Description

Technical Field

[0001] The utility model specifically relates to the technical field of pneumatic pressing, and specifically relates to a pneumatic pressing fixture for a heat sink. Background Technique

[0002] When the heat sink is pressed and installed, it is necessary to ensure the consistency of the installation position and the pressing force. However, the current traditional installation method is manual installation. In this process, the pressing force on the heat sink is uneven, which will cause the heat sink to become loose during use.

[0003] When the current traditional pneumatic pressing device presses the heat sink, it can only realize the cooperative pressing between the upper die and the lower die driven by the cylinder. However, during pressing, it is impossible to effectively ensure that the pressure of the cylinder is the same each time, which will cause the pressure received by each heat sink during pressing to be different, and thus the heat sink will become loose during later use. During the operation of the pneumatic pressing device, when a fault occurs in the air circuit or the circuit, the repair of the traditional pneumatic device is more troublesome. It is necessary to disassemble the equipment, and the disassembly and assembly time during repair is long, which affects the working efficiency of the equipment.

[0004] After retrieval, the Chinese patent application number CN202222308135.7 discloses a pneumatic press; including an equipment bracket, a switch device, a maintenance board, a fixed foot bracket, and a press. The switch device is movably installed at the bottom of the equipment bracket, the maintenance board is fixedly installed on the equipment bracket, the fixed foot bracket is fixedly installed at the bottom of the equipment bracket, and the press is fixedly installed on the equipment bracket.

[0005] Although the structure in the above patent can achieve the pressing effect on the product, during pressing, it is impossible to effectively ensure that the pressure of the press is the same each time. In this way, during the operation process, it cannot be ensured that the pressing force received by each product is the same.

[0006] In view of the above situation, we provide a pneumatic pressing fixture for a heat sink. In this device, the pneumatic control valve is controlled by the on-off of switch one and switch two for relay one and relay two. Among them, the pressing time can be effectively adjusted through relay two, and the pressure holding effect is ensured during the pressing process. In this device, relay one, relay two, the pneumatic control valve, and the power supply module are fixedly installed inside the sealed housing. In this way, when a fault occurs during the operation of the equipment, by opening the maintenance board at the open end of the sealed housing, the circuit system and the air circuit system can be effectively overhauled and maintained, reducing the disassembly time of the equipment and greatly improving the working efficiency of the equipment.
