    摘要: A centering spindle for use with a workpiece which is to be induction hardened includes a generally cylindrical outer housing into which a shaft is positioned and mounted in spaced relation to the housing by a bearing arrangement. The bearing arrangement allows the shaft to rotate relative to the housing. The end of the shaft extending out of the housing is connected to an isolation spacer which is fabricated out of an electrical insulator material. The isolation spacer in turn is attached to a removable tip which is constructed and arranged for interfacing with the workpiece to be induction hardened. The design of the centering spindle is such that the tip may be removed and replaced when it becomes worn without the need to replace any of the other parts or components of the centering spindle. Further, any electromagnetic field induced in the workpiece and transmitted to the tip will not be transmitted to the shaft nor to the bearing arrangement due to the isolation spacer. Additionally, any substantially elevated temperature which is experienced by the tip due to the heating of the workpiece will be insulated to some extent from reaching the shaft due to the thermal insulation properties of the material used for the isolation spacer.

    摘要翻译: 与被感应淬火的工件一起使用的定心心轴包括大致圆柱形的外壳,轴通过轴承装置与轴承座间隔开地安置在轴中。 轴承装置允许轴相对于壳体旋转。 延伸出壳体的轴的端部连接到由电绝缘体材料制成的隔离间隔件。 隔离垫片依次连接到可移除的尖端,其可构造和布置成与工件接合以进行感应淬火。 定心心轴的设计是这样的:当刀头磨损时可以移除和更换刀片,而不需要更换定心心轴的其他部件。 此外,由于隔离间隔件,在工件中感应并传递到尖端的任何电磁场将不会传递到轴或轴承装置。 此外,由于工件的加热而由尖端经历的任何基本上升高的温度将由于用于隔离间隔物的材料的绝热性能而在一定程度上被绝缘到达轴。

    摘要: A center for lathes comprises a tubular casing with its interior serving as an oil chamber, a center rod fitting in the casing and having a conical front end projecting from the casing, front bearings and a rear bearing provided between the casing and the center rod, an oil feeding screw portion positioned between the front bearings and the rear bearing and formed on the center rod, and an oil reservoir provided on the casing. Forward and return oil channels extend between the oil reservoir and the oil chamber to permit the whole oil in the reservoir and the chamber to circulate within the center.

    摘要: 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.

    摘要: Adjustable live or dead center apparatus adapted for use in rotatably supporting a workpiece to be turned during lathe operations and further adapted for accurate correction of lathe center and/or piece part misalignment which is likely to occur with respect to a mounted workpiece having its surfaces eccentric relative to the centers thereof. The center apparatus employs a center arrangement or assembly including a nose portion which is mounted for limited movement transversely of the longitudinal axis of a lathe spindle. A plurality of selectively operable adjustment means are utilized which, when operated, are effective to alter the position of the nose portion of the center arrangement with respect to the longitudinal axis of said spindle.
