Definitions

  • ABSTRACT A unitized tapping head is incorporated into the turret of a multiple-tool punch press
  • the tapping head includes a unique replaceable cartridge which houses a tap and a feed lead screw.
  • a self-contained drive unit rotates the cartridge to advance the tap at the same lead as the threads on the feed lead screw.
  • the cartridge is held only by a simple spring clip and thus is easily replaced with the same or a different combination tap and corresponding feed lead screw.
  • FIG. 1 is a schematic perspective illustrating a typical numerically controlled punch press embodying a unitized tapping head.
  • FIG. 2 is a vertical section of the preferred tapping head embodiment.
  • FIG. 4 is a plan illustrating a portion of the unique cartridge used in the tapping head.
  • FIG. 5 is a fragmentary section of the tapping head illustrating the preferred cartridge of the invention.
  • FIG. 6 is a typical circuit diagram for automatically advancing and retracting the tap.
  • FIG. 3 is a section taken along the line 3-3 of FIG.
  • FIG. 7 is a section of a modified form of tapping head utilizing a hydraulic drive.
  • FIG. 8 is a section taken along the line 88 of FIG. 7.
  • a numerically controlled punch press 10 is shown illustrated with a multiple-tool rotary turret l2 and a work supporting table 14.
  • the work supporting table is provided with conventional workpiece positioning means 16 which are controlled by a numerical control (N.C.) device 18.
  • N.C. numerical control
  • the NC. device operates to position the workpiece and the rotary turret according to a prearranged program so that a desired operation takes place on the workpiece and then repositions either the rotary turret or the workpiece or both to perform the next desired operation.
  • a unitized tapping head 20 embodying the principles of the invention. Al though the tapping head is uniquely applicable for a multiple-tool turret type punch press, it is also advantageously employed in a conventional single stationary tool holder type punch press in which the tools are interchangeably' employed.
  • the unitized tapping head 20 includes a base 22 which is locked into the turret 12 by any suitable means.
  • the base houses a self contained conventional pneumatic or electrical motor 24 which may be operated in the forward or reverse directions and has a self-energizing brake which stops the output shaft of the motor prior to initiating motion in the opposite direction.
  • an electrical motor will be described; however the principles are equally applicable to a pneumatic motor.
  • the motor 24 is secured to the base by suitable means and is provided with an output shaft 26 that is coupled to worm gear 28.
  • the worm gear 28 meshes with a pinion 30 which may be rotated by the worm gear either in the clockwise or counterclockwise direction.
  • the pinion gear is mounted for rotation in the base in suitable bearings 32 and is provided with an internal axial bore 34.
  • the bore 34 is provided with axial grooves 36 for a purpose to be described.
  • the tapping head 20 is provided with a unique replaceable tapping cartridge 38.
  • the tapping cartridge includes a core member 40 having an upper axial bore 42, a lower axial bore 44, and a plurality of splines 46 which slidably engage within the grooves 36 of the pinion gear 30.
  • Removably secured in the bore 44 is a conventional tap 48 having a cutting thread of a prescribed lead.
  • the tap must be simultaneously rotated and advanced axially into the bore at a prescribed rate so that the proper lead is provided in the thread being cut in the bore.
  • the desired thread lead is obtained by a feed lead screw 50 having threads at the same lead as the cutting edges of the tap 48.
  • the lead screw is threaded into a bushing 52 that is rigidly secured to the core member 40.
  • the lead screw is fixed against rotation in the base by a cap screw 54 that is seated partially in a notch in the head of the lead screw and partially in a complemetary notch in a latch plate 56 that is secured to the base 22.
  • rotation of the core member 40 through rotation of the pinion 30 will cause the bushing and thus the core member to thread itself downwardly on the fixed lead screw 50, thus advancing the tap 48 at the desired lead into the workpieceW.
  • this tapping head It is a particularly advantageous feature of this tapping head that the cartridge 38 is easily removable from the tapping head to be exchanged with either an identical cartridge or one having a feed screw and tap of a different lead configuration.
  • the head of the lead screw 50 is provided with a circumferential groove 58 that is aligned with a groove 60 in the latch plate 56 when the cartridge is inserted in the tapping head.
  • a conventional spring clip 62 is shown in FIG. 4 as being expanded to fit partially within the groove 58 and partially within the groove 60 so that the cartridge is held locked within the latch plate 56.
  • the groove 58 is of a smaller internal diameter than the bore in the latch plate so that by pressing the ends of the spring clip together the circular portionof the clip is retracted entirely within the groove 58 and the cartridge can then be removed from the tapping head. Installation of a new cartridge is accomplished in the reverse manner by compressing the spring clip 62 inserting the cartridge and then allowing the spring clip to expand to again engage the groove 60. It is, of course, quite apparent that this substitution can be accomplished quickly and without any special tools.
  • this tapping head it automatically senses its position relative to the depth of the tap into the boreof the workpiece so that reversal of the drive motor and retraction of the feed screw may take place automatically and thus become a part of the program of the numerical control device.
  • the core member is provided with a cam slot 64 in which a spring biased switch arm 66 is engaged. Movement of the core member axially causes the switch arm 66 to ride out of the cam slot and engage a switch contact LS2.
  • a cam slot 68 is engaged by a switch arm 70 which engages a contact LS1 when the switch arm 70 is within the cam slot 68.
  • Contacts LS1 and LS2 are incorporated into the circuit shown in FIG. 6. As is best shown in FIGS.
  • the contact LS2 is opened with switch arm 66 seated in cam slot 64.
  • contact LS1 is also opened with the switch arm 70 riding out of the cam slot 68.
  • Closing of switch 72 either manually or from a signal from the NC. device 18 as part of a predetermined program energizes relay R1 through normally closed contact R2.
  • Relay contacts R1 are closed to lock-in the circuit through relay R1.
  • Closi-ng contacts R1 in the motor circuit will initiate forward operation of the motor so that the pinion 30 is rotated in the direction necessary to advance the tap 48.
  • the switch arm 70 enters the cam slot 68 thus closing contact LS1. Since LS2 remains open, however, no change occurs in the circuit.
  • the switch arm 66 When the core member has advanced to the desired distance such that the tap has threaded the hole in the workpiece, the switch arm 66 will ride out of the cam slot 64 closing contact LS2 thus completing 'the circuit to relay R2. Contacts R2 are closed to lock-in the relay R2 and to open the contacts to the relay R1 while simultaneously closing the contacts R2 to the reverse motor circuit. As is understood in motors of this type, the motor will first brake itself to a. stop and will then begin operation in the reverse direction threading the core member 40 upwardly out of the workpiece. When the core member reaches its uppermost position as shown in FIG. 2,
  • contact LS1 will again be opened thus opening the circuit to relay R2. All of the contacts in the motor circuit will then be opened and the motor will brake itself to a stop ready for the next signal to begin operation. If part of a prearranged program, opening LS1 will signal to the NC. device to sequence to the next operation in the program. Y
  • FIGS. 7 and 8 employs a cartridge 38 basically identical to that shown in the preferred embodiments.
  • Base 22a is modified slightly so that the cartridge 38 is directly coupled to the base member by a set screw 54a which seats in complementary notches in the head of the lead feed screw 50 and the base member 22a.
  • a pinion 80 also connected to the body member by a spline and groove connection as in the preferred embodiment, is drivingly engaged by a pair of hydraulically driven gears 82.
  • a single gear could suffice, but the double gear arrangement advantageously increases the torque to the pinion.
  • the gears 82 are journaled in the base member 20 and are simultaneously driven by fluid entering ports 84 for rotation of the pinion in one direction or fluid entering ports 86 and exiting ports 84 for rotation in the opposite direction. Operation of the modification is basically the same as that of the preferred embodiment.
  • the numerical control device will send a signal to the fluid source to direct fluid into either the ports 84 or 86 and upon receipt of the various signals from switches LS1 and LS2 the motor will be brought to a stop and then reversed.
