Moreover, the first fine adjustment screw rod 4 horizontally threadedly penetrates through the upper end of the support frame 203, and the structure between the second fine adjustment screw rod 8 and the first fine adjustment screw rod 4 is the same. The first clamping plate 3 includes a clamping plate main body 301, an anti-slip plate 302, a connecting seat 303 and a guide slider 304. The anti-slip plate 302 is attached to the surface of the clamping plate main body 301 on the side close to the vertical central axis of the clamping table 2, and a connecting seat 303 is arranged at the upper end of the clamping plate main body 301 away from the anti-slip plate 302.

The adjustment frame 5 includes a stable seat 501, a bearing seat 502, a third fine adjustment screw rod 503 and a guide post 504. The bearing seat 502 is connected to the side of the stable seat 501 away from the track frame 7, and the third fine adjustment screw rod 503 is vertically installed on the top of the bearing seat 502.

[0025] In summary, as Figures 1 to 4 shown in the figure, when using this adjustable clamping structure, first, according to the usage requirements, the entire device is fixed to the operation table or the device structure surface by using the first angle plates 102 and the second angle plates 103 on both the left and right sides and the front and back sides of the pedestal 101 in cooperation with the use of bolts;

[0026] Then, according to the clamping requirements of the automotive parts, start the electromagnetic adsorption table 201 at the top of the base assembly 1 to electromagnetically adsorb the automotive parts. At the same time, according to the structure of the parts, rotate the third fine adjustment screw rod 503 installed in the middle of the bearing seat 502 in the vertical direction, so that the movable frame 6 threadedly connected to the third fine adjustment screw rod 503 by the second threaded sleeve 605 will respectively use the auxiliary sliders 603 and the sliding sleeves 604 on both sides of the movable pile 601 to move vertically along the surfaces of the track frame 7 and the guide post 504;

[0027] After adjustment, at this time, only the first fine-tuning lead screw 4 inside the upper end of the support frame 203 and the second fine-tuning lead screw 8 inside the first threaded sleeve 602 need to be screwed in sequence horizontally, so that the connected first clamping plate 3 and the second clamping block 9 are horizontally pushed toward the side surface of the automotive part respectively. During the movement of the first clamping plate 3, the clamping plate main body 301 moves with the rotation of the lead screw main body 401 under the connection combination of the connecting seat 303 and the connecting frame 403. At the same time, the guiding slider 304 at the bottom of the clamping plate main body 301 will slide along the surface of the guide rail 202 until the anti-slip plate 302 closely adheres to the side surface of the automotive part, thereby completing the clamping operation.
