Description

Technical Field

[0001] This utility model relates to the field of heat sink processing technology, and more specifically, it relates to an adjustment device for heat sink processing. Background Technology

[0002] A heatsink is a device used to dissipate heat from heat-generating electronic components in electrical appliances. It is typically made of aluminum alloy, brass, or bronze and can be in the form of plates, sheets, or multiple sheets. For example, the CPU (Central Processing Unit) in a computer requires a fairly large heatsink, and power transistors, horizontal output transistors, and power amplifier transistors in a television all use heatsinks. Generally, a layer of thermal grease is applied to the contact surface between the electronic component and the heatsink during use. This allows the heat generated by the component to be more effectively conducted to the heatsink, and then dissipated into the surrounding air.

[0003] In the current technology, a processing mold is used to fix the heat sink during the heat sink processing process. The distance between the pins of heat sinks of different sizes is not consistent, and the distance between the pins of the heat sink fins cannot be adjusted, requiring the mold to be replaced. If the processing mold is used again, the heat sink will not fit the inner wall of the processing mold, thus affecting the quality of subsequent heat sink processing. However, replacing the processing mold is more troublesome and time-consuming, which will affect the efficiency of heat sink adjustment and production. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide an adjustment device for heat sink processing, which can adjust and fix the position of the heat sink body, thus achieving the clamping and fixing effect without replacing the entire mold.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an adjustment device for processing heat sinks, including a worktable, a bracket set on the worktable, and a base plate set on the bracket. A positioning frame is provided on the base plate, and two positioning blocks are provided in the positioning frame. The heat sink is placed on the two positioning blocks, and a fixing adjustment mechanism for fixing the heat sink in the positioning frame is provided on the base plate.

[0006] The present invention is further configured such that: the fixing and adjusting mechanism includes a cylinder mounted on the base plate, an ejector block mounted inside the positioning frame, sliders mounted at both ends of the ejector block, limiting rods mounted at both ends of the ejector block, and several springs mounted on the positioning frame; the positioning block is engaged with the slider and in close contact with the outer wall of the slider; the positioning frame has a connecting hole for the cylinder to extend out; the positioning frame has a side hole for placing the springs; and the springs are abutted in the side hole by screws.

[0007] The present invention is further configured such that: the end of the ejector block near the slider is provided with an inclined surface.

[0008] The present invention is further configured such that: a limiting groove for inserting a limiting rod is provided inside the ejector block.

[0009] The present invention is further configured such that the slider is fixedly connected to the positioning frame by a pin.

[0010] The present invention is further configured such that: a plurality of fixing blocks are provided on the side wall of the positioning frame, which are in contact with the outer wall of the positioning block.

[0011] In summary, this utility model has the following beneficial effects: under the action of the fixing and adjusting mechanism, when it is necessary to process heat sinks with different needle distances, the heat sink body needs to be fixed. At the same time, the position of the heat sink body can be adjusted and fixed, so that the clamping and fixing effect can be achieved without replacing the entire mold, which improves the efficiency of the operator's operation and also improves the efficiency of fixing the heat sink body.

[0021] The present invention will now be described in detail with reference to the accompanying drawings.

[0022] An adjustment device for heat sink processing, as shown in the reference. Figures 1-5 It includes a workbench 1, a support 2 set on the workbench 1 and a base plate 3 set on the support 2. A positioning frame 4 is set on the base plate 3. Several fixing blocks 9 that fit against the outer wall of the positioning block 12 are set on the side wall of the positioning frame 4. The positioning frame 4 is fixed to the base plate 3 by several screws. Two positioning blocks 12 are set inside the positioning frame 4. The heat sink is placed on the two positioning blocks 12.

[0023] The base plate 3 is provided with a fixing and adjustment mechanism for fixing the heat sink in the positioning frame 4. The fixing and adjustment mechanism includes a cylinder 5 on the base plate 3, an ejector block 6 in the positioning frame 4, sliders 8 at both ends of the ejector block 6, limit rods 7 at both ends of the ejector block 6, and several springs on the positioning frame 4. The cylinder 5 is fixed to the lower surface of the base plate 3 by several screws. The positioning block 12 is engaged with the slider 8 and in close contact with the outer wall of the slider 8. The positioning frame 4 has a connecting hole 10 for the cylinder 5 to extend out and a side hole 11 for placing the spring. The spring is abutted in the side hole 11 by screws.

[0024] The ejector block 6 has an inclined surface at one end near the slider 8, and the ejector block 6 has a limiting groove inside for the insertion of the limiting rod 7.

[0025] The slider 8 is fixedly connected to the positioning frame 4 by a pin.

[0026] Working principle: The operator places the heat sink to be processed on the positioning frame 4, and the two positioning blocks 12 on the positioning frame 4 will fit together with the heat sink. In order to adapt to different heat sinks, the heat sink needs to be fixed by a fixing and adjustment mechanism. The operator first drives the cylinder 5 to move the extended end of the cylinder 5 close to the ejector block 6, so that the ejector block 6 is lifted upward in the positioning frame 4. The two ends of the ejector block 6 with inclined surfaces will contact the slider 8 and push the slider 8. The slider 8 and the positioning block 12 are engaged together, so that the positioning block 12 will slide along the surface of the slider 8 towards both ends under force. The positioning block 12 is pushed open and makes the positioning block 12 fit with the surface of the heat sink. The spring in the side hole 11 on the side wall of the positioning frame 4 will be released by the external force of the positioning block 12, so that the positioning frame 4 is not in a state of clamping and fixing the heat sink.

[0027] When cylinder 5 is in the extended state, the operator uses an external negative pressure pump to activate it, creating negative pressure inside the positioning frame 4. Simultaneously, cylinder 5 gradually shortens, causing it to stop pushing the ejector block 6. The positioning block 12 on the slider 8, under the negative pressure inside the positioning frame 4, causes the heat sink to gradually flatten and fix itself onto the positioning block 12. Furthermore, several fixing blocks 9 around the positioning block 12 will adhere to the bottom wall of the positioning frame 4 and the outer wall of the positioning block 12 under the negative pressure, thus restricting the positioning block 12 and ensuring greater stability when it fixes the heat sink. This achieves the fixation of the heat sink, allowing it to be fixed onto the positioning block 12 and the positioning frame 4. When cylinder 5 is deactivated, it stops pushing the ejector block 6 and the positioning block 12. The spring inside the side hole 11 gradually slides back to its initial state, fixing the positioning frame 4. Different heat sink molds can be fixed depending on the type of pin, eliminating the need to replace the entire device and preventing errors during heat sink processing.

[0028] Meanwhile, when the ejector block 6 is ejected, the limiting rods 7 at both ends will restrict the ejector block 6 and make the limiting rods 7 move along the inner wall of the limiting groove to ensure the ejection and movement of the ejector block 6 in the vertical direction. In addition, the positioning blocks 12 at both ends can further restrict the movement trajectory of the ejector block 6 to prevent the ejector block 6 from deviating and affecting the accuracy and effect of the ejector block 6 in lifting and pushing the heat sink. Not only is the structure simple and convenient for the operator, but it can also change and adjust different heat sink molds according to the different heat sink pins, which can speed up the processing efficiency of heat sinks and improve the fixing effect of heat sinks to reduce errors.

[0029] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
