Description

[0001]
[Industrial application fields]
The present invention relates to a telescopic type telescopic cover attached to a sliding mechanism such as a spindle head of an industrial equipment, a piston, a cylinder or the like, and two or more rows of pantographs are spaced apart from the telescopic cover. It is characterized by being mounted in parallel.
[0002]
[Prior art]
Conventionally, if sliding mechanisms such as spindle heads, pistons, cylinders, etc. of industrial equipment are exposed barely, there is a disadvantage that the oil is scattered and the surroundings are contaminated, and there is a risk of pinching the limbs and clothes of workers. .
[0003]
In addition, foreign materials such as chips and spatter and dust are mixed in and adhered to the sliding mechanism of industrial equipment and the gap formed thereby, resulting in hindering the smooth movement of the sliding mechanism and wear of the sliding mechanism. There was also a problem in design as an industrial machine.
[0004]
As a countermeasure against the above-mentioned problems, it is conceivable to cover the expansion / contraction mechanism of industrial equipment that is exposed naked, with an expansion / contraction cover, but this type of expansion / contraction cover has traditionally been made of cloth or vinyl bellows-like expansion / contraction. A cover has been used, but recently, a telescopic cover in which a plurality of thin metal plate partial covers are slidably stacked is used.
[0005]
However, the partial covers of the telescoping cover of the telescopic type are not separated and connected to each other, and the partial cover does not move uniformly because the partial cover is slid by the partial cover. However, there is a drawback that the sliding is not smooth, does not move straight, often generates abnormal noise, and is easily broken as an extendable cover.
[0006]
Furthermore, as an improvement of this telescoping expansion cover, as described in Japanese Patent Publication No. 3-21297, each partial cover of the metal thin plate is spaced at both ends of a metal square frame. It is attached so as to be bridged, and forms a partial cover frame body like a box lid with the bottom of the central part punched out. The partial cover frame bodies are stacked in a heavy box shape so that they can be slid relative to each other. There is also an expansion / contraction cover with a structure in which an expansion / contraction mechanism for industrial equipment is attached to the space.
[0007]
However, the telescopic cover of the nested type as described above, when sliding, the both sides of the square frame of each partial cover frame are in contact with each other over the entire surface, the contact area is large, the friction Due to the strong resistance, there is a problem that the sliding property is not good, there is a lot of noise due to metal contact, it is easy to break down as a telescopic cover, and it cannot cope with the complex movement of recent industrial equipment.
[0008]
Attempts have also been made to attach a single row of pantographs to the telescoping cover of the telescoping and make the sliding of each partial cover even. However, simply attaching a single row of pantographs can impart straightness to the telescopic cover. However, there is a drawback that both ends of the expansion cover collide with the inner surface of the frame body to generate metallic noise and do not slide uniformly.
[0009]
[Problems to be solved by the invention]
The present invention solves the above-described disadvantages of the telescoping cover of a nested type composed of a plurality of partial covers, and is a thin plate-shaped partial cover having the same width and a different length, and one end of each partial cover. Nested type expansion cover is formed by slidably laminating a plurality of concave and convex protrusions with different lengths in order of length, and is provided on the partial cover of this expansion cover By attaching a pin at each crossing point of the connecting bar of the pantograph to the pin holder or pin mounting seat, and attaching two or more rows of pantographs in parallel at intervals, the expansion cover can be linked together and evenly The purpose of this is to make the sliding of the elastic cover smooth and reciprocating, giving the straight movement to the sliding of the elastic cover, reducing the frictional resistance and metal noise, and reciprocating stably. And complicated movement There is objective earnestly to provide a telescopic cover of the corresponding incoming telescopic.

[Action]
Thin plate-like partial covers with the same width and different lengths, and can slide in the order of the length of multiple pieces with concave and convex protrusions with different lengths formed at one end of each partial cover A telescopic cover is formed by laminating it, and pins at each intersection of the connecting bars of the pantograph are attached to the pin holders or pin mounting seats provided on the partial cover of the expansion cover . When pantographs of a row or more are attached in parallel at intervals, and the telescopic cover is slid by the sliding mechanism of industrial equipment, the multiple partial covers are linked and interlocked with each other by the pantographs. In addition, the pantograph slides smoothly, and one pantograph is prevented from tilting and sliding the telescopic cover of the telescopic type by the other pantograph, and the other pantograph is entered by the one pantograph. In order to suppress the tilting type expansion cover from sliding at an angle, the telescopic type expansion cover moves straight and slides, and both sides of the telescopic type expansion cover cover the inner surface of the frame. Without sliding, there is little frictional resistance and metal sound, and it slides more evenly and smoothly.
