Cutter run-out on-machine vision detector and detection method thereof

Abstract

The invention relates to a cutter run-out on-machine vision detector and a detection method thereof. The cutter run-out on-machine vision detector comprises a detector, a data processing controller and a cutter data server, the detector is connected with the data processing controller through a signal cable; the data processing controller is further connected with a CNC controller and the cutter data server. A telecentric lens and a backlight source are arranged in the detector; the telecentric lens and the backlight source are used for carrying out parallel projection imaging on the cutter, acutter image sequence is obtained in the rotating process of the cutter, the data processing controller analyzes the cutter image sequence based on the image sequence frame-by-frame dynamic analysisprinciple, and radial run-out and axial run-out of the cutter are automatically detected. By adopting the cutter run-out on-machine vision detector or the detection method thereof provided by the invention, radial and axial run-out of the cutter can be efficiently, accurately and automatically detected at the working rotating speed of the cutter.

Description

technical field [0001] The invention relates to the field of tool runout detection, in particular to an on-machine vision detector for tool runout and a detection method thereof. Background technique [0002] On-machine detection of rotary tools involves five mutually independent functions, namely: tool setting, multi-view detection of micro-tools, tool runout detection, tooth-by-tooth wear detection of front and rear cutter faces, and real-time monitoring of the entire machining process. , the first four functions can only be run before and after machining, and the fifth function can monitor the tool status in the whole process of CNC machining in real time. a specific attribute. This paper only studies the function of tool jump detection. [0003] During the machining process, due to the manufacturing error, assembly error and clamping error of the tool, as well as the assembly error of the spindle, the axis of the tool assembly may not be consistent with the rotation ax...
