Claims

[Scope of utility model registration request]

Assemble parts such as a plurality of first rocker arms corresponding to one of the exhaust valve and intake valve, a plurality of cam holders, and a coil spring that surrounds the rocker arm shaft and is interposed between each first rocker arm to the rocker arm shaft. In addition, in a rocker arm shaft assembly device for assembling a second rocker arm, in which a shaft corresponding to the other of the exhaust valve and the intake valve and having both ends fitted to the cam holder is inserted between each cam holder, each cam holder is a plurality of base plates that are arranged in parallel at intervals and capable of moving toward and away from each other in order to position and place the base plates; and a spring interposed between each base plate to maintain the distance between the base plates; A plurality of movable plates are arranged between each base plate to enable movement in a direction parallel to the movement direction of each base plate, and parts such as the first rocker arm and coil spring are positioned and placed by enabling lifting and lowering operations. A plurality of first mounting jigs are arranged between the respective base plates, spacing adjustment rods are attached to the first mounting jigs so as to contact the base plates adjacent to each other on both sides, and a second rocker arm, etc. a plurality of second mounting jigs that are attached to the movable plate so as to be movable up and down in order to position and place components;
A support plate is provided on the movable plate to maintain the posture of each second rocker arm supported by the rocker arm shaft when the mounting jig is lowered, and a support plate is integrated with each base plate to clamp the cam holder between each base plate. a first clamper that is movable and has a posture holding plate for maintaining the posture of a first rocker arm supported by a rocker seam shaft when the first mounting jig is lowered; and a second mounting jig. The first rocker arm, coil spring, etc. can be clamped between the first mounting jig and the second clamper, which can clamp the second rocker arm, etc., and can follow the movement of the second rocker arm with its clamping force. a third clamper; and a positioning unit including a width shifting drive means capable of driving a base plate and each of the mounting jigs to reduce the mutual distance between the cam holders into which the rocker arm shaft is inserted; a rocker arm; an insertion drive unit that includes a holder that removably holds one end of the shaft; and a drive unit that is connected to the holder to insert the rocker arm shaft into parts such as a first rocker arm and a coil spring that are positioned in the positioning part; A rock arm shaft assembly device characterized by comprising;
