Description
【考案の詳細な説明】
本考案は主としてエンジン用のクランクシャフトのピン
部或はジャーナル部をワークとし、これにローラバニシ
ング加工を施す装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention mainly relates to an apparatus that uses a pin portion or a journal portion of a crankshaft for an engine as a workpiece and performs roller burnishing on the workpiece.
従来この種装置において１本体に軸支されるバニシンク
ローラと、その前方のワークとはその軸線が互に平行す

図示の状態から第５図示の状態となるべきもので、か＼
るものではその押潰しに相当大きな力を必要とし、従っ
て装置は全体として大型化し勝ちである不都合を伴う。Conventionally, in this type of equipment, the burnishing roller, which is pivotally supported by one main body, and the workpiece in front of it are generally in a relationship in which their axes are parallel to each other, and thus, due to mutual pressure contact between the two, In this case, the small protrusions that already exist on the circumferential surface of the workpiece are crushed vertically from the front surface by the roller and the fourth protrusion is formed.
The state shown in the diagram should change to the state shown in the fifth diagram.
However, a considerable amount of force is required to crush the device, which tends to increase the size of the device as a whole.
本考案はか＼る不都合のない装置を得ることをその目的
としたもので、本体１に軸支されるバニシングローラ２
をワークａの周面と互に圧接させる式のものにおいて、
該ローラ２の軸線Ｘ−Ｘと。The purpose of the present invention is to obtain a device that does not have such inconveniences.
In the type of pressure contact with the circumferential surface of workpiece a,
and the axis X-X of the roller 2.
該ワークａの軸線Ｙ−Ｙとを互に平行する平面内の互に
傾斜する関係位置とすると共に該ローラ２の周面を該ワ
ークａとの接触弧にならったりつみ状に形成することを
特徴とする。The axes Y-Y of the workpiece a are arranged in mutually parallel planes at mutually inclined positions, and the peripheral surface of the roller 2 is formed to follow the arc of contact with the workpiece a or to form a knot. Features.
第１図乃至第３図はその１例を示すもので、図示のもの
では本体１を前進させてローラ２をワークａ側に圧接さ
せるようにしたが、これに代えワークａ側を移動させる
ようにすることも可能である。Figures 1 to 3 show an example of this. In the illustrated example, the main body 1 is moved forward and the roller 2 is brought into pressure contact with the workpiece a side, but instead of this, the workpiece a side is moved. It is also possible to
尚ワークａは一側のチャックｂと他側の七ンメＣとで周
外側から支承されてこれに駆動廻転が与えられるように
した。The workpiece a was supported from the outside circumferentially by a chuck b on one side and a seven-piece c on the other side, so that driving rotation was applied to the workpiece a.
軸線Ｘ−Ｘと軸線Ｙ−Ｙとの関係は例えば第２図に明示
するように互に角度θだけ傾斜する。The relationship between the axis X--X and the axis Y--Y is such that they are inclined to each other by an angle .theta., as clearly shown in FIG. 2, for example.
その作動を説明するに、ワークａを廻転させつつこれに
ローラ２圧接させるものでこの点は従来のものと特に異
らないが、この場合両者は互に傾斜した圧接関係に存す

２によυ側方から押し潰される状態となる。To explain its operation, two rollers are brought into pressure contact with the workpiece a while rotating, and this point is not particularly different from the conventional one, but in this case, the two exist in an inclined pressure relationship with each other, and thus As a result, the small protrusions on the circumferential surface of the workpiece a are crushed by the roller 2 from the υ side.
この状態は例えば第６図示の通りである。This state is, for example, as shown in FIG.
このように本考案によるときは軸線Ｘ−Ｘと軸線Ｙ−Ｙ

ローラ２の周面はたいこ状をなすものでこれに所定の接
触長を得られて不都合がない等の効果を有する。In this way, according to the present invention, the axis X-X and the axis Y-Y
This is a type in which the small protrusions on the side of the workpiece a are crushed from the side by tilting them to each other.Compared to the conventional crushing in the vertical direction, a small pressing force is sufficient, making it possible to downsize the equipment. The circumferential surface of the roller 2 is in the shape of a cone, and has the advantage that a predetermined contact length can be obtained without causing any inconvenience.
