On-machine quality detecting system for complex space type surface

Abstract

The invention discloses a complex space surface on-machine quality test system, comprising a processing center, three coordinate probes and a measuring signal receiver. The processing center is used to process parts and is equipped with an open numerical control system. The probes are controlled by the numerical control system of a numerically controlled machine tool, and are used to obtain the geometrical measurement value of the discrete points on the surface of the workpiece which has been processed. The measuring signal receiver is used to receive the infrared signals sent by the probes, and transmits the signals to the numerical control system. The numerical control system transmits the measurement value signals to the computer of the user through a communication system, and controls the main shaft of the numerically controlled machine tool to stop moving at the same time. The computer of the user which is provided with a measurement control and error evaluation module is used to exchange data with the numerical control system through the communication system, and evaluates the error and gives an evaluation result based on the ideal value and measurement value of measuring points through the measurement control and error evaluation module. The complex space surface on-machine quality test system can inspect the quality of the workpiece at any moment during processing, guarantees the processing precision of the workpiece, and saves time.

Description

technical field [0001] The invention relates to a processing quality inspection system for workpieces in a machining center, in particular to an on-machine inspection system that runs on a machining center and uses a high-precision measuring head to automatically detect the quality of workpieces with complex spatial profiles. Background technique [0002] In the process of CNC machining, the traditional method of measuring workpieces uses various conventional measuring tools (dial gauges, calipers, etc.) or equipment (three-coordinate measuring machines, etc.). For simple geometric measurement, the operator can directly use the measuring tool on the CNC machine tool to measure; for more complex measurement problems such as the geometric characteristics or spatial position of the workpiece, the operator must transfer the workpiece to three-coordinate measurement because the conventional measuring tool cannot solve it. On board. As a precision measuring equipment, three-coord...
