Description

Technical Field

[0001] The invention relates to the technical field of steel strip welding machines, in particular to a steel strip welding device with an interface grinding function. Background Art

[0002] The steel strip welding machine mainly uses laser welding. The laser welding machine uses high-energy laser pulses to locally heat the material in a small area. The energy of the laser radiation diffuses into the interior of the material through heat conduction to melt the material. It is a new type of welding method, mainly for thin-walled materials. During welding, two sections of steel strips are manually connected from both ends of the welding machine, and the reserved weld is welded by laser.

[0003] In the prior art, a laser welding machine is used to weld the interfaces of two sections of steel strips, and workers are mainly required to adjust the two sections of steel strips to be parallel and aligned. This manually observed alignment may be skewed or offset. Without detection and calibration, the skew rate of the steel strip welding remains high. Detection through external equipment and adjustment by workers will reduce the welding efficiency of the steel strip. Summary of the invention

The feeding roller group 42 outputs torque to transport the steel strips. During the feeding process, the air pump 51 outputs air flow to the air distribution pipe 52. One end of the steel strip is located in the arc groove 5311 at the bend of the curved elbow 531. When the steel strip is vertically spaced apart from the partition plate 532, it completely blocks several groups of air holes 5331 of the semicircular plate 533. The gas flow measured by the flow meter 534 is the gas flow located on one side of the partition plate 532. When the steel strip is offset, some of the air holes 5331 on the semicircular plate 533 are not blocked, and the gas flow measured by the flow meter 534 changes. The overall offset of the steel strip can be obtained by receiving the electrical signals of several groups of flow meters 534 through the chassis 3. The first motor 4 51 outputs torque to the first gear 452 according to the electrical signal of the chassis 3, so that the base 453 rotates around its axis, and the second motor 461 outputs torque to the second gear 462, which meshes with the tooth surface of the inner tooth groove 4631 through the second gear 462, and the slide plate 463 drives the articulated chassis 465 to slide back and forth along the tooth column 454 through the mounting ring 464. When the articulated chassis 465 moves toward the direction close to the top plate 466, the hydraulic rod 467 is compressed, and the end away from the articulated chassis 465 moves along the slide groove 4661 toward the center of the top plate 466. The point where the suction cup 468 contacts the steel belt is away from the geometric center of the steel belt. The suction cup 468 completes the absorption of the steel belt to ensure that the steel belts input on both sides are horizontally aligned. The joints of the steel belts on both sides are located on the welding table 2. The welding gun 666 slides back and forth along the slide table 65 to weld the weld first, and the grinder 665 grinds the weld.
