本発明は中空パイプ状の被加工物の穴をワイヤ
を用いて仕上げるワイヤラツピツピング装置に関
する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a wire rapping device for finishing a hole in a hollow pipe-shaped workpiece using a wire.
従来のワイヤラツピツピング装置の概要を第１
図に示す。第１図中、中空パイプ状の被加工物１

矢印Ａに示すように動く。すなわちワイヤ２は回
転する被加工物１の穴中を摺動することとなり、
この時ワイヤに砥粒を与えることにより穴仕上げ
は進行する。しかしながらこの装置では、ワイヤ
２と被加工物１の摩擦が強く、ワイヤ２の移動と
共に被加工物１も摺動するため、主たる加工を与
えるワイヤ２と被加工物１間の相対的すべりが少
ない。そのため加工速度が遅く、また相対的すべ
りがランダムに発生するため一定の穴径まで仕上
げる時間にもバラツキが多いという欠点がある。 First, an overview of the conventional wire rack picking device.
As shown in the figure. In Fig. 1, hollow pipe-shaped workpiece 1
is passed through the wire 2 and rotated by being pressed against the rotating elastic roller 3. The tension T of the wire 2 is kept constant by a spring 5, and the wire 2 is moved as shown by an arrow A by a crank mechanism 4. In other words, the wire 2 slides through the hole of the rotating workpiece 1,
At this time, hole finishing progresses by applying abrasive grains to the wire. However, in this device, the friction between the wire 2 and the workpiece 1 is strong, and the workpiece 1 also slides as the wire 2 moves, so there is little relative slippage between the wire 2, which performs the main processing, and the workpiece 1. . Therefore, the machining speed is slow, and since relative slip occurs randomly, there is a drawback that the time required to finish a hole to a certain diameter varies widely.
上記欠点を減ずるため第２図に示すように、ス
トツパ５を設け、被加工物１の移動をさまたげ、
ワイヤ２との相対すべりを増加することも考えら
れるが、この場合被加工物１端面がストツパ５に
当つた際に被加工物１の回転がスムーズに行われ
なくなり、被加工物１の穴真円度が著しく悪化す
るという欠点がある。 In order to reduce the above drawback, as shown in FIG. 2, a stopper 5 is provided to prevent the movement of the workpiece 1,
It is also possible to increase the relative slippage with the wire 2, but in this case, when the end surface of the workpiece 1 hits the stopper 5, the workpiece 1 will not rotate smoothly, and the hole alignment of the workpiece 1 will be reduced. The disadvantage is that the roundness deteriorates significantly.
さらに、これらの装置では、ワイヤを摺動させ
るためのクランク機構４等が必要となるため、装
置全体も複雑となる。 Furthermore, these devices require a crank mechanism 4 and the like for sliding the wire, making the entire device complicated.
本発明は、以上の欠点を無くすため、単純な構

望の径にバラツキなくかつ真円度良好に仕上げる
ことのできるワイヤラツピツピング装置を提供す
ることを目的とする。 In order to eliminate the above-mentioned drawbacks, the present invention provides a wire-rap-pipping device that has a simple configuration, can finish holes in a large number of workpieces at a stable machining speed, to a desired diameter without variation, and with good roundness. The purpose is to provide.

分な相対すべりが生じ、加工時間の安定、仕上げ
穴径の安定、十分な真円度が得られる。 In the present invention, by arranging the linear body at an angle with respect to the rotation axis of the elastic rotating cylindrical body, the workpiece can be rotated on the linear body by the force given by the rotating elastic rotating cylindrical body. However, since it is made to move on its own, there is no need for a sliding mechanism for the linear body, making it mechanically simple, and sufficient relative sliding occurs between the workpiece and the linear body, resulting in stable machining time and Stable finished hole diameter and sufficient roundness can be obtained.
以下に本発明を実施例と共に述べる。 The present invention will be described below along with examples.

Further, the positional relationship between the wire 2 and the elastic roller 3 before passing the workpiece through the wire is shown in FIGS. 4 and 5. FIG. 4 is a view seen from direction A, and FIG. 5 is a view seen from direction B.

を引つ張られている。 The elastic roller 3 is rotated by a motor 8 via a pulley 6 and a belt 7. The wire 2 is an elastic roller 3
The height-adjustable pulleys 9 and 10 arranged at both ends of the roller allow the roller to be positioned at a constant distance from the roller rotating shaft 11 as shown in Fig. 4, and by θ° in the vertical direction as shown in Fig. 5. The presser foot 1 is tilted and supported.
2 is fixed at one end, and the other end is pulled by a weight 13.

The workpiece 1 is pressed against an elastic roller 3.

真円度の穴が得られる。 The forces acting on the workpiece are shown in FIGS. 6 and 7. 6 is a view seen from direction A in FIG. 3, and FIG. 7 is an enlarged view of the main part of FIG. 2. As can be seen from FIG. 6, a pressing force F' against the elastic roller 3 acts on the workpiece 1 due to the wire tension F. In this state, when the elastic roller 3 is rotated in the direction of the arrow as shown in FIG. 7, a sliding force G 2 is exerted along the wire 2 due to the force G 1 due to the friction between the elastic roller 3 and the workpiece 1 . That is, the workpiece 1
is passed through the wire 2, and the elastic roller 3 rotates continuously.
When the workpiece 1 is tilted by θ° and held in contact with the elastic roller 3, the workpiece 1 moves from left to right in FIG. In this case, when abrasive grains are applied to the wire 2, G 3 acts as a machining pressure on the workpiece 1, and as the workpiece 1 moves on the wire 2, the hole wrap finish of the workpiece 1 is performed. Furthermore, since the workpiece 1 moves while rotating, a hole with high roundness can be obtained.

ある。 The material of the elastic roller 3 is preferably a soft material such as sponge or rubber, or a material that is easily deformed such as a feather brush, but any material that does not apply forced force to the workpiece 1 may be used. The material of the wire 2 does not particularly matter, but it may be of sufficient strength to withstand the tension applied by the weight 13. It is desirable that the inclination θ between the elastic roller 3 and the wire 2 is small, and in this embodiment, it is 2°.
以上述べてきた実施例においては、第６図で理
解できるように被加工物１の位置によりF′は変

F′が弱くなり、それにつれてG2も減少するため
移動速度が遅くなることにもなる。 In the embodiments described above, as can be understood from FIG. 6, F' changes depending on the position of the workpiece 1, and when the workpiece 1 is near the center of the elastic roller,
As F′ becomes weaker, G 2 also decreases, resulting in slower movement speed.
この欠点を補うための実施例を第８図に示す。 An embodiment for compensating for this drawback is shown in FIG.

でスライドする。 Two blocks 14 pushing the wire 2 at both ends of the workpiece 1 are fixed to the holder 15, and the holder 15
slides at an arbitrary speed in the direction of movement of the workpiece 1 along with a belt 16 driven by a motor (not shown) on a guide rod 17 arranged parallel to the roller axis.

向上がはかれる。 That is, the wires 2 at both ends of the workpiece 1 are pushed toward the elastic roller 3 side by the block 14 while sliding in the moving direction of the workpiece 1, and the workpiece 1 is pressed at any position on the elastic roller 3. By keeping the force H constant and G 2 in FIG. 7 constant, the moving speed of the workpiece 1 is stabilized and the machining efficiency can be improved.

る。 As described above, in the present invention, since the linear body is arranged so as to have an inclination with the rotation axis of the elastic rotating cylindrical body, relative sliding between the linear body and the workpiece can be reliably obtained. Machining progresses at a faster and more stable speed than conventional methods, resulting in sufficient roundness and a stable hole diameter with no variation, resulting in stable machining time and eliminating the need for a conventional crank mechanism. First, the entire device can be simplified and downsized.
