Claims

[Claims for Utility Model Registration] 1. An exchangeable head for a machine tool that is indexably attachable to and detachable from the spindle ram of a machine tool, and is provided with a fluid passage connected to a fluid passage provided in the spindle ram, A housing that rotatably supports a spindle and forms a fluid passage therein, a cylindrical part provided at the top of the housing, a joint member rotatably fitted to the outer periphery of the cylindrical part, and a joint member. A flange portion formed on the upper surface, and a joint member provided upright on the flange portion to engage with a fluid passage of the main shaft ram, the joint member having a plurality of fluid passages provided in the joint member and a plurality of fluid passages provided in the cylindrical portion of the housing. 1. An exchange head for a machine tool, wherein a fluid passage communicates with a joint member through a plurality of annular grooves formed opposite to each other in a cylindrical portion of a housing. 2. The exchange head for a machine tool according to claim 1, further comprising a ring member integral with the housing rotatably fitted to the outer periphery of the joint member, and comprising a ring member integral with the housing, which is a part of a plurality of fluid passages provided in the joint member. 1. An exchange head for a machine tool, wherein the plurality of fluid passages provided in the ring member and the joint member communicate with each other via a plurality of annular grooves formed opposite to the joint member and the ring member. 3. In the exchange head for a machine tool according to claim 1 or 2, the joint member erected at the flange portion of the joint member is connected to a joint engagement member provided on the main shaft ram in conjunction with clamping of the exchange head to the main shaft ram. An exchangeable head for a machine tool, characterized in that it is automatically inserted into the machine tool.
