Live Center With Hydraulic Pressure Indicator
|
Henry F. Swenson |
Roseland, Essex County, NJ |
Abstract:
This invention discloses a heavy-duty live center for a heavy workpiece usually of 10 or more tons. This center includes an outer quill or housing which is movable in a tailstock housing of a lathe or grinder. This live center incorporates the self-aligning front bearing arrangement shown in U.S. Patent application Ser. No. 643,909, filed Dec. 23, 1975. As described in that application this heavy-duty center has the center spindle bowed by the load and as the thrust increases because of heat, etc. there is a Belleville-type spring arrangement which accommodates the increased thrust. The outer housing or quill in the present invention receives the thrust of the load. The quill is moved into a workpiece supporting condition by the action of a screw on an enclosed nut in the rear of the quill. The thrust is measured by a hydraulic load cell and connected hydraulic pressure gage. This gage is carried on the forward exterior part of the housing. The hydraulic pressure is derived from the thrust on a closed circular hydraulic ring portion that measures the total thrust on the center. Belleville-type springs in combination with the hydraulic pressure cell accommodate the increase in thrust which occurs because of heating the workpiece during processing. |

Replaceable flinger for live centers
|
Henry F. Swenson |
Roseland, Essex County, NJ |
Abstract:
This invention pertains to a replaceable flinger for use with live centers. This flinger is placed as an auxiliary member on the hardened center. In addition to having a forward flinger adapted to withstand the abrasive action of chips, abrasive particles and the like, there is also a land portion on its rear on which the engaging lip of a grease or oil seal rides. When the center is to be reconditioned due to damage to the forward portion of the flinger or because of excessive wear to the seal engaging surface of the flinger, only the grease seal and the flinger need be replaced. This reconditioning does not require the replacement of the hardened center member. |

Gear Holding Hydraulically Actuated Chuck
|
Henry F. Swenson |
Roseland, Essex County, NJ |
Abstract:
This application discloses a work-holding chuck particularly for gears with their exterior teeth finished or substantially finished as by grinding, shaving and the like. This chuck has a plurality of hardened and finished pins which are moved and secured in a precise circular array and arranged as pairs on a ring member. A stop is provided so that the gear and the hub portion thereof is precisely located and positioned. Sliding segments are moved along a ramp guide by pneumatic or hydraulic means to bring the formed pins into the formed flanks of the teeth profile to repeatedly and precisely hold the gear by its formed and finished teeth. The held gear is now finished in its bore. Means are provided for readily changing the pins and position of these pins on the chuck so that gears of different pitch, number of teeth and/or lead may be accommodated.

Pivoted Jaw Members
|
Henry F. Swenson |
Roseland, Essex County, NJ |
Abstract:
This invention pertains to an auxiliary jaw which is adapted to be affixed to a movable member and as this movable member is advanced to and from a work-piece to grip and hold this workpiece when and while the auxiliary jaw is advanced. This auxiliary jaw includes a pivoted jaw member carried by a support member which is preferably secured to the movable member by cap screws. The pivoted jaw member engages the surface portion of the work-piece in local areas as it exerts a gripping force urges the workpiece toward the support surface. Three configurations of jaw assemblies are shown. Each has a pivoted jaw with one configuration supporting the work-piece above the pivoted jaw. In a second configuration the support as a pin means is below the pivoted jaw and in yet a third configuration the pivoted jaws are movable toward and to a support disk for multiple work-pieces. Soft jaws, hardened jaws and bias means may be used to bring the pivoted jaw to the desired condition. A cap screw retains the pivoted jaw to the support member and the pivot is at and on the upper extent of the support. This auxiliary jaw may be attached to any work table but is usually used with a chuck body on a lathe. The movable member is conventionally a T-member slidable in a T-slot in the chuck body. This auxiliary jaw may be used with independent jaws or self-centering jaws moved by a scroll plate. |
