Abstract

PURPOSE:To detect the wearing or the like of a tool edge easily by a method wherein a movable arm is provided near the main spindle chuck of the lathe and a pressure sensor is provided at the free end of the arm in order to compare the moving distances of the tool edge until it contacts with the pressure sensor before and after the using of the tool. CONSTITUTION:A gear box 15 is provided near the upper part of the chuck 5 of the lathe so as to be projected out of the main body 1a of the lathe and two pieces of rotating shafts 18, 19 are provided in the gear box while the L-shaped arm 14 is fixed to the end of the rotating shaft 19. A switch box 21 at the tip end of the arm 14 is provided with the pressure sensor 22. Both of said rotating shafts 18, 19 are connected through gears 25, 25 while the rotating shaft 18 is connected to a motor 27 through a chain. According to this method, the edge 7a of the tool 7 is moved toward the pressure sensor 22 by a given distance after the working of the work piece, and it is decided that some abnormality, such as the wearing or the like of the tool edge 7a, is caused, when the tool edge 7a does not contact with the pressure sensor 22 and the sensor 22 is not closed.

Description

【発明の詳細な説明】 この発明は旋盤に関し、詳しくは、工具の刃先の破損あ

ある。Chips and wear and tear on the cutting edge of tools on lathes are extremely bad, as if you continue to do the do-it-yourself process without realizing it, you will end up producing a large number of defective workpieces, which is extremely bad. It is difficult to visually inspect these tools in a short time, and in the case of a lathe with many tools attached to the turret tool rest, it is even more difficult and takes a long time for the operator to inspect all of the tools. This is a task that requires a lot of effort.

のである。Therefore, the present invention provides an arm near the main spindle chuck of a lathe, the free end of which is movable between the first neck in the AfT direction of the main spindle chuck and a lateral position, and the movable free end of the arm. By providing a pressure-sensitive sensor that closes with a minute pressure and comparing the distance traveled until the cutting edge of the tool comes into contact with the pressure-sensitive sensor at the end of the arm before and after using the tool, or By detecting whether the cutting edge reaches or does not reach the pressure-sensitive sensor when the tool is moved the same distance before and after use,
This allows for easy and quick verification of tool cutting edges.

ンサー（２２）が閉成するまで移動するのである。In other words, the distance traveled by the turret (6) until the tool cutting edge (7a) contacts the pressure-sensitive sensor (22) is measured and recorded before the workpiece is moved, that is, before the tool is used. After using the tool, instead of moving the turret (6) by the recorded distance, the cutting edge (7a) contacts the pressure sensor (22) and the sensor (22) is activated as before use. It moves until it closes.

そして、その際のタレット（６）の移動距離を工具使用
前の移動距離と比較し、異っている場合には刃先破損等
