  • Patent number: 9527135
    Abstract: In a bar puller, pins mount serrated rollers to pivoting arms, which are mounted by additional pins to a bar puller body. The body houses movable cups positioned to compress springs in response to pivoting motion of the pivoting arms. A cover retains the springs and cups in the body. In a manufacturing process where elongated stock material needs to be positioned automatically, such as in a CNC turning center, the bar puller manipulates the elongated material in the machine by holding it rigidly so that the bar puller can move the elongated material on the axis of elongation. This is accomplished by forcing the end effectors over the material, which separates the end effectors by pivoting the arms. The geometry of the pivoting arms causes interaction with the cups and springs to generate an opposing spring force to separate the end effectors.

  • Patent number: 5535653
    Abstract: A bar stock supporting and feeding apparatus which includes first and second series of bar stock support members centered about a longitudinal axis and movable with respect to the axis to rotatably engage a length of bar stock. An adjustable stop mechanism is provided to quickly adjust the apparatus to rotatably support bar stock of different diameter. A loading and unloading mechanism is provided which does not require that an operator's hands be placed dangerously close to the apparatus. A bar stock feeding apparatus is provided with a similar gear system for engaging the bar stock and feeding it into an adjacent machine tool. A fail-safe mechanism prevents disengagement of the support apparatus in the event of a loss of fluid pressure in the system.

  • Patent number: 5322000
    Abstract: A material holding and guiding device of automatic lathe has a base with one end provided with an arm frame and another end provided with a reciprocating set. A receiving and retaining set is mounted pivotally on the arm frame in a manner that the bottom of the receiving and retaining set is coupled with the reciprocating set. The receiving and retaining set has an inner annular body and an outer annular body. The inner annular body is axially provided with a through hole which is used to accommodate therein the material to be lathed and which is provided at each of two ends thereof with a ring sleeve. The motion of the reciprocating set causes the receiving and retaining set to make a swing of a predetermined angle so as to force the ring sleeves located at both ends of the through hole of the inner annular body to hold the material stably in a manner that the material is capable of turning synchronously with the inner annular body.

  • Patent number: 5046226
    Abstract: The convertible bar-puller provides a convertible tool for automatic lathes. This tool has two main parts; a housing head and a shank. The housing head is attached to the shank using an adjustable connection means allowing the housing head to be positioned vertically with respect to the shank. The shank includes flat sides and radius corners to be received in either an internal tool housing or an external tool housing on the turret of the lathe. Positioning of the head on the shank in a first position fixed with the shank even with the upper end of the housing head adapts the tool for an external tool housing while fixing the head in the middle of the shank adapts the tool for an internal tool housing. Jaws for engaging the object to be machined extend forwardly from the head and have an adjustable jaw opening. The jaws each comprise a finger portion and an end portion, the end portion received in a circular groove on a jaw setting screw internal to the head.
