A work handling apparatus includes a pair of traveling guides (') provided so as to extend in a front-and-rear direction X at right and left sides, and a pair of direct-acting arms (&#x2032;) provided so as to travel independently on the pair of traveling guides. The direct-acting arms are extendable from contracted positions, at which the arms oppose each other and avoid mutual interference in a right-and-left direction Y, to extended positions at which the arms overlap with each other. An operation spot () is arranged in an operation area () sandwiched between the pair of traveling guides for performing a predetermined operation to a work. Also, work tools (&#x2032;) are attached to the pair of direct-acting arms (&#x2032;), respectively, for transferring the work between a work storage area () and the operation spot () or performing an operation after transfer.

Work handling apparatus

A work conveying system for conveying works in a clean room includes a work holder for holding works, and a moving unit for moving the work holder.

Work conveying system

A machine part such as a shaft is inserted or pressure-fitted into a hole in a workpiece by setting the workpiece on a table which is rotatable around at least two axes, rotating the table so as to orient the hole vertically, holding the part vertically by an assembly tool, operating a two-dimensionally moving mechanism so as to move the assembly tool within a horizontal plane and to position the part vertically above the hole, and using an elevator to move the two-dimensionally moving mechanism vertically. Since both the part and the hole are vertically aligned, no torque is generated on the part during the insertion process.
