Abstract

(57) [Abstract] [Purpose] The purpose of the present invention is to prevent cutting oil and other liquids from entering a sliding portion of a machine tool as well as cutting oil and dust. [Structure] A telescopic cover that combines a foldable bellows made of cloth and an outer telescopic cover on the sliding part of a machine tool. This structure completely prevents the penetration of cutting oil and other liquids, as well as dust and dust.

Description

[Detailed description of the invention]

Conventionally, a telescopic cover 1 shown in a perspective view of FIG. 1 or a foldable bellows 2 made of cloth shown in a perspective view of FIG. In general, the telescopic cover 1 is formed entirely of a thin iron plate, and is excellent in protecting a sliding portion of a machine tool from dust or the like generated during operation of the machine tool. It also has a function of preventing liquids such as cutting oil from penetrating to some extent, but is incomplete. In general machine tools, it functions well as a protective cover. However, in applications where it is necessary to completely prevent liquid such as cutting oil from entering the inside of the sliding part body of the machine tool, in the case of a telescopic cover, the space between the cover and each step between the cover and the inside of the machine body should be removed. Since intrusion of cutting oil and the like is unavoidable, problems often arise in the design of machine tools. In addition, it caused a failure.

In order to solve the above-mentioned drawbacks, the present invention has conducted intensive studies and has devised a method for completely preventing intrusion of cutting oil and other liquids as well as cutting fluid and dust into a sliding portion of a machine tool. In other words, the cloth folding bellows 2 having at least the top wall 2-1 and the two side walls 2-2 and the end plates 2-3 and 2-4 at both ends in the expansion and contraction directions shown in the perspective view of FIG. As shown in the perspective view of FIG. 1, a plurality of boxes are fitted on each other so as to cover a sliding portion (not shown), and furthermore, the outside of the foldable bellows 2 made of cloth, as shown in the perspective view of FIG. As shown in the perspective view of FIG. 3, a telescopic cover 1 having a structure having 1-1 and two side walls 1-2 and end plates 1-3 and 1-4 at both ends, respectively. Of the telescopic cover 1 and the foldable cover 2 made of cloth, for example, 1-3 and 2-3 of the end plates are on the moving side of the sliding portion of the machine tool. G-1-4 and 2-4 are mounted on the fixed side of the sliding part of the machine tool, and the folding bellows 2 made of cloth and the telescopic cover 1 work together to protect the sliding surface of the machine tool in a stretchable manner. As shown in the perspective view of FIG. 4, a cover made of a plurality of folds is formed on a cover cloth which is made of a tightly-sealed cloth that is impervious to cutting oil and other liquids coated with a thermoplastic resin, as shown in the perspective view of FIG. The top wall 2-1 and the two side walls 2-2 are welded to the valleys of the creased cover material 3 using a plurality of thin and substantially U-shaped plate members 4 made of thermoplastic resin as aggregates. Since it is a foldable bellows made of cloth, it is possible to completely prevent cutting oil and other liquids from entering the sliding part of the machine tool. As described above, the outer telescopic cover prevents Kiriko, dust, and most of the cutting oil and other liquids from entering. A protective cover for the sliding surface of a machine tool by a combination of a telescopic cover and a foldable cover made of cloth, characterized by completely preventing the intrusion of other liquids or, in some cases, minute dust.
