Description

Technical Field

[0001] The invention belongs to the technical field of arc welding workbenches, and in particular relates to an industrial automated arc welding workbench and a use method thereof. Background Art

[0002] Arc welding is a welding method that uses the high temperature generated by an electric arc to melt metal and connect two metals together through filler materials. Arc welding uses a DC or AC power supply to generate a high-temperature arc, which generates arc light and heat between the electrode (welding rod or welding wire) and the workpiece, thereby partially melting the workpiece and connecting them together. During the welding process, the heat generated by the arc discharge melts the welding rod and the workpiece together, and forms a weld after condensation, thereby obtaining a strong joint.

[0003] Industrial automation refers to the general term for the information processing and process control such as measurement and manipulation of machines and equipment or production processes according to the expected goals without direct human intervention or less human intervention. It involves the technical fields of machinery, microelectronics, computers, machine vision, etc., and is a comprehensive technology. Under the conditions of industrial production automation, people only indirectly take care of and supervise the production of machines.

[0004] The automated arc welding workbench is an indispensable and important equipment in modern industrial production. It integrates automation technology, arc welding technology and precision mechanical structure, and can achieve efficient, accurate and continuous welding operations. The automated arc welding workbench automatically completes the welding process through preset welding procedures and paths without frequent manual intervention. It adopts the arc welding method, using the arc generated by the current passing through the electrode to heat and melt the surface of the workpiece, and then connects the workpiece by adding filler material.

[0005] The authorization publication number "CN112404673B" records "an arc welding workbench, comprising a rotary unit for driving a workpiece to rotate, a clamping unit connected to the rotary unit and used to clamp the workpiece, an adjustable push rod unit for pushing the workpiece toward the clamping unit, and an arc welding machine for welding the workpiece; the clamping unit comprises a clamp that rotates coaxially with the rotary unit, a disc connected to the clamp and rotates therewith, and a carbon brush that maintains contact with the disc during the rotation of the disc; the carbon brush is connected to the electrode so that the disc and the clamp are charged at the same time. Compared with the prior art, the arc welding workbench of the present invention can prevent the electrode from detaching from the workpiece, and the workpiece will not affect the welding action when rotating, thereby improving the efficiency and quality of arc welding."

[0006] The arc welding workbench of the above patent uses a connection method of connecting the workpiece with a carbon brush and a disc, so that the workpiece will not affect the welding action when rotating, thereby improving the efficiency and quality of welding. In addition, it is provided with an adjustable push rod unit and a support unit, which can be adjusted according to the shape and size of the workpiece, so that the workpiece can obtain better support and improve the stability and accuracy of welding. In addition, by increasing the contact area between the clamp and the workpiece, the occurrence of sparks can be reduced and safety can be improved. It can also achieve simultaneous assembly and disassembly of the workpiece and welding, thereby improving efficiency. In the existing arc welding workbench, during the welding process between pipe fittings, it is too dependent on manual docking of pipe fittings. When there is a height misalignment at the joint of the pipe fittings, it is very easy to reduce the welding efficiency of the pipe fittings due to the increased docking workload. At the same time, the welding effect between the pipe fittings is poor, and it is impossible to achieve a good fish scale welding effect. For this reason, we propose an industrial automation arc welding workbench and its use method. Summary of the invention

[0022] A method for using an industrial automated arc welding workbench comprises the following steps:

[0023] S1, automatic clamping:

[0024] When two pipes are inserted into the two fixed clamps and the rotating clamp, the two infrared sensors detect the pipes between the two fixed clamps and the rotating clamp, and the two infrared sensors trigger the running program in the PLC control box, power on the two third electric push rods, and the output ends of the two third electric push rods push the two rotating clamps to rotate. The two rotating clamps clamp the two pipes by approaching the two fixed clamps, thereby realizing automatic clamping of the pipes;

[0025] S2, automatic docking:

[0026] After the automatic clamping of the two pipes is completed, the PLC control box is powered on to start the two second electric push rods, the output ends of the two second electric push rods push the two lifting frames to lift, the two lifting frames drive the two rail frames to lift, the two rail frames drive the two fixed clamps and the two rotating clamps to lift, so that the two pipes are in the same horizontal plane, and at the same time, the two pushing motors are powered on to start, the output ends of the two pushing motors drive the two screw rods to rotate, the two screw rods drive the two fixed clamps to move horizontally by sliding with the two sliders, so that the two pipes are horizontally butted, the butt joint of the two pipes is located in the rotating sleeve, and the butt joint of the two pipes corresponds to the welding head, so that the two pipes are automatically butted;

[0027] S3, Circular welding:

[0028] When the two pipes are automatically butted together, the rotating motor is powered on and started, and the output end of the rotating motor drives the rotating gear to rotate. The rotating motor pushes the rotating sleeve to rotate in the ring sleeve through meshing with the inner gear ring, so that the rotating sleeve rotates in the ring sleeve through the second bearing, so that the welding head rotates around the butt joint of the two pipes. At the same time, the servo motor is powered on and started, and the output end of the servo motor drives the driving wheel to rotate. The driving wheel inserts one end of the welding wire into the welding head through rotation. The welding head is powered on to melt the welding wire at high temperature at the butt joint of the two pipes. The welding wire rotates around the butt joint of the two pipes to perform annular welding on the butt joint of the two pipes.

[0029] S4, fish scale welding:

[0030] During the process of annular welding of two pipe fittings, the first electric push rod is powered on and started. The output end of the first electric push rod contracts and pulls the pawl away from the arc-shaped ratchet bar, releasing the meshing of the pawl and the arc-shaped ratchet bar, and then releasing the restriction on the rotation of the rotating frame ring sleeve. After releasing the rotation restriction of the rotating frame and the ring sleeve, the stepper motor is powered on and started. The output end of the stepper motor drives the deflection gear to rotate unidirectionally. The deflection gear pushes the deflection half-rack to deflect by meshing with the deflection half-rack. The deflection half-rack drives the rotating frame to deflect, and the rotating frame drives the ring sleeve to deflect. When the output end of the stepper motor rotates to the maximum rotation limit, the stepper motor is triggered. The motor rotates counterclockwise, and the output end of the stepper motor drives the deflection gear to rotate in the opposite direction. The deflection gear pushes the rotating frame to rotate in the opposite direction by meshing with the deflection half rack, thereby resetting the rotating frame. When the output end of the stepper motor rotates to the minimum limit, the clockwise rotation of the stepper motor is triggered, and the output end of the stepper motor drives the deflection gear to rotate clockwise again, and then the rotating frame and the ring sleeve are driven to swing slightly through the clockwise and counterclockwise rotation of the deflection gear, so that the welding wire in the welding head can swing left and right around the joint of the two pipes, thereby fusing the welding wire to the joint of the two pipes and completing the fish scale welding of the two pipes.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] 1. In this solution, when two pipes are inserted into two fixed clamps and a rotating clamp, when two infrared sensors detect the pipes between the two fixed clamps and the rotating clamp, the two infrared sensors trigger the running program in the PLC control box, power on and start the two third electric push rods, the output ends of the two third electric push rods push the two rotating clamps to rotate, the two rotating clamps clamp the two pipes by approaching the two fixed clamps, the PLC control box powers on and starts the two second electric push rods, the output ends of the two second electric push rods push the two lifting racks to lift, and the two lifting racks drive the two rails The frame is lifted and lowered, and the two rail frames drive the two fixed clamps and the two rotating clamps to lift and lower, so that the two pipe fittings are in the same horizontal plane, and the two pushing motors are powered on and started at the same time, and the output ends of the two pushing motors drive the two lead screws to rotate, and the two lead screws drive the two fixed clamps to move horizontally by sliding with the two sliders, so that the two pipe fittings are horizontally butted, and the butt joint of the two pipe fittings is located in the rotating sleeve, and the butt joint of the two pipe fittings corresponds to the welding head, so as to realize automatic butt joint of the two pipe fittings, replace manual butt joint of the pipe fittings, reduce the butt joint workload, and improve the pipe welding efficiency.

[0033] 2. In this scheme, after the rotation restriction on the rotating frame and the ring sleeve is released, the stepper motor is powered on to start, and the output end of the stepper motor drives the deflection gear to rotate unidirectionally. The deflection gear pushes the deflection half-rack to deflect by meshing with the deflection half-rack, and the deflection half-rack drives the rotating frame to deflect, and the rotating frame drives the ring sleeve to deflect. When the output end of the stepper motor rotates to the maximum rotation limit, the stepper motor is triggered to rotate counterclockwise, and the output end of the stepper motor drives the deflection gear to rotate in the opposite direction. The deflection gear pushes the rotating frame to rotate in the opposite direction by meshing with the deflection half-rack, thereby resetting the rotating frame. When the output end of the stepper motor rotates to the maximum rotation limit, the stepper motor is triggered to rotate counterclockwise, and the output end of the stepper motor drives the deflection gear to rotate in the opposite direction. The deflection gear pushes the rotating frame to rotate in the opposite direction by meshing with the deflection half-rack, thereby resetting the rotating frame. When the end rotates to the minimum limit, the clockwise rotation of the stepper motor is triggered, and the output end of the stepper motor drives the deflection gear to rotate clockwise again, and then the deflection gear rotates clockwise and counterclockwise to drive the rotating frame and the ring sleeve to swing slightly, and the ring sleeve drives the rotating sleeve and the welding head to swing slightly, so that the welding wire in the welding head is reciprocatingly welded to the butt joint of the two pipe fittings, thereby realizing fish scale welding of the two pipe fittings. When fish scale welding is not performed, the first electric push rod pushes the ratchet pawl to engage with the arc ratchet bar, thereby locking the rotation of the rotating frame. Through the fish scale welding of the two pipe fittings, the welding effect of the industrial automation arc welding workbench is effectively improved.

[0034] 3. In this scheme, when the welding wire is welded to the joint of two pipe fittings, the rotating motor is powered on to start the rotating motor, and the output end of the rotating motor drives the rotating gear to rotate. The rotating motor pushes the rotating sleeve to climb and rotate in the ring sleeve through the engagement with the inner gear ring, so that the rotating sleeve rotates in the ring sleeve through the second bearing, so that the welding head rotates around the joint of the two pipe fittings, which is convenient for the welding wire to perform circular welding around the joint of the two pipe fittings, and effectively improves the welding efficiency of the industrial automation arc welding workbench.
