In order to facilitate steering, the welding rod is prevented from interfering with the first reversing toothed plate 620 or the second reversing toothed plate 630, the lower end of the welding rod faces the axis of the rotating rod, and the axis of the lower end of the welding rod rotates coincides with the axis of the rotating rod.
The steel plate automatic welding equipment of the embodiment is used as follows:
when the automatic steel plate welding equipment is used for welding, a circular-ring-shaped strip conveying method is adopted, namely, the end of a welding rod continuously moves in a circular ring shape and continuously moves, so that the automatic steel plate welding equipment is used for welding a steel plate with a large thickness.
During welding, a steel plate to be welded is fixed on a horizontal support plate 110 of the workbench 100, the lower end of a welding rod faces to the axis of the rotating rod and is close to a welding seam, a set inclination angle is formed between the welding rod and the horizontal plane, and the plane where the axis of the welding rod is located in the vertical direction is parallel to the plane where the welding seam is located in the vertical direction.
When the welding rod is electrified, the driving motor is started, the driving motor drives the screw rod to rotate, the mounting frame 211 moves rightwards, the rotating shaft 229 rotates anticlockwise, the first wheel shaft 332 rotates anticlockwise, the input rolling cone 331 drives the output rolling cone 333 to rotate through the cone ring 335, further the second wheel shaft 334 drives the longitudinal gear 242 to rotate clockwise, the longitudinal wheel shaft drives the longitudinal rack 244 to move downwards, the longitudinal rack 244 drives the axial moving rod 203 to move downwards, the driving rod 420 moves downwards synchronously, the first control gear 431 on the driving rod 420 moves downwards along the first control toothed plate 410 and rotates, the rotation of the first control gear 431 can drive the second control gear 433 to rotate, further the second control gear 433 can drive the second control toothed plate 437 to slide on the first plate section 452 of the control frame 450, the second control toothed plate 437 can drive the welding vertical shaft to slide along the long hole 453 of the first plate section 452, and the welding vertical shaft approaches to the driving rod 420, in the process, the electrode is continuously consumed, and the electrode moves downward and approaches the driving rod 420, so that the small end of the newly produced electrode is always located near the axis of the driving rod 420.
And because the third control gear 435 is fixed on the welding vertical shaft, and the third control gear 435 is meshed with the third control toothed plate 439, the welding vertical shaft can also rotate while sliding in the long hole 453, the rotation of the welding vertical shaft can drive the connecting arm 443 and the rotating sleeve 445 to rotate, the clamping shaft 510 in the rotating sleeve 445 can also move along with the rotating sleeve 445, but because of the restriction of the direction adjusting component and the rotating fit between the rotating sleeve 445 and the clamping shaft 510, the rotation motion of the rotating sleeve 445 is blocked by the rotating fit between the rotating sleeve 445 and the clamping shaft 510 and cannot be transmitted to the clamping shaft 510, so that the welding rod clamping piece 500 only can perform translation motion and can rotate around the welding rod vertical shaft 441 under the condition that the self can not rotate, the plane of the axis of the welding rod in the vertical direction is always parallel to the plane of the welding rod in the vertical direction, the lower end part of the welding rod continuously performs circular motion, and the steel plate is moved forwards continuously, so that the welding is realized by using a circular strip conveying method, and the welding condition of the steel plate with larger thickness can be adapted. In addition, in the welding process, the extending direction of the clamping arm 520 is always the same along the extending direction of the welding seam, the inclination angle of the welding rod relative to the welding seam is always unchanged, the welding effect is favorably ensured, and when the welding rod vertical shaft 441 rotates, the rotating radius of the lower end part of the welding rod is the distance between the axis of the clamping shaft 510 and the welding rod vertical shaft 441.
When the mounting bracket 211 is going to move to the end of the stroke rightwards, the reversing half gear 610 on the lower end of the driving rod 420 is meshed with the first annular toothed plate, along with the continuous movement of the mounting bracket 211, the reversing half gear 610 can rotate for a half circle, and further the driving rod 420 and the corresponding structure on the driving rod can also rotate for a half circle, because the rotation stopping block on the reversing disc 254 is inserted into the rotation stopping elongated slot on the driving rod 420, the driving rod 420 can drive the reversing disc 254 to synchronously rotate for a half circle, and the first control toothed plate 410 on the lower bottom surface of the reversing disc 254 synchronously rotates for a half circle, so that the reversing is completed, and at the moment, the driving motor is controlled to reversely rotate, so that the welding rod is driven to return, and the welding is continuously performed.
When steel plates with different thicknesses are welded, the moving radius of the circular motion of the lower end part of the welding rod needs to be changed, the threaded section 473 of the rotating nut 472 is adjusted, the rotating nut 472 drives the rotating sleeve 445 to move in the moving long groove 444 on the connecting arm 443 through the hinged arm 475, and therefore the distance between the axis of the clamping shaft 510 and the axis of the welding rod vertical shaft 441 is adjusted; meanwhile, when the downward moving speed of the welding rod needs to be adjusted, the adjusting nut 339 on the speed reducing shell 320 is screwed, and the position of the cone ring 335 is changed by the adjusting nut 339, so that the transmission ratio between the input rolling cone 331 and the output rolling cone 333 is adjusted.
