Definitions

  • the present invention relates to work table adjusting mechanism for machine tools, and more particularly to mechanism for adjusting the positions of the work tables of copying or engraving or die-sinking machines or similar machines of the type employing two tables, one for holding a pattern to be followed and the other for holding apiece of work to be operated upon.
  • An object of the invention is the provision of simple and inexpensive mechanism by which each table may be individually adjusted in position, when so desired, and by which both tables may be concomitantly adjusted in position by the operation of a singleadjusting means such as a hand Wheel or crank, when so desired.
  • Another object of the invention is the provision of such mechanism in a form in which the conjoint operation of both tables does not interfere with individual adjustment of one table, so that both tables may be concomitantly adjusted when so desired, and then one of the tables'may be further adjusted individually without affecting the position of the other table.
  • Still another object is the provision of such mechanism in which the conjoint adjusting means may be rendered ineffective easily and quickly, with a minimum of eifort.
  • Fig. 1 is a front view of a machine in accordance with one embodiment of the present invention, partly in elevation and partly in vertical section;
  • Fig. 2 is a fragmentary vertical section taken substantially on the line II-II of Fig. 1, with parts in elevation;
  • Fig. 3 is a horizontal section taken approxi- .mately on the line III-III of Fig. 1;
  • Fig. 4 is a horizontal section taken approximately on the line IVIV of Fig. 1;
  • Fig. 5 is a view similar to Fig. 1, illustrating another embodiment of the invention.
  • the present invention obviates this, by enabling the two tables to be coupled to each other at will, so far as their adjustments are concerned, the coupling being in such a way that both tables may be moved concomitantly through identical amounts by the operation of a single adjusting means (for example, a hand wheel or crank) and yet this coupling of the tables to each other does not interfere with independent movement of one table relative to the other, whenever so desired.
  • the conjoint operating means of the present invention may quickly be rendered completely ineffective, leaving both tables to be adjusted entirely by their own independent adjusting means, whenever desired.
  • the main frame or pedestal of a suitable machine tool which, except for the table adjusting mechanism herein disclosed, may-be of any conventional or usual construction.
  • Mounted for vertical adjustment with respect to this main frame or pedestal l9 are the two tables l2 and M, the upper surfaces'of ,the tables having the usual T-shaped slots (Fig.
  • each table 12 and I4 may be independently raised and lowered by operation of its respective manual adjusting member 24 or 26. :But wheneverboth tables are to be adjusted vertically to exactly the same extent, considerable trouble and difficulty are frequently experienced, all of which is obviated by the present invention.
  • One side of the guideway 38 has a longitudinal slot or opening 54 to accommodate the upward 'an'ddo'wnwa'rd movements of the arm 52.
  • the first l6 cooperates in the conventional manner with.
  • this vertically movable nut 36 is an enlarged head or collar 42 which may rest on thetop oftheguiding sleeve or track 38 and thus determine the lowest position of the nut 36'and provide a support for the nut at this elevation, whenever itis not supported ata still t high'er elevation inithe manner described below.
  • a bracket '48 formed with a vertical journal or bearing 33 located between the two tables and relatively R'otatable in this the upper end of which is headed or enlarged so as to support the shaft against downward movement in the bracket.
  • the lower end of thisshait carries a laterallyextending'arm 52 which, when swungto the position shownin Fig. 4 and in the full lines in Fig. 1, has its 'end in a position directly alined with and underlying the lower end of the nut 36o1the second table it. seem inFigs.
  • the eiiective end of the As well arm 52 is formed of frusto-conical shape to engage with a hollow frusto-conical portion at the lower end of the .nut 36, to inter-lookone with the other and prevent :accidental lateral displacement of the supporting arm'from the nut when .the two are engaged with each other.
  • the adjustingmovement's of the work tables which may be coupled to each other-"in accordance witht'he present invention, are vertical or approximately vertical adjusting movements, as disclosed "above in the foregoing description referring toFigs. 1-4 of thedra'wings.
  • the present invention may be employed equally well for coupling together the adjusting movements of any two work tables which move through parallel or approximately parallel paths, regardless of whether these adjusting movements be'vertical or horizontal or at an oblique inclination,
  • Fig. '5 a machine in which the work'tables are movable horizontally, the structure being substantially the same as shown in Figs. 1 to 4 except for be- -ing turned, as it were, on its" side.
  • the corresponding parts in'Fig. 5 are given the same -reference numerals as in Figs. 1-4 with the addition "of Hill to each numeral.
  • a strong spring is tends'constantly to draw the second table I '34, I it to the right when viewed as in Fig.5, keeping the nut member of this table always engaged either with the connecting member l52, when the latter is in proper position for engaging the nut, or with the supporting member I38 which serves as alimit stop or abutment for the nut member I36 when the connecting member I52 is not in position to engage the nut member.
  • a motor I64 for driving the cutting tool
  • this construction diagrammatically illustrated in Fig. 5 may be the same as the construction previously described in connection with Figs. 1-4, and it operates in the same way and has the same advantages.
  • a machine tool including a first work table mounted for adjusting movement, a second work table also mounted for adjusting movement, first adjusting means for varying the position of said first work table, second adjusting means for varying the position of said second work table, and interconnecting means operatively connected to said first work table and movable bodily therewith and also movable relative to said first work table from an ineifective position uncoupled from said second table to an effective operating position engaging with a portion of said second adjusting means for causing said second table to move through its adjusting movements concomitantly with the adjusting movements of said first table.
  • said second adjusting means includes cooperating screw and nut parts, and in which said interconnecting means, when in its operative position, engages with and acts as a position-determining member for one of said parts.
  • said interconnecting means is in the form of a shiftable arm mounted to move bodily with said first table and also mounted for shifting movement in a direction laterally with respect to the direction of adjusting movement of said first table, from an effective position wherein a portion of said arm is alined with a portion of said nut part in a position to engage with and cause movement of said nut part, to an ineffective position out of alinement with said nut part.
