1台の機械で複数の異なる加工方法を行うことができる複合加工機は公知であり、例えば特許文献1にはピストンリングの内外周面加工と切割加工を可能にした複合加工機を開示する。
しかし、これまでに2つのワークを突き合せて、この2つのワークの端面に同時に端面加工できる複合加工機は報告されていない。
A multi-tasking machine capable of performing a plurality of different processing methods with a single machine is known. For example,
However, there has been no report on a multi-tasking machine capable of matching two workpieces and simultaneously machining the end surfaces of the two workpieces.
本発明は、ワークの端面に側方から凹部加工を行う場合に加工面の品質が高く、生産性に優れた複合加工機及びその加工方法の提供を目的とする。 An object of the present invention is to provide a multi-tasking machine having a high processing surface quality and excellent productivity when a recess processing is performed on an end surface of a workpiece from the side, and a processing method thereof.
本発明に係る複合加工機は、2つのワーク端面に同時加工が可能であり、それぞれ主軸モータにて回転制御されたL,Rチャック手段を対向配置し、前記2つのL,Rチャック手段は、それぞれ少なくとも一つ以上の刃物台が対応配置されるとともにL及びRチャック手段の少なくとも一方は前進後退制御され、Lチャック手段にてチャックした第1ワークとRチャック手段にてチャックした第2ワークとを突き合せ静止させた状態でワークの側面から突き合せ部に孔を明ける穿孔手段を有することを特徴とする。
L,Rチャック手段は回転することでバイト等にて旋削が可能であり、静止した状態でフライス削りやドリル加工が可能である。
The multi-tasking machine according to the present invention is capable of simultaneous machining on two workpiece end faces, each of which has L and R chuck means that are rotationally controlled by a spindle motor, opposed to each other. At least one tool post is disposed correspondingly, and at least one of the L and R chuck means is controlled to move forward and backward, and a first work chucked by the L chuck means and a second work chucked by the R chuck means, It has a perforating means for making a hole in the abutting portion from the side surface of the workpiece in a state where the abutment is kept stationary.
The L and R chuck means can be turned with a tool by rotating, and can be milled or drilled in a stationary state.
このような複合加工機を用いると、それぞれ主軸モータにて回転制御されたL,Rチャック手段を対向配置し、前記2つのL,Rチャック手段は、それぞれ少なくとも一つ以上の刃物台が対応配置されるとともにL及びRチャック手段の少なくとも一方は前進後退制御され、Lチャック手段にて第1ワークの凹部及び内周加工を施し、Rチャック手段にて第2ワークの凹部及び内周加工を施し、L,Rチャック手段のうち少なくとも一方を前進制御し、第1及び第2ワークの端面同士を突き合せ静止させた状態で当該突き合せ部に側面から穿孔加工を施すことにより、2つのワーク端面に同時に凹部加工行うことができる。
ここで穿孔加工はドリル加工やエンドミル加工等が例として挙げられる。
When such a multi-tasking machine is used, L and R chuck means whose rotation is controlled by a spindle motor are arranged opposite to each other, and the two L and R chuck means are arranged to correspond to at least one tool post. At the same time, at least one of the L and R chuck means is controlled to advance and retreat, and the L chuck means performs the recess and inner peripheral processing of the first workpiece, and the R chuck means performs the recess and inner peripheral processing of the second workpiece. Two workpiece end faces are formed by controlling the forward movement of at least one of the L, R, and R chuck means and performing a perforating process on the abutting portion from the side face in a state where the end faces of the first and second workpieces are abutted and stationary. Simultaneously, recess processing can be performed.
Here, examples of drilling include drilling and end milling.
本発明に係る複合加工機にあっては、2つのワークの端面を突き合せて、側部からこの突き合せ部に穿孔加工を行うことができるので、1つのワーク毎に端面加工を行うのに比較して刃先の振れが小さく、ビビリの発生が少ないので、加工面の寸法精度や切削表面品質が高い。
また、2つのワークに同時に加工を施すので生産性が高い。
In the multi-tasking machine according to the present invention, the end faces of two workpieces can be butted and the drilling can be performed from the side to the butted portion. Compared with the small runout of the cutting edge and less chatter, the dimensional accuracy of the machined surface and the cutting surface quality are high.
In addition, productivity is high because two workpieces are processed simultaneously.

その時にはLチャック手段に次のワークW3がチャック保持され、外形加工が施され、その後は先に示したように順次加工が施される。
An example of a procedure for processing a product (workpiece) having a semicircular recess a in side view on the end face of a bottomed cylindrical body W as shown in FIG. 5, for example, using the combined processing machine according to the present invention will be described.
As shown in FIG. 1 (a), a first workpiece W 1 made of a columnar material is chucked and held by an L chuck means 10, and is rotated by an L side spindle 11.
Then processing the outer shape of the outer peripheral portion or the like of the workpiece W 1 in FIG. 1 (b) of bytes such as shown in the L-side tool 36.
When the outer shape machining of the workpiece W 1 is completed, R chuck means 20 is advanced in the direction of S 1 as shown in FIG. 1 (c), picking up the workpiece W 1.
R chuck means 20 is retracted in the direction of S 2, L chuck means 10 chucks holding the following second workpiece W 2.
In this state, subjected to recess and inner circumferential machining in the Z-axis direction in the first work W 1 is a byte such as R-side tool 47 held by R chuck means as shown in FIG. 2 (e), L chuck means 10 is carried out in the recess and the inner peripheral processing destination of the second workpiece W 2 Z-axis direction by the R-side tool 47 bytes, and the like.
Then R chuck means 20 as shown in FIG. 2 (f) is advanced in the direction of the S 3, the first workpiece W 1 and butting the end face of the second workpiece W 2, the drill from the side in its quiescent state Drilling is performed with a
A perspective view of this state is shown in FIG. 4A, and a cross-sectional view is shown in FIG.
When the end face recess machining of the workpiece is completed, R chuck means 20 is retracted in the direction indicated in S 4 in FIG. 2 (g).
First work W 1 which process has been completed is discharged, the second workpiece W 2 to the inner periphery and the end surface recess machined finished FIG 3 (i), (j) , delivered to the R chuck means as shown in (k) Then, the outer shape processing on the back side is performed by the
Then the next workpiece W 3 to L chuck means is a chuck held, is decorated outline processing, then sequentially processed as indicated above is applied.
本発明の特徴は、図4に示したように第1ワークW1と第2ワークW2とを静止した状態で突き合せ、側部から穿孔手段にて、両方向のワークに凹部が同時に形成されるように加工する点にある。
1つのワーク単独にて端面に側部から加工すると刃先が外側に逃げ、ビビリが発生しやすいが、このように2つのワークを突き合せて加工するとビビリ等の発生が生じにくく、加工精度が向上する。
なお、穿孔工具としてドリルを用いて説明したが、エンドミル等の各種工具を用いて、半円形状のみならず、各種凹部形状を形成することも可能である。
The feature of the present invention is that, as shown in FIG. 4, the first workpiece W 1 and the second workpiece W 2 are abutted in a stationary state, and concave portions are simultaneously formed in the workpieces in both directions by the punching means from the side portion. It is in the point to be processed.
If a single workpiece is machined from the side on the end face, the cutting edge will escape to the outside and chattering is likely to occur. However, if two workpieces are brought into contact with each other in this way, chattering is less likely to occur and machining accuracy is improved. To do.
In addition, although demonstrated using the drill as a drilling tool, it is also possible to form not only a semicircle shape but various recessed shape using various tools, such as an end mill.
