Rotary Table With Frameless Motor

US Patent:
2008004, Feb 28, 2008
Filed:
Aug 24, 2006
Appl. No.:
11/508853
Inventors:
Daniel P. Soroka - Horseheads NY, US
Richard Kesterke - Lawrenceville PA, US
Joseph T. Colvin - Horseheads NY, US
Lloyd Weidman - Pine City NY, US
Jeremy Turner - Horseheads NY, US
Assignee:
HARDINGE, INC. - Elmira NY
International Classification:
B23C 1/14
US Classification:
29 27 C, 409168
Abstract:
A rotary table for a material processing machine such as a vertical milling machine utilizes direct drive motor(s) to precisely angularly position a work piece along one or more pivotal axes. The direct drive motor(s) are thermally insulated from the remainder of the machine to limit misaligning thermal expansion of the components of the machine. The motors may be symmetrically attached to their respective supports such that thermal expansion/contraction of the motor and surrounding components occurs symmetrically with respect to the motor to limit misalignment of the motor's rotational axis. A motor may mount to its respective support only at a first axial end thereof such that thermal expansion of a second axial end of the motor does not adversely shift the position of the first end. Axially narrow clamps selectively secure the rotors of the motors in desired positions.

Workholding Clamping Assembly

US Patent:
2007006, Mar 22, 2007
Filed:
Sep 7, 2006
Appl. No.:
11/516727
Inventors:
Daniel Soroka - Horseheads NY, US
Richard Kesterke - Lawrenceville PA, US
Assignee:
Hardinge, Inc. - Elmira NY
International Classification:
B23Q 3/00
US Classification:
269309000
Abstract:
A failsafe workholding clamping assembly includes a base, an axially slidable draw bar and collet, and a force amplifier. A driver applies a continuous driving force to the force amplifier. The force amplifier amplifies the driving force and applies a resulting amplified force to the draw bar to bias the draw bar toward its closed position and the collet toward its gripping position. A collet opener mounts to the base and selectively applies an opening force to the draw bar to counteract the driving force and move the collet into its released position. The workholding clamping assembly holds a collet in a predetermined rotational orientation and includes a draw bar rotating mechanism to enable an operator to rotate the draw bar to threadingly engage the draw bar and a rotationally-fixed collet.
