Definitions

  • the present invention relates generally to an apparatus for removing material from a workpiece, and more particularly to such an apparatus which includes an arrangement for the dry lubrication of the materialremoval tool of the apparatus.
  • Such considerations are applicable not only to grinding wheels or similar instrumentalities, but also for other rotating material-removal tools such as circular saws and milling tools whose material-removal faces or edges may be of hard metal, steel, abrasive particles and the like.
  • a still more particularly object of the invention is to provide such an arrangement in which a body of solid lubricant can be employed for lubricating purposes, and in which the frequently rather expensive solid lubricant it can be precisely needed onto the tool.
  • Another object of the invention is to provide such an arrangement permitting the utilization of a body of solid lubricant of relatively large volume without, however, having to resort to imparting to the body reciprocatory or other movements to assure even Waring-away of the body.
  • an apparatus for removing material from a workpiece in a combination which, briefly stated, comprises a rotary tool having a materialremoving face, and first rotating means for rotating this too] about a first axis and at a first speed.
  • a body of solid lubricant is located axially adjacent the materialremoving face of the tool and second rotating means is provided for rotating the body about a second axis and at a slower second speed.
  • Advancing means effects advancement of the first axis against rotary body of solid lubricant longitudinally of the first axis against the material-removing face of the tool.
  • the drive of the body of solid lubricant can be effected intermittently, that is if it can be interrupted if and when the drive is not required. For instance, interruption can be programmed to take place automatically during times during which the rotary tool is not in engagement with a workpiece. This avoids an unnecessary development of dust and an unnecessary waringaway of the lubricant, increasing the economy of utilization of solid lubricants substantially. This is especially important if the lubricant substance or substances of a body of solid lubricant are constituted on one of the more expensive types of materials, such as hexagonal boron nitride or molybdenum disulfide.
  • the invention makes possible, as already pointed out earlier, the use of solid lubricant bodies of relatively large volume.
  • the reason for this is that in an arrangement according to the present invention the solid lubricant body can be configurated as a disk or as an annu lus of relatively large diameter. This means that the amount of lubricant available in a central body is rather large, so that when such body has been first put in use it can last for a significant period of time, making it unnecessary to interrupt any operation of the rotary tool for the frequent replacement of the body of solid lubricant.
  • such bodies of solid lubricant can be used for lubricating even rotarytools havinga narrow material-removal face, achieving an even wearing-away of the lubricant without having to effect transverse movement of the body of solid lubricant relative to the material-removal face.
  • the drive of the body of solid lubricant can be effected via a small gear motor. and generally speaking a small electro motor will be sufficient. However, it is possible to use pneumatic or'hydraulic drives, or to provide a'mechanical transmission of motor power from the drive there employed for rotating the rotary tool itself.
  • FIG. 1 is a fragmentary diagrammatic sectional illustration of one embodiment of the invention
  • FIG. 2 is a top-plan view of FIG. 1;
  • FIG. 3 is a view similar to FIG. 1 but illustrating a further embodiment of the invention on an enlarged scale;
  • reference numeral 1 identifies a substantially cup-shaped rotary material-removing tool.
  • This tool is not novel per se and tools of this type are used in apparatus for removing material from a workpiece.
  • the tool 1 is mounted on the driven shaft 2, which for purposes of the present discussion will be considered the rotating or drive means for the tool 1.
  • the shaft 2 must itself be rotated which can be accomplished in any known manner requiring no detailed discussion.
  • the shaft 2 is rotated in the direction of the curved arrow 3 and the annular material-removal face 4 at the righthand axial end (in FIG. 1 and FIG. 2) of the tool 1 is brought into engagement with the workpiece 5 from which material is to be removed.
  • the workpiece 5 is usually advanced into contact with the face 4, but this also is of no consequence for the purposes of the present invention.
  • a body 6 of solid lubricant here of annular configuration.
  • the body 6 is mounted on a shaft 7 which for purposes of the present discussion is also to be considered the rotating means for rotating the body 6 of the solid lubricant.
  • the shaft 7 rotates in the direction of the curved arrow associated with it, and is additionally during such rotation advanced in the direction of the arrow 8 (see'FIG. I) so as to contact the face 4.
  • the body 6 may be at least in part of molybdenum disulfide, hexagonal boron nitride or graphitic material, or combinations of these materials.
  • the longitudinal axis of the shafts 2 and 7 are inclined with reference to one another, forming an angle of divergen'ce a which is shown in FIG. 2.
  • This angle is small and the inclination has been found to be advantageous if the removing of material from the workpiece 5 takes place while the workpiece is moved to and fro with ref erence to the-tool 1, because in this type of material removing operation there is a relatively high transmission of forces to the face 4 which must therefore be well and predominantly lubricated. This is possible when the axes are inclined relative to one another at the angle a as illustrated.
  • a contact arm 10 Located above the shaft 7 (as seen with reference to FIG. 1) and engaging the reverse side of the lubricant body 6, that is the axial side which faces in the direction of advancement indicated by the arrow 8, is a contact arm 10 having the illustrated roller and engaging the adjacent axial end of the lubricant body 6.
  • the location where the arm 10 or the roller thereof engages the body 6 is located behind the general place of the contact face 4, that is to the left of that general plane, with the term behind referring to the fact that the location is beyond the general'plane as the material-removal face 4 as seen in the direction of the arrow 8. This assures a removal of lubricant from the solid lubricant body 6 in spiral streaks.
  • the tool 1 may be rotated at approximately 4000 rpm.
  • the rotation of the body 6 can be effected at only approximately 12 rotations per hour.
  • the differential size relationships of the lubri cant body 6 on the one hand, which may have an outer diameter of approximately 60 millimeters and an inner diameter of approximately 40 millimeters in the embodiment of FIGS.
  • the lubricant body 6 with its shaft 7 does not extend entirely in parallelism with the shaft 2 of the tool 1.
  • the rear or right-hand axial end of the lubricant body 6 will be inclined somewhat with reference to the shaft 2, but in this embodiment it will be found outwardly of the plane of the Figure by a small amount.
  • Reference numeral 1 identifies a material-removal tool which, however, is here illustrated as a disk rotating in the direction of the arrow 3. Adjacent the periphery of the disk which periphery here has the materialremoving face, there is again located a body 6 of solid lubricant. It is mounted on the shaft 7 which rotates in direction of the arrow 12.
  • Reference character M designates diagrammatically a drive motor for the shaft 12 and reference numeral 13 identifies an advancing device which is capable of advancing the shaft 7 and the body 6 axially of itself, that is into engagement with the material-removing face of the tool 1.
  • the device 13 may be provided with a threaded guidance arrangement which will be described subsequently and which provides the desired advancement towards the tool 1.
  • FIG. 5 we have illustrated an embodiment in which the body 6 of solid lubricant is again advanced in the direction of the arrow 8 towardsthe circumferential edge face of the tool 1, in direction normal to the elongation of the shaft 2 and with the shaft 7 extending in parallelism with the shaft 2.
  • This arrangement is particularly suitable for lubricating disk-shaped tools having a profiled circumferential edge. face as shown in FIG. 5.
  • FIGS. 6 and 7 finally, illustrate two embodiments which are exemplary of arrangements for advancing the body 6 into engagement with the material-removing face of the tool.
  • FIG. 6 it will be seen that the body 6 is mounted on the shaft 7 as before.
  • the mounting is effected via an intermediary, via the carrier 14 which may be of one piece with or separate from the shaft 7,
  • a tube 15 is provided into which the shaft 7 extends and in which the shaft 7 is axially displaceable (in telescope fashion) against the biassing action of a helical spring 16.
  • the rear-end portion (the end portion remote from the body 6) is provided with two grooves 17 and 18 for which a transverse pin 19 extends, which also passes through an appropriate passage provided in the turning end portion of the shaft 7.
  • the helical spring 19 surrounds the shaft 7 in part and engages with one of its ends the end portions of the pin 19 which extend outwardly beyond the shaft, whereas the other end of the spring abuts a collar 20 at the front or left-end of the tube 15.
  • This is in form of a sleeve 23 which is connected with an end portion 22 of the tube 15 and is provided with radial bores or passages 24.
  • a member 25 is accommodated in the sleeve 23, being fixedly connected with the output shaft 21 of the motor M, and being provided with a bore 26 in which there is located a spherical member 28 which is being urged outwardly of the bore by the pressure of a spring 27.
  • the spherical element 28 extends in part into a bore 24, thus coupling the elements 15 and 21 for joint rotation.
  • the circle element 28 will be inwardly displaced out of the bore 24 and the shaft 7 will be uncoupled from the shaft 21.
  • a contact arm 10 engaging the body 6.
  • a screw 30 or similar means is provided which permits axial displacement and adjustment of the contact arm 10, in order to permit the position of the latter to be adjusted so that it will engage the body 6 behind and to one side of the general plane of the contact face of the tool, in order to assure that the removal of solid lubricant from the body 6 will take place in spiral tracks.
  • this removal which is governed by the relative speed of the body 6 and the tool 1, there will be a constant displacement of the body 6 under the influence of the pressure of spring 16, in the direction of the arrow 31 and towards and of course in contact with the material-removing surface of the tool 1.
  • FIG. 7 shows an arrangement capable of affording the same operations as in FIG. 6, but being structurally somewhat different.
  • the body 6 is again identified with the same reference numeral as before, but is of disk-shaped configuration, being required to advance in direction of the arrow 31 against the contact face of the non-illustrated .tool.
  • the arm 10 has been omitted.
  • a spindle 32 is provided on the shaft 7, having threads which mesh with the threads of a threaded body 33 which in turn is connected towards a pull rod 34 having a knob or handle 35.
  • the member 33 can be displaced against the pressure of the helical spring 36 in direction transversely to the longitudinal axis of the shaft 7. In so doing it becomes disengaged from the spindle 32, permitting a partial displacement of the shaft 7 in the direction of the double-headed arrow 38, depending upon which direction is required, with such displacement being effected manually.
