Referring to Figure 1-3, a fin heat exchanger pipe penetration device includes:

Base 1, a fixed base 11 is provided above the base 1, and a number of semicircular placement grooves 12 that cooperate with each other are provided on the side wall of the base 1 and the fixed base 11 close to each other;

Fixed component 2. The fixed component 2 includes two fixed plates 21, a threaded rod 22, a motor 23, a support plate 24, a limit rod 25 and a limit plate 26. The base 1 and one side of the fixed seat 11 are both fixedly connected to the fixed plates. 21. The lower fixed plate 21 of the two fixed plates 21 is rotatably connected with a threaded rod 22. The threaded rod 22 penetrates the upper fixed plate 21 of the two fixed plates 21, and the inner wall of the fixed plate 21 is provided with a threaded rod 22. The thread is threaded with the threaded rod 22. A motor 23 is also provided on one side of the base 1. The output shaft of the motor 23 is fixedly connected to the threaded rod 22. A support plate 24 is fixedly connected to the side wall of the base 1 away from the threaded rod 22. The support plate 24 is rotatably connected to the limiting rod 25 , and the side of the fixed base 11 away from the threaded rod 22 is fixedly connected to the limiting plate 26 , and the limiting plate 26 is penetrated by the limiting rod 25 .

It is worth mentioning that when fixing the fin tube, the threaded rod 22 starts to rotate through the motor 23, so that the upper fixing plate 21 starts to move downward, driving the fixing base 11 to move downward until it fits the base 1 , at this time, several cooperating semicircular placement grooves 12 opened on the base 1 and the fixed base 11 can fully fit with multiple fin tubes, thereby fixing and clamping multiple fin tubes at the same time, and multiple fin tubes can be clamped simultaneously. When carrying out the pipe threading work, the work efficiency is greatly improved. Since the limit rod 25 always penetrates the limit plate 26, the limit plate 26 can only move vertically, which limits the fixed base 11 and prevents the fixed base 11 from rotating. .

The abutment assembly 3 includes a first bevel gear 31, a transmission rod 32, a bevel gear ring 33, two rotating rods 34, two second bevel gears 35, two third bevel gears 36 and two abutment blocks.

One end of the rotating rod 34 close to the transmission rod 32 is provided with a third bevel gear 36 with an interference fit. The two second bevel gears 35 are meshed with the two third bevel gears 36 respectively. The two rotating rods 34 are fixedly connected with a resistor. Connector 37.

It should be noted that the limit rod 25 is provided with threads, and the inner wall of the limit plate 26 penetrated by the limit rod 25 is provided with threads that match the threads on the limit rod 25, so that the fixed base 11 is vertically displaced. When the limit plate 26 is used, the limit rod 25 can be driven to rotate, thereby driving the transmission rod 32 to rotate through the first bevel gear 31 and the bevel ring 33. The transmission rod 32 passes through the two second bevel gears 35 and the third bevel gear. 36 drives the two rotating rods 34 to rotate. Among them, the limit rod 25 is located above and below the support plate 24 and is fixedly connected with a baffle 251, which can prevent the limit rod 25 from vertical displacement, so that the limit rod 25 can only move Turn.

Moreover, when the fixed base 11 is at the top and not in contact with the base 1, the two abutting plates 37 are in a horizontal position, which facilitates placing multiple fin tubes between the base 1 and the fixed base 11. The fixed base 11 is located at the bottom and the base. 1. When fitting, the two abutting plates 37 are in a vertical position, abutting both the front and rear sides of the fin tube, preventing the fin tube from being displaced during the tube penetration work, and ensuring that the fin tube is pipe threading work.

The functional principle of this utility model can be explained through the following operation methods:

When in use, multiple fin tubes are placed in several semicircular placement slots 12 on the base 1, and then the motor 23 is turned on, and the threaded rod 22 rotates, causing the fixed base 11 to move downward until the fixed base 11 is completely aligned with the base 1. Fit and turn off the motor 23. At this time, the fixed seat 11 and the semicircular placement groove 12 matching each other on the base 1 clamp and fix multiple fin tubes, so that multiple fin tubes can be threaded at the same time, which improves the Working efficiency, when the fixed seat 11 and the base 1 are completely fitted, the two abutting plates 37 will be driven to a vertical position to abut the front and rear sides of the fin tube to prevent the fin tube from being inserted into the tube. Displacement occurs and after the pipe threading is completed, the motor 23 is turned on to cause the threaded rod 22 to rotate in the opposite direction, the fixed base 11 is displaced upward and away from the base 1, and the abutting plate 37 is in a horizontal position, and multiple finned tubes can be taken out, which is easy to operate.

The above are only preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person familiar with the technical field can, within the technical scope disclosed by the present utility model, implement the present utility model according to the present utility model. Novel technical solutions and utility model concepts, including equivalent substitutions or changes, shall be covered by the protection scope of the present utility model.
