A comprehensive intelligent welding system

Abstract

The present invention discloses an all-round intelligent welding system, which relates to the technical field of intelligent welding. A motor is started to drive the pipe fitting to be squeezed toward the limit piece while being clamped, so that the two pipe fittings can be clamped to a predetermined position to prevent the pipe fitting from deviating and affecting the welding. When the two pipe fittings are clamped to the predetermined position, two driving sources are started to make the two pipe fittings move away from each other, and then the electric telescopic rod is started to drive the limit piece to move downward, so that the limit piece will no longer limit the pipe fittings. Then the two pipe fittings are fitted together and welding is performed at this time. At the same time, the motor is started to drive the two pipe fittings to rotate synchronously, so that the two pipe fittings rotate one circle to complete the welding. After the temperature drops, the driving source is started to reverse to drive the limit column to be limited, and then the electric telescopic rod is started to drive the limit piece to reset. Then the motor is started to reverse to drive several clamping parts to release the clamping of the pipe fitting. At the same time, the rotation of the motor drives several guide wheel parts to continuously beat the pipe body to test the welding effect of the pipe body.

The threaded sleeves 36 are all rotatably connected to the protective shell 32, and the threaded sleeves 36 are respectively threadedly connected to the threaded columns 37 in a one-to-one correspondence. The threaded columns 37 are all slidably connected to the protective shell 32, and a clamping member 38 is provided on each end of the threaded columns 37 away from the threaded sleeves 36. The starting motor 21 drives the first gear 22 to rotate, so that a second gear 23 rotates, drives the transmission shaft 24 to rotate, so that the four second gears 23 rotate, and drives the four gear rings 33 to rotate, so that the four helical gear rings 34 Rotation drives the second bevel gears 35 to rotate, causing the threaded sleeves 36 to rotate, driving the threaded columns 37 to slide, causing the clamping members 38 to slide, so that the pipe 9 is gradually clamped. At the same time, when the pipe 9 is welded, the motor 21 is started to drive the gear ring 33 to rotate. At this time, since the threaded columns 37 cannot continue to slide due to clamping, the rotation of the gear ring 33 drives the second bevel gears 35 to rotate according to the axis of the pipe 9, causing the threaded sleeves 36 to rotate, driving the protective shell 32 to rotate, so that the two pipes 9 rotate synchronously.

When the transmission shaft 24 rotates, it can drive the two first telescopic members 25 to rotate, so that the two first bevel gears 26 rotate, driving the two The third bevel gear 411 rotates, causing the bidirectional spring telescopic member 412 to rotate, driving the fourth bevel gear 413 to rotate, causing the fifth bevel gear 421 to rotate, driving the rotating rod 422 to rotate, causing the multiple connecting members 423 to rotate, and driving the multiple guide wheels 424 to rotate. The multiple guide wheels 424 continuously apply force to the pipe fittings 9, so that the two pipe fittings 9 are close to each other, causing the pipe fittings 9 to squeeze the limit member 82. At the same time, after the welding of the pipe fittings 9 is completed, the reverse rotation of the motor 21 drives the multiple guide wheels 424 to continuously beat the pipe body to test the welding effect of the pipe body.

[0047] At this time, the pipe 9 is squeezed toward the limiter 82 while being clamped, so that the pipe 9 can be clamped to a predetermined position, preventing the pipe 9 from deviating and affecting welding;

[0048] After the two pipe fittings 9 are clamped to the predetermined position, the two driving sources 51 are started to drive the two bidirectional threaded rods 52 to rotate, so that the two clamping assemblies 3 move away from each other, so that the two pipe fittings 9 move away from each other, and then the electric telescopic rod 81 is started to drive the limiter 82 to move downward, so that the limiter 82 will no longer limit the pipe fitting 9, and then the two driving sources 51 are started to reverse, so that the two clamping assemblies 3 move closer to each other, driving the two pipe fittings 9 to fit together, at this time the manipulator 6 drives the welding gun 7 to weld the two pipe fittings 9, and at the same time the motor 21 is started to drive the gear ring 33 to rotate. At this time, since the several threaded columns 37 cannot continue to slide due to clamping, the rotation of the gear ring 33 drives the several second bevel gears 35 to rotate according to the axis of the pipe fitting 9, so that the several threaded sleeves 36 rotate, drive the protective shell 32 to rotate, so that the two pipe fittings 9 rotate synchronously, by setting the speed and number of rotations of the motor 21, the two pipe fittings 9 rotate one circle, and the welding is completed by the welding gun 7;

[0049] After the temperature drops, the driving source 51 is started to reverse and drive the two clamping components 3 away from each other, so that the limit column 39 is limited, and then the electric telescopic rod 81 is started to drive the limit member 82 to reset, and then the motor 21 is started to reverse and drive the several clamping members 38 to release the clamping of the pipe 9.
