A tool machine magazine includes a base, a tool disc disposed on the base, tool sleeves disposed on a periphery of the tool disc through a bearing, a motor, a brake structure, a cam, a driver shaft, an angle sensor, and a control terminal. The motor drives the cam to operate. Each bearing orderly operates along the outline of the cam, driving the tool disc to continuously rotate without intermittence. The angle sensor is disposed on one end of the driver shaft or a rotation center of the tool disc. When the rotation angle of the tool disc matches the tool change command, the control terminal controls the brake structure to stop the motor, so as to stop the tool disc for facilitating the tool change operation.

The present invention provides a rotation indexing device where a shaft of a rotary joint is configured so that an outlet of a supply path opens to a lower surface of a flange part, a jig plate is formed to have a through-hole in which the flange part of the shaft is arranged and a flow path formed so that an inlet opens to a lower surface of the jig plate, and the jig plate is directly attached to a main shaft. Also, the rotation indexing device includes an adapter that is provided in contact with the flange part of the shaft and the jig plate and has a communication path for communicating the outlet of the supply path in the shaft and the inlet of the flow path in the jig plate each other.

Disclosed is a rotary indexing table (10) having an output flange (12) which is suitable for receiving a workpiece, mounted on a housing (14) of said rotary indexing table (10) for rotation about an axis of rotation (A) and drivingly connected to at least one drive element (24) which engages a driving groove (22) in a cylindrical cam (20) which can be driven by a motor, the cylindrical cam (20) being disposed asymmetrically to the axis of rotation (A) of the output flange (12).

A rotary table (10a) for a milling machine, comprising sensing means (30,32) configured to measure and/or calculate a clearance between two mating components of said rotary table (10a), and transmission means configured to transmit said measured/calculated clearance to a central processing unit. The mating components of the rotary table being a worm screw and a worm wheel.

A method and apparatus for changing pallets delivered to a machining center. Different workpieces are connected or attached to different pallets. A first workpiece corresponding to a first pallet is delivered to or near an indexer or indexer assembly and the indexer is moved into an engaged position and performs a work operation on the first workpiece. The indexer is then moved to a disengaged position and the first pallet and the first workpiece are exchanged or switched out with a second pallet having a second workpiece. The indexer is then moved to an engaged position and works the second workpiece and when completed, the indexer moves to the disengaged position and the second workpiece is exchanged or switched out with a third pallet having a third workpiece. The indexer system of this invention can quickly and cost-effectively cycle through different pallets and thus different workpieces.

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.

The cleaning device includes a base, an indexed table, a driving mechanism and a power transmission mechanism. The driving mechanism includes a driving device including a drive shaft and a first engaging member. The drive shaft rotates around a first axis. The first engaging member is disposed on the first axis to rotate integrally with the drive shaft. The power transmission mechanism includes a second engaging member, a propeller shaft, a piston, and a reduction gear.

A driving device including a drive shaft and a first engaging member. The drive shaft rotates around a first axis. The first engaging member is disposed on the first axis to rotate integrally with the drive shaft. The power transmission mechanism includes a second engaging member, a propeller shaft, a piston, and a reduction gear. The second engaging member is disposed on the first axis engageable with/disengageable from the first engaging member. The propeller shaft is rotatable integrally with the second engaging member around the first axis. The piston reciprocates the second engaging member between a first position and a second position along a direction of the first axis. The reduction gear is joined to the other end side of the propeller shaft to decelerate the rotation of the propeller shaft. The reduction gear causes an output shaft joined to an object to rotate around a second axis.
