The utility model relates to a tool wear monitoring and alarming device for a numerically controlled lathe, which comprises an optical fiber sensor and a monitoring and alarming module. The workpiece maintains a certain gap with the workpiece; the monitoring and alarm module includes a stabilized power supply, a signal amplification unit, a data processing unit, and a display and alarm unit. The regulated power supply provides the required DC power for the light-emitting diodes. The signal amplification unit amplifies the monitoring signal output by the phototransistor. The data processing unit takes the single-chip microcomputer as the core and is responsible for A/D conversion and data analysis of the monitoring signal. When the monitoring signal exceeds the threshold, an audible and visual alarm signal is sent through the display and alarm unit. The utility model can effectively identify the wear state of the cutting tool by monitoring the change of the processed surface roughness of the turning parts in real time, which is beneficial to ensure the processing quality of the mass-produced parts.
Description
Technical field
The utility model relates to metal cutting tool wear measurement field, particularly a kind of numerically controlled lathe tool wear monitoring alarm.
Background technology
Numerically controlled lathe is widely used a kind of Metal Cutting Machine Tool in the machine-building.In the process, the wearing and tearing of cutter are divided into two types: normal wear (cutter weares and teares gradually) and heel and toe wear (tipping, turned or blade is whole cracked suddenly).At present, mainly lean on workman's observation and experience for the monitoring of tool wear; Also there are many scholars to carry out the research of tool wear monitoring aspect, as with the correlated characteristic of CCD imaging observation cutter VOLUME LOSS, with the breakage of calibrate AE sensor monitoring cutter etc., but all do not get into practical application.
Summary of the invention
The utility model is intended to overcome the deficiency of above-mentioned prior art, for the numerically controlled lathe production scene provides a kind of tool wear monitoring alarm.
The utility model provides a kind of numerically controlled lathe tool wear monitoring alarm, comprises sensor and monitoring, alarming module, and described sensor is a reflection-type optical fibre sensor, is installed on the knife rest perpendicular to workpiece, with workpiece maintenance certain clearance; Described monitoring, alarming module comprises voltage-stabilized power supply, signal amplification unit, data processing unit, display alarm unit, and when monitor signal surpassed threshold value, buzzer and LED through the display alarm unit sent the sound and light alarm signal.
The utility model discerns effectively the state of wear of cutter through the variation of real-time monitoring turning part machined surface roughness, helps guaranteeing to produce in batches the crudy of part.
Description of drawings:
Fig. 1 is the theory diagram of the utility model.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, the utility model provides a kind of numerically controlled lathe tool wear monitoring alarm, comprises Fibre Optical Sensor 1 and monitoring, alarming module 2.Fibre Optical Sensor 1 is a reflection-type optical fibre sensor; Form by Light-Emitting Diode, incident optical bundle, mirror based fiber optica bundle, phototriode etc.; Be installed on the knife rest perpendicular to workpiece, and workpiece keeps certain clearance (between 1 to 2 millimeter, confirming according to incident optical beam diameter value).Monitoring, alarming module 2 comprises voltage-stabilized power supply, signal amplification unit, data processing unit, display alarm unit.Voltage-stabilized power supply is that Light-Emitting Diode provides required dc source; Signal amplification unit amplifies the monitor signal of phototriode output; Data processing unit is core with the single-chip microcomputer; Be responsible for monitor signal is carried out A/D conversion and data analysis; When monitor signal surpasses threshold value (after lathe tool reaches the blunt standard usually or take place unexpected tipping, turned and blade whole cracked after, workpiece surface roughness significant change will occur, exceed normal scope), send the sound and light alarm signal through the buzzer and the LED of display alarm unit; Wait for workman's affirmation and stop processing, also can after nobody replys a period of time, directly suspend the motion of numerically controlled lathe electric driving tool post.
