Definitions

  • the workpiece to which the ring is to be assembled and which usually comprises a grooved shaft of pin with its fixture is manually fed from above the applicator after the operator has first positioned said workpiece axially so that the shaft or pin groove is vertically aligned with the then most advancedring held in' the cut-out by the jaws of the applicator blade.
  • a principal object or" the present invention is to eliminate the aforesaid requirement by providing a combination ring dispensingjand applying tool of the stated type incorporating workpiece positioning and feed means effective both to position the workpiece so that its groove in which a ring is to be'assembled is accurately aligned with the applicator blade and hence with the most advanced ring in assembly readiness position held thereby, and also to positively feed said workpiece to. the applicator blade as required to effect the assembly operation.
  • a more particular object of the invention is the provision of a combination ring dispensing and applying tool incorporating workpiece positioning and feed means as aforesaid, characterized in that said means includes a simple hand-operated plunger mounted for vertical rec'iprocation and which is provided with a transverse workpiece receiving opening disposed to insure mounting of the workpiece in horizontal position above the vertical applicator blade, in conjunction with abutment means serving to permit insertion of the workpiece into said opening only the exact amount as to accurately align the workpiece" groove into which a ring is to be assembled with the most'a'dvanced ring of the tool then along-the length of the shaft or pin thereof.
  • Fig. 3 is a broken-away detail View illustrating the workpiece positioned for a ring dispensing and assembly operation: I
  • Fig. 5 is a separated view of the parts making up the feed plunger guide means as herein proposed.
  • the aforesaid applicator blade 16 corresponds to the applicator blade disclosed in my prior application Serial No. 508,264, filed May 13, 1955 that is to say, it comprises two springy side arms 17, 17a which terminate in plane jaw members 18, 18a whose adjacent edges are curved so that they together form a substantially circular ring-receiving cut-out 20 contoured to conform to the outer-edge contour of the rings being assembled.
  • said plane jaw members have thickness equalling that of the rings being assembled,-and hence the axial depth of the cut-out 20 corresponds to that of the axial thickness of said rings.
  • the free end of the aforesaid rail 13 terminates just short of said jaw members 18,18a
  • the rings are positively biased to move into the applicator blade cut-out 20 when free to do so.
  • the latter mounts a slide 26 which is normally biased upwardly to a cut-out closing position shown in Fig. 1 by means of a spring 27.
  • the slide is free to partake of retracting movement with respect to the applicator blade upon its forward ([OPZZIOSL) being abutted by a workpiece being pressed against same in the ring-assembly operation.
  • a tool as aforesaid functions both to dispense single retaining rings from a stack thereof disposed in generally horizontal relation and to assemble each said ring in the groove of a workpiece shaft or pin responsively to the workpiece being positioned horizontally above the applicator blade 20 and so that its groove is in vertical alignment with the ring cut-out 24 of the applicator, followed by lowering of the workpiece so that the grooved portion of the shaft or pin moves into said cut-out, thereby to pick off and seat the most advanced ring of the stack thereof then in the assembly readiness position.
  • adjustable abu ment means for limiting the axial insertion of the workpiece to exactly that required for such alignment.
  • such comprises an abutment finger 37 secured to an upper-edge projection Ilia on the tool frame 11 in a position and at a level such that it extends forwardly-axially towards the plunger opening 33.
  • movement of the plunger 31) as aforesaid is entirely independent of that of the slide 26, of course excepting movement of the slide resulting from the latter being engaged by a workpiece inserted in the plunger opening 33. That is to say, wtihout a workpiece cooperated therewith as aforesaid, the plunger 35) may be freely depressed without corresponding retracting movement of the slide 26, as is a feature of advantage when it is desired to demonstrate the operation of the tool, for example, without at the same time pushing the stack of rings completely through the ring cut-out, as could happen if the slide were retracted without the workpiece or some other element being available to serve as an end stop for the stack.
  • said guide means 312 effectively dis poses the plunger 30 so that it reciprocates in a plane disposed forwardly of said applicator blade 16, and said plunger is moreover offset a slight distance forwardly of the slide 26.
  • said guide means 31 and the offsetting of the plunger 36 together serve to mechanically isolate the plunger from any direct engagement with the slide.
  • said guide means includes a relatively thick spacer member or bar 40 (Fig. 5) which is affixed to the front-edge frame flange 14, to the front face of which is secured a T-shaped key member 41 whose configuration is such as to provide two vertical slideways 42, 42a.
  • the lower offset end of the plunger is provided with a slot 33b into which the vertical leg of the key member fits, with the side bars or legs of the plunger as results from the provision of said slot operating in the aforesaid slideways 42, 42a.
  • This construction of course provides both for vertical disposition of the plunger and for its reciprocatory travel independently of the slide 26, when such latter is desired.
  • Means for dispensing open retaining rings singly from a supply thereof and for applying the single rings to grooved shafts, pins and the like including, in combination, a vertically disposed applicator blade terminating at its upper end in a pair of resilient jaws defining a semi-circular ring-receiving cut-out for a single ring which opens upwardly, retractible means slidably mounted on said applicator blade and normally closing one side of the cut-out, means disposed on the other side of the cut-out for maintaining a supply of the retaining rings being assembled in substantially horizontal alignment with one another and with said cut-out, spring means positively biasing said rings towards said cut-out and effective to cause said rings to feed one-by-one to the cut-out upon said cut-out being conditioned to receive same means for positively feeding a grooved shaft and the like into said cut-out so as to effect transfer of a ring contained in the cut-out to the groove of said shaft including, a vertically disposed plunger mounted for vertical reciprocating movement in a
  • Means for dispensing and applying open retaining rings substantially as set forth in claim 1, wherein said plunger provision includes a horizontally disposed through opening in which said shaft and the like is insertible, said opening having its axis parallel to that of the cut-out and being at a level as normally to position said shaft above said applicator blade as aforesaid.
  • said plunger provision includes a through opening for re ceiving said shaft, pin or the like, and whose axis is parallel to that of the cut-out, and which is disposed at a level as normally to position said shaft above the applicator blade as aforesaid, and wherein said shaft-end locating means comprises a stop finger operative to limit the depth of insertion of the shaft in said plunger opening to that required to vertically align the groove of said shaft with the applicator blade cut-out.
  • Means for dispensing and applying open retaining rings substantially as set forth in claim 5, wherein said stop means is adjustable horizontally thereby to accommodate said means to the assembly of rings on shafts whose grooves are differently located along the length thereof.
  • Means for dispensing and applying open retaining rings substantially as set forth in claim 5, wherein said applicator blade mounts a retractible slide serving normally to provide a side-face closure for said cut-out and being retracted by engagement therewith of the shaft feeding to said applicator.
