Abstract
The utility model discloses a workpiece centering and clamping mechanism of a numerical controlled cam milling machine. The workpiece centering and clamping mechanism comprises a hydraulic chuck which is fixedly arranged on a machine body and is used for clamping a workpiece, wherein a centering tip I used for pre-tightening a machined section of the workpiece and a centering tip II used for pre-tightening a non-machined section of the workpiece are arranged at two ends of the hydraulic chuck respectively. The centering tip I is arranged on the machine body in a mode of being capable of moving in the axial direction of the workpiece. According to the workpiece centering and clamping mechanism of the numerical controlled cam milling machine, due to the fact that the centering tip I and the centering tip II which are coaxial abut against center holes in the two ends of the workpiece, so that the center line of the workpiece and the machining and locating center line are consistent, a machining and locating standard and a detection standard are consistent, machining errors and detection errors caused by clamping and locating can be avoided, the product quality and the product qualified rate are effectively improved, and economic benefits are increased. After the hydraulic chuck clamps the workpiece, the centering tip I releases the workpiece and does not affect machining on the workpiece, the centering tip II can continuously abut against the workpiece, and the workpiece centering and clamping mechanism is beneficial for keeping the workpiece stable in the machining process.
