Turret having rotating and non-rotating tooling
First Claim
1. A compound turret for machine tooling, comprising:
- (a) a first turret having non-rotating tooling;
(b) a second turret having rotating tooling;
(c) a housing operably associated with said first and second turrets;
(d) a base having an x-axis;
(e) means for rotatably mounting said housing on said base;
(f) said first and second turrets each having turret storage and turret operating positions;
(g) first, second and third indexing means;
(h) said first indexing means including means for rotating said first and second turrets about said x-axis between said turret storage positions and said turret operating positions;
(i) said second indexing means operably associated with said first turret for rotating said first turret about an axis transverse to said x-axis for selecting tooling positioned on said first turret for specific work operations;
(j) said third indexing means operably associated with said second turret for rotating said second turret about an axis transverse to said x-axis for selecting tooling mounted on said second turret for specific work operations;
(k) a first drive means for driving said first indexing means, said second indexing means and said rotating tooling; and
(l) a second drive means for driving said third indexing means.

Abstract
A compound turret for machine tools such as latches or the like having rotating and non-rotating tooling turrets mounted on a single housing. The compound turret includes a primary drive and a secondary drive. The primary drive includes a compound turret indexing unit operable to index the rotating and non-rotating tooling turrets into the turret operating and turret storage positions. The compound turret indexing unit consists of a harmonic drive that enables the operator to incrementally vary the turret operating position. The harmonic drive achieves high reduction ratios in a single stage thus eliminating the cumbersome gear systems usually implemented to achieve the reduction ratios required. The primary drive further includes a non-rotating tool indexing unit. The non-rotating tool indexing unit is operable to index the non-rotating tooling. The non-rotating tool indexing unit consists of a harmonic drive unit similar to the compound turret indexing unit. The primary drive further includes a drive connection for driving the rotating tooling mounted on the rotating tooling turret. The secondary drive includes a rotating tool indexing unit. The rotating tool indexing unit includes a motor divingly connected to a worm gear in constant meshing engagement with a worm wheel. The worm wheel is operably connected to the rotating tooling plate for indexing the tooling mounted thereon. In addition to indexing the rotating tooling, the worm gear and worm wheel drive connection enable the operator to perform offcenter machining. This is accomplished by simultaneously rotating the rotating tooling turret, via the worm gear and worm wheel, and the main spindle upon which the work piece is mounted.
