[0026] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0027] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0028] See also Figures 1 to 5 An embodiment of the utility model provides a heat sink assembly fixture, which includes: a base 1, a lifting component 2 and a clamping component 3.

[0029] In the embodiments of the present invention, please refer to Figure 1 , Figure 2 and Figure 3 A limiting groove 11 is provided on the base 1, and a mounting groove 13 is provided in the limiting groove 11. Both sides of the top of the base 1 are provided with movable grooves A12 connected to the limiting groove 11, and the inner bottom wall of the limiting groove 11 is provided with a movable groove B14 connected to the mounting groove 13. A metal sheet 15 is provided on one side of the base 1 close to the mounting frame 32, and the metal sheet 15 is located below the fixing frame 31.

[0030] It should be noted that: the base 1 is the main part of the fixture, the limiting groove 11 can be used to place the heat sink, and the mounting groove 13 is mainly used to place the metal block. Since the mounting groove 13 is located in the limiting groove 11, during the heat sink assembly work, the metal block must be placed in the mounting groove 13 first, and then the heat sink is placed in the limiting groove 11. After that, the threaded holes therebetween are aligned, and the heat sink and the metal block can be fixed and assembled with screws. The movable groove A12 can be used to adjust the position of the heat sink in the limiting groove 11 with fingers, and the movable groove B14 can be used to adjust the position of the metal block in the mounting groove 13 with fingers. The metal sheet 15 is located on one side of the base 1 to facilitate the adsorption of the magnet sheet 36 and to limit the mounting frame 32.

[0031] In the embodiments of the present invention, please refer to Figure 1 and Figure 4 The lifting component 2 is located in the installation groove 13, and the lifting component 2 includes a gear A21, a screw rod 22, a sleeve rod 23 and a placement plate 24. The gear A21 is provided on the inner bottom wall of the installation groove 13, and the top of the gear A21 is provided with a screw rod 22 that is fixedly connected. The screw rod 22 is sleeved with a sleeve rod 23 that is threadedly connected, and the top of the sleeve rod 23 is provided with a placement plate 24 that is fixedly connected. The lifting component 2 also includes a gear B25 and a knob 26. The inner wall of the installation groove 13 is provided with a gear B25 that meshes with the gear A21, and one side of the base 1 is provided with a knob 26 for driving the gear B25 to rotate.

[0032] It should be noted that: after the metal block is placed in the installation groove 13, the knob 26 can be rotated according to the size and height of the metal block to drive the gear B25 to rotate, and the gear B25 is used to drive the gear A21 to rotate. During the rotation process, the gear A21 can drive the screw rod 22 to rotate. When the screw rod 22 rotates, it can cooperate with the sleeve rod 23 to complete the lifting and lowering of the placement plate 24. By changing the direction of the knob 26, the up and down movement direction of the placement plate 24 is completed, so as to adjust the height of the metal block in the installation groove 13. After the top of the metal block is flush with the inner bottom wall of the limit groove 11, the knob 26 can be stopped, and then the heat sink can be placed in the limit groove 11, and subsequent assembly work can be carried out.

[0033] In the embodiments of the present invention, please refer to Figure 2 and Figure 5The clamping assembly 3 is located on the base 1, and the clamping assembly 3 includes a fixing frame 31, a mounting frame 32 and a rubber block 35. The fixing frame 31 is installed on one side of the base 1, and a mounting frame 32 rotatably connected to the fixing frame 31 is provided, and a rubber block 35 is provided on the inner top wall of the mounting frame 32. The clamping assembly 3 also includes a spring 33, a spring 34 and a magnet sheet 36. A spring 33 is provided at the connection between the mounting frame 32 and the fixing frame 31, a plurality of springs 34 are provided between the mounting frame 32 and the rubber block 35, and a magnet sheet 36 is provided on the mounting frame 32.

[0034] It should be noted that: before assembling, the mounting frame 32 is rotated, and the spring 33 is tightened at this time, so that the magnet sheet 36 is attached to the metal sheet 15 on the base 1, and the magnet sheet 36 is used to adsorb the metal sheet 15 to complete the limiting work of the mounting frame 32. After that, after the heat sink is placed in the limiting groove 11, the mounting frame 32 is manually rotated to separate the magnet sheet 36 from the metal sheet 15, and then the mounting frame 32 is released. At this time, the spring 33 rebounds and drives the mounting frame 32 to rotate, so that the mounting frame 32 rotates to the top of the limiting groove 11, and the rubber block 35 will be against the heat sink in the limiting groove 11, The heat sink is simply fixed, which is convenient for the staff to carry out subsequent assembly work.

[0035] The working principle of the heat sink assembly fixture provided by the utility model is as follows:

[0036] First, the base 1 is placed at the designated working position. Before assembling, the mounting frame 32 is rotated. At this time, the spring 33 is tightened, and the magnet sheet 36 is attached to the metal sheet 15 on the base 1. The magnet sheet 36 has an adsorption effect on the metal sheet 15 to complete the position limiting work of the mounting frame 32.

[0037] When assembling the heat sink, first put the metal block into the installation groove 13. After the metal block is put into the installation groove 13, according to the size and height of the metal block, the knob 26 can be turned to drive the gear B25 to rotate, and the gear B25 drives the gear A21 to rotate. During the rotation process, the gear A21 can drive the screw rod 22 to rotate. When the screw rod 22 rotates, it can cooperate with the sleeve rod 23 to complete the lifting and lowering of the placement plate 24. By changing the direction of the knob 26, the up and down movement direction of the placement plate 24 is completed, so as to adjust the height of the metal block in the installation groove 13. After the top of the metal block is flush with the inner bottom wall of the limiting groove 11, the knob 26 can be stopped. Then the staff can adjust the position of the metal block through the movable groove B14, and then the heat sink can be placed in the limiting groove 11;

[0038] After placing the heat sink into the limiting groove 11, the staff can use their fingers to adjust the position of the heat sink in the limiting groove 11 through the movable groove A12 to align the heat sink with the threaded hole of the metal block, and then manually rotate the mounting frame 32 to separate the magnet sheet 36 from the metal sheet 15, and then release the mounting frame 32. At this time, the spring 33 rebounds and drives the mounting frame 32 to rotate, so that the mounting frame 32 rotates to the top of the limiting groove 11. At this time, the rubber block 35 will rest on the heat sink in the limiting groove 11 to simply fix the heat sink, and then the heat sink and the metal block can be assembled.

[0039] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0040] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
