Claims

[Claims for Utility Model Registration] (1) A bearing housing that also serves as a pressure oil supply pipe is provided inside the rotating table around the table main axis, and the pressure oil supply is provided around the bearing housing. A hydraulic cylinder operated by pressure oil supplied from a pipe, a first coupling member fixed to the lower end of the hydraulic cylinder, and a first coupling member fixed to the lower end of the rotary table below the first coupling member. and a third coupling member fixed to the upper end of the support frame of the rotating table inside the second coupling member. A rotary table indexing device for a machine tool, characterized in that it is equipped with the following. (2) Below the workpiece support surface of the rotary table, there is a bearing housing that also serves as a pressure oil supply pipe provided around the table main axis, and a bearing housing that is arranged around this bearing housing and is provided with a pressure oil supply pipe that is supplied from the pressure oil pipe. a hydraulic cylinder operated by oil; a first coupling member fixed to the lower end of the hydraulic cylinder; and a second coupling member fixed to the lower end of the rotary table below the first coupling member. , a cylindrical worm wheel rotatably supported by a support frame of the rotary table via a cross roller bearing;
A swivel table comprising a third coupling member provided at the upper end of the cylindrical worm wheel to face the first coupling member, and a worm gear for transmitting power from a servo drive motor to the cylindrical worm wheel. A rotary table indexing device for a machine tool, characterized in that it is equipped with a drive indexing and clamp/unclamp mechanism.
