[0064] Among them, the outside of the frame 50 is fixedly connected to the side frame 501, and the side frame 501 is fixedly connected to the guide sleeve 90. The jacking assembly also includes an adjusting frame 1004 and a second connecting rod 1005 hinged on both sides of the bottom of the adjusting frame 1004.

The second connecting rod 1005 at the bottom of each adjusting frame 1004 is respectively hinged to the corresponding push rod 901 and the second slider 1007. A second spring 1008 is connected between the adjusting frame 1004 and the base 10. The outside of the slide rod 201 is fixedly connected to the mounting plate 100, and the outside of the mounting plate 100 is provided with a synchronous switching mechanism.

[0065] In this embodiment, the synchronous switching mechanism includes a piston column 1003 fixedly connected to the adjustment frame 1004, a mounting column 1001 fixedly connected to the bottom of the mounting plate 100, and a piston cylinder 1002 fixedly connected to the outside of the mounting column 1001.

[0066] The above technical solution is explained as follows: the first hydraulic cylinder 20 pushes the cross frame 30 to slide downward, the cross frame 30 and the sliding frame move downward synchronously to reduce the distance, the cross plate 102 and the cross frame 30 move downward, which will drive the mounting plate 100 to move downward, the mounting plate 100 drives the mounting column 1001 to move downward, the mounting column 1001 drives the piston cylinder 1002 to move downward, due to the sealing structure of the piston cylinder 1002 and the piston column 1003, the air in the piston cylinder 1002 cannot be discharged (the solenoid valve 10010 is in a closed state), under air pressure, the piston cylinder 1002 pushes the piston column 1003 to move downward synchronously through the air, the piston column 1003 will compress the second connecting rod 1005 through the adjusting frame 1004, the adjusting frame 1004 compresses the second spring 1008, and the second connecting rod 1005 pushes the push rod 901 to slide, and the two push rods 901 respectively push the two second sliding frames 70 to move toward each other;

[0067] In addition, the second sliding frame 70 moves toward each other, thereby driving the first sliding block 801 to move toward each other. The first sliding block 801 contacts the first connecting rod 802, so as to lift the lifting frame 80. The guide column 803 guides the lifting frame 80, stretches the first spring 805, and the lifting frame 80 lifts the web and the wing plate, further allowing the web and the wing plate to approach the laser welding gun 401. At the same time, the two second sliding frames 70 slide toward each other, control the second motor 307 and the third motor 309 to rotate, and further adjust the position of the six-axis robot arm 40. Then, by operating the six-axis robot arm 40, the laser welding gun 401 corresponds to the bottom connection of the web and the wing plate, and welds the two sides of the bottom, as shown in the attached figure. Figure 3 As shown in;

[0068] After completion, the operation is performed to rise and reset, and under the restoring action of the first spring 805 and the second spring 1008, it can be reset to the initial position.

[0069] In addition, if only by lowering the cross frame 30, there will be enough space for the welding gun to weld the bottom connection of the web and the wing plate. When there is no need to lift the web and the wing plate, it is only necessary to open the solenoid valve 10010 to allow the air vent 1009 and the piston cylinder 1002 to maintain ventilation with the outside. In this way, when the cross frame 30 is lowered, the piston cylinder 1002 will slide on the outside of the piston column 1003, and the air will also be discharged through the air vent 1009, thereby not pushing the piston column 1003 and the adjustment frame 1004 to move downward.

[0075] Subsequently, the six-axis robot 40 controls the laser welding gun 401 to weld the contact position of the wing plate and the web, and the first motor 301 and the sixth motor 3010 can also be started to work, thereby driving the first threaded rod 302 and the second threaded rod 304 to rotate, so that the slide frame 303 can move on the cross frame 30, and the nut block 305 moves under the slide frame 303, so that the six-axis robot 40 can be adjusted horizontally and vertically, and the position adjustment of the welding gun is completed, which is convenient for the welding of the wing plate and the web of the welding gun;

[0076] After the welding gun has welded both sides of the top of the connection between the wing plate and the web, the welding of the bottom of the connection between the wing plate and the web is carried out. The specific operation is as follows:

[0077] The fourth hydraulic cylinder 140 is started to pull the first sliding frame 60 to slide, so that the first sliding frame 60 is retracted, and then the first hydraulic cylinder 20 is started to push the cross frame 30 to slide downward, and the cross frame 30 and the sliding frame move downward synchronously to reduce the distance, and when the cross plate 102 and the cross frame 30 move downward, the mounting plate 100 will be driven to move downward, and the mounting plate 100 will drive the mounting column 1001 to move downward, and the mounting column 1001 will drive the piston cylinder 1002 to move downward. Due to the sealing structure of the piston cylinder 1002 and the piston column 1003, The air in the piston cylinder 1002 cannot be discharged (the solenoid valve 10010 is in a closed state). Under air pressure, the piston cylinder 1002 pushes the piston column 1003 to move downward synchronously through the air. The piston column 1003 compresses the second connecting rod 1005 through the adjustment frame 1004. The second connecting rod 1005 pushes the second sliding block 1007 and the push rod 901 to slide respectively. The second connecting rod 1005 pushes the push rod 901 to slide. The two push rods 901 push the two second sliding frames 70 to move toward each other respectively.

[0078] The second sliding frames 70 move toward each other, thereby driving the first sliding blocks 801 to move toward each other. The first sliding blocks 801 abut against the first connecting rods 802, so as to lift up the lifting frame 80. The guide columns 803 guide the lifting frame 80. The lifting frame 80 lifts up the web and the wing plate, further allowing the web and the wing plate to approach the laser welding gun 401. At the same time, the two second sliding frames 70 slide toward each other to reduce the occupied space.

[0079] Then, the second motor 307 and the third motor 309 are controlled to rotate, and the position of the six-axis robot arm 40 is further adjusted. Then, by operating the six-axis robot arm 40, the laser welding gun 401 is made to correspond to the bottom connection of the web and the wing plate, and the two sides of the bottom are welded. Figure 3 As shown in;

[0080] In addition, if only by lowering the cross frame 30, there will be enough space for the welding gun to weld the bottom connection of the web and the wing plate. When there is no need to lift the web and the wing plate, it is only necessary to open the solenoid valve 10010 to allow the air vent 1009 and the piston cylinder 1002 to maintain ventilation with the outside. In this way, when the cross frame 30 is lowered, the piston cylinder 1002 will slide on the outside of the piston column 1003, and the air will also be discharged through the air vent 1009, thereby not pushing the piston column 1003 and the adjustment frame 1004 to move downward.

[0081] Embodiment 2

[0082] Reference Fig. 9 The difference between this embodiment and the first embodiment is that in this embodiment, the second electromagnet 120 is fixedly connected to the bottom of the mounting column 1001 and the top of the piston column 1003, and the first electromagnet 110 is fixedly connected to the outside of the vertical rod 101.

[0083] The above technical solution is explained as follows: if the piston cylinder 1002 is not used, the second electromagnet 120 is directly used to achieve the corresponding function, and the two second electromagnets 120 are arranged with the same poles repelling each other;

[0084] When the slide bar 201 moves downward, it will drive the mounting column 1001 to move downward. At this time, the two second electromagnets 120 with the same poles repel each other, and the adjustment frame 1004 can be pushed downward by the repulsive force.

[0085] If only the slide bar 201 and the horizontal frame 30 need to move downward, the two second electromagnets 120 only need to be powered off to lose their magnetism, so that when the slide bar 201 slides downward, the adjustment frame 1004 will not be driven to move downward;

[0086] The first electromagnet 110 is used to adsorb and fix the adjustment frame 1004 in the initial state, thereby ensuring the stability of the second sliding frame 70, and the adjustment frame 1004 is made of iron material.

[0087] Embodiment 3

[0088] Reference Fig.10 -Attached Fig.11 The difference between this embodiment and the first embodiment is that, in this embodiment, a dual-axis cylinder 130 is fixedly connected to the bottom of the frame 50, and the output end of the dual-axis cylinder 130 is fixedly connected to the second fixed plate 1301, the external rotation of the second fixed plate 1301 is connected to the first gear 1303 and the second gear 1304, the external part of the second gear 1304 is fixedly connected to the correction plate 1305, the external part of the second fixed plate 1301 is fixedly connected to the fifth motor 1302, and the output end of the fifth motor 1302 is fixedly connected to the first gear 1303.

[0089] The above technical solution is explained as follows: when the web is conveyed to the conveying roller 701, there may be an offset. The web is a steel plate with a heavy weight and cannot be adjusted quickly by manual operation. It is only necessary to start the double-axis cylinder 130 to extend it, start the fifth motor 1302 to drive the first gear 1303 to rotate, the first gear 1303 drives the second gear 1304 to rotate, and the second gear 1304 drives the correction plate 1305 to rotate, so that the correction rotates a certain angle to correspond to the side wall of the web, and then control the double-axis cylinder 130 to retract, so that the web can be balanced on the second sliding frame 70 through the interference of the correction plate 1305, so as to facilitate the subsequent fitting of the wing plate. After completion, the fifth motor 1302 is controlled to rotate and the double-axis cylinder 130 is controlled to work again, so that the correction plate 1305 can be retracted to the bottom of the frame 50.
