Description

Technical Field

[0001] The present invention relates to the technical field of automated welding, and specifically to a welding device for tower manufacturing with surface pretreatment function. Background Art

[0002] Towers are widely used in fields such as electric power and communication, and are important infrastructure. A tower is usually composed of multiple components, and welding is one of the key technologies to achieve the connection of these components. Its quality is directly related to the structural stability and safety of the tower, and is also closely related to people's normal life. Once an accident occurs, the consequences will be unthinkable.

[0003] Towers are usually made by welding, and manual welding is one of the most commonly used methods. However, manual welding has low efficiency and unstable quality: Manual welding has a high labor intensity and a slow welding speed, making it difficult to meet the needs of large-scale production. Moreover, the welding quality is greatly affected by the technical level and working state of the workers, and problems such as welding position deviation and uneven weld seams are likely to occur, resulting in uneven quality of the towers. There are deficiencies in the automated welding system. Although some early automated welding systems can improve the efficiency of batch standardized welding work, for components of towers that are non-standard and have no fixed parameters due to different application scenarios, it is often difficult to adapt to the changes of the workpieces, and the specific conditions of the welding parts are also different. This leads to a certain degree of safety risks in the welded workpieces. Summary of the Invention

[0004] The purpose of the present invention is to provide a welding device for tower manufacturing with surface pretreatment function to solve the problems raised in the prior art.

[0005] To achieve the above object, the present invention provides the following technical solution: The welding device includes a first working bed and a second working bed. A welding machine box is arranged on the first working bed. A swing arm is rotatably connected to the first working bed. A moving arm is arranged at one end of the swing arm away from the first working bed. A welding frame is arranged on the moving arm. A plurality of welding guns are arranged on the welding frame. Each welding gun is electrically connected to the welding machine box through a wire. A docking frame is arranged on the first working bed. The docking frame is rotatably connected to the first working bed. A micro-grinding component is arranged on the welding frame. A sliding heater is arranged on the welding frame. A heat transfer wheel is arranged on the sliding heater. A plurality of grinding blocks are arranged on the heat transfer wheel. A vibrator is arranged on the second working bed. A swing frame is arranged at the output end of the vibrator. A controller is arranged on the first working bed. The controller is electrically connected to the first working bed and the second working bed through a wire. During processing, first input the welding point program into the controller. Place the tower frames to be docked in the docking frame and the swing frame respectively. The docking frame works to weld the tower. During the docking process, the vibrator drives the swing frame to vibrate, cooperate with the heat transfer wheel to preheat the welding part, and use the cooperation of vibration and grinding blocks to remove the surrounding impurities. After the docking frame completes the docking, start the welding frame. Use the cooperation between the swing arm and the moving arm to weld the welding part. Before welding, use the signal transmitted by the docking frame to polish the welding surface with the micro-grinding component. Then start the welding gun on the welding frame to weld the welding part. After welding, remove the tower or move the welded tower and wait for the next stage of welding.

[0006] A sliding servo is arranged inside the swing arm. A rotating seat is arranged on the first working bed. The output end of the sliding servo is connected to the rotating seat. A moving servo is arranged on the moving arm. The output end of the moving servo is connected to one end of the swing arm away from the sliding servo. A rotating servo is arranged at one end of the swing arm away from the moving servo. The welding frame is arranged at the output end of the rotating servo. The control program controls the position of the welding frame by controlling the moving servo and the sliding servo, and controls the attitude of the welding frame through the rotating servo. Then when reaching the welding point, the welding gun on the welding frame will weld the set position, and the power is supplied by the welding machine box.

[0007] The welding frame includes a support cover and a connecting seat. A plurality of welding seats are arranged on the support cover. Each welding gun is respectively connected to the corresponding welding seat. An adjusting knob is rotatably connected to the welding seat. The adjusting knob abuts against the welding gun. The support cover is slidably connected to the connecting seat. The connecting seat is connected to the output end of the rotating servo. An adaptive cylinder is arranged on the connecting seat. The output end of the adaptive cylinder is connected to the support cover. Before welding, adjust the position of the welding gun, and then rotate the adjusting knob to fix the position of the welding gun. During welding, start the adaptive cylinder, and the adaptive cylinder will drive the connecting seat to approach the iron frame to compensate for the welding depth.

[0008] A ranging frame is slidably mounted on the support cover. A ranging box is provided on the support cover. The ranging frame is embedded in the ranging box and is slidably connected to the ranging box. A ranging switch is provided in the ranging box. The ranging switch is in sliding contact with the ranging frame. The ranging switch is a spring switch. The ranging switch is electrically connected to the welding machine case and the controller through wires. During the process of waiting for the welding gun to approach the iron tower, the ranging frame will abut against the iron tower and gradually move closer to the inside of the ranging box until the ranging frame triggers the ranging switch. At this time, an electrical signal is transmitted to the control box, and the control box controls the welding machine case to work. At this time, the welding gun will be in the welding state, and the spring in the ranging box ensures timely detachment after welding is completed. If the ranging switch is disconnected, the welding gun will stop working at this time to avoid accidents.

[0009] A rotating motor is provided on the welding seat. A rotating wheel disc is provided at the output end of the rotating motor.

The swinging frame is rotatably connected to the welding seat. When welding, the stability and firmness of single straight-line welding are insufficient. At this time, it is necessary to start the rotating motor. The rotating motor will drive the rotating wheel disc to rotate. The sliding telescopic rod on the rotating wheel disc will swing, driving the swinging frame to slide on the welding seat, thereby indirectly driving the welding gun to swing, making the welding track a dense "S"-shaped welding track, so that the welding points at the welded part of the iron tower are more reliable.

[0010] The micro-grinding assembly includes a sweeping motor and a sweeping frame. The sweeping frame is rotatably connected to the support cover. Teeth are provided on the sweeping frame. A sweeping gear is provided at the output end of the sweeping motor. The sweeping gear meshes with the teeth on the sweeping frame. A grinding motor is provided on the sweeping frame. A grinding wheel is provided at the output end of the grinding motor. When the docking frame transmits docking information, the docking frame drives the two-sided iron towers to generate a gap with the same diameter as the grinding wheel. Subsequently, the sweeping motor is started. The sweeping motor will drive the sweeping frame to rotate. The sweeping motor drives the sweeping frame to approach the docking surface. The grinding motor rotates, driving the grinding wheel to rotate, thereby grinding the welded part. This process needs to remove the generated oxide layer and also level the welding surface to avoid the problem of welding bubbles during welding.

[0011] The docking frame includes a feeding die and a discharging die. There are multiple locking devices on the feeding die. A sliding hydraulic rod is arranged on the feeding die.

After waiting for the locking devices on the feeding die to lock the iron tower, start the sliding hydraulic rod. The sliding hydraulic rod drives the feeding die to approach the discharging die. After triggering the docking switch, move backward again to generate a grinding weld. After waiting for the micro-grinding assembly to complete processing, for this docking, after the docking switch is triggered, release the welding signal. After completing the welding of one side, start the docking motor. The docking motor will drive the iron tower to rotate as a whole to perform the welding of the second side.

[0012] A calibration component is arranged on the discharging die. The calibration component includes a laser module and a laser receiver. The laser module and the laser receiver are electrically connected to the controller through wires. A correcting hydraulic rod is arranged on the first working bed. The output end of the correcting hydraulic rod is hinged to the discharging module. During the welding process, due to heat accumulation, the workpiece may cause problems such as fatigue deformation of the metal. Start the laser module and the laser receiver. When deformation occurs, the laser die and the laser receiver will be blocked and stop working. At this time, start the correcting hydraulic rod to adjust the iron tower, so as to counteract the problems of welding cracking and workpiece deformation until each laser module and laser receiver works normally.

[0013] The sliding heater includes a heater and a heat transfer box. The heater is arranged in the heat transfer box. A heat transfer rack is also arranged in the heat transfer box.

Both ends of the reset scroll respectively abut against the transmission shaft and the heat transfer wheel. During the welding process, the heater works. The generated heat is transferred to the heat transfer wheel through the heat transfer rack. Then the heat transfer wheel comes into contact with the iron tower workpiece and cooperates with the vibrator to remove the surrounding impurities. At the same time, during this process, the hardness and softness of the iron tower can also be detected, and through manual intervention, the welding power can be adjusted to adapt to the current welding work.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. The present invention adopts an automatic docking technical means.
