Abstract: 1,265,364. Making valve sleeves; chucks; indexing; grinding; planing machines; spark erosion. A. E. BISHOP. 3 March, 1969 [20 March, 1968], No. 11280/69. Headings B3A, B3B, B3D, B3L and B3V. [Also in Divisions B7 and F2] A method of making a cylindrical valve sleeve comprises machining the external surface of a rough sleeve to an accurate reference surface, holding the sleeve by the reference surface, removing material from the sleeve bore intermediate the bore ends to form a dead-ended groove and finish machining the bore interior. A rough finished sleeve 117 is secured by collets 55 in a sleeve 54 of a support 50, the sleeve being symmetrically disposed about the axis of rotation of the support. The support is rotated in 90 degrees steps and a fixed cam 70 engages yoke rollers 63 to open or close the collets, which are normally held closed by springs 57. Cutting tools 39 are held in holders 72 and are pivotable about axes 74 of arbor shafts 75. Crank arms 80, which are linked to eccentrics 83 in a shaft 82, oscillate the shafts 75. As viewed in Fig. 5, the tool cutting stroke occurs during clockwise movement of the crank arms. The support 50 is held in the machining position by a motor actuated biasing rod 94, which causes abutments 90 to engage a stop support 91. A surface 110a on a cam 110 co-operates with a follower 111, which is connected to the support 91, to turn the stop support 91 anti-clockwise, thereby pivoting the support 50 clockwise. A shaft 120 raises the cam 110 to pivot the support 50 progressively and so increase the depth of cut. The upper end of the shaft 120 is provided with a follower (134) engaging a cam (133) mounted on a shaft (131), the rotational speed of which determines the rate at which the depth of cut is increased, Fig. 8 (not shown). A further cam (135) on the shaft (131) oscillates a shaft 136, Fig. 6, at the completion of a rotation of the shaft (131), to drive a shaft 138 downwardly to index the sleeves 117 via a ratchet mechanism and detent, Fig. 11 (not shown), and allow the next groove to be cut. When a machining cycle is completed, the support 91 is de-latched and the rod 94 retracted. Links 96 on the rod pivot a rack 102 into engagement with a gear 104 and a motor 101 is actuated to rotate the support 50 through 90 degrees. A conventional mechanical counter may be applied to the sleeve 52 or shaft (131) to count the number of slotting operations performed and control indexing of the work support. The grooves may alternatively be formed by grinding or spark erosion.
