Abstract

The invention discloses a fixture system and a processing method for high-speed precision broaching and machining of a tenon and groove of a turbine disc. The fixture system includes a pressure sensor, a vibration acceleration sensor, signal acquisition and processing equipment, and a fixture for clamping a workpiece. The fixture includes The main body of the fixture, the pressure plate, the upper plate and the compression bolts, the pressure sensor and the vibration acceleration sensor are all electrically connected to the signal acquisition and processing equipment, the pressure plate and the upper plate are connected by the compression bolts to form a space for accommodating the workpiece, and the upper plate is installed on the main body of the fixture On the top, the pressure sensor is built in the main body of the fixture, and the vibration acceleration sensor is built in the upper plate. The invention can monitor the processing state in real time, such as tool wear, abnormal vibration, cutting force and other parameters of the fixture system, and adjust the method of processing strategy according to the state of the monitoring tool, so as to realize the optimal processing of the tenon and groove of the turbine disk.

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 disc. 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...
