Provided is a workpiece holding tool changing system configured to change at least one of a relative position and a posture of a holding tool of a workpiece conveying apparatus with respect to a feed bar. The feed bar includes at least one set among: an X-axis direction linear mechanism with an X-axis linear brake; a Y-axis direction linear mechanism with a Y-axis linear brake; a Z-axis direction linear mechanism with a Z-axis linear brake; and a ball joint portion and a ball brake. Under a state in which inhibition of movement or change in posture by a corresponding brake is canceled, a robot changes the relative position or the posture of the holding tool to a desired relative position or a desired posture. After the change, the workpiece holding tool changing system is brought into a holding state in which the movement or the change in posture is inhibited.

An adjustable workpiece support system includes an adjustable support apparatus, an analysis support point module, a coordinate post-processing module and a control module. The adjustable support apparatus has a group of support devices for supporting a supported workpiece, the each support device being adjustable in height and angle. The analysis support point module is used to import a computer-aided design file of the supported workpiece, and analyze the computer-aided design file to obtain a group of support points of the supported workpiece. The coordinate post-processing module is configured to calculate the support coordinates of the each support device corresponding to the group of support points. The control module is configured to receive the support coordinates of the each support device, and adjust the height and angle of the each support device to support the supported workpiece, so that the amount of deformation of the supported workpiece is the minimum.

The invention relates to a guide sleeve for a machine tool for the automated placement of stripping claws, wherein a receiving slot (2) is provided at one end and a solid material base (4) is provided at the other end, and wherein a machine-tool stop (3) is positioned between the receiving slot (2) and the solid material base (4). The guide sleeve is characterised in that the receiving slot (2) is an elongate hole.

An electrical tool including: a cutter bit assembly, a driving mechanism for providing a power to the cutter bit assembly, and a flexible transmission mechanism, which is connected at one end thereof to the driving mechanism and connected at the other end thereof to the cutter bit assembly; the flexible transmission mechanism is twistable and bendable, and is configured to transmit the power provided by the driving mechanism to the cutter bit assembly.

A tooling base that is an improvement over current designs in the form of simplified number of parts, easier manufacturing of parts and that can be actuated for clamping and releasing a tooling fixture by pneumatic, other computer controlled means as well as manually is described. The tooling base uses clamping fixtures that are spring loaded to press cleats into recesses on alignment studs that locate and hold any variety of tooling fixtures to the base.

To provide a controller, a data generation device, a control method, and a control program allowing a part of a machining program to be changed easily. A controller comprises: a storage unit that stores change designation data describing a command value in association with respective identifiers indicating at least one block among multiple blocks constituting a machining program for a machine tool; a change unit that reads the multiple blocks in the machining program sequentially, and changes the block indicated by the identifier based on the command value described in the change designation data; and an analysis unit that analyzes the block changed by the change unit, and generates execution data.

A pushing structure of a clamping mechanism is disclosed which comprises a working platform and a chuck. The working platform has a clamping shaft inserted in the chuck, and the chuck has a piston seat and a movable seat at a center of the piston seat for an insertion of the clamping shaft. The chuck further comprises a base at a bottom of the piston seat corresponding to the movable seat and a projection at a bottom of the base. The projection provides an upward push force to the working platform when the piston seat is lifted to release the clamping shaft of the working platform.

A power and signal transmission device for a spindle of a machine tool is provided. The power and signal transmission device includes a spindle fixing portion, a shaft rotating portion, a power transmission component and a signal transmission component. The spindle fixing portion is provided with a power input end, a primary side power induction coil, a secondary side signal induction coil and at least one signal output end. The shaft rotating portion is provided with a joining end surface for bonding to a holder, a secondary side power induction coil and a primary side signal induction coil, and is rotatable with respect to the spindle fixing portion. The power transmission component transmits an electrical energy from the power input end. The signal transmission component transmits a holder signal to the signal output end. Each of the power and signal transmission components includes at least one elastic pogo pin.

The invention relates to a clamping bushing (21) for clamping in a bore (3) of a component (2), in particular of a workpiece to be clamped, wherein the clamping bushing (21) is radially contracted in a relaxed state such that the clamping bushing (21) can be inserted into the bore (3) and pulled out of the bore (3), whereas the clamping bushing (21) is radially expanded in a stressed state such that the lateral surface of the clamping bushing (21) forms a mechanical connection to the inner wall of the bore (3). According to the invention, the mechanical connection between the lateral surface of the clamping bushing (21) and the inner wall of the bore (3) is positive-locking and consists of a threaded connection. The invention further relates to a corresponding clamping device (1). An essential feature of the invention is also the possibility of being able to exchange the clamping bolt (tension anchor) by means of a bayonet coupling without having to open hydraulic lines and without removing the clamping element from the device.

A rotary union includes a housing forming a bore and a piston bore having an open end and disposed at a radially offset distance with respect to the bore. The piston bore is fluidly isolated from the bore. A seal carrier is slidably disposed within the bore, and includes an actuation arm extending radially outwardly relative to the bore such that it overlaps the piston bore. A piston slidably disposed in the piston bore is extendible to releasably abut the actuation arm and urge the seal carrier to displace relative to the bore when the piston displaces relative to the piston bore.
