.

[0062] In one feasible embodiment, the second adjusting member 60 includes a third elastic member 61 and a stop rod 62. The stop rod 62 can move along a second preset path, which is the trajectory of the stop rod 62 rotating along a first direction D1. The stop rod 62 includes a first end and a second end. One end of the third elastic member 61 is connected to the fixing member 30, and the other end of the third elastic member 61 is connected to the first end of the stop rod 62. The second end of the stop rod 62 abuts against the first adjusting member 50.

[0063] When the first adjusting member 50 moves along the first preset path, the second end of the stop rod 62 abuts against the first adjusting member 50, so the second end of the stop rod 62 can move along the second preset path under the drive of the first adjusting member 50. When the first adjusting member 50 moves along the first preset path, the stop rod 62 moves synchronously along the second preset path. During the movement, the third elastic member 61 is compressed and undergoes elastic deformation to accumulate elastic force. This elastic force supports the stop rod 62, so that the second end of the stop rod 62 always abuts against the first adjusting member 50.

[0064] The stop rod 62 can limit the movement of the first adjusting member 50 during its movement, preventing it from exceeding the predetermined range, so as to keep the position of the first adjusting member 50 fixed, thereby fixing the position of the first supporting member 40.

[0065] Furthermore, referring to Figure 6 as well as Figure 7 As shown, the first adjusting member 50 has a guide slope 54. When the first adjusting member 50 moves along the first preset path, the second end of the stop rod 62 abuts against the guide slope 54. During the movement of the first adjusting member 50 along the first preset path, the guide slope 54 provides an inclined contact surface for the stop rod 62, so that the stop rod 62 can generate a force (reaction force) opposite to the direction of movement of the first adjusting member 50 during the sliding process. This force can offset or reduce the shaking or vibration that may occur during the movement of the first adjusting member 50, thereby making the movement of the first adjusting member 50 more stable. This ensures that the sanding belt 10 of the first support member 40 moves smoothly on the surface of the workpiece during grinding, thereby improving the grinding quality.

[0066] By cooperating with the guide ramp 54 and the stop rod 62, the movement trajectory and speed of the first adjusting member 50 can be precisely controlled to ensure that it moves stably along the preset path.

[0067] In other embodiments, the second adjusting member 60 may be other structures or components that enable the first support member 40 to remain in contact with the sanding belt 10, and no limitation is made here.

[0068] Reference Figure 6 as well as Figure 7 As shown, the adjusting seat 52 is provided with a second support member 70. The second support member 70 is located between the adjusting seat 52 and the sanding belt 10. The second support member 70 is used to support the sanding belt 10. The second support member 70 is located below the adjusting seat 52 and at the position of the third grinding area 13. Since the third grinding area 13 can apply greater pressure for grinding, the second support member 70 can provide sufficient support to the sanding belt 10 so that the sanding belt 10 can be kept taut.

[0069] In one feasible embodiment, the second support member 70 includes a fourth elastic member 71, which abuts against the sanding belt 10. One end of the fourth elastic member 71 is fixed to the adjusting seat 52, and the other end of the fourth elastic member 71 abuts against the adjusting seat 52. The other end of the fourth elastic member 71 can move along the second direction D2 to apply an elastic force to the sanding belt 10 to support it. The second direction D2 is the extension direction of the fourth elastic member 71. When the other end of the fourth elastic member 71 moves along its extension direction, its supporting force on the sanding belt 10, that is, the pressure applied to the sanding belt 10, can be adjusted. Thus, the position of the other end of the fourth elastic member 71 can be adjusted according to the grinding requirements so that the sanding belt 10 obtains suitable pressure.

[0070] Preferably, the fourth elastic element 71 is a spring sheet. One end of the spring sheet is fixed to the adjusting seat 52, the free end of the spring sheet abuts against the adjusting seat 52, the main body of the spring sheet abuts against the sanding belt 10, and when the other end of the spring sheet moves on the surface of the adjusting seat 52, the spring sheet undergoes elastic deformation and accumulates elastic force, and applies the elastic force to the sanding belt 10. Thus, according to the grinding requirements, the free end of the spring sheet can be moved to a suitable position to meet the pressure requirements of the sanding belt 10.

[0071] In other embodiments, the second support 70 may be other structures or components capable of supporting the sanding belt 10, and is not limited here.

[0072] The above description, based on the embodiments shown in the drawings, details the structure, features, and effects of this utility model. The above description is only a preferred embodiment of this utility model, but the scope of implementation of this utility model is not limited to what is shown in the drawings. Any changes made in accordance with the concept of this utility model, or modifications to equivalent embodiments, that do not exceed the spirit covered by the specification and drawings, shall be within the protection scope of this utility model.
