Abstract

1277076 Multi-spindle lathes PNEUMO DYNAMICS CORP 21 Oct 1969 [24 Feb 1969] 51490/69 Heading B3T In a multi-spindle machine tool such as a lathe having a main drive shaft 10 for a plurality of rotatable spindles 12, 13 and 14 mounted in an indexable spindle carrier 4 a plurality of fluid actuated clutches 85, 86, 87 and 24, 25 mounted on the spindles and counter shafts 15, 16 and 17 respectively are engageable selectively for independently driving the spindles from the main drive shaft at any one of a plurality, e.g. three different speeds. The spindles are driven through gearing and the clutches are selectively automatically actuated, the ratio of the gearing being determined by the spindle speed required. The indexing of the spindle carrier is effected by a Geneva type mechanism 93, 94 and 95 operated by an actuator 90 and through gearing to effect the required angular movement of the carrier which is determined by the number of work stations in a predetermined machining cycle. The spindle drum is looked in each of its indexed positions by a locking pin 115 which engages in a recess 117 provided at each required indexed position of the drum, the pin being actuated by hydraulic means 120. The drive to the drive shaft 10 is effected by belt and pulley 48, 49, 50 and gearing from a main motor 44 mounted on the machine frame housing 5. A plurality of fluid actuated cross slides 6 and 8 and end slides 7 and 9 are provided which relate to the number of work stations and the operations to be performed on workpieces carried in chucks carried in the spindles 12, 13 and 14. The operational sequence of the machine is described with reference to Figs. 21 and 22 (not shown). It is stated that operation of a pair of clutches in opposition may be effected to effect braking of a spindle.
