Description

  The present invention mainly relates to a protective cover for machine tools and other industrial industrial machines.

    Conventionally, a telescopic cover used for machining or the like is composed of a plurality of boxes F fitted to each other, and performs a telescopic motion following the movement of the machining or the like. For this reason, a wiper W made of a rubber elastic body, metal, or a composite thereof is fixed to the tip of the box F so that the box F does not come off and be removed, and the load of the box F is applied to the box F terminal. A plate P on which a sliding body or rolling element for supporting was provided. In the telescopic cover extension process, the wiper W and the plate P collided to pull each box F sequentially.

As a result, there has been a problem of strength due to impact sound and impact. In order to alleviate these problems, a rubber elastic body was generally installed and countermeasures were taken. However, in order to cope with further increases in the speed of machine tools, a pantograph was devised as a chain device.
The applicant has devised utility model numbers 3047883 and 3049688.

The chain device was arranged from one to a plurality of rows depending on the size of the telescopic cover. However, since the current chain devices are independent of each other, the telescopic covers are inclined, which causes a problem of causing damage to the telescopic covers.
FIG. 2 is a plan view of a conventional chain device.

With the present invention, a combination of the chain device B and the coupling plate D that connects the chain device C allows a plurality of chain devices to be driven at the same time to prevent individual telescopic covers from tilting and to ensure excellent straight running stability. Excellent results were obtained in the test.

    For machine tools and other general industrial machines, it was necessary to develop a protective cover with low noise and low occurrence of failure, in addition to high-speed response type, to meet the needs of the times.

In order to eliminate such drawbacks, the present inventor has continually improved and connected multiple independent chain devices simultaneously to prevent meandering of the telescopic cover and dramatically improve straight running stability. We have developed a multi-simultaneous drive chain device A that solves the problem and exhibits practically superior performance.
The contents will be described below with reference to the drawings.

    FIG. 3 shows an assembly diagram of the multiple simultaneous drive chain device A according to claim 1. FIG. 4 shows an assembly diagram of the multiple simultaneous drive chain device E according to claim 2.

    The telescopic cover comprising a plurality of boxes fitted to each other according to claim 1, wherein the plurality of simultaneous drive chain devices A for connecting the boxes are made of a rectangular flat metal plate processed to a required length. The chain device B and the chain device C made of a rectangular flat metal plate processed to the required length are connected to the chain device B using the connecting plate D made of the rectangular flat metal plate processed to the required length. And the chain device C are connected to each other, and the chain device B and the chain device C are synchronously driven.

Next, the assembly method of claim 1 will be described with reference to FIG.
The center shaft hole BP1 and the side shaft hole CP1 are locked to the fulcrum F1 provided in each box F in the multiple simultaneous drive chain device A configured by connecting the chain device B and the chain device C using the connecting plate D. .

    Next, in the telescopic cover comprising a plurality of boxes fitted to each other according to claim 2, the plurality of simultaneous drive chain devices A for connecting the boxes are formed of a rectangular plane metal machined to a required length. A chain device B made of plate-making material and a chain device C made of rectangular-plane metal plate material processed to a required length using a connecting plate D made of a rectangular flat metal plate material processed to the required length A chain device B and a chain device C are connected to each other, and the chain device B and the chain device C are synchronously driven. C and the chain device B are connected using a connecting plate D made of a rectangular flat metal plate processed to a required length, and the chain device B and the chain device C arranged in a plurality of rows are synchronously driven.
