KONING TOOL FOR EXTERNAL CYLINDRICAL SUBFACES Filed NOV.l 19, 1946 lll 27 Z4 1,3/ INVENTOR. g3 ffl/41. TEA. fiPc/AK- IIIIIIIIIIIIIIIII Patented June 28, 1949 UNITED STATES PATENT OFFICE HONING TOOL FOR EXTERNAL CYLINDRI- CAL SURFACES 3 Claims.
y l This invention relates to an outside diameter honing machine, and has for one of its objects the production of a simple and efficient means for `reducing or removing irregularities upon cylindrical surfaces, and for bringing the cylindrical Work to a correct size and also to highly polish the surface.
A further object of this invention is the production of an eicient `honing mechanism which will yprovide a range of sizes within one shop, so that any outside honing job within a. given range such as .125 to 3.00 may be handled without the necesm sity of providing extra individual honers.
Other objects and advantages `of the present invention Will appear throughout the following specification and claims.`
In the drawing:
Figure 1 is a plan view of the outside diameter honing machine assembly, certain parts being shown in section;
Figure 2 is a side or edge View thereof, the supporting member being shown in transverse section;
Figure 3 is a sectional View taken on line 3-3 of Figure 1;
Figure 4 is a sectional view taken on line 4--4 i of Figure 1;
i, the insert sleeves looking at right-angles to that shown in Figure 5;
Figure '1 is a top plan view Vof the sleeve shown in Figure 5;
Figure 8 is a side elevational view of lone of the inserts;
Figure 9 is a side elevational view of one of the inserts looking at right-angles to that shown in Figure 8.
By referring to the drawing, it will be seen that I designates the body or holder for the honing members. The body Ill is `provided with three radiatingv legs Il, I2 and I3, and a central aperture I4. The legs Il, l2 and i3 carry caps l5, I6 and l1, respectively, at their Iouter ends, which caps are anchored in position upon the outer ends by means of anchoring screws such as are indicated at lll in Figure 1 with respect to leg Il. The heads of these screws are preferably countersunk, as at I9. Each cap is anchored in position in a similar manner. The cap I is apertured, as at 20, and the support or handle 2| extends therethrough, as shown in Figure 3.
The radial leg ll of the tool is provided, as is shown in Fig. 3, with a central socket 22 which extends from its outer extremity to open into the central aperture it of the tool body i. A sleevelike member 23 slidably inserted into the socket 22 and is retained from rotation therein by longitudinal keys 24 which engage key-Ways in the socket 22 in a conventional ner. The lower portion 0i" the Sleeve member 23 reduced in di ameter to form a central threaded aperture therein through which threaded extension of the handle El is passed to extend beyond the bottom of the sleeve. A tool insert provided with a threaded socket Ztl in one is slidably inserted into the lower end of the socket 22 so that the threaded socket receives the extended threaded end of the handle extension 25. The lower end of the sleeve member 23 is provided with a tapered socket 33, while the inserted end of the tool insert is `pro-Jided with a tapered tongue 32 which iits snugly into the sleeve socket 33 when the threaded extension 255 is rotated to draw the insert up llush. with the sleeve. The lower extremity of the tool insert is provided with an enlarged outer end thereby forming shoulders 29 which act as abutments to engage the periphery of the central aperture ll and limit the inward movement `of the insert The sides` of the insert 21, at that portion thereof adjacent the outer extremity of the insert, converge, as at 30, to denne a concave or straight honing, or lapping, face 3l. To complete this assembly a coil spring 34 is carriedabout the handle 2| and seats between the sleeve shoulder formed at its point of reduced diameter and the inner face of the cap l5. Thus by the means of the structure defined, the insert tool 21 is yieldably supported Within and without the tool leg l I The inserts or tools 35 and 31 may also be yieldably mounted in a similar manner, if desired, but it is preferable in many instances to support the inserts or tools .it and 31 in a set adjusted position and merely support the insert or tool 2.1 in a yieldable manner. The inserts or tools 3B and 31 are preferably held in a set adjusted position by means Aof the structure shown in Figures 1 and 4 wherein the inserts or tools 36 and 31 which are formed similarly to the insert 21 are engaged by a suitable screw Sil, the head of which screw 38 is seated in the socket 39 oi the insert sleeve 4l). rI'he screw 38 extends through the sleeve 40 and into the insert 31 as shown in Figure l. The sleeve 39 is held against rotation in the leg I2 by means of a suitable key-way lll. A set-screw l2` passes through the leg I2 and binds against the sleeve 40 at the key-way il to lock the sleeve 40 in a set adjusted position,
The insert or tool 31 is also adjusted to a selected position by means of the adjusting screw 38. The insert or tool 36 is similarly supported in a manner shown in section in Figure 1, which illustrates the mounting in detail for the insert 31. In view of the fact that the structure which supports the insert 36 is merely a duplicate of the structure which supports the insert 31', it is thought; unnecessary to duplicate this description.
It should be understood that the device herein described is intended to be held rmly by the user, and the work (rod, spindle,l etc.) is. rotated. by the lathe, drill, milling machine, or similar mechanism. The present device, therefore, dif fers from the conventional grinding or honing machines wherein the grinding or honing devices are usually rotated and the work is held stationary.
It should be further understood that certain y detail changes: may be made in the present device without departing from the spirit of the invention, so lon-g as these changes fall-within the scope of the appended claims. 21 and sleeves 23', are removable s-o that they may be replaced by elements of varying sizes, the elements themselves being adjustable and thereby providing. means. for honing cylindrical surfaces of considerable variance within a given range.
I. A device of the character described comprising, a body provided with a work receiving aperture and' a plurality of hollow outwardly radiating legs.v said legs having open -outer ends, -1
each o1v said legs provided with a socket extending throughout its1 length, a` sleeve member held against independent rotation within each of said sockets, each sleeve. having a tapering socket at one end, a honing.' tool having an inner tapering end tted into engagement with the socket of each ofy said sleeves to properly align the tool, said tools converging on the ycentral axis` of the work receiving aperture', an elongated anchoring screw rotatably' adjustable longitudinally of each of' said sleeves', said screws carrying said tools, one ci sai'd tools being. held' in engagement with the Work under the resilient tension of a coil spring to yieldably contact the work within the work receiving aperture, the remaining tools being selectively adjustable toward and away from the work,.and a removable closure for the open. outer end of each leg for shielding said Having described the invention, what I claim s `4 anchoring screws within said legs against contact with foreign objects and thereby avoiding maladjustment of the tools.
2. A device of the class described comprising a body having a work receiving aperture, said body having a tool receiving socket, a sleeve adjustable longitudinally within said socket and locked against rotation therein, said sleeve having a tapered socket at its inner end, ahoning tool having a tapered tongue at. its inner end tting snugly within the tapered socket of said sleeve to properly center said tool relative to said sleeve and socket, and a screw extending longitudinally of. the sleeve and passing through said tapered socket and into the tapered end lof said tool for locking the tool in tight fitting engagement in said socket.
3. A device of ther class described comprising a body having a Work receiving aperture, said body having a tool receiving socket, a sleeve adjustable longitudinally within said socket and lockedv against rotation therein, said sleeve having a tapered' socket at its inner end, a honing tool having a tapered tongue at its inner end iitting snugly within the taperedV socket of said sleeve to properly center said tool relative to said sleeve and socket, a screwv extending longitudinally of the sleeve and passing through said tapered socket and into the tapered end of said tooll for locking the tool in tight tting engagement in said socket, said tool having laterally extending shoulders extending parallel to the central axis of the work receiving aperture and extending ush with the grinding face of the tool to provide a wide honing area on the tool and to act as abutments and toi limit the inward movement of the tool relative to the periphery of the Work receiving aperture.
