Online automatic detecting device for abrasion state of rotating body tool

Abstract

The invention discloses an online automatic detecting device for an abrasion state of a rotating body tool. The online automatic detecting device comprises a device base, a tool optical detecting system, a concentrated control system and a tool abrasion alarming system. The tool optical detecting system is a planer array type image sensor system, and comprises a tool entire measuring device and a cutting blade partial measuring device. Image data of an entire tool and partial detail image data in a cutting blade abrasion area are collected, so as to determine a position, a posture and an abrasion state of a tool cutting blade. A calibration target material is mounted on a lathe spindle of the rotating body tool, so that the tool entire measuring device and the cutting blade partial measuring device can be pre-calibrated on line before the measurement. The online automatic detecting device provided by the invention is applicable to a device for automatically carrying out abrasion detection at a rotating state of the rotating body tool, so that the reliability in a machining process is ensured. Therefore, the rotating body tool which is widely used in the production can be reasonably utilized, so the production cost is reduced, the machining efficiency is improved, the consumption of a tool metal material is reduced, and the natural sources are saved. The online automatic detecting device has important meanings.

Description

technical field [0001] The invention relates to a mechanical processing detection device, in particular to an automatic and on-line detection device for the wear state of a tool of a rotary body. Background technique [0002] The wear condition of the tool has a key influence on the precision and manufacturing cost of metal cutting. When the wear reaches a certain level or it is damaged, the tool needs to be replaced. If the replacement is too early, it will increase unnecessary tool consumption and production costs. If it is too late, It may lead to out-of-tolerance workpiece dimensions and surface scratches, and may even injure the operator and damage the machine tool in severe cases. Therefore, it is necessary to establish an online tool condition monitoring system to automatically obtain the actual wear condition of the cutting edge through sensors. [0003] Due to the complexity and gradualness of the wear process, the online automatic detection technology of tool wear ...

AI Technical Summary

Problems solved by technology

[0004] 1. The on-line automatic detection of tool wear on the rotary body cannot be realized. It needs to be manually assisted to complete the measurement or remove the blade for offline measurement when the spindle is stopped, which greatly increases the standby time and reduces production efficiency;

[0005] 2. The manual detection process is time-consuming and cannot achieve 100% cutting edge detection, nor can it be integrated with automated CNC processing technology, which affects the reliability of the processing process

[0006] 3. The existing device for detecting the wear of the rotary tool is not ideal enough, and cannot effectively reduce the consumption of the metal material of the tool, and the equipment structure is relatively complicated, which cannot meet the actual needs
