摘要:
A holding device for holding a stud, which includes a radially projecting flange in a securing position, comprises a collet component including a hollow tubular insertion section defining an insertion axis, and a clamping section operable to exert a radially inwardly directed clamping force for clamping the stud. A securing device is arranged on the insertion section and includes a securing sleeve formed of plurality of separate securing-sleeve sections that are radially movable relative to one another. A clearance space is defined between a bottom end of the securing-sleeve sections and a top end of the clamping section, and the clearance space is operable for holding a flange of a stud in the securing position.

A self-attaching fastener installation head and feed mechanism including a spring-biased L-shaped feed pawl which feeds a first nut in the feed passage adjacent the plunger passage on the upstroke of the die press. The feed pawl is pivotally supported on a slide bracket which includes a roller in the longitudinal axis of the feed passage which is biased against a central cam surface on the base and the base is interconnected to the nose member by removable pins. A spring biased nut restrictor is pivotally supported on the nose member, simplifying removal of a nut strip from the head and the installation head is more rugged in design and has fewer parts, reducing costs.

A device for driving a part, including a parts driver having a drive axis and a nosepiece including three jaws arranged uniformly about the drive axis and defining an axial drive passage therebetween. The jaws are resiliently biased toward one another and are transitionable between a first configuration to retain the part within the drive passage and a second configuration to allow the part to be discharged from the drive passage by the parts driver. An adjacent pair of the jaws defines a transverse parts feed passage intersecting the drive passage and being oriented at an oblique angle relative to the drive axis. Each of the adjacent pair of jaws defines a substantially symmetrical portion of the feed passage. A parts delivery conduit is pivotally coupled to the nosepiece and includes an end portion pivotable between a first position in which the end portion extends into the drive passage to aid in guiding the part into the drive passage and a second position in which the end portion is displaced away from the drive axis. The parts delivery conduit also includes a stationary end portion that is disposed proximately adjacent the pivotable end portion. The stationary and pivotable end portions define a substantially continuous parts delivery flowpath when the pivotable end portion is in the first position.
摘要:
There is disclosed an automatic nut feeding device comprising a body provided on a side surface thereof with a nut feeding hole, and a spring-plunger type conduction sensor mounted on a side of the body opposite to the nut feeding hole therein and adapted to be pushed by a nut, which is passed through the nut feeding hole to be fed into the body while laterally sliding.

The invention concerns an apparatus for automatically pressure fitting parts. In the apparatus, a work with part fitting holes is set on a work bench, and parts are fed to a predetermined position while being heated. The work bench is moved in an X- and a Y-direction to bring a part fitting hole of the work to a position underneath the predetermined position. A holder is then lowered, then is caused to take hold of the part at the predetermined position and pressure fit the part in the part fitting hole of the work held below, and then is pulled upward out of the part having been pressure fitted and secured in the position in the part fitting hole. Parts may be fed while being vibrated with an ultrasonic wave instead of being heated, and then may each be pressure fitted while being vibrated in a part fitting hole of the work, followed by pulling the holder upward out of the part having been pressure fitted and secured in the position in the part fitting hole.

An installation tool, fastener, and method for installing the fastener are disclosed. The installation tool has control fingers which control the position of the fastener with respect to the plunger and workpiece to which the fastener is to be attached during the entire travel of the fastener from the entry into the installation tool to installation in the workpiece. The fingers are pivotally mounted to the plunger and travel with the plunger throughout the installation path. The fingers are adapted to engage the fastener in a displaced area on the fastener so that the fingers can control the fastener through installation of the fastener into the workpiece. The displaced area is positioned between the top and bottom of the fastener so that the fingers can maintain control throughout installation.

In a nosepiece/receiver assembly having a housing for receiving a part, a removable jaw mechanism that is mounted for pivotable movement against a biasing spring. The jaw member has a contoured surface for holding a part received by the nosepiece/receiver assembly when the jaw member is in a part holding position. The jaw member includes channel at one end for enabling the jaw member to pivot about a securing member of the assembly to a part releasing position. The jaw member may consist of either two cooperating movable jaws or one separate jaw. The jaw mechanism also includes a resilient biasing device for urging the jaw member into a part holding position. The biasing device is in contact with both the housing of the nosepiece/receiver assembly and the jaw member, with at least a portion of the resilient biasing device being external to the jaw member to allow easy replacement of the biasing device. The biasing device is positioned to minimize the chance of breakage of the jaw.
摘要:
An apparatus for automatically causing the end face of a self-piercing nut (N) to function as a punch for piercing a metallic panel (P) laid on a caulking die (1) so that the nut is fixed to the panel. The apparatus has a pair of gripping fingers (31, 32) attached to the opposite sides of the lower end of a striking punch (2), and has a workpiece butting leg member (25) extending in parallel with a vertical bore (4) formed through a slide guide (3). The leg member (25) is attached to and depends from the bottom surface of the slide guide (3), so that the punch (2) holding the nut (N) by means of the gripping fingers (31, 32) will penetrate the slide guide (3) and then descend along the leg member (25), until the nut punches and is secured to the metal panel (P). Thus, the self-piecing nut (N) can be fixed to any bent bottom of or any narrow recess in the metal panel (P).
摘要:
A method for assembling a part, such as a spool valve into a bore of a body, such as a transmission valve body. A vacuum means creates suction within the bore in the direction of insertion of the spool valve. A gripper tool attached to a robotic arm supports the spool valve with a light vacuum pressure and maneuvers the spool valve, aligning it sufficiently close to allow the suction in the bore and gravity to pull the spool valve free of the suction of the gripper tool and into the bore.
