    摘要: A valve inserting apparatus for an internal combustion engine has a cylinder head of the engine supported by a jig such that its surface on a combustion chamber side is positioned facing upward and the longitudinal axis of a valve guide assembled to the cylinder head is kept vertical while a valve is inserted into the valve guide from above. The valve inserting apparatus includes a valve inserting unit for moving upwards and downwards. A valve holding device detachably, swingably, holds the valve with its head portion facing upward. A valve push-in device is provided and a suction device moves into contact with a lower end of the valve guide. The push-in device comprises an upwardly and downwardly movable push rod having a weight attached to the upper end portion. The push rod abuts the head portion of the valve from above. The valve inserting unit includes a first detector for detecting whether or not the push rod is at a position higher than a first predetermined reference position, such that the position of the push rod when the push rod in abutment with the valve and the valve inserting unit has been lowered to a predetermined position where the lower end of the valve has been inserted into an upper end of the valve guide to a predetermined depth. The valve inserting device further includes a second detector for detecting whether or not the push rod is at a position lower than a second predetermined reference position, that is, the position of the push rod when the lower end of the valve reaches the stem seal.

    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.
