  • Patent number: 11648651
    Abstract: The installation tool for a wire thread insert includes: a drive unit which provides a switchable rotation movement between a first and a second direction, a mandrel body with a drive section for rotating the mandrel body and with a drive section for rotating the mandrel body and with a thread section onto which the wire thread insert can be screwed or rotated on, an installation blade as well as a torque clutch consisting of a form-fit and force-fit clutch upper and lower parts engaging each other, of which the upper part is connected with the drive unit in a torque-proof manner and the lower part is connected with the mandrel body in a torque-proof manner. With a decoupled relative rotation between the clutch parts, caused by exceeding a limit torque between the clutch parts, relative movement between the mandrel body and the installation blade can be generated.

  • Patent number: 11420311
    Abstract: An insert insertion tool includes a mandrel on which an insert is mounted, and a coating member. The coating member is configured to apply ink to a rear end of the insert on an opposite side of a tip end of the insert that first enters a tap hole. Accordingly, the insert inserted into the tap hole stands out on a surface of a workpiece, and a user is capable of visually recognizing whether or not the insert has been inserted into the tap hole. Thus, the confirmation work becomes easy, and it is possible to improve the work efficiency.

  • Patent number: 9643304
    Abstract: An insertion tool is used to insert a threaded coil insert into a threaded opening of a support structure. The tool includes a rotatable mandrel body having an axial longitudinal passage and a projection slot. A plunger is disposed in the passage forward of a spring which urges the plunger forward. The plunger in turn urges a drive projection. A front end of the plunger includes an inclined surface that slidingly and inclinedly engages an inclined surface of the drive projection. The urging of the drive projection by the plunger along their respective inclined surfaces causes relative sliding movement of the drive projection so that the drive projection translates linearly through the projection slot in a direction perpendicular to the longitudinal passage.

  • Patent number: 6860173
    Abstract: A tool for installing a helical coil insert in a tapped hole formed in a workpiece includes a tubular body having a bore extending along its axis, a mandrel coaxially disposed in the bore of the tubular body, a motor for rotating the mandrel, and an air cylinder for applying an axial force to the mandrel. The tubular body includes a recess at one end for carrying a helical coil insert in alignment with the bore. An opening in the tubular body allows a user access to the recess. The tubular body is moveable to position the helical coil into selective engagement with the mandrel, whereby rotation of the mandrel installs the helical coil insert a selected depth in the tapped hole of the workpiece. In addition, the mandrel slides axially within the bore of the tubular body to remove the tang from the helical coil insert upon installation of the helical coil insert in the tapped hole.

  • Patent number: 6704985
    Abstract: A single component tool for installing a threaded insert with locking keys in a tapped bore. The tool has no moving parts and enables simultaneous driving of the locking keys into the tapped bore, flush with the upper edge of the threaded insert in the tapped bore. The tool has a pilot that is inserted into the inner bore of the insert and a plurality of tool keyways for receiving the locking keyways of the insert. Bores are provided in one face of the tool for retaining and aligning the locking-keys while the keys are driven into the tapped bore. A timing mark provided on the tool aids in aligning the tool to simultaneously drive the locking keys flush with the upper edge of the threaded insert.

  • Patent number: 6704984
    Abstract: A prewinder apparatus for selective attachment to an installation tool is provided. The prewinder apparatus includes a support structure selectively attachable to the installation tool, a prewinder attached to the support structure, the prewinder having first and second threaded apertures, and a mandrel having a threaded end and a coupling end. The threaded end is in threaded engagement with the second threaded aperture. The coupling end is in selective operable engagement with the drive tool, whereby the drive tool rotatably drives the mandrel relative to the prewinder for rotatably driving the helical coil insert through the second threaded aperture to prewind the helical coil insert.

  • Patent number: 6513217
    Abstract: An apparatus for replacement of a starter cord in a small motor starter cord assembly. A spindle is mounted within a hub with a handle at one end and a tool fitting at the other end. The hub includes at least two arms. The arms attached to the hub are of a size to fit within a pull cord apparatus that is removed from a small motor and inverted. The arms extend to secure against the side of the pull cord apparatus. At the end of the spindle opposite a handle, a variety of tools can attach to the spindle to fit within or fit over the spring-mounted reel in a starter cord apparatus. The tool is placed within the starter cord apparatus. The arms extend to secure it in place. The tool is fitted to the reel and the handle rotated to wind the reel to a fully wound position so that a new starter cord can be threaded into the reel and tied off. The tool is then released to allow the spring to unwind hence, winding a replacement cord onto the reel.

  • Patent number: 6421899
    Abstract: An extraction and adjustment tool for tangless helically coiled wire inserts according to the invention includes a mandrel with a leading portion having a tooth for reception in a recess of the insert for left-hand rotation of the insert. An end opposite the leading portion is received in a bushing of a handle portion for connecting the mandrel to the handle. Left-hand rotation of the handle contracts the insert about the leading portion of the mandrel to facilitate adjustment or removal of the insert.

  • Patent number: 6321433
    Abstract: A prewinder mandrel including an elongate shaft having a threaded lead end, a slot dividing the lead end into first and second end portions, and a pair of opposing beveled edges on the first end portion. A first drive edge is located between the first and second beveled edges, a second drive edge is located on an outer edge of the second end portion, and an inclined ramp extends along the second end portion from the leading edge towards the slot. The mandrel may part of a prewinder tool for installing helical wire inserts that includes a drive mechanism coupled to the mandrel shaft and a threaded nozzle through which the shaft extends. The shaft includes a threaded intermediate region for engaging the threaded nozzle to drive the mandrel at a predetermined pitch. The lead end is inserted into a wire insert, the shaft rotated to advance the insert over the lead end until the tang engages a first beveled edge and is seated within the slot.
