[0020] By adopting the above technical solution, the welding assembly 2 provided on the top of the base 1 is equipped with a welding gun and other related welding equipment, which can be used to weld the steel pipes. First, the two groups of steel pipes that need to be welded can be placed on the pressure roller 9, and the welding ports of the two groups of steel pipes that need to be welded can be aligned in the center. At this time, the two groups of first cylinders 4 can be used for braking, and the limiting wheels 14 rotatably connected to the side walls of the inner cavities of the two groups of first fixed frames 7 can hold the two groups of steel pipes against the two groups of steel pipes, limit the parts, and ensure their stability. At this time, the driving motor 10 can be used for output, which can drive the connecting rod 11 and the two groups of worms 12 fixedly connected on the surface to rotate, and at the same time, the worm 12 can be driven to engage. The connected worm gear 13 rotates, and because the textures of its two groups of worms 12 and the two groups of worm gears 13 are opposite, the two groups of fixed rods 8 fixedly connected by the two groups of worm gears 13 can be driven to rotate in different directions, and at the same time, the pressure roller 9 fixedly connected to the surface of the two groups of fixed rods 8 can be driven to rotate. The pressure and friction generated by the pressure roller 9 on the steel pipe can drive the steel pipe to rotate. While rotating, the output of the second cylinder 5 on the top of the support frame 3 can be used to send the cleaning piece provided at the bottom thereof to the corresponding position. The cleaning piece can be used to quickly blow off the rust and dust impurities on the surface of the steel pipe, thereby facilitating the use of the welding assembly 2 to perform complete welding processing on the welding port.

[0021] Reference Figure 1, Figure 2 and Figure 3 The cleaning parts include an air pump 6, a second fixed frame 15, a grinding wheel 16, a spray gun 17 and a telescopic hose 18. The bottom of the second air cylinder 5 is fixedly connected to the second fixed frame 15 by bolts, the inner cavity side wall of the second fixed frame 15 is fixedly connected to the grinding wheel 16 by bolts, the inner cavity side wall of the second fixed frame 15 is fixedly connected to the spray gun 17 by bolts, the top of the spray gun 17 is fixedly connected to the telescopic hose 18 by bolts, one end of the telescopic hose 18 away from the spray gun 17 movably passes through the support frame 3, one end of the telescopic hose 18 passing through the support frame 3 is fixedly connected to the air pump 6 by bolts, and the bottom of the air pump 6 is fixedly connected to the top of the support frame 3 by bolts;

[0022] By adopting the above technical solution, the output of the second cylinder 5 on the top of the support frame 3 can be used to send its second fixed frame 15 to the corresponding position, so that the grinding wheel 16 can be tightly fitted to the welding parts of the two groups of steel pipes. While the steel pipes are rotating, the grinding wheel 16 can be used to apply pressure to the welding parts of the steel pipes to grind the welding parts of the steel pipes, and impurities such as rust on the surface can be removed. At the same time, the output of the air pump 6 can be used to quickly blow away the rust, iron filings, dust and impurities ground off the welding parts of the steel pipes through the spray gun 17 fixedly connected to one end of the telescopic hose 18.

[0023] The implementation principle of a steel pipe welding device in the embodiment of the present application is as follows: a welding assembly 2 provided on the top of its base 1 is provided with a welding gun and other related welding equipment, which can be used to weld its steel pipes. First, the two groups of steel pipes that need to be welded can be placed on the pressure roller 9, and the welding ports of the two groups of steel pipes that need to be welded can be aligned in the center. At this time, the two groups of first cylinders 4 can be used for braking, and the limiting wheels 14 rotatably connected to the inner cavity side walls of the two groups of first fixed frames 7 can hold the two groups of steel pipes against the two groups of steel pipes and limit the parts to ensure their stability. At this time, the driving motor 10 can be used for output, which can drive the connecting rod 11 and the two groups of worms 12 fixedly connected on the surface thereof to rotate, and at the same time, the worm wheel 13 meshingly connected to the worm 12 can be driven to rotate. Because the textures of the two groups of worms 12 and the two groups of worm wheels 13 are opposite, the two groups of fixed rods 8 fixedly connected to the two groups of worm wheels 13 can be driven to rotate in different directions, and at the same time, the surfaces of the two groups of fixed rods 8 can be driven to be fixedly connected. The connected pressure roller 9 rotates, and the pressure and friction generated by the pressure roller 9 on the steel pipe can drive the steel pipe to rotate. While rotating, the output of the second cylinder 5 on the top of the support frame 3 can be used to send the second fixed frame 15 to the corresponding position, so that the grinding wheel 16 is closely fitted to the welding parts of the two groups of steel pipes. While the steel pipes are rotating, the grinding wheel 16 is used to apply pressure to the welding parts of the steel pipes, so that the welding parts of the steel pipes can be polished to remove impurities such as rust on the surface. At the same time, the output of the air pump 6 can be used to quickly blow off the rust, iron filings, dust and impurities polished off the welding parts of the steel pipes through the spray gun 17 fixedly connected at one end of the telescopic hose 18, so as to facilitate the complete welding processing of the welding port using the welding assembly 2. The first cylinder 4 and the second cylinder 5 can both be preferably TDA20 type, the air pump 6 can be RV-10V type blowing pump 6, and the driving motor 10 can be NEMA 17 Stepper motor, a stepper motor consists of a rotor and a stator. The rotor usually contains a magnetic pole pair, while the stator contains a drive circuit and an electromagnetic coil. The stepper motor generates a magnetic field by applying an appropriate current to the electromagnetic coil, so that the rotor rotates at a certain step angle. Controlling the magnitude and direction of the current can control the speed and direction of the motor. The rotation of the stepper motor is carried out in units of a fixed step angle, such as 1.8 degrees or 0.9 degrees, by controlling the number and frequency of pulse signals applied to the electromagnetic coil, the angle of motor rotation can be controlled, the speed can be controlled by adjusting the frequency of the pulse signal, a higher frequency usually results in a faster speed, and vice versa, the controller can adjust the frequency of the pulse signal as needed to achieve the desired speed, stepper motors are usually locked in the current position when the pulse signal input stops, because their rotors will be kept in the current position unless enough force is applied to move them, this self-locking function makes stepper motors very useful when they need to maintain position or prevent accidental movement, the overall use is simple and easy to operate, and the iron filings and dust impurities on the surface of the two sets of steel pipes that need to be welded can be quickly cleaned, and then welded and fixed, which can effectively improve the welding quality of the steel pipes and their connection strength. .
