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 of the spindle head, piston, cylinder, etc. of industrial equipment is exposed naked, there is a risk that the oil will scatter and the surroundings will be contaminated, and there is a risk of pinching workers' hands and feet and clothes. In addition, the telescopic cover formed by slidably laminating a plurality of thin plate-like parts covers covers the moving mechanism of industrial equipment. In this case, in order to increase the sliding of the telescopic cover, A plurality of pantographs were attached, and the telescopic cover was slid together with the pantographs according to the movement of the movement mechanism of the industrial equipment.

  For example, as shown in FIG. 1, a telescopic cover disclosed in Japanese Patent Application Laid-Open No. 8-155780 has a telescopic cover 1 having a plurality of rectangular thin part covers 2a, 2b, 2c having the same width and different lengths. 2d, 2e, 2f, and 2g are slidably laminated, and two rows of pantographs 3a and 3b are attached to the telescopic cover 1 in parallel with a gap therebetween.

JP-A-8-155780

  In order to attach the pantographs 3a and 3b to the telescopic cover 1, for example, as shown in FIG. The parts covers 2a, 2b, 2c, 2d, 2f, and 2g are inserted into the bearings 7 in a rotatable manner.

  As shown in FIG. 3, the entire telescopic cover 1 to which the pantographs 3a and 3b are attached is loaded into a frame 8, and a sliding mechanism 9 for industrial equipment is attached to the parts cover 2a of the telescopic cover 1, and the parts cover 2g The fixing mechanism 10 is attached to the head.

  When the sliding mechanism 9 of the industrial equipment slides in one direction, both sides of the parts cover 2a, 2b, 2c, 2d, 2e, 2f, and 2g of the telescopic cover 1 of the telescopic cover 1 When the pantographs 3a and 3b slide and extend at the same time as sliding along the inner surface, and the sliding mechanism 9 of the industrial equipment slides in the other direction, the telescopic cover 1 of the telescopic cover The side covers of the parts covers 2a, 2b, 2c, 2d, 2e, 2f, and 2g slide along the inner surface of the frame 8 and shrink, and the pantographs 3a and 3b also slide and shrink. When the industrial mechanism sliding mechanism 9 is reciprocated to an arbitrary position within a predetermined distance range, the telescopic cover 1 surrounds the industrial equipment sliding mechanism 9. And in such a manner as to cover Te.

  However, as shown in FIG. 2, the mounting shaft 6 fitted into the intersecting portion 5 of the connecting bar 4 of the pantographs 3a and 3b is inserted into the bearings of the parts covers 2a, 2b, 2c, 2d, 2f, and 2g. However, the mounting slide shaft 7 fitted in the bent portion 11 of the connecting bar of the pantograph is in a state of being played without being attached to the part covers 2a, 2b, 2c, 2d, 2f, and 2g, and the pantograph 3a 3b and the parts cover 2 as a whole, the slidability is not uniform and unstable, and there is a difficulty in interlocking. As a result, the reciprocation of the telescopic cover is unstable and not smooth, failure, etc. Was the cause of trouble.

  The parts covers 2a, 2b, 2c, 2d, 2f, and 2g have the same width but different lengths. The length of the parts cover 2a is the longest, and the parts are later than the parts cover 2b. Since the telescopic cover 1 moves to one side and the parts covers 2a, 2b, 2c, 2d, 2e, 2f, and 2g of the telescopic cover 1 slide and contract due to the shortening in order over the cover 2g, a plurality of As the stacked parts of the two parts covers 2 become smaller and become a stepped state, the pantograph 3 also becomes loose as shown in FIG. 3, and the connecting bar 4 of the pantograph 3 becomes parallel. First, the telescopic cover 1 when contracted tends to be longer as a whole, which hinders the telescopic cover 1 from being made compact.

  The present invention attaches a plurality of pantographs to a telescopic cover formed by slidably laminating a plurality of thin plate-like part covers, and integrates the telescopic cover with the pantograph according to the movement of the movement mechanism of the industrial equipment. As a whole, the parts cover and the pantograph are linked evenly, stably, and interlocked so that the reciprocating movement of the telescopic cover has a straightness and can be operated safely, reliably and smoothly. Has a purpose.

  Further, according to the present invention, when the telescopic cover moves to one side and the plurality of parts covers slide and contract, the plurality of parts covers overlap each other, and the connecting bar of the pantograph is also parallel. The purpose is to make the telescopic cover compact by shortening the overall length of the telescopic cover when contracted.

  The present invention attaches a plurality of pantographs to a telescopic cover formed by slidably laminating a plurality of thin plate-like part covers, and integrates the telescopic cover with the pantograph according to the movement of the movement mechanism of the industrial equipment. The sliding shaft is inserted into the slit of the slide plate fixed to the even or odd parts of the telescopic cover, and the mounting shaft fitted in the bent part of the connecting bar of the pantograph is slidably inserted. The mounting shaft fitted in the intersection of the connecting bars of the pantograph is rotatably inserted into the odd-numbered or even-numbered parts cover of the telescopic cover.

  In the conventional telescopic cover, the mounting slide shaft fitted in the bent portion of the connecting bar of the pantograph, which is idle without being attached to the parts cover, is fixed to the parts cover of the telescopic cover. Suppressing effect caused by slidingly inserting into the slit of the slide plate, and induction induced by rotatably inserting the mounting shaft fitted in the intersection of the connecting bars of the pantograph to the telescopic cover By synergistic with the action, the overall linkage between the telescopic cover parts cover and the pantograph is increased, and it is slid evenly and stably. There is an advantage that it can operate smoothly.

  In addition, as described above, the present invention is configured so that the mounting shaft fitted into the bent portion of the connecting bar of the pantograph is slidably inserted into the slit of the slide plate fixed to the parts cover of the telescopic cover, By halving the length of the telescopic cover, when the telescopic cover moves to one side and multiple parts covers slide and contract, the length of the stacked telescopic cover is shortened to make the telescopic cover compact. In particular, there is an advantage that it can be used as an optimum telescopic cover when the installation space of a recent downsized industrial device is small.

  Further, as described above, the present invention provides a telescopic cover in which a mounting shaft fitted in a bent portion of a connecting bar of a pantograph is slidably inserted into a slit of a slide plate fixed to a part cover of the telescopic cover. Moves to one side, slides and contracts multiple parts covers, and when the multiple parts covers are slightly displaced to a staircase, the pantograph connecting bars are placed in a parallel state, making it telescopic The overall length of the cover can be shortened, and the length of the telescopic cover part cover described above is halved, which has the advantage that the telescopic cover can be made more compact.
