Description

Technical Field

[0001] This utility model relates to the field of fin threading auxiliary tools, specifically a fin threading auxiliary tool for radiator fins. Background Technology

[0002] In the production process of finned heat sinks, it is necessary to assemble the formed fins and copper tubes, and to insert multiple copper tubes through a large number of fins.

[0003] A search revealed a utility model patent with patent authorization announcement number CN220389313U, which discloses an auxiliary tool for threading radiator fins, relating to the field of machining technology. This utility model includes a worktable and limiting plates. Limiting frames are slidably engaged on both sides of the worktable, and multiple first elastic positioning blocks are parallelly engaged and fixed on the top of the worktable. Multiple limiting plates are parallelly inserted into the top of the worktable, and lifting cylinders are provided on the bottom sides of the multiple limiting plates.

[0004] Because of the large number of fins and their thinness, the copper tube is prone to wobbling during the threading process. As a result, misalignment can easily occur between the holes of the fins during the threading process, making it difficult for the copper tube to pass through quickly. Furthermore, if the axis of the copper tube is not aligned with that of the fin, the fins can be easily damaged. Utility Model Content

[0005] The purpose of this invention is to provide an auxiliary tool for threading radiator fins, which solves the problems of existing radiator copper tubes being difficult to thread and the fins being easily damaged.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary tool for threading radiator fins, comprising a base, a motor fixedly mounted on the bottom of the base, a turntable fixedly connected to the end of the output shaft of the motor, a plurality of clamping rods slidably connected inside the base and penetrating the base, a sliding rod fixedly connected to the bottom of the clamping rods and penetrating the turntable and slidably connected to the turntable, a pipe guiding mechanism provided above the base, the pipe guiding mechanism comprising a hollow sleeve, an adjusting sleeve threadedly connected to the outer side of the hollow sleeve, a sliding pin slidably connected to the side wall of the hollow sleeve and penetrating the hollow sleeve, one end of the sliding pin abutting against the adjusting sleeve, and a guide block fixedly connected to the other end of the sliding pin.

[0007] Preferably, a guide rod is fixedly connected inside the base, the guide rod passing through the clamping rod and slidably connected to the clamping rod. The guide rod provides guidance for adjusting the force applied to the clamping rod.

[0008] Preferably, the turntable has an arcuate groove inside, which extends through the turntable, and the slide rod is located within the arcuate groove. The arcuate groove allows the slide rod to be subjected to a radial force from the turntable during rotation.

[0009] Preferably, a fixing frame is fixedly connected to the outer side of the hollow sleeve, and the end of the fixing frame is fixedly connected to the base. The fixing frame provides support for the pipeline guiding mechanism.

[0010] Preferably, the guide block is provided with ball bearings, and multiple ball bearings are provided. By providing ball bearings, the friction between the radiator tube and the guide block can be reduced.

[0011] Preferably, a guide pin is fixedly connected to the inner wall of the hollow sleeve, the guide pin is slidably connected to the guide block, and a spring is provided inside the guide block. One end of the spring is fixedly connected to the guide pin, and the other end of the spring is fixedly connected to the inner surface of the guide block. The guide pin and spring provide guidance and auxiliary resetting for the lateral adjustment of the guide block.

[0012] Preferably, a travel limiting block is fixedly connected to the pin body of the sliding pin, and the travel limiting block and the sliding pin are an integral structure. The travel limiting block limits the travel of the sliding pin.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model sets up a base, then sets up a turntable driven by a motor at the bottom of the base, and then sets up a combination of sliding clamping rods and sliding rods on the base. The sliding rods can pass through the arc groove of the turntable. In this way, the spacing of each clamping rod can be controlled during the rotation of the turntable driven by the motor. This not only allows the clamping rods to clamp and fix the heat sink fins to ensure their sufficient verticality, but also makes it applicable to heat sink fins of different diameters.

[0015] 2. This utility model provides a pipe guiding mechanism above the base, through which the heat dissipation pipes can pass through the hollow sleeve in the pipe guiding mechanism. Then, by rotating the adjusting sleeve, the adjusting sleeve can apply a radial thrust to the sliding pin during its rotation and movement, thereby causing the guide blocks at the end of the sliding pin to approach each other and abut against the radiator copper pipe. This guides the radiator copper pipe into the radiator fins, keeping them coaxial and preventing damage to the radiator fins. Attached Figure Description

The guide rod 6 guides the force adjustment of the clamping rods 4. An arc groove is formed inside the turntable 3 and penetrates the turntable 3, with the sliding rod 5 located within the arc groove. The arc groove allows the sliding rod 5 to experience radial force from the turntable 3 during rotation.

[0023] Please see Figure 1 , Figure 3 , Figure 4A pipe guiding mechanism 2 is provided above the base 1. The pipe guiding mechanism 2 includes a hollow sleeve 21. An adjusting sleeve 23 is threadedly connected to the outer side of the hollow sleeve 21. A sliding pin 24 is slidably connected to the side wall of the hollow sleeve 21, and the sliding pin 24 passes through the hollow sleeve 21. One end of the sliding pin 24 abuts against the adjusting sleeve 23, and the other end of the sliding pin 24 is fixedly connected to a guide block 25. A fixing bracket 22 is fixedly connected to the outer side of the hollow sleeve 21, and the end of the fixing bracket 22 is fixedly connected to the base 1. The fixing bracket 22 provides support for the pipe guiding mechanism 2. Multiple balls 26 are provided on the guide block 25. The balls 26 reduce the friction between the radiator tubes and the guide block 25. A guide pin 27 is fixedly connected to the inner wall of the hollow sleeve 21. The guide pin 27 is slidably connected to the guide block 25. A spring 28 is installed inside the guide block 25. One end of the spring 28 is fixedly connected to the guide pin 27, and the other end of the spring 28 is fixedly connected to the inner surface of the guide block 25.

[0025] The specific implementation process of this utility model is as follows: In use, the radiator fins are first placed on the base 1 and located between each clamping rod 4. Then, the motor 8 drives the turntable 3 to rotate. The arc groove on the turntable 3, in conjunction with the guide rod 6, allows the sliding rod 5 and the clamping rod 4 to move radially on the turntable 3 and approach each other until they clamp the radiator fins, keeping the radiator fins in a stable vertical state. Then, the heat dissipation pipe passes through the hollow sleeve 21 in the pipe guide mechanism 2. Then, by rotating the adjusting sleeve 23, the adjusting sleeve 23 can apply a radial thrust of the hollow sleeve 21 to the sliding pin 24 during the rotation and movement, so that the guide blocks 25 at the end of the sliding pin 24 approach each other and abut against the radiator copper pipe. This guides the radiator copper pipe into the radiator fins, keeping them coaxial and preventing damage to the radiator fins.
