Provided is a robot cell apparatus in which a cooperatively operable area for a pair of robot arms can be widened and which has an excellent workability. The present invention includes a table with a plane having a quadrangular shape in plan view, a workpiece being placed on the plane. Proximal ends of robot arms are respectively fixed to two corners at diagonal positions among four corners of the plane of the table. A cooperatively operable area in which the pair of robot arms are cooperatively operable is formed in a space above the plane of the table.

Robot cell apparatus and production system

To enable positioning a robot arm and a workpiece with high accuracy while reducing vibrations of a camera. According to the claimed invention for this purpose, a robot stationincludes a pedestalto which robot armsandare fixed, a camerawhich images an area including a working areaof the pedestal, and a boothto which the camerais fixed. The pedestalis fixed to a floor surface, and the boothis fixed to the floor surface without contacting the pedestal. The boothis formed in the shape of a rectangular parallelepiped having a short side parallel to a workpiece conveying direction T and a long side perpendicular to the workpiece conveying direction T in a plan view. In the booth, the length of the long side y of the boothis set to not less than the sum of a maximum length by which the robot armsandprotrude from the pedestalin a direction perpendicular to the workpiece conveying direction T and the length in the direction perpendicular to the workpiece conveying direction T of the pedestalin a plan view.

Assembling apparatus and production system

A strain wave gear apparatus includes a rigid internal gear, a flexible external gear, and a wave generator. The wave generator includes an input shaft fixing member including eccentric cams, bearings respectively fixed to outer sides of the eccentric cams, and housings respectively fitted to outer peripheral surfaces of the bearings. The eccentric cams are arranged side by side in a direction of an inclined axis inclined with respect to an input rotation axis at an inclination angle (&#x3b8;) in a manner that respective center axes of the eccentric cams are parallel to the inclined axis and decentered in directions opposite to each other from the inclined axis. The housings are each formed into a tapered shape so that an outer peripheral surface of each of the housings is held in surface contact with an inner peripheral surface of the flexible external gear.

Strain wave gear apparatus

A method of processing a leading portion of a rotating workpiece is performed by rotating a tip mounted on a cutter shaft and facing an outer circumferential surface of the workpiece. The tip has a small radius of rotation for high precision processing with small cutting resistance. The leading portion is cut by the tip with the cutter shaft inclined to a side opposite to the leading portion of the workpiece with respect to a direction orthogonal to the axis of rotation of the workpiece.
