The tool can include a tang keeper which can be positioned behind the tang of a helical insert which is installed in an aperture, and a pushing member which can be moved to push the tang against the keeper and hold the tang against the keeper while breaking and removing the tang by manipulating the tool.

A tool for installing or removing a wire thread insert. This tool includes a spindle body having an actuator which can be moved axially therein. The actuator interacts with an entraining blade. By the axial movement of the actuator, the entraining blade can be extended out of the axial recess and retracted back into it.

Wire thread insert consisting of a body with a plurality of helically wound windings, in which the plurality of helically wound windings comprises a first end winding and a second end winding which define the body at opposite axial ends, the first end winding has a first integral form-fitting means in a first end section and the second end winding has a second integral form-fitting means in a second end section, so that in an installed state of the wire thread insert a form-fit rotation-inhibiting connection with an adjacent component structure can be produced via the first and the second integral form-fitting means respectively.

The crimping plier of the present invention includes an abutting member, a crimping member, a crimping tooth member, a cover plate, and a driving mechanism. The abutting member has a crimping hole for placing the connection terminal. The crimping member is adjacent to the crimping hole, and one end of an elastic element abuts against the crimping member. The crimping tooth member is fixedly disposed on the crimping member. The cover plate is connected to the abutting member and covers the crimping member, and the cover plate is also in contact with the other end of the elastic element. The driving mechanism is in contact with the crimping member to push the crimping member and the crimping tooth member. When the crimping member and the crimping tooth member slide, the elastic element provides an elastic force between the crimping member and the cover plate.

An automatic installation machine, which is connectable to a tool so as to install a wire thread insert in a thread bore, includes a drive unit providing movement between a first and a second rotation direction, a setting spindle in rotation coupling with the drive unit so that during a transmission of a rotation movement from the drive unit, the setting spindle is displaceable in longitudinal direction independent of the rotation movement. A first pneumatic cylinder has a movable piston oriented parallel to the longitudinal direction of the setting spindle and coupled with an offset with the setting spindle so that the setting spindle is axially displaceable by the pneumatic cylinder. An actuating mandrel is arranged within the setting spindle and is driven rotation free, and the installation machine includes a tool chuck via which the tool for installing the insert is connectable with the setting spindle.

A device for extracting a deeply embedded helical coil is provided. The device includes a shaft, the shaft comprising a proximal end and a distal end; and a blade coupled to the distal end of the shaft, wherein the blade is configured to traverse into a mounting hole to engage the deeply embedded helical coil free of contact with a side of the mounting hole and wherein the deeply embedded helical coil is at least three to five thread pitches below a surface of the mounting hole.

The invention relates to crimping pliers and a method of assembling crimping pliers. According to the invention, a coupling of a crimping pliers head (32) to a crimping pliers actuation assembly group (1) is provided by coupling recesses (45, 46) and coupling elements (22, 23) arranged in the coupling recesses (45, 46). A re-exit of the coupling elements (22, 23) from the coupling recesses (45, 46) is prevented by a spring device which is effective between the die halves (35, 37) for biasing the movable die half (37) in opening direction.

A device is provided for inserting coil inserts into threaded holes. The device includes an insertion tool having a manipulator end which is configured to receive and hold a coil insert, and which is operable to apply a torque to the coil insert to screw the coil insert into a threaded hole when presented thereto, the manipulator end having an insertion axis which is coincident with the axis of the coil insert when held by the manipulator end. The device further includes a tool support to which the insertion tool is mounted, the tool support being fixable to an end of a robot arm whereby the manipulator end is presentable by the robot arm to the threaded hole for insertion therein of the coil insert.

A driver tool apparatus is provided for the secure gripping, driving insertion, and release of a broad range of connector and/or fixation elements such as screws or bolts. These driver devices can be utilized for a broad range of applications in many fields. The driver tool, in some embodiments, may include a driver shaft; one or more driver elements protruding from the driver shaft and having a base region proximate the driver shaft and a distal region away from the driver shaft, wherein each driver element includes one or more pins suitable for inserting into a socket having one or more inside walls; and one or more securing features on each driver element.

In a method for installing a key locked insert to a workpiece, the workpiece has a hole open to a first surface. The method includes: threading an insert body into the hole; threading a first portion of a mandrel into the insert body; after the threading of the first portion into the insert body, mating a second portion of the mandrel with an actuator; and using the actuator to extend an anvil relative to the mandrel to drive keys of the insert through a thread of the workpiece hole.
