Title: Improvements in or relating to Turret Operating Apparatus for Automatic Machine Tools.
Inventor: PULMAN WILLIAM ELLIAS REGINALD
IPC: B23Q16/02
Filed: 1967-06-06
Abstract: 1,174,445. Turrets. BROWN & SHARPE Ltd. 22 April, 1968 [6 June, 1967], No. 25996/67. Heading B3T.  An automatic machine tool such as a lathe, comprises an indexable tool turret 13 mounted on a reciprocatable slide 15, the movement of the slide being effected by a cam 23 which actuates a pivoted lever 22 on the machine frame and has a toothed sector 19 engaging a rack assembiy 18, 18a, 18b on the tool slide, the reciprocating movement of the slide being synchronized with the indexing of the turret by way of gears and clutch members 10, 11. A shaft member 25 rotatably mounted in the slide is driven through gears 31, 32 to operate the Geneva mechanism 24, 29 for indexing the turret and has a crank portion 26, 27 at one end which is connected by a rod 28 to a member 18b which portion 18a constitutes the rack assembly. During the operation of the machine tool the rotation of the shaft 25 produces a cyclic movement of the rack assembly 18, 18a, 18b relative to the slide 15 which provides additional clearance between the tools in the turret and the workpiece during the indexing operation. A spring 39 in a bore 41 in the machine frame acts on an abutment 42 therein and is connected to the slide by a plunger 43 pivotally secured to a lever 45 which is itself pivotally connected to an extension 46 of the rack assembly. The spring biases the slide away from the workpiece through the rack assembly and also acts on the slide through the roller 48 and lever 45 so as to take up any lostmotion in the mechanism whilst permitting relative movement between the rack and slide. Owing to the leverage ratio provided by the lever 45 the change in length of the spring during the reciprocation of the turret slide is barely affected by the relative movement between the rack assembly and the slide.
