Description

Technical Field

[0001] This utility model belongs to the field of CPU heat dissipation module production technology, specifically relating to a CPU heat dissipation module production testing clamping fixture. Background Technology

[0002] The CPU, or Central Processing Unit, is one of the main components of an electronic computer and a core part of the computer. Its main functions are to interpret computer instructions and process data in computer software. The CPU is the core component in a computer responsible for reading instructions, decoding instructions, and executing instructions.

[0003] For example, Chinese utility model patent CN221475070U discloses a CPU heat dissipation module production and testing clamping fixture. This utility model uses two cylinders to move a clamping tripod on two sliding grooves, which in turn moves a rack and pinion, causing the transmission gears to rotate and thus clamping the CPU heat dissipation module with suction cups. The multiple suction cups provide stable clamping of the CPU heat dissipation module. This utility model also uses a dual-head motor to rotate a rotating rod in different directions, causing the second and first bevel gears to rotate, which in turn rotates a threaded rod. The threaded rod then moves the threaded mounting bracket up and down. This solves the problem of manual disassembly and assembly required for height adjustment.

[0004] However, the applicant found that the aforementioned solution still had shortcomings. On the one hand, the solution clamped and fixed the CPU heat dissipation module from both sides using clamping components. However, the two sides of the CPU heat dissipation module are its thin outer shell, not its fixed parts. Excessive clamping force can easily cause deformation of the outer shell and damage to the CPU heat dissipation module. On the other hand, during the testing process, it is sometimes necessary to remove the outer shell to observe the stability of the internal components of the CPU heat dissipation module. However, the aforementioned solution limits the movement by clamping the two sides, which makes it impossible to properly clamp the CPU heat dissipation module without the outer shell, which is quite inconvenient.

[0005] To address the aforementioned issues, this application proposes a CPU heat dissipation module production testing clamping fixture.

[0006] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0037] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0038] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0039] The first and second directions described in this embodiment correspond to the horizontal and vertical directions within a plane.

[0040] Please see Figures 1-5 This utility model provides the following technical solution: a CPU heat dissipation module production and testing clamping fixture for clamping and fixing a CPU heat dissipation module 22 with fastening bolts 23, comprising a main body plate 1, a positioning component, and an adjustment component. The positioning component, in conjunction with the fastening bolts 23, is used for the detachable positioning and fixing of the CPU heat dissipation module 22, while the adjustment component can adjust the movement of the positioning component in at least one direction, thereby positioning and clamping the CPU heat dissipation module 22.

[0041] Specifically, the main body plate 1 has a raised center and an inner cavity 16; two positioning components are set on the main body plate 1 to limit and fix the CPU heat dissipation module 22; an adjustment component is set in the inner cavity 16 and connected to the positioning components, and the adjustment component can move horizontally to change the distance between the two positioning components.

[0042] Preferably, by Figure 1 and Figure 4 As shown, in this embodiment, a pair of guide slots 7 are provided on the main body plate 1; the guide slots are elongated holes, which are opened along the first direction (defined as horizontal in this embodiment), and the two elongated holes are spaced a certain distance apart and are arranged in parallel.

[0043] The adjustment assembly includes a positive and negative threaded rod 20 rotatably disposed in the inner cavity 16. One end of the positive and negative threaded rod 20 is provided with a hand-tightening knob 8. Sealing plates 24 are provided at both ends of the inner cavity 16. The positive and negative threaded rod 20 is rotatably disposed on the sealing plates 24 through bearings. The positive and negative threaded rod 20 realizes rotation along its own axis. Due to the setting of positive and negative threads, the two adjustment parts threadedly connected to the positive and negative threads can move closer to each other or further away from each other.

[0044] Both the positive and negative threads of the threaded rod 20 are threaded with movable plates 19. The two movable plates 19 can be brought closer or further apart by the threaded rod 20. When the hand knob 8 is turned clockwise, the clockwise rotation of the threaded rod 20 forces the two movable plates 19 closer together. Specifically, the movable plates 19 have threaded holes with internal threads, which are threaded to the threaded rod 20. In this embodiment, the movable plates 19 are positioned at the aforementioned adjustment part.

[0045] Preferably, by Figure 1 and Figure 4 As shown, in this embodiment, the positioning assembly includes two second slide rails 6 movably mounted on the main body plate 1. A pair of connecting plates 17 are provided on the top of the movable plate 19, each passing through a guide slot 7 and fixed to the bottom surface of the second slide rails 6. The connecting plates 17 are used to connect the second slide rails 6 and the movable plate 19. This allows the second slide rails 6 to move in a first direction, thereby enabling the two positioning assemblies to move away from and towards each other.

[0046] A movable rod 9 is slidably sleeved on the second slide rail 6. A positioning tube 10 is provided at one end of the movable rod 9 near the fastening bolt 23. The positioning tube 10 is inserted and matched with the fastening bolts 23 at both ends of the CPU heat dissipation module 22. When the two movable plates 19 approach each other, the two second slide rails 6 will carry the movable rod 9 to approach each other, thereby shortening the distance between the positioning tubes 10. This setting facilitates adjustment according to different lengths and sizes of CPU heat dissipation modules 22, improving adaptability. Furthermore, the original fastening bolts 23 at both ends of the CPU heat dissipation module 22 limit and fix the entire module, avoiding the problem of shell denting caused by clamping from both sides in the traditional method, reducing the probability of damage and improving practicality.

[0047] Furthermore, the positioning tube 10 is provided with a socket to accommodate the insertion of the fastening bolt 23, and the insertion direction is axial, which can also provide adaptability to different height dimensions of the CPU heat dissipation module 22 in the axial direction.

[0048] Preferably, by Figure 1 and Figure 3 As shown, in this embodiment, symmetrically distributed fixing plates 12 are provided on the second slide rail 6, and a support rod 13 that passes through the two moving rods 9 is connected between the two fixing plates 12. The support rod 13 has the function of limiting support, which can ensure that the moving rods 9 move smoothly. The support rod 13 and the two fixing plates 12 are located on one side of the second slide rail 6, and their main function is to adjust the movement of the two moving rods 9 in the second direction.

[0049] A support plate 14 is provided on the same side as the fixing plate 12 at the middle of the second slide rail 6 or at the middle of the support rod 13. Two return springs 15 are sleeved around the outer ring of the support rod 13. One end of each return spring 15 abuts against the support plate 14, and the other end abuts against the moving rod 9. A fixing piece 11 is provided at the top of the moving rod 9 for manually adjusting its position. That is, return springs 15 are clamped between the support plate 14 and the moving rods 9 on both sides, allowing each moving rod 9 to move closer to or further away from the support plate 14, thereby enabling the two moving rods 9 to move closer to or further away from each other, ultimately achieving adjustable clamping of CPU cooling modules 22 of different widths.

[0050] Two reset springs 15 push the moving rods 9 with their own elasticity, causing the two moving rods 9 on the same side to move away from each other. In use, the user only needs to move the fixing plate 11 to adjust the spacing of the positioning tubes 10 on the moving rods 9 according to the original spacing of the fastening bolts 23 at both ends of the CPU heat dissipation module 22, ensuring that the fastening bolts 23 are accurately inserted into the positioning tubes 10. Then, the fixing plate 11 is loosened. Due to the elasticity of the reset springs 15, the CPU heat dissipation module 22 can be initially limited. Then, the hand knob 8 is turned counterclockwise. Through the counterclockwise rotation of the forward and reverse threaded rods 20, the moving rods 9 on both sides are forced to move away from each other, realizing the pulling action to both sides, thereby achieving quick limiting. The operation is simple and convenient to use.

[0051] Preferably, by Figure 1 and Figure 2 As shown in this embodiment, symmetrically distributed first slide rails 4 are provided on both sides of the protrusion of the main body plate 1. Sliding seats 5 are slidably sleeved on the first slide rails 4. The sliding seats 5 are fixedly connected to the bottom surfaces of both ends of the second slide rail 6. The first slide rails 4 and the sliding seats 5 can ensure that the second slide rail 6 can move stably, reduce the probability of shaking, and increase the structural stability of the device.

[0052] Preferably, by Figure 1 and Figure 4 As shown in this embodiment, symmetrically distributed positioning rods 18 are provided in the inner cavity 16. The positioning rods 18 pass through the two movable plates 19 and are slidably guided to the movable plates 19. The positioning rods 18 have the function of supporting and limiting, which can ensure that the movable plates 19 move smoothly and reduce the probability of shaking.

[0053] Preferably, by Figure 1 and Figure 5 As shown, in this embodiment, perforations 21 are provided at all four corners of the main body plate 1;

[0054] A suction cup 2 is provided at the perforation 21. The screw at the top of the suction cup 2 is inserted into the perforation 21. The suction cup 2 is located below the main body plate 1. A screw sleeve 3 is screwed onto the screw of the suction cup 2.

[0055] When in use, first place the device flat on the workbench. After the four suction cups 2 are attached to the smooth surface, turn the screw sleeve 3 clockwise to pull the suction cups 2, so that the suction cups 2 are firmly attached to the workbench and the main body plate 1 is stably installed.

[0056] Components not described in detail in this article are existing technologies.

[0057] The working principle and usage process of this utility model are as follows: First, place the device flat on a workbench. After the four suction cups 2 are attached to the smooth surface, turn the screw sleeve 3 clockwise to pull the suction cups 2, thus firmly adhering them to the workbench and stably installing the main body plate 1. The user only needs to adjust the spacing of the positioning tubes 10 on the moving rods 9 according to the spacing of the original fastening bolts 23 at both ends of the CPU heat dissipation module 22, ensuring that the fastening bolts 23 are accurately inserted into the positioning tubes 10. Then, loosen the screw sleeve 11. The elastic force of the return spring 15 initially limits the CPU heat dissipation module 22. Then, turn the hand knob 8 counterclockwise. Through the counterclockwise rotation of the forward and reverse threaded rods 20, the moving rods 9 on both sides are forced to move away from each other, achieving a pulling action to both sides, thus achieving rapid limiting. The operation is simple and convenient.

[0058] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in this application is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept.
