Description

Technical Field

[0001] The present invention relates to the technical field of steel structure welding, and particularly to a welding device with an adjustable welding surface for steel structure processing. Background Art

[0002] A steel structure is a structure composed of steel materials and is one of the main types of building structures. When converting the angle of an I-shaped steel during the welding process of traditional I-shaped steel, the welding angle of the I-shaped steel is mostly manually moved and flipped to facilitate welding.

[0003] In the prior art, usually after welding one side, the steel structure is flipped by a machine, and then the other side is welded. This welding method will interrupt the continuity of welding, thereby reducing the uniformity of welding. Moreover, when continuously welding, there are uneven parts on the surface of the steel structure, and the distance between the welding assembly and the steel structure needs to be frequently adjusted, reducing the work efficiency. Summary of the Invention

[0011] As a further description of the above technical solution: The one-way mechanism includes sliding rods horizontally inserted into the connecting rod, and there are two sliding rods, which are symmetrically arranged with respect to the welding head. An extension rod is fixedly connected to the sliding rod. The extension rod is arranged close to the base. A ball is rotatably arranged at one end of the extension rod away from the connecting rod. A rotating shaft is fixedly connected to the center of the ball. One end of the rotating shaft is rotatably arranged in the extension rod. A rotating rod is rotatably arranged on the outer wall of one end of the rotating shaft. A trapezoidal rod is slidably arranged up and down in the extension rod above the rotating shaft.

[0012] As a further description of the above technical solution: The jetting mechanism includes a jetting port, which is opened on a side wall of the extension rod close to the base.

[0031] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below with reference to specific illustrations. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0032] Please refer to Figure 1 - Figure 8 An embodiment of the present invention provides a technical solution: a welding device with an adjustable welding surface for steel structure processing, including a base 1 and a fixed frame 5. There are two bases 1 arranged on the opposite sides. An electric push rod 2 is provided on the base 1, and the extending end of the electric push rod 2 is horizontally slidably arranged in the base 1. The extending end of the electric push rod 2 is fixedly connected with a motor 3, and the output end of the motor 3 is fixedly connected with a clamping assembly 4. An air extraction pump 6 is fixedly connected to the side wall of the fixed frame 5 far from the base 1. It further includes:

[0033] A connecting rod 7 for placing the welding assembly. The connecting rod 7 is arranged on the side of the fixed frame 5 close to the base 1, and a welding head 9 is provided at one end of the connecting rod 7 close to the base 1;

[0034] A dynamic mechanism 8 that can automatically move the position of the welding head 9 according to the position of the part. The dynamic mechanism 8 is arranged on the fixed frame 5;

[0035] A one-way mechanism 10 that can automatically adjust to a grinding assembly. The one-way mechanism 10 is arranged in the connecting rod 7;

[0036] And a jet mechanism 11 that can clean the grinding debris. The jet mechanism 11 is arranged in the one-way mechanism 10.

[0037] The fixed frame 5 is located on one side in the middle of the two bases 1.

[0038] Specifically, when the motor 3 rotates forward, the ball 102 can rotate. Through the cooperation of the ball 102 and the gas, when the I-beam rotates, the welding head 9 can also automatically adjust the distance from the I-beam in a timely manner, preventing extrusion between the welding head 9 and the I-beam, enabling continuous and uniform welding, and the gas can replace the elastic member to achieve distance adjustment. When the motor 3 rotates in the reverse direction, the ball 102 cannot rotate, and the welding area can be polished. At the same time, the trapezoidal rod 106 will be extruded upward. Part of the gas drawn by the air extraction pump 6 is ejected from the air jet port 111 to blow and clean the grinding debris, and the gas can blow the extension rod 101 outward, preventing the distance from being too close during grinding, causing wear to other parts of the I-beam or damage to the welding head 9.

[0039] In another embodiment provided by the present invention, the dynamic mechanism 8 includes a cavity 81 opened in the fixed frame 5. A plug rod 82 is horizontally slidably arranged in the cavity 81. The cavity 81 is communicated with the air extraction pump 6. One end of the plug rod 82 extending outside the fixed frame 5 is fixedly connected to the connecting rod 7. A first guide groove 83 communicating with the cavity 81 is opened on the plug rod 82.

[0040] Specifically, when the motor 3 rotates forward, the ball 102 can rotate. Through the cooperation of the ball 102 and the gas, when the I-beam rotates, the welding head 9 can also automatically adjust the distance from the I-beam in a timely manner, preventing extrusion between the welding head 9 and the I-beam, enabling continuous and uniform welding, and the gas can replace the elastic member to achieve distance adjustment.

[0041] In another embodiment provided by the present invention, the one-way mechanism 10 includes a slide rod 103 horizontally inserted into the connecting rod 7. There are two slide rods 103, and the two slide rods 103 are symmetrically arranged with respect to the welding head 9. An extension rod 101 is fixedly connected to the slide rod 103. The extension rod 101 is arranged close to the base 1. A ball 102 is rotatably arranged at one end of the extension rod 101 away from the connecting rod 7. A rotating shaft 104 is fixedly connected to the center of the ball 102. One end of the rotating shaft 104 is rotatably arranged in the extension rod 101. A rotating rod 105 is rotatably arranged on the outer wall of one end of the rotating shaft 104. A trapezoidal rod 106 is slidably arranged up and down in the extension rod 101 above the rotating shaft 104.

[0042] The air jet mechanism 11 includes an air jet port 111 which is opened on one side wall of the extension rod 101 close to the base 1. A chute 113 is formed in the extension rod 101. A trapezoidal rod 106 is slidably arranged in the chute 113. A second guide groove 112 is formed on the inner wall of the chute 113 close to the air jet port 111, and the second guide groove 112 communicates with the air jet port 111. A third guide groove 115 is formed on the inner wall of the chute 113 away from the air jet port 111, and the third guide groove 115 communicates with the first guide groove 83. A connection groove 114 is formed 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 abuts against the upper end of the top rod 116. The magnetic plate 117 is horizontally slidably arranged in the extension rod 101. A magnetic block 118 abuts against one end of the magnetic plate 117 away from the second guide groove 112, and the magnetic block 118 is fixedly connected to the connecting rod 7.

[0043] A plurality of rotating rods 105 are arranged at equal intervals in a ring shape.

[0044] An inclined sliding surface is arranged at the bottom of one end of the magnetic plate 117 close to the top rod 116.

[0045] The polarities of the ends of the magnetic plate 117 and the magnetic block 118 in contact with each other are opposite.

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

[0047] Working principle: When using this device, first clamp the I-shaped steels on both sides through the clamping assembly 4, and then adjust the position of the I-shaped steel through the electric push rod 2 so that the part to be welded is in the middlemost position. Then start the air pump 6. The air pump 6 pumps external air into the cavity 81. The insertion rod 82 will move towards the direction close to the base 1 under the push of the gas, so that the ball 102 can abut 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 continuous welding can be carried out around the I-shaped steel. Through the cooperation of the ball 102 and the gas, when the I-shaped steel rotates, the welding head 9 can also automatically adjust the distance from the I-shaped steel in time to prevent extrusion between the welding head 9 and the I-shaped steel, and the gas can replace the elastic member to realize the adjustment of the distance. The gas is introduced into the chute 113, and it can also replace the elastic member to squeeze the trapezoidal rod 106 downward, preventing the elastic member from generating fatigue;

[0048] After welding, turn off the air extraction pump 6. Move the welding point to one of the balls 102 through the electric push rod 2, and then turn on the air extraction pump 6. Turning off the air extraction pump 6 first prevents excessive friction from being generated between the welding head 9, the ball 102 and the I-beam during movement. Then, reverse the rotation of the motor 3, and the I-beam rotates in the reverse direction accordingly. When rotating in the reverse direction, the ball 102 abuts against the I-beam, so it will also rotate in the reverse direction. At this time, the rotating shaft 104 and the rotating rod 105 will also rotate in the reverse direction, so that the trapezoidal rod 106 will block the continuous rotation of the rotating rod 105, and the ball 102 will no longer rotate, so that the welding point can be polished. At the same time, the trapezoidal rod 106 will be squeezed upward, and the connecting groove 114 is communicated with the second guide groove 112. Part of the gas drawn in by the air extraction pump 6 is ejected from the air jet port 111 to blow and clean the grinding debris to prevent it from accumulating on the surface of the I-beam. When the trapezoidal rod 106 moves upward, the ejector rod 116 will squeeze the magnetic plate 117 and move the magnetic plate 117 away from the magnetic block 118. After the magnetic plate 117 moves away from the magnetic block 118, the suction force between the magnetic plate 117 and the magnetic block 118 will decrease, and the gas can blow the extension rod 101 outward, so that the grinding ball 102 can protrude more outward. The other balls 102 and the welding head 9 will be farther away from the I-beam, preventing excessive proximity during grinding from causing wear to other parts of the I-beam or damage to the welding head 9.

[0049] The foregoing has shown and described the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The descriptions in the above embodiments and the specification only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements fall within the scope of the present invention claimed.
