Description

Technical Field

[0001] This utility model relates to the field of heat sink processing technology, specifically a heat sink clamping processing tool. 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] The manufacturing process of heat sinks may involve multiple steps, such as cutting, drilling, welding, and milling. Heat sinks are typically large and thin, making them prone to deformation. Therefore, a clamping process is needed to prevent them from moving or deforming. To ensure the heat sink maintains the correct position during clamping and to avoid deformation or non-compliance with specifications, specialized tooling is often used for clamping and positioning. Therefore, a heat sink clamping tooling is required.

[0004] However, most existing heat sink clamping processing fixtures are not easy to adjust in position to accommodate different heat sinks, and cannot meet a wide range of usage requirements, thus making them not very practical. Therefore, a heat sink clamping processing fixture is proposed to address the above problems. Utility Model Content

[0005] To overcome the shortcomings of existing technologies and solve the problem that most existing heat sink clamping processing fixtures are inconvenient to adjust the position of the heat sinks to adapt to different heat sinks, and cannot meet more usage needs, thus making the fixture less practical, this utility model proposes a heat sink clamping processing fixture.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a heat sink pressing tooling according to this utility model includes a base plate, and a pressing table is fixedly connected to the center of the top of the base plate.

[0007] The top edge of the base plate is fixedly connected to a plurality of evenly distributed support columns. The support columns have mounting grooves inside, one side of which extends to the outside of the support column. An adjustment component is provided inside the mounting groove, and a positioning component is provided on one side of the adjustment component.

[0008] The positioning component includes a positioning plate that is installed on one side of the adjustment component via a disassembly component. A guide component is provided between the positioning plate and the support column, and a positioning pad is fixedly connected to one side of the positioning plate.

[0009] Preferably, the adjustment assembly includes a threaded rod rotatably connected between the upper and lower surfaces inside the mounting groove via a bearing. An internal threaded sleeve is threadedly connected to the outer surface of the threaded rod. The internal threaded sleeve is slidably connected to the mounting groove. One side of the internal threaded sleeve passes through one side of the support column. A motor is fixedly installed on the top of the support column. The output end of the motor is fixedly connected to the top of the threaded rod.

[0010] Preferably, the disassembly assembly includes an electric push rod fixedly installed inside the internal threaded sleeve plate, the output end of the electric push rod extending to the outside of the internal threaded sleeve plate, a connecting plate fixedly connected to the output end of the electric push rod, an installation hole being provided inside the connecting plate, one side of the installation hole extending to the outside of the connecting plate, an installation rod being installed inside the installation hole via a plug-in assembly, and the installation rod being fixedly connected to the positioning plate.

[0011] Preferably, the plug-in assembly includes a through hole formed inside the mounting rod, an insertion hole is formed on the lower surface of the mounting hole, and a through groove is formed on the upper surface of the mounting hole. A plug rod is slidably connected inside the through groove by a spring. The bottom end of the plug rod passes through the through hole and is inserted into the insertion hole.

[0012] Preferably, the guide assembly includes sliding grooves formed on both sides of the support column, a slider is slidably connected inside the sliding groove, a fixing block is fixedly connected to one side of the slider, a sleeve is fixedly connected to one side of the fixing block, a guide rod is slidably connected inside the sleeve, and the guide rod is fixedly installed with the positioning plate by screws.

[0013] Preferably, the top end of the insertion rod extends to the outside of the connecting plate, a handle plate is fixedly connected to the top end of the insertion rod, and the positioning pad is made of rubber.

[0014] Preferably, the top of the base plate is fixedly connected with a plurality of evenly distributed handles, each of which is located between two support columns.

[0015] The advantages of this utility model are:

[0016] 1. This utility model uses a motor to operate when energized, which drives a threaded rod to rotate. The rotation of the threaded rod then causes the threaded sleeve plate connected to it to slide inside the mounting groove. The sliding of the threaded sleeve plate can move and adjust the position of the positioning component, making it convenient for the tooling to position and clamp different heat sinks. This makes the tooling highly adaptable and practical. The motor can rotate in both directions, and the rotation of the motor drives the threaded rod to rotate in both directions, allowing the positioning plate of the positioning component to move up and down to adjust its position to accommodate different heat sinks.

[0017] 2. This utility model uses a plug rod inserted through a through hole to limit the insertion of the mounting rod inside the mounting hole, ensuring the mounting rod is securely installed inside the mounting hole. When the mounting rod needs to be disassembled, moving the plug rod causes it to move, and the movement of the plug rod compresses the spring. The spring's rebound force facilitates the reset movement of the plug rod. Then, the plug rod can be removed from the through hole to disassemble the mounting rod. Furthermore, when the mounting rod is removed from the mounting hole, the positioning plate and positioning pad can be disassembled, allowing for the removal and replacement of the positioning plate and positioning pad, and facilitating the removal and replacement of the positioning plate if it is damaged.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] Please see Figure 1-4 As shown, a heat sink pressing tooling includes a base plate 1, and a pressing table 2 is fixedly connected to the top center of the base plate 1;

[0028] The top edge of the base plate 1 is fixedly connected to a plurality of evenly distributed support columns 3. The support columns 3 have an installation groove 4 inside. One side of the installation groove 4 extends to the outside of the support column 3. An adjustment component 5 is provided inside the installation groove 4. A positioning component 6 is provided on one side of the adjustment component 5.

[0029] The positioning component 6 includes a positioning plate 65 installed on one side of the adjustment component 5 via a disassembly component. A guide component is provided between the positioning plate 65 and the support column 3. A positioning pad 61 is fixedly connected to one side of the positioning plate 65. During operation, the bottom of the base plate 1 is first placed against a flat ground to stabilize the fixture. After the fixture is stabilized, the heat sink to be clamped is placed on the top of the clamping table 2. The position of the positioning component 6 can be adjusted by the adjustment component 5 inside the support column 3 to accommodate different heat sinks for clamping and positioning. The positioning plate 65 of the positioning component 6 can correspond to the position where the heat sink can be clamped. The positioning component 6 then clamps and positions the heat sink with the positioning plate 65 and the positioning pad 61. The heat sink is then clamped by an external clamping device. The clamping and positioning by the positioning component 6 prevents the heat sink from moving during the clamping process and avoids affecting the processing effect.

[0030] The adjustment component 5 includes a threaded rod 52 rotatably connected between the upper and lower surfaces inside the mounting groove 4 via a bearing. An internally threaded sleeve 53 is threadedly connected to the outer surface of the threaded rod 52. The internally threaded sleeve 53 is slidably connected to the mounting groove 4. One side of the internally threaded sleeve 53 extends through one side of the support column 3. A motor 51 is fixedly mounted on the top of the support column 3, and the output end of the motor 51 is fixedly connected to the top of the threaded rod 52. During operation, the motor 51 is energized, causing it to rotate. This rotation of the threaded rod 52 causes the internally threaded sleeve 53, which is threaded to it, to slide within the mounting groove 4. The sliding of the internally threaded sleeve 53 allows the positioning component 6 to move and adjust its position, facilitating the positioning and clamping of different heat sinks. This makes the tooling highly adaptable and practical. Furthermore, the motor 51 can rotate in both directions, which in turn causes the threaded rod 52 to rotate in both directions, allowing the positioning plate 65 of the positioning component 6 to move up and down to adjust its position to accommodate different heat sinks.

[0031] The disassembly assembly includes an electric push rod 8 fixedly installed inside the internal threaded sleeve 53. The output end of the electric push rod 8 extends to the outside of the internal threaded sleeve 53, and a connecting plate 66 is fixedly connected to the output end of the electric push rod 8. A mounting hole 68 is opened inside the connecting plate 66, and one side of the mounting hole 68 extends to the outside of the connecting plate 66. A mounting rod 69 is installed inside the mounting hole 68 through a plug-in assembly. The mounting rod 69 is fixedly connected to the positioning plate 65. During operation, the electric push rod 8 can drive the connecting plate 66 and the mounting rod 69 installed on the connecting plate 66 through the plug-in assembly to move together. It also drives the positioning plate 65 and the positioning pad 61 to move under the guidance of the guide assembly to clamp and position the heat sink that needs to be pressed, and prevents movement during the pressing process. At the same time, the plug-in assembly facilitates the disassembly and installation of the mounting rod 69 and the mounting hole 68, and also facilitates the disassembly and installation of the positioning plate 65 and the positioning pad 61.

[0032] The insertion assembly includes a through hole 613 formed inside the mounting rod 69, a insertion hole 614 formed on the lower surface of the mounting hole 69, and a through groove 610 formed on the upper surface of the mounting hole 69. A rod 611 is slidably connected to the groove 610 via a spring 612. The bottom end of the rod 611 passes through the through hole 613 and is inserted into the insertion hole 614. During operation, the rod 611, passing through the through hole 613 and inserted into the insertion hole 614, limits the insertion of the mounting rod 69 inside the mounting hole 68, thereby ensuring the mounting rod 69... The mounting rod 69 is securely installed inside the mounting hole 68. When it is necessary to disassemble the mounting rod 69, the insertion rod 611 is moved, and the insertion rod 611 will compress the spring 612 when it moves. The spring 612 is compressed and its rebound force facilitates the reset movement of the insertion rod 611. Then the insertion rod 611 is moved out of the through hole 613, and the mounting rod 69 can be disassembled. When the mounting rod 69 is moved out of the mounting hole 68, the positioning plate 65 and the positioning pad 61 can be disassembled, so that the positioning plate 65 and the positioning pad 61 can be disassembled and replaced, and it is convenient to disassemble and replace the positioning plate 65 if it is damaged.

[0033] The guiding assembly includes grooves 616 formed on both sides of the support column 3. A slider 617 is slidably connected inside the grooves 616. A fixing block 62 is fixedly connected to one side of the slider 617, and a sleeve 63 is fixedly connected to one side of the fixing block 62. A guide rod 64 is slidably connected inside the sleeve 63. The guide rod 64 is fixedly installed to the positioning plate 65 by a screw 615. During operation, the sliding of the guide rod 64 inside the sleeve 63 guides the movement of the positioning plate 65, making its movement more stable and facilitating positioning. The positioning plate 65 is stably moved and clamped for positioning. When the positioning plate 65 and the positioning pad 61 are disassembled, the guide rod 64 can be moved out from inside the sleeve 63. The guide rod 64 is fixedly installed on the positioning plate 65 by the screw 615. Therefore, the positioning plate 65 can be disassembled and replaced by rotating the guide rod 64 so that the screw 615 can be turned out from inside the guide plate, which makes it convenient to use. When the positioning plate 65 is moved up and down for adjustment, the movement of the positioning plate 65 and the guide rod 64, and the sleeve 63 and the fixing block 62 can be limited by the sliding of the slider 617 inside the slide groove 616.

[0034] The top end of the insertion rod 611 extends to the outside of the connecting plate 66, and a handle plate 67 is fixedly connected to the top end of the insertion rod 611. The positioning pad 61 is made of rubber. During operation, the handle plate 67 facilitates the movement of the insertion rod 611, and the rubber positioning pad 61 has a good anti-slip effect when clamping and positioning.
