The present invention concerns a device for removing a fastener (12) installed in the hole of a structure, said device comprising: a base (20) capable of being fastened to the structure, and a guiding device, defining a cylindrical passage (78) and including: a support (48) equipped with a first removable assembly means with the base in a first assembled configuration; a blocking element (50), mobile relative to the support; and a device (83, 84) for adjusting an axial position of the blocking element relative to the support, to a blocked configuration corresponding to the engagement of said blocking element with the fastener (12), so as to prevent the rotation of said fastener relative to the structure.

An apparatus for clamping a robotically controlled tool to a workpiece comprises a tool support mountable on a robotic arm and configured to support the tool, a plurality of clamping modules, each of which includes at least one vacuum cup arranged to clamp the tool support to the workpiece, and an adjustment mechanism configured to adjust the position of the tool support relative to the workpiece.

Disclosed is a core drill guide apparatus for providing a guide for a core drill apparatus to drill into a substrate to form a removable core. The apparatus includes an elongate body with an outer surface and inner space, having an entrance end, an exit end and side walls, a distance between the ends defining a length or height of the elongate body and a width. An passageway extends through the elongate body from entrance to exit end, adapted so that in use, it provides sliding receipt of a fastening system to clamp the apparatus to an outer surface surrounding a first hole in a substrate, allowing the apparatus to abut the outer surface and drill out a core in the substrate underneath and surrounding the first hole. A corresponding guide method and fastening system are also disclosed.

A template kit for assisting with the drilling of holes and the mounting of objects to a planar surface. The template kit includes an impactor, a plurality of punch heads removably securable to the impactor, and a sheet of material having a first side and a second side. The first side includes a first adhesive that can releasably secure the object to be mounted. The second side includes a second adhesive that can secure the device to a wall or other planar surface. The second adhesive has increased adhesive strength relative to the first adhesive. Each punch head includes an inner and outer edge that can cut a disc member from the sheet of material, wherein the impactor drives the punch head through the sheet of material. In use, the disc members are secured to a wall and serve as a guide for drilling a hole to hang the object.

Disclosed are systems and devices for controlling the closing of a door. A head unit is to be installed in a doorjamb, comprising a chamber filled at least in part with a shear thickening fluid. A piston is connected to a cap and configured to exert pressure against the shear thickening fluid in response to a force applied to the cap. The systems and devices provide an adjustable design that resists door slamming and aggressive closure, serving as a safety device as well as noise, damage and pet control around doors (preventing closure if desired). An install kit provides exact location, depth control and guide to place over the head unit to tap it into place with a hammer.

According to one implementation, a hole finishing tool includes a reaming cutter and a holder. The reaming cutter has a first detaching structure. The first flow path for ejecting cutting oil is formed inside the reaming cutter. The holder has a second detaching structure. The second detaching structure is detached from and attached to the first detaching structure. The second flow path for supplying the cutting oil to the first flow path is formed inside the holder. The holder has a shank. The shank is held by a tool rotating device. The holder has a sliding portion. The sliding portion has no back taper. The sliding portion is inserted into a positioning bush and slid inside the positioning bush. The sliding portion has a concave portion for storing lubrication oil.

A tool for creating a wall opening. The tool includes a hole saw; and a centering jig having a center axis, where the centering jig is constructed as a centering ring, into which the hole saw can be pushed at least partly, and in that both the hole saw and the centering ring have on their circumference an opening such that this can be pushed transverse to the center axis completely onto a line.

A system for processing a workpiece includes a robotic manipulator and an end effector coupled to a working end of the robotic manipulator. The end effector includes a machine tool and an end-effector vacuum clamp that is coupled to the machine tool. The end effector is releasably coupleable to a surface of the workpiece. A processing force is reacted through the end effector and to the workpiece.
