While these dedicated fixtures improve machining accuracy to some extent, they suffer from the following problems: First, high fixture costs, as each type of heat sink requires a specific fixture, resulting in high design and manufacturing costs. Second, low production efficiency, as different fixtures need to be changed when producing different models of heat sinks, which is time-consuming and affects the overall efficiency of the production line. Third, poor adaptability, as the types of heat sinks increase, existing fixtures struggle to meet the machining needs of all types of heat sinks. Utility Model Content

[0004] To address the aforementioned shortcomings, the purpose of this utility model is to propose a processing fixture applicable to various types of heat sinks, which can clamp heat sinks of different sizes and models by pushing the top holding blocks on both sides.

[0026] The following is combined with Figures 1 to 5 This invention describes a processing fixture applicable to various types of heat sinks, according to an embodiment of the present invention.

[0027] A processing fixture applicable to various types of heat sinks includes a base plate 1, guide rails 2, moving blocks 3, top holding blocks 4, swing bars 5, pulling members 6, and a motor 7. Guide rails 2 are installed on both the front and rear sides of the base plate 1, with corresponding positions on both sides. The moving blocks 3 are slidably installed on the guide rails 2. Swing bars 5 are installed on both the left and right sides of the base plate 1. The driving end of the motor 7 is connected to the center of the swing bars 5, and the motor 7 drives the swing bars 5 to swing. Pulling members 6 are connected to both ends of the swing bars 5. One end of the pulling member 6 is rotatably connected to one end of the swing bars 5, and the other end of the pulling member 6 is rotatably connected to one end of the adjacent moving blocks 3. Top holding blocks 4 can be detachably installed on one side of each side of the moving blocks 3. The position of the top holding blocks 4 can be adjusted back and forth at the moving blocks 3. The top holding blocks 4 are used to hold the heat sink.

[0028] A processing fixture applicable to various types of heat sinks is provided for clamping heat sinks of different types and models. The heat sink is placed between two top holding blocks 4, and two moving blocks 3 move accordingly to push the top holding blocks 4 to clamp the heat sink. This fixture is applicable to heat sinks of different sizes, eliminating the need for specific fixtures for different sizes of heat sinks, thus reducing the cost of manufacturing heat sinks. One fixture can be used for different models of heat sinks, eliminating the need for frequent fixture changes, which can improve the cost of manufacturing heat sinks. This fixture is adaptable to heat sinks of different sizes.

[0029] Motor 7 drives swing bar 5 to swing. The two ends of swing bar 5 push the pull parts 6 at both ends to pull moving block 3 to move, so that top holding block 4 clamps or releases heat sink. By using swing bar 5 and pull parts 6 to pull top holding block 4, the top holding blocks 4 on both sides can move simultaneously, and the clamping force on heat sink is consistent, which is convenient for stable clamping of heat sink.

[0030] The top holding block 4 can be detachably installed on the movable block 3. The top holding block 4 with the corresponding clamping surface can be replaced according to the different shapes of heat sinks to facilitate clamping the heat sink.

[0031] Understandably, motor 7 is mounted below substrate 1. Figure 1 Only the end face of the drive end of motor 7 is displayed.

[0032] Specifically, when the two swing bars 5 swing and support the heat sink, the ends of the swing bars 5 on both sides facing the heat sink also support the heat sink, thus supporting and fixing the heat sink from all sides, making the heat sink more stable during the fixing process. When the swing bars 5 on both sides swing, one end of the swing bars 5 on both sides swings towards the heat sink, so that one end of the swing bar 5 supports the heat sink.

[0033] Specifically, the pulling component 6 includes a first screw 61, a nut 62, and a connecting sleeve 63. Both ends of the first screw 61 are fitted with nuts 62 and connecting sleeves 63. One end of the connecting sleeve 63 is threaded onto the first screw 61, and the nut 62 rests against the end face of the connecting sleeve 63. The other end of the connecting sleeve 63 has a connecting hole 64. The connecting sleeve 63 can be rotated and twisted with the first screw 61 via the thread, thereby adjusting the length of the pulling component 6. The length of the pulling component 6 can be adjusted according to the size of the heat sink, facilitating the pulling component 6 to pull the moving block 3 and push the supporting block 4 to support heat sinks of different sizes and models. After the connecting sleeve 63 and the first screw 61 are rotated, the nut 62 is rotated against the end face of the connecting sleeve 63, fixing the connecting sleeve 63 to the first screw 61. This prevents the connecting sleeve 63 from easily twisting and avoids displacement when supporting the heat sink.

[0034] Specifically, the connecting sleeve 63 with the connecting hole 64 at one end is annular. This facilitates the connecting sleeve 63 in supporting the heat sink and prevents the surface of the connecting sleeve 63 from damaging the heat sink.

[0035] To further explain, a circular sleeve 8 is installed on the top of the connecting sleeve 63. The center hole of the circular sleeve 8 is concentric with the connecting hole 64. The circular sleeve 8 is rotatably installed, and its diameter is larger than the diameter of the annular end of the connecting sleeve 63. The circular sleeve 8 is used to hold the heat sink. The heat sink can be held by the circular sleeve 8. Because the circular sleeve 8 is rotatably installed, it can rotate on the surface of the heat sink when it just touches the heat sink and when force is applied, further preventing damage to the heat sink.

[0036] Specifically, the movable block 3 has a clearance opening at one end where the top holding block 4 is mounted. The top holding block 4 is located at the clearance opening, and grooves 31 are provided on both sides of the clearance opening. Sliding blocks 41 protrude from both sides of the top holding block 4, and the sliding blocks 41 on both sides slide into the grooves 31 respectively. An adjusting rod 9 is provided at the clearance opening, with its two ends connected to the top holding block 4 and the movable block 3 respectively. The adjusting rod 9 is used to adjust the position of the top holding block 4. Depending on the size and model of the heat sink, the top holding block 4 moves within the grooves 31 via the sliding blocks 41, and the adjusting rod 9 then holds and fixes the position of the top holding block 4, allowing it to hold the heat sink. The length of the adjusting rod 9 is adjustable, allowing its position to be adjusted according to the position of the top holding block 4.

[0037] Specifically, the adjusting rod 9 includes a second screw 91, a threaded sleeve 92, and a fixed sleeve 93. One end of the second screw 91 is connected to the inner wall of the relief opening, and the other end of the second screw 91 is fitted with the threaded sleeve 92. The threaded sleeve 92 can rotate and move within the threaded portion of the second screw 91. The fixed sleeve 93 is installed on the rear side of the top support block 4, and one end of the threaded sleeve 92 passes through the inner cavity of the fixed sleeve 93 and is movably connected. The threaded sleeve 92 and the fixed sleeve 93 work together to adjust the length of the adjusting rod 9. The movable connection of one end of the threaded sleeve 92 through the inner cavity of the fixed sleeve 93 facilitates the rotation of the threaded sleeve 92 and the second screw 91, thereby adjusting the length.

[0038] To further explain, the inner cavity of the fixing sleeve 93 is convex, and the diameter of the end of the threaded sleeve 92 that penetrates into the inner cavity of the fixing sleeve 93 is larger than the outer opening of the inner cavity of the fixing sleeve 93. This fixes the threaded sleeve 92 at the fixing sleeve 93, thereby pulling the top holding block 4 and preventing the top holding block 4 from falling off.

[0039] Specifically, two guide rails 2 are installed on both the front and rear sides of the substrate 1, and the two guide rails 2 are parallel to each other. This allows the moving block 3 to move stably along the guide rails 2 without easily shaking.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.
