Abstract
The invention relates to a system for monitoring a shaft current. When a machine tool is in the drilling technique of workpieces, a device for clamping the workpieces is arranged on a rotary shaft; after the workpieces are fixed, holes are processed by rotating the rotary shaft; when the rotary shaft is rotated, the rotating speed thereof is very quick, so shaft current is generated; most of components on the machine tool are made of metal, they are easily conductive and very dangerous, so the shaft current need be neutralized; because the shaft current of the rotary shaft is not determined in operation, the shaft current cannot be accurately measured and totally neutralized, the system has great potential risks. The system for monitoring shaft current comprises a CPU and a power supply, wherein a current sensor is arranged in the monitoring system. The operator can randomly neutralize the shaft current according to information on the displayer at any time, and thus the machine tool processing is more safer.
Description
Technical field
The invention belongs to Machining Technology field, relate to shaft current monitoring system.
Background technology
Lathe is in the bore process of workpiece, it is all the device that holding workpiece is set on turning cylinder, after workpiece is fixing, realize the processing in hole by the rotation of rotating shaft, in the rotation process of rotating shaft, because the rotating speed of rotating shaft is very fast, can produce shaft current, because the parts major part on lathe is all metallic article, be easy to conduction, abnormally dangerous, thus just shaft current need to be neutralized, because rotating shaft shaft current is in the course of the work uncertain, therefore cannot measure accurately shaft current electric current is neutralized completely, have very large potential safety hazard.
Summary of the invention
The object of this invention is to provide one Accurate Measurement shaft current monitoring system in real time.
The technical solution adopted in the present invention is that shaft current monitoring system, comprises CPU and power supply, it is characterized in that: in described monitoring system, be provided with current sensor.
Described current sensor is connected with converter, and converter is connected with amplifier, and amplifier is connected with CPU.
On described CPU, be connected with display.
The invention has the beneficial effects as follows: in monitoring system of the present invention, be provided with current sensor, the current information that current sensor collects sends CPU to by converter and amplifier, CPU sends to the display being connected with CPU after current information is for further processing, operating personnel just can, according to the random natural axis electric current at any time of the information on display, make machine tooling safer like this.
