Definitions

  • Headstocks of this nature are already known which consist of one piece; These headstocks are made as hollow columns and they are fitted over the guide columns. To move the headstock with respect to the column, there have been-used in these cases ball bearings the outer annular surfaces of which slid along on guide surfaces provided on the guide column. These ball bearings present no complete assurance of an exact guidance of the headstock, since the latter can take up an inclined adjusting position on account of inaccurate adjustment of the ball bearings or on account of the ball bearing rings yielding flexibly, so that there is no rigid and firm adjustment.
  • the present invention obviates this disadvantage and provides a guide which at all times and even if an adjustment has taken place, permits an exact movement in the desired plane.
  • FIG. 1 shows a section through the guide column with the headstock on the line l-l' of Figure 2;
  • Figure 2 is a cross-section through Figure l on the line 2-2;
  • Figure 3 shows in detail on a larger scale a slide block in side view
  • Figure 4 shows a plan view of a slide block.
  • a is the vertical guide column for the headstock of a surface grinding machine.
  • guide surfaces machined on the'four corners and extending in strip form from the top to the bottom, which guide surfaces are indicated by the reference letter 1), with the exception of the two surfaces at the back of the'column which are indicated by i the reference letter 0.
  • These latter surfaces are exactly perpendicular to the grinding spindle axis and exactly parallel to the direction of movement of the work table.
  • the actual headstock which consists of a closed hollow four- 1 cornered body 01 is fitted round the column. This body has on the front the bearing e for the grinding spindle and on the back the driving motor 9 for the grinding spindle.
  • Slide blocks h and i serve for guiding the headstock.
  • the slide blocks h are provided on the front and on the two side surfaces, their shape is shown on'an enlarged scale in Figure 3. They are simple guide plates which are held against the guide surfaces 1) by means of screws is, which are screwed through the headstock.
  • the headstock is provided on the outside with exact control surfaces n preferably located in the same plane; and from which the whole machining of the headstock takes place, and which after the mounting of the headstock in the machine lie exactly parallel to the surfaces 0, that is, exactly perpendicularly to the grinding spindle axis and parallel to the direction of movement of the headstock.
  • the slide blocks i are provided with a widened head 0 and are inserted from the outside through holes in the headstock.
  • the inner surfaces of the head here bear against the control surfaces 1;. whilst the end surfaces projecting inwardly of the blocks bear against the sliding surfaces 0.
  • the fixing of the blocks 2' on the headstock can take place in any desired manner, e. g., by screws or the like.
  • the sliding blocks h and z are provided in at least two rows over each other in order to ensure correct guiding.
  • the blocks h are freely movable on the screws k: and the slide blocks of the upper group have a Z-shaped lubricating groove m, which is open at the top and bottom. Owing to the shape of these grooves, the oil intended for the upper slide blocks is kept therein and only the superfluous oil flows .down to the lower slide blocks.
  • the slide blocks 12 are not tightened but form the permanent support of the headstock onthe slide surfaces 0, so that as these slide surfaces and the thickness of the slide blocks are exactly produced from the outset, the guiding of the headstock always remains unaltered even when in consequence of wear or the like an adjustment of the other slide blocks It takes place by means of the screws is.
  • the guide column is shown four-cornered, but naturally any other desired cross-sectional form may be chosen, e. g., a round, elliptical or polygonal one, and in the same way the sliding blocks if desired can be arranged superposed in more than two rows.
  • a headstock comprising a homogeneous hollow body, a spindle journalled in said headstock, a guide column embraced by said headstock, control surfaces provided on an outer side of the headstock located parallel to the movement of the headstock and arranged exactly with respect to the spindle axis, and guide elements bearing against said surfaces, said guide elements projecting into the interior of the headstock and engage said guide column.
  • a headstock comprising a homogeneous hollow body, a spindle journalled in said headstock, a guide column embraced by said headstock, control surfaces provided on an outer side of the headstock located parallel to the movement of the headstock and arranged exactly with respect to the spindle axis, guiding surfaces provided on said guide column and guide elements bearing against said control surfaces, said guide elements projecting into the interior of the headstock and engaging said guiding surfaces.

  • a headstock comprising a homogeneous hollow body, a spindle journalled in said headstock, a guide column embraced by said headstock, control surfaces provided on an outer side of the headstock located parallel to the movement of the headstock and arranged exactly with respect to the spindle axis, and slide blocks provided in the headstock and projecting entirely through a side Wall of the headstock from the outside into the interior thereof, each block bearing against a control surface and also engages the guide column.
  • a headstock in combination, a headstock, a guide column embraced by said headstock, said headstock having control surfaces provided on, an outer side of the headstock, and guide elements provided in said headstock from the outside into the interior thereof and bearing against said control surfaces, said guide elements also engaging said guide column.
