[0004] This utility model discloses a clamping device for bridge railing production, comprising a base, two upright plates, a position adjustment component, a support component, and a clamping component. The bottom of the two upright plates is mounted on the left and right sides of the top of the base via the position adjustment component. The support component is mounted on the top of the upright plates, and the clamping component is mounted on the support component. According to the processing requirements, the position of the upright plates on the top of the base is adjusted by the position adjustment component. The two ends of the horizontal tube are placed on the support component on the top of the upright plates, and then the clamping component fixes the horizontal tube. The operation is simple and helps to improve processing efficiency.

[0005] Preferably, the position adjustment component includes two threaded rods, two rotating wheels, two adjusting sliders, and two movable seats. Position adjustment slots are provided on the left and right sides of the top of the base. The threaded rods are rotatably installed in the position adjustment slots, and rotating wheels are installed at the input end of the threaded rods. The adjusting sliders are slidably installed in the position adjustment slots and screwed onto the outer wall of the threaded rods. Movable seats are installed on the top of the adjusting sliders, and the bottom of the upright plate is connected to the top of the movable seats. The rotating wheels drive the threaded rods to rotate, causing the adjusting sliders to move within the position adjustment slots, thereby causing the movable seats to move the upright plate on the top of the base. This allows for adjustment of the support position of the upright plate according to actual processing requirements, improving practicality.

[0006] Preferably, the support components include two rotating seats, two rotating shafts, two support frames, and two support seats. The support frames are located at the top of the upright plate, and the rotating seats are installed at the bottom of the support frames. The rotating seats are rotatably installed at the top of the upright plate via the rotating shafts, and the support seats are installed at the middle of the top of the support frames. The horizontal tube is placed on the support frame at the top of the upright plate, and the bottom of the horizontal tube is supported by the support seats.
