A rotary indexing table assembly includes an axis of rotation, a rotation element and a receiving assembly. The rotation element is rotatable about the axis of rotation and has a centering opening coaxial with the axis of rotation. The receiving assembly has a spring system and a pin assembly. The pin assembly has a pin body, movable along the axis of rotation by the spring system and settable in a set-up state or a blocking state. In the set-up state, the rotation element is releasably connected to the receiving assembly, and in the blocking state, the rotation element is fixedly connected to the receiving assembly.

A rotary table according to the exemplary embodiment of the present disclosure includes a piston 70 having a first tapered portion 72, and a clamp 80 having a second tapered portion 82. When the first tapered portion 72 comes into close contact with the second tapered portion 82 by a movement of the piston 70, a pallet base 30 is fixed to a table base 10, and thus the pallet base 30 is rotated, thereby maintaining a preset posture.

A circumferential positioning device of automobile hub having rotary positioning seat, transition seat, bearing, positioning pin, positioning cylinder, bearing, base frame, main rotating shaft with sliding spline, coupling assembly, link snap-gauge assembly, lead screw, connecting bolt, nut, servo motor, lower bracket of main rotating shaft, small bracket of belt servo motor, belt pulley servo motor, small belt pulley axle, small belt pulley, belt, large belt pulley. 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 order to provide a tool changer that can detect an entry of a foreign substance into a turret mechanism portion or wear of a turret mechanism part, a tool changer of the present invention includes a reference phase false detection sensing portion that monitors load variations which occur in a turret drive source and detects an entry of a foreign substance into the turret mechanism portion based on a difference between the load variations and a reference load used as a reference. Moreover, the reference phase false detection sensing portion can also detect the progress of wear of the turret mechanism part based on the integral of the absolute value of a difference between the load variations which occur in the turret drive source and the reference load used as a reference.

An inclining and rotating table apparatus includes a position adjusting mechanism for adjusting a position of an inclination frame with respect to a driven shaft at least in a vertical direction and provided between the driven shaft and the inclination frame, in which the driven shaft is formed in a hollow shape such that at least a part of a rotation drive motor is disposed therein, and has an attachment portion to which the inclination frame is attached and which extends in a radial direction and allows attachment of the rotation drive motor to the inclination frame, and the rotation drive motor is supported on the driven shaft via the inclination frame.

An angle head holder is installed on a spindle having a positioning block mounted on its outer surface with a constraining groove. The angle head holder includes a body base, a driving shaft, a holder assembly, and a positioning device. The driving shaft and the holder assembly are disposed in the body base. The positioning device has a fixing ring and an adjusting assembly. The fixing ring is sleeved on the body base and has a receiving slot. The adjusting assembly has a connecting block, a positioning pin, and at least one lever pin. The connecting block is mounted to the fixing ring and has a receiving groove. The positioning pin protrudes out of the receiving groove, is limited by the constraining groove, and has a retaining groove. The at least one lever pin is mounted in the receiving slot and the retaining groove.
