Description
【０００１】[0001]
この考案は製図機械に関するものであり、特に、レール形自在定規や平行定規 等のキャリッジの緩衝装置に関するものである。 The present invention relates to a drafting machine, and more particularly to a shock absorbing device for a carriage such as a rail type universal ruler or a parallel ruler.
【０００２】[0002]
例えば、レール形自在定規は、図板の上縁部に固定されるＸレールにＸキャリ ッジが係合され、ＸキャリッジにてＹレールが支持されている。ＹレールにはＹ キャリッジが係合され、Ｙキャリッジに装着した製図ヘッドにスケールが取付け られる。製図ヘッドはＸキャリッジ並びにＹキャリッジの可動範囲内において図 板上をＸ−Ｙ方向へ自在に移動させることができる。そして、Ｙレールや製図ヘ ッドを支持するＸキャリッジには、走行方向の前後両端部位にゴム片等の緩衝材 を設け、ＸキャリッジがＸレールの両端に装着した端面カバー等のキャリッジス トッパー部材に衝突する際の衝撃を吸収させている。 For example, in a rail-type universal ruler, an X carriage is engaged with an X rail fixed to the upper edge of the drawing board, and the Y rail is supported by an X carriage. The Y carriage is engaged with the Y rail, and the scale is attached to the drafting head mounted on the Y carriage. The drafting head can be freely moved on the drawing board in the XY directions within the movable range of the X carriage and the Y carriage. The X carriage supporting the Y rail and the drawing head is provided with cushioning material such as rubber pieces at both front and rear ends in the traveling direction, and the carriage stopper such as an end face cover attached to both ends of the X rail by the X carriage. It absorbs the impact when it collides with a member.
【０００３】[0003]
従来のキャリッジはゴム片等の緩衝材を装着して、キャリッジがキャリッジス トッパーへ衝突する際の衝撃を吸収させているが、Ｙレール等の重量物を搭載し たキャリッジの慣性が大であるため、衝撃吸収性能が不足し、且つ、反撥力も強 く操作感覚が良好ではない。また、衝撃はキャリッジ及びキャリッジに連結され た各部材の精度に悪影響を及ぼし、耐久性低下の原因にもなる。 The conventional carriage is equipped with a cushioning material such as a rubber piece to absorb the impact when the carriage collides with the carriage stopper, but the inertia of the carriage carrying a heavy object such as a Y rail is large. Therefore, the shock absorbing performance is insufficient, the repulsive force is strong, and the operation feeling is not good. In addition, the impact adversely affects the accuracy of the carriage and the members connected to the carriage, and also causes deterioration of durability.
【０００４】 そこで、キャリッジとキャリッジストッパーとの衝突時の衝撃を軽減し、操作 感覚を改善するとともに、耐久性低下の虞れを解消するために解決すべき技術的 課題が生じてくるのであり、本考案は上記課題を解決することを目的とする。Therefore, there are technical problems to be solved in order to reduce the impact at the time of collision between the carriage and the carriage stopper, improve the operation feeling, and eliminate the fear of deterioration of durability. The present invention aims to solve the above problems.
【０００５】[0005]
この考案は、上記課題を解決するために提案するものであり、図板の縁部に固 定したレールにキャリッジの転動輪を係合し、前記レールの両端部位に端面カバ ー等のキャリッジストッパーを設けたレール式製図機械に於て、前記キャリッジ に板バネの基端部を固定し、該板バネの先端部を前記転動輪の前記キャリッジス トッパーへ対向する側へ配設し、前記先端部にゴム等の緩衝材を装着し、該緩衝 材を前記転動輪の外周面に対峙させた製図機械に於けるキャリッジの緩衝装置を 提供するものである。 This invention is proposed in order to solve the above-mentioned problems. A rolling wheel of a carriage is engaged with a rail fixed to an edge portion of a drawing board, and a carriage stopper such as an end cover is provided at both end portions of the rail. In a rail type drafting machine provided with, a base end portion of a leaf spring is fixed to the carriage, and a tip end portion of the leaf spring is arranged on a side of the rolling wheel facing the carriage stopper. Provided is a cushioning device for a carriage in a drafting machine in which a cushioning material such as rubber is attached to a portion, and the cushioning material faces the outer peripheral surface of the rolling wheel.
【０００６】[0006]
キャリッジに取付けられた板バネの先端部は、転動輪のキャリッジストッパー へ対向する側に配置されて転動輪の外周面に対峙している。キャリッジをレール の端部へ向けて走行させると、転動輪がキャリッジストッパーに衝突する以前に 板バネの先端部がキャリッジストッパーに当接し、キャリッジは板バネの弾性に よって減速される。板バネの先端部にはゴム等の緩衝材が装着されており、キャ リッジがキャリッジストッパー側へ更に走行することにより、前記緩衝材がキャ リッジストッパーと転動輪とによって挟圧される。転動輪は緩衝材との摩擦によ って回転を制動され、キャリッジが停止されるとともに緩衝材によって衝突時の 衝撃が緩和される。 The tip of the leaf spring attached to the carriage is arranged on the side of the rolling wheel that faces the carriage stopper and faces the outer peripheral surface of the rolling wheel. When the carriage is run toward the end of the rail, the tip of the leaf spring contacts the carriage stopper before the rolling wheels collide with the carriage stopper, and the carriage is decelerated by the elasticity of the leaf spring. A cushioning material such as rubber is attached to the tip end of the leaf spring, and the cushioning material is pinched by the carriage stopper and the rolling wheels as the carriage further travels toward the carriage stopper. Rotation of the rolling wheels is braked by friction with the cushioning material, the carriage is stopped, and the shock absorbing material is cushioned by the cushioning material.

以下、この考案の一実施例を図に従って詳述する。図１はレール式自在定規１ を示し、図板２の上縁部にＸレール３が固定され、Ｘレール３にＸキャリッジ４ の転動輪５，５，６，６を係合してＸキャリッジ４を吊下している。Ｘレール３ の左右両端部には端面カバー７，７が固着され、Ｘキャリッジ４のストッパーと している。Ｘキャリッジ４にはＹレール８のブラケット８ａが係着され、Ｙレー ル８に係合するＹキャリッジ９のヒンジ部９ａに製図ヘッド１０が取付けられて いる。 An embodiment of the present invention will be described in detail below with reference to the drawings. FIG. 1 shows a rail-type universal ruler 1 in which an X rail 3 is fixed to the upper edge of a drawing board 2, and rolling wheels 5, 5, 6, 6 of an X carriage 4 are engaged with the X rail 3 to make the X carriage 4 is hanging. End covers 7, 7 are fixed to the left and right ends of the X rail 3 and serve as stoppers for the X carriage 4. A bracket 8a of a Y rail 8 is attached to the X carriage 4, and a drawing head 10 is attached to a hinge portion 9a of a Y carriage 9 that engages with the Y rail 8.
【０００８】 図２は、Ｘキャリッジ４を示し、ダイキャスト製フレーム１１の上面には長手 方向へ離隔する二対の水平転動輪５，５，６，６が平行に配設され、Ｘキャリッ ジ４の進行方向に沿って片側に２個とその反対側に１個の垂直転動輪１２，１２ ，１３が設けられている。 Ｘレール３に吊下されるＸキャリッジ４は、３個の垂直転動輪１２，１２，１ ３によって荷重を支持し、水平転動輪５，５，６，６により進行方向に対する左 右のヨーイングを規制して、直進精度を確保している。また、進行方向に対して 前後に配置された一対の水平転動輪６，６の支持台１４，１４には夫々本考案の 緩衝装置である板バネ１５，１５の基端部を固着し、先端部は折曲されて夫々水 平転動輪６，６の外周面近傍、且つＸレール３の端面カバー７，７に対向する位 置に延長されている。FIG. 2 shows an X carriage 4, in which two pairs of horizontal rolling wheels 5, 5, 6, 6 which are spaced apart in the longitudinal direction are arranged in parallel on the upper surface of a die-cast frame 11, and an X carriage is provided. Two vertical rolling wheels 12, 12 and 13 are provided on one side and one vertical rolling wheel 12, 13 on the opposite side along the traveling direction of No. 4. The X carriage 4 suspended on the X rail 3 supports the load by the three vertical rolling wheels 12, 12, 13 and the left and right yawing with respect to the traveling direction by the horizontal rolling wheels 5, 5, 6, 6. It regulates and secures straightness. Further, the base ends of the leaf springs 15 and 15 which are the shock absorbers of the present invention are fixed to the support bases 14 and 14 of the pair of horizontal rolling wheels 6 and 6 arranged in the front-rear direction with respect to the traveling direction, respectively. The parts are bent and extended near the outer peripheral surfaces of the horizontal rolling wheels 6 and 6, respectively, and at positions facing the end surface covers 7 of the X rail 3.
【０００９】 板バネ１５，１５の先端部の水平転動輪６，６に対峙する面にはゴム片１６， １６が固着され、板バネ１５，１５の先端部を水平転動輪６，６の方向へ押圧し たときにゴム片１６，１６が水平転動輪６，６の外周面に当接するように形成し てある。 次に、図３に従って緩衝装置の作用を説明する。同図（ａ）においてＸキャリ ッジ４はＸレール３の中間部位にあり、板バネ１５は無負加状態にある。Ｘキャ リッジ４を左方向へ走行させて、同図（ｂ）に示すように板バネ１５がＸレール ３の左端面カバー７に接すると、板バネ１５は端面カバー７に押圧されて撓み、 且つ板バネ１５の反撥力によってＸキャリッジ４の移動速度が減速される。そし て、同図（ｃ）に示すように板バネ１５が水平転動輪６と端面カバー７とによっ て挟圧され、板バネ１５に固着したゴム片１６に水平転動輪６の外周面が接触す ると、水平転動輪６は板バネ１５のゴム片１６との摩擦によって回転を制動され るとともに、ゴム片１６の弾力によってＸキャリッジ４の停止時の衝撃を吸収す る。Rubber pieces 16 and 16 are fixed to the surfaces of the leaf springs 15 and 15 facing the horizontal rolling wheels 6 and 6, and the tip ends of the leaf springs 15 and 15 are directed in the direction of the horizontal rolling wheels 6 and 6. The rubber pieces 16 and 16 are formed so as to contact the outer peripheral surfaces of the horizontal rolling wheels 6 and 6 when pressed to. Next, the operation of the shock absorber will be described with reference to FIG. In FIG. 3A, the X carriage 4 is located at an intermediate portion of the X rail 3 and the leaf spring 15 is in a non-loading state. When the X carriage 4 is moved to the left and the leaf spring 15 comes into contact with the left end face cover 7 of the X rail 3 as shown in FIG. 2B, the leaf spring 15 is pressed by the end face cover 7 and bends, Moreover, the repulsive force of the leaf spring 15 reduces the moving speed of the X carriage 4. Then, as shown in FIG. 3C, the leaf spring 15 is pinched by the horizontal rolling wheel 6 and the end face cover 7, and the outer peripheral surface of the horizontal rolling wheel 6 is attached to the rubber piece 16 fixed to the leaf spring 15. Upon contact, the horizontal rolling wheel 6 is braked in rotation by friction with the rubber piece 16 of the leaf spring 15, and the elastic force of the rubber piece 16 absorbs the shock when the X carriage 4 is stopped.
【００１０】 このように、Ｘキャリッジ４の走行速度を先ず板バネ１５によって減速した後 に、板バネ１５に装着したゴム片１６によって転動輪６を制動するとともに、Ｘ キャリッジ４と端面カバー７との衝突による衝撃を吸収するので、Ｘキャリッジ ４は円滑に停止され反撥も軽減される。 尚、本考案は上記一実施例に設定されるべきものではなく、板バネ１５の取付 位置や形状等は種々の改変ができ、この考案がそれらの改変されたものに及ぶこ とは当然である。As described above, after the traveling speed of the X carriage 4 is first reduced by the leaf spring 15, the rolling wheel 6 is braked by the rubber piece 16 attached to the leaf spring 15, and the X carriage 4 and the end surface cover 7 are Since the impact due to the collision is absorbed, the X carriage 4 is smoothly stopped and the repulsion is also reduced. It should be noted that the present invention should not be set to the above-described embodiment, and the mounting position and shape of the leaf spring 15 can be modified in various ways, and it goes without saying that the invention extends to these modified ones. is there.
【００１１】[0011]
この考案は、上記一実施例において詳述したように、製図機械のキャリッジが レールの端板に衝突する際にキャリッジの走行速度をバネによって減速させるの で従来のゴム等の弾性材によって緩衝するものに比較して衝突の直前から円滑に 減速される。また、バネに設けたゴム片等の緩衝材が、減速されたキャリッジの 転動輪に接触して転動輪を制動し、キャリッジを停止させるとともに転動輪とキ ャリッジストッパーとの衝突の衝撃を吸収するので、キャリッジの停止時の衝撃 及び反動が著しく軽減される。従って、転動輪及びキャリッジに連結された各部 材への衝撃が緩和されることにより部材精度への悪影響を低減でき、耐久性の向 上に寄与できる。 As described in detail in the above one embodiment, this invention uses a conventional elastic material such as rubber to cushion the traveling speed of the carriage by a spring when the carriage of the drafting machine collides with the end plate of the rail. Compared to the ones, the speed is slowed down just before the collision. In addition, a cushioning material such as a rubber piece provided on the spring comes into contact with the rolling wheels of the decelerated carriage to brake the rolling wheels, stop the carriage, and absorb the impact of collision between the rolling wheels and the carriage stopper. Therefore, the impact and the recoil when the carriage is stopped are significantly reduced. Therefore, since the impact on each member connected to the rolling wheels and the carriage is mitigated, the adverse effect on the member accuracy can be reduced, and the durability can be improved.
