Valve inserting apparatus for an internal combustion engine

摘要

A valve inserting apparatus is provided for an internal combustion engine having an intake valve and an exhaust valve inserted into respective valve guides on the intake and the exhaust of engine. The valve inserting apparatus comprises a pair of valve supply devices for supplying intake valves and the exhaust valves. A jig has a jig plate, a jig base and a horizontal shaft. The jig plate is supported on the jig base and is swingable about the shaft. A valve inserting device inserts both the intake and exhaust valves. A base for the two valve supply devices and the jig is disposed circumferentially around the base. A supporting column is mounted on the base. The supporting column is movable to advance towards and retract from the jig. The valve inserting device is supported on a swingable frame swingably mounted an the supporting column. By advancing and retracting the supporting column and swinging the swingable frame, the valve inserting device is moved between a position above each of the valve supply devices and a position above the jig. The valve inserting device inserts an intake valve into the valve guide on the intake side when the jig plate is swung to the first swung position, and the valve inserting device inserts an exhaust valve supplied from the exhaust valve supply device into the valve guide on the exhaust side when the jig plate is swung to the second swung position.
