Abstract

A device for measuring end face deformation of a face milling tool based on a double-pulse laser, consisting of a spindle box, an electric spindle, a connecting tool bar, a fixed platform, a base, a controller, a double-pulse laser, a set bolt, a laser emitting end, a CCD lens, The face milling cutter head, milling cutter, milling workpiece, clamping device, and ball screw are composed; the spindle box is connected with the base, the electric spindle and the controller are fixed on the upper end of the spindle box, the electric spindle is equipped with a connecting tool bar, and the double pulse laser passes through The set bolt is fixed on the connecting tool bar, the laser emitter and CCD lens are installed on the double pulse laser, the face milling cutter disc is installed on the connecting tool bar, the milling cutter is on the face milling cutter disc, and the milling cutter is clamped on the clamping device. For the workpiece, the fixed platform is installed at the lower end of the headstock, on which there is a clamping device and a ball screw. The measuring device installs a miniaturized measuring system on the high-speed rotating connecting tool rod, so that the high-speed dynamic measurement is transformed into a quasi-static measurement. Non-contact, high precision, strong vibration resistance and other advantages.

Description

technical field [0001] The invention relates to a face milling tool end face deformation measuring device based on a double pulse laser, specifically, a face milling tool composed of a spindle box, an electric spindle, a double pulse laser, a face milling cutter disc, etc. end-face deformation measuring device. Background technique [0002] High-speed cutting technology is becoming the mainstream of cutting processing. In the process of high-speed cutting, tool stress distribution directly affects the reliability and cutting performance of the tool. When cutting at high speed, the main form of tool damage of face milling cutter is breakage. The main cause of tool damage is the result of various stresses such as mechanical stress and thermal stress. Under different cutting conditions, mechanical stress and thermal stress are mutually dominant to cause damage to cutting tools. Due to the limitation of measurement methods and measuring instruments, there are few researches on...
