Definitions

  • This invention relates in general to a driving device for a cylindrical object, and more particularly to a driving device which is adapted to be used in a crankshaft induction hardening machine, such as that shown in United States Patent No. 2,787,566 to G. Seulen et al., to transmit the rotary motion of a rotating faceplate to the Workpiece to be hardened.
  • An object of the present invention is the provision of a driver that will accurately center the rotational axis of the workpiece with the rotational center of the faceplate.
  • Another object of the invention is the provision of a driver which will accurately position a crankshaft Within an induction hardening machine.
  • a further object of the present invention is the provision in a driver of the type hereinafter set forth of means for positively and accurately mounting the driver in driven relation upon the rotating faceplate.
  • a still further object of the present invention is the provision of a driver having a relatively simple design which is economical to manufacture, yet which is capable of rotating a cylindrical object in a trouble-free manner.
  • FIGURE l is a side elevational View drive construction
  • FIGURE 2 is la sectional view taken along line 2 2 of FIGURE 1
  • FIGURE 3 is a detail view of one device.
  • FIGURE l is used to indicate the faceplate of an induction hardening machine, which is rotated by means, not shown, as is well known in the art.
  • Faceplate 10 is provided with a tapered bore 11, which is coincidental with the rotational center of the faceplate.
  • Faceplate 10 is further provided with a slot 12 that extends radially outward from the bore.
  • the induction hardening machine is provided with means for supporting one end of crankshaft 13.
  • crankshaft 13 is provided with a reduced cylindrical portion 13' (as shown in FIGURE 2) :that is received in the driving device indicated generally at 14 which forms the subject matter of the present invention, and which is mounted upon faceplate 10 to transmit the rotary motion thereof to crankshaft 13.
  • Driver 14 includes a tubular sleeve member 15, the inner diameter 16 of which corresponds in size to the outer diameter of the end of the workpiece being hardened.
  • Sleeve is suitably counterbored as shown at 17, to provide a seating means for bushing 18, which serves to align the driver with the center of rotation of the faceplate 10, as will hereinafter become more fully apparent.
  • a centering pin 19, having a cylindrical end portion 20, the outer diameter of which corresponds in size to the inner diameter .of bushing 18, is mounted Within sleeve 15 by being fitted into bushing 1S.
  • the other end of centering pin 19 is tapered as shown at 21, the taper corresponding in size to the taper of opening 11,
  • Driver 14 is provided with a second tubular sleeve 22, the axis of which is disposed at substantially right angles to the axis of sleeve 15.
  • the lower part of sleeve 22 is provided with a cut-out portion 23 which is positioned upon a similar cut-out portion 24 formed in the upper portion of sleeve 15, so that the interior of the two tubular members communicate with each other.
  • Sleeve 22 is integrally secured to sleeve 15, such as by welding shown at 25.
  • Means for clamping crankshaft 13 are provided within tube 22, and in the illustrated embodiment comprise a pair of jaw members 26 and 27 which are positioned on opposite sides of the crankshaft 13. Jaws 26 and 27 are each provided with internally threaded bores, such as shown at 28 in FIGURE 2, the thread of jaw 26 being of opposite hand to the thread in jaw 27.
  • a clamping screw 29 is provided with spaced apart externally threaded portions 30 and 31 of opposite hand which cooperate with the internally threaded bores 28 of jaws 26 and 27 to move the jaws laterally Within sleeve 22 into clamping engagement with crankshaft 13.
  • clamping screw 29 extends outwardly from sleeve 22, and is adapted to cooperate with a tool to effect the translational movement of jaws 26 and 27 Within sleeve 22.
  • Pins 33 and 34 extend across the end portions of sleeve 22, and are engageable with jaws 26 and 27 respectively, to provide a stop means to limit the outward translational movement.
  • Driver 14 is provided with a third tubular sleeve 35 which is secured to the bottom of sleeve 15, and has its axis disposed in substantial parallelism with the axis of sleeve 15.
  • Plunger 36 is slidably mounted within sleeve 35, and is pro-vided with a tapered end portion 37 which is cooperable with slot 12 to provide the driving connection of driver 1d with faceplate 10.
  • Plunger 36 is bored at 38 to receive a spring 39 which biases the plunger into positive engagement With slot 12.
  • the interior of sleeve 35 is threaded at 40 to accommodate plug 4l, which is provided with a recess 42 that seats spring 39.
  • the tension in spring 39 may be adjusted by threading plug 41 to any desired position within sleeve 35.
  • the bottom rof plunger 36 is provided with a cut-out portion 42 which cooperates with pin 43 that extends across sleeve 35 to provide stop means to limit the movement of plunger 36 within sleeve 35.
  • a driving device adapted to rotate a cylindrical object comprising: a iirst tubular sleeve adapted to receive one end of said object, a second tubular sleeve mounted on said irst sleeve yand extending at substantially right angles thereto, said second sleeve being positioned on said first sleeve so as to communicate W'th the interior of said first sleeve, jaw members slidably mounted within said second sleeve and positioned on opposite sides of said first sleeve, means for moving said jaw members toward each other into clamping engagement with said end of said object, and means for mounting said iirst sleeve in driving relation with said faceplate.
  • 'mounting means includes a centering pin -positionedwith in said first sleeve and adapted to engage said faceplate at its center of rotation, and a driving pin associated with said rst sleeve and adapted t o drivingly engage said faceplate at a point spaced from thecenter of rotation of said faceplate.
