Description

The present invention relates to a telescopic cover that is attached to an industrial device so as to cover a moving mechanism such as a spindle head, a piston, a cylinder, etc. of the industrial device, and a plurality of pantographs are attached to the telescopic cover to move the industrial device. The present invention relates to a telescopic cover that can be slid according to the movement of the lens.

  Conventionally, if the moving mechanism such as the spindle head, piston, cylinder, etc. of industrial equipment is exposed, there is a problem that the surroundings are contaminated by the scattering of oil, etc., and there is a risk of pinching the limbs and clothes of workers. The moving mechanism of industrial equipment is covered with a telescopic cover formed by slidably laminating a plurality of thin plate-shaped part covers. In this case, in order to enhance the sliding of the telescopic cover, a plurality of telescopic covers are provided on the telescopic cover. A single pantograph was attached, and the telescopic cover was slid together with the pantograph in accordance with the movement of the movement mechanism of the industrial equipment.

  For example, as shown in FIG. 1, a telescopic cover 1 disclosed in JP-A-8-155780 has a plurality of rectangular thin plate-like part covers 2a, 2b, 2c, 2d, 2e, 2f, and 2g that are slidably laminated. In this telescopic cover 1, two rows of pantographs 3a and 3b are attached horizontally at intervals.

JP-A-8-155780

  In order to attach the pantographs 3a and 3b to the telescopic cover 1, for example, as shown in FIG. 2, an attachment shaft 7 rotatably inserted into each intersection portion 5 of the connecting bar 4 of the pantographs 3a and 3b is formed in each thin plate shape. The parts cover 2a, 2b, 2c, 2d, 2f, and 2g are rotatably inserted into the bearings, the industrial device sliding mechanism 9 is attached to the parts cover 2a, and the fixing mechanism 10 is attached to the parts cover 2g. Yes.

  Moreover, as shown in FIG. 3, the telescopic cover 1 to which the pantographs 3a and 3b are attached uses two sets of slidably laminated plural sheet-like part covers 2a to 2g. The telescopic covers 1 are arranged facing each other and loaded into the frame body 7 and the longest protruding portion 11 is provided among the partial covers 2 of the two telescopic covers 1 of the two telescopic types. In some cases, a sliding mechanism 9 for industrial equipment is attached in the space 12 formed by the partial cover 2a.

  And when the sliding mechanism 9 of industrial equipment slides in one direction, both sides of the part covers 2a to 2g of the telescopic cover 1 slide along the inner surface of the frame body 8 and extend at the same time. When the sliding mechanism 9 of the industrial equipment slides in the other direction, both sides of the part covers 2a to 2g of the telescopic cover 1 of the telescopic cover 1 are framed 8 At the same time, the pantographs 3a and 3b are also slid and contracted along the inner surface, and this operation is repeated thereafter. Then, the sliding mechanism 9 of the industrial equipment is moved to an arbitrary range within a predetermined distance. When moving back and forth to the position, the telescopic cover 1 covers the periphery of the sliding mechanism 9 of the industrial equipment.

  However, in the telescopic cover 1, the parts cover 2a to 2g and the pantographs 3a and 3b have their own weights, so that the entire telescopic cover 1 is bent in a dish shape, and the parts covers 2a to 2g and the pantographs 3a and 3b are slidable. Since it is not uniform and the frictional resistance is locally increased, the mobility and linkage of the entire telescopic cover become unstable, causing failure, occurrence of metal noise, and other troubles.

In the present invention, a plurality of pantographs are attached to a telescopic cover formed by slidably laminating a plurality of thin plate-like parts covers, and the parts cover and the pantograph are integrated with the movement mechanism of the industrial equipment. By keeping the parts cover and pantograph flat as a whole and making the frictional resistance and slidability of the parts cover and pantograph uniform throughout, the telescopic cover can be reciprocated safely and reliably. In particular, the object is to operate smoothly, and in particular to provide a large telescopic cover that can appropriately cope with the high-speed and complicated movement of recent industrial equipment.

  The present invention relates to a telescopic cover provided with a plurality of pantographs, and a plurality of pantographs are attached to a telescopic cover formed by slidably laminating a plurality of thin plate-shaped part covers to move industrial equipment. As the telescopic cover slides integrally with the pantograph according to the movement of the mechanism, one pantograph is horizontally attached to the telescopic cover to form a horizontal pantograph, and the other telescopic cover is vertically attached to the telescopic cover. By forming a pantograph, the telescopic cover is maintained in a flat state as a whole.

  The present invention also provides a telescopic cover provided with a plurality of pantographs as described above, wherein an L-shaped support plate is fixed to a rising plate provided on the telescopic cover, and a vertical pantograph is attached to the support plate. It is characterized in that it is attached to the telescopic cover more reliably and stably.

  By providing a horizontal pantograph and a vertical pantograph on the telescopic cover, the present invention eliminates the deflection of the telescopic cover caused by the weight of the parts cover and the pantograph, maintains the entire telescopic cover in a flat state, By eliminating the local increase in frictional resistance of the pantograph, making the slidability uniform, and stabilizing the overall mobility and interlocking of the telescopic cover, it is possible to break down the telescopic cover, generate metal noise, and other problems. There is an advantage to prevent.

  An example of a telescopic cover provided with a pantograph according to the present invention will be described with respect to an industrial machine. As shown in FIG. 4, a telescopic cover 1 is made of a plurality of rectangular thin metal parts such as stainless steel parts covers 2a and 2b. 2c, 2d, 2e, and 2f are slidably laminated, and a plurality of pantographs are attached to the telescopic cover 1 as in the prior art, and one pantograph is placed horizontally with respect to the telescopic cover 1 The horizontal pantograph 3h is not changed but is different in that the other telescopic cover is attached perpendicularly to the telescopic cover 1 to form the vertical pantograph 3p.

  Similarly to the conventional case shown in FIG. 2, the horizontal pantograph 3h is provided with the mounting shafts 7 rotatably inserted in the intersections 5 of the connecting bars 4 on the partial covers 2a to 2f. Each pin holder is rotatably inserted.

For the vertical pantograph 3p, as shown in FIGS. 4 and 5, an L-shaped support plate 14 is fixed to a rising plate 13 provided at the tip of the part covers 2a to 2f, and each pin provided on the support plate 14 is fixed. The mounting shafts 7 that are rotatably inserted into the intersections 5 of the connecting bars 4 are inserted into the receivers every other rotation, but without the rising plates 13 provided in the parts covers 2a to 2f. The L-shaped support plate 14 may be directly fixed to the parts covers 2a to 2f, and the sliding mechanism of the industrial equipment is provided on the parts cover 2a of the telescopic cover 1 provided with the horizontal pantograph 3h and the vertical pantograph 3p. 9 is attached, and the fixing mechanism 10 is attached to the parts cover 2f.

  When the sliding mechanism 9 of the industrial equipment slides in one direction, the parts covers 2a to 2f of the telescopic cover 1 slide and extend, and at the same time, the horizontal pantograph 3h and the vertical pantograph 3p slide and extend, When the sliding mechanism 9 of the industrial equipment slides in the other direction, the part covers 2a to 2f of the telescopic cover 1 slide and contract simultaneously, and the horizontal pantograph 3h and the vertical pantograph 3p also slide. This operation is repeated after that, but at this time, the vertical pantograph 3p prevents the telescopic cover from being bent due to the weight of the parts covers 2a to 2f and the horizontal pantograph 3h, and maintains the entire telescopic cover in a flat state. Then, there is no increase in local frictional resistance between the parts covers 2a to 2f and the horizontal pantograph 3h. , In the uniform sliding property, safety linkage with the overall movement of the telescopic cover, certainly, is smoothly.

  Stainless steel may be used as the material of the metal thin part cover 2 of the telescopic cover 1, but a soft ferrite phase, a hard martensite phase, and a fine mixed structure mainly composed of 17% Cr-2% Ni. The physical strength of the parts cover 2 may be further enhanced by using a high-strength multilayered stainless steel having

  The number of the metal thin parts cover 2 of the telescopic cover 1 may be 3 to 30, and the width of the parts cover 2 is suitably 5 to 200 cm and the length is 5 to 50 cm. Further, the shape of the parts cover 2 May be a square other than the rectangle described above.

  As the material of the horizontal pantograph 3h and the vertical pantograph 3p, stainless steel may be used. However, a high ferrite having a soft ferrite phase, a hard martensite phase, and a fine mixed structure mainly composed of 17% Cr-2% Ni. The physical strength of the pantograph 7 may be increased by using high-strength multilayered stainless steel.

  Stainless steel may be used as the material of the mounting shaft 7 of the horizontal pantograph 3h and the vertical pantograph 3p, but when stainless steel subjected to nitriding nitriding treatment is used, the surface of the mounting shaft 7 is hardened. Therefore, it is extremely excellent in slidability and physical strength, and even if excessive force is applied to the parts covers 2a to 2f and the horizontal pantograph 3h, the surface of the mounting shaft 7 is not damaged and the play does not occur. And since the mounting shaft 7 is not cured to the inside, it is flexible, the shaft is not bent or bent, and the stretchability and slidability of the horizontal pantograph 3h and the vertical pantograph 3p are improved. Operate stably and smoothly over a long period of time.

The horizontal pantograph 3h and the vertical pantograph 3p are attached to the telescopic cover 1 formed as described above at intervals in two rows, but the horizontal pantograph 3h and the vertical pantograph 3p are not limited to two rows, and the telescopic cover 1 is large. Alternatively, in the case where stable slidability is required, 4 to 8 rows may be attached, and the optimum distance between the horizontal pantograph 3h and the vertical pantograph 3p is 3 to 50 cm. A known structure used may be used.

  The present invention can be used as a telescopic cover that covers the moving mechanism of spindle heads, pistons, cylinders, and the like of industrial equipment. Especially in recent telescopic covers, the weight of the parts cover and the pantograph becomes heavy. In this case, it can be used as an optimal telescopic cover.
