Nahodil, Cuyahoga Falls, and Harold E. Correll, Greensburg, Ohio, assignors to The Goodyear Tire & Rubber Company, Akron, Ohio, a corporation of Ohio Filed Apr. 14, 1966, Ser. No. 542,489 US. Cl. 77-58 Int. Cl. B23b 47/22 9 Claims ABSTRACT OF THE DISCLOSURE This invention relates to a hydraulic-actuated recessing tool, and, more particularly, to a tool for cutting O-ring grooves, and the like, inside a cylinder.
It is the general object of the invention to provide a tool of the type described, and characterized by inexpensiveness of construction, ease and speed of operation, lack of maintenance, facility of cutting adjustment, and operation upon various cylinder sizes.
FIGURE 1 is a longitudinal cross section of a preferred embodiment of the apparatus of the invention;
FIGURE 2 is a bottom plan view of the apparatus of the invention illustrated in FIGURE 1 but with the cutting tool removed;
FIGURE 3 is a cross sectional view of the apparatus of the invention illustrated in FIGURE 1 as seen from line 33 of FIGURE 1; and
FIGURE 4 is a cross sectional view of the apparatus of the invention illustrated in FIGURE 1 as seen from line 44 of FIGURE 1.
In the drawings, with particular reference to FIGURE 1, the numeral 1 generally indicates the housing of a rotary mounted turret of the type present in a conventional boring mill, or turret drill. It should be understood, however, that the apparatus of the invention is not limited for use therewith, but is easily adapted for use on a conventional drill press or the like. The turret 1 rotatably carries a socket 2 which is adapted to be rotatably driven about its axis by suitable drive means indicated diagrammatically at 3. The rotating socket 2 is adaptel to receive therein a shank or body 4 which is removably stabbed in the socket 2 and secured thereto for rotation therewith by a plurality of set screws 5. The shank 4 has an integral, axially-directed, hollow cylinder 6 which slidably receives in fluid-tight relationship a piston or motor 7. Fluid port means 8 and port means 9 are positioned in the cylinder walls at opposite sides of the piston and connect to circumferential grooves 10 and 11 on the outer surface of the cylinder, respectively, so that external fluid pressure means (not shown) can effect a downward or upward movement of the piston 7 in the direction of the arrows 12 in FIGURE 1 when said fluid pressure means are actuated.
To supply the fluid pressure to the rotating cylinder 6, a stationary sleeve 13 is provided which rotatably surrounds the cylinder, as best illustrated by FIGURE 1.
atent O The sleeve 13 has radial ports 14 and 15 which connect to the circumferential grooves 10 and 11, and a plurality of O-rings 16 are carried by the sleeve 13, said O-rings sealing the cylinder within the stationary sleeve 13 at both sides of the grooves 10 and 11. One or more support rods 17 are secured to and extend from said stationary turret 2, with the downward extending end of the rod being received by a 'fork 18 secured to the sleeve 13. The fork 18 engages with the end of the rod 17 so that the fork 18 prevents the sleeve 13 from rotating with the cylinder 6, but wherein the fork 18 is not prevented from sliding downwardly off the end of the rod 11. This arrangement permits the entire shank 4, cylinder 6, and sleeve 13 to be dropped out of and away from the rotating socket 2 by simply loosening the set screws 5 which secure the shank 4 to the socket 2 as it is stabbed therein.
A cap 19 is threadably secured to the lower end of the cylinder 6 at 20 and is locked in place by suitable set screws 21, the cap having a circumferential flange 22 rotatably engaging with the bottom of the stationary sleeve 13 to prevent it from moving downwardly. The cap 19 also receives for sliding movement a piston rod 23 secured to the piston 7. The lower end of the piston rod 23 carries a clevis 32 which is secured thereto by means of a threaded pin 31.
A body 24 is secured to the cap 19 by a plurality of cap screws 25 in the manner best illustrated by FIG- URE 1. The body 24, of inverted channel-shape in cross section, has a base 30 and a pair of integral downwardly extending side plates 26 and 27. The side plates 26 and 27 each have a window 28 cut therein and also the base 30 has a substantially circular opening 29, as best illustrated by FIGURE 3. This opening 29 is adapted to receive the lower end of the piston rod 23 and the clevis 32 carried thereby.
Slidably received by the body 24, and being best illustrated by FIGURE 3 and 4, is a support or slide 34 which is pivotally connected to the clevis 32 so that as the piston rod 23 moves downwardly, the slide 34 moves in a direction perpendicular to the direction of stroke of said piston and to the axis of rotation of the shank 4. The connection of the slide 34 is achieved by linkage or link 35 which pivotally connects the slide 34 to the clevis 32. One end of the link 35 is received by the clevis and is pivotally connected thereto by a pin 33. The other end of the link 35 is pivotally connected to a pin 36 which extends between two integral ears 37 and 38 of the slide 34 in the manner best illustrated by FIGURES 3 and 4.
Ways or gibs 39 are secured to the lower edges of the side plates 26 and 27 of the body 24 by suitable cap screws 40, and said gibs 39 are adapted to slidably engage the bottom lateral edges of the slide 34 to guide it in its sliding movement. As seen in FIGURE 4, the top lateral edges of the slide engage the lower inside edges of the side plates 26 and 27. In order to prevent lateral movement of the clevis as the piston rod moves downwardly, a pair of thrust rollers 41 and 42, rotatably mounted on a dowel 43 supported by the side plates 26 and 27, engage with the side of the clevis. Thus, when the fluid pressure means actuate the piston 7 forcing it downwardly in the cylinder 6, the slide 34 moves in a direction perpendicular to the direction of stroke of the piston.
In order to limit the forward and backward sliding movement of the slide 34, a pair of end plates 44 and 45 are secured to the body by suitable cap screws 46 and a pair of stops 47 are adjustably mounted on the end plates. The stops 47 are threadably received by the end plates 44 and 45 and thus can be adjustably turned to limit the movement of the slide 34.
A tool block or cutting bit 48 is adjustably secured to the slide 34 by cap screws 50 as best illustrated by FIGURES l and 2. The tool block 48 has a plurality of slots 51 through which the cap screws 50 extend. This allows the tool block 48 to be selectively positioned on the slide. For controlled adjustment of the tool block 48 on the slide 34, adjusting screw means 52 extend between the block and an ear 53 on the slide. Thus, cap screws 50 can be loosened, the block 48 adjusted by the screw means 52, and the cap screws 50 retightened.
A tool 49 is carried in the tool block 48 being releasably secured thereto by a set screw 54. The described structure permits a very fine cutting adjustment of the tool 49, and operations upon work pieces of various internal diameters.
FIGURE 1 illustrates the apparatus of the invention positioned to cut an O-ring groove 55 (shown in dotted lines) on the inside wall of a cylinder 56, the lower portion of the cylinder being broken away.
It also should be understood that the mechanical interaction between the piston 7 .and the tool block 48 can still be achieved if the socket 2 is stationary, with rotation being imparted to the work piece.
While a certain representative embodiment and details have been shown for the purpose of illustrating the invention, it will be apparent to those skilled in this art that various changes and modifications may be made therein without departing from the spirit or scope of the invention.
