Description
【０００１】[0001]
本考案は、ガイドレールに摺動自在に係合する摺動体を駆動して摺動体に連結 される被駆動物を移動する、摺動体の駆動装置に関する。 The present invention relates to a sliding body driving device that drives a sliding body slidably engaged with a guide rail to move a driven object connected to the sliding body.
【０００２】[0002]
従来、この種の装置として、摺動体にナットを設け、該ナットにガイドレール に沿わせて設けた回転軸を挿通し、該回転軸にナットに螺合するねじ部を形成し て、回転軸の回転により摺動体を駆動するようにしたものは知られている。 Conventionally, as a device of this type, a nut is provided on a sliding body, a rotary shaft provided along a guide rail is inserted into the nut, and a screw portion that is screwed into the nut is formed on the rotary shaft. It is known that the sliding body is driven by the rotation of.
【０００３】[0003]
上記従来装置では、回転軸がガイドレールの両端部の軸受で両端支持されてお り、摺動体の移動ストロークを長く取るためにガイドレールを長くすると、回転 軸の支持スパンが長くなって回転軸の回転振れを生じ易くなり、摺動体を円滑に 駆動できなくなる。 本考案は、以上の点に鑑み、回転軸の振れを抑制して摺動体を円滑に駆動し得 るようにした装置を提供することをその目的としている。 In the above conventional device, the rotary shaft is supported at both ends by the bearings at both ends of the guide rail, and if the guide rail is lengthened to lengthen the moving stroke of the sliding body, the span of the rotary shaft becomes longer, It becomes easy for the sliding body to be driven smoothly and the sliding body cannot be driven smoothly. In view of the above points, an object of the present invention is to provide a device capable of smoothly driving a sliding body by suppressing swing of a rotating shaft.

上記目的を達成すべく、本考案は、ガイドレールに摺動自在に係合する摺動体 に設けたナットにガイドレールに沿わせて設けた回転軸を挿通し、該回転軸にナ ットに螺合するねじ部を形成して、回転軸の回転により摺動体を駆動するように した装置において、回転軸に摺動自在に外挿される１対の支持部材を設け、該両 支持部材を摺動体が間に入るようにガイドレールに摺動自在に係合させると共に 、該両支持部材を所定の間隔を存して連結する連結部材を設けたことを特徴とす る。 In order to achieve the above object, the present invention inserts a rotary shaft provided along a guide rail into a nut provided on a sliding body that slidably engages with the guide rail, and inserts the nut into the rotary shaft. In a device in which a threaded portion is formed to drive a sliding body by rotation of a rotary shaft, a pair of support members slidably inserted into the rotary shaft is provided, and both support members are slidable. It is characterized in that the moving body is slidably engaged with the guide rail so as to be interposed therebetween, and a connecting member for connecting the both supporting members at a predetermined interval is provided.

【作用】 摺動体をガイドレールの一端側から他端側に向けて往動させる場合、摺動体に 対し往動方向側に存する一方の支持部材により回転軸がその中間部分で支持され 、回転軸の支持スパンが短くなって回転軸の回転振れが抑制される。 摺動体が上記一方の支持部材が存する位置まで往動されると、以後摺動体に押 されて一方の支持部材が往動方向に移動し、摺動体に対し復動方向側に存する他 方の支持部材が連結部材を介して一方の支持部材につれ動きし、摺動体がガイド レールの他端に到達したとき他方の支持部材が回転軸の中間部分に位置し、ガイ ドレールの他端側から一端側への復動に際し、回転軸の中間部分が他方の支持部 材で支持されて、往動時と同様に回転軸の回転振れが抑制される。When the sliding body is moved forward from one end side to the other end side of the guide rail, the rotating shaft is supported at the intermediate portion by one supporting member existing on the moving direction side with respect to the sliding body. The supporting span is shortened and rotational runout of the rotating shaft is suppressed. When the sliding body is moved forward to the position where the one support member is present, it is pushed by the sliding body and one support member is moved in the forward movement direction. When the supporting member moves along with one supporting member via the connecting member, and the sliding body reaches the other end of the guide rail, the other supporting member is located at the middle part of the rotating shaft, and one end from the other end of the guide rail. When returning to the side, the intermediate portion of the rotary shaft is supported by the other support member, and the rotational runout of the rotary shaft is suppressed as in the forward movement.
