[0041] Working principle: Before using the anti-deviation vehicle anti-collision beam welding device, the overall situation of the device needs to be checked to determine whether it can work normally, according to Figure 1 - Figure 8 When different types of anti-collision beams are replaced and the height size of the anti-collision beam changes greatly, first, press the pressing plate 215 to make it rotate, so that the clamping hook 216 rotates outward and is separated from the clamping inclined block 219, so that the spring 213 pushes the two protruding blocks 211 to separate, and then the two half-threaded sleeves 208 slide on the central lifting plate 203 and separate, so that the central lifting plate 203 can directly move vertically with the rotating lifting plate 204, thereby quickly adjusting the distance between the pressing plate 206 and the bottom of the central clamping frame 201, avoiding the situation that when the position of the screw sleeve is greatly adjusted by directly rotating the screw column 207, the screw column 207 needs to be constantly rotated, which is time-consuming and laborious, and at the same time, the cost of the equipment for configuring an electric clamping auxiliary clamping for the central clamping frame 201 and the side clamping frame 202 is reduced, and finally the two half-threaded sleeves 208 are re-clamped and spliced, and are threadedly connected with the screw column 207, the anti-collision beam is placed below the pressing plate 206, and then the screw column 207 is rotated to press the anti-collision beam tightly, so that the disassembly efficiency of the anti-collision beam is not greatly reduced without the use of electrical equipment to assist in fixing the anti-collision beam.

[0042] When the anti-collision beam needs to be disassembled, only the pressing plate 215 needs to be pressed to separate the two half-threaded sleeves 208 again, so that the anti-collision beam is no longer firmly extruded, and then it can be quickly disassembled.

[0043] When the curvature of the two sides of the crash beam changes greatly, the area of the pressing plate 206 contacting the crash beam is reduced, at this time the rotating bolt 304 makes the clamping block 305 disengage from the inner ring gear 302, at this time the rotating column 301 can rotate freely, so that the rotating lifting plate 204 and the side clamping frame 202 can slide on the curved groove 306 together, and then the position of the pressing plate 206 can be changed according to the shape of the crash beam, finally the crash beam can be stably fixed, avoiding the situation that the crash beam shakes due to insufficient extrusion force during processing, and then causing the welding point to deviate.

[0044] When the maximum length of different crash beams changes, by replacing the blocking plate 402 with different thicknesses and inserting it with the vertical groove 401, the two sides of the crash beam can be in contact with the blocking plate 402, as long as it is ensured that the two sides of the crash beam are in contact with the blocking plate 402 during installation, and the back of the crash beam is in contact with the vertical surface of the center clamping frame 201, it can be ensured that the crash beam is installed horizontally each time, and the crash beam is prevented from deviating during installation.
