Description

Technical Field

[0001] This utility model relates to the field of metal heat sink technology, and in particular to a modular metal heat sink assembly and positioning fixture. Background Technology

[0002] Metal heat sinks are key heat dissipation components in electronic devices. Their structure typically consists of multiple thin-walled heat dissipation fins. During the manufacturing process, especially for modular heat sinks, it is necessary to collect, align, and fix the scattered heat sinks or fins. This process usually requires specialized assembly and positioning fixtures. Most existing assembly and positioning fixtures use clamping components, such as clamping blocks or moving plates, that move from both sides towards the center to gather and clamp the stacked heat sinks, facilitating subsequent welding or fastening processes.

[0003] However, the clamping components of such tooling are typically designed as rigid structures. Since metal heat sinks, especially the edges of the fins, are usually thin and easily deformed, a large impact force is generated at the moment of contact when the rigid clamping components strike the heat sink at high speed or high pressure for positioning. This rigid contact easily leads to indentations, bending deformation, or surface scratches on the heat sink edges, severely affecting product yield and appearance quality.

[0004] Therefore, this utility model proposes a modular metal heat sink assembly and positioning fixture to address the shortcomings of existing technologies. Utility Model Content

[0005] In view of the problem that the clamping components of the existing modular metal heat sink assembly and positioning fixtures are usually rigid structures, which are prone to impact force during assembly and positioning, resulting in damage or deformation of the thin heat sink edges, this utility model aims to provide a modular metal heat sink assembly and positioning fixture with an improved structure that can effectively solve the above problems.

[0006] This utility model provides a modular metal heat sink assembly and positioning fixture, including: a workbench; and at least two movable plates, which are slidably connected to the workbench and can move towards each other.

[0007] The tooling also includes a buffer mechanism that is fixedly connected to each of the moving plates.

[0008] The buffer mechanism includes a connecting plate fixedly connected to the moving plate; a shaft slidably passing through the connecting plate; a spring sleeved on the outer periphery of the shaft and used to provide buffering force; and a clamping plate fixedly connected to the front end of the shaft. When the moving plate clamps the heat sink, the clamping plate is forced to push the shaft to compress the spring, thereby achieving elastic buffering.

[0009] Preferably, the buffer mechanism further includes a flexible pad, which is fixedly connected to the surface of the clamp away from the shaft. The flexible pad is used to provide initial soft contact when in contact with the heat sink, further dispersing the impact force and avoiding scratching the surface of the heat sink.

[0010] Preferably, the buffer mechanism further includes a limiting plate, which is fixedly connected to the end of the shaft that passes through the connecting plate. The limiting plate is used to limit the reset range of the shaft and prevent the shaft from coming off the connecting plate under the action of the spring force.

[0011] Preferably, a flange is fixedly provided on the shaft, and the two ends of the spring abut against the connecting plate and the flange respectively. This arrangement provides the spring with stable and reliable axial support and preload space.

[0012] Preferably, the tooling further includes a long slot, which is formed on the worktable, and the movable plate is slidably connected to the long slot, which provides a precise guide path for the linear reciprocating motion of the movable plate.

[0013] Preferably, the tooling further includes a double-ended screw, which is rotatably connected to the long slot. The moving plate is threadedly engaged with the double-ended screw. Through the design of opposite threads at both ends on the same rod of the double-ended screw, it can synchronously drive the moving plates on both sides to move towards or away from each other when rotating.

[0014] Preferably, the tooling further includes a second helical gear, which is fixedly connected to one end of the double-ended screw and is used to receive power and drive the double-ended screw to rotate.

[0015] Preferably, the tooling further includes a helical gear one, which meshes with the helical gear two. The meshing transmission of the helical gears is used to change the direction of power transmission, for example, changing horizontal rotation into vertical rotation.

[0016] Preferably, the tooling further includes a rotating shaft, one end of which is fixedly connected to the first helical gear, for transmitting power from the motor to the first helical gear.

[0017] Preferably, the tooling further includes a motor housing and a first motor; the motor housing is fixed to the worktable; the first motor is disposed inside the motor housing, and the output end of the first motor is connected to the other end of the rotating shaft for transmission, and the first motor provides an automated power source for the entire clamping action.

[0018] This utility model has the following beneficial effects:

[0019] 1. This utility model solves the problem in the prior art where the heat sink is damaged or deformed due to impact caused by rigid contact when the clamping components gather and position the heat sink. The buffering mechanism includes a shaft that slides through the connecting plate, a spring sleeved on the shaft, and a clamping plate fixedly connected to the front end of the shaft.

[0020] 2. This utility model, by fixing a flexible pad to the surface of the clamp plate away from the shaft, further utilizes the flexible pad to make soft contact with the heat sink on the basis of the spring providing buffer, thereby further dispersing the contact pressure, avoiding scratches on the surface of the heat sink, and improving the reliability of the protection of the heat sink.

[0021] 3. This utility model uses a motor to drive a rotating shaft, which in turn drives a double-headed screw to rotate through the meshing of helical gears one and two. This, in turn, drives the threaded moving plate to move synchronously in opposite directions, solving the problems of low clamping and positioning efficiency or asynchronous movement on both sides in the prior art. It achieves the technical effects of stable transmission structure, high degree of automation, and precise and controllable clamping and positioning. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0029] Example:

[0030] Please refer to Figures 1 to 4 This utility model provides a modular metal heat sink assembly and positioning fixture, which aims to solve the problem in the prior art where the heat sink is damaged or deformed due to the impact caused by the rigid contact of the clamping components when they are gathered and positioned.

[0031] like Figure 1 and Figure 2 As shown, the modular metal heat sink assembly and positioning fixture includes a worktable 1 and at least two movable plates 10. The movable plates 10 are slidably connected to the worktable 1 and can move towards each other. The worktable 1 serves as the mounting base for the entire device to support the heat sink. The movable plates 10 are used to gather and clamp the heat sink. The fixture also includes a buffer mechanism 2 fixedly connected to each movable plate 10. The buffer mechanism 2 is used to provide elastic buffering when the movable plates 10 clamp the heat sink to avoid rigid impact.

[0032] Reference Figure 2 , Figure 3 and Figure 4 The structure of the buffer mechanism 2 is described in detail below: The buffer mechanism 2 includes a connecting plate 201, which is fixedly connected to the moving plate 10. The shaft 202 slides through the connecting plate 201. A spring 204 is sleeved on the outer periphery of the shaft 202. The two ends of the spring 204 abut against the flanges fixedly installed on the connecting plate 201 and the shaft 202, respectively. A clamping plate 205 is fixedly connected to the front end of the shaft 202. The buffer mechanism 2 also includes a flexible pad 206, which is fixedly connected to the surface of the clamping plate 205 away from the shaft 202. The flexible pad 206 is used to directly contact the heat sink. The buffer mechanism 2 also includes a limiting plate 203, which is fixedly connected to the end of the shaft 202 that passes through the connecting plate 201. The limiting plate 203 is used to limit the reset range of the shaft 202 and prevent the shaft 202 from detaching from the connecting plate 201.

[0033] The technical solution of this embodiment is that the modular metal heat sink assembly and positioning fixture also includes a long slot 3, and the long slot 3 forms a specific structural fit and connection relationship with the aforementioned workbench 1 and moving plate 10.

[0034] Please refer to Figure 1 and Figure 3Meanwhile, the movable plate 10 is slidably connected to the long groove 3. This sliding fit structure ensures the high stability and guidance of the movable plate 10 during movement.

[0035] Based on the above embodiments, the present invention may further include the following preferred technical solutions:

[0036] As a preferred embodiment, in order to achieve synchronous, opposite-direction movement of the moving plates 10, please refer to... Figure 3 The tooling also includes a double-ended screw 9, which is rotatably connected to the long groove 3, and the movable plate 10 is threadedly engaged with the double-ended screw 9.

[0037] As a preferred embodiment, in order to drive the double-ended screw 9 to rotate, please refer to... Figure 3 The tooling also includes a second helical gear 8, which is fixedly connected to one end of the double-ended screw 9.

[0038] As a preferred embodiment, in order to transmit power to helical gear 8, please refer to... Figure 3 The tooling also includes a helical gear 7, which meshes with a helical gear 8.

[0039] As a preferred embodiment, in order to drive the helical gear 7 to rotate, please refer to... Figure 3 The tooling also includes a rotating shaft 6, one end of which is fixedly connected to a helical gear 7.

[0040] As a preferred embodiment, in order to provide a power source, please refer to... Figure 1 The tooling also includes a motor housing 4 and a motor 5. The motor housing 4 is fixed to the workbench 1, and the motor 5 is installed inside the motor housing 4. The output end of the motor 5 is connected to the other end of the rotating shaft 6 for transmission.

[0041] Working principle: When it is necessary to gather and position the heat sink, the motor 5 set in the motor box 4 is started. The output end of the motor 5 is connected to the rotating shaft 6, which drives the rotating shaft 6 to rotate. One end of the rotating shaft 6 is fixedly connected to the helical gear 7. The helical gear 7 rotates and meshes with the helical gear 8. The helical gear 8 drives the double-ended screw 9 fixedly connected to one end of it to rotate. The double-ended screw 9 is rotatably connected in the long slot 3. At least two moving plates 10 threaded to the double-ended screw 9 move in opposite directions.

[0042] When the moving plate 10 moves towards the center to clamp the heat sink, the heat sink first contacts the flexible pad 206 fixed to the surface of the clamping plate 205. The flexible pad 206 achieves soft contact and transmits pressure to the clamping plate 205. The clamping plate 205 drives the fixedly connected shaft 202 to slide through the connecting plate 201. During the sliding process, the shaft 202 compresses the spring 204 sleeved on its outer periphery. The elastic deformation of the spring 204 absorbs the impact force during clamping, thereby providing buffering and avoiding rigid collision. The limiting plate 203 is fixedly connected to the end of the shaft 202 to limit the reset range of the shaft 202.

[0043] Through the buffer mechanism 2 provided on the movable plate 10, especially the synergistic buffering effect of the flexible pad 206 and the spring 204, this utility model solves the problem of heat sink damage and deformation caused by rigid clamping in the prior art.
