Technical Field

[0002] Steel structure welding is ubiquitous in the product processing industry. Welding is a common and fixed process, applicable to steel structures in many fields, such as construction, machining, and product manufacturing.

For some multi-sided, closed annular steel structures, multiple butt joints are required to ensure welding quality. Based on this, the inventor proposes a welding device for multi-sided, closed annular steel structures. This device can conveniently and efficiently perform structural butt jointing and pre-treatment based on the number of sides of the steel structure, saving time and effort and improving the efficiency of steel structure welding.

A spring 41 connects two clamping plates 39. The push plate 40 is pushed by the push rod 38 to make the clamping plate 39 slide.

[0027] Working principle: The workpiece is placed at the bottom of the positioning seat 23, supported by the support wheel 26 and limited by the positioning wheel 25. The workpiece is first positioned and corrected. When the workpiece is installed manually, the positions of the two ends of the workpiece will deviate. The position of the correction position slide 21 is controlled by the correction position electric cylinder 20, so that the correction push rod 22 is located at the end of the workpiece. The motor 3 19 works and the lead screw 3 17 rotates, which in turn moves the correction push rod 22 to push the workpiece and complete the position correction.

[0028] The workpiece is cut off at both ends, i.e., the joint area of ​​multiple workpieces is processed. The height of the support cylinder 28 is controlled by the positioning electric cylinder 29, so that the support wheel 26 presses the workpiece. Then, the motor 28 works to rotate the lead screw 29, which in turn moves the cutting slide 10 to adjust the position of the cutting wheel 13. The angle motor 11 adjusts the angle of the angle cylinder 12 to adjust the cutting angle of the cutting wheel 13, so that the joint area at the end of the workpiece is inclined. The cutting motor 14 drives the cutting wheel 13, and the angle cylinder 12 controls the height of the cutting wheel 13 to complete the cutting operation.

[0029] Based on the number of sides of the assembled steel structure, the movable clamping component is transferred to the shifting gear ring 32. Specifically, motor 3 operates, and lead screw 4 rotates, causing the transfer cylinder 42 to move below the linearly arranged movable clamping components. The transfer cylinder 42 controls the movement of the mating support 43, and the mating hole on the mating support 43 engages with the mating block 3601 on the movable frame 36 to support and fix the movable frame 36. Then, the transfer cylinder 42 moves to drive the movable clamping component, controlling the height of the movable clamping component so that the electromagnetic clamping plate 34 enters the engagement groove 3201. The electromagnetic clamping plate 34 engages in the engagement groove 3201, thus fixing the movable clamping component on the shifting gear ring 32. Then, the shifting motor 30 operates... In operation, under gear transmission, the shifting gear ring 32 rotates to change its orientation. Through the above process, the required number of movable clamping parts are transferred to the shifting gear ring 32 to form a polygon. Further, after the workpiece preparation is completed, the lifting electric cylinder 15 controls the lifting seat 16 to move, transferring the workpiece to the movable clamping parts. Specifically, the support electric cylinder 28 controls the support plate 27 to move so that the support wheel 26 is offset from the bottom of the workpiece, and the workpiece is located between the two clamping plates 39. The fixed electric cylinder 37 controls the push rod 38 to move, and the push rod 38 pushes the push plate 40 to move the clamping plates 39 and clamp and fix the workpiece. According to this process, the required number of workpieces are installed on different movable clamping parts.

[0030] The radial position of the moving frame 36 is controlled by the radial position electric cylinder 35, so that workpieces in different directions are connected to form a closed polygonal structure. Then, the robotic arm welds the workpieces to perform welding operations on the connection area.
