Application filed July 31,
This invention relates to grinding machine fixtures and is particularly adapted to carry railroad equipment such as links, rods, and the like during the finishing operation of their hearing walls.
In grinding the bearing walls of railroad equipment of the class described and other irregularly shaped articles, considerable difficulty is experienced in readily securing such work upona grinding machine so that the wall to be ground will be in accurate alignment with the path of rotation of the grinding wheel.
An object of my invention is to provide a grinding machine fixture upon which work of the character described can be readily secured and positioned so that the bore to be ground will be-in accurate relation with the path of the'rotation of the grinding wheel.
A further object of m invention is to provide a fixture upon which work can be readily fixed with a definite knowledge of the relation of the bore to be finished to the axis of the rotation of a grindingwheel.
Another object of my invention resides in the provision of a dust collector which is associated with a fixture so that it can be adjusted to center with the bore of an article in any position of attachment in which it is operatively related with a grinding wheel.
These and other objects will appear more fully in the following specification in which I describe one embodiment of my invention.
In the accompanying drawings, Figure l is a plan view of a fixture embodying my invention mounted-upon the bed of a grinding machine; Fig. 2 is a front elevation of the same; Fig. 3 is a side elevation of the fixture; Fig. 4 is a vertical sectional view of the fixture taken on the line H of Fig. 2; Fig. 5 is a sectional view through the base portion of the fixture taken on line 55 of Fig. 1, illustrating the mechanism for moving a portion of the fixture transversely; Fig. 6 is a sectional view taken on the line 6-6 of Fig. 2 illustrating the mechanism for adjusting the mounting plate vertically; Fig. 7 is a perspective view of the fixture mounted upon a grinding machine bed with a railroad side rod secured thereto with its bore in position, to be ground; and Fig. 8 is a flectiimal View taken online 8 8 of Fig;
1925. Serial No. 47,225.
3 showing the side bracket attached to the mounting plate.
Referring now to the drawings by characters of reference, 10 represents the reciprocable bed of a grinding machine which supports the fixture assembly and moves it to and from the grinding wheel 11 which is securcdto the end of a shaft or spindle 12 mounted in the head of the machine. It will be understood that the grinding wheel s rotated in an orbital path and also about its own axis in the customary manner for grinding the interior wall forming the bear ing portion of articles of the nature set forth.
The machine bed is provided with longitudinally extending undercut slots 13 .in which the heads of bolts. 14 are slidably associated. The bolts extend through slot-' ted arms 15 which extend from the base member 16 of the fixture seated upon the machine and nuts1'7 are screwed upon the bolts to clamp the fixture base in desired longitudinal position upon the machine.
The upper face of the fixture base member is provided with a dovetail recess 18 which extends thereacross transversely relative to the axis of the grinding wheel shaft 12. A. frame is supported by the base 16 and comprises a base plate 19'from which a pair of ribs 20 extend vertically. The base plate formed with a dovetail. 21 which depends therefromand is complementary to and is seated inthe dove-tail recess 18 of the base member. The. fixture frame is slidable transversely upon the base member and is secured in desired adjusted relation therewith by the gib 22. A screw shaft 23 extends lengthwise of the dovetail 21 of the base plate of the frame and is screwed through a bearing 24.- which is secured to the base member 16 by studs 25. Suitable bearings 26 and 27 carried by the supporting.
frame, are provided for each end of the screw shaft and one'end of the screw shaft projects from the end of the base plate and is formed to receive a hand crank 28. By rotating the screw shaft 23, the fixture frame can be ad justed across the plate 16' in a direction trans versely across the end of the grinding wheel, it being understood that the gib is released during the adjusting operation. j I
a The front faces of theframe ribs 20' lie in the inus transverse plane, and pita-ids fill till

bearings for the end portions of the vertically extending mounting plate 29 of the fixture. Screw shafts 30 extend from the top of the mounting plate adjacent each rib of the frame and are secured to the plate by pins 31. A bracket 39,.is secured to the top ofeaeh rib by studsf'lti and such. brackets are formed as a housing at one end to receive the shafts 30. A cap 3t is secured over each of the housing portions of the brackets 32 by studs and a. vertically internally tl'ircaded rotatable bearing 36 is carried by eachof the housings so formed. The shafts 30 are screwed through the rotatable bearings, and agear37 keyed to each of the rotatable. bearings within the housings. Gears are. keyed to a shaft 39 which extends across the housings. and'mesh with the gears 37 within the housings. The shaft 39 projects from oneof the housings and is formed to receive a hand crank 40 bv means of which it canbe rotated. The rotation of the shaft 39rotates the gears 38 which are keyed theretoand theyv in turn rotate the gears 37- which will rotate the bearings 36 in unison. The rotation of the hearings will cause. the. shafts 30- to move vertically and will support the mounting plate in desired vertical position. Thefmounting plate will inthis. manner. he supported and adjusted in parallelismbv themeehanism just described, thus maintaining it, in uniformrelation with respect to the grinding wheel.
It will beseen that the mounting plate 29 can he. adjustedtransversely with the fixture frame. thatcthe 'fintureframe can be adjusted longitudinally upon the machine bed with the fixture base 16,- and that the mountin; platecan be moved vertically relative to the. fixture frame. Such adjustments will permit the operator to move readily the work carried; by the fixture. sothat it will align in the desired. relationwith theiaxis of. the
The adjustability of-theposition of. the mounting plate and the mechanismutilized for arranging and securing work upon the plate, makes LefiXt-ureespecially: desirable for supporting railroad andzother equipment. of an irregular shape, such as side rods. radius links, link hangers, eccentrierodsandithe like for a grindingoperation.
The uppenedgeportion 41 ofzthe mounting plate, extending intermediate. the ti);-
ture. frame ribsQO, is beveled to serv'eas av support fora palr of beams 2 against which.
the. work is. clamped: to the fixture. The. beams are. provided with gibs 43 having heir ,under surfaces. beveled complementary to the upper. edge of :the .mounting plate so v thatthevcan behookedover the, same and thus support the beams. The f beams are freely slidahle so that theyQcan be readily moved uponthe mounting plate to receive work having a bore of'varying diameter.
The work is clamped against the front faces of the beams 1-2 and the work will thus be spaced from the mounting plate so that a clearance wEll be proved for the grinding wheel during the finishing operation.
Ear-h end of the mounting plate is provided with a vertically extending slot 44 in which the head of a bolt to is slidably mounted. The bolt projects through the slot and (liltlltlH through an aperture in a work supporting bracket 46. and a nut ii is screwed against a washer 7: which is positioned on the bolt to secure tlnln'acl-art against. the end of the mounting plate. The bracket is provided with. ribs it) on each side, one of which tits in the slot 44 on one side of the plate to maintain the bracket in a fixed relation. 'llheprovisiou of the two ribs permits the brackettobe used on either side of the mounting plate. The bracket projects transversely from the face of the mounting plate and is provided with a horizontalli extending face which serves as a support for one end of a piee of work. and as the bracket can be adjusted iua vertical plane the work can besupported in the desired vertical position. The bracket can be adjusted when thenut. 47, is loosened.
The mounting plate 529 is n'ovidedwith a plurality of apertures 49 through which bolts 48 can be inserted to.position clamp members for securing work against. the beams 4:2. 'lhe apertures are arranged in horizontal and vertical parallel lines so as to accommodatethe. bolts indefinite relation for the varying sizes and shapes; which the work mayhave. The rear face ofzthe mount.- ing plate is formed; with projections 50 whichare horizontally arranged inparallel relation adjacent the apertures. and. be tween which the bolt heads can be inserted to secure them in. a stationary position. This construction saves time in securing the clamping bolts, thus assisting in the quick assembly. and: removal of; the. work from the.v mounting plate. The bolts extend through slots intbe clampingmcmhers 51, and one endof such clamping members is placed against thework 552, which is illustratcdias a side rod.- The. other end of the clamps til extend-from the.work and bear against. spacer blocks 53 which. are placed intermediate the clamps andthe plate 29. .l. washer to is positioned upon each bolt so thatit-exteuds across the slot in the. clamp anda nut 55 is screwed upon each bolt end and againstthe washers u'ntilthe work is securely. held between. them-lamps and the beams 42.
The front face of the. mounting plate mar be marked with vertical and horizontal graduations so that the workcan be accuratelj'. positioned upon the plate in a definiterclation with the axis ofthe movement of the. grinding W The ends of the llo transversely extending slot 56 which servesas a support for an adjustable dust collector which can be positioned with respect to the bore in a piece of workheld by the plate so as to collect all of the dust during the grinding operation. A bearing member 57 extends through the slot and is slidably mounted therein, and a conduit member 58 extends through and is carried by the bearing member. The conduit member is provided with outwardly extending pins 59 which engage in bayonet slots 60 formed in the bearing member to removably secure the conduit with the bearing. The end of conduit member 58 projects beyond the front face of the mounting board'and an annular collector head 61 may be secured thereto. A hose 62 is secured to the other end of the conduit member and a suitable suction device is associated with the hose. The bearing member is slidably mounted in the slot in the mounting plate and the suction device can thus be bodily adjusted transversely of the plate so that the head 61 will center with the bearing of the work to be finished in the various positions in which it may be secured with the late. One end of the bearing member is anged and the other end 63 is threaded, and a. nut 64 is screwed upon the threaded end to clamp the bearing against the mounting plate in desired adjusted position.
It will thus be seen that with such an arrangement the dust collector can be adjusted and secured in substantial alignment with the bore of the work being ground so that the dust or grindings may be more readily removed.
It will also be obvious that, if desired, the head 61 of the dust collector may be emptied and the work positioned substantially in alignment with the member 58.
It will be obvious that thework to be ground can be readily and accurately secured to the fixture and that the latter can be quickly adjusted to accurately positionprocedure can be made without departing from my invention as defined in the appended claims. 7
