Description

Technical Field

[0001] The utility model relates to the technical field of heat sink punching, in particular to a computer heat sink punching fixture. Background Art

[0002] A heat sink is a device that dissipates heat from heat-generating electronic components in electrical appliances. It is usually made of aluminum alloy, brass or bronze in the form of plates, sheets or multiple sheets. The CPU central processing unit in a computer requires a fairly large heat sink for heat dissipation and cooling to ensure the normal operation of the CPU. In addition to milling grooves, the heat sink also needs to be punched during processing. In order to ensure stability during punching, a heat sink punching fixture is required to clamp and fix it.

[0003] The publication number CN 218835758 U discloses a computer heat sink punching fixture, including a base and a handle, a shell is arranged on the left and right sides of the upper end surface of the base, the lower end surface of the left shell is fixedly connected to the upper end surface of the base, the outer end surface of the shell is fixedly connected to a sleeve, the front and rear end surfaces of the shell are fixedly connected to sliding wheels, the inner side of the sleeve is slidably connected to a sliding rod, one end of the sliding rod is fixedly connected to a connecting plate, the other end of the sliding rod is fixedly connected to a pull ring, and the outer end surface of the connecting plate is fixedly connected to a friction block. The heat sink punching fixture is capable of quickly and stably clamping the heat sink sample through the provision of the sliding wheel, sliding rod, friction block, etc., thereby solving the problem that the existing punching fixture for fixing the heat sink sample has a relatively simple structural design, resulting in insufficient positioning constraint of the fixture on the entire heat sink, which makes it easy to deviate during the punching process, thereby improving the practicality of the device.

[0004] However, the punching fixture has the following shortcomings: the device can clamp and position the heat sink when in use, but it can only clamp and fix the sides of the heat sink when in use, and lacks the positioning effect of pressing the top of the heat sink, which causes the heat sink to easily jump slightly under the force of the punching, affecting the punching operation and resulting in poor positioning effect.

[0005] Therefore, the utility model provides a computer heat sink punching fixture to solve the above problems. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides a computer heat sink punching fixture to solve the above problems.

[0007] To achieve the above purpose, the utility model is implemented through the following technical solutions: a computer heat sink punching fixture, including a mounting box, a punching bracket is connected through the top of the mounting box, a plurality of bidirectional threaded rods are rotatably connected in the mounting box, two symmetrically distributed side clamps are provided on the threaded sleeves of the bidirectional threaded rods, the tops of the side clamps are slidably extended to the outside of the mounting box, and a pressing assembly is provided through the tops of the side clamps;

The two central bidirectional threaded rods can be conveniently rotated synchronously by using the arranged driven bevel gears, support plates, transmission shafts and active bevel gears in combination.

[0011] Preferably, a linkage gear is fixedly sleeved on the transmission shaft, a second motor is fixedly connected in the installation box, a driving gear is fixedly connected to the output shaft of the second motor, and the driving gear is meshed with the linkage gear. The transmission shaft can be conveniently controlled to rotate by using the linkage gear, the second motor and the driving gear in combination.

[0012] Preferably, a plurality of load-bearing slide bars are fixedly connected in the installation box, and the load-bearing slide bars slide through the corresponding side clamps. The load-bearing slide bars and the side clamps are used in combination to conveniently support the side clamps and bear the weight, thereby facilitating smooth movement thereof.

[0013] Preferably, one side of the side clamp is fixedly connected to a side plate, and a plurality of limit rods are fixedly connected in the installation box. The limit rods slide through the corresponding side plates. The side clamp can be limited by using the side plates and limit rods in combination to prevent it from moving too far and colliding with the synchronous wheel.

[0014] Preferably, a movable opening is provided on the outer wall of the fixed cylinder, and a stop rod is fixedly connected to the outer wall of the telescopic sleeve, and one end of the stop rod slides through the movable opening. The movable opening and the stop rod are used in combination to conveniently limit the position of the telescopic sleeve, allowing it to move smoothly while limiting its moving distance.

[0015] Preferably, a side pad is fixedly connected to one side of the side clamping plate, an upper pad is fixedly connected to the bottom of the upper pressure plate, and two lower pads are fixedly connected to the top of the installation box. By using the side pads, upper pads and lower pads in combination, the computer heat sink can be conveniently clamped and fixed to increase contact friction.
