The device in the present invention two radial grooves passing through the center that are formed in the bottom surface of the flange of the hub, correspond to the spoke direction on the facade of the hub and are just matched with the two radial bosses passing through the center on the top face of the positioning seat to achieve a positioning purpose.

In some examples, a moveable member including multiple tools is moveable relative to a fixed member to position a selected tool for performing an operation. A first connector half may be included on the fixed member for connecting to one of a plurality of second connector halves included on the moveable member. Movement of the moveable member to position the selected tool for performing the operation moves a respective second connector half associated with the selected tool into connection with the first connector half. In addition, a respective nozzle assembly may be associated with each tool. The respective nozzle assembly may receive multiple fluids including at least one fluid received through the connection between the connector halves. The nozzle assembly includes an inner nozzle that outputs a gas and an annular outer nozzle that outputs a machining liquid to generate a mixture to direct toward a tool-workpiece interface.

A tool carrier assembly for use at a machine tool, which includes at least one workpiece-carrying spindle for rotatably driving a workpiece received in the workpiece-carrying spindle. The tool carrier assembly includes a first slide being movable in a first direction, a tool carrier being supported on the first slide and configured to hold a plurality of tools, a tool drive unit including a tool drive for engaging with one of the plurality of tools held by the tool carrier to rotatably drive said tool, when the tool is arranged at a tool drive position with respect to the tool drive, and a drive mechanism for driving movement of the first slide together with the tool carrier in the first direction relative to the tool drive position, when the tool drive is disengaged with the tool, to relatively move another tool of the plurality of tools into the tool drive position.

A turret spindle locking fixture has a base, a flange extending radially inward from the base, and at least one locking structure extending from the flange or the base and adapted to engage a turret spindle. The turret spindle locking fixture is hands-free in that once the fixture is placed on a turret spindle, a user does not need to continue holding the fixture to lock the spindle.

The present invention discloses an MDOF (multi-degree-of-freedom) micro-lubrication intelligent spray head system for a CNC milling machine, comprising an annular rotating platform, a longitudinal telescopic part, a rotating part, an intelligent spray head mounting platform and an information acquisition system. The annular rotating platform comprises a rotating piece which rotates along a horizontal circumferential direction; a bottom of the rotating piece is connected with at least one longitudinal telescopic part; a lower end of the longitudinal telescopic part is connected with the rotating part; the rotating part rotates within a set angle range by taking a point connected with the longitudinal telescopic part as an axis; the intelligent spray head mounting platform is connected with the rotating part and moves along with the rotating part; and the information acquisition system is mounted on the intelligent spray head mounting platform.

A linear dividing indexer has an upper table which moves transversely linear relative to a base. The upper table defines a slot disposed at an angle with the transverse direction of movement and includes an indexing mechanism formed from (a) an angle bar pivotally mounted to the base and an actuator bar slidably mounted in the angle bar, the actuating bar having a cam follower which slides within the upper table slot; and (b) wherein when the angle bar is at an angle to the slot, linear movement of the actuating bar within the angle bar causes transverse linear movement of upper table relative to the base.
