Description

Description Telescopic cover that slides in the cross direction

The present invention relates to a telescopic cover that covers an industrial machine and slides in a cross direction according to a moving mechanism such as a spindle head, a bed, a table, a column, a piston, a cylinder, and an ATC cover of the industrial machine. . Background art

Conventionally, for example, when cutting metal with a cutting machine, the power of industrial machinery that has a moving mechanism such as cutting chips and spatter (hereinafter referred to as cutting chips) generated by cutting metal, Intrusion into the moving mechanism has hindered the smooth sliding of the moving mechanism of the industrial machine and caused the moving mechanism to wear, resulting in deterioration of the performance of the industrial machine.

In particular, when cutting metal with an ultra-high-speed cutting machine, a large amount of cutting water, etc., is poured from the top of the cutting machine into the cutting area to eliminate chips and cool the heat generated by the metal. If water, etc., flows into a moving mechanism such as the spindle head of a nearby industrial machine, or if chips enter with a large amount of cutting water, etc., the moving mechanism of the industrial machine will become 鲭, and foreign matter will be mixed in. The slidability of the machine deteriorated, leading to a decrease in the performance of the industrial machine.

As a countermeasure against the above-mentioned inflow of cutting water and the intrusion of cutting chips, industrial machinery having a moving mechanism, such as a spindle head, which is bare and exposed, was covered with cloth or vinyl bellows. In recent years, instead of these, a telescopic cover that slides back and forth in one direction, in which multiple partial covers of metal plates are slid one on top of the other, due to problems with strength, etc. You And has begun to be used.

For example, as shown in FIG. 1, a large number of partial covers 2 ae, which are rectangular metal sheets, are laminated, and each partial force bar 2 ae is configured to slide left and right. A thin long plate-shaped rubber blade 3 is attached to the tip of ae, where it comes into contact with the other partial cover 2 ae. Felt, vinyl, etc. were used.

As shown in FIG. 2, the telescopic cover 1 covers the industrial machine 5 and fixes a partial cover 2 a at one end to the moving mechanism 4 of the industrial machine 5, and a partial cover 2 at the other end. e was fixed to the fixing mechanism 6 of the industrial machine 5, and each partial force bar 2 ae was reciprocated only in one of the left and right directions according to the left and right movement of the moving mechanism 4 of the industrial machine 5.

That is, as the moving mechanism 4 of the industrial machine 5 moves to the left, the respective cover 2 ae of the telescopic cover 1 is extended to the left, and the rubber blade 3 attached to the tip thereof is moved to the left. In this way, chips and cutting water are discharged to the outside by sliding in the direction, and each partial force bar 2ae moves rightward as the moving mechanism 4 of the industrial machine 5 moves rightward. By contracting, the blade 3 is slid to the right, and the telescopic cover is reciprocally slid in one direction to the left and right to discharge chips, cutting water, etc. Attempts were made to prevent cutting water, etc., from entering the moving mechanism 4 of the industrial machine 5 inside through the gaps between each cover 2 ae of the telescopic cover 1.

However, in recent industrial machines, the moving mechanism such as the spindle head, bed, table, column, piston, cylinder, and ATC cover reciprocates only in one direction: left, right, front, back, and up and down. In addition, there are some that reciprocate in the cross direction of front and back and left and right, For the moving mechanism of industrial machinery, there was a problem that the conventional telescopic cover that reciprocates in one direction cannot cope.

In addition, the above-mentioned telescopic cover (partial cover) is often made of a thin plate of ordinary steel (SS41, SPCC, etc.), and because of the thickness and weight, a load is applied when the telescopic cover slides. As a result, frictional resistance increased, and there were problems with slidability, durability, abrasion resistance, physical strength, lightness, and the like.

In addition, the above-mentioned telescopic cover is often made of a thin plate of stainless steel plate (SUS301H, SU304304HT, SU63, SUS631, etc.), and the price or corrosion resistance, There were difficulties in practicability in that quenching and tempering required heat treatment.

Furthermore, in the above-described telescopic cover 1 made of a thin metal plate, the partial force bars 2a to 2e are independent and separated from each other, and do not have a connected mechanism. For example, the partial cover 2a is partially covered by the partial cover 2a. In most cases, the partial force bars 2a to e do not slide at a uniform distance, and the partial force bars 2a to e There is variation in the movement, only the easy-to-move partial cover slides, and there are some partial covers that do not move, so that the entire sliding as the telescopic cover 1 is not smooth, does not go straight, and generates noise. There were many inconveniences such as easy breakdown.

In addition, the rubber blade 3 attached to the conventional telescopic cover 1 described above tends to have a large plate thickness (3 to 10 mm) and a large gap between the blades 3 (10 to 20 mm). There is a drawback that chips and water for cutting and the like penetrate into the inside from the gaps formed by this, and the partial covers 2 a to e are large and inevitably heavy, and the telescopic cover 1 Has the disadvantage of becoming large and heavy, and as blade 3 Were also liable to wear, poor in slidability, and defective in durability.

Further, the rubber blade 3 provided in the above-described conventional telescopic cover 1 is a single flat bar, and when the blade 3 slides, the entire lower part of the blade 3 has a partial force bar. 2 It is expected to slide in contact with the entire surface of a to e, but depending on the state of wear and deterioration of blade 3 and the unevenness of the contact surface of each part cover 2 a to e, the blade 3 It is difficult for the entire lower surface to contact the entire surface of each of the partial force bars 2a to 2e to make surface contact.

In other words, the surface of a part of the lower portion of the blade 3 often contacts the surfaces of the partial force bars 2a to 2e to make point contact, and a gap is formed between the blade 3 and its contact surface, and the blade 3 There are problems such as intrusion of powder, cutting water, etc., and deterioration of the sealing performance and swiving performance of the blade 3.Especially, each partial force bar 2a ~ e is circular or elliptical, When the blade 3 was mounted in a ring shape, point contact was liable to occur, and the sealing performance and the sweeping performance of the blade 3 were likely to deteriorate.

Further, those which are attached rubber blade 3 to each partial cover one 2 a ~ _e of a conventional telescopic cover one 1 described above is performed only on-edge portion of each partial power bar 2 a ~ e In many cases, large gaps are formed at the left and right ends of the partial force bars 2a to e and at the rear end where rubber blades 3 are not attached. Intrusion was inevitable.

In particular, in the case of a telescopic cover that reciprocates in the cross direction, it is difficult to attach a blade to all four sides of the sliding part, and there has been a problem that cutting chips, cutting water, etc. penetrate from a part where the blade is not attached. .

The present invention covers an industrial machine and a moving mechanism such as a spindle head of the industrial machine. The front and rear, left and right, left and right and up and down crosses of the partial cover on which the ultra-thin metal plate blade of the telescopic cover is fixed are almost coplanar with the front and back and left and right, left and right and up and down cross directions. The cutting chips and cutting water existing on the surface of the telescopic cover are discharged to the outside while the chips and cutting water are removed from the telescopic cover through the gap of the telescopic cover. The purpose is to prevent intrusion into the moving mechanism, etc., to maintain the smooth sliding property of the moving mechanism of the industrial machine, to fully exert the performance of the industrial machine, and to make the blade of the ultra-thin metal plate. By increasing the hardness, elasticity, physical strength, etc. of the blade, the blade is made smaller and thinner, the contact area is reduced, and the Reduction of the frictional resistance, durability, sliding property, sealing property, there is a purpose to improve the Sistan Bing property.

Further, the present invention uses a high-strength, multi-layer stainless steel as a material of each partial force bar of the telescopic force bar that reciprocates in the cross direction described above, and reduces the thickness of each partial force bar, The purpose is to make the telescopic cover compact and lightweight, and to increase the elasticity, slidability, abrasion resistance, durability and physical strength of the telescopic cover.

Further, the present invention provides a blade which is fixed to a sliding portion at an end of each partial cover of the telescopic cover which reciprocally slides in the above-described cross direction, has a carbon content of 0.03 to 0.1%, Hardness as a blade by fixing the blade of an ultra-thin metal plate made of steel or stainless steel containing 10 to 20% and having a thickness of 0.01 to 0.3 mm. , Elasticity, physical strength, etc., making the blade smaller and thinner, making the contact area smaller, reducing the frictional resistance of the blade, durability, slidability, sealing The purpose is to significantly improve the sweeping performance.

Further, the present invention provides a telescopic slide which reciprocates in the cross direction described above. As a blade fixed to the sliding point at the end of each cover of the cover, it is divided into a number of ultra-thin metal plate blades, and by making many point contacts when sliding the blade, Aims to further improve the discharge of cutting chips, cutting water, etc., and the sealing performance etc. by bringing the blade close to surface contact ₀

Further, according to the present invention, the pantograph is attached to the telescopic cover that slides back and forth in the cross direction described above, and each of the partial covers is simultaneously slid at a uniform distance without any variation, so that the telescopic cover has straightness. The purpose is to keep the movement of the moving mechanism of the industrial machine smooth and to make full use of the machine performance.

Furthermore, the present invention uses a high-strength, multi-layer stainless steel as a material of the pantograph attached to each partial force bar of the telescopic cover that slides back and forth in the cross direction, and reduces the thickness of each partial force bar. The purpose is to make the telescopic cover compact and lightweight, and to increase the elasticity, slidability, wear resistance, durability and physical strength of the telescopic cover.

An example in which the telescopic force bar sliding in the cross direction of the present invention is attached to an industrial machine will be described. As shown in FIG. 3, the telescopic force bar 1 sliding in the cross direction is provided as shown in FIG. It consists of two sets of center telescopic covers 12 and two sets of side telescopic covers 13, for example, the partial cover of the center-telescopic cover 12-sliding direction of 12 a to d If the slider slides up and down, two sets of side telescopic covers 13 are provided on both sides of the center telescopic force bar 12 in the direction perpendicular to the sliding direction of the 12 a to d. With partial covers 13a-d, these two sets of side telescopic force bars 13 The partial covers 13a to 13d are configured to slide left and right on substantially the same plane.

Each center telescopic cover 12 is formed by slidably stacking partial covers 12 a to d made of a thin metal plate of 0.5 to 3 mm in thickness, such as stainless steel, which is rectangular. Each side telescopic cover 13 is also formed by slidably laminating partial covers 13a to 13d made of a thin metal plate of 0.5 to 3 mm in thickness, such as stainless steel.

When the partial covers 1 2 3 to 1 and 1 3 a to d are slidably laminated, depending on conditions such as the direction of discharge of cutting chips and cutting water and the direction of movement of industrial machinery, for example, , The partial cover 12a is the topmost layer, and the partial covers 12b to d are sequentially laminated at the lower level, or the partial cover 12a is the lowest layer, and the partial cover 12b To d may be sequentially stacked on top of each other (the same applies to 13 to 13 d).

Partial cover 1 2 ₃ to 3 び 1 3 ₃ （(Fix the ultrathin metal plate blade 3 at the sliding part at the end of 1 and press the sliding surface of each partial force bar. It is configured to slide.

For attaching the blade 3 extremely thin metal plate, as shown in FIG. 4, part cover one 1 2 3 (1 Oyobi 1 3 ₃ ~ (a very thin metal plate to the sliding point of the first end A long plate-like blade 3 is fixed, or as shown in Fig. 5, one side of the sliding part at the end of the partial covers 12a-d and 13a-d Blades 3 of ultra-thin metal plate may be fixed at intervals of 1 to 5 mm, and furthermore, as shown in Fig. 6, the ends of partial covers 12a to d and 13a to d A large number of rectangular ultrathin metal plate blades 3 may be fixed at intervals of 1 to 5 mm on the entire surface of the sliding portion.

A pantograph 7 is attached to the center telescopic cover 1 2 and the side telescopic power It is preferable to improve the straightness and the sliding property as described above, and the mechanism for mounting the pantograph 7 is, for example, as shown in Fig. 7, the partial cover 12a to d of the center-telescopic cover 12 Rotating shafts 9 of different lengths rotatably attached to the bearings 10 fixed to the lower side face are rotatably inserted at the intersections adjacent to the connecting shafts 15 of the connecting bars 8 of the pantograph 7, respectively. Instead of the bearing 10, a mounting seat or other mounting mechanism may be provided (the same applies to the side telescopic cover 13).

The center cover 14 with a mounting hole 11 for inserting the moving mechanism 4 such as the spindle head of the industrial machine 5 is inserted between the two sets of center telescopic covers 12 and slides. In this case, the center cover 14 is positioned at the top layer, and the two sets of center bar telescopic force bars 12 are sequentially positioned at the lower layer. Therefore, if it is configured to slide as a whole, the liquid such as cutting water and the solid such as cutting chips are better discharged to the outside, and it is easy to prevent intrusion into the moving mechanism of the internal industrial machine. Become.

In addition, as described above, the center telescopic cover 1 and the side telescopic cover 13 are configured so that they slide in a direction orthogonal to the cross direction. In order to provide the side telescopic force bar 13 of the two sets, the two sets of the center telescopic cover 12 are located in the upper layer, and the two sets of the side telescopic cover 13 are positioned in the lower layer. When it is configured to move, the liquid such as cutting water and the solid such as cutting chips are discharged to the outside, and it is easy to prevent the intrusion of the internal industrial machine into the moving mechanism. Note that, depending on the use of the telescopic cover 1, contrary to the above-mentioned case, the center telescopic cover 12 is located at the lower layer, and two sets of side telescopic covers 13 are located at the upper layer, and It may be configured to slide. As shown in Fig. 8, the center telescopic cover 12 with the ultrathin metal plate blade 3 and the pantograph 7 attached to it slides on both sides into the central holder 17 with a U-shaped cross section. The side telescopic cover 13 with the ultra-thin metal plate blade 3 and the non-graph 7 attached to it can be slid into the central holder 18 with a U-shaped cross section. Insert.

The operating state of the telescopic cover 1 that slides in the cross direction according to the present invention will be described with reference to FIG. 8. An industrial machine 5 near a cutting machine (not shown) is connected to a center telescopic cover 12 described later and a side telescopic cover. Cover with a telescopic cover 1 consisting of a cover 13 and a moving mechanism 4 such as a spindle head of an industrial machine 5 into a mounting hole 11 of a center cover 14 of a center telescopic cover 1 2.

2 sets of center telescopic cover 1 2 partial cover 1 2 a to j and 2 sets of side telescopies according to the moving state of the moving mechanism 4 such as the spindle head by driving the industrial machine 5 The partial cover 13 of the copic cover 13 is slid on substantially the same plane.For example, when the moving mechanism 4 of the industrial machine 5 moves downward, the partial cover 1 of the center telescopic cover 1 2 2 a to j contract downward and slide, while the other center telescopic cover 1 2 partial cover 1 2 a to j extend downward and slide, and the moving mechanism 4 Is moved upward, the partial cover 12 of one center telescopic cover 12 extends upward and the partial cover 12 of the other center telescopic cover 12 extends. a ~; j contracts upward and slides (sa Id telescopic cover-13 part cover 13 ae is stationary).

Next, when the moving mechanism 4 moves to the left, the partial covers 13 a to 13 e of the side telescopic cover 13 contract to the left and slide. In both cases, when the partial cover 13 of the other side telescopic cover 13 extends and slides to the left, and when the moving mechanism 4 moves to the right, the other side telescopic cover 13 The cover 13a to e of the side telescopic cover 13 expands and contracts to the right and slides, while the partial cover 13a to e of the other side telescopic cover 13 contracts and slides to the right (center Partial cover 1 2 a to j of rescue force bar 12 is stationary).

When the moving mechanism 4 moves to the left after moving downward, the partial cover 12 a to j of one center telescopic cover 12 contracts downward and slides, while the other center telescopic cover slides. After the partial covers 12 a to j of the cover 12 extend downward and slide, they are almost on the same plane, while the partial cover 1 2 a to e of the side telescopic cover 13 is left The side cover 13a of the side telescopic cover 13 extends leftward and slides while contracting in the left direction. Furthermore, when the moving mechanism 4 moves rightward after moving upward, the partial covers 12 a to j of one center telescopic cover 12 extend upward and slide, while the other center telescopic cover slides. After the partial covers 12 a to j of the force bar 12 are contracted upward and slid, the partial covers 13 a to e of the side telescopic cover 13 are almost coplanar. While extending rightward and sliding, the other side telescopic cover 13 of the other side telescopic cover 13 contracts rightward and slides.

As described above, in response to the movement of the moving mechanism 4, the center telescopic cover 12 extends and contracts and slides, and the side telescopic cover 13 also extends and contracts and slides on almost the same plane. At this time, the pantograph 7 also expands and contracts and slides, and the slidability of the center telescopic cover 12 and the side telescopic cover 13 is improved. While improving the running performance, at the same time, the blades 3 fixed to the center telescopic cover 12 and the side telescopic cover 13 prevent the chips and cutting water from flowing into the inside of the telescopic cover 1 neatly. To be discharged.

Center Telescope Cover 1 and Side Telescope Cover 1

As the material 13, in addition to the above-mentioned stainless steel, a high-grade material having a soft ferrite phase, a hard martensite phase, and a fine mixed structure mainly composed of 17% Cr and 12% Ni is used. It may be formed of an ultra-thin metal plate of stainless steel with a multi-layer structure to enhance the physical strength and wear resistance of the telescopic cover.

The center telescopic cover 1 2 partial cover 1 2 a to d and the side telescopic cover 13 partial cover 13 3 a to d can be square, circular, oval, A lid type, a roof type, a box type, etc. may be used, and the number of these telescopic covers is desirably 3 to 30, and the dimensions are width 5 to: I 00 cm, length 13 to 50 cm is appropriate.

Regarding the width and length of the partial covers 12a-d and 13a-d described above, the width and length of each partial force bar may be different. For example, the center telescopic cover 12 The partial cover 1 2a is 5 cm longer than the partial cover 1 2b, the partial cover 1 2b is 5 cm longer than the partial cover 1 2c, and the partial cover 1 2c is 5 cm longer than the partial cover 1 2d. It may be longer and have a different length.

As shown in Fig. 4, the blade 3 of the ultra-thin metal plate has a partial cover 12a-d and 13a- Is the same as that of each component bar, and a long plate-shaped blade 3 of an ultra-thin metal plate having a thickness of 0.01 to 0.3 mm may be fixed, or as shown in FIG. Each part On one side of the sliding part at the end of the component bar, a pole with a width of 0.5 to 3 cm and a length of 1 to 5 cm and a thickness of 0.01 to 0.3 mm A large number of blades 3 of thin metal plate may be fixed at intervals of 1 to 5 mm, and furthermore, as shown in FIG. On the whole surface, the width is 0.5 ~: 3cm, length power ';:! A large number of blades 3 of an ultrathin metal plate that is a rectangle of up to 5 cm and a thickness of 0.01 to 0.3 mm may be fixed at intervals of 1 to 5 mm .

When fixing many blades 3 of ultra-thin metal plates, the number of blades 3 depends on the size of the partial cover 2, but in the normal case, 2 to 8 blades / ^κ10c ; m (per partial cover) is appropriate

Blade 3 is made of steel or stainless steel with a carbon content of 0.03 to 0.1% and a chromium amount of 10 to 20% (hereinafter simply referred to as low carbon content and high chromium content). It is best to use this amount of material (stainless steel), which is a newly developed material that has high strength (tensile strength of 200 to 200 N / mm-). For example, Nisshin Steel's high-strength stainless steel is sold under the product numbers of SUS631, NSSHT1770, NSSHT1960, and NSSHT200. Have been.

In addition, stainless steel with a low carbon content and a high chromium content has excellent properties such as high hardness (abrasion resistance) and small reduction in strength due to welding. It is suitable to be used as an ultra-thin, small, lightweight, high-precision blade 3 with a thickness of 0.01 to 0.3 mm.

The carbon content of stainless steel with low carbon content and high chromium content, used as blade 3 of ultra-thin metal plate, is set to 0.03 to 0.1% by using blade 3 This is to prevent the decrease in strength that occurs when the steel is directly welded to the partial cover 2.If the carbon content of the stainless steel is less than 0.03%, the weldability is further improved, but the hardness of the blade 3 is improved. Can have difficulties Also, if the carbon content of the stainless steel exceeds 0.1%, the strength is reduced when the blade 3 is directly welded to the partial cover 2.

The reason that the chromium content of stainless steel having a low carbon content and a high chromium content is made 10 to 20% is to provide hardness (abrasion resistance). If the amount is less than 20%, the blade 3 cannot have sufficient hardness (abrasion resistance). If the chrome amount exceeds 20%, the hardness can be further increased, but the elasticity is increased. This may cause difficulties.

Furthermore, the thickness of stainless steel with a low carbon content and a high Ku content is made into an ultra-thin metal sheet with a thickness of 0.01 to 0.3 mm (preferably 0.05 to 0.1 mm). The purpose of this is to make use of the high strength (tensile strength) and elasticity when using it as the blade 3, and to make the blade 3 thinner, smaller, lighter, more compact and higher performance, and to improve the telescopic cover. (1) The contact area with the sliding surface is reduced, frictional resistance is reduced, and no extra load or load is applied to the sliding part or moving mechanism of the telescopic cover (1), and the driving power of the telescopic cover (1) is reduced. This is to save money.

When the thickness of stainless steel of low carbon content and high chromium content is less than 0.01 mm, the hardness and physical strength when used as blade 3 are sufficient. In addition, manufacturing a blade 3 with a diameter of less than 1 mm is troublesome and costly in manufacturing and processing, and has a low carbon content and a high chromium content. When the thickness of the stainless steel exceeds 0.3 mm, the elasticity and lightness of the blade 3 become difficult.One end of the blade 3 of the ultra-thin metal plate slides on the end of the partial cover 2 Welded directly to the part and protruded from the partial cover 2 (0.05 to lmm) The part is used as a blade, but the shape of the blade 3 is a flat plate, and any shape can be used as long as the tip of the blade 3 can protrude from the partial cover 2. . The means for welding one end of the blade 3 to the partial cover 2 is preferably electric spot welding or laser welding, but it goes without saying that other welding methods may be used.

In fixing the blade 3 to the partial cover, in addition to the welding described above, apply adhesive to the entire sliding part at the end of the partial cover 2 and the blade 3, or apply adhesive. When the blade 3 is fixed to the entire sliding portion at the end of the partial cover 2 with a rivet, the sealing can be reliably performed so that cutting water or the like does not enter, and the joining becomes simple and easy.

Furthermore, to fix the blade 3 of the ultra-thin metal plate to the sliding point at the end of the partial cover 2, bend the blade 3 of the ultra-thin metal plate into a square shape or a square shape. The precision of the blade 3 is further improved, the stiffness of the blade 3 is further strengthened, more stable pressing performance is maintained, and the sealing performance and wiving performance of fluids and contaminants can be significantly improved.

Stainless steel may be used as the material of the vantagraph 7, but it is finely mixed with a soft ferrite phase and a hard martensite phase mainly containing 17% Cr-2% Ni. The physical strength of the pantograph 7 may be increased by using a high-strength multi-layer stainless steel having a structure. Stainless steel may be used as the material of the mounting shaft 9 of the pantograph 7, but if stainless steel subjected to immersion nitriding is used, the mounting shaft 9 is extremely hardened because its surface is hardened. It has excellent slidability and physical strength, and even if an excessive force is applied when it is used for the mounting shaft 9 of the connecting bar 8 of the pantograph 7 of the telescopic cover 11 attached to the moving mechanism of the industrial equipment described above, There is no backlash due to the surface breakage and mounting Since the shaft 9 is not hardened to the inside, the shaft 9 is flexible, the mounting shaft 9 does not bend or break, and the entire end of the pantograph 7 is improved in elasticity and slidability. Operate smoothly and smoothly for a long time. Further, as the connecting bar 8 of the pantograph 7, when a laminate of 2 to 10 spring stainless steel sheets having a thickness of 0.1 to 3 mm is used, a connecting bar formed by stacking the stainless steel sheet steels is used. In the pantograph 8, since the elasticity, the paneling property, and the physical strength are further enhanced, and the dynamism coefficient is further increased, the pantograph 7 can be made highly elastic.

In other words, even when the telescopic cover 1 is used as the pantograph 7 and an excessive force is applied, the connecting bars 8 made of thin and laminated spring stainless steel sheets are mutually folded, buffered and withstand. The pantograph 7 does not bend or bend, and further improves the stretchability, slidability, and straightness of the pantograph 7, and the pantograph 7 operates more stably and smoothly for a longer period of time.

For mounting the pantograph 7 on the rectangular center telescopic cover 1 2 a to d and the partial power of the side telescopic cover 13 of the rectangular center telescopic cover 1 2 with the same width but different length When the partial cover 2 a to d and the partial cover 12 a to d are completely contracted, the portions (projections) having different lengths become spaces, so the bearing 10 is provided in this space. It is recommended to attach the mounting shaft 9.

However, when attaching the pantograph 7 to the partial cover 13 a to d of the rectangular side telescopic cover 13 with the same width and length, when the partial cover 13 a to d is completely contracted, Since there is no space with different parts (projections) and no space, as shown in Fig. 8, one end of the side cover 13a-d of the side telescopic cover has slits 1 of different lengths. 6 and the bearing 10 is fixed to this slit 16 and the mounting shaft 9 By wearing, the side telescopic cover 13 can be made compact.

If the pantographs 7 attached to the center telescopic cover 12 and the side telescopic force bar 13 are provided in parallel in two or more rows and at intervals (10 to 50 cm), the sliding of these telescopic covers And straightness can be improved.

In particular, when the connecting bars 8 are laminated with a thin high-strength, multi-layered stainless steel, even if an excessive force is applied to the pantograph 7, the laminated connecting bars 8 are mutually buffered to withstand and survive. In addition, the slidability and straightness of the bantagraph 7 are further improved, and the pantograph 7 operates more smoothly for a longer period of time.

Further, when oil such as lubricating oil is injected once between the side surfaces of the stacked connecting bars 8, the oil such as lubricating oil permeates into the entire space between the connecting bars 8 by capillary action. Since the oil such as lubricating oil can always be kept impregnated on the side surface of the connecting bar 8, the lubricating oil oozes out from the side surface of each connecting bar 8, and the connecting bar 8 and the mounting shaft 9 Since the lubricating oil is constantly supplied to the surrounding area, the slidability and straightness of the resilient pantograph 7 are further improved, and the pantograph 7 operates much more smoothly over a longer period of time. The connecting bar 8 and the mounting shaft 9 are not worn, and no abnormal noise or failure occurs.

For mounting the pantograph 7 on the telescopic cover 1, as shown in FIG. 9, the mounting shaft 9 of the pantograph 7 is fixed to the partial cover 2a to 2d of the telescopic cover 1 and the mounting slide of the pantograph 7 is performed. The shaft 19 may be slidably inserted into the slit guide 21 of the slit plate 20 fixed to the partial covers 2a to 2d of the telescopic cover 1. Center cover with pantograph 7 and ultrathin metal plate blade 3 Partial covers 2 a to d for telescopic pick-up cover 12 and partial force cover 12 for side telescopic pick-up cover 1 2 a to d Can fix the rollers and run along the guide rails to improve slidability and reduce frictional resistance.

When the pan tag raffle 7 is attached to the 2a to 2d of the part of the telesco bik kanoku 1 cover, the sliding mechanism 4 of the spindle head etc. of the industrial machine 5 and the fixing mechanism of the industrial machine 5 when sliding. In this case, the partial cover 2a and the partial cover 2d are concentrated, and the force is applied to the partial cover 2a and the partial cover 2d. A reinforcing plate (not shown) is fixed to one or both of the moving mechanism 4 for the head or the like and the fixing mechanism 6 for the industrial machine 5, and the partial force bar 2a or the partial cover 2d is attached, and the pantograph is attached to the reinforcing plate. 7 should be attached.

Industrial applicability

According to the present invention, the telescopic cover on which the ultra-thin metal plate-shaped blade is mounted can be moved in the cross direction of a moving mechanism such as a spindle head of an industrial machine. It can smoothly slide back and forth, and can discharge chips and cutting water to the outside, and prevent chips and cutting water from entering through gaps in the telescopic cover. This has the advantage of maintaining the smooth movement of the moving mechanism of the industrial machine and, at the same time, making full use of the performance of the industrial machine. In particular, when high-strength, multi-layer stainless steel is used as the material of the telescopic cover that slides back and forth in the cross direction, the partial cover plate of these telescopic covers is used as compared to the case where this material is not used. There is a merit that the thickness can be reduced, and the telescopic cover can be reduced to 1Z2 to 1/5 and the weight can be reduced to 1/2 to 1/5. The advantage of these telescopic force bars is that the elasticity, slidability, abrasion resistance, durability, and physical strength can be increased 2 to 5 times compared to when this material is not used. is there.

Also, according to the present invention, if a very thin metal plate-shaped blade is fixed to one or all surfaces of the telescopic cover that slides back and forth in the cross direction, chips and water for cutting and the like enter through the gap of the telescopic cover. Can be prevented more reliably, the smooth movement of the moving mechanism of the industrial machine can be maintained, and the performance of the industrial machine can be fully exhibited.

In particular, the use of ultra-thin metal plate blades made of stainless steel with a low carbon content and a high chromium content can reduce the weight and reduce the contact area with the partial cover (1.8 to 1.8). Can reduce the frictional resistance of the blade, and can significantly improve the durability, slidability, sealing, and sweeping performance (3 to 10 times). The thickness of the blade can be reduced to 1/8 to 1/25 compared to blades made of steel, etc., making the entire telescopic cover more compact (1/2 to 1/5) and lighter in weight. (1Ζ3 to 1Ζ7) is possible.

Further, according to the present invention, by attaching the pantada rough to the telescopic force bar that reciprocates in the cross direction, the telescopic cover can be partially covered at the same time, at a uniform distance, without variation, and noise can be reduced. The telescopic force bar has the advantage of improving the slidability and straightness of the telescopic force bar.

In particular, when high-strength, multi-layer stainless steel is used as the material for the pantograph, the advantage of making the pantograph thinner, more compact, and lighter than when this material is not used is provided. is there.
