Problems solved by technology

When the shaft core is installed on the machine body, generally, there are high-speed bearings using non-metallic materials. The ceramic balls of the ceramic ball bearing itself are non-conductive materials, so it is difficult to use the ceramic ball bearing as a part of conducting electrical signals. , In addition, if the body shell conducts electrical signals, there will be interference and unsafe factors

Abstract

The invention discloses an electric spindle with a conductive structure of a cutting machining monitoring system. The electric spindle comprises a body, the intelligent monitoring system, a central spindle, a cutter, a slip ring and a carbon rod. A positive wiring terminal of the intelligent monitoring system is electrically conducted with the carbon rod, and the slip ring and the carbon rod are in contact with each other, can be in running fit with each other and are electrically conducted with each other; the intelligent monitoring system is electrically conducted with the carbon rod via an external machined workpiece, the central spindle, a draw bar on the central spindle and the slip ring; a monitoring electric signal conduction circuit can be formed. Owing to the mode, the electric spindle has the advantages that machining electric signal transmission circuits are reasonable, external interference on electric signals can be prevented, and the electric signals can be smoothly conducted to the cutter and the spindle which rotates at high speeds; the electric spindle which runs at the high speeds can be used as an electric information transmission part owing to the conductive system, accordingly, the circuits can be simplified, and the electric spindle is safe and reliable in structure.

Description

technical field [0001] The invention relates to an electric spindle with a detection signal transmission structure, in particular to an electric spindle with a cutting process monitoring system. Background technique [0002] Machining signal feedback is often one of the important links in automated production, especially during cutting, the monitoring of information such as tool and contact status, workpiece processing status, and processing safety. These information feedback processes provide prerequisites for the realization of various subsequent monitoring systems; during the high-speed operation of the electric spindle, through the intelligent monitoring system to monitor whether there is a current or voltage signal, it can be judged whether the tool is in contact with the workpiece or not. It can be used as the initial condition for machining tool setting or the termination condition for machining completion; at the same time, during the high-speed operation of the elec...
