A flange automatic welding device and method

Abstract

The invention discloses an automatic flange welding device and method thereof, belonging to the field of welding technology. The invention drives the fourth gear and the gear ring to transmit through the first motor, so that the three-jaw chuck of the feed tray rotates. When the lower part of the sixth gear transmits to the gear rod, the control end drives the three-jaw chuck to automatically position the flange. After the flange is welded, the three-jaw chuck continues to switch positions, and then the clamping assembly is driven to descend to a suitable position through the extension of the electric push rod. At this time, the double-axis motor can drive the screw and the nut to transmit, so that the clamping plate clamps the flange, and then retracts through the electric push rod. Since the position of the ball is fixed, the ball can drive the outer shell to rotate through the arc groove, so that the two flanges change positions, so that the welded flange is located on the discharge tray, so that the flange can reserve a period of time in each position conversion process, so that the flange has a certain cooling time, and the direct taking and placing can avoid hurting the staff.

[0020] A method for using a flange automatic welding device comprises the following steps:

[0021] S1. When performing welding operations, first place the flange on the material plate, then control the electric push rod to extend, so that the drum drives the shell to move downward, so that the clamping plate is located between the flanges, and then control the dual-axis motor to drive the screw to rotate, so that the screw drives the two nuts to approach each other, and then the two sliders move and drive the two clamping plates to clamp and fix the flange, and then the electric push rod retracts upward to make the shell rise, and the clamping plate lifts the flange. When the drum rises, since the ball position does not move, the ball controls the rotation of the drum through the arc groove, and the drum drives the shell to rotate, so that the clamping plate drives the flange to rotate to the other side. At this time, the electric push rod is extended again, and then the clamping assembly is operated to remove the flange fixation, so that the flange is located in the three-jaw chuck;

[0022] S2, then control the first motor to drive the fourth gear and the ring gear to drive the feeding disk to rotate, so that the position of the discharge disk and the three-jaw chuck is switched, so as to perform a cyclic feeding operation, and in the feeding process, when the sixth gear is meshed with the gear rod, the sixth gear drives the three-jaw chuck to fix the flange through the control end, when the flange is located at the welding equipment position, the welding equipment performs welding operation on the flange, and then control the second motor to drive the first gear and the second gear, the second gear and the third gear to drive, so that the two third gears drive the two fifth gears to rotate, so that the three-jaw chuck rotates and drives the flange to rotate, and the welding equipment performs annular surface welding operation of the flange, when the flange rotates, the roller is attached to the flange, when the two rollers cannot evenly contact the flange, one of the rollers drives the connecting rod to move, so that the second piston moves, and the air pressure controls the first piston and the movable rod to move, so that the pressing block moves and presses the switch to control the alarm to perform an alarm operation, so as to remind the staff to adjust the position of the flange;

[0023] S3. After the flange is welded, the feed tray rotates again. When the sixth gear meshes with another gear rod, the sixth gear drives the control end to reverse and drives the three-jaw chuck to remove the flange. At this time, the flange positions on both sides are switched again by cooperating with the clamping assembly through the lifting assembly, so that the welded flange is transferred to the discharge tray for unloading.

[0024] Compared with the prior art, the present invention provides a flange automatic welding device and method thereof, which have the following beneficial effects:

[0025] 1. The automatic welding device and method of the flange drive, through the first motor drives the fourth gear and the gear ring to transmit, the three-claw chuck of the feed plate rotates, when the lower part of the sixth gear is transmitted with the gear rod, the control end drives the three-claw chuck to automatically position the flange, when the flange is welded, the three-claw chuck continues to switch positions, and then the electric push rod is extended to drive the clamping assembly to drop to a suitable position, at this time the double-axis motor can drive the screw and the nut to transmit, so that the clamping plate clamps the flange, and then the electric push rod is retracted, because the position of the ball is fixed, the ball can drive the shell to rotate through the arc groove, so that the two flanges change positions, so that the welded flange is located on the discharge plate, so that the flange can reserve a period of time in each position conversion process, so that the flange has a certain cooling time, and avoids direct picking and placing to injure the staff, and when the upper part of the sixth gear is transmitted with another gear rod, the fixing of the flange can be automatically removed at this time, thereby improving the convenience of actual operation.

[0026] 2. The automatic flange welding device and method thereof drive the fourth gear to rotate through the first motor, and the fourth gear and the gear ring drive the feed plate to rotate, so that the three-jaw chuck performs position conversion. When the lower part of the sixth gear meshes with the gear rod, the three-jaw chuck can be driven to automatically position the flange through the control end. After positioning, when the flange contacts the roller, the second motor drives the first gear and the second gear to transmit, and the second gear and the third gear to transmit, so that the third gear and the fifth gear are transmitted, and the fifth gear drives the third rotating shaft and the three-jaw chuck to rotate, so that the entire annular surface of the flange can pass through the roller. When the force points of the two rollers are different, the force of the roller can drive the connecting rod and the second piston to move, and the first piston is controlled by air pressure to drive the movable rod to move, so that the pressing block triggers the switch to control the alarm to perform an alarm operation, thereby reminding the staff to adjust the position of the flange. This method can detect whether the flange is properly placed, thereby ensuring the accurate welding of the flange.

[0027] 3. The automatic flange welding device and method thereof drive the fourth gear and the gear ring through the first motor, so that the feed plate drives the three-jaw chuck to switch positions alternately. When the lower part of the sixth gear is in transmission with the gear rod, the control end can control the three-jaw chuck to automatically fix the flange, and after fixing, the flange continues to transfer and contact with the roller. At this time, the second motor drives the first gear and the second gear to transmit, and the second gear and the third gear to transmit, so that the third gear and the fifth gear can drive the flange to rotate, and the entire annular surface of the flange can contact the roller. When the force points are different, the roller drives the connecting rod and the second piston to move, and the movement of the first piston and the movable rod is controlled by air pressure, so that the pressing block triggers the switch to control the alarm to perform an alarm reminder operation, so that the flange position can be adjusted, and when the flange is located at the welding equipment position, the welding equipment can perform welding operations, and the first gear and the fifth gear transmission can be realized. The circumferential welding operation is now performed. After welding, when the upper part of the sixth gear meshes with another gear rod, the flange is fixed and removed, and then the clamping plate can be lowered to a suitable position by extending the electric push rod, and then the screw and nut are driven by the double-axis motor to transmit, so that the clamping plate can clamp the flange. At this time, the electric push rod lifts the shell, so that the ball drives the rotating drum and the shell to rotate through the arc groove, so that the positions of the two flanges are interchanged, and then the flange is lowered and removed and fixed by the clamping assembly. At this time, the two feeding trays are driven to load and automatically discharge the materials, so that the flange processing process can be automatically fixed, and in the welding process, annular surface welding can also be realized, and the purpose of detecting the flange can be achieved on the other side. After welding, it can also be automatically removed and fixed. Finally, the flange transfer purpose can be completed by cooperating with the lifting assembly and the clamping assembly, and then the driving assembly is used in conjunction with the gear ring to achieve the purpose of automatic loading and unloading, thereby completing continuous processing operations.

When the flange rotates, the roller 2065 is attached to the flange. When the two rollers 2065 cannot evenly contact the flange, one of the rollers 2065 drives the connecting rod 2064 to move, so that the second piston 2063 moves, and the air pressure controls the first piston 2066 and the movable rod 2068 to move, so that the pressing block 20611 moves and presses the switch 2069 to control the alarm 20612 to perform an alarm operation, thereby reminding the staff to adjust the position of the flange;

[0063] S3. After the flange is welded, the feed tray 2024 rotates again. When the sixth gear 211 meshes with the other gear rod 204, the sixth gear 211 drives the control end 210 to reverse and drive the three-jaw chuck 209 to remove the flange. At this time, the flange positions on both sides are switched again by cooperating with the clamping assembly 302 through the lifting assembly 301, so that the welded flange is transferred to the discharge tray 212 for unloading.
