Beneficial effects

[0008] 1. This utility model fixes both ends of a fixed mounting plate to both ends of a U-shaped support platform. A cylinder is fixed to the fixed mounting plate. A rectangular anti-detachment block is connected to the slide plate through a strip-shaped sliding hole. The rectangular anti-detachment block prevents the horizontal slide plate from moving laterally during machining, ensuring only vertical movement. When the cylinder operates, the piston rod drives the horizontal slide plate to slide up and down. A fixed connecting plate is installed and fixed to the upper part of the U-shaped support platform. The upper part of the fixed connecting plate is connected to a rotating pressure plate via a No. 3 rotating shaft. This allows the fixed connecting plate to provide fixed support for the rotating pressure plate while the rotating pressure plate can rotate around the No. 3 rotating shaft. The lower part of the rotating connecting rod is connected to symmetrical lower connecting ears via a lower rotating shaft, connecting the lower part of the rotating connecting rod to the horizontal slide plate. As the horizontal slide plate slides up and down, it drives the rotating connecting rod to move up and down simultaneously, allowing the rotating connecting rod to rotate.

[0009] 2. In this utility model, the upper part of the rotating connecting rod is connected to symmetrical upper connecting ears via an upper rotating shaft, so that the upper part of the rotating connecting rod is connected to the tail end shaft of the rotating pressure plate. When the horizontal sliding plate moves upward, it drives the rotating connecting rod to push the tail end of the rotating pressure plate, causing the rotating pressure plate to rotate around the No. 3 rotating shaft. This causes the clamping protrusion to clamp the automotive parts to be processed. The symmetrical rotating pressure plates clamp the two sides of the automotive parts to be processed at both ends, fixing the automotive parts to be processed on the U-shaped support platform, which facilitates the cutting tool to process the inner hole of the automotive parts to be processed. When using this device, it can clamp automotive parts of different thicknesses and can be used for processing, clamping and positioning automotive parts within a certain thickness range.
