Description

Technical Field

[0001] The utility model relates to the field of heat dissipation fin processing, in particular to a punching positioning auxiliary fixture for heat dissipation fins. Background Technique

[0002] Before the heat dissipation fins are processed into finished products, they need to be punched. By punching, the heat dissipation surface area is increased, the air flow direction is guided through the hole structure, the air convection speed is accelerated, and heat accumulation is reduced. At the same time, punching is also required to achieve the positioning function of fin installation. Therefore, punching operations need to be carried out at multiple positions on the top surface and side surface of the heat dissipation fins. For small-batch punching of heat dissipation fins, the current method is to use manual positioning for punching. For large-batch operations, only one surface of one heat dissipation fin can be punched at a time. After the punching operation on each surface is completed, the direction needs to be adjusted to perform the operation on another surface, which seriously increases the processing time. Moreover, after the heat dissipation fin is flipped, the positioning tool needs to be readjusted to ensure the accuracy of punching positioning. This method will seriously increase the punching time, reduce the processing efficiency, and it is easy to have the problem of punching position misalignment. Content of the Utility Model

[0003] In view of the above problems, the utility model provides a punching positioning auxiliary fixture for heat dissipation fins, which can eliminate the problem of repeated adjustment of positioning, can simultaneously position the punching positions of different end faces of the heat dissipation fins, does not need to be adjusted back and forth, can eliminate positioning failure, and improve the punching efficiency.

The first positioning plate, the second positioning plate and the positioning base are in a "C" shape. On the surface of the first positioning plate away from the positioning base, a plurality of first positioning sunk holes corresponding to the outer contour of the heat dissipation fin are arranged at intervals along its length direction. At one end of the second positioning plate in the thickness direction away from the positioning base, a plurality of second positioning sunk holes corresponding to the number of the first positioning sunk holes are arranged at intervals along its length direction. One end of the second positioning sunk hole close to the first positioning plate is an opening. A positioning clamping plate is arranged outside the second positioning sunk hole.

Detailed Implementation

[0019] The embodiments of this utility model will be further described below with reference to the accompanying drawings. Example

[0020] like Figures 1-3As shown in the figure, a positioning and auxiliary fixture for punching heat dissipation fins includes a first positioning plate 1, a second positioning plate 2, and a positioning base 3 that are successively connected and rectangular. The first positioning plate 1, the second positioning plate 2, and the positioning base 3 are parallel to each other in the length direction. The first positioning plate 1, the second positioning plate 2, and the positioning base 3 are in a "C" shape. On the side of the first positioning plate 1 away from the positioning base 3, a plurality of first positioning counterbores 11 corresponding to the outer contour of the heat dissipation fins are arranged at intervals along its length direction. At one end of the second positioning plate 2 in the thickness direction away from the positioning base 3, a plurality of second positioning counterbores 21 corresponding to the number of the first positioning counterbores 11 are arranged at intervals along its length direction. One end of the second positioning counterbore 21 close to the first positioning plate 1 is an opening, and a positioning clamping plate 4 is arranged outside the second positioning counterbore 21. Tensioning blocks 5 are arranged on one side of the first positioning counterbore 11 and the second positioning counterbore 21.

[0021] The working principle of the above technical solution is as follows:

[0022] The first positioning plate 1, the second positioning plate 2, and the positioning base 3 are in a "C" shape. The first positioning counterbores 11 on the first positioning plate 1 horizontally place the heat dissipation fins 8, and the second positioning counterbores 21 on the second positioning plate 2 vertically place the heat dissipation fins 8 through the opening. The vertically placed heat dissipation fins 8 are positioned by the positioning clamping plate 4 to prevent them from detaching from the second positioning counterbores 21. The placed heat dissipation fins 8 are tensioned and fixed by the tensioning blocks 5. In a vertical drilling machine, through the set drill bit, the heat dissipation fins placed on the first positioning counterbores 11 and the second positioning counterbores 21 can be punched simultaneously, and the punching operations at two mutually perpendicular positions of the heat dissipation fins can be achieved simultaneously. There is no need to adjust the tool position and fix the workpiece back and forth, which can significantly improve the operation efficiency and ensure the accuracy and reliability of punching.

[0023] A support plate 6 is arranged between the positioning base 3 and the first positioning plate 1 and the second positioning plate 2. The support plate 6 is perpendicular to the first positioning plate 1, the second positioning plate 2, and the positioning bottom plate 3. By setting the support plate 6, the overall stability of the fixture can be ensured.

[0024] [[ID=!2]]One end of the tensioning block 5 facing away from the first positioning counterbore 11 or the second positioning counterbore 21 is connected to a tensioning power mechanism 7. The tensioning power mechanism 7 is a cylinder, and rapid tensioning and blanking can be achieved by controlling the cylinder.

[0025] The positioning clamping plate 4 includes a positioning strip 41, a connecting bolt 42 for fixedly connecting the positioning strip 41 and the second positioning plate 2, and an adjusting bolt 43 for fixing the heat dissipation fins. The stability and reliability of positioning can be ensured by means of threaded connection.

[0026] The positioning base 3, the first positioning plate 1, and the second positioning plate 2 are all connected to each other by threads, which is convenient for installation and disassembly, and the fixture can be flexibly assembled according to heat dissipation fins of different models and sizes.

[0027] The positioning base 3 is equipped with mounting holes, which can be easily fixed on the drilling machine to ensure the stability of the drilling operation.
