Title: Face clamp chuck
Inventor: OKI MASARU
IPC: B23B31/19
Filed: 1996-03-07
Abstract: PROBLEM TO BE SOLVED: To perform chucking by making the chucking position at the front side of a work as the standard. SOLUTION: A work W is chucked by three presser elements 30 at the same intervals on the periphery of the front surface of a chuck main body 11, and a top jaw 18. The top jaw 18 is rotated by a draw bar through a rotary shaft 14, an actuator 13, and a shaft 12, and then draws back straightly, and its drawing-back is regulated by the end face (e) at the accurate position. Consequently, the chucking position (c) is positioned constantly and made as the standard. The presser elements 30 are energized by springs 32, and the work W is abutted to the presser elements 30 against the spring force, and after the top jaw 18 is rotated, they are abutted to the front side of the work W by drawing back to the set positions.  Under such a condition, the work W is centered by a chuck 24 having the periphery grasping function, and then a hydraulic pressure is led in to a piston 31, and the work W is chucked strongly by the presser elements 30 and the top jaw 18. Since the chucking position (c) of the top jaw 18 is constant in this case, the work W is chucked by making the position (c) as the standard, and machined in such a condition.
