The invention discloses a clamp device for an automobile ABS brake valve, comprising a bottom plate. The bottom end of the bottom plate is provided with a rotating support mechanism, a placing block is fixedly connected to the side wall of the upper end of the bottom plate, a first placing groove is formed in the side wall of the upper end of the placing block, a second placing groove is formed inthe inner wall of the first placing groove, a clamping mechanism is arranged on the placing block, a cylinder is fixedly connected to the side wall of the upper end of the bottom plate, the output end of the cylinder is fixedly connected to a first concave block, and a pressing mechanism is disposed above the placing block. The clamp device for an automobile ABS brake valve has the advantages ofsimple structure, simple operation, time and labor saving, not only clamping the brake valve from the side direction, but also clamping the brake valve from top to bottom, so that the clamping and fixing of the brake valve is more stable. By using the clamp device, the brake valve can be rotated and processed at different angles according to different requirements, thereby improving the processingefficiency of the brake valve.
