Two abutting portions 62 are arranged, and the two abutting portions 62 are symmetrically fixed on opposite sides of the connecting portion 61. The abutting portion 62 extends in a direction away from the connecting portion 61. Specifically, the length of the abutting portion 62 is direction is perpendicular to the axial direction of the connecting portion 61; sliding rods 7 are slidably inserted into the abutting portions 62 on opposite sides, the sliding direction of the sliding rod 7 is perpendicular to the rotation axis of the rotating ring 4, the sliding direction of the sliding rod 7 is parallel to the arrangement direction of the two abutting portions 62, the sliding direction of the sliding rod 7 is parallel to the length direction of the corresponding abutting portion 62, the distance between the sliding rods 7 on both sides and one end away from each other is greater than the diameter of the workbench 3, and a sliding member is provided in the abutting portion 62 for driving the sliding rod 7 to slide toward or away from the connecting portion 61, and a clamping mechanism is provided on the sliding rod 7 for clamping the end of the workpiece.

[0024] When in use, the heat sink workpiece to be polished is placed on the workbench 3, and the corresponding sliding rod 7 is driven by the sliding member to drive the clamping mechanism close to the workbench 3, and the clamping mechanism gradually approaches the heat sink workpiece on the workbench 3, and then the corresponding end of the heat sink workpiece is clamped by the clamping mechanism, and the heat sink workpiece can be polished at this time; after the non-clamping area of ​​the heat sink workpiece is polished, the heat sink workpiece is released by the clamping mechanism, and then the corresponding sliding rod 7 is driven by the sliding member to drive the clamping mechanism away from the workbench 3, so that the clamping mechanism is separated from the heat sink workpiece, and then the rotating ring 4 is driven by the rotating member 5 to drive the mounting plate 6 and the sliding rod 7 to rotate horizontally, and the clamping mechanism is moved to the position where the polishing of the heat sink workpiece is completed, and then the corresponding sliding rod 7 is driven by the sliding member to drive the clamping mechanism close to the workbench 3, so that the clamping mechanism clamps the polished end of the heat sink workpiece, and then the previous clamping position of the heat sink workpiece can be polished, which helps to ensure the uniformity of the size of the heat sink after polishing. At the same time, the sliding rod 7 slides toward or away from the connecting portion 61, can clamp heat sink workpieces of different sizes, and can also drive the heat sink workpiece to move or rotate in the horizontal direction, so as to adjust the heat sink position according to grinding needs.

[0025] Reference Figure 2 and Figure 3 In order to drive the rotating ring 4 to drive the connecting part 61 to rotate, the rotating member 5 includes a first motor 51, a gear 52 and a gear ring 53. The first motor 51 is fixedly installed on the outer wall of the fixed column 2. The first motor 51 is located between the workbench 3 and the rotating ring 4. The gear 52 is coaxially fixed on the output shaft of the first motor 51. The gear ring 53 is fixedly sleeved on the outer wall of the rotating ring 4. The gear ring 53 is located above the connecting part 61 and is a certain distance away. The gear 52 is meshed with the gear ring 53.

[0026] When it is necessary to drive the rotating ring 4 to rotate, the first motor 51 is started, the first motor 51 drives the gear 52 to rotate, the gear 52 drives the ring gear 53 to rotate, and the ring gear 53 drives the rotating ring 4 to rotate the rotating ring 4, which helps to rotate the clamping mechanism on the sliding rod 7 to the required angle of the workbench 3 as needed.

[0027] Reference Figure 2 In order to facilitate driving the sliding rod 7 to drive the clamping mechanism to slide in a direction close to or away from the workbench 3, the sliding member includes a first cylinder 16, which is fixedly installed in the abutment portion 62, and the extension direction of the first cylinder 16 is parallel to the sliding direction of the corresponding sliding rod 7. The sliding rod 7 is fixed to the piston rod of the corresponding first cylinder 16. By starting the first cylinder 16, the first cylinder 16 drives the corresponding sliding rod 7 to slide, thereby driving the corresponding clamping mechanism to slide in a direction close to or away from the workbench 3. In other embodiments, the first cylinder 16 can be replaced by an electric cylinder, an electric push rod, etc.

[0028] Reference Figure 1 and Figure 2 In order to facilitate the clamping and fixing of the heat sink 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 slidably arranged at the end of the corresponding sliding rod 7 away from the abutment portion 62. The sliding direction of the lifting rod 12 is parallel to the rotation axis of the rotating ring 4. Specifically, a slider (not shown in the figure) is fixed to the end of the sliding rod 7 away from the abutment portion 62. The lifting rod 12 is provided with a sliding groove 17 that slidably cooperates with the corresponding slider, 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.

[0029] Reference 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 end of the lifting rod 12 away from the workbench 3 is fixedly connected to 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.

[0030] Reference Figure 1 and Figure 2 The rotating frame 13 is U-shaped, and the rotating frame 13 is rotatably arranged on the side of the corresponding lifting rod 12 close to the workbench 3. The opening of the rotating frame 13 is arranged in the direction of the workbench 3, so that the workpiece can be easily moved 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 mounted on the lifting rod 12, and the second motor 19 is a reduction motor. 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 drive motor, a stepping motor, etc.

[0031] Reference Figure 1 and Figure 2The clamping block 14 is slidably arranged on the rotating frame 13. Two clamping blocks 14 are arranged on the rotating frame 13 relatively. The two clamping blocks 14 are distributed up and down. The sliding direction of the clamping blocks 14 is parallel to the rotation axis of the rotating ring 4. The third driving member is arranged on the rotating frame 13. The third driving member is used to drive the two clamping blocks 14 to move closer to or away from each other. In order to facilitate driving the two clamping blocks 14 to move closer to or away from each other, the third driving member includes a third cylinder 20. The third cylinder 20 corresponds to the clamping block 14 one by one. The third cylinder 20 is fixedly installed on the rotating frame 13. The extension direction of the third cylinder 20 is parallel to the sliding direction of the clamping block 14. The clamping block 14 is fixed to the piston rod corresponding to the third cylinder 20. In other embodiments, the third cylinder 20 can be replaced by an electric cylinder, an electric push rod, etc.

[0032] When it is necessary to clamp the heat sink workpiece, the third cylinder 20 is started, and the two third cylinders 20 drive the two clamping blocks 14 to approach each other, thereby facilitating the two clamping blocks 14 to clamp and fix the heat sink workpiece. When it is necessary to release the heat sink workpiece, the third cylinder 20 is started, and the two third cylinders 20 drive the two clamping blocks 14 to move away from each other, thereby facilitating the two clamping blocks 14 to separate from the heat sink workpiece.

[0033] By starting the second cylinder 18 to drive the lifting rod 12 to drive the rotating frame 13 and the clamping block 14 to rise, it is helpful for the clamping block 14 to drive the heat sink workpiece to rise, so that the heat sink workpiece is separated from the workbench 3. Then, by starting the second motor 19, the second motor 19 drives the rotating frame 13 to drive the clamping block 14 to rotate, so that the clamping block 14 drives the heat sink workpiece to rotate, so that the heat sink workpiece can be rotated 90°, 180°, etc. as needed to grind other surfaces of the heat sink workpiece, which is simple and convenient.

[0034] Reference Figure 2 and Figure 3 The connecting part 61 is rotatably sleeved on the rotating ring 4, the rotating axis of the connecting part 61 is perpendicular to the rotating axis of the rotating ring 4, the rotating 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, and two rotating shafts 21 are relatively fixed to the inner wall of the connecting part 61, and the two rotating shafts 21 are rotatably penetrated on opposite sides of the rotating ring 4, and an adjusting member 8 for adjusting the rotation of the connecting part 61 is provided on the fixed column 2.

[0035] Reference Figure 2To facilitate the rotation of the adjustable connecting portion 61, the adjusting member 8 includes 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 to 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 portion 61. The inner diameter of the adjusting ring 81 is greater than the outer diameter of the connecting portion 61. There is a certain distance between the connecting rod 23 and the connecting portion 61 so that the connecting portion 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 to abut against the side of the abutting portion 62 away from the workbench 3.

[0036] Reference Figure 2 The adjusting protrusion 82 is integrally formed on the side of the adjusting ring 81 close to the workbench 3, and the side of the adjusting protrusion 82 close to the workbench 3 is an arc surface 10, which protrudes outward in the direction away from the adjusting ring 81, and the arc surface 10 is used to abut against the side of the abutting portion 62 away from the workbench 3; an adjusting bevel 9 is provided on the adjusting ring 81, and the adjusting bevel 9 and the adjusting protrusion 82 are symmetrically arranged along the center of the circle of the adjusting ring 81. Specifically, the bottom wall of the adjusting bevel 9 is inclined, and the bottom wall of the adjusting bevel 9 away from the corresponding adjusting protrusion 82 is inclined downward. When the abutting portion 62 at one end of the connecting portion 61 abuts against the arc surface 10 of the adjusting protrusion 82, the abutting portion 62 at the other end of the connecting portion 61 abuts against the adjusting bevel 9. At this time, under the restriction of the adjusting protrusion 82 and the adjusting bevel 9, the connecting portion 61 cannot rotate.

[0037] Reference Figure 1 and Figure 2 In order to facilitate the sliding contact between the abutting portion 62 and the adjusting protrusion 82 , a surface of the abutting portion 62 close to the adjusting ring 81 is designed as an arc surface, and the arc surface is convex toward the direction close to the adjusting ring 81 .

[0038] When the clamping mechanism clamps and fixes the heat sink workpiece for grinding, 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 horizontal and does not rotate, which is conducive to horizontal grinding. When the clamping mechanism changes the clamping position on the heat sink workpiece, the rotating ring 4 is driven by the rotating member 5 to drive the connecting portion 61 and the abutting portion 62 to rotate synchronously. 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. As the rotating ring 4 continues to rotate, the arc surface of the abutting portion 62 gradually aligns with the arc surface 10 of the adjusting protrusion 82. When relative sliding occurs, the adjusting protrusion 82 will lift the corresponding abutting portion 62 to rotate upward, thereby driving the connecting portion 61 to rotate on the rotating ring 4, and 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 chute 9. At this time, the heat sink workpiece between the clamping mechanism is tilted, which can make the debris previously polished on the surface of the heat sink workpiece fall off. As the rotating ring 4 continues to rotate, the abutting portion 62 on one side is separated from the adjusting protrusion 82, and the abutting portion 62 on the other side is separated from the adjusting chute 9. At this time, the connecting portion 61 returns to a horizontal state, and the previously clamped position on the surface of the heat sink workpiece can be polished, ensuring that the debris previously polished is not easy to affect the subsequent polishing quality. In addition, by abutting the abutting portion 62 at one end of the connecting portion 61 with the adjusting protrusion 82, and the abutting portion 62 at the other end with the bottom wall of the adjusting chute 9, the heat sink workpiece can be clamped and fixed in an inclined state, which is convenient for inclined surface polishing as needed.

[0039] Reference Figure 2 and Figure 3 In order to facilitate the quick reset of the abutting portion 62 after it is separated from the adjusting protrusion 82, a torsion spring 22 is movably sleeved on the rotating shaft 21, one end of the torsion 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 torsion spring 22 is in a natural state, the connecting portion 61 is in a horizontal state. When the abutting portion 62 is separated from the adjusting protrusion 82, the deformed torsion spring 22 can quickly drive the connecting portion 61 to reset to a horizontal state.

[0040] Reference Figure 1 and Figure 2 The arc surface 10 of the adjusting protrusion 82 near the workbench 3 includes a straight section 101 and an arc section 102. The arc section 102 is provided with two sections. The two arc sections 102 are located on opposite sides of the straight section 101. The vertical distance from the straight section 101 to the workbench 3 is smaller 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 to the upper surface of the adjusting ring 81, and the other side is connected to the corresponding straight section 101. By providing the straight section 101 on the arc surface 10 of the adjusting protrusion 82, the stability of the arc surface of the abutting portion 62 abutting against the adjusting protrusion 82 can be improved, the abutting area can be expanded, and the stability of the heat sink during the bevel grinding can be improved.

[0041] Reference Figure 2 , the width of the abutment portion 62 is smaller than the outer diameter of the rotating ring 4, a plurality of adjusting protrusions 82 are provided along the circumferential direction of the adjusting ring 81, the adjusting bevel grooves 9 correspond to the adjusting protrusions 82 one by one, the protruding heights of the plurality of adjusting protrusions 82 are increased successively along the circumferential direction of the adjusting ring 81, and the depth of the adjusting bevel grooves 9 is designed according to the height of the corresponding adjusting protrusions 82, so as to ensure that when the abutment portion 62 at one end of the connecting portion 61 abuts against the straight section 101 of the adjusting protrusion 82, the abutment portion 62 at the other end abuts against the bottom wall of the corresponding adjusting bevel groove 9. In the embodiment of the present invention, two adjusting protrusions 82 are provided on the adjusting ring 81, and the protruding heights of the adjusting protrusions 82 are designed to be different from each other, so as to realize different inclination angles of the heat sink workpiece, and thus be suitable for the grinding requirements of different inclination angles. The protruding heights of the adjusting protrusions 82 are designed to increase successively, so that the operator can move the abutment portion 62 to the adjusting protrusion 82 of the appropriate height conveniently.

[0042] Reference Figure 2 A cleaning brush 11 is provided on the side wall of the abutting portion 62, 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 rotating ring 4 in the rotational forward direction, 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 the abutting portion 62 then abuts against the adjusting ring 81 or the adjusting protrusion 82, thereby reducing the influence of the debris on the mutual cooperation between the abutting portion 62 and the adjusting ring 81 or between the abutting portion 62 and the adjusting protrusion 82.

[0043] Reference Figure 1 The grinding machine further includes a diamond grinding wheel 15 mounted on the machine tool 1. The driving modes of the movement and rotation of the diamond grinding wheel 15 are all 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 grind the workpiece on the workbench 3. The diamond grinding wheel 15 has the advantages of extremely high hardness, stable grinding performance, low processing heat, etc. The grinding wheel of the present invention uses the diamond grinding wheel 15, which is helpful for high-efficiency and high-precision grinding of the heat sink workpiece.

[0044] The implementation principle of the embodiment of the present invention is as follows: when in use, the heat sink workpiece to be polished is placed on the workbench 3, at this time, the abutting parts 62 at both ends of the connecting part 61 are in abutment with the upper surface of the adjusting ring 81, the torsion 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 sink workpiece, and 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 sink workpiece enters between the two clamping blocks 14 on the rotating frame 13, and 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 sink workpiece, and at this time the diamond grinding wheel 15 can be driven to polish the heat sink workpiece, and the workbench 3 supports the bottom of the heat sink workpiece to prevent the heat sink workpiece from deformation.

[0045] After the non-clamping area of ​​the heat sink workpiece is polished, the third cylinder 20 is started, and the third cylinder 20 drives the clamping block 14 away from the heat sink workpiece, and the two clamping blocks 14 on the rotating frame 13 are separated from the heat sink workpiece, and 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 away from the workbench 3, and move the rotating frame 13 to the desired position; then the first motor 51 is started, and the first motor 51 drives the gear 52 to rotate, and the gear 52 drives the gear ring 53 and the rotating ring 4 to rotate, and the rotating frame 13 is rotated. The movable ring 4 drives the connecting part 61 and the abutting part 62 to rotate synchronously, so that the rotating frame 13 moves to the position aligned with the polished heat sink workpiece, and the abutting parts 62 at both ends of the connecting part 61 also abut against the upper surface of the adjusting ring 81, and the connecting part 61 is in a horizontal state; then the first cylinder 16 is started, and 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, and then the third cylinder 20 is started, so that the two clamping blocks 14 on the rotating frame 13 clamp the polished area on the fixed heat sink workpiece.

[0046] Then, the second cylinder 18 is started, and the second cylinder 18 drives the lifting rod 12 to drive the rotating frame 13 to rise, so that the heat sink workpiece is separated from the workbench 3; then the first motor 51 is started, and the first motor 51 drives the gear 52 to rotate, and the gear 52 drives the gear ring 53 and the rotating ring 4 to rotate, and the rotating ring 4 drives the connecting part 61 and the abutting part 62 to rotate synchronously, so that the abutting part 62 at one end of the connecting part 61 gradually approaches the adjusting protrusion 82, and the abutting part 62 at the other end gradually approaches the corresponding adjusting inclined groove 9. As the rotating ring 4 continues to rotate, the adjusting protrusion 82 will lift the corresponding abutment 62 to rotate upward, thereby driving the connection part 61 to rotate on the rotating ring 4, causing the torsion spring 22 to deform, and the rotating ring 4 drives the abutment 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 sink workpiece between the clamping mechanisms at both ends is tilted, which can make the debris previously polished on the surface of the heat sink workpiece fall off. As the rotating ring 4 continues to rotate, the abutment 62 on one side is separated from the adjusting protrusion 82, and the abutment 62 on the other side is separated from the adjusting inclined groove 9. At this time, the connection part 61 returns to a horizontal state.

[0047] Then, the second cylinder 18 is started, and the second cylinder 18 drives the lifting rod 12 to drive the rotating frame 13 to descend, so that the heat sink workpiece abuts against the workbench 3. The workbench 3 supports the heat sink workpiece, and the diamond grinding wheel 15 can be driven to grind the previously clamped position on the surface of the heat sink workpiece, thereby helping to ensure the uniformity of the size of the heat sink after grinding.

[0048] When it is necessary to perform bevel grinding on the heat sink workpiece, the abutment portion 62 at one end of the connecting portion 61 is moved to abut against the straight section 101 on the arc surface 10 of the adjusting protrusion 82 at the appropriate position, and the abutment portion 62 at the other end abuts against the bottom wall of the corresponding adjusting bevel groove 9 to achieve the inclination of the heat sink workpiece, and the bevel grinding of the heat sink workpiece can be performed by the diamond grinding wheel 15.

[0049] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
