Abstract
The utility model discloses a quick positioning four-axis clamp for steering knuckle machining. The quick positioning four-axis clamp comprises a bridge plate. A cushion block is installed below the bridge plate, a speed regulation valve seat is installed above the bridge plate, an oil inlet speed regulation valve is installed on the speed regulation valve seat, and a positioning structure, a pressing structure and a locking structure are installed above the bridge plate. During use, a steering knuckle blank is placed on the profiling positioning block, the profiling positioning block is attached to the end face of a steering knuckle supporting arm, the three first lever pressing plates penetrate through a center hole of a blank piece, meanwhile, the rhombic pin is embedded into a groove hole of the steering knuckle blank piece, coarse positioning of the blank piece is achieved, then the first lever cylinder, the second lever cylinder and the corner cylinder are started at the same time, and the steering knuckle blank piece is positioned. The first lever pressing plate, the second lever pressing plate, the first corner pressing plate and the second corner pressing plate can be driven to press the surface of the steering knuckle blank, rapid positioning and locking of the steering knuckle blank are achieved, frequent manual locking operation is not needed, and the repeated positioning precision is improved.
