Definitions

  • the holes to be drilled are distributed at uniform intervals either along a single line or along parallel lines, themselves disposed at a given interval from one another, the holes being, as a rule, off-set alternately from one line of holes to the next one, in such manner as to obtain a staggered arrangement.
  • the present invention relates to machines in which two parts are to be given a series of relative positions, such as above mentioned, and it is particularly applicable to drilling machines and more especially, although not exclusively, radial drilling machines.
  • the chief object of the present invention is to provide a machine of this kind which is better adapted to meet the requirements of actual practice and in particular avoids the above mentioned drawbacks, to wit the necessity of plotting and starting all the holes to be drilled.
  • Another object of the presentinvention is to accelerate the drilling of holes located along straight lines by eliminating the necessity of special bit centering operations.
  • Still another object of the present invention is to ensure a better accuracy of the work that is obtained by eliminating the possibility of mistake in the positioning of the bit.
  • I provide means for guiding the relative displacement of the bit carriage with respect to the piece of work, and automatically gtopping and maintaining said carriage along its path of travel, at predetermined intervals which may be given different values.
  • these means include a rule or rod, arranged, in the case of a radial drilling machine, parallel to the arm thereof, that is to say along the path of displacement of the carriage which carries the bit or drill, and cooperatgage, in the course of the displacement of the rule at intervals corresponding to the spacing to be obtained between the respective holes to be drilled into the piece of work.
  • the distance between the successive lines of holes may be indicated by a mark made on the piece of work, or, according to an embodiment of the invention, a second rule used in combination with the first is placed at right angles to said first mentioned rule and it is rigid with the table that supports the piece of work. Or, according to another possible arrangement, the whole of the drilling machine is movable with respect to the piece of work, which is held stationary, and the second mentioned rule is fixed with respect to the track along which said movable drilling machine can be displaced.
  • This second rule which is provided with holes or recesses provided it predetermined intervals from one another, corresponding to the distances to exist between the respective lines of holes, thus ensure the holding of the drill or hit along each of said lines.
  • said rule or each of said rules, is of polygonal section, each of the faces thereof being provided with holes or recesses disposed at a given interval from one another or according to a predetermined law, whereby a very small number of rules is sufilcient for ensuring all the spacings that are commonly used in boiler work or the like. It sufliccs, in order to obtain the desired spacing, to turn the rule about its longitudinal axis, so as to bring the face corresponding to this spacing opposite the elastic stop or equivalent means.
  • the rule can be fixed in its supports in either of two difierent longitudinal positions, corresponding to the oil-setting to be obtained between the stoppage positions of the carriage from one line to the other in order automatically to obtain a staggered relation of the holes inthe piece of work.
  • This accuracy can be still further improved by providing the tool supporting carriage with a device for guiding the drill or bit with a view to avoiding any slipping of said drill or bit with respect to the piece of work at the beginning of the drilling operation.
  • This last mentioned device further reduces the risks of breaking the drill or bit.
  • Fig. 1 is a general elevational view of a radial drilling machine made according to the present invention and including means for automatically stopping the tool supporting carriage and the movable table which carries the piece of work;
  • Fig. 2 is a plan view of the radial drilling machine of Fig. 1;
  • Fig. 3 is a general elevational view of a radial drilling machine having a movable column and a stationary table, in which the second stopping means used in combination with the means for stopping the tool supporting carriage determines the position of the whole of the movable part with respect to the track along which it can be displaced;
  • Fig. 4 is a detail view, on an enlarged scale, of the arm of the drilling machine according to the invention.

  • Fig. 8 is an elevational view, partly in section, showing the arrangement of the drill guiding device
  • Fig. 9 is a plan view of the device shown by Fig. 8.
  • the arm I of the drilling machine is provided with a hexagonal rule 2, which cooperates with the stopp and locking means carried by the part II of the tool supporting carnage.
  • the base of the movable table of the machine is provided with a similar rule 2', disposed at right angles to the first, while the table itself is fitted with a support II on which is fixed the stopping and locking means which cooperates with rule 2'.
  • the column is movable along rails, whereas the table is stationary.
  • the second rule that is to say that which serves to control the distances between the rows of holes, is fixed on one of the rails, and the stopping and locking means is fixed to the corresponding longitudinal member of the machine.
  • rule 2 constituted by a hexagonal steel bar, provided, along the central line of each of its faces, with holes or recesses 3 located either at regular intervals from one another or according to any predetermined law, is fixed to the arm I of the drilling machine.
  • intervals which are different along each of the six faces, corresponding to the various spacings with which the holes are to be drilled in the piece of work, so that, with a single rule, it is possible to obtain six different spacings.
  • Rule 2 is guided at each endthereof by bear- These bearin s enable the rule to move with an axial displacement equal to at least one. half of the maximum spacing of the holes.
  • Rule 2 can turn freely about its axis in the bearings la and 4b by which it 'islsupported, whereby any of its six faces can be brought opposite the elastic stop i. It is locked in any of these six positions by the engagement of said stop 8 in one of the six cylindrical holes or housings I provided in the rule.
  • another identical housing 8 is provided, at a distance from the corresponding housing I, e being the interval between the consecutive holes of the face of the rule that is considered.
  • Finger 8 which is rigid with a milled knob I3, is screwed in a supporting piece 9 itself slidably supported by bearing to. The locking of supporting piece I in suitable position with respect to bearing 4a is ensured by bolt It.
  • a support II which carries a stop pin I 2 constantly urged by a spring against the vertical face of the rule.
  • this stop pin l2 engages into the first cylindrical housing 3 to come across its way, and it stops carriage I. It can be disengaged from said housing by pulling it by means of milled knob I. By pulling this knob rearwardly and turning it through lug l5 keeps it in the rear position and the stopping pin is rendered inoperative, thus permitting a quick displacement of carriage I along its guide, opposite arm I.
  • This drill guiding device is fixed to the lower part of the tool supporting carriage by means of support It, which is fitted with a guide bar i'l adapted to be adjusted at any desired height.
  • a suitable support it which is capable of moving along the guide bar, carries a ring it for centering the drill or bit.
  • This ring is mounted in a ball or roller bearing, so that it can turn together with the drill or bit without producing any detrimental friction.
  • Ring is adaptable to various sizes of the holes to be drilled.
  • the guide bar I! and the adjustable support i8 are locked in position by means of nuts 20 which hold collar halves 2
  • the square cross-section of bar l1 ensures a guiding of the drill at all heights of utilization, and also a considerable rigidity of the whole guiding device.
  • a metal sheet 20 is to be provided with holes disposed as shown by Fig. 7, an arrangement which is common in boiler-work.
  • the metal sheet is secured to a roller support so that it can be displaced perpendicularly to the path of travel of the carriage, the successive lines of holes remaining parallel to this path of cally giving the ofisetting e of each line of holes.
  • the carriage is free on its slideway.
  • the rule is turned about its longitudinal axis in such manner as to bring face 20, the housings 3 )f which are located at a distance e from one another equal to the desired spacing of the hole to be drilled, frontward, in vertical position, and it is locked in this position by screwing the flnger 6 through the milled knob l3.
  • the elastic stopping pin I2 is engaged into a housing 3. chosen in such manner that there remains a sufflcient margin of displacement of the carriage for permitting ofbringing it from one end to the other of the width 1 of the metal sheet 20. Care should be taken to place this sheet -n such manner that the first hole a is approximately centered with respect to the drill or bit.
  • Bolt or screw 10 is loosened, and the carriage is displaced in the direction indicated by arrows f or P. It drives rule 2 together with itself. At the same time, the metal sheet is moved in the perpendicular direction (arrow f or F) so as accurately to center the drill or hit for the drilling of the first hole a.
  • the metal sheet is first displaced parallel to itself (arrow until the point of the drill or bit comes on the second line of holes (which need be plotted or traced only in portion AB). Finger 6 is then unscrewed by means of knob l3, and, bolt l0 remaining tightened, rule 2 is displaced so that finger 6 engages into hole 8. The rule is then fixed in this position by means of knob 13. The rule has thus been displaced a distance equal to one half of the interval between two consecutive holes, so that I directly obtain the staggered arrangement of the holes of the second line with respect to those of the first line, without it being necessary to lay outor plot the holes.
  • the drilling process is the same as for the first line, the first holeto be drilled being hole d. Then the third line is drilled, by bringing back finger 6 into hole I. And so on for the other lines of holes to be drilled.
  • the means for displacing the metal sheet may be fitted with an analogous device automati-
  • the rule provided with the holes or recesses corresponding to the respective lines of holes is then arranged in a direction at right angles to that of the rule 2 which automatically stops the carriage for the drilling of the successive holes.
  • This arrangement can also be utilized when the drilling machine is movable with respect to the piece of work and the latter is held stationary. By making use of this combination of two rules, it then suflices, in order to drill a plurality of holes as shown by the drawings, to trace or plot the first hole and to mark the last line of drilling.
  • the distance between the holes or recesses I and 8 of the rule, which, in the example illustrated, is equal to can be given any other value. Also, while value e has been assumed to be constant, it can vary according to any predetermined law, if this is necessary or advantageous.
  • the cross section of the rule instead of being hexagonal, may be chosen of any desired shape with a greater or lower number of sides, according as the case may be.
