Problems solved by technology

[0002] In high-speed cutting CNC machining, in order to improve the precision of the workpiece and control the shape and texture, it is particularly important to consider the cutting force modeling of the tool jump and the shape and texture algorithm. Most of them need to detect the tool before machining, so that the geometric accuracy of the tool To meet the accuracy of the parts to be processed, the existing method of detecting tool accuracy is a static detection method, that is, to install a rotary tool such as a milling cutter on the spindle, which generally measures the machine tool that is stopped by a measuring instrument, and does not consider the CNC machine tool. The tool used in the machining process and the tool replaced from the spindle are inspected. If high-precision machining is required, the measurement data of the tool on the spindle in high-precision machining cannot be obtained in real time.

Abstract

The invention relates to the technical field of tool performance testing, in particular to a device and method for detecting tool jumping on equipment. The device and method are characterized in thata rotary frame is arranged on a main shaft in a sliding way; and the rotary frame moves towards a tool along the main shaft for driving a laser displacement sensor to detect the tool handle jumping amount and the blade jumping amount of the tool. The tool jumping amount and the blade initial angle can be acquired by calculation, the tool replaced from the main shaft in the machining process of a numerical control machine tool can be detected in real time; the machining quality of high-precision machining is ensured; and the measured data result is reliable. The device and method are convenientto operate, and high in automation degree.
