Title:
工作機械用の割出し装置におけるクランプ装置
Document Type and Number:
Japanese Patent JP5216528
Kind Code:
B2
Abstract:
A clamping device (6) for holding an indexed angular position of a main shaft (2) includes a clamp section (20) non-rotatable relative to the main shaft, and a pressing mechanism (40) including a clamp piston (42) displaceable in an axial direction of the main shaft and causing a fluid pressure received by the clamp piston to act on the clamp section. The clamp section includes a first clamp portion (21) being non-rotatable relative to the main shaft, and a second clamp portion (31) being rotatable with the main shaft. The pressing mechanism includes first and second pressing portions (43, 44) which respectively press the first and second clamp portions. The second clamp portion or the second pressing portion is elastically displaced when the clamp piston advances by the fluid pressure. Forces in axial and radial directions are respectively applied to the first and second clamp portions, thereby clamping the main shaft.
