A CNC machine tool electric spindle tool holder fixture with digital twin system

Abstract

The invention discloses a CNC machine tool electric spindle tool holder fixture with a digital twin system, including a fixture body, a movable piezoelectric ceramic block, a fixed piezoelectric ceramic block, a detection circuit, a rotary encoder, a data processing module and a digital twin system; the fixture body is provided with a tapered inner hole, and a movable piezoelectric ceramic block is arranged in the concave hole on the front surface of the fixture body, and one end of the movable piezoelectric ceramic block is arranged inside the fixture body through The spring is movably connected to the fixture body, and the protruding end of the movable piezoelectric ceramic block is provided with a conductive touch terminal; it is characterized in that a blind hole is vertically arranged in the tapered inner hole of the fixture body, and a blind hole is arranged in the blind hole Fixed piezoelectric ceramic block, one end of the fixed piezoelectric ceramic block is set inside the fixture body and fixedly connected with the fixture body, the beneficial effect of the present invention is that the change position of the chip detection distance is changed, and the detection accuracy is improved; it can be displayed in real time The specific location of the chips.

Description

technical field [0001] The invention belongs to the technical field of machine tool components, and in particular relates to a CNC machine tool electric spindle tool handle fixture with a digital twin system. Background technique [0002] CNC machine tools are the main machine tools of the equipment manufacturing industry, and their technical level represents the development level of a country's manufacturing industry. The machining center is the first important member of the CNC machine tool. Due to the concentration of processes and automatic tool change in the machining center, the time for clamping, measuring and machine tool adjustment of the workpiece is reduced, so that the cutting time of the machine tool reaches about 80% of the machine tool start-up time (only 15-20% for ordinary machine tools); at the same time It also reduces the workpiece turnover, handling and storage time between processes, shortens the production cycle, and has obvious economic effects.
