The invention relates to a system and method for changing liners of a mill, the configuration of which allows the automated robotic manipulation of liners of mills for ore grinding in comminution processes. The configuration and operation of the system allows the task of manipulation to be improved, having a greater degree of freedom and/or flexibility in its movements, thereby providing a greater degree of certainty and efficiency to the method and thus optimising the time that the mill is halted for maintenance, and also preventing the risks to which maintenance staff may be exposed. The system comprises at least one support structure, at least one system for supplying and moving liners, at least one robotic manipulator system for manipulating the liners, at least one liner manipulation tool, at least one artificial vision system, and at least one control system.

A method of manufacturing a composite including a sun gear and a planet carrier for a planetary gear unit, the sun gear and the planet carrier being manufactured as separate components and then joined together. The two components are joined together by establishing, by deformation, a form-fit connection between the two components.

An assembly for separating a coupling hub from a shaft of a rotating machine includes a support frame sub-assembly that structurally supports the assembly and the coupling hub. A vertical adjustment sub-assembly is structurally supported by the support frame sub-assembly. The vertical adjustment sub-assembly adjusts the elevation of a puller sub-assembly from the surface of the Earth. The puller sub-assembly couples to the coupling hub and separates the coupling hub from the shaft.

Provided is a high-quality electric motor which can be manufactured at a high yield rate. An electric motor comprises a stator which is housed in a motor case, and a rotor which is provided with a shaft and a rotor body section. The shaft is rotatably supported by the motor case, and the rotor body section has a ring magnet disposed inside the stator. A magnet cover into which the rotor body section is inserted has a circular cylinder section which covers the outer peripheral surface of the ring magnet, a turned-back section which is in contact with an end surface of the rotor body section, and a fastening end section which is fastened to a flange section provided to the shaft so as to cover an end surface. An engagement latch section engaging with the rotor is provided to the turned-back section.

A metallurgical technology probe insertion calibration method employing visual measurement and an insertion system thereof are provided. A vision sensor (5), a cylindrical rod (1), and a metallurgical technology probe (2) are used to construct an agreed region (6). In the agreed region (6), the vision sensor (5) acquires relative positions and orientations of the cylindrical rod (1) and the metallurgical technology probe (2), and an acquired position and orientation result is used to control a driving device (3) to insert the cylindrical rod (1) into the metallurgical technology probe (2). To improve the accuracy and reliability of the insertion, a standard probe (7) and a fixing device (4) are used together to perform effective calibration on an initial position, orientation, and axis in the insertion.

An installation tool assembly includes a workpiece and a tool. The workpiece includes a first wall having an aperture and a second wall spaced from the first wall relative to a first axis to present an access point therebetween. The installation tool assembly includes a fastener disposed in the aperture of the first wall at an initial position. The fastener includes a hole and a fastener locking feature disposed inside the hole. The tool includes a tool locking feature that is configured to engage the fastener locking feature to secure together the fastener and the tool in the initial position. The tool is operable to pull the fastener farther through the aperture into an interference fit with the first wall in an installed position. A tooling assembly includes the tool and the fastener. A method of installing the fastener to the workpiece uses the tool.

An apparatus includes a body, a shaft assembly, and an end effector. The shaft assembly includes an outer tube, a proximal inner tube member, a distal inner tube member, and an acoustic waveguide. The end effector includes an ultrasonic blade and a clamp arm. A first portion of the clamp arm is pivotably coupled with a distal end of the outer tube. A second portion of the clamp arm is pivotably coupled with a distal end of the distal inner tube member. The outer tube is configured to removably couple with the body and the distal inner tube member is configured to removably couple with the proximal inner tube member such that the outer tube, the distal inner tube member, and the clamp arm are configured to removably couple with the body and the remainder of the shaft assembly and end effector as a unit.

The present invention relates to a hydraulic extrusion tool for extruding a rotor shaft for a turbomachine, and a corresponding method. The turbomachine has a structure that is fastened to the rotor shaft by a press fit. The extrusion tool has a first tool part that is configured for the purpose of being arranged on a first side of the structure, and which has a coupling mechanism that is configured for the purpose of coupling the first tool part to the structure, in such a way that the first tool part and the structure cannot move away from each other, at least in one direction along an axis of the rotor shaft; and an induction device that is configured for the purpose of heating the structure by induction in the region of the press fit.
