The frame workpiece is lifted from the workpiece conveying line 1 by the lifting component 4, and the centering component 5 clamps the frame workpiece to center it.

[0019] As a further illustration, Figure 2 As shown, the lifting assembly 4 includes a base 401 and a mounting platform 402 for carrying the centering mechanism 5, one end of the base 401 and the mounting platform 402 is installed with four groups of hinges 403, and the other end is installed with four groups of slide rails 404, the four groups of slide rails 404 are installed with sliders 405, the sliders 405 are hinged with lifting cylinders 406, and the four groups of hinges 403 are connected with push rods 407; the end of the push rod 407 located on the hinge 403 of the base 401 is hinged to the slider 405 on the mounting platform 402, and the end of the push rod 407 located on the hinge 403 of the mounting platform 402 is hinged to the slider 405 on the base 401, and the midpoints of two adjacent push rods 407 are connected by axes to form two groups of X-shaped brackets; the lifting cylinder 406 is telescopic to drive the slider 405 to slide, so that the distance between the end points of the two groups of X-shaped brackets is reduced, driving the mounting platform 402 to rise and fall.

[0020] like Figure 3 As shown, the centering component 5 includes a connecting rod 501 connected to the axis at the center of the mounting platform 402, and two sets of swing arms 502 are hinged at both ends of the connecting rod 501. The ends of the two sets of swing arms 502 are respectively connected to two sets of centering baffles 503 that are symmetrical on the left and right. The two sets of centering baffles 503 are connected to the mounting platform 402 for opposite sliding. One of the two sets of centering baffles 503 is connected to a centering cylinder 504 that drives the sliding.

[0021] like Figure 4 As shown, the correction device 3 consists of a frame body 6, an oblique support frame 7 slidably connected to the frame body 6, two sets of mirror-image correction components 8 are slidably installed on the oblique support frame 7, and the oblique support frame 7 is driven by a driving component 9 to move toward the jacking and centering device 2, and the correction component 8 corrects the part of the frame workpiece that needs to be corrected.

[0022] like Figure 5 As shown, the driving assembly 9 includes a screw 901 connected to the frame body 6 by a bearing, the screw 901 is rotated by a motor 902, and the oblique support frame 7 is threadedly connected to the screw 901 on the frame body 6 for linear motion.

[0023] The correction assembly 8 includes a correction block 801 installed on the side of the inclined support frame 7 facing the jacking and centering device 2. The correction block 801 has a correction cavity 803 on the side facing the jacking and centering device 2. The correction block 801 is connected to the output shaft of the correction cylinder 802 and is driven by the correction cylinder 802 to slide linearly on the inclined support frame 7.

[0024] A wear-resistant block 804 is installed near the outer edge of the correction cavity 803. The wear-resistant block 804 is symmetrically arranged near the outer edge of the correction cavity 803.

[0025] As a further limitation, the correction cylinder 802 is mounted on the oblique support frame 7 via an angle seat 805 .

[0026] When using this type of frame correction tooling, first, the frame workpiece is transported through the workpiece conveyor line 1. When it is transported to the jacking and centering device 2, the jacking component 4 is started, and the jacking cylinder 406 retracts to drive the slider 405 to slide on the slide rail 404. The two groups of X-shaped brackets connected to the slider 405 and the hinge 403 change the end point spacing to raise the mounting table 402 to lift the frame workpiece, and the centering component 5 is started. The centering cylinder 504 drives one side of the centering baffle 503 to slide on the mounting table 402. Since the two groups of centering baffles 503 are connected to the connecting rod 501 in the middle of the mounting table 402 through the swing arm 502, when the centering baffle 503 on one side slides, the centering baffle 503 on the other side is synchronously pulled to center the frame workpiece.

After adjusting the alignment, the driving component 9 is started, and the motor 902 drives the screw 901 to rotate and threadedly connect the oblique support frame 7 on the frame body 6 to slide toward the frame workpiece and approach the frame workpiece until the correction part on the frame workpiece is located in the correction cavity. The oblique support frame 7 is equipped with a distance sensor 10. When the distance between the distance sensor 10 and the part to be corrected by the frame workpiece is greater than or less than the preset value, the pressure of the correction cylinder 802 is adjusted at this time, and the correction is performed through the correction block 801, and the part to be corrected is deformed with the assistance of the lifting and centering device 2, until the distance sensor 10 detects that the distance between the parts to be corrected of the workpiece is within the preset value range, and the correction cylinder 802 stops running, and the correction is completed.
