DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0016] Such as Figures 1-3As shown in the figure, a processing fixture for a heat sink includes a frame 1. A servo motor 2 is provided on an outer wall of one side of the frame 1. An output end of the servo motor 2 penetrates through the frame 1 and is connected to a first rotating plate 3 at an end. A pair of limiting rods 4 are provided on a side of the first rotating plate 3 away from the servo motor 2. A second rotating plate 5 is slidably provided on the pair of limiting rods 4. A first telescopic cylinder 6 is provided on a side wall of the frame 1 opposite to the position of the servo motor 2. A telescopic end of the first telescopic cylinder 6 penetrates through the frame 1 and is rotatably connected to the second rotating plate 5. Two groups of fixing components capable of limiting the heat sink in the vertical direction are provided on opposite side walls of the first rotating plate 3 and the second rotating plate 5; Each group of the fixing components includes a fixing plate 8, a top plate 10, a second telescopic cylinder 11, a transmission plate 9 and a plurality of fixing bars 12. The fixing plate 8 and the top plate 10 are oppositely arranged on the first rotating plate 3 or the second rotating plate 5. The second telescopic cylinder 11 is provided on a side of the top plate 10 away from the fixing plate 8. A telescopic end of the second telescopic cylinder 11 penetrates through the top plate 10 and the telescopic end is connected to the transmission plate 9. The plurality of fixing bars 12 are provided on the transmission plate 9. A groove is formed in the fixing plate 8; An installation groove is formed at a central position on a side of the second rotating plate 5 close to the first telescopic cylinder 6. A bearing 7 is connected to a telescopic end of the first telescopic cylinder 6. An outer ring of the bearing 7 is connected to a side wall of the installation groove.

[0017] The detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process, which are as follows:

[0018] In the present utility model, the servo motor 2, the first telescopic cylinder 6 and the second telescopic cylinder 11 are all connected to an external electronic control system through wires. The above devices and connection methods are all prior arts and will not be elaborated here too much.

[0019] According to the attached instructions Figures 1-3It can be seen that when the utility model is in use, the frame 1 is installed on a support component such as a workbench, and then the heat sink is placed between two groups of fixing components arranged on the opposite sides of the first rotating plate 3 and the second rotating plate 5. The first telescopic cylinder 6 arranged on the side wall of the frame 1 is started, and the telescopic end of the first telescopic cylinder 6 drives the second rotating plate 5 connected in a rotating manner to move towards the first rotating plate 3. The second moving plate slides on a pair of limiting rods 4, so that the pair of limiting rods 4 limit the second rotating plate 5. The two groups of fixing components abut against the heat sink to limit the heat sink in the horizontal direction, and then the heat sink is limited in the vertical direction by the two groups of fixing components. After the fixing is completed, one surface of the heat sink is processed. When the processing is completed, the servo motor 2 arranged on the frame 1 is started, and the servo motor 2 drives the first rotating plate 3 to flip 180 degrees. The first rotating plate 3 drives a pair of limiting rods 4 to rotate, and a pair of limiting rods 4 drives the second rotating plate 5 to rotate. Since the second rotating plate 5 and the telescopic end of the first telescopic cylinder 6 are connected in a rotating manner, the first telescopic cylinder 6 does not rotate when the second rotating plate 5 rotates. When the first rotating plate 3 and the second rotating plate 5 rotate, they drive the two groups of fixing components to rotate, and the two groups of fixing components drive the heat sink to rotate, thereby realizing the flipping of the heat sink; by driving the second rotating plate 5 to move towards the first rotating plate 3 by the first telescopic cylinder 6, the fixing components on the first rotating plate 3 and the second rotating plate 5 limit the heat sink in the horizontal direction, and then the heat sink is limited in the vertical direction by the two groups of fixing components. The servo motor 2 drives the heat sink to flip, and when switching the processing surface of the heat sink, there is no need to disassemble and assemble the heat sink again, the operation is convenient, the personnel are labor-saving, and the processing efficiency is improved.

[0020] There is a possible implementation. When using the fixing components to fix the heat sink, the bottom body part of the heat sink is aligned with the groove position opened on the fixing plate 8, and the gaps between the heat dissipation fins are aligned with the positions of the plurality of fixing strips 12. When the second rotating plate 5 moves towards the first rotating plate 3, the bottom body part of the heat sink is installed in a pair of grooves, and the fixing strips 12 on both sides are inserted into the heat dissipation fins. The second telescopic cylinder 11 arranged on the top plate 10 is started, and the telescopic end of the second telescopic rod drives the connected transmission plate 9 to move towards the fixing plate 8. The fixing plate 8 drives the connected plurality of fixing strips 12 to move, so that the plurality of fixing strips 12 and the fixing plate 8 cooperate to limit the heat sink in the vertical direction. When the servo motor 2 rotates, it rotates 180 degrees repeatedly and alternately, thereby preventing the connection line or pipe of the second telescopic cylinder 11 from being wound.

[0021] There is a possible implementation. An installation groove is opened at the center position on the side of the second rotating plate 5 close to the first telescopic cylinder 6. The telescopic end of the first telescopic cylinder 6 is connected with a bearing 7. The inner ring of the bearing 7 is connected with the telescopic end of the first telescopic cylinder 6, and the outer ring of the bearing 7 is connected with the side wall of the installation groove, so that the first telescopic cylinder 6 does not rotate when the second rotating plate 5 rotates.
