Description

[Detailed description of the invention]

The present invention relates to a shock-absorbing cushion body for extending / sliding a sliding surface protection cover for protecting the sliding surface of an industrial machine, in particular, a machine tool from cutting chips, dust, cutting oil and the like. It is about.

The present invention relates to a method of forming a plurality of thin iron plates formed by bending one cut thin iron plate into one top wall, two side walls, and one partially provided shoulder wall. At least two protective covers for a sliding surface protective cover of a machine tool comprising a protective cover, wherein a second protective cover is sequentially mounted on a first protective cover and a third protective cover is mounted on a second protective cover. Are sequentially combined in a skewed shape, and are slidably extended and contracted.In the sliding surface protection cover of the machine tool, the bending process is performed to partially or entirely cover the shoulder wall provided in the width direction. On the other hand, the cushion material portion of the metal plate material with a cushion material, in which a cushion material made of a rubber-like elastic body is fastened in the longitudinal direction on one side in the width direction of one side in the width direction of the metal plate material, Protruding from the horizontal plane of the ceiling The present invention relates to a cushion body for reciprocating sliding of a protective cover, characterized in that the cushion body is fixed as described above. This embodiment will be described below with reference to the drawings.

FIGS. 1, 2 and 3 are sectional views of the protective cover of the present invention. FIG. 1 shows the most contracted state, FIG. 2 shows the most expanded state, and FIG. 3 shows the state in which the most contracted state or the most extended state is being extended or contracted. FIG. 4 shows a cross-sectional view of a typical example of a metal plate material with a cushion material (hereinafter, referred to as a cushion plate material). FIG. 5 shows a sectional view of the wiper for reference.

In FIG. 1, a second cover 1 b and a third cover 1 c are sequentially mounted on the first cover 1 a in a skewed manner, and the first cover 1 a is provided with a back wall 5 and the second cover 1 b, Back walls 2b and 2c formed by bending are respectively provided on the second cover 1c, and cushions are provided on the respective back walls of the second and third covers except for the first cover 1a located on one outside. The plate members 3b and 3c are mounted such that the cushion members protrude beyond the top wall surface from the corners of the back wall as shown in the figure. In addition, the wipers 4a and 4b are fixed to ends of the respective covers facing the back wall except for the third cover located on the other outer side in the drawing. The back wall of the first cover 1a is bent in the opposite direction to the second and third covers to form a mounting portion 5 for attachment to the machine body, and a stopper 6 having a necessary stopper function is provided. On the other hand, the mounting body 7 with the machine main body provided on the third cover is fixed.

Next, expansion and contraction by the action of wipers 4 a and 4 b having a stopper function, which are opposed to the cushion plates 3 b and 3 c provided on the back walls 2 b and 2 c and the stopper 6 provided on the first cover 1 a, respectively. FIG. 2 shows the operation in the most extended state, and FIG. 3 shows the state in the course of extending or contracting from the most contracted state or the most extended state.

Next, in order to operate the cover of FIG. 1 from the most contracted state to the most extended state as shown in FIG. 2, a detailed view is omitted, but the first cover 1a is moved in FIG. When the third cover 1c is used as a fixed cover and the third cover 1c is extended in the direction of the arrow, the wiper 4 has a stopper function of forming the cushion plate members 3b, 3c appropriately protruding from the top wall surface and the wipers 4a, 4b opposed thereto. It operates by the action between the core metals 4a 'and 4b'. That is, the wiper mandrel 4a 'facing the cushion plate 3b and the wiper mandrel 4b' facing the cushion plate 3c are connected to each other to extend the cover. Also, when the cover is contracted in the direction of the arrow shown in FIG. 3 from the most extended state in FIG. 2, sliding is performed between the covers having the least resistance due to the mutual sliding frictional resistance between the first, second, and third covers. In the case of FIG. 3, the first cover and the second cover slide and shrink sequentially. That is, although the detailed explanation is omitted, in the figure, the cover 1a moves in the direction of the arrow, and the stopper 6 attached to the first cover and the cushion plate 3b attached to the back wall 2b of the second cover. The cover 1c contacts and moves with the cushion portion 3b ', until the back wall 2b of the second cover comes into contact with the cushion 3c' portion of the cushion plate 3c attached to the back wall 2c of the third cover. It moves, resulting in the most contracted state shown in FIG.

In the above-described expansion and contraction operation by the related operation between the shoulder wall, the cushion plate member, and the wiper with a stopper function, the cushion members 3b ′ and 3c ′ made of rubber-like elastic members provided on the cushion plate member come into contact with each other. A protective cover that has a cushioning material for expansion and contraction on the shoulder wall and has a metal plate fastened to it, which has the function of absorbing the shocks that occur when it occurs.
