[0034] The working principle and use process of the utility model: when in use, the device is fixed to the ground through the chassis 2, and the column 1 is vertically fixed on the chassis 2 to form a stable support structure. When a large frame needs to be handled, the frame is placed on the bracket 13 on the top of the main support rod 9 and the auxiliary support rod 10, and the frame is positioned and fixed using the hanging buckle 14 on the top of the bracket 13. The auxiliary support rod 10 is fixedly connected to the main support rod 9 through the pin 12 and the positioning hole 11 to ensure the stability of the entire support structure. When the length or width of the frame is large, the operator can turn the knob 7 at the bottom of the chassis 2 and rotate it with the tool through the slot 8. The knob 7 drives the screw 5 to rotate, thereby causing the lifting rod 3 to move up and down inside the column 1 to adjust the height to adapt to different sizes. The frame, at the same time, the bracket 13 is fixedly connected to the slide groove 15 by the hand-tightened bolts 16, and can slide above the main support rod 9 and the auxiliary support rod 10 to adjust the gap between the frames to avoid the lower end fixing mechanism blocking the shot blasting of the upper end frame to ensure uniform rust removal effect. After the frame is fixed, the shot blasting machine starts to work, and high-speed hard projectiles are used to impact and clean the surface of the frame. Since the main components such as the column 1, the chassis 2, and the lifting rod 3 are made of high manganese steel, they have high wear resistance and strength and can withstand the strong impact generated during the shot blasting process. Through this highly adjustable and stable fixing method, the large-scale frame shot blasting fixing device effectively improves the effect of frame shot blasting and rust removal, improves the appearance quality of the frame, and also improves production efficiency.
