Definitions

  • the invention relates to a finishing road with a workpiece slide displaceable intermittently along a straight guide and with at least one machine tool bed located at every machining station perpendicularly to the road and adapted to receive one machining or processing unit.
  • finishing roads are nowadays only suitable for large series of uniform parts and desirable modifications have often to be abandoned, owing to the extensive and expensive rearrangement of the finishing road which would be necessary.
  • the present invention aims at eliminating these drawbacks and at providing a universal finishing road suitable also for smaller series, making possible a change in the. production programme and in the machining units with their beds quickly and with a minimum of expediture.
  • this object is realized in that the guide for the workpiece slide consists of longitudinal sections, each associated with one of the adjacent machines and comprising the necessary centering and clamping points for the slide, whilst all machine tool beds are located and easily detachably mounted on a profiled bar or the like, forming part of the finishing road.
  • each section of the guide is rigidly connected with a pair of machine beds with the such beds located on opposite sides of the guide, each such pair of machine beds being guided and located by means of two parallel profiled bars of the finishing road.
  • the' successive supports of the finishing road are detachably connected also in their lower zones. This results in an extraordinarily rigid bed for the entire installation which no longer requires special foundations.
  • An existing finishing road may be easily shortened or extended if a new programme requires less or more operations than the previous one.
  • FIG. 1 shows the finishing road according to the invention in diagrammatic side elevation
  • FIG. 2 is a cross-section of the road of FIG. 1 along the line IIII (showing only the parts visible along this cross-section, the road being slightly modified compared number of pairs of machine tool beds 3' which may be fitted on these profiled bars 2 by means of grooves 3 and connected by bolts with the supports 1.
  • the first (starting) support and the last (finishing) support 1 have also special, similarly fixed machine beds 4 and 5; the machine bed 4 carries also a hydraulic installation, not shown in detail, for the workpiece advance, as explained in detail fiurther below and an associated electrical control apparatus 6, whilst the machine tool bed 5 carries a shock-absorber 7, adapted to receive the workpiece (not shown) arriving at the end of the finishing road.
  • each pair or machine beds :3 has two opposite machine beds 3n and 3b, between which there is located along the lateral centre plane of the pair otmachine beds and thus along the vertical longitudinal centre plane of the road, a
  • a vertically displaceable indexing pin is mounted along the vertical centre lines of the guide and of the entire pair of machine beds, and two clamping jaws 11 are provided in the, longitudinal direction of the pair of machine. beds 3 in appropriate recesses of the two guides 8, so that they may be moved downwards from their.

  • Each-pair 3 of machine: beds may be bolted together with the associated support 1 on both sides of the pro filed bar 2 by means of screws or bolts 13.
  • the successive supports 1 are detaohably connected one tothe other in their lower zones at the points 14 (FIG; 1) by means not shown in detail.
  • pairs 3 of machine bed-s are bolted together by connections 15, as shown in FIG. 4; these connections maybe disconnected simply when a pair of beds has to be ex-;
  • a horizontal conveyor chain 16 is located in lower recesses of the support 1, extending between the first and last support 1 and serving to return the workpiece slide 9,
  • a space corresponding substantially to one processing sta tion is left tree between the, first and second, and between the penultimate and last supports 1, bridged merely by thev profiled bars 2 andat the'bottom by the connections 175
  • the first support 1 is equipped with a car? riage 19 vertically displaceable in a guide 18, and a similar vertical guide 20 with a further carriageZl isl-ocated on the last support; these two carriages are vertically displaceable between there upper position (FIG. 1) and a.
  • the hydraulic installation in the machine bed 4 serves also for supplying a forwarding cylinder 22 in which a forwarding piston (not shown) is displaceable by an amount corresponding to the length of one processing step in the direction of the movement of the workpiece slidei
  • This hydraulic installation is also used for operating the indexing pins 10* and the clamping jaws 11 in accordance with the programming of the control device 6, through.
  • conduits provided in the machine beds 3 and through conduits 23 connecting the pairs of machine beds 3 see FIG. 1
  • machining units (not shown) are mounted on the individual machine beds 3a.

  • This shock absorber forms simultaneously a stop by means I of which the succeeding, abnttingcarriages. 9"are held at their respective processing .stations'with vsutlicient .accuracy.
  • the exact alignment of the workpiece carriages 9' at the individual processing stations is ettected by means of the indexing/pins 10' which aremoved 'by-the' control mechanism 6 and the hydra ulicqinstallation slightlytowards the top and engage: into conical bores (not shown) of t-heL WOIkpiececarriages 9, located above .them.: During the.
  • the clamping jaws associated: with each pair 3 otmachinebeds are moved downwardly and the centered carriage '9 isjnow firmly clamped against theguides 8 of the pair 3 of machine beds- After this clamping, the control mechanismfi issues a further impulse whereby the operation of the machining units located on the tool carriagesila and 3b is initiated.

  • the workpiece may again be again as described before. machined or processed fromboth sides and this action continues. until itireaches, in its turn, with its carriage 9 5 the carriage 21; Here it is'detached from the workpiece slide 9'during, the machining of. the next part and the empty workpiece carrier travels with the carriage 21 in a downward direction and is deposited 'on the conveyor chain; .the conveyor chain transports this slide 9 again tov the starting point where it is received by the carriagev 19 z This carriage 19 lifts the empty workpiece carrier 9 to the top and the which is now in its bottommost position.
