[0040] Specifically, when the motor 3 rotates forward, the ball 102 can rotate, and through the cooperation of the ball 102 and the gas, the I-shaped steel can be welded continuously and uniformly, and the gas can replace the elastic member to adjust the distance.

[0041] In another embodiment, the one-way mechanism 10 comprises two slide rods 103 horizontally inserted into the connecting rod 7, the two slide rods 103 being symmetrically arranged about the welding head 9, an extension rod 101 being fixedly connected to the slide rod 103, the extension rod 101 being arranged close to the base 1, a ball 102 being rotatably arranged at one end of the extension rod 101 away from the connecting rod 7, a rotating shaft 104 being fixedly connected to the center of the ball 102, one end of the rotating shaft 104 being rotatably arranged in the extension rod 101, a rotating rod 105 being rotatably arranged on the outer wall of one end of the rotating shaft 104, and a trapezoidal rod 106 being slidingly arranged in the extension rod 101 above the rotating shaft 104.

[0042] The air jet mechanism 11 comprises an air jet port 111, which is arranged on one side wall of the extension rod 101 close to the base 1. A sliding groove 113 is arranged in the extension rod 101. The trapezoidal rod 106 is slidingly arranged in the sliding groove 113. A guide groove two 112 is arranged on the inner wall of the sliding groove 113 close to the air jet port 111, and the guide groove two 112 is communicated with the air jet port 111. A guide groove three 115 is arranged on the inner wall of the sliding groove 113 away from the air jet port 111, and the guide groove three 115 is communicated with the guide groove one 83. A connecting groove 114 is arranged on the trapezoidal rod 106. A top rod 116 is fixedly connected to the upper end of the trapezoidal rod 106. A magnetic plate 117 is abuttingly arranged on the top rod 116. The magnetic plate 117 is slidingly arranged in the extension rod 101. A magnetic block 118 is abuttingly arranged on the end of the magnetic plate 117 away from the guide groove two 112, and the magnetic block 118 is fixedly connected to the connecting rod 7.

[0043] The rotating rod 105 is annularly and equidistantly provided with a plurality of rotating rods.

[0044] The end of the magnetic plate 117 close to the top rod 116 is provided with an inclined sliding surface.

[0045] The end of the magnetic plate 117 abutting the magnetic block 118 has opposite polarity.

[0046] Specifically, when the motor 3 reversely rotates, the ball 102 cannot rotate, and can polish the welding part. At the same time, the trapezoidal rod 106 will be pressed upward. Part of the gas drawn in by the air pump 6 is sprayed out of the air jet port 111 to blow and clean the polishing debris. The gas can blow the extension rod 101 outward to prevent the distance from being too close during polishing, causing damage to other parts of the I-shaped steel or the welding head 9.

[0047] Working principle: when using the device, first clamp the I-shaped steel on both sides by the clamping assembly 4. Then adjust the position of the I-shaped steel by the electric push rod 2 so that the part to be welded is in the middle. Then start the air pump 6. The air pump 6 draws external air into the cavity 81. The plug rod 82 will move towards the base 1 under the push of the gas, so that the ball 102 abuts against the I-shaped steel. At this time, the welding head 9 can weld the I-shaped steel. Then start the motor 3 to rotate the I-shaped steel, so that the I-shaped steel can be continuously welded around. Through the cooperation of the ball 102 and the gas, the welding head 9 can also automatically adjust the distance from the I-shaped steel in time when the I-shaped steel is rotating, preventing the welding head 9 from being pressed against the I-shaped steel. The gas can replace the elastic member to adjust the distance. The gas introduced into the sliding groove 113 can also replace the elastic member to press the trapezoidal rod 106 downward, preventing the elastic member from being fatigued.

[0048] When the welding is good, the air pump 6 is closed, the welding is moved to one of the ball 102 through the electric push rod 2, and then the air pump 6 is opened. The air pump 6 is closed to prevent the welding head 9 and the ball 102 from generating excessive friction with the I-shaped steel during movement. Then the motor 3 is reversed, and the I-shaped steel is reversed. When the I-shaped steel is reversed, the ball 102 is in contact with the I-shaped steel, so it is also reversed. At this time, the rotating shaft 104 and the rotating rod 105 are also reversed, so that the trapezoidal rod 106 will block the rotating rod 105 from continuing to rotate, and the ball 102 will no longer rotate, so that the welding can be polished. At the same time, the trapezoidal rod 106 will be squeezed upward, the connecting groove 114 will be connected with the guide groove 112, and the air pump 6 will suck in part of the gas from the air outlet 111, which will blow away the polishing debris and prevent it from accumulating on the surface of the I-shaped steel. When the trapezoidal rod 106 moves upward, the top rod 116 will squeeze the magnetic plate 117 and move it away from the magnetic block 118. After the magnetic plate 117 moves away from the magnetic block 118, the magnetic force between the magnetic plate 117 and the magnetic block 118 will decrease, and the gas will blow the extension rod 101 outward, so that the polished ball 102 can extend outward, and the other ball 102 and the welding head 9 will be farther away from the I-shaped steel, preventing the polishing from being too close to the other parts of the I-shaped steel and causing damage to the welding head 9.
