The invention relates to an on-machine vision detector for tool runout and a detection method thereof. The on-machine vision detector for tool jumping includes: a detector, a data processing controller and a tool data server; the detector and the data processing controller are connected by a signal cable; the data processing controller is also connected to the CNC controller and the tool respectively The data server is connected; the detector is equipped with a telecentric lens and a backlight light source, and uses the telecentric lens and the backlight light source to perform parallel projection imaging on the tool, and acquires a tool image sequence during the tool rotation process. The data processing controller is based on The principle of frame-by-frame dynamic analysis of the image sequence analyzes the tool image sequence to automatically detect the radial runout and axial runout of the tool. The tool runout on-machine vision detector or its detection method provided by the invention can efficiently and accurately detect the radial runout and axial runout of the tool at the working speed of the tool.
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...
