Clamping device for slitting of computer display card cooling fins

Abstract

The invention discloses a clamping device for slitting of computer display card cooling fins. The clamping device comprises a base, a mounting seat, movable arms, locking assemblies, top bracing assemblies and a machining table. The mounting seat is fixed to the base, the mounting seat is of a hollow cavity, an opening is formed in the top of the mounting seat, and the mounting seat is used for enabling the machining table to move up and down along the position of the opening of the mounting seat. A containing groove is formed in the middle of the machining table, vertically-put pit molding needles are evenly distributed at the bottom of the containing groove, and the upper faces of the pit molding needles are in round ball shapes and are used for containing the to-be-slit cooling fins. The movable arms capable of moving horizontally are symmetrically arranged on the two sides of the mounting seat, one locking assembly is arranged on each movable arm, when the to-be-slit cooling fins are clamped and locked, the locking assemblies can lock the to-be-slit cooling fins in the pit molding needles while ejecting the machining table upwards through the top bracing assemblies, and therefore pits in the to-be-slit cooling fins are molded.

Description

technical field [0001] The invention relates to the technical field of clamping devices, in particular to a clamping device for cutting heat sinks of computer graphics cards. Background technique [0002] As a heat conduction medium for the GPU, the heat sink of the graphics card can increase the heat exchange area of ​​the chip to achieve the purpose of rapid heat dissipation. Usually, this type of heat sink uses a copper base and aluminum fins to match, and the copper base It is in contact with the chip, and multiple sets of fins are welded on the copper base to maximize the heat dissipation area. Before welding, the heat sink needs to be cut into the required size, so a clamping device is needed for assistance processing. [0003] After investigation and analysis, the existing clamping device and the heat dissipation of aluminum fins have the following problems: [0004] 1. Due to the relatively simple structure of the existing clamping device, it is easy to vibrate whe...

AI Technical Summary

Problems solved by technology

[0004] 1. Due to the relatively simple structure of the existing clamping device, it is easy to vibrate when cutting the heat sink, which affects the quality of the slit heat sink. In addition, the simple clamping cannot guarantee the stability of the clamping ;

[0005] 2. The existing clamping device is not equipped with an ejector device, which is inconvenient for unloading and affects work efficiency after the slitting is completed;

[0006] 3. As mentioned above, most of the existing heat sinks use copper bases and aluminum fins to cooperate, and the heat dissipation effect needs to be improved; therefore, how to improve the heat dissipation effect and improve the processing efficiency in a limited space has become the focus of attention
