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.

Turret having rotating and non-rotating tooling

An indexable machine tool turret comprising a body having a chamber, an opened end, a closed end and a central longitudinal axis; an axially displaceable rotatable turret top plate having a number of angularly spaced apertures for holding tools, said top plate being co-axial with said body axis; an axially displaceable and extending rotatable shaft connected to said top plate, said shaft co-axial with said top plate; two opposed annular face gears for seating said top plate to said body, said gears co-axial with and concentric with said top plate, one of said gears mounted in said top plate for engaging said other gear, said other gear mounted in said body; said shaft including a ring gear mounted concentrically thereto; means for displacing said shaft and thereby said top plate for causing said face gears to engage and disengage; drive means for engaging said ring gear for rotating said shaft when said face gears are disengaged; cushioned stopping means for stopping said shaft rotation; and, angular rotation detection means for determining said shaft rotation as a means for stopping said drive means and activating said stopping means when one of said apertures has reached a predetermined position is disclosed.

Indexable machine tool turret and attachments therefor

A two slide multiple axis machine comprising a machine tool bed having at least two parallel, spaced apart, longitudinal ways; a spindle mount fixedly attached to the bed; a rotateable spindle mounted in the spindle mount at a distance from the bed and having an axis of rotation parallel to the axis of the ways and adapted for receiving and detachably holding a work piece; first tool means engageable with said work piece and displaceably mounted for forward and rearward motion in the first of said ways parallel to the longitudinal axis of said ways; second tool means engageable with said work piece and displaceably mounted for forward and rearward motion in the second of said ways; first way cover means covering the first of said ways and fixedly attached to said first tool means and adapted for movement with said first tool means; and, second way cover means fixedly attached to said second tool means and adapted for movement with said second tool means is disclosed.

Multiple axis slant bed machine

A bed for a machine tool comprising a bottom, sides, a front, a rear and top with the bottom having a three point suspension and the top having a substantial portion inclined at between 55.degree. and 65.degree. from the horizontal and including a pair of spaced cavities within the bed which are ribbed and provide dual torque tube reinforcement.

Slant bed for chucker machine

Combined chucker and bar machine

A multi jaw rotary chuck for lathes and the like comprising a body having front and rear portions and including a bore, a plurality of spaced jaw guides in the front portion of the body, a plurality of movable master jaw supports for the jaws of the chuck, the jaw guides each having one of the master supports slideably guided thereby, a plurality of actuator plates in the body each mounted in spaced radial planes intersecting and parallel to the axis of the bore and each actuator plate having first, second and third apexes, the first apex of the plate having a hole and including a first dowel pin mounted in the hole and extending outwardly on either side thereof transverse to the plane of the respective plate, the second apex of each plate having a hole and including a second dowel pin mounted in the hole and extending outwardly on either side thereof transverse to the plane of its respective plate and generally parallel to the first dowel pin, pivot means on each of the actuator plates journalled in the body and positioned between its respective first and second dowel pins, a movable arcuate counterweight for each of the actuators operably connected to the first dowel pin and supported on the rear portion of the body, the second dowel pins each operably connected to one of the master jaw supports, a movable draw plug extending into the central bore and including actuator plate engaging means, the third apex of each of the actuator plates operably connected to the actuator plate engaging means, whereby upon moving of the draw plug rearwardly relative to the body, the actuator plates pivot about the pivot means and simultaneously shift the master jaw supports and counterweights to maintain positive grip on work when the body is rotated.

Machine tool chuck

A multiple work station machine tool turret has a highly responsive sensing control assembly which is free of environmental constraints and provides a distinct signal for each work station position correlatable with work station command data from a programmer.

Programmable turret-type machine tool

A turret index assembly has an air piston connected to a pawl to provide a cushioned stop therefor after its engagement with one of the teeth of a machine tool turret index plate.

Turret indexing assembly for machine tools

In a turning machine or the like having a tool for simultaneous axial and radial profiling of work, that invention which includes a rotatable spindle having a forward end and work support means on the forward end, circumferential profiling means rotatably mounted on the spindle and a carriage support mounted on the machine adjacent the spindle, a movable tool support carrier on the carriage support movable in a direction generally parallel to the spindle axis, a tool holder mounted in the tool support carrier for movement parallel to and radially of said spindle axis and the tool holder including longitudinal profiling means and including tracking means mounted between the circumferential profiling means and the longitudinal profiling means for simultaneously tracking both of the profiling means. The invention includes means in a turning machine or the like in which the tool axially and radially profiles work with at least two different patterns including, a first set of cooperating circumferential and longitudinal profiling means for forming a first control pattern, a second set of cooperating circumferential and longitudinal profiling means for forming a second controlled pattern, means for rotating the work on its longitudinal axis, means for moving the tool into engagement with the work and in the direction of the works longitudinal axis, means for operatively connecting said first and second sets of profiling means with said tool, and means for positioning said first set of profiling means relative to said second set of profiling means whereby when the work is rotated and the tool moved into engagement therewith, the work is profiled with at least said two different patterns according to the positioning of said first and second sets of cooperating circumferential profiling means.
