(57) [Summary] [Purpose] When press-fitting an annular part to the upper end of a shaft-shaped workpiece,
To prevent the upper end surface of a shaft-like workpiece and the upper surface of an annular component from being on the same plane even if there is variation in the length dimension of the shaft-like workpiece. [Structure] An elevating body having a cylindrical press-fitting punch having a press-fitting portion at its lower end is vertically disposed above a positioning jig that holds a shaft-like workpiece upright so as to be able to rise and fall. Inside this press-fit punch,
A guide pin having a small diameter pin part into which the annular part is fitted and held is slidably accommodated, and the small diameter pin part is protruded and retractably penetrated into the center of the lower end press-fitting part of the press-fitting punch. The guide pin is always urged downward by an elastic body, so that the opposing surfaces of the elevating body and the guide pin are opposed to each other at a predetermined interval so as to be able to abut each other. When the annular part is press-fitted into the upper end of the shaft-like workpiece, the press-fitting punch is moved up and down after the upper end of the shaft-like workpiece collides with the small-diameter pin part of the guide pin in conjunction with the lowering movement of the elevating body. The guide pin is lowered against the biasing force of the elastic body until the facing surfaces of the body and the guide pin come into contact with each other.

【００２４】 流体圧シリンダ（２２）のシリンダロッド（２３）が退入して、昇降体（２７ ）が上昇端に保持された状態では、圧縮スプリング（４０）のバネ力により圧入 パンチ（３４）の取付鍔部（３５）は昇降体（２７）の取付板（２６）に圧接し 、又押圧スプリング（４９）のバネ力によりガイドピン（４２）は下方に付勢さ れ、その小径ピン部（４４）の先端が圧入パンチ（３４）の貫通孔（３７）から 所定寸法突出する。[0024] The cylinder rod (23) of the fluid pressure cylinder (22) retracts and lifts the elevating body (27). ) is held at the rising end, it is press-fitted by the spring force of the compression spring (40). The mounting flange (35) of the punch (34) is pressed against the mounting plate (26) of the elevating body (27). Also, the guide pin (42) is urged downward by the spring force of the pressing spring (49). The tip of the small diameter pin portion (44) is inserted through the through hole (37) of the press-fit punch (34). Protrudes by a predetermined distance.
【００２５】 そして、上記ガイドピン（４２）の小径ピン部（４４）の先部に環状部品（６ ）を適宜の手段により嵌合保持させると、流体圧シリンダ（２２）のシリンダロ ッド（２３）が突出して昇降体（２７）が下降する。昇降体（２７）の下降によ り、ガイドピン（４２）の小径ピン部（４４）の位置決め凸部（４８）が軸状ワ ーク（３）の小径軸部（５）の位置決め凹部（４７）に嵌入し、小径ピン部（４ ４）と小径軸部（５）の環状端面が衝合する。[0025] An annular component (6 ) are fitted and held by appropriate means, the cylinder rod of the fluid pressure cylinder (22) The head (23) protrudes and the elevating body (27) descends. Due to the descent of the elevating body (27) The positioning convex portion (48) of the small diameter pin portion (44) of the guide pin (42) The small diameter pin part (4) fits into the positioning recess (47) of the small diameter shaft part (5) of the arc (3). 4) and the annular end surface of the small diameter shaft portion (5) abut against each other.
【００２６】 上記小径ピン部（４４）と小径軸部（５）とが衝合したのちも昇降体（２７） が下降すると、図２に示すように、圧縮スプリング（４０）が圧縮されて、昇降 体（２７）の環状溝（２９）と圧入パンチ（３４）の取付鍔部（３５）の上下方 向に対向する面が当接し、連通孔（４１）が閉塞される。[0026] Even after the small diameter pin part (44) and the small diameter shaft part (5) collide, the elevating body (27) When the is lowered, the compression spring (40) is compressed, as shown in Figure 2, and the Above and below the annular groove (29) of the body (27) and the mounting flange (35) of the press-fit punch (34) The opposing surfaces abut, and the communication hole (41) is closed.
【００２７】 さらに上記昇降体（２７）が下降すると、ガイドピン（４２）と軸状ワーク（ ３）とが衝合しているので、圧入パンチ（３４）が、昇降体（２７）と一体とな って押圧スプリング（４９）のバネ力に抗して、環状当り面（４５）がガイドピ ン（４２）のストッパ面（４６）に当接するまで下降する。この圧入パンチ（３ ４）の下降により、図２に示すように、ガイドピン（４２）の小径ピン部（４４ ）が圧入パンチ（３４）の貫通孔（３７）に退入するので、小径ピン部（４４） に嵌合保持されていた環状部品（６）は圧入パンチ（３４）の圧入部（３６）で 押圧されて軸状ワーク（３）の小径軸部（５）に圧入される。[0027] When the elevating body (27) further descends, the guide pin (42) and the shaft-like workpiece ( 3), the press-fit punch (34) is integrated with the elevating body (27). The annular contact surface (45) is pressed against the guide pin against the spring force of the pressing spring (49). It descends until it comes into contact with the stopper surface (46) of the ring (42). This press-fit punch (3 4), the small diameter pin portion (44) of the guide pin (42) is lowered, as shown in FIG. ) retracts into the through hole (37) of the press-fit punch (34), so the small diameter pin part (44) The annular part (6) that was fitted and held in the press-fitting part (36) of the press-fitting punch (34) It is pressed and press-fitted into the small diameter shaft portion (5) of the shaft-shaped workpiece (3).
【００２８】 このように上記環状部品（６）は、軸状ワーク（３）の小径軸部（５）とガイ ドピン（４２）の小径軸部（５）との衝合後、昇降体（２７）の環状当り面（４ ５）とガイドピン（４２）のストッパ面（４６）とが当接するまで、圧入パンチ （３４）により押圧され、環状部品（６）の圧入ストローク（ｂ）は常に一定と なる。したがって、軸状ワーク（３）の長さ寸法にバラツキがあっも、環状部品 （６）は常に軸状ワーク（３）の小径軸部（５）の定位置に圧入されるので、図 ３に示すように、小径部（５）の上端面（５ａ）と環状部品（６）の上面（６ａ ）とを確実に同一平面に保持することができる。[0028] In this way, the annular part (6) is connected to the small diameter shaft part (5) of the shaft-like workpiece (3). After colliding with the small diameter shaft portion (5) of the dowel pin (42), the annular contact surface (4) of the elevating body (27) 5) until the stopper surface (46) of the guide pin (42) comes into contact with the press-fit punch. (34), and the press-fitting stroke (b) of the annular part (6) is always constant. Become. Therefore, even if there are variations in the length of the shaft-shaped workpiece (3), the annular part (6) is always press-fitted into the fixed position of the small diameter shaft part (5) of the shaft-shaped workpiece (3), so 3, the upper end surface (5a) of the small diameter part (5) and the upper surface (6a) of the annular part (6) ) can be reliably held on the same plane.
【００２９】[0029]
本考案によれば、軸状ワークの長さ寸法にバラツキがあっても、ワークの上端 部への環状部品の圧入時、この上端部の端面と環状部品の上面とを確実に同一平 面に保持することができ、上記上端面と上面が不揃いになるのを防止することが できる。しかも、従来のような環状部品のストロークの補正機構を別途に必要と せず、構造が簡単であり、製作が容易であって、コストが安い。 According to the present invention, even if there are variations in the length of the shaft-like workpiece, the upper end of the workpiece can be When press-fitting an annular part into It can be held on the surface and prevent the upper end surface and the top surface from becoming uneven. can. Moreover, it does not require a separate stroke correction mechanism for the annular part as in the past. It has a simple structure, is easy to manufacture, and is inexpensive.
