A rotating axis supporting device of the present invention includes: a housing; a rotating axis rotatably pivoted to the housing; a case for fixing the housing; and an adjustment mechanism adjusting a position of the rotating axis by causing an attachment surface of the housing attached to the case to be perpendicular to an axial direction of the rotating axis, attaching the housing to move relative to the case in parallel to the attachment surface, and moving the housing and the case relative to each other in parallel to the attachment surface.

A machine tool includes a tool magazine configured to hold a plurality of tools, the tool magazine having a rotary unit rotatable around a predetermined rotary axis and a measured portion provided in the rotary unit, a sensor disposed outside of the rotary unit in a radial direction that is perpendicular to the rotary axis, and configured to detect the measured portion, and a controller configured to detect a position of an origin point of the rotary unit based on a result of the detection by the sensor.

A tool support incorporates height adjustment and locking features in common components. A pivoting door is used to control the engagement of a height adjustment threaded shaft with the bearing flange of the power tool, with the position of the pivoting door controlled by a manual actuator. In one position the manual actuator allows the door to pivot outward to disengage the height adjustment shaft from the bearing flange. In a second position the manual actuator moves the door to engage the height adjustment shaft with the bearing flange to permit micro height adjustment by rotation of the height adjustment shaft. In a third position the manual actuator presses the door into the height adjustment shaft to effectively lock the shaft in position.

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 present disclosure discloses a table for an optical alignment device, an optical alignment device, and an optical alignment method for a substrate. The table for an optical alignment device includes: a base including a rotation shaft; a support component connected with the rotation shaft; an installation component connected with the rotation shaft; a plurality of sliding guiding mechanisms connected with the installation component; and a plurality of groups of light shielding mechanisms; wherein each sliding guiding mechanism is slidably installed with a group of light shielding mechanisms, each light shielding mechanism in each group of light shielding mechanisms includes a light shielding plate which can slide to above a selected area of the support component.

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.
