Definitions

  • Patent 3,366,426 ALIGNMENT G s Krau Traunreut Upper avarla, ermany, a s i gflor to Firma Wenzler & Heidenhain, Traunreut,
  • the present invention relates to an alignment guide, in general, and to an apparatus for guid ng a member, for instance a tool or the like, along a guide path of a gulde body, in which the weight of the member 18 assumed by a carrying path and the member carrier engages the guidth in articular.
  • the tool holder is supposed to be moved linearly as much as possible 1n the direction of the line to be formed, whereby particularly the deviations to the right or the left from the prescribed moving path are to be avoided.
  • the apparatus is designed such that the carrier of the tool, which is connected with a round guide by means of levers and a guide system, has the possibility to swing about the median axis of the round guide, and in particular up to the abutment of a slide shoe, secured laterally on the lever, on the reference face of an optical face body.
  • the slide shoe does not engage the reference face of the face body by means of a point, rather its engaging face has a rectangular cross-section.
  • the coarse guide comprises a slide guide in a groove on two sides, which slide has a rectangular opening extending from its upper side to its lower side, through which opening extends a slide shoe with play.
  • the slide shoe is equipped with three projections which engage their own guide path and which prevent any edging or tipping of the slide shoe relative to this guide path.
  • the slide shoe is urged towards the guide path by means of springs which are supported on the mentioned slide.
  • the slide of the coarse guide system constitutes simultaneously the drive element, so that the longitudinal movements accorded to the slide are transmitted to the slide shoe.
  • the slide can be moved relative to the slide shoe, whereby it does Patented Jan. 30, 1968 not transmit any of its deviation movements to the slide shoe.
  • the movement plane of the slide shoe connected with the tool is thus produced exclusively by the projections of the slide shoe engaging the guide path.
  • the drawback resides, however, the same as in the first described apparatus, that due to the one-sided pressure force of the slide shoe onto the guide path, which is brought about by spring elements, the guide path is deformed crosswise to the prescribed movement path due to occurring bending moments.
  • FIGURE 1 is a section of the alignment guide designed in accordance with the present invention.
  • FIG. 2 is a section along the lines 22 of FIG. 1;
  • FIG. 3 is a section along the lines 3-3 of FIG. 1.
  • the alignment guide comprises a displaceable member 1, which is movable by means (not shown), for instance, by a threaded spindle or the like, perpendicularly to the sheet of the drawings of FIG. 1.
  • the weight of the member 1 is taken up, as is shown in FIGS. 2 and 3, by means of rollers 5, 6 and 7 on a supporting path 8, which rollers 5, 6 and 7 are secured to the member 1 by means of bearings 2, 3 and 4.
  • the supporting path 8 rests at its ends, as shown in FIG. 2, on supporting bodies 9 and 10 by means of a three-point support (not shown), whereby the weight load of the member 1, which is assumed by the supporting path 8, is fed by means of the supporting bodies 9 and 10 to a foundation (not shown).
  • the supporting path 8 is deformed due to the occurring bending moments by the weight of the member 1, since the supporting path 8 is freely carrying between the supporting bodies 9 and 10 and in particular the carrying path 8 is deformed such, that the member 1 is subjected to a deviation movement, which is perpendicular to the movement of direction. It is, however, not the aim of the present invention to compensate for the mentioned deviation movement. It is the aim of the present invention, as has been stated above, to assign to a member secured to a carrier 13 in its moving direction a movement parallel to a guide path 12 of a guide body 11.
  • the guide body 11 includes a second path or face 30 on the side of the guide body 11 opposite the guide path 12.
  • the fork-shaped member 1 surrounds the guide body 11, and includes a first side 1a and a second side 1b, respectively, extending adjacent and in spaced relationship relative to the guide path 12 and the second path 30, respectively of the guide body 11.
  • the member carrier 13 is supported on the supporting path 8 by means of rollers 15 and 16.
  • the supporting path 8 is, as can be ascertained from FIG. 1, equipped with a groove 8', so that the member carrier 13 projects through the supporting path 8 without contacting the latter.
  • the member carrier 13 has itself, as shown in FIGS. 1 and 2, likewise a rectangular opening 13', so that the bearing 4 secured to the member 1 can project through the member carrier 1 without engaging the same.
  • the member carrier 13 is brought into engagement with the guide path 12 of the guide body 11, as shown in FIGS. 1 and 2, by means of slide shoes 17, 18 and 19 by means of a pretensioned catch 22, which can be secured by a nut 21.
  • the catch 22 is formed in the present embodiment as a resilient three-armed spring blade.
  • the catch 22 is secured to one side of a part 23, and the other side of the part 23 is equipped with a groove of V-shaped cross-section.
  • the part 23 is connected with a part 1 by means of a ball 24 guided in the V-shaped groove and centered in the threaded bolt 20. Since upon turning the screw bolt 21 the catch 22 is subjected to a change of its length due to its displacement, it is connected with the member carrier 13 by means of projections 25, 26 and 27 guided in V-shaped grooves and secured to the catch 22.
  • the projections 25, 26 and 27 of the catch 22 which engage the V-shaped grooves constitute simultaneously the coupling between the member 1 and the member carrier 13, that means the longitudinal movements applied to the member 1 are transmitted to the member carrier 13 by means of the catch 22.
  • the screw bolt 21 ⁇ , nut 21, part 23, catch 22, projections 25, 26 and 27, ball 24 and the mountings therebetween, constitute a first pressure means.
  • a counter-pressure element 14 is disposed between the second side 1b of the member 1 and the second path on face 30 of the guide body 12 and aligned relative to the member carrier 13 such that the engaging points of rollers 31, 32 and 33 on the second path 30 of the guide body 11, as well as the engaging points of the slides'hoes 17, 18 and 19 on th guide path 12 of the guide body 11, as well as substantially the engaging points of the projections 25, 26 and 27 of the catch 22 in the V-shaped grooves in the carrier member 13, are disposed always on a linear line parallel to the direction of pressure.
  • the counter-pressure element 14 is maintained as shown in FIGS. 1 and 3 in position by means of the screws 34 and 35 secured to the second side 1b of the member 1.
  • connection between the screws 4 and 35 and the counter-pressure element 14 is flexible by means of balls 36 and 37 centered in the screws 34 and 35.
  • the guide body 11 is connected with the base plate 38, which has no connection with the carriers 9 and 10.
  • the screws 34 and 35, balls 36 and 37 and the mountings there'between constitute a second pressure means.
  • the member secured to the carrier 13 is subjected to a movement corresponding to the linearity of the guide path 12.
  • An apparatus for guiding a member along a stationary guide path of a guid body comprising,
  • a longitudinal guide body having opposite longitudinal surfaces defining a first guide surface and a second guide surface, respectively,
  • said supporting guide surface being disposed independent from said guide surface of said guide body
  • first selectively adjustable pressure means connected to said first side of said generally U-shaped member for pressing said member carrier against said first guide surface
  • a counter-pressure element disposed between said second side of said generally U-shaped member and said second guide surface of said guide body, second pressure means connected to said second side of said generally U-shaped member for pressing said counter pressure element against said second guide surface of said guide body, said member carrier and said counter-pressure element and said first and second pressure means aligned to apply pressure from opposite sides to said guide body 2.
  • said counter-pressure element and said member carrier are pressing against said first guide surface and second guide surface, respectively, and said first pressure means are pressing against said member carrier, at engaging points
  • said engaging points between said first pressure means and said member carrier as well as between said member carrier and said first guide surface, and between said counter-pressure element and said second guide surface are disposed on a line parallel to the direction of the pressure of said pressing.
  • said first pressure means includes a threaded bolt and nut combination secured to said first side of said member
  • said resilient member comprises a spring blade catch means including radial arm portions for pressing against said member carrier,
  • said spring blade catch means includes projections on said arm portions facing said member carrier,
  • said member carrier having groove means in which said projections are slidably mounted for expansion of said spring blade catch means, and i a ball disposed in a V-shaped ball joint groove between the end of said threaded bolt and the middle of said spring blade catch means.
  • said member carrier having an opening adjacent said sup-port path between said at least two longitudinally spaced first roller means
  • said member is fork-shaped and transversely surrounds said guide body.
