Document Type and Number:
Japanese Patent JP5057568
Kind Code:
B2
Abstract:
A clamping device for a rotary index device for a machine tool, in particular, a normal clamp type clamping device makes it possible to simplify the structure thereof and to maintain a stabilized positioning performance. In a rotary index device (1) for the machine tool, in which the index position of, for example, a circular table (16) is maintained by normally clamping a clamp disc (11) with clamping means (6) and in which, for example, the circular table (16) is unclamped by unclamping means (13) when an indexing operation is performed, the clamping means (6) includes a fixing portion (7), a resiliently deformable supporting portion (8), and urging means (10). The fixing portion (7) is fixed to a housing (3) of the rotary index device (1) for the machine tool. One end of the supporting portion (8) is secured to the fixing portion (7), and a pressing portion (9) having a face that opposes the clamp disc (11) is secured to the other end of the supporting member (8). The urging means (10) normally urges the supporting portion (8) towards the clamp disc (11) to realize a state in which the clamp disc (11) is pressed by the pressing portion (9).
