A double-shaft motor 22 is arranged inside the reserved groove 20. The two lead screws 21 are both driven by the double-shaft motor 22. A slider 23 is threadedly connected to the lead screw 21. The slider 23 is slidably matched with the inner wall of the reserved groove 20. The two clamping assemblies are respectively arranged on the two sliders 23;

[0028] The double-shaft motor 22 can be used to simultaneously drive the two lead screws 21 to rotate. The two lead screws 21 can pull the two clamping assemblies to approach each other in a lead screw transmission manner, so that the two clamping assemblies push the outer frame of the fin heat exchanger to approach the center and then be clamped.

[0029] Among them, the clamping assembly includes a first support plate 24. The first support plate 24 is fixedly installed on the slider 23. A first spring 25 is fixed on the first support plate 24. The other end of the first spring 25 is fixed with a clamping plate 26. A first guide rod 27 is fixed on the clamping plate 26. The first spring 25 is sleeved outside the first guide rod 27. A first sliding groove for the first guide rod 27 to slide is formed on the first support plate 24. A battery pack 28 and a second spring 29 are arranged on the first support plate 24. The other end of the second spring 29 is fixed with a second support plate 30. A second guide rod 31 and a power supply socket 32 are arranged on the second support plate 30. A second sliding groove for the second guide rod 31 to slide is formed on the first support plate 24. The battery pack 28 is electrically connected to the power supply socket 32 through a wire.

After the power connection plug 34 is inserted into the power supply socket 32, the indicator light 33 is powered on and lights up;

[0030] When adjusting the distance between the two clamping plates 26 by using the driving component, the two clamping plates 26 can contact the outer frame of the fin heat exchanger, and the first spring 25 is compressed to ensure the stability of the outer frame during subsequent clamping. As the distance between the first support plate 24 and the clamping plate 26 continuously decreases, the power connection plug 34 can be inserted into the power supply socket 32, and the battery pack 28 supplies power to the indicator light 33, causing the indicator light 33 to turn on, so as to remind the staff to cut off the power of the double-shaft motor 22 in time. While ensuring that the two clamping components firmly clamp the outer frame, it can also avoid excessive extrusion of the outer frame. The use of the first guide rod 27 can provide a guiding function for the movement of the clamping plate 26, and the use of the second guide rod 31 can provide a guiding function for the movement of the power supply socket 32.

[0031] Working principle of the present utility model:

[0032] Place the outer frame of the fin heat exchanger between the two limiting components, so that the outer frame is in close contact with the first auxiliary roller 17. Control the double-shaft motor 22 to operate, so that the double-shaft motor 22 drives the two lead screws 21 to rotate simultaneously. The two lead screws 21 drive the two clamping plates 26 to approach each other in a screw drive manner, so that the two clamping plates 26 push the outer frame to move towards the middle until the two clamping plates 26 squeeze the two first springs 25 to contract, and the power connection plug 34 is inserted into the interior of the power supply socket 32. The battery pack 28 supplies power to the indicator light 33 until the indicator light 33 turns on. Then stop the operation of the double-shaft motor 22. At this time, the first spring 25 is in a compressed state, which can ensure that the outer frame is firmly clamped without being excessively extruded;

[0033] The staff controls the electric push rod 4 to extend, so that the electric push rod 4 pushes the air chamber 5 to a predetermined position. At this time, the air delivery pipe 10 is inserted into the corresponding heat dissipation pipe. The staff manually pushes the heat dissipation pipe so that one end of it is closely attached to the air chamber 5. Then start the air supply air pump 6 to blow air into the air chamber 5, so that the air pressure inside the air chamber 5 increases. The air enters the carrier pipe 11 along the air delivery pipe 10. The air pressure can be used to push the two pistons 13 in opposite directions. The pistons 13 push the clamping blocks 16 outwards by means of the ejector rods 15, so that the two clamping blocks 16 abut against the inner wall of the heat dissipation pipe, realizing the clamping of the heat dissipation pipe. After that, welding operation can be carried out at the connection between the heat dissipation pipe and the outer frame.

[0034] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model.
