According to the present invention there is provided a unit for driving a tool, comprising a tool carrier supported for rotational and translational movement, first means for transmitting rotational drive to the carrier along a main power path, and second means branchconnected with this main power path and arranged to impress translational movement on the carrier upon flow of rotational drive along the main power path.
For a better understanding of the invention and to show how the same may be carried into effect, reference will now be made, by way of example, to the accompanying drawing, in which the single FIGURE is a sectional side view of a tool driving unit.
The unit shown in the FIGURE is shown set-up for driving a tool that is a tap 1. This tap 1 is removably mounted in a tool carrier 2 that is supported for rotational movement, and for translational movement along its axis of rotation, in a housing 3 of the unit. Within the housing 3 a pinion 4 is fast with the tool carrier 2 centrally along the length thereof. Engaged with the pinion 4 is a drive pinion 5 that is engaged with a drive shaft 6 that enters the housing 3 from a prime mover (not shown). The teeth of the pinions 4 and 5 are straight teeth, in each case parallel with the rotational axis of their pinion, and these rotational axes of the two pinions are parallel, whereby translational movement of the pinion 4 and carrier 2, relative to the pinion 5, along the axis of rotation of the pinion 4 and carrier 2 can take place.
The end, located within the housing 3, of the carrier 2 remote from the end to which the tap 1 is attached has removably secured to it an externally threaded member 7 which is engaged in a correspondingly internally threaded member 8 removably secured in the housing 3 so as to be fast against rotation. Accordingly, upon rotation of the member 7 with the carrier 2 the inter-action of the members 7 and 8 is such as to cause translational movement of the carrier 2. Y
There are thus provided, in the unit, the shaft 6, pinion 5 and pinion 4 that serve to transmit rotational drive to the carrier 2 along a main power path, and the inter-engaged threaded members 7 and 8 that are branch-connected with this main power path and which impress translational movement on the carrier 2 upon flow of rotational drive along the main power path.
It is to be noted that the members 7 and 8 can be removed from the unit, without disturbing the components included in the main power path, and replaced by differently threaded members so that a desired length of translational movement can be obtained. Likewise the pinion 5 is mounted in the housing 3 so as to be replaceable, whereby a desired speed of rotation of the carrier 2 can be obtained.
The unit is suitable for driving tools other than taps, for example a rearner. The pinion 4 can be driven other than by a pinion engaged therewith. For examplethe pinion 4 can be engaged with a rack. A single pinion or rack can be engaged with pinions 4 of several drive units each being as just described.
Units such as described can be mounted in different types of machines, for example strip forming machines; transfer presses; progressive tooling/dies; and C.V.A./- Henry Wright type presses. With the present units production speeds up to and in excess of strokes per minute and tool life of taps in excess of fifty thousand passes can be obtained.
