But, the axle portion Va of engine valve V is tilted relative to the axis of three-jaw hollow chuck 70, be positioned at outside the radial direction of three-jaw hollow chuck 70 to make the umbrella portion Vb of engine valve V, from this state, make the umbrella portion Vb of engine valve V move closer to along the radial direction of three-jaw hollow chuck 70 towards center, thus, the umbrella portion Vb of engine valve V can pass through in the mode pushed through in the space between the claw 71 of three-jaw hollow chuck 70 and claw 71.
Before cam roller 46 engages with the front altitude datum part 161e of cam path 161 and supporting mass 42 arrives advance extreme position, supporting mass 42 keeps flat-hand position during sliding part 41 advances.The engine valve V that the handle part 421 of supporting mass 42 holds also keeps flat-hand position.Further, when supporting mass 42 arrives advance extreme position, the predetermined length of the umbrella portion that the comprises Vb of the engine valve V that handle part 421 holds is devoted in the hollow bulb 72 of three-jaw hollow chuck 70.Thus, engine valve V is fixed (with reference to Figure 10) by three-jaw hollow chuck 70 with predetermined length at handle side end Vc from the state that three-jaw hollow chuck 70 is given prominence to laterally.
Next, the shape of the cam path 181 of plane cam 18 is described.Meanwhile, about workpiece carrying device 50, the action of the undertaking position from engine valve V (advance extreme position) to launching position of sending arm 52 is described.
The cam path 181 of plane cam 18 is from the position sending the cam roller 56 when arm 52 is in advance extreme position of workpiece carrying device 50, in the scope of the position of the cam roller 56 sent when arm 52 mediates, in fact flatly extend.Using the altitude datum of its height as cam path 181.The altitude datum of cam path 181 has predetermined length to the left from the right part of cam path 181 in fig. 2.Using the altitude datum part 181a of this part as cam path 181.
The cam path 181 of plane cam 18 from workpiece carrying device 50 send arm 52 be in the cam roller 56 when retreating extreme position position, in the scope of the position of the cam roller 56 sent when arm 52 mediates, in fact flatly extend.The altitude datum of this aspect ratio cam path 181 is high.Using the height of this height as cam path 181.The height of cam path 181 has predetermined length to the right from the left part of cam path 181 in fig. 2.Using the height part 181c of this part as cam path 181.
Altitude datum part 181a and the height part 181c of cam path 181 pass through to be connected from the altitude datum part 181a sloping portion that height component 181c rises gradually upward.Using this part as sloping portion 181b.
When cam roller 56 cam path 181 altitude datum engaging time, workpiece carrying device 50 send arm 52 keep abutting part 521 to erect and with the center of three-jaw hollow chuck 70 just right just to posture (erecting posture).In the undertaking position (advance extreme position) sending arm 52 and accept engine valve V, cam roller 56 engages with the altitude datum part 181a of cam path 181 (with reference to Fig. 2).
When sending engine valve V, import cooling medium relative to the hollow bulb 72 of three-jaw hollow chuck 70 from rear side, utilize the flowing of this cooling medium (fluid pressure) to apply to discharge such pressure from three-jaw hollow chuck 70 towards front side (claw side) to engine valve V.Engine valve V is subject to this fluid pressure and side is moved forward because of umbrella portion Vb.Thus, the handle side end Vc of engine valve V abuts with the abutting part 521 sending arm 52 being positioned at advance extreme position.
Under the state that the handle side end Vc of engine valve V abuts with abutting part 521, sliding part 51 starts to retreat.Before cam roller 56 arrives the altitude datum part 181a of cam path 181 and the tie point of sloping portion 181b from advance extreme position, send arm 52 maintenance abutting part 521 during sliding part 51 retreats erect and with the center of three-jaw hollow chuck 70 just right just to posture (erecting posture).In the meantime, the state that engine valve V keeps handle side end Vc to abut with the abutting part 521 sending arm 52, and move (with reference to Fig. 3) side forward from three-jaw hollow chuck.
