Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 1 and 2, the technical scheme of the rapid welding positioning device for metal plates provided by the utility model comprises a supporting leg 1, wherein a welding table 2 is fixedly installed on the supporting leg 1, a movable chute 3 is arranged on the welding table 2, a positioning mechanism 5 is arranged at the bottom of the welding table 2, pressing mechanisms 6 are fixedly installed at two ends of a positioning cross beam 502, and metal frames can be pressed and positioned on metal plates with different widths through the cooperation of the positioning mechanism 5 and the pressing mechanisms 6, so that the welding operation on the metal plates is facilitated.

As shown in fig. 2 and 3, the positioning mechanism 5 includes a positioning rod 504 fixedly mounted at the bottom of the welding table 2, a sliding sleeve 503 is slidably mounted on the positioning rod 504, a positioning beam 502 is fixedly mounted on the sliding sleeve 503, a first screw rod 505 and a second screw rod 506 are arranged between the positioning rods 504, the first screw rod 505 and the second screw rod 506 are fixed together, screw nuts 507 are arranged on the first screw rod 505 and the second screw rod 506, the screw nuts 507 are fixedly mounted at the middle position of the positioning beam 502, positioning support legs 501 are fixedly mounted at the bottom of the welding table 2, a crank 4 is arranged at the tail end of the second screw rod 506, and the directions of threads on the first screw rod 505 and the second screw rod 506 are opposite.

Specifically, rotation of the crank 4 is transmitted to the first screw 505 and the second screw 506, so that the screws start to rotate. As the first screw 505 and the second screw 506 rotate, they further drive the screw nut 507 connected thereto to slide back and forth. The front-back sliding of the screw nut 507 directly affects the pressing mechanism 6 on the positioning beam 502, so that the pressing frame 601 moves back and forth. By this back and forth sliding, the distance between the pressing frames 601 can be adjusted, thereby achieving accurate positioning of the plates of different widths.

As shown in fig. 2 and 4, the pressing mechanism 6 includes a positioning housing 603 fixedly mounted at two ends of the positioning beam 502, a pressing frame 601 is slidably mounted in the positioning housing 603, a driving rack 602 is fixedly mounted on the pressing frame 601, a movable shaft 605 is rotatably mounted on one side of the driving rack 602, a driving gear 604 is fixedly mounted on the movable shaft 605, a worm wheel 606 is fixedly mounted at the tail end of the movable shaft 605, a worm 608 is rotatably mounted below the worm wheel 606, a telescopic transmission shaft 607 is arranged on the worm 608, a hand wheel 609 is fixedly mounted at one end of the telescopic transmission shaft 607, a sliding groove is formed in the positioning housing 603, and the pressing frame 601 is slidably mounted on the positioning housing 603 through the sliding groove.

Specifically, when the operator turns the hand wheel 609, this action is transmitted through a mechanical transmission mechanism, which first causes rotation of the telescoping transmission shaft 607. The telescopic transmission shaft 607 further drives the worm 608 to rotate during rotation. Once the worm 608 begins to rotate, it engages the worm gear 606 such that the worm gear 606 also begins to rotate. The rotation of the worm wheel 606 is transmitted to the movable shaft 605, and the movable shaft 605 rotates. Rotation of the movable shaft 605 in turn drives rotation of the drive gear 604. The rotational motion of the drive gear 604 translates into up and down movement of the drive rack 602. When the rack 602 is driven to move downward, it pushes the pressing frame 601 to move downward together. The lowering action of the pressing frame 601 causes the metal frame to be pressed and positioned on the metal plate, thereby facilitating the welding operation of the metal plate and ensuring the stability and accuracy of the welding process.

Working principle: when the welding device is used, firstly, a metal plate is placed on the welding table 2, then, a metal frame is placed on the metal plate, after the metal frame is placed on the metal plate, the crank 4 can be rotated, after the crank 4 is rotated, the first screw rod 505 and the second screw rod 506 are driven to rotate, after the crank 4 is rotated, the first screw rod 505 and the second screw rod 506 can drive the screw rod nut 507 to slide back and forth, after the screw rod nut 507 slides back and forth, the pressing mechanism 6 on the positioning cross beam 502 is driven to slide back and forth, so that the pressing frames 601 are mutually close to each other and move to the upper side of the metal frame body, after the pressing frames 601 move to the upper side of the metal frame body, the hand wheel 609 can be rotated, after the hand wheel 609 is rotated, the telescopic transmission shaft 607 can drive the worm 608 to rotate, after the worm 608 rotates, the worm wheel 606 can drive the worm 606 to rotate, after the movable shaft 605 can drive the driving gear 604 to rotate, the driving rack 602 to lift, and when the driving rack 602 descends, the pressing frames 601 move downwards, so that the metal plate is pressed on the metal plate is conveniently welded.
