A method and rivet apparatus comprise a rivet block, the rivet block comprising a rivet block, a pin bore, and a rivet feed bore. The rivet block is comprised of a top end and a bottom end. The pin bore includes a top end and a bottom end and is disposed within the rivet block. The pin bore extends from the top end to the bottom end of the rivet block and guides a rivet pin that slides downward within the pin bore to push a head of a rivet into a workpiece. The rivet feed bore includes a top end and a bottom end and is disposed within the rivet block. The rivet feed bore extends from the top end to the bottom end of the rivet block, accepts the rivet at the top end of the rivet feed bore, and guides the rivet to the bottom end of the rivet feed bore. The rivet feed bore intersecting the pin bore between the top end and the bottom end of the pin bore at an oblique angle.

In order to mill, drill, saw or the like in the offshore sector, subsea processing machines are used which comprise a tool holder with a change hub for receiving at least one rotary tool, such as for instance a milling cutter, saw, drill or the like. The tool holder preferably has a carrier body for receiving the tool hub, wherein the latter comprises a hub flange for receiving tools. The preferably centric hub ring of the change hub can be arranged on the carrier body of the tool holder and can be connected to the tool holder in such a manner as to be able to be detached and clamped by means of at least one locking apparatus.

The invention relates to a clamping device and is designed for releasably clamping a supporting body on which a workpiece can be arranged. The clamping device has a main body with receiving bores each for receiving a clamping bolt of the supporting body. Each clamping body can be moved linearly along the longitudinal axis thereof between a clamping position and a release position. The movement from the release position into the clamping position and/or conversely from the clamping position into the release position can be effected by means of an actuation device. Each clamping body has a clamping end which protrudes into an associated receiving bore in the clamping position. The longitudinal axes of the clamping bodies form a plurality of intersection points in a common projection plane parallel to which the longitudinal axes extend. In a preferred embodiment, at least three or four intersection points are formed. More particularly, four clamping bodies can be present, each with a longitudinal axis, wherein four intersection points are formed, in each of which two of the available longitudinal axes intersect.

A cutting tool assembly includes a tool shank having a coupling opening, and an insert holder having an insert body to which an insert is coupled and detachably attached. A coupling protrusion protrudes from one surface of the insert body and is detachably coupled to the tool shank. Located on the coupling protrusion are a tapered contact portion which comes into contact with the coupling opening and provides a fixing force to fix the insert holder to the tool shank, and a contact surface at a rear end of the tapered contact portion which couples to a fastening member.

A device adapted to releasably lock with a bolt, the device comprising a front cover having a cavity which extends from the front cover to a rear portion of the device, wherein the cavity is adapted to receive the bolt with mounting concave portions for mounting the bolt in the cavity; a locking mechanism comprising a first group of locking shape, wherein the first group of locking shapes is moveable between a first position and a second position, wherein the first position is in the cavity, and the second position is in a corresponding first group of locking shape recesses. A moveable block comprising the first group of locking shape recesses; wherein disengagement of the first group of locking shapes is activated by movement of a release plate thereby allowing the first group of locking shapes to retract from the cavity into the first group of locking shape recesses.

A device according to the present disclosure is a workpiece retaining device 10 that retains a retained portion 110 of an axial-directional end portion of a workpiece 100 that is cylindrical. The workpiece retaining device 10 includes a core member 32 that is round and that comes into contact an inner perimeter face of the retained portion 110 of the workpiece 100, a pressing member 33 that presses an outer perimeter face of the retained portion 110 of the workpiece 100 to an inner side in a radial direction, and an aligning member 44 that, upon a pressing force from the pressing member 33 acting thereupon, allows the core member 32 to move in the radial direction, in accordance with a magnitude and a direction of the pressing force.

A work tool or a wear member includes a working portion or a wear portion, and a shank extending from the working portion or the wear portion, defining a longitudinal axis, and a first lock receiving groove that defines an axis of rotation that is perpendicular to the longitudinal axis of the shank.

A bit holder is provided including a tool bit receiver body operably configured to receive at least a portion of a tool bit, a retention element configured to retain the tool bit engaged within the tool bit receiver body, a release configured to disengage the retention element enabling removal of the tool bit, a drive element operably coupled to the tool bit receiver body and configured to transfer axial rotation from a driving tool to the tool bit receiver body, and a sleeve disposed around at least a portion of the bit holder and configured such that the tool bit receiver body rotates independent of the axial rotation of at least a portion of the sleeve.
