Description

Displacement measurement system of a rotary tool}

The present invention relates to a system for measuring the displacement of a rotary tool, and more particularly, to a rotary tool capable of measuring the displacement of a rotating tool to process a workpiece, thereby correcting the spindle of the tool and measuring the replacement cycle of the tool to maintain precision machining. It is about the displacement measurement system of

The cutting process using machine tools includes planing, side machining, hole machining, threading, etc. using various cutting tools. The tool is placed, and the spindle uses this tool to perform machining while exchanging the tool for the required machining. As a result, the machine tool can be operated faster and more quickly by storing a large number of tools.

The tool used in the above-described machine tool may change its length as the tool edge wears due to friction with the workpiece during processing, or may be damaged or broken due to non-uniform material of the workpiece, equipment operation mistake, or external factors during processing.

When a cutting tool has a plurality of cutting edges, damage or breakage of a plurality of tool inserts directly affects the workpiece. However, in the case of end mills, taps, drills, etc., since the number of cutting edges is small, damage to the cutting edge directly causes abnormalities in the workpiece and causes defects.

Therefore, since a cutting tool that has been used for a long time generates a machining error as much as the amount of wear, it is necessary to measure the length of the tool and correct the worn length.

In addition, since the main shaft moves in the axial direction due to bearing deformation caused by heat and centrifugal force during high-speed rotation, it is necessary to measure and correct the axial displacement of the main shaft.

Conventionally, in the detection of cutting tool breakage, measurement of length, and measurement of axial displacement of the main shaft, a tool mounted on the main shaft moves directly into contact with the shaft where the main shaft is installed using a limiter switch or touch sensor installed inside the machine, causing the sensor to When it is operated, there are various methods such as a method of converting the movement distance based on the point of time of operation, a method of measuring based on the time it takes for the laser scanned by the laser measuring device to reach the light receiver, and a method using an ultrasonic sensor.

However, the conventional methods described above simply detect the displacement of the tool by a simple on/off type, and cannot measure the displacement of the tool in real time during cutting, resulting in slow responsiveness and resulting in machining errors. There is a problem with doing it.
