Description
【考案の詳細な説明】 本考案はチャンネル材のチャック装置に関する。[Detailed explanation of the idea] The present invention relates to a chuck device for channel material.
たとえばエスカレータ用欄干は第１図に示す如きチャン
ネル材１を引張り曲げ加工して製作する。For example, an escalator balustrade is manufactured by stretching and bending a channel material 1 as shown in FIG.
この場合被加工材のチャッキングは、チャンネル材１の
端部を第２図に示すように平板状につぶしてからチャッ
クしている。In this case, the workpiece is chucked after the end of the channel material 1 is flattened into a flat plate as shown in FIG.
したがって、加工後チャック付近を切断してから製品と
しているため、材料の歩留りが悪く、またチャック部分
をつぶす工程が必要であるという欠点があった。Therefore, after processing, the vicinity of the chuck is cut before being manufactured into a product, which has the drawback of poor material yield and the need for a step of crushing the chuck portion.
本考案の目的は上記した従来技術の欠点をなくし、材料
の歩留りを向上させ、かつチャッキングのための前工程
を不要とするチャンネル材のチャック装置を提供するに
ある。An object of the present invention is to provide a channel material chucking device that eliminates the drawbacks of the prior art described above, improves the material yield, and eliminates the need for a pre-process for chucking.
本考案の要点は、チャンネル材の端部を挿入する溝を有
するチャック本体と、その溝に挿入したチャンネル材の
端部の内側に配設する２個１組のこまと、このこまの間
に押し込んでチャンネル材の端部をチャック本体と両こ
まで押圧するくさびと、チャック本体に回動自在に支持
され、且つくさびを押し込んでチャンネル材の端部をチ
ャック本体と両こまで保持する際、上記こまに係合して
チャック本体にチャンネル材の長手方向に固定するつめ
等の固定部材とを備え付けたことを特徴とするものであ
る。The main points of this invention are: a chuck body having a groove into which the end of the channel material is inserted; a set of two pieces placed inside the end of the channel material inserted into the groove; A wedge that is pushed in to press the end of the channel material to both sides of the chuck body, and a wedge that is rotatably supported by the chuck body, and when the wedge is pushed in to hold the end of the channel material to both sides of the chuck body. The present invention is characterized in that it is equipped with a fixing member such as a pawl that engages with the top and fixes the channel material to the chuck body in the longitudinal direction.
以下本考案を第３図および第４図に示す１実施例によっ
て説明する。The present invention will be explained below with reference to an embodiment shown in FIGS. 3 and 4.
第３図は正面図、第４図は側面図である。FIG. 3 is a front view, and FIG. 4 is a side view.
各図において２はチャック本体であって、チャック本体
２にはチャンネル材の端部を挿入するための溝７が穿設
されているとともに、後述する２個１組のこま３を引掛
けて固定するための１組のつめ５がピン６によって回動
自在に取付けられている。In each figure, 2 is a chuck body, and the chuck body 2 has a groove 7 for inserting the end of the channel material, and is fixed by hooking a set of two pieces 3, which will be described later. A set of pawls 5 are rotatably attached by pins 6.
１はチャック本体２の溝７に挿入されるチャンネル材１
の内側に配設される２個１組のこまであって、こま旦の
内側はテーパ状に形成され、また上面には前記つめ５を
引掛ける凹み８が穿設されている。1 is a channel material 1 inserted into the groove 7 of the chuck body 2
A set of two pieces are arranged inside the top, and the inside of the top is formed into a tapered shape, and a recess 8 for hooking the pawl 5 is bored in the upper surface.
４は両こま３の間に押し入れるくさびである。4 is a wedge that is inserted between both tops 3.
このように構成したチャック装置において、まずチャン
ネル材１の端部をチャック本体２の溝７とこま旦の間に
挿入する。In the chuck device constructed in this way, first, the end of the channel material 1 is inserted between the groove 7 of the chuck body 2 and the top.
次にくさび４をこま旦の間に押し込むと、チャンネル材
１はチャック本体２とこま３の間に強い力で押え付けら
れる。Next, when the wedge 4 is pushed between the tops, the channel material 1 is pressed down between the chuck body 2 and the top 3 with a strong force.
つづいてつめ５をこま３にかけてこま３を固定する。Next, put claw 5 on top 3 to fix top 3.
こうすることにより、チャック本体２の下面とくさび４
の上面を平板用チャックではさんでチャンネル材１に長
手方向の力を加えても、チャンネル材１にはチャック本
体２とこま旦との間で摩擦力が働いており、チャンネル
材１はチャックに固定される。By doing this, the lower surface of the chuck body 2 and the wedge 4
Even if a longitudinal force is applied to the channel material 1 by sandwiching the upper surface between the chucks for flat plates, a frictional force is exerted on the channel material 1 between the chuck body 2 and the top, and the channel material 1 is held against the chuck. Fixed.
なお、チャック本体２とこま３のチャンネル材１に接す
る表面に小さな凹凸（例えばヤスリの表面のような形状
）を設けると、摩擦係数が大きくなり、チャンネル材と
チャックとの締結力はより大きくなる。In addition, if small irregularities (for example, a shape like the surface of a file) are provided on the surfaces of the chuck body 2 and the top 3 that are in contact with the channel material 1, the coefficient of friction increases and the fastening force between the channel material and the chuck becomes larger. .
以上説明したように本考案によれば、チャンネル材の端
部を確実にチャッキングすることができ、チャンネル材
の歩留りの向上、およびチャッキングのための前工程の
省酩等の実用的作用効果を奏する。As explained above, according to the present invention, the ends of the channel material can be reliably chucked, and practical effects include improving the yield of the channel material and reducing the amount of alcohol used in the pre-chucking process. play.
