【考案の詳細な説明】
本考案はフレームに軸支されるクランク軸にコ
ネクチングロツドを介して連結されるラムをフレ
ームに上下動自在に支持させたプレス機械におけ
るラム支持装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a ram support device for a press machine in which a ram, which is connected to a crankshaft supported by a frame via a connecting rod, is supported by the frame so as to be movable up and down.
この種装置においてはラムはその左右及び前後

ムに支承させているが、かゝるラムの側面の支持
は煩雑となる等の不都合を有していた。 In this type of device, in order to eliminate the ram's left-right and front-back inclinations, the ram uses special ball bearings to connect guide shafts on both left and right sides and in the center of the rear, as disclosed in Japanese Utility Model Publication No. 55-4157. Although the ram is supported by the frame through the ram, supporting the side of the ram is complicated and disadvantageous.
本考案はかゝる不都合を改良することを目的と
したもので、ラムをコネクチングロツドに接続す

円形断面の複数のガイド軸でラムをフレームに支
承させるようにしたものである。 The present invention aims to improve such inconveniences, and uses the shaft cylinder for connecting the ram to the connecting rod as one of the guide shafts.
The ram is supported on the frame by a plurality of guide shafts with circular cross sections.

て作用する。 To explain this with reference to the illustrated embodiment, 1 is a frame, 2 is a crankshaft, 3 is a connecting rod, and 4 is a ram, and the ram 4 has a shaft cylinder 5 with a circular cross section integrally protruding from its upper surface. A ball bolt 7 with a spherical head is attached to the shaft cylinder 5 through a pair of upper and lower ball bearings 6, 6 provided inside the shaft cylinder 5, and the ram 4 is connected to the connecting rod 3 via the ball bolt 7. In addition to being connected, the shaft cylinder 5 is slidably supported in a bearing hole 9' of the frame 1 via an annular bearing 8 attached to its outer periphery, and acts as one of the guide shafts.
更にラム４には軸筒５に平行の軸受孔９を設
け、該軸受孔９は、その内周に取付けられる環状
の軸受１０を介してフレーム１に上下方向に設け
た断面円形のガイド軸１１に摺動自在に支承され
ている。 Further, the ram 4 is provided with a bearing hole 9 parallel to the shaft cylinder 5, and the bearing hole 9 is connected to a guide shaft 11 with a circular cross section provided vertically in the frame 1 via an annular bearing 10 attached to the inner circumference of the bearing hole 9. It is slidably supported on.
クランク軸２が回転すれば、ラム４は、これと
一体の軸筒５が軸受８を介して軸受孔９′に案内
されると共に、該軸筒５と別位置に設けた軸受孔
９が、軸受１０を介してガイド軸１１で案内され
て、正確な上下動を行なう。 When the crankshaft 2 rotates, the shaft cylinder 5 integrated with the ram 4 is guided to the bearing hole 9' via the bearing 8, and the bearing hole 9, which is provided at a different position from the shaft cylinder 5, It is guided by a guide shaft 11 via a bearing 10 to perform accurate vertical movement.

ため、ラム４の傾きを容易に防止することがで
き、したがつてラム４を横方向の振れ及び傾斜を
生じさせることなく高精度に案内できる効果を有
する。 In this way, according to the present invention, since the shaft cylinder 5 for connecting the connecting rod 3 to the ram 4 is used as one of the guide shafts, it has the advantage that the structure is simple, and the shaft cylinder 5 is used as one of the guide shafts. and the guide shaft 11,
Since they have a circular cross section, they can be fitted with the respective annular bearings 9' or 9 with high precision without any play over the entire circumference, and in addition, the shaft cylinder 5 and the guide shaft 11 are spaced apart from each other in the plane direction. Since the ram 4 is supported in a fixed position, it is possible to easily prevent the ram 4 from tilting, and therefore the ram 4 can be guided with high precision without causing lateral deflection or inclination. .
更に、軸筒５、ガイド軸１１、軸受孔９，９′

通の環状の軸受であるから、構造簡単で製作し易
く、精度を出し易い効果を有する。 Furthermore, the shaft cylinder 5, the guide shaft 11, the bearing holes 9, 9'
Both have circular cross sections, and since the bearings 8 and 10 are ordinary annular bearings, they have the advantage of being simple in structure, easy to manufacture, and easy to achieve accuracy.
