Definitions

  • This disclosure relates to a combined chordal gage and axial locator for use on grinding machines wherein cylindrical and annular surfaces are to be ground.
  • a combined, single mounting for the normally independent chordal gage and axial locator and a common means for advancing and retracting both devices are provided.
  • the gage and locating devices are advanced at the beginning ofa grinding operation and prior to work rotation to provide endwise or axial location of the workpiece in relation to the grinding wheel and, at this time, the locating device is made operative, whereas, the chordal gage is maintained inoperative and is maintained a small distance from the workpiece during the axial movement thereof.
  • the combined assembly is retracted, the grinding wheel is advanced, the workpiece is rotated, and the combined assembly is again advanced during the grinding operation whereupon the chordal gage is brought into operative engagement with the workpiece, whereas the axial locator is maintained inoperative.
  • chordal gage and locating device mounting the chordal gage and locating device on a single supporting member and for advancing and retracting the chordal gage and locating device as a single assembly prior to rotation of the workpiece.
  • the axial locator is brought into operative relation with the workpiece and is maintained operative until precise endwise or axial location of the workpiece is effected.
  • chordal gage is maintained inoperable and out of engagement with the workpiece while axial location is being effected and, conversely, upon rotation of the workpiece during the grinding operation, the chordal gage is advanced to ride on a peripheral surface of the workpiece to determine when size is obtained, whereas, the locating device or axial locator is maintained inoperative.
  • chordal gage is retained from the peripheral surface of the cylindrical workpiece during axial location through the provision of a pneumatically operated holdback cylinder, the chordal gage being preferably removed from the workpiece an amount slightly greater than half the amount of stock to be removed by the grinding operation to provide a specific inoperative position of the calipher during axial locating. Unnecessary friction on the workpiece engaging surfaces of the chordal gage is thereby achieved while the workpiece is being axially shifted into location.
  • the gage and its associated controller or control provisions are inoperable during axial positioning and are rendered operable when the grinding wheel is advanced for the beginning of a grinding operation.
  • Another object of this invention is to provide independent control of a chordal gage and axial locator, preventing the gage from being operable when the workpiece is axially posi tioned and preventing the locator from operating during the grinding operation.
  • a further object of this invention is to provide the signalling of full advancement or retraction of an axial locator by the provision of two airjets, the airflow of which is affected by full advancement of the locator into operative relation with a workpiece or retraction of the locator therefrom.
  • Yet another object of this invention is to provide an axial locator including a locator finger for carrying an air jet stylus and moving the stylus into and out of operative association with a workpiece to signal movement of the workpiece axially into proper relation with a grinding wheel.
  • Still a further object of this invention is to provide a locator finger according to the immediately foregoing object to control repetitively longitudinal positioning of the workpiece and including means for providing two-way adjustments of the stylus relative to the workpiece surface with which the stylus is brought into proximity.
  • FIG. I is a front elevational view of the grinding machine to which the invention is applied and shows an axially movable headstock and an axially movable tailstock controllable for axial location ofa workpiece for the grinding thereof.

  • the projection 50 is brought into alignment with the air jet 47, 'sufficiently blocking passage of air therefrom to effect signalling of full advancement of the arm 35.
  • the projection 51 is brought into alignment with the further air jet 48 sufficiently blocking that jet to effect signalling of full retraction of the locator arm.
  • Pivotal movement of the locator arm 35 is effected by a drive fork 52 supported upon a movable mounting bracket 53.
  • the drive fork 52 includes a downwardly opening slot 54 into which extends a drive pin 55 securely affixed to the pivotally mounted locator arm 35. Movement of the drive fork 52; then, toward and away from the workpiece W, effects pivoting of the arm 35.

  • a connecting bracket 80 joins the piston rod 77 and connecting bar 71, whereby actuation of the piston-cylinder arrangement 78 in opposite directions effects advancement and retraction of the entire combined gage and locator assembly 25.
  • chordal gage 31 With the combined gage and locator assembly in its advanced position, the chordal gage 31 is retained out of engagement with the workpiece W by the provision of a pneumatically operated holdback cylinder 81 which is supported upon a cylinder support member 82 for movement with the combined gage and locator device 25.
  • a piston rod 83 of the holdback cylinder 81 terminates in a linking member 84 which is connected with the chordal gage 31.
  • the chordal gage 31 In its advanced position, the chordal gage 31, by reason of its resilient mounting, is free for limited movement toward and away from the workpiece W and the holdback cylinder 81 is controlled to prevent movement of the chordal gage 31 into engagement with the workpiece W during axial location of the workpiece, thus limiting frictional engagement of the workpiece with the carbide inserts 32 and 33. Release of the chordal gage 31 by the holdback cylinder 81 allows the gage 31 to move into engagement with the workpiece W under the natural bias of the vertically extending leaf springs 67 and 68

This prevents energization of relay 7CR and the advance of the locator and gage assembly 25 at the end of a grinding operation after wheelhead 79 and gage 31 have been retracted and quill 16 is reset and before tailstock 13 is retracted to remove the finished workpiece, and contact 6CR1 is still closed.
