Description

本発明は、伸縮式カバーに関する。   The present invention relates to a telescopic cover.

加工時に出る屑が工作機器内に落下して操作および安全に影響を与えるような事態を防止することによって工作機器の使用寿命を大幅に延ばすため、および、加工効率および操作の安全性を向上させるため、様々なカバーが考案されている。よく見掛けられているカバーは伸縮式および固定式である。特に伸縮式カバーは、設置するための空間が少ないだけでなく、ツールヘッドが移動することによって加工を進める工作機器を保護することができる。そのうち、複数の伸縮式カバーを結合させること、すなわち工作機器のツールヘッドの前後に伸縮式カバーを配置し、続いてその左右に伸縮式カバーを配置することによって、多方向移動に対応する方式がある。   In order to greatly extend the service life of machine tools by preventing situations in which debris generated during machining falls into machine tools and affect operations and safety, and to improve machining efficiency and operational safety Therefore, various covers have been devised. The commonly seen covers are telescopic and fixed. In particular, the telescopic cover not only has a small space for installation, but also can protect a machine tool that advances machining by moving the tool head. Among them, there is a method that supports multi-directional movement by combining multiple telescopic covers, that is, by placing telescopic covers on the front and back of the tool head of the machine tool, and then placing the telescopic covers on the left and right sides thereof. is there.

しかしながら、複数の伸縮式カバーを結合させる方式は、設計上の構築および配置が比較的複雑である。さらに、極座標に達するには、水平に移動し続いて垂直に移動するか、垂直に移動し続いて水平に移動する必要があるため、移動進行が単純であり、移動効率が低い。従って改善の余地がある。
本発明は、上述の点に鑑みてなされたものであり、その目的は、移動効率が高い伸縮式カバーを提供することである。 However, the method of combining a plurality of telescopic covers is relatively complicated in design and arrangement. Furthermore, in order to reach polar coordinates, it is necessary to move horizontally and then move vertically, or move vertically and then move horizontally, so that the movement is simple and the movement efficiency is low. Therefore, there is room for improvement.
This invention is made | formed in view of the above-mentioned point, The objective is to provide a telescopic cover with high movement efficiency.

本発明による伸縮式カバーは、大きさが漸減する複数の筐体を大きさの順に重ねることによって構成されている。筐体は、相互に向かい合う一対の板体と、一対の板体のうち一方および他方の中央から他方側および一方側に延びるスリーブ管とを有する。板体は、当該板体が構成する筐体よりも一段階小さい筐体のスリーブ管に被さり、スリーブ管は、当該スリーブ管よりも一段階小さいスリーブ管との間に格納空間を形成している。格納空間は、内部に少なくとも二つのスライドできる弾性復元機構を有する。   The telescopic cover according to the present invention is configured by stacking a plurality of cases whose sizes are gradually reduced in order of size. The housing includes a pair of plate bodies facing each other and a sleeve tube extending from the center of one and the other of the pair of plate bodies to the other side and one side. The plate body covers a sleeve tube of a housing that is one step smaller than the housing that the plate member constitutes, and the sleeve tube forms a storage space between the sleeve tube and the sleeve tube that is one step smaller than the sleeve tube. . The storage space has at least two elastic restoring mechanisms that can slide therein.

上述した構造により、本発明は、最も小さいスリーブ管内にツールヘッド（例えばカッターヘッド、固定工具ヘッド）または可動ユニットを格納し、それらを迅速に移動させると同時に保護効果を果たすことができるだけでなく、単一の移動方式に限らず、移動を多元化することができるため、移動効率がよい。また本発明は、弾性復元機構によってスピーディーな移動が進む際に緩衝および保護機能を果たすことができる。   Due to the structure described above, the present invention not only can store a tool head (eg, cutter head, fixed tool head) or movable unit in the smallest sleeve tube and move them quickly, while at the same time providing a protective effect, The movement efficiency is good because the movement is not limited to a single movement method and the movement can be diversified. In addition, the present invention can perform a buffering and protection function when speedy movement proceeds by the elastic restoring mechanism.

The elastic restoring mechanism 5 includes an elastic unit 50 made of, for example, a spring or an elastic piece. In the present embodiment, the elastic unit 50 is a Z-shaped elastic piece, and at least one end is fixed to the inside of the sleeve tubes 22, 32, 42 in the storage spaces 13, 23, 33 to form the fixed portion 51, and the other end is Although it becomes the floating part 52 which contacts the outer side of the sleeve pipe | tube 12,22,32, it is not restricted to this. In the present invention, the arrangement positions of the fixed portion 51 and the floating portion 52 may be interchanged. Alternatively, any end may be designed to be fixed or floating.

図５から図１０に示すように、本実施形態を使用するとき、筐体４のスリーブ管４２内に可動ユニット、例えばツールヘッド（カッターヘッド、固定工具ヘッド）または別のユニットを格納し、筐体１を平台として固定する。ツールヘッドが移動すると、スリーブ管１２を連動させ、かつスリーブ管２２へ移動させ、続いて相互に繋がるユニットへ順に移動させる。ツールヘッドが単方向または多方向（３６０度）に任意に移動する際、筐体２、３、４はツールヘッドに連動することによって保護機能を果たすことができる。弾性復元機構５は緩衝および保護機能を果たすため、スピーディーな移動を進めることができるだけでなく、衝撃を受けて損壊するような事態を抑制することができる。   As shown in FIGS. 5 to 10, when this embodiment is used, a movable unit such as a tool head (cutter head, fixed tool head) or another unit is stored in the sleeve tube 42 of the casing 4, and the casing is The body 1 is fixed as a flat base. When the tool head is moved, the sleeve tube 12 is interlocked and moved to the sleeve tube 22, and subsequently moved to the units connected to each other. When the tool head is arbitrarily moved in a single direction or in multiple directions (360 degrees), the housings 2, 3, and 4 can perform a protective function by interlocking with the tool head. Since the elastic restoring mechanism 5 functions as a buffer and protects, the elastic restoring mechanism 5 can not only advance the speedy movement but also suppress a situation in which it is damaged due to an impact.
