United States Patent 3,212,827 SLIDE AND WAY CONSTRUCTION Henry J. Brettrager, 5410 East St., Saginaw, Mich. Filed May 6, 1963, Ser. No. 277,998 8 Claims. (Cl. 308-3) This invention relates to slide and way constructions and more particularly to a slideway construction which is capable of supporting a slide in any one of a number of adjustable positions and in such manner as to assure precise reciprocation of the slide without risking galling and without necessitating lubrication.
The invention is particularly applicable to electr1cal discharge or spark erosion machinery, but it 1s equally applicable to other kinds of machinery where an extremely true or precise mounting and reciprocation of a slide is required.
An object of this invention is to provide a slide and way construction which permits adjustment of the sl de and slide guideway in such manner as to locate the slide in any one of a number of adjustable POSI'EIOHS:
Another object of the invention is to provide a slide and way construction which employs selfcontained antigalling and lubricating means, thereby avoiding the necessity of providing exterior lubrication fitting and the necessity of periodic lubrications. I
A further object of the invention is to provide a slideway construction which is capable of being preloaded with relation to the slide mounted therein so as to preclude any possibility of lateral movement of the slide upon longitudinal reciprocation thereof.
Another object of the invention is to provide a sl deway construction which facilitates preloading of the slide.
Other objects and advantages of the invention Wlll be pointed out specifically or will become apparent from the following description when it is considered in conjunction with the appended claims and the accompanying drawing, wherein:
FIGURE 1 is a view, partly in end elevation and partly in section, of a slide and way assembly constructed in accordance with the invention, the section being taken on the line 11 of FIGURE 2;
FIGURE 2 is a view, partly in top plan and partly in section, of the apparatus, the section being taken on the line 2-2 of FIGURE 1; and
FIGURE 3 is a sectional, side elevational view of the slide mechanism, taken on the line 3-3 of FIGURE 1.
The apparatus is adapted for use with a base member 1 which may comprise the bed or a movable table of an electrical discharge or other machine, the base having a cavity 2 therein. The cavity has a pair of confronting, substantially parallel side walls 3 and 4 and aflat bottom 5. The base has an upper surface 6 provided with a number of upstanding support way surfaces 7 which may be ground to provide bearing surfaces for a movable table 8 or the like. Secured to the lower surface of the table 8 by suitable screws 9 or the like is a slide or key member 10 having smoothly finished, opposed side edges 11 and 12 which parallel the walls 3 and 4, respectively, of the cavity 2. The slide 10 also has a bottom surface 13 and a top surface 14 that is adapted to bear against the lower surface of the table 8. The slide 10 is preferably hollow and mounts a nut 15 at its rear end (FIGURE 3) which is provided with a threaded bore to accommodate a correspondingly threaded adjusting screw 16 that extends through and pro ects beyond both ends of the slide. Only the rear end of the screw 16 is threaded and the travel of the screw is such that the threaded portion never becomes exposed to the gritty electrolyte of the machine.
At each end of the adjusting screw 16 is a journal mem- 3,212,827 Patented Oct. 19, 1965 ice her 17 that is rotatably mounted by means of a thrust bearing assembly 18 which is supported in a bearing retainer 19 that is secured to a mounting ring 20 which may be bolted or otherwise suitably fixed at each end of the base 1. To one end of the shaft 16 is secured a hand wheel 21 that may be rotated by a handle 22 to effect rotation of the screw shaft 16. Inasmuch as the ends of the screw shaft 16 are fixed against longitudinal movement, rotation of the shaft in one direction or the other will cause movement of the slide 10 and the table 8 in one direction or the other.
Apparatus constructed in accordance with the invention includes a guideway 23 in which the slide 10 may be mounted for reciprocating movements. The guideway 23 comprises a first angle-shaped way member 24 having a pair of sections 25 and 26 arranged substantially normal to one another. The section 25 preferably includes a raised surface 27 on its inner face which is precision finished by grinding. The section 26 is provided with socket members 28 for the reception of bolts which may be received in openings or slots 2a formed in the base of the cavity 2 so as to position the member 24 at a desired location within the cavity 2.
Also forming part of the guideway 23 is a second way member 29 that is substantially planar and has a precision finished inner surface. The member 29 is arranged to parallel the section 25 so as to form with the latter and the section 26 a substantially U-shaped trough for the reception of the member 10. The way member 29 may be removably secured to the member 24 by suitable means such as screws 30 that are so located as to be received in threaded openings 31 formed in the flange 26. It is important to note that this method of forming the guideway provides a U-shaped way Whose interior side surfaces can be readily precision ground to size.
The close fitting of Way and slide surfaces of relatively movable members normally necessitates the provision of lubrication so as to minimize friction and its attendant consequences. However, if it is attempted to preload the way and slide members, antifriction members of an expensive nature must normally be used because such preloading squeezes out the lubrication so that galling results. In apparatus constructed according to the invention, a protective sheet 32 of about .015 inch in thickness is interposed between the slide 10 and each of the way members 25 and 29. Preferably, each member 32 is formed from a thermosetting resin having high thermal insulating properties and having inherent lubricating properties. Polymers of tetrafiuoroethylene, and particularly the polytetrafluoroethylene polymer known as Teflon, have been found to be satisfactory materials inasmuch as they are tough, highly slippery, and poor conductors of heat. Another plastic which may be suitable is polymononochlorotrifluoroethylene, which is known commercially as Kel-F. The members 32 are interposed between the slide and guide members in the form of sheets which are glued to the sides of the key member 10 with a commercially available epoxy adhesive. The members 32 prevent galling of the confronting surfaces of the slide and guideway, minimize the transfer of heat from one surface to another, and constitute rigid lubricating means, thereby avoiding the necessity of having to use other, more conventional forms of lubricants and fittings therefor.
The dimension a between the interior face of wall 25 and the end of section 26 in this preloaded assembly is greater than the width b of the key 10 with the sheets 32 applied. Accordingly, the overall width of key 10, including the sheets 32, will be substantially .0005 to .002 inch greater than the dimension a. The slideway 24 is provided with upper adjustable, non-yieldable, preloading screws 33 and 34 threaded into the members 25 and 29, respectively, in addition to the screws 30, and located in positions remote from the section 26. The screws 33 and 34 are adapted to be turned in such directions as to cause their heads to bear against the side walls 3 and 4 of the cavity 2 and react with the latter to force the way members 25 and 29 toward one another, thereby precisely locating the walls 25 and 29 and precluding any lateral movement of the slide relative to the slideway 24.
Regardless of the position of the slideway 24 in the cavity 2, the adjusting screws 33 and 34 are capable of adjustment suflicient to enable the way members 25 and 29 to be preloaded in the manner referred to above. Accordingly, the adjusting members 33 and 34 are capable of being utilized to eflect minor lateral adjustments of the slide 10 and, consequently, of the table 8.
The disclosed embodiment is representative of a presently prefered form of the invention but is intended to be illustrative, rather than definitive thereof. The invention is defined in the claims.
