An end effector provides one up assembly drilling through mated components, including a panel, by preloading the components. The end effector includes a drill and clamp dispenser for temporarily inserting and removing expansible single-sided clamps at various pre-drilled locations in the panel. In one method, pilot holes are first pre-drilled into mated components, for example an aircraft wing panel and a wing rib or spar; an initial pilot hole location is identified, and an expansible clamp is inserted into a pilot hole adjacent a desired initial fastener hole location. The clamp is torqued, causing its expansion for preloading the wing panel and rib and/or spar components under a predetermined load. The fastener hole is then drilled, the end effector untorques and removes the clamp and identifies a second (and/or next) pilot hole location, and the process is replicated.

A wheel hub special drilling device comprises a main shaft transmission device, which has a transmission mechanism base and a transmission mechanism mounted on the transmission mechanism base, wherein the transmission mechanism comprises an X-axis transmission mechanism, a Y-axis transmission mechanism and a Z-axis transmission mechanism which are used for respectively moving a main shaft in three vertical axial directions; a main shaft, which is mounted on the vertical Z-axis transmission mechanism; a drilling tool, which is mounted on the main shaft and is rotationally driven by the main shaft; a clamp device, which is used for clamping and fixing a wheel hub to be processed.

The invention concerns a drilling device (1) and a method for drilling holes in a stack of material (100). The drilling device is provided with clamping means (23, 26) for clamping the material, a hollow drill (10) with an internal channel and a drive (3) for the hollow drill. The drilling device is further provided with connecting means (4) for cooling means, that are arranged for conducting gas through the internal channel, and suction means (51) for suctioning drilling debris. The drilling shaft is provided with a cut out, that runs in longitudinal direction along the drill shaft and forms a discharge channel for the drilling debris.

The invention also concerns a machine for machining and assembling window coverings, such as pleated blinds, comprising one or more drilling devices according to the invention.

A tool coupling extends along a longitudinal axis and has a first component, a second component, and a clamp for fastening the first component to the second component. The first component has a male clamping portion, the second component has a female clamping portion, and the clamp is located in an inner cavity of the second component. The male clamping portion has a first abutment region located axially rearward of a first plane perpendicular to the longitudinal axis, the inner cavity has a second abutment region located axially forward of the first plane, and the first and second abutment regions face towards the first plane. In a fastened state, a clamp first engagement region of the clamp makes clamping contact with the male clamping portion's first abutment region, and a clamp second engagement region of the clamp makes clamping contact with the inner cavity's second abutment region.

A technique facilitates performance of a machining operation on a component, e.g. a flange. An embodiment of the technique may employ an externally mounted flange facing machine having an external housing with a hollow interior therethrough. The externally mounted flange facing machine may further comprise a plurality of clamping feet mounted to the external housing and oriented for external engagement with the flange. A surface facing arm assembly may be movably mounted to the external housing for rotation in the hollow interior. Additionally, a tool carrier assembly may be movably mounted to the surface facing arm assembly. A feed assembly may be coupled with the tool carrier assembly to drive the tool carrier assembly linearly along the surface facing arm assembly as the surface facing arm assembly rotates in the hollow interior.

A tool holder has a holder body, a first clamping member, and a first fastening member. The holder body includes a fixation portion and a mounting portion located rearward of the fixation portion. The fixation portion has a front fixation surface facing in a forward direction, a cylindrical fixation bore opening out to the front fixation surface and extending rearwardly therefrom, and a longitudinally extending primary slot connecting the fixation bore to a fixation envelope surface. The first clamping member occupies a first clamping bore and traverses the primary slot. The first fastening member occupies a first fastening bore which intersects the first clamping bore and opens out to the front fixation surface. The fixation bore has a fixation bore first primary diameter which decreases and increases when the first fastening member is rotated in first fastening and first unfastening directions about the first fastening member axis, respectively.

A machining system configured to reduce spring back following machining operations comprising a machining tool and a spring back control system. The spring back control system comprises a number of force generators and a number of force loaded members coupled to the number of force generators, each force loaded member of the number of force loaded members comprising a material contact surface. The material contact surface is a roller, wherein the machining tool is independently moveable relative to the spring back control system.

A method and apparatus for tapping into a pressurized multiple strings of coaxially situated tubulars for wells and/or platforms which have overturned wherein the tapping occurs underwater via a diver or remotely operated vehicle. The assembly includes a tapping tool connectable to the tubular via a saddle connection and an adjustable tapping clamp with adjustable support/locking feet, compression plate with view ports, and angularly adjustable hot tapping system, along with a drill/saw system.

A wheel hub special drilling device comprises a main shaft transmission device, which has a transmission mechanism base and a transmission mechanism mounted on the transmission mechanism base, wherein the transmission mechanism comprises an X-axis transmission mechanism, a Y-axis transmission mechanism and a Z-axis transmission mechanism which are used for respectively moving a main shaft in three vertical axial directions; a main shaft, which is mounted on the vertical Z-axis transmission mechanism; a drilling tool, which is mounted on the main shaft and is rotationally driven by the main shaft; a clamp device, which is used for clamping and fixing a wheel hub to be processed.

This accessory, for a hand held drill, turns the drill into a portable drill press. To use this portable drill press, place the drill bit where you want it. Lean the drill forward until the base slides under the metal your drilling. The base is a lever and the drill and bit swings off it. The base holds the drill in place at a angle. When the drill is pulled straight, everything tightens up. The metal and the drill bit are pushed together with leverage. Turn the drill on and drill the hole by just holding the drill straight. This portable drill press is faster and easier to use, than drilling by hand.
