Milling device for prosthetic surgery comprising a milling tool rotating about a milling axis, and a handling body. The handling body is provided with a drive rotating rod which develops along a longitudinal axis of linear rotation and is connected to the milling tool in order to make the milling tool rotate about the milling axis.

A workpiece accumulator system for a stamping machine includes linear actuators, nesting blocks, exit rails, and a first controller. The nesting blocks are disposed on moveable members of the linear actuators and arranged to vertically stack workpieces being fabricated by the stamping machine. The first controller communicates with a second controller that controls the stamping machine. The first controller controls the linear positions of the linear actuators to retract the nesting blocks from an initial position to accommodate placement of the one of the plurality of workpieces in a stack on the nesting blocks. The linear actuators are controlled to retract the nesting blocks to fully retracted positions to place the plurality of workpieces in the stack onto the exit rails when a quantity of the plurality of workpieces in the stack is equal to a desired quantity.

The machining station can include a table; at least three robots each having a multi-axis mover secured to the table, and a gripper opposite the table, the robots being interspaced from one another on the table; and a controller. The controller controls the robots to hold a workpiece in a coordinated manner. The computer numerical command (CNC) machine-tool system machines the workpiece while the workpiece is held by the robots. The workpiece can be moved into and out from the machining station with a trolley which slidingly engages a trolley path formed within the table.

This application discloses magnetically coupled integrated probes and probe systems, attachable to the robotic arms of a remotely operated vehicle to perform both cathodic protection (CP) voltage measurements and ultrasonic testing (UT) thickness measurements at an underwater surface. The integrated probe system can include a spring for coupling to an ROV end effector. An ultrasonic probe is disposed within and extends from the sleeve housing. A magnetic carrier, flux concentrator, and gimbal surround a portion of the ultrasonic probe, and one or more electrically conductive legs extend from the front surface of the gimbal to function as a CP probe. The legs are arranged about the ultrasonic probe, which has a flexible membrane exposed at the front surface of the gimbal, such that during inspection, at least one leg contacts the surface and the ultrasonic probe is sufficiently proximate to provide substantially simultaneous CP and UT measurements.

A symmetrical tri-axial parallel spindle head capable of multi-directional fixed-point rotation, comprising three branch chains (2), a moving base (5), and a fixed base (1). A machining spindle (6) is fixedly connected onto the moving base (5). Each of the branch chains (2) comprises a servo motor (22), a branch chain rod (21), a lead screw (23), and a guide nut (25). The lead screw (23) and a linear guide rail (24) are provided in an inner cavity on one end of the branch chain rod (21). One end of the lead screw (23) is connected to the servo motor (22), the lead screw (23) passes through the guide nut (25), and the other end of the lead screw (22) is connected to the branch chain rod (21) by means a rotating pair. The guide nut (25) is mounted on the linear guide rail (24) and is rotatably connected to the fixed base (1) through a first support disc (26). The other end of the branch chain rod (21) is rotatably connected to the moving base (5) through a second support disc (28). The symmetrical three-axial parallel spindle head not only can enable the tool to achieve multi-directional fixed-point rotation around any point within a certain range of the internal space of the moving and fixed platforms merely by the parallel spindle head structure itself, but also can achieve multi-directional fixed-point rotation around the tool tip point; and the spindle head structure is symmetrical, and the motion characteristic is also symmetrical.

An apparatus for coupling a robot arm to a tool that is suspended by an ergonomic arm capable of supporting 3D motion of the tool within a working volume. The apparatus includes a tool sleeve configured to accept the tool, a freely rotating rotary fitting coupled to the tool sleeve, and a coupling that couples a distal end of the robot arm to the rotary fitting. When the tool is inserted into the tool sleeve, the tool is free to rotate around the rotational axis with respect to the robot arm, such that a motion of the distal end of the robot arm does not impose a torque between the robot arm and the tool around the rotational axis, and such that motion of the distal end of the robot arm repositions or reorients the tool within at least a portion of the working volume.

This machine tool has: a main shaft having a tool mounted on the tip thereof; a main shaft head that rotatably supports the main shaft; orthogonal triaxial linear feed shafts that move the main shaft and a table relative to one another; and a rotational feed shaft that is capable of changing the orientation of the rotational axis of the main shaft. The machine tool is provided with: a rotational feed shaft device that is not parallel to any of the linear feed shafts and that rotates the main shaft head around an inclined axis that intersects the rotational axis of the main shaft; and a main shaft head base that rotatably supports the main shaft head so that the point of intersection between the rotational axis and the inclined axis of the main shaft coincides with a defined reference point at the tip side of the main shaft.
