In machine tools and similar mechanical assemblies including relatively slidable machine components it is customary to provide protecting means surrounding the slideways against the ingress of dirt, metal cuttings and other foreign particles that would otherwise be liable to damage the precisely machined slideway surfaces. Such protecting means may comprise collapsible casings such as accordion-pleated bellows made of suitable plastic of leather, or telescopically interfitted metallic elements, in order to maintain an enclosure around the length of the slideways regardless of the relative position between the slidable components.
While such conventional protection means quite effectively prevent the ingress of large metal cuttings, they fail to provide adequate protection against smaller abrasive particles which are well capable of seriously damaging the slideway surfaces. Such particles find their way through the spaces and interstices present between the protective casing and sides of the slideways and/or between adjacent telescopic sections of the collapsible casing. Small metal particles are especially apt to enter during operation of the machine tool when a multitude of minute metal particles are floating in the air around the machine. When the machine as a whole is being cleared of cuttings the protecting covers of the prior art actually do more evil than good since they tend to collect the floating abrasive particles, prevent adequate visual check of the state of cleanliness of the slideways and interfere with the cleaning of the surfaces. In fact in view of this many users of machine tools prefer to remove such collapsible covers entirely and operate the machine tools without them, even though this means the necessity of very frequent cleaning operations and still does not prevent a shortening of the useful service life of the slideways.
It is an object of this invention to provide improved protection means for slideways in mechanical assemblies especially large-sized machine tools, which will provide a positive and effective protection against the entry of abrasive and other foreign matter without requiring practically any supervision. A broad object is to improve the surface condition of slideways and thus preserve high accuracy in machining operations and machine performance generally over prolonged periods of time.
The invention essentially contemplates means for permanently injecting gas, e.g. air, under superatmospheric pressure into an enclosure, such as a collapsible cover or casing of any of the aforementioned types, surrounding the slideway.
An exemplary embodiment of the invention will now be described for purposes of illustration but not of limitation with reference to the accompanying drawings where- FIGURE 1 is a side elevational view, with parts broken away, of a milling and boring machine to which the invention is applied;
FIGURE 2 is a section on line II-II of FIGURE 1;
FIGURE 3 is a corresponding plan view with the standard of the machine shown in section on line III-III of FIGURE 1;
FIGURE 4 is a larger scale view of a detail; and
3,148,003 Patented Sept. 8, 1964 FIGURE 5 is a partial view along the line 22 of FIGURE 1 and shows the blower intake line provided with an air filter instead of an elevated intake conduit as in FIGURES 1 and 2.
The milling and boring machine illustrated is of a conventional type including an elongated horizontal bed or bench 2, a standard 1 upstanding from and movable longitudinally of the bed on the longitudinal slideways 5, 6 and 7; a slide 4 displaceable vertically along the standard 1 on vertical ways 41, 42 and 43; and a milling and boring head 3 displaceable along the slide 4 on horizontal ways normal to the slideways 5, 6 and 7.
Collapsible protection means are provided for enclosing the slideways 5, 6, 7 of the bench, and include two sets of telescopically interfitted elements respectively designated 11a and 11b. The set of elements 11a extend from one end of the bench 2 to one side of standard 1 and the set of elements 11b extend from the other end of bench 2 to the other side of standard 1. Each set comprises a number of, e.g. seven, channel shaped sheet metal elements such as 12, 13, 14 15, having flanged sides slidably engaging side flanges 5 and 7 of the bench 2 and telescopically engaging one another; antifriction means may if desired be provided between the adjacent elements and between each element and the bench. FIGURE 1 shows the standard 1 positioned ator near its endmost right hand position, and accordingly the left hand set of cover elements 11a is completely expanded while the other set 11b is retracted or collapsed. It will be obvious that abrasive particles and the like are able to penetrate the casing structures 11a and 11b through gaps and interstices such as the gaps 21, 22, 23 between the adjacent channel elements and the gaps such as 24, 25 between the channel elements and the bench 2.
In accordance with the invention, air under superatmospheric pressure is discharged into the enclosures defined by the cover sections 11a and 11b around the bench slideways. For this purpose, referring to section 11a, a plurality of vertical longitudinally spaced air ducts 27 are provided within the bench 2 with their upper ends fitted with nozzles 28 opening upwards into apertures formed in the upper surfaces of the bench as clearly shown in FIGURE 3. Each air nozzle 28 has a butterfly valve 29 pivoted in it for adjusting the flow of airthrough it. All the air ducts 27 have their lower ends connecting with a manifold 31 extending along the base of the bench 2 and connected with the output line 32 of a blower 33 having a rising intake pipe 35 opening at its upper end at a substantial elevation so as to draw in air from a region of the atmosphere in the workshop that is substantially free from floating metal particles, or from the outer atmosphere. A cover 36 over pipe 35 prevents entry of rain. In respect to the other casing section 11b there is provided a similar arrangement including a blower 33a delivering into a manifold 31a with which connect the spaced vertical air ducts 270, all these parts corresponding to the correspondingly numbered parts earlier described.
In the embodiment shown the veritcal slideways 41, 42, 43 formed on a side of standard 1 are similarly provided with the improved protection means. The collapsible cover in this case is provided as an accordion-type casing of flexible material in two sections, an upper section 44:: extending from the top of the slide 4 to a point near the top of standard 1, and a lower section 44b extending from the bottom of slide 4 to a point near the base of standard 1. Although each casing section in this instance is substantially continuous, still there are interstices such as 47, 48 (FIGURE 3) between the sides of the casing and the standard which it is impossible to seal; abrasive metal particles are therefore liable to penetrate into the casing and damage the surfaces of slidea ways 41, 42, 43. According to the invention, a blower 51 is mounted near the top of standard 1 beneath a hood 52 formed with louvring 53 for the intake of air. The outlet pipe 54 of the blower is connected with a vertical manifold 55 extending down the standard and having one or preferably more air ducts 56 extending from a side of it and fitted with end nozzles 57 opening centrally of the side surface of the standard 1 in which the slideways 41, 42, 43 are formed. Each nozzle 57 has a pivoted airflow adjusting valve 58 in it.
The operation of the system described will be immediately apparent from the foregoing description and it will be evident that the superatmospheric pressure maintained in all of the collapsible covers or casings will elfectively prevent the entry of foreign materials including the many minute but abrasive metal particles produced during the operation of the machine and which otherwise constitute a serious menace to the proper surface condition of the slideways.
Clearly the invention may be embodied in may other ways than that shown. A common blower may be used for both collapsible casing sections associated with each slideway direction, or indeed a single blower may be used for all the slideways. As is shown in FIGURE 5 of the drawing, air filter or strainer means 35' may be provided for cleaning the air delivered by the blower or blowers into the casings, instead of or in addition to using elevated intake pipes such as 35. The covers or casings surrounding the slideways may be constructed otherwise than shown. The air nozzles may vary in number, position and construction. The invention is, of course, applicable to any type of machine, especially though not necessarily machine-tools, having relatively slidable machine components.
