Description

Technical Field

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

[0002] In the process of machining heat sinks or products with cooling fins, the heat sinks are usually made of flexible materials such as aluminum alloys and are often plate-shaped. The cooling fins are prone to deformation and bending during machining, and the joints of the heat sink's shape must be aligned smoothly, which significantly increases the overall machining difficulty. In actual machining, a heat sink fixture can be used to assist. By placing the heat sink on the contour positioning plate of the heat sink fixture, with the positioning plate positioned between the adjacent cooling fins, the heat sink fixture can not only accurately position the heat sink, but also support and protect the cooling fins, effectively avoiding bending and deformation of the heat sink during machining, and ensuring smooth machining. One-piece positioning plates are difficult to repair or replace locally. Often, damage to one part requires replacing the entire positioning plate, increasing maintenance costs and wasting resources, and also prolonging maintenance time and affecting the machining progress.

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0027] Example 1 Reference Figures 1-7This is the first embodiment of the present invention. This embodiment provides a positioning fixture for heat sink processing. The positioning fixture for heat sink processing includes a fixture assembly 1 and a mounting assembly 2. The two work together so that when one of the positioning plates is damaged, it can be disassembled and replaced separately, avoiding the waste of resources caused by replacing the entire positioning fixture due to damage to one part.

[0028] The clamp assembly 1 includes a clamp piece 11, and a frame 12 is provided on the outer side of the clamp piece 11.

[0029] The clamping piece 11 can accurately position the heat sink and also support and protect the heat dissipation teeth of the heat sink, effectively avoiding problems such as milling bending and deformation of the heat sink during processing. The frame 12 is used to support the clamping piece 11 and prevent the clamping piece 11 from shifting.

[0030] The mounting component 2 is set inside the frame 12 and includes a mounting piece 21. The mounting piece 21 includes a clamping piece 211, which is fixed to the inner wall of the frame 12. A clamping plate 212 is provided on the top of the clamping piece 11. A positioning strip 213 is provided on one side of the frame 12, and a positioning pin 214 is provided on one side of the positioning strip 213.

[0031] The clamping piece 211 is an elastic element. When the clamping piece 11 is installed in the frame 12, the clamping piece 11 can be initially fixed by the rebound of the clamping piece 211. Then, the clamping plate 212 is engaged with the top of the clamping piece 11 to fix the clamping piece 11. At this time, the heat sink can be installed in the frame 12 and engaged with the clamping piece 11. At the same time, the positioning pin 214 can be engaged with the positioning strip 213, so that the clamping piece 11 can be firmly fixed in the frame 12.

[0032] Example 2 Reference Figures 2-7 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0033] Specifically, a slot 211-1 corresponding to the clamping piece 211 is provided on one side of the clamping piece 11, and the clamping piece 211 is located in the slot 211-1. A positioning groove 212-1 corresponding to the clamping plate 212 is provided at one end of the clamping piece 11, and the clamping plate 212 is disposed in the positioning groove 212-1.

[0034] The clamp piece 11 can be initially fixed by the springback of the clamping piece 211 and the engagement of the slot 211-1. At this time, the clamp piece 11 can be removed by using external force to pull it out. After the clamping piece 211 and the slot 211-1 are engaged, the clamping plate 212 and the positioning groove 212-1 can be engaged to fix the clamp piece 11.

[0035] Specifically, the installation component 2 also includes a movable part 22, which includes a pressure plate 221. The pressure plate 221 is fixed to the top of the clamping plate 212, and a support plate 222 is fixed to one side of the pressure plate 221.

[0036] By moving the pressure plate 221, the clamping plate 212 can be engaged with the positioning groove 212-1, and the support plate 222 can be moved within the frame 12 to support the pressure plate 221.

[0037] Specifically, a first spring 223 is fixed to the bottom of the support plate 222, and one end of the first spring 223 is fixed to the inner wall of the frame 12.

[0038] When the support plate 222 slides within the frame 12, it can apply a squeezing force to the first spring 223. The rebound force of the first spring 223 can drive the clamping plate 212 to separate from the positioning groove 212-1, thereby releasing the clamping piece 11 from its limit and removing it.

[0039] Specifically, a cam 224 is provided on the top of the pressure plate 221, and a rotating column 225 is inserted into one side of the cam 224. The rotating column 225 is rotatably connected to one side of the frame 12 through a rotating shaft.

[0040] The user can rotate the rotating column 225 to drive the cam 224 to rotate, and the cam 224 can squeeze the pressure plate 221 to drive the pressure plate 221 to move.

[0041] Example 3 Reference Figures 1-7 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0042] Specifically, the mounting component 2 also includes a positioning element 23, which includes a knob 231, and the knob 231 is fixed to one end of the rotating column 225.

[0043] The knob 231 is designed to make it convenient for users to rotate the rotating column 225.

[0044] Specifically, a limiting groove 214-1 corresponding to the positioning pin 214 is provided on one side of the positioning strip 213, and the positioning pin 214 is located on one side of the limiting groove 214-1.

[0045] When the knob 231 is rotated, the positioning strip 213 can be rotated. After the positioning strip 213 is rotated to the designated position, the clamp piece 11 can be fixed. At this time, the heat sink and the frame 12 are engaged, which can drive the positioning pin 214 to engage with the limiting groove 214-1. This can prevent the knob 231 from rotating on its own and causing the clamp to loosen. The positioning pin 214 can limit the clamp by passing through the positioning strip 213.

[0046] Specifically, a guide bar 232 is fixed to one side of the positioning bar 213, and a guide frame 233 is slidably connected to one side of the guide bar 232. The guide frame 233 is fixed to one side of the frame 12.

[0047] When the knob 231 is rotated, the positioning strip 213 can be rotated. At this time, the positioning strip 213 can drive the guide strip 232 to slide within the guide frame 233, thereby supporting the rotation of the knob 231.

[0048] Specifically, a moving rod 234 is fixed to one side of the positioning pin 214, and a pressing plate 235 is fixed to one end of the moving rod 234.

[0049] When the heat sink is engaged with the frame 12, the heat sink can press the extrusion plate 235, which in turn drives the moving rod 234 to move. The movement of the moving rod 234 can drive the positioning pin 214 to engage with the limiting groove 214-1, and the moving rod 234 is slidably connected to the frame 12.

[0050] Specifically, a second spring 236 is fixed to one side of the moving rod 234, and one end of the second spring 236 is fixed to the inner wall of the frame 12.

[0051] When the heat sink is engaged with the frame 12 and the pressing plate 235 is pressed, a pressing force can be applied to the second spring 236. When the heat sink is separated from the frame 12, the rebound force of the second spring 236 can drive the moving rod 234 back to its original position, thereby separating the positioning pin 214 from the limiting groove 214-1 and releasing the limitation on the knob 231.

[0052] In use, the clamp piece 11 is first installed inside the frame 12. At this time, the springback of the clamp piece 211 can engage with the slot 211-1 to complete the initial fixation. After the clamp piece 11 is fully installed inside the frame 12, the knob 231 is turned. The knob 231 can drive the positioning strip 213 to rotate. The positioning strip 213 drives the guide strip 232 to slide inside the guide frame 233. At the same time, the rotation of the knob 231 can drive the rotating column 225 to rotate. The rotation of the rotating column 225 can drive the cam 224 to rotate. When the cam 224 rotates, it can press the pressure plate 221. When the pressure plate 221 moves, it drives the support plate 222 to move. The movement of the support plate 222 can apply a compressive force to the first spring 223. The movement of the pressure plate 221 causes the slot 212 and the positioning slot 212-1 to engage, thus fixing the clamp piece 11 inside the frame 12.

[0053] Then the heat sink can be engaged with the frame 12. At this time, the heat sink can press the extrusion plate 235. The extrusion plate 235 drives the moving rod 234 to move. When the moving rod 234 moves, it can apply a compressive force to the second spring 236. At the same time, the moving rod 234 can drive the positioning pin 214 to engage with the limiting groove 214-1, thereby limiting the knob 231 and firmly fixing the clamp piece 11 in the frame 12.

[0054] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
