伸縮動を可能にしたテレスコピックカバーに関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telescopic cover that covers and protects a guide surface of a machine tool, a coordinate measuring machine, or the like, and enables expansion and contraction of the machine, especially in response to an increase in size and an increase in speed. About Telescopic Covers.

Description of the Related Art Conventionally, in order to prevent dust and the like from entering a guide surface of a machine, a method has been adopted in which a plurality of large and small cover bodies are covered and protected by telescopic covers which are telescopic. There is.

ものである。This type of cover has one end attached to a fixed end of a guide surface such as a bed, and the other end attached to a movable body such as a table main body so that the table main body on the bed surface is attached. It follows the movement to expand and contract the cover,
In the contraction state, that is, in the extension of the cover from the state where the small cover body is sequentially inserted into the large cover body, first, the cover body attached to the table body is pulled out, and the cover body end is pulled out. The engaging part provided on the part engages with the overlapping end of the cover body and pulls it out, and then successively pulls out the next cover body that overlaps the pulled out cover body in the same manner and extends it. To reduce the cover from the state, the cover is sequentially retracted from the table body side in the reverse order of the above to reduce the cover.

に悪影響を与える。By the way, with the recent increase in size of machines and high-speed work, the size of the telescopic cover itself has increased, and the engaging portions provided at the end portions of the respective cover bodies which overlap with such a large cover as described above. If a structure is adopted in which the two are engaged and expanded and contracted sequentially, the abutting / engaging of the engaging parts between the cover bodies is shocked, and this is also transmitted to the table body, and the processing accuracy of the product is improved. And adversely affect the measurement accuracy.

ば、実開昭５１−７５６８６号公報参照）In order to solve the above problems, therefore, a structure has been proposed in which a plurality of large and small cover bodies are connected by a pantograph type link mechanism. (See, for example, Japanese Utility Model Laid-Open No. 51-75686).

ることになる。However, in the conventional telescopic cover equipped with the pantograph type link mechanism, since the cover bodies simultaneously start to operate via the link mechanism, the impact between the cover bodies is increased. However, considering the followability to the high-speed and agile operation of the table body when the machine becomes larger and faster, the weight of the cover is required, but the conventional link lengths are equal. In the cover equipped with the link mechanism of, the movement amount (movement amount) between the cover bodies becomes uniform regardless of the size of the cover body, and the size of the end cover body having the smallest movement amount is large. Since it is set according to the
At the time of maximum extension, between the other cover bodies excluding the end cover body that is the smallest, the cover portions stop midway of extension and the overlap length becomes long, and this portion gives extra weight as a play portion.

構を有して構造が複雑になっている。Further, the load applied to each cover body in which a plurality of large and small cover bodies are nested is greater as the inner cover body is stronger, and the strength of the link mechanism is such that the operation of the cover body on which the largest load is exerted. Since the setting is done with consideration, the link mechanism has more strength than necessary when operating the other cover bodies except the cover body that receives the largest load. Is giving a good weight. Further, the structure is complicated by having a link mechanism on each side of the moving body.

Another object is to provide an inexpensive telescopic cover.

とを特徴とするテレスコピックカバーにある。The object of the first invention of the present invention to achieve the above object is to provide a movable body which moves along a guide surface of a machine and an end portion of the guide surface. In between, multiple large and small cover bodies are nested, and each cover body is elastically connected by a pantograph type link mechanism,
In telescopic cover for covering the guide surface, the
The plurality of cover bodies are stacked inward as they are close to the moving body.
Neighboring, and the length in the expansion / contraction direction is close to the moving body.
And the link mechanism reduces its link length to
The telescopic cover is characterized in that the length is gradually increased from the side of the inner cover body that is close to the moving body in correspondence with the length of the cover body. The gist of the second invention is to provide a machine guide. Between the movable body that moves along the surface and both ends of the guide surface, a plurality of large and small cover bodies are nested, and each cover body is telescopically connected by a pantograph type link mechanism, and the guide surface is In the telescopic cover to cover, each cover body of one side of the moving body is telescopically linked by a pantograph type link mechanism, and the telescopic cover on the other side of the moving body is formed of the moving body and the guide surface. An intermediate cover body except for the end cover bodies that are respectively close to the end portions is connected to a corresponding intermediate cover body on the link mechanism connecting side via a connecting rod. In the nanoscopic cover.

軽量化が図られる。[0013] Each cover body is located inside as it is closer to the moving body.
And the length in the expansion / contraction direction is close to the moving body.
The shorter the link mechanism, the shorter the link mechanism
Inner side close to the moving body according to the length of the cover body
The cover body is gradually lengthened from the side, and each cover body operates in proportion to the link length, so the movement amount between each cover body is adapted to the size of each cover body,
The weight of the cover itself can be reduced by reducing the play part from the actual work.

図られる。Further, a larger load is applied to the inner cover body from the side of the cover bodies which are stacked on top of each other, but since the inner cover body has a shorter link length of the link mechanism, each cover body is connected via the link mechanism. Since the operating force applied to the robot operates in a ratioally distributed manner, each link that constitutes the link mechanism has a required strength and can be reduced in weight.
【００１５】従って、カバー自体の軽量化と、リンク機

The cover operates in the same manner without difficulty.
