[0040] In the embodiment of the present invention, in the initial state, the two cylinders 405 are in a contracted state, the end of the L-shaped clamping plate 108 is away from the end surface of the tooling plate 106, and when the aluminum alloy extruded profile on the upper end of the tooling plate 106 is clamped, the two cylinders 405 extend, and under the guidance of the sliding groove 101, the two cylinders 405 drive the two sliding blocks 102 to move respectively, and the two sliding blocks 102 drive the two locking blocks 505 and two of the opposite guide rods 101 to move, and the two opposite guide rods 101 drive the two L-shaped moving rods 402 to move, and the two L-shaped moving rods 402 pass through the inclined push groove 401. 3 and the driving shaft 404 drive the other two relative guide rods 110 to move, thereby making the four guide rods 110 move toward each other synchronously, and the guide rod 110 drives the L-shaped clamping plate 108 to rotate through the connecting rod 111 until the L-shaped clamping plate 108 cooperates with the end face of the tooling plate 106 to clamp and fix the aluminum alloy extruded profile, at which time the locking block 505 coincides with the locking groove 507, under the guiding action of the sliding groove 2 503, the compression spring 1 506 pushes the sliding block 2 504 to move, and the sliding block 2 504 drives the locking block 505 to insert into the locking groove 507, and the locking groove 507 restricts the movement of the locking block 505, and the locking block 505 restricts the sliding block 1 505 02 moves, the sliding block 102 limits the movement of the guide rod 110, thereby limiting the rotation of the L-shaped clamping plate 108, thereby limiting the L-shaped clamping plate 108 from loosening the aluminum alloy extruded profile. When the aluminum alloy extruded profile needs to be loosened, the guide slider 105 drives the tooling plate 106, the sliding block 102, the sliding block 204 and the locking block 505 to move downward until the locking block 505 is disengaged from the lower end of the locking groove 507 (the guide slide groove 201 overcomes the elastic force of the compression spring 106 and pushes the locking block 505 into the sliding groove 203). At this time, the movement restriction of the guide slider 105 is released, and the two cylinders 405 contract. Under the action, the two cylinders 405 drive the two sliding blocks 1502 to move in the opposite direction, the two sliding blocks 1502 drive the two locking blocks 505 and two opposite guide rods 110 to move in the opposite direction, the two opposite guide rods 110 drive the two L-shaped moving rods 402 to move in the opposite direction, the two L-shaped moving rods 402 drive the other two opposite guide rods 110 to move in the opposite direction through the inclined push groove 403 and the push shaft 404, and then the four guide rods 110 move in the opposite direction synchronously, and the guide rod 110 drives the L-shaped clamping plate 108 to reverse through the connecting rod 111 until the L-shaped clamping plate 108 releases the aluminum alloy extruded profile;Through the cooperation of the locking block 505 and the locking groove 507, the L-shaped clamping plate 108 can be restricted from loosening the aluminum alloy extruded profile when the tooling plate 106 is away from the belt conveyor 102. Only when the tooling plate 106 drives the aluminum alloy extruded profile close to the belt conveyor 102, the L-shaped clamping plate 108 can loosen the aluminum alloy extruded profile, thereby preventing the aluminum alloy extruded profile from falling onto the belt conveyor 102 from a high place, and avoiding damage to the aluminum alloy extruded profile and the belt conveyor 102 due to collision between the aluminum alloy extruded profile and the belt conveyor 102.

The correcting plate 601 drives the correcting protrusion 602 to move toward the aluminum alloy extruded profile. When the four aluminum alloy extruded profiles are respectively attached to the four limiting protrusions 104, the ends of the four aluminum alloy extruded profiles are completely attached. The correcting protrusion 602 cooperates with the limiting protrusion 104 to correct the position of the aluminum alloy extruded profile, thereby reducing the placement accuracy of the aluminum alloy extruded profile, which is convenient for placing the aluminum alloy extruded profile on the tooling plate 106.

After the welding is completed, the motor 2 303 drives the gear 2 302 to rotate, the gear 2 302 drives the gear 1 301 to rotate, the gear 1 301 drives the tooling plate 106 to rotate on the guide slider 105, and the tooling plate 106 drives the four aluminum alloy extruded profiles to flip, so that the other ends of the four aluminum alloy extruded profiles to be welded face upward, and pass through the welding avoidance opening 107 to weld the welding points of two adjacent aluminum alloy extruded profiles. After the welding is completed, the four aluminum alloy extruded profiles are located below the tooling plate 106, and the motor 1 203 drives the wire The rod 202 rotates, and under the guidance of the guide slide groove 201, the rotating screw rod 202 drives the guide slider 105 to move downward through thread transmission, and the guide slider 105 drives the tooling plate 106, the sliding block 1 502, the sliding block 2 504 and the locking block 505 to move downward until the locking block 505 is disengaged from the lower end of the locking groove 507 (the guide slide groove 201 overcomes the elastic force of the compression spring 1 506 and pushes the locking block 505 into the sliding groove 2 503). At this time, the movement restriction of the guide slider 105 is released until the four welded aluminum alloy extruded profiles approach the top of the belt conveyor 102, and the two cylinders 405 contract. Under the guidance of the sliding groove 1 501, the two cylinders 405 drive the two sliding blocks 1 502 to move in the opposite direction.The two sliding blocks 502 drive the two locking blocks 505 and two of the relative guide rods 110 to move in the opposite direction, and the two relative guide rods 110 drive the two L-shaped moving rods 402 to move in the opposite direction, and the two L-shaped moving rods 402 drive the other two relative guide rods 110 to move in the opposite direction through the inclined push groove 403 and the push shaft 404, thereby making the four guide rods 110 move in the opposite direction synchronously, and the guide rod 110 drives the L-shaped clamping plate 108 to reverse through the connecting rod 111 until the L-shaped clamping plate 108 releases the aluminum alloy extruded profile, and the welded aluminum alloy extruded profile falls on the belt conveyor 102, and the belt conveyor 102 drives the welded aluminum alloy extruded profile The material moves away from the tooling plate 106. At this time, the motor 203 drives the screw rod 202 to reverse. Under the guidance of the guide slide 201, the reversed screw rod 202 drives the guide slider 105 to move upward through thread transmission. The guide slider 105 drives the tooling plate 106 to move upward, thereby resetting the tooling plate 106. L-shaped clamps 108 are provided at both ends of the tooling plate 106, so that both ends of the L-shaped clamps 108 can clamp the aluminum alloy extruded profiles, thereby improving the resetting efficiency of the tooling plate 106. The present invention realizes the rapid unloading of the aluminum alloy extruded profiles after welding through the lifting of the tooling plate 106 and the belt conveyor 102, thereby improving the processing efficiency of aluminum alloy doors and windows.
