Abstract

The invention discloses a clamp system and a machining method for high-speed precision broaching machining of a turbine disc mortise. The clamp system comprises a pressure sensor, a vibration acceleration sensor, signal collecting and processing equipment and a clamp for clamping a workpiece. The clamp comprises a clamp body, a pressing plate, an upper plate and pressing bolts, the pressure sensorand the vibration acceleration sensor are electrically connected with the signal collecting and processing equipment, and the pressing plate and the upper plate are connected to form a space containing the workpiece through the pressing bolts. The upper plate is arranged on the clamp body, the pressure sensor is arranged in the clamp body, and the vibration acceleration sensor is arranged in theupper plate. The clamp system can monitor the machining state such as tool abrasion, abnormal vibration, cutting force and other parameters in real time, through the method, the machining strategy canbe adjusted through monitoring of the tool state, and optimal machining of the turbine disc mortise is achieved.

Description

technical field [0001] The invention belongs to the technical field of plate forming, in particular to a fixture system and a processing method for high-speed precision broaching and machining of a tenon and groove of a turbine disk. Background technique [0002] As a key component of a gas turbine, the turbine disk is connected to the blade through a tenon and groove. In the case of heavy-duty high-power transmission, the connection accuracy of the tenon and groove at the connection between the turbine disk and the blade is crucial to its connection reliability. The material of the turbine disk is usually a nickel-based alloy. During the machining process, the tool is easy to wear and flutter, which seriously affects the machining efficiency and machining accuracy. In order to solve the above problems, the present invention provides a fixture system capable of real-time monitoring of machining status, such as tool wear, abnormal vibration, cutting force and other parameters...
