[0026] In use, the heat dissipation fin workpiece to be polished is placed on the workbench 3, the corresponding sliding rod 7 is driven by the sliding piece to drive the clamping mechanism to approach the workbench 3, the clamping mechanism gradually approaches the heat dissipation fin workpiece on the workbench 3, then the corresponding end of the heat dissipation fin workpiece is clamped by the clamping mechanism, at this time the heat dissipation fin workpiece can be polished; after the non-clamped area of the heat dissipation fin workpiece is polished, the heat dissipation fin workpiece is released by the clamping mechanism, then the clamping mechanism is driven away from the workbench 3 by the corresponding sliding rod 7 driven by the sliding piece, so that the clamping mechanism is separated from the heat dissipation fin workpiece, then the mounting plate 6 and the sliding rod 7 are rotated horizontally by the rotating piece 5 to drive the rotating ring 4, the clamping mechanism is moved to the position aligned with the polished position of the heat dissipation fin workpiece, then the clamping mechanism is driven to approach the workbench 3 by the corresponding sliding rod 7 driven by the sliding piece, so that the clamping mechanism clamps the end of the heat dissipation fin workpiece after polishing, then the previous clamped position of the heat dissipation fin workpiece can be polished, thereby helping to ensure the uniformity of the size of the heat dissipation fin after polishing.

By starting the first cylinder 16, the first cylinder 16 drives the corresponding sliding rod 7 to slide, so as to drive the corresponding clamping mechanism to slide towards the direction of approaching or moving away from the workbench 3. In other embodiments, the first cylinder 16 can be replaced by an electric cylinder, an electric push rod or the like.

[0030] With reference to Figure 1 And Figure 2 , in order to facilitate the clamping and fixing of the heat dissipation fin workpiece, the clamping mechanism includes a lifting rod 12, a rotating frame 13, a clamping block 14, a first driving member, a second driving member and a third driving member, the lifting rod 12 is slidingly arranged at one end of the corresponding sliding rod 7 away from the abutting portion 62, the sliding direction of the lifting rod 12 is parallel to the rotation axis of the rotating ring 4, specifically, the one end of the sliding rod 7 away from the abutting portion 62 is fixed with a sliding block (not shown in the figure), a sliding groove 17 is formed on the lifting rod 12 and slidingly matched with the corresponding sliding block, so that the lifting rod 12 and the corresponding sliding rod 7 will not be separated, the first driving member is arranged on the sliding rod 7, and the first driving member is used to drive the corresponding lifting rod 12 to slide.

[0031] With reference to Figure 1 And Figure 2 , further, the first driving member includes a second cylinder 18 mounted on the corresponding sliding rod 7, the extension direction of the second cylinder 18 is parallel to the sliding direction of the lifting rod 12, the second cylinder 18 is located below the sliding rod 7, and the one end of the lifting rod 12 away from the workbench 3 is fixedly connected with the piston rod of the corresponding second cylinder 18 through a support block. In other embodiments, the second cylinder 18 can be replaced by an electric cylinder, an electric push rod, etc.

[0032] With reference to Figure 1 And Figure 2 , the rotating frame 13 is U-shaped, the rotating frame 13 is rotationally arranged on the side of the corresponding lifting rod 12 close to the workbench 3, the opening of the rotating frame 13 is arranged towards the direction of the workbench 3, facilitating the workpiece to move into the opening of the rotating frame 13, the rotation axis of the rotating frame 13 is parallel to the sliding direction of the sliding rod 7, the second driving member is arranged on the lifting rod 12, and the second driving member is used to drive the rotating frame 13 to rotate; specifically, the second driving member includes a second motor 19 fixedly installed on the lifting rod 12, the second motor 19 is a reduction motor, and the rotating frame 13 is coaxially fixed with the output shaft of the corresponding second motor 19. In other embodiments, the second motor 19 can be replaced by a driving motor, a stepping motor, etc.

[0033] With reference to Figure 1 And Figure 2The clamping blocks 14 are slidably mounted on the rotating frame 13. Two clamping blocks 14 are arranged opposite each other on the rotating frame 13, with the two clamping blocks 14 distributed vertically. The sliding direction of the clamping blocks 14 is parallel to the rotation axis of the rotating ring 4. A third driving member is mounted on the rotating frame 13 and is used to drive the two clamping blocks 14 closer together or further apart. To facilitate driving the two clamping blocks 14 closer together or further apart, the third driving member includes a third cylinder 20. The third cylinder 20 corresponds one-to-one with the clamping block 14 and is fixedly mounted on the rotating frame 13. The extension direction of the third cylinder 20 is parallel to the sliding direction of the clamping block 14, and the clamping block 14 is fixed to the piston rod of the corresponding third cylinder 20. In other embodiments, the third cylinder 20 can be replaced by an electric cylinder, an electric push rod, etc.

[0034] When it is necessary to clamp the heat sink workpiece, the third cylinder 20 is activated. The two third cylinders 20 drive the two clamping blocks 14 to move closer to each other, so that the two clamping blocks 14 can clamp and fix the heat sink workpiece. When it is necessary to release the heat sink workpiece, the third cylinder 20 is activated. The two third cylinders 20 drive the two clamping blocks 14 to move away from each other, so that the two clamping blocks 14 can be released from the heat sink workpiece.

[0035] By activating the second cylinder 18, the lifting rod 12 drives the rotating frame 13 and the clamping block 14 to rise, which helps the clamping block 14 to lift the heat sink workpiece, so that the heat sink workpiece is separated from the worktable 3. Then, by activating the second motor 19, the second motor 19 drives the rotating frame 13 to rotate the clamping block 14, which in turn rotates the heat sink workpiece. This allows the heat sink workpiece to be rotated by 90°, 180°, or other angles as needed to polish other surfaces of the heat sink workpiece, which is simple and convenient.

[0036] Reference Figure 2 and Figure 3 The connecting part 61 is rotatably sleeved on the rotating ring 4. The rotation axis of the connecting part 61 is perpendicular to the rotation axis of the rotating ring 4. The rotation axis of the connecting part 61 is perpendicular to the sliding direction of the sliding rod 7. The inner diameter of the connecting part 61 is larger than the outer diameter of the rotating ring 4 so that the connecting part 61 can rotate. There are two rotating shafts 21 fixed to the inner wall of the connecting part 61. The two rotating shafts 21 are rotatably inserted through the opposite sides of the rotating ring 4. The fixed column 2 is provided with an adjusting member 8 for adjusting the rotation of the connecting part 61.

[0037] Reference Figure 2For the convenience of adjusting the rotation of the connecting part 61, the adjusting part 8 comprises an adjusting ring 81 and an adjusting protrusion 82. The adjusting ring 81 is sleeved on the fixed column 2. Specifically, the inner wall of the adjusting ring 81 is fixedly connected with the outer wall of the fixed column 2 through a plurality of connecting rods 23. The adjusting ring 81 is concentrically arranged with the rotating ring 4. The adjusting ring 81 is located below the connecting part 61. The inner diameter of the adjusting ring 81 is larger than the outer diameter of the connecting part 61. There is a certain distance between the connecting rod 23 and the connecting part 61, so that the connecting part 61 will not interfere with the adjusting ring 81 and the connecting rod 23. The side of the adjusting ring 81 close to the workbench 3 is used for abutting against the side of the abutting part 62 away from the workbench 3.

[0038] With reference to Figure 2 The adjusting protrusion 82 is integrally formed on the side of the adjusting ring 81 close to the workbench 3. The side of the adjusting protrusion 82 close to the workbench 3 is an arc surface 10. The arc surface 10 protrudes outward in the direction away from the adjusting ring 81. The arc surface 10 is used for abutting against the side of the abutting part 62 away from the workbench 3. An adjusting inclined groove 9 is formed on the adjusting ring 81. The adjusting inclined groove 9 and the adjusting protrusion 82 are symmetrically arranged along the center of the adjusting ring 81. Specifically, the bottom wall of the adjusting inclined groove 9 is inclinedly arranged. The bottom wall of the adjusting inclined groove 9 away from the corresponding adjusting protrusion 82 is inclined downward. When the abutting part 62 at one end of the connecting part 61 abuts against the arc surface 10 of the adjusting protrusion 82, the abutting part 62 at the other end of the connecting part 61 abuts against the adjusting inclined groove 9. At this time, under the limitation of the adjusting protrusion 82 and the adjusting inclined groove 9, the connecting part 61 cannot rotate.

[0039] With reference to Figure 1 and Figure 2 For the convenience of the sliding abutment between the abutting part 62 and the adjusting protrusion 82, the side of the abutting part 62 close to the adjusting ring 81 is designed as a circular arc surface. The circular arc surface protrudes outward in the direction close to the adjusting ring 81.

[0040] When the clamping mechanism clamps and fixes the heat dissipation fin workpiece for polishing work, the abutting portions 62 at both ends of the connecting portion 61 abut against the upper surface of the adjusting ring 81, so that the connecting portion 61 remains in a horizontal state and cannot rotate, which is helpful for horizontal polishing; after the clamping mechanism changes the clamping position on the heat dissipation fin workpiece, the rotating member 5 drives the rotating ring 4 to synchronously rotate the connecting portion 61 and the abutting portion 62, when the abutting portion 62 at one end of the connecting portion 61 gradually approaches the adjusting protrusion 82, the abutting portion 62 at the other end gradually approaches the corresponding adjusting inclined groove 9, with the continuous rotation of the rotating ring 4, the circular arc surface of the abutting portion 62 gradually slides against the arc surface 10 of the adjusting protrusion 82, the adjusting protrusion 82 lifts the corresponding abutting portion 62 upward to rotate, thereby driving the connecting portion 61 to rotate on the rotating ring 4, the rotating ring 4 drives the abutting portion 62 at the other end to rotate downward and abut against the bottom wall of the adjusting inclined groove 9, at this time, the heat dissipation fin workpiece between the clamping mechanisms is inclined, which can make the debris on the surface of the heat dissipation fin workpiece fall off, with the continuous rotation of the rotating ring 4, the abutting portion 62 at one side is separated from the adjusting protrusion 82, and the abutting portion 62 at the other side is separated from the adjusting inclined groove 9, at this time, the connecting portion 61 returns to the horizontal state, so that the position clamped on the surface of the heat dissipation fin workpiece before can be polished, which ensures that the debris polished before does not easily affect the polishing quality after. Moreover, through the abutment of the abutting portion 62 at one end of the connecting portion 61 against the adjusting protrusion 82 and the abutment of the abutting portion 62 at the other end against the bottom wall of the adjusting inclined groove 9, the heat dissipation fin workpiece can be clamped and fixed in an inclined state, which is convenient for inclined surface polishing according to needs.

[0041] With reference to Figure 2 and Figure 3 , in order to quickly reset the abutting portion 62 after being separated from the adjusting protrusion 82, the torsional spring 22 is movably sleeved on the rotating shaft 21, one end of the torsional spring 22 is fixed on the outer wall of the rotating ring 4, and the other end is fixed on the inner wall of the connecting portion 61, when the torsional spring 22 is in a natural state, the connecting portion 61 is in a horizontal state. After the abutting portion 62 is separated from the adjusting protrusion 82, the deformed torsional spring 22 can quickly drive the connecting portion 61 to return to the horizontal state.

[0042] With reference to Figure 1 and Figure 2 , the arc surface 10 of the adjusting protrusion 82 close to the side of the workbench 3 includes a flat section 101 and an arc section 102, the arc section 102 is provided with two sections, the two arc sections 102 are located on the opposite sides of the flat section 101, the vertical distance from the flat section 101 to the workbench 3 is less than the vertical distance from the surface of the adjusting ring 81 to the workbench 3, one side of the arc section 102 is connected with the upper surface of the adjusting ring 81, and the other side is connected with the corresponding flat section 101. By providing the flat section 101 on the arc surface 10 of the adjusting protrusion 82, the stability of the abutting portion 62 in abutting against the adjusting protrusion 82 can be improved, the abutting area is enlarged, and the stability of the heat dissipation fin during inclined surface polishing is improved.

[0043] With reference to Figure 2 The width of the abutting portion 62 is less than the outer diameter of the rotating ring 4, the adjusting protrusions 82 are arranged along the circumferential direction of the adjusting ring 81, the adjusting inclined grooves 9 correspond to the adjusting protrusions 82 one by one, the protruding heights of the plurality of adjusting protrusions 82 increase in turn along the circumferential direction of the adjusting ring 81, and the depths of the adjusting inclined grooves 9 are designed according to the heights of the corresponding adjusting protrusions 82, so that when the abutting portion 62 at one end of the connecting portion 61 abuts against the flat section 101 of the adjusting protrusion 82, the abutting portion 62 at the other end abuts against the bottom wall of the corresponding adjusting inclined groove 9. In the embodiment of the present application, the adjusting protrusions 82 on the adjusting ring 81 are provided with two, the protruding heights of the adjusting protrusions 82 are designed to be different from each other, different inclination angles of the heat dissipation fin workpiece can be realized, and the polishing requirement of different inclination angles can be met. The protruding heights of the adjusting protrusions 82 are designed to increase in turn, which facilitates the operator to move the abutting portion 62 to the adjusting protrusion 82 at the appropriate height.

[0044] With reference to Figure 2 The side wall of the abutting portion 62 is provided with a cleaning brush 11, and the bristles of the cleaning brush 11 are used to abut against the surface of the adjusting protrusion 82 or the adjusting ring 81. Specifically, the cleaning brush 11 is located on the side of the abutting portion 62 close to the forward rotation direction of the rotating ring 4, so that when the rotating ring 4 drives the connecting portion 61 and the abutting portion 62 to rotate, the cleaning brush 11 first brushes off the debris on the adjusting ring 81 or the adjusting protrusion 82, and then the abutting portion 62 abuts against the adjusting ring 81 or the adjusting protrusion 82, thereby reducing the influence of the debris on the cooperation between the abutting portion 62 and the adjusting ring 81 or the abutting portion 62 and the adjusting protrusion 82.

[0045] With reference to Figure 1 The grinding machine further comprises a diamond grinding wheel 15 installed on the machine tool 1. The driving modes of the movement and rotation of the diamond grinding wheel 15 are both prior art, and will not be described in detail here. The diamond grinding wheel 15 is located above the workbench 3, and is used to polish the workpiece on the workbench 3. The diamond grinding wheel 15 has the advantages of extremely high hardness, stable grinding performance, and low processing heat. The grinding wheel of the present application adopts the diamond grinding wheel 15, which is helpful for efficient and high-precision polishing of the heat dissipation fin workpiece.

[0046] The implementation principle of the embodiment of the present application is that when in use, the heat dissipation fin workpiece to be polished is placed on the workbench 3, at this time, the abutting portions 62 at both ends of the connecting portion 61 are in abutment with the upper surface of the adjusting ring 81, the torsional spring 22 is in a natural state, the second cylinder 18 is started, the second cylinder 18 drives the lifting rod 12 to move the rotating frame 13 to align with the end of the heat dissipation fin workpiece, then the first cylinder 16 is started to drive the corresponding sliding rod 7 to drive the lifting rod 12 and the rotating frame 13 to approach the workbench 3, until the end of the heat dissipation fin workpiece enters between the two clamping blocks 14 on the rotating frame 13, then the third cylinder 20 is started, the third cylinder 20 drives the two clamping blocks 14 to approach each other, so as to clamp and fix the edge of the heat dissipation fin workpiece, at this time, the diamond grinding wheel 15 can be driven to polish the heat dissipation fin workpiece, and the workbench 3 supports the bottom of the heat dissipation fin workpiece to prevent the heat dissipation fin workpiece from deforming.

[0047] After the non-clamping area of the heat dissipation fin workpiece is polished, the third cylinder 20 is started, the third cylinder 20 drives the clamping blocks 14 to move away from the heat dissipation fin workpiece, the two clamping blocks 14 on the rotating frame 13 are separated from the heat dissipation fin workpiece, then the first cylinder 16 is started to drive the corresponding sliding rod 7 to drive the lifting rod 12 and the rotating frame 13 to move away from the workbench 3, and the rotating frame 13 is moved to the required position; then the first motor 51 is started, the first motor 51 drives the gear 52 to rotate, the gear 52 drives the gear ring 53 and the rotating ring 4 to rotate, the rotating ring 4 drives the connecting portion 61 and the abutting portion 62 to rotate synchronously, so that the rotating frame 13 is moved to the position aligned with the polished heat dissipation fin workpiece, and the abutting portions 62 at both ends of the connecting portion 61 are also in abutment with the upper surface of the adjusting ring 81, and the connecting portion 61 is in a horizontal state; then the first cylinder 16 is started, the first cylinder 16 drives the sliding rod 7 to drive the lifting rod 12 and the rotating frame 13 to approach the workbench 3, then the third cylinder 20 is started, so that the two clamping blocks 14 on the rotating frame 13 clamp and fix the polished area on the heat dissipation fin workpiece.
