The aluminum cylinder needs to be subjected to a series of processing such as cold bending and painting during production, and a clamp is needed to fix the aluminum cylinder.

[0003] For example, a motorcycle shock absorber drilling machine fixture with publication number CN214237268U includes a base, a hanger and a drilling machine; a fixing cylinder is provided on the top wall of the hanger, a first arc-shaped clamping block is provided in the fixing cylinder, a first compression spring is provided on the top of the first arc-shaped clamping block, a support plate is provided below the first arc-shaped clamping block, and a second arc-shaped clamping block is provided on the top of the support plate; a concave block is provided at the bottom of the support plate, and a hydraulic cylinder is provided below the concave block; a connecting rod is provided at the bottom of the support plate, a slider is provided at one end of the connecting rod, the slider is penetrated on the slide rod, a second compression spring is provided between the slider and the hanger, a touch rod is fixed on one side of the slider, and a control switch is provided on the hanger. After placing the aluminum tube on the second arc-shaped clamping block, you can release your hands, the support plate will automatically move down, driving the connecting rod to rotate downward, and when the touch rod touches the control switch, the hydraulic cylinder pushes the support plate upward, so that the aluminum tube presses against the first arc-shaped clamping block, completing the stable clamping of the aluminum tube and preventing it from arching upward. The structure is simple and the degree of automation is high. However, the device clamps the aluminum tube up and down through the first arc-shaped clamping block and the second arc-shaped clamping block, and the inside of the aluminum tube lacks support.
