Detailed implementation manners

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1 - 6, an embodiment of the present invention is: a metal plate welding machine tool for machining, including a base 1, a frame 2 is fixedly connected to the top of the base 1, a cylinder 3 is fixedly connected to the top of the frame 2, an output end of the cylinder 3 is fixedly connected to a connecting plate 4, a telescopic welding torch 5 is fixedly connected to the bottom of the connecting plate 4, a clamping mechanism 6 is arranged at the bottom of the connecting plate 4, a feeding table 7 is fixedly connected to the top of the base 1, a discharging mechanism 8 is arranged at the top of the base 1, and a movable baffle mechanism 9 is arranged between the base 1 and the frame 2. The clamping mechanism 6 includes: an outer rod 601, a push rod 602, an inner rod 603, a slider 604, a pressing block 605, a telescopic rod 606, a clamping block 607, and a limiting block 608. The inner rod 603 is slidably connected to the inner wall of the outer rod 601 through an elastic member. The push rod 602 is fixedly connected to the right side of the outer rod 601. The pressing block 605 is fixedly connected to the bottom of the inner rod 603. The limiting block 608 is fixedly connected to the left side of the telescopic rod 606. The clamping block 607 is fixedly connected to the end far from the limiting block 608. A spring is arranged on the circumferential surface of the telescopic rod 606 between the pressing block 605 and the clamping block 607. The slider 604 is fixedly connected to the top of the clamping block 607. The push rod 602 is slidably connected to the surface of the slider 604. After placing the sheet material, the cylinder 3 operates, the connecting plate 4 drives the outer rod 601 to move downward, the downward movement of the outer rod 601 drives the inner rod 603 to move downward, and the downward movement of the inner rod 603 drives the pressing block 605 to contact the sheet material so as to press the sheet material. After the pressing block 605 contacts the sheet material, the outer rod 601 continues to move downward to drive the push rod 602 to move downward. The downward movement of the push rod 602 pushes the slider 604 to move through an inclined surface. The slider 604 drives the clamping block 607 to move, and the clamping block 607 clamps the sheet material from the side. The number of the clamping mechanisms 6 is four, and the four clamping mechanisms 6 are distributed in a rectangular array at the bottom of the connecting plate 4. A stop block is arranged on the right side of the top of the feeding table 7. The discharging mechanism 8 includes: a wedge block 801, a friction wheel 802, an elastic knocking rod 803, a rack one 804, a gear one 805, and a screw rod 806. The wedge block 801 is slidably connected to the top of the base 1. The rack one 804 is slidably connected to the inner wall of the base 1. The gear one 805 is rotatably connected to the inner wall of the base 1.

[0022] The friction wheel 802 is rotatably connected to the inner wall of the wedge block 801. The elastic knocking rod 803 is fixedly connected to the center of the friction wheel 802 through a connecting rod. The first rack 804 meshes with the first gear 805. The screw rod 806 is fixedly connected to the bottom of the connecting plate 4. The screw rod 806 is movably connected to the inner wall of the first gear 805. The wedge block 801 is fixedly connected to the top of the first rack 804. After welding is completed, the connecting plate 4 resets and drives the screw rod 806 to move upward. The upward movement of the screw rod 806 drives the first gear 805 to rotate through the non-self-locking spiral groove on its surface. The rotation of the first gear 805 drives the first rack 804 to move. The first rack 804 drives the wedge block 801 to push the sheet material to move. However, the sheet material is blocked by the stopper on the material placing table 7, and the sheet material can only slide and lift along the slope direction of the wedge block 801 to facilitate subsequent material taking. At the same time, the friction wheel 802 frictions with the sheet material and rotates itself. The rotation of the friction wheel 802 drives the elastic knocking rod 803 to rotate and knock the sheet material, thereby shaking off the welding slag.

[0023] Working principle: After placing the sheet material, the air cylinder 3 operates. The connecting plate 4 drives the outer rod 601 to move downward. The downward movement of the outer rod 601 drives the inner rod 603 to move downward. The downward movement of the inner rod 603 drives the pressing block 605 to contact the sheet material, thereby pressing the sheet material tightly. After the pressing block 605 contacts the sheet material, it compresses the outer rod 601 to continue moving downward and drives the push rod 602 to move downward. The downward movement of the push rod 602 pushes the slider 604 to move through the inclined surface. The slider 604 drives the clamping block 607 to move. The clamping block 607 clamps the sheet material from the side.

[0024] After welding is completed, the connecting plate 4 resets and drives the screw rod 806 to move upward. The upward movement of the screw rod 806 drives the first gear 805 to rotate through the non-self-locking spiral groove on its surface. The rotation of the first gear 805 drives the first rack 804 to move. The first rack 804 drives the wedge block 801 to push the sheet material to move. However, the sheet material is blocked by the stopper on the material placing table 7, and the sheet material can only slide and lift along the slope direction of the wedge block 801 to facilitate subsequent material taking. At the same time, the friction wheel 802 frictions with the sheet material and rotates itself. The rotation of the friction wheel 802 drives the elastic knocking rod 803 to rotate and knock the sheet material, thereby shaking off the welding slag.

[0025] Please refer to Figures 1 - 6, on the basis of the above embodiments, in another embodiment of the present invention, the movable baffle mechanism 9 includes: a guard plate 901, a connecting angle steel 902, a guide block 903, a bidirectional threaded rod 904, a motor 905, a transmission belt 906, a second rack 907, a second gear 908, a scraper 909, and a brush rod 910. The bidirectional threaded rod 904 is rotatably connected to the inner wall of the frame 2. The guide block 903 is threadedly connected to the circumferential surface of the bidirectional threaded rod 904. The connecting angle steel 902 is fixedly connected to the bottom of the guide block 903. The guard plate 901 is fixedly connected to the right side of the connecting angle steel 902. The motor 905 is fixedly connected to the top of the frame 2 through a clamping block. The bidirectional threaded rod 904 is drivingly connected to the output end of the motor 905 through the transmission belt 906. An observation window is provided on the left side of the guard plate 901. When the cylinder 3 is started, the motor 905 operates accordingly and drives the bidirectional threaded rod 904 to rotate through the transmission belt 906. The spiral grooves on the surface of the bidirectional threaded rod 904 cause the two guide blocks 903 to move closer to the center, thereby driving the two guard plates 901 to close to prevent welding slag from splashing. The second rack 907 is fixedly connected to the bottom right side of the guard plate 901. The second gear 908 is rotatably connected to the top of the base 1. The scraper 909 is fixedly connected to the top of the base 1. The brush rod 910 is fixedly connected to the top of the second gear 908. The second gear 908 meshes with the second rack 907. The scraper 909 contacts the right side of the guard plate 901. The brush rod 910 contacts the guard plate 901. After the welding operation is completed, the motor 905 rotates in reverse, causing the guide blocks 903 on the bidirectional threaded rod 904 to separate, and the guard plate 901 opens accordingly, causing the scraper 909 to scrape the observation window for preliminary cleaning. At the same time, the movement of the guard plate 901 drives the second rack 907 to move, the second rack 907 drives the second gear 908 to rotate, and the second gear 908 drives the brush rod 910 to rotate to brush and wash the observation window on the guard plate 901, further improving the cleaning effect.

[0026] Working principle: When the cylinder 3 is started, the motor 905 operates accordingly and drives the bidirectional threaded rod 904 to rotate through the transmission belt 906. The spiral grooves on the surface of the bidirectional threaded rod 904 cause the two guide blocks 903 to move closer to the center, thereby driving the two guard plates 901 to close to prevent welding slag from splashing. After the welding operation is completed, the motor 905 rotates in reverse, causing the guide blocks 903 on the bidirectional threaded rod 904 to separate, and the guard plate 901 opens accordingly, causing the scraper 909 to scrape the observation window for preliminary cleaning. At the same time, the movement of the guard plate 901 drives the second rack 907 to move, the second rack 907 drives the second gear 908 to rotate, and the second gear 908 drives the brush rod 910 to rotate to brush and wash the observation window on the guard plate 901, further improving the cleaning effect.
