Abstract

<P>PROBLEM TO BE SOLVED: To provide an XY-coordinate measuring instrument measuring XY-coordinates in the center of a ball of a ball end mill and measuring positional slippage of a coordinate of a knife edge of the ball end mill when it is straight and when it is inclined. <P>SOLUTION: This XY-coordinates measuring instrument is devised so as to measure moving quantity of a square inner frame when the knife edge of the ball end mill is pressed on the square inner frame by: fixing a square outer frame A; placing the square inner frame B in the center of the inside of the square outer frame A; uniformly connecting four corners of the inside of the outer frame to a supporting part C having a springing property; making the square inner frame free to move in parallel and reciprocally by about one millimeter in the X and Y directions; and making probes D, L of a dial gage contact with the outside of the square inner frame in the X and Y directions. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

この発明はフライス盤における3次元形状物の加工の際に、図(4)のアングルヘッドのアタッチメントを取り付けて、回転切削刃物であるボールエンドミルをホルダーに取り付け、傾斜させて切削加工をするとき、ボールエンドミルの ボール中心のXY座標を計測し、ボールエンドミルの刃先の座標を、図(5)の左右の図の様にまっすぐの場合と傾斜させた場合との位置のずれを計測する器具である。  When machining a three-dimensional object in a milling machine, the present invention attaches the attachment of the angle head shown in FIG. (4), attaches a ball end mill, which is a rotary cutting blade, to the holder, This is an instrument that measures the XY coordinates of the ball center of the end mill, and measures the positional deviation between the case where the ball end mill's blade tip is straight and tilted as shown in the left and right diagrams of FIG.

従来は傾斜させない場合の刃物長の測定器はあったが、XとY方向を計測する測定器は見あたらなかった。近年は作業を効率化する必要があり、金型等の立体形状物を切削加工するときに刃物を傾けると、長い刃物を必要とせず早く細部まで切削加工ができ、後行程での加工工数を大幅に削減出来て効率化が計れるものである。それは図(3)のまっすぐにボールエンドミルを取り付けたときの刃物の必要長さと、図(4)の如く アングルヘッドアタッチメントによりボールエンドミルを傾斜させて
加工するときの刃物の長さは歴然と差が出来る。短い刃物で切削すれば刃物に剛生があるので早く切削加工を行うことが出来る。又短い標準の長さの刃物の方が価格も安価でありコストダウンができる。
Conventionally, there was a measuring instrument for the length of the blade when not tilted, but no measuring instrument for measuring the X and Y directions was found. In recent years, it is necessary to improve work efficiency. If the tool is tilted when cutting a three-dimensional object such as a die, it can be cut to details quickly without the need for a long tool, reducing the number of processing steps in the subsequent process. It can be greatly reduced and efficiency can be improved. The required length of the cutter when the ball end mill is attached straight as shown in Fig. (3) and the length of the cutter when the ball end mill is tilted by the angle head attachment as shown in Fig. (4) can be clearly different. . If you cut with a short blade, you can cut quickly because the blade has rigidity. Also, the shorter standard length blade is cheaper and can be reduced in cost.

発明の詳細な説明Detailed Description of the Invention

図(1)の外枠(A)を固定し、その内側の中心に内枠(B)を置き、外枠の内側4隅と内枠の四隅をバネ性を持たせた支持部(C)で均等に連結させて、(B)の内枠をXとY方向に1ミリ程平行反復移動を可能とさせて、内枠(B)の外側に図の如くXとY方向にダイヤルゲージの測定子(D)を接触させ、内枠(B)にボールエンドミルの刃先を押し当てたときの、内枠(B)の移動量を計測出来るように すればボールエンドミルの刃物中心のX・Y方向の座標値が簡単に測定出来るものである。又 刃物の長さ方向の測定には、従来からある刃物長測定器を設置すれば3軸の座標値が一度に計測出来るものである。また内枠(B)の外郭4隅の支持部(C)の代わりにゴム等の反復性の材料又はコイルスプリング等を装着しても効果を出すこともできる。
ダイヤルゲージの代わりにピックテスターでも代用できる。
The outer frame (A) of FIG. (1) is fixed, the inner frame (B) is placed at the center of the inner frame, and the inner four corners of the outer frame and the four corners of the inner frame are provided with spring properties (C) The inner frame of (B) can be repeatedly moved in parallel in the X and Y directions by about 1 mm, and the dial gauge is placed outside the inner frame (B) in the X and Y directions as shown in the figure. If the measuring element (D) is in contact and the tip of the ball end mill is pressed against the inner frame (B), the amount of movement of the inner frame (B) can be measured. The coordinate value of the direction can be easily measured. For measurement in the length direction of the cutter, if a conventional cutter length measuring device is installed, the coordinate values of three axes can be measured at once. Further, it is possible to obtain an effect even if a repetitive material such as rubber or a coil spring is attached instead of the support portions (C) at the four corners of the outer frame (B).
A pick tester can be substituted for the dial gauge.

発明の効果The invention's effect

フライス盤に図(4)のアングルヘッドアタッチメントを取り付けてボールエンドミルを装着して、任意の角度に傾斜させて、金型等の3次元形状物を切削する時に、刃先の中心座標を計算値で正確に傾斜移動量を把握することは、アタッチメントの角度目盛りだけで0.01ミリ単位の位置の把握はほとんど不可能であった。本発明のXY座標計測器を使えばダイヤルゲージの0.01単位での計測が簡単にできる。
計測方法は本体をフライス盤のベッドの左右、又は前後方向に本体面をマグネット又はボルト等で正確に平行に固定取り付けし、あらかじめ本計測器の中心を求めておいて、次にアングルヘッドアタッチメントで傾けたボールエンドミルの刃先を図(2)のようにを内枠(B)に接触させ、わずかに圧力を加えたときのダイヤルゲージの長針が運動を始める位置を読みとる
このとき刃先を手動でわずかに回転させて最も高い位置をもとめるが重要である。これをX、Yの2方向に実施する。その位置から内枠(B)の内寸の半分とボールエンドミルの半径値を差し引いた値を接触させた逆方向に移動した位置がそのボールエンドミルの刃先のボール中心の座標位置である。
When the angle head attachment shown in Fig. (4) is attached to the milling machine, the ball end mill is mounted, and the tool is tilted at an arbitrary angle to cut the center coordinates of the cutting edge with the calculated value when cutting a three-dimensional object such as a die. However, it is almost impossible to grasp the position in units of 0.01 mm only with the angle scale of the attachment. If the XY coordinate measuring instrument of the present invention is used, the dial gauge can be easily measured in 0.01 units.
The measuring method is to fix the main body to the left and right or the front and rear direction of the milling machine bed in parallel with magnets or bolts, etc., find the center of this measuring instrument in advance, and then tilt it with the angle head attachment. The tip of the ball end mill is brought into contact with the inner frame (B) as shown in Fig. (2), and when the pressure is slightly applied, the position where the long hand of the dial gauge begins to move is read manually. It is important to rotate to find the highest position. This is performed in two directions, X and Y. The coordinate position of the ball center of the cutting edge of the ball end mill is the position moved in the opposite direction where the half of the inner dimension of the inner frame (B) is subtracted from the position and the value obtained by subtracting the radius value of the ball end mill.
