  • Patent number: 5459915
    Abstract: The invention relates to improvements in the multiple spindle rotary indexing machine tool systems of the prior art. Traditionally, such machine tool systems include a base and an upstanding vertical column which houses a plurality of machining stations each equipped with two-axis tool slides. In addition, the base supports a rotatable worktable, which carries a number of work-holding spindles. As the worktable rotates, these spindles are indexed through successive machining stations where a variety of operations are performed. In accordance with the invention, a spindle position measurement unit is provided to dynamically measure the exact location of each spindle indexed to position at a modified machining station. A computerized numerical control system calculates spindle position errors based on the position information provided by the measurement unit and offsets tool slide position commands to compensate for those errors.

  • Patent number: 5398395
    Abstract: Apparatus for applying a sleeve of heat-shrink material (a "band") to a container comprises a rotary drum having a plurality of upstanding heads. A web of banding material is intermittently advanced and lengths cut off, each cut length being held by fingers in the path of a gripper head mounted on the rotary drum. Each head has forward-facing vacuum port through which air is drawn on a timed basis, so that a band 30 will be picked-up and held by one side face as the gripper head passes the fingers. The resilience of the banding material allows the band partially to open out as it is transferred by the gripper head. The rotation of the drum is synchronized to advancement of the containers, so that a held band is rolled on to the top of a container, the container serving to assist in the opening-out of the band, whereat the band is released by the gripper head.

  • Patent number: 5097577
    Abstract: An intermittently rotary workpiece-holding table has operating units that move vertically relative to the table. The operating units are controlled by vertically swinging levers that are driven vertically at one end and at their other ends control the operating units. The levers pivot about fulcrums, each lever having two fulcrums spaced apart along its length. During a first portion of movement of the lever, that fulcrum is operative which gives the most rapid vertical movement to the operating unit. Then the first fulcrum becomes inoperative and the second fulcrum becomes operative, whereupon the speed of vertical movement of the operating unit slows, as for example for the performance of a work operation.

  • Patent number: 4036484
    Abstract: Advancing mechanism for a series of fixtures having collets for workpieces are actuated by a fluid actuated double-acting cylinder to lock and unlock the collet. A driven rotatable table has a plurality of equally spaced fixtures mounted thereon which are advanced seriatim to a plurality of machining stations where work is performed thereon. Each advancement moves a fixture to the unloading and loading station where the collet is released, the finished workpiece removed and a workpiece to be machined placed within the collet. The double-acting cylinder was actuated by the fluid to release the collet and after a workpiece was placed therein a reversal of the fluid clamped the collet in secured position. The collet is locked and unlocked by the operation of a transverse pin in a sloping slot in a sleeve which is advanced over the collet to move the sections of the head into clamped position to hold the workpiece.

  • Patent number: 4007521
    Abstract: This invention relates to an automatic precision apparatus which includes an elongated rotatable central shaft concentric with and encased by a fixed outer cylinder. A rotary workpiece table is fixed to the central shaft adjacent one end of the central shaft, and a round tool holder table is fixed to the cylinder adjacent one end of the cylinder and disposed in spaced relationship with the rotary table and in parallel arrangement with the rotary table. A plurality of spaced tool holders are disposed around the round table, and a plurality of equally spaced workpiece holders are disposed on one surface of the rotary table facing the round table. Each tool holder is precisely aligned with a respective one of the workpiece holders and is alignable with every other one of the workpiece holders.

  • Patent number: 4004333
    Abstract: A rotary turret numerically controlled punch press is provided with a discharge station at from a punching station. A part is clamped in the turret, separated from a larger workpiece and then rotated with the turret to the discharge station. A transfer arm is slaved to the NC punch press and engages the part at an exact attitude and position relative to a reference point on the part and transfers the part to a rotary chuck. The part is placed in the chuck at an exact attitude and with the reference point at the axis of rotation of the chuck.Four rotary chucks are provided on a rotary turret contouring apparatus. The turret is rotated to position the part at a cutting station.A band saw is provided with rotary guides for changing the angle of the saw. While the part is rotated and linearly translated toward and away from the saw by the contouring apparatus, the saw cuts a peripheral shape on the part with the blade changing its angular attitude where necessary.

  • Patent number: 3990133
    Abstract: A multi-station machine tool wherein the bed of the frame supports two spaced-apart upright columns and the columns support an indexible shaft for a turret which is disposed between the columns. The turret has several sets of clamping jaws for elongated rod-shaped workpieces which are introduced and removed at a first station or which are introduced at a first station and removed at a second station. The number of stations may greatly exceed two, and each column supports several spindles including at least one rotary and axially movable tool spindle and at least one axially movable and preferably rotary work spindle. Each spindle in one of the carriers is coaxial with a spindle in the other carrier, and the turret indexes the workpieces in such a way that they come to rest between successive or selected pairs of coaxial spindles.

  • Patent number: 3974553
    Abstract: Automatic machinery for performing multiple operations on different parts of workpieces includes an incrementally rotating, workpiece supporting turret provided with three workpiece supports. Upon rotating of the turret, a workpiece loaded on a support located at a first position is indexed about the axis of the turret to a second position at which a first operation is performed thereon, then to a third, idle position. Continued rotation of the turret results in an index of the workpiece to the first position, then again to the second position at which a second operation is performed thereon. After the next index to the third position, the workpiece is unloaded from the support. As the turret is indexed, the workpiece is rotated relative to the turret whereupon the workpiece is oriented differently each time it reaches the second position causing the operations to take place on different parts of the workpiece.
