Technical Field

[0001] The utility model relates to the field of heat sink processing, and more specifically, to a heat sink processing device. Background Art

[0002] In a mobile phone wireless charger with a power greater than or equal to 50W, due to the large charging power, a heat sink needs to be installed inside it to cooperate with a fan to cool the wireless charger. Therefore, a heat sink processing device is required to open holes in the heat sink so as to complete the installation inside the wireless charger.

[0003] Chinese Patent Grant Publication No.: CN220515466U provides a heat sink hole-opening device. This patent includes a hole-opening device base, on which a connecting support column is arranged. The connecting support column is welded to the hole-opening device base. At the end of the connecting support column far away from the hole-opening device base, there is a bearing support bottom plate, and the bearing support bottom plate is bolted to the connecting support column. It also includes a through hole, which is opened on the bearing support bottom plate and is integrally formed with the bearing support bottom plate.

[0004] However, in the above patent, when clamping and fixing the heat sink, due to the relatively simple clamping and fixing structure, when clamping a heat sink with a polygonal structure, the end of the clamping and fixing structure cannot closely and effectively fit with the convex part of the heat sink, so the clamping of the heat sink is not stable enough, and then the problem of heat sink offset occurs when opening holes in the heat sink, which is inconvenient and has limitations in use.

[0006] Aiming at the problems existing in the prior art, the purpose of the utility model is to provide a heat sink processing device to solve the problems put forward in the above background art.

[0008] To solve the above problems, the utility model adopts the following technical solutions.

[0009] A heat sink processing device includes a base and a mounting plate. Above the mounting plate, a round table is fixedly connected. Above the round table, a first rotating ring is rotatably connected. Above the first rotating ring, a rotating plate is rotatably connected. Inside the rotating plate, a sliding groove and a movable groove are opened.

[0019] 3. Beneficial effects

[0020] Compared with the prior art, the advantages of the present utility model are as follows:

[0021] (1) In this solution, when the four square blocks approach each other, the fourth rotating block on one side of the square block will come into contact with the heat sink first. If there are protruding structures on the outside of the heat sink, the fourth rotating block will rotate. If the protruding structure on the heat sink is relatively large, the third rotating block and the second rotating block will rotate simultaneously. Subsequently, the outside of the fourth rotating block will be rotated until it is in close contact with the protruding part on the outside of the heat sink. Through this design, when clamping a heat sink with a polygonal structure, the protruding parts on its outer wall can also be effectively squeezed and clamped, thereby improving the stability when clamping a heat sink with a polygonal structure.

[0022] (2) In this solution, if the heat sink in the frustum is of a polygonal structure, after the fourth rotating blocks on one side of the two square blocks that approach the heat sink first touch the heat sink and complete the extrusion on both sides of it, the support rod will rotate by a certain angle. Subsequently, the fourth rotating blocks on one side of the other two square blocks touch the heat sink and complete the extrusion on the other two sides of it. By the support rod rotating by a certain angle, it can be avoided that after the outer sides of the fourth rotating blocks on both sides clamp the heat sink by extrusion, the fourth rotating blocks on the other two sides cannot touch the heat sink, further enhancing the stability of clamping a heat sink with a polygonal structure.

[0023] (3) In this solution, during the process of the drill bit drilling holes in the heat sink, the user can start the fan, and the suction force generated by the fan will suck away the debris generated during drilling. After the heat sink is drilled, there is no need for the staff to perform secondary processing and cleaning on the drilled heat sink, improving the convenience of this device during use.

[0035] Embodiment 1:

[0036] Please refer to Figures 1-6, a heat sink processing device, including a base 1 and a mounting plate 15. Above the mounting plate 15 is fixedly connected with a frustum 16. Above the frustum 16 is rotatably connected with a first rotating ring 17. Above the first rotating ring 17 is rotatably connected with a rotating plate 18. Inside the rotating plate 18 are provided with a chute 19 and a movable groove 2. Two chutes 19 are opened above the rotating plate 18, and the other two chutes 19 are opened below the rotating plate 18. The chute 19 and the movable groove 2 are communicated. Inside the four movable grooves 2 are slidably connected with square blocks 21. Outside the four square blocks 21 are fixedly connected with limit blocks 22. The four limit blocks 22 slide inside the four chutes 19 respectively. Above the rotating plate 18 is rotatably connected with a second rotating ring 27. The first rotating ring 17 and the second rotating ring 27 are both provided with limit grooves 28. The four limit blocks 22 slide inside the four limit grooves 28 respectively. The limit groove 28 and the chute 19 are communicated. One side of the square block 21 is rotatably connected with a first rotating block 23. One side of the first rotating block 23 is rotatably connected with a second rotating block 24. One side of the two second rotating blocks 24 is rotatably connected with a third rotating block 25. One side of the four third rotating blocks 25 is rotatably connected with a fourth rotating block 26.

[0037] In this embodiment, when the first rotating ring 17 rotates, the two limit grooves 28 opened in the first rotating ring 17 will squeeze the limit blocks 22 inside it. Because the limit groove 28 has a certain inclined chamfer, when the limit block 22 is squeezed by the inner wall of the limit groove 28, the two square blocks 21 will slide inside the movable groove 2. Similarly, when the second rotating ring 27 rotates, the limit groove 28 opened in the second rotating ring 27 will also squeeze the limit blocks 22 inside it, and then the other two square blocks 21 will slide inside the other two movable grooves 2. By the mutual approach of the ends of the four square blocks 21, the purpose of clamping the heat sink inside the frustum 16 is achieved. When the four square blocks 21 approach each other, the fourth rotating block 26 on one side of the square block 21 will first come into contact with the heat sink. If there is a convex structure on the outside of the heat sink, the fourth rotating block 26 will rotate. If the volume of the convex structure of the heat sink is large, the third rotating block 25 and the second rotating block 24 will rotate simultaneously, and then the outside of the fourth rotating block 26 will be rotated until it is in close fit with the convex part on the outside of the heat sink.

[0038] Embodiment 2:

[0039] Please refer to Figures 1-6, a screw rod 29 is rotatably connected to the outside of the frustum 16. A handle 3 is fixedly connected to one end of the screw rod 29 located on the frustum 16. A moving block 31 is threadedly connected to the outer wall of the screw rod 29. The moving block 31 is slidably connected to the inside of the frustum 16. A support rod 32 is rotatably connected above the moving block 31. Both ends of the support rod 32 are rotatably connected to a connecting rod 33. The two connecting rods 33 are respectively located above and below the support rod 32. One end of the connecting rod 33 located above the support rod 32 is rotatably connected to the second rotating ring 27. One end of the connecting rod 33 located below the support rod 32 is rotatably connected to the outside of the first rotating ring 17. An electric cylinder 12 is fixedly connected above the base 1. The output end of the electric cylinder 12 is fixedly connected to the lower part of the mounting plate 15. A fixed seat 11 is fixedly connected above the base 1. One side of the mounting plate 15 is slidably connected to one side of the fixed seat 11. A lighting lamp 14 is installed outside the fixed seat 11. A drill bit 13 is arranged above the fixed seat 11. A blower 34 is fixedly connected to the outside of the fixed seat 11. The output end of the blower 34 is fixedly communicated with a conduit 35.

[0040] In this embodiment, when the user rotates the handle 3 to drive the screw rod 29 to rotate, it will drive the moving block 31 to slide inside the frustum 16. When the moving block 31 moves towards the direction where the second rotating ring 27 is located, the two connecting rods 33 will respectively push the first rotating ring 17 and the second rotating ring 27, and cause the first rotating ring 17 and the second rotating ring 27 to rotate simultaneously, thereby driving the four square blocks 21 to approach each other. If the heat sink inside the frustum 16 is of a polygonal structure, after the fourth rotating blocks 26 on one side of the two square blocks 21 that first approach the heat sink touch the heat sink and complete the extrusion of its two sides, the support rod 32 will rotate by a certain angle. Subsequently, the fourth rotating blocks 26 on one side of the other two square blocks 21 touch the heat sink and complete the extrusion of its other two sides. By the support rod 32 rotating by a certain angle, it can avoid the situation that when the outer sides of the fourth rotating blocks 26 on both sides clamp the heat sink, the fourth rotating blocks 26 on the other two sides cannot touch the heat sink, thereby enhancing the stability of clamping the polygonal structure heat sink.

[0041] The working principle of the present utility model is as follows: If it is necessary to punch holes in the heat sink, the user can place the heat sink to be punched inside the frustum 16, and then rotate the handle 3 to drive the screw rod 29 to rotate. When the user rotates the handle 3 to drive the screw rod 29 to rotate, it will drive the moving block 31 to slide inside the frustum 16. When the moving block 31 moves towards the direction where the second rotating ring 27 is located, the two connecting rods 33 will respectively push the first rotating ring 17 and the second rotating ring 27, and cause the first rotating ring 17 and the second rotating ring 27 to rotate simultaneously, thereby driving the four square blocks 21 to approach each other. If the heat sink inside the frustum 16 is a polygonal structure, after the fourth rotating blocks 26 on one side of the two square blocks 21 that first approach the heat sink touch the heat sink and complete the extrusion of its two sides, the support rod 32 will rotate at a certain angle. Subsequently, the fourth rotating blocks 26 on one side of the other two square blocks 21 touch the heat sink and complete the extrusion of its other two sides. When the four square blocks 21 approach each other, the fourth rotating blocks 26 on one side of the square blocks 21 will first come into contact with the heat sink. If there are protruding structures on the outside of the heat sink, the fourth rotating blocks 26 will rotate. If the volume of the protruding structure of the heat sink is relatively large, the third rotating block 25 and the second rotating block 24 will rotate simultaneously, and then rotate the outside of the fourth rotating block 26 until it fits tightly with the protruding part on the outside of the heat sink. Subsequently, start the electric cylinder 12, the output end of the electric cylinder 12 extends, and the drill bit 13 can punch holes in the heat sink inside the frustum 16. During the process of the drill bit 13 punching holes in the heat sink, the user can start the blower 34, and the suction force generated by the blower 34 will suck away the debris generated during the punching process.

Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its improved concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
