    摘要： A tool rest for a machine tool, with a plurality of rotary tools and a tool-rotating drive shaft supported rotatably so that its rotation is transmitted to each rotary tool. The tool rest includes: a plurality of input portions fixed to the tool-rotating drive shaft; and engaging portions corresponding to the respective input portions, rotatably supported and adopted to be driven in rotation by the input portions for engaging with engaged portions of each rotary tool to transmit power when a prescribed rotational phase is reached. Adjusting means is provided between a prescribed input portion and the engaging portion, for adjusting the phase of the engaging portion relative to the tool-rotating drive shaft such that the engaging portions and the corresponding engaged portions are engaged simultaneously.

    摘要： The present invention provides an indexing device for a turntable which is provided with a plurality of roller followers arranged at equal angular intervals; a cam component is provided on one side of the turntable. The cam component is provided with a first side rib wall with a continuous cam curved surface in a first direction and a second side rib wall with a continuous cam curved surface in a second direction, and the first side rib wall and the second side rib wall face opposite sides to form a cam groove with a variable groove width for guiding the movements of the roller followers and rotating the turntable; wherein the first side rib wall and the second side rib wall can compress on at least one pair of the roller followers of the turntable symmetrically in the first and second directions, so as to effectively eliminate the backlash problem between the cam component and the roller followers and improve the positioning accuracy of the turntable.

    摘要： The feed axis device of a machine tool is equipped with first and second planetary gear speed reducers, each of which is obtained from an inner element, outer element, and intermediate elements that are disposed between the two, the elements being disposed so as to be mutually rotatable and combined in series so that one of the three elements is a fixed section, one of the two remaining elements is the input section and the other is the output section. The element that is the input section of the first speed reducer and the element that is the input section of the second speed reducer are connected to a single drive source. The element that is the output section of the first speed reducer and the element that is the output section of the second speed reducer are connected. The feed axis device is provided with an actuator.
