In this way, under the action of the adjustment of the connecting rod 403, the hinge rod 404 and the hinge base 405 interact with each other, allowing the hinge base 405 to adjust the rotating table 406 to a suitable position under the transmission adjustment.

[0042] A hinge connection is provided on the top side of the rotating platform 406, and a second cylinder 408 is provided on the outside of the fixed base 407, an adjustment block 409 is provided at one end of the second cylinder 408, an electric rotating seat 4010 is provided on the outside of the adjustment block 409, and a pneumatic telescopic arm 4011 is provided on one side of the electric rotating seat 4010.

[0043] In an embodiment of the present invention, when the rotating table 406 is adjusted to a suitable position, the second cylinder 408 on the outside of the fixed base 407 is started to output power to drive the output end of the second cylinder 408 to adjust to a suitable length. After the output end of the second cylinder 408 is adjusted to a suitable position, under the action of the electric rotating seat 4010 provided on the outside of the adjustment block 409, two sets of different pneumatic telescopic arms 4011 are allowed to run to their respective angles suitable for clamping the automobile end plate under the adjustment of the electric rotating seat 4010 according to the specific structure of the automobile end plate.

[0046] The working principle of the present invention is: first, by placing the base 101 at the processing location, the bolt steel frame 102 is connected to the top side of the base 101 by bolts for support, and the inner bottom net 104 is bolted to the bolt steel frame 102 through the special-shaped connecting plate 103. Since the inner bottom net 104 is a grid-like structure, it can effectively cushion the workpiece that accidentally falls. Then, the upper support platform 105 is bolted to the top side of the bolt steel frame 102, and the user is allowed to bolt the limiting rod 107 above the two ends of the upper support platform 105 through the side bracket 106. Since the limiting rod 107 is arranged above both sides of the upper support platform 105, the workpiece carried by the low-position adjustment mechanism 2 is limited, and the adjustment angle of the low-position adjustment mechanism 2 is too large. When it is necessary to adjust When the automobile end plate is clamped and fixed, the driving screw rod 3010 on the screw arm 309 outputs power according to the size of the automobile end plate, so that the driving screw rod 3010 drives the slider 3011 to move to a suitable position under rotation. When the slider 3011 moves to a suitable position, the first cylinder 402 on one side of the outer connecting frame 401 is started to output power to drive the connecting rod 403 at one end of the output end of the first cylinder 402 to adjust the length. In this way, under the action of the adjustment of the connecting rod 403, the articulated rod 404 and the articulated base 405 interact with each other, so that the articulated base 405 adjusts the rotating table 406 to a suitable position under transmission adjustment. When the rotating table 406 is adjusted to a suitable position, the second air cylinder 402 on the outside of the fixed base 407 is started. The cylinder 408 outputs power to drive the output end of the second cylinder 408 to adjust to a suitable length. After the output end of the second cylinder 408 is adjusted to a suitable position, under the action of the electric rotating seat 4010 provided on the outside of the adjustment block 409, the two sets of different pneumatic telescopic arms 4011 are adjusted to respective angles suitable for clamping the end plate of the automobile under the adjustment of the electric rotating seat 4010 according to the specific structure of the automobile end plate. Then, when the electric rotating seat 4010 runs to a suitable clamping angle, the hinge base 4013 at the inner end of the end connecting block 4012 is adjusted so that the pneumatic telescopic strip 4014 on the inner side of the hinge base 4013 is adjusted to a suitable clamping angle, and the pneumatic telescopic strip 4014 is started to output power, so that the pneumatic telescopic strip 4014 and the hinge base 4013 are adjusted to a suitable clamping angle. Under the cooperation with each other, the clamping strips 4015 at both ends of the pneumatic telescopic strip 4014 clamp the automobile end plate inward, and the clamping strips 4015 and the magnetic patch 4016 clamp the automobile end plate. After the adjustment clamping mechanism 4 arranged on the outer sides of the two ends of the fine-tuning swivel component 3 clamps the automobile end plate, the welding operation is carried out, and the lower clamping sleeve 305 is plugged in above the two ends of the side connecting seat 303 through the plug-in rod 304, so that the top side of the lower clamping sleeve 305 is plugged into the upper arc-shaped clamping sleeve 306, and the third motor 307 outputs power to drive the screw arms 309 arranged on both sides of the rotating table 308 to limit the rotation range when rotating. After the fine-tuning swivel component 3 and the adjustment clamping mechanism 4 clamp the automobile end plate, when welding, when it is necessary to adjust the appropriate welding angle,The first motor 201 is started to output power to drive the first gearbox 202 to change speed. Through the speed change of the first gearbox 202, the angle of the first side plate 204 driven by the output end of the first output shaft 203 is adjusted. Then, the second motor 206 is started to output power to drive the second output shaft 207 to rotate. After the second output shaft 207 rotates, it drives the inner base 208 to adjust to a suitable angle. Then, according to the welding height, the hydraulic cylinder 209 installed on the inner base 208 is used to output power to drive the output end of the hydraulic cylinder 209 to operate. The output end of the hydraulic cylinder 209 drives the lifting frame 2010 to adjust the height. The lifting platform 2011 installed on the top side of the lifting frame 2010 is adjusted in height according to the specific welding height, so that the equipment can meet the welding operation requirements.
