[0019] like Figure 1 As shown, this embodiment provides a fin tube welding auxiliary device, including a base 1, a screw 3, a turntable 4, and a power mechanism 5.

[0020] Specifically, a first base 11 and a third base 13 are fixedly provided on the top of the base 1 , two guide rods 14 are provided between the first base 11 and the third base 13 , and a second base 12 is further provided on the top of the base 1 , and the second base 12 is slidably provided along the two guide rods 14 .

[0021] Specifically, Figure 1-Figure 3 As shown, a square rod 31 and a connecting block 32 are respectively provided at both ends of the screw rod 3, a circle of annular groove 321 is provided on the outer periphery of the connecting block 32, and the connecting block 32 is rotatably matched with the second base 12 through the annular groove 321, a first conical block 33 is provided on the outer side of the connecting block 32, and a second conical block 131 is rotatably provided on the inner side of the third base 13, and the first conical block 33 and the second conical block 131 are arranged opposite to each other and are respectively used to insert the two ends of the light tube.

[0022] Specifically, Figure 1 , Figure 2As shown, the height of the first base 11 is lower than that of the second base 12. A groove 111 is provided on the top of the first base 11. The turntable 4 is located in the groove 111. The center of the turntable 4 is threadedly matched with the screw 3. In order to facilitate the rotation of the turntable 4, a plurality of toggle rods 41 are evenly provided on the outer periphery of the turntable 4. The toggle rods 41 point to the center of the turntable 4. The two outer walls of the turntable 4 are respectively close to the two inner walls of the groove 111. The functions of the groove 111 are to limit the turntable 4 and to avoid the toggle rods 41.

[0023] Specifically, Figure 1 , Figure 2 As shown, the power mechanism 5 includes a motor 51, two gears 52 and a limit plate 53. The two gears 52 are meshed, the output shaft of the motor 51 is connected to one of the gears 52, the square rod 31 slides through the other gear 52, the limit plate 53 is arranged on the bracket, and a limit groove 531 is arranged at the bottom of the limit plate 53. The top of the other gear 52 is arranged in the limit groove 531, and the two outer walls of the other gear 52 are respectively close to the two inner walls of the limit groove 531, and the limit groove 531 plays a role in limiting the other gear 52.

[0024] The operating principle is as follows: first rotate the turntable 4, and the motor 51 remains unstarted, because the center of the turntable 4 is threadedly matched with the screw 3, and the square rod 31 at the end of the screw 3 is restricted by the other gear 52. Therefore, when the turntable 4 rotates, the screw 3 will be prompted to move in the direction of the second conical block 131, thereby reducing the distance between the first conical block 33 and the second conical block 131 until the two ends of the light tube are fixed. Note: during the movement of the screw 3, the square rod 31 has never been separated from the other gear 52; after the light tube is fixed, stop rotating the turntable 4, turn on the motor 51, the two gears 52 rotate, and the gear 52 penetrated by the square rod 31 will prompt the square rod 31 to rotate, thereby causing the screw 3, the turntable 4, the connecting block 32, the first conical block 33, the light tube, and the second conical block 131 to rotate as a whole; when the light tube rotates slowly, the fins are welded to the light tube through the cooperation of the fin bending equipment and the welding equipment.

[0025] More specifically, Figure 4 As shown, the two side walls of the limiting plate 53 are provided with avoidance grooves 532 , and when the square rod 31 rotates, the avoidance grooves 532 are used to avoid the square rod 31 .

[0026] More specifically, Figure 1 , Figure 2As shown, a bearing mechanism 2 is also provided on the top of the base 1. The bearing mechanism 2 is located between the second base 12 and the third base 13, and is also located between the two guide rods 14. The bearing mechanism 2 includes a lifting platform 21 and an arc-shaped support plate 22. The arc-shaped support plate 22 is arranged on the top of the lifting platform 21. The power source of the lifting platform 21 can be a lifting rod driven by a cylinder, an oil cylinder or a hydraulic pressure. The lifting platform 21 is used to move the arc-shaped support plate 22 up and down, and the arc-shaped support plate 22 is used to support the light tube, thereby freeing manpower.

[0027] When in use, the staff places the light tube to be welded on the arc-shaped support plate 22, and uses the lifting platform 21 to move the light tube up to a preset position; then the distance between the first conical block 33 and the second conical block 131 is reduced until both ends of the light tube are fixed.

[0028] In summary, the present embodiment is suitable for light tubes of different lengths and diameters, and solves the technical problem in the prior art that the two clamps are fixed in position and can only clamp light tubes of one length; the arc-shaped support plate 22 of the present embodiment can support the light tube and automatically move between the first conical block 33 and the second conical block 131, and solves the technical problem in the prior art that the staff has to support the light tube with their hands.

[0029] The above embodiments are only used to illustrate the technical ideas and features of the utility model, and are not intended to be the only or limit the utility model. Those skilled in the art should understand that various changes or equivalent replacements made to the utility model without departing from the scope of the utility model are within the scope of protection of the utility model.
