Magnetic coupling devices are disclosed having magnetic field sensors. The magnetic coupling device may include degaussing coils wrapped about pole extension shoes of the magnetic coupling device.

A handle is coupled to an industrial machine tool, along with a method of operating the industrial machine tool via the handle. The handle comprises a housing, a first switch, and a second switch. The housing includes a first side, a second side, a top end, and a bottom end, the first side facing toward the industrial machine tool and the second side facing away from the industrial machine tool. The first switch actuates a float mode for the industrial machine tool, the float mode being a mode in which movement of a moveable portion of the industrial machine tool is power assisted for an operator of the industrial machine tool. The second switch actuates a machining portion, coupled to the moveable portion of the industrial machine tool, to perform a machining process on a workpiece.

This device is provided with: a main shaft (20) onto which a tool (100) is detachably mounted; a rod (30) slidably supported by the main shaft (20) and configured to attach or detach the tool (100) to or from the main shaft (20) through a sliding action; a fluid channel (32) formed in the rod (30); fluid feed device (51, 70) configured to feed a fluid into the fluid channel (32); a plurality of fluid channels for seating detection (24) for detecting when the main shaft (20) and the tool (100) are in a seated state, the fluid channels for seating detection (24) being formed in the main shaft (20) so as to communicate with the fluid channel (32) when the rod (30) is positioned at a first position; and a plurality of fluid channels for cleaning (25) for cleaning seating portions of the main shaft (20) and the tool (100), the fluid channel for cleaning (25) being formed in the main shaft (20) so as to communicate with the fluid channel (32) when the rod (30) is positioned at a second position different from the first position.

Magnetic coupling devices are disclosed having magnetic field sensors. The magnetic coupling device may include degaussing coils wrapped about pole extension shoes of the magnetic coupling device.

The invention relates to a clamping chuck for clamping pallets furnished with a clamping spigot. The clamping chuck has a locating opening for the clamping spigot and a clamping device for clamping the clamping spigot in the locating opening. A plurality of sensors are arranged on the clamping chuck, by means of which the clamping force actions on the clamping spigot may be determined as well as other values. The clamping chuck is equipped with a transmitter for wireless transmission of parameters detected by means of the one or more sensors.

Provided is an ultrasonic displacement sensor that more accurately identifies a plurality of models on a conveyance line on which a plurality of types of workpieces having different specifications coexists, in particular, on a conveyance line of cylinder blocks in a manufacturing facility of engines for automobiles, to thereby improve reliability. An ultrasonic displacement sensor 1 or 2 for transmitting ultrasonic waves to an object, receiving reflected waves, and measuring time between transmission and reception includes: a main body case 41 including an ultrasonic element 31 or 32 at an end; a transparent case 42 attached to the main body case 41; a photoreflector 44 provided at a position of the transparent case 42 and including a light emission portion and a light reception portion; and a switching unit configured to switch, on the basis of output from the photoreflector 44, between an installation mode in which an attachment position of the main body case 41 is adjusted and a measurement mode in which the object is measured.

A workpiece is conveyed from a first fixed point to a second fixed point by a conveyor in a chucked state. A phase of the workpiece that is being conveyed by the conveyor is detected by a detector. The workpiece conveyed to the second fixed point by the conveyor is seated on a seating part. A workpiece seating phase of the seating part is adjusted by an adjustor to the phase of the workpiece detected by the detector.

A machine integrated positioning system shows an operator where to place a raw part in the press brake or other machinery. Further, the operator is informed if the dimensions associated with the raw part are, or are not, correct to produce the planned finished part. The operator is visually shown how the raw part is to be oriented. The operator is informed if the raw part is right-side-up, along with other pre-final placement information. If these and other conditions are not met, the machine integrated positioning system may prevent the press brake and other machinery from cycling.

An automatic positioning and clamping tool for mounting in a CNC Tilting Rotary Table for positioning and clamping a wheel rim for processing by a cutting tool includes a base, an upright post mounted at the base, air leakage detection units mounted on the base for supporting the wheel rim and detecting an air leakage, clamping devices mounted on the base for clamping the border edge of the wheel rim, a lateral chip conveyor, nozzles mounted around the periphery of the lateral chip conveyor, a vertical hydraulic chuck mounted around the upright post for moving a positioning gripper into abutment against the bore wall of the center bore of the wheel rim, and fluid nozzles mounted in the vertical hydraulic chuck for flushing away chips during processing. Thus, the invention is a compact structure with functions of air leakage detection, wheel rim automatic positioning and clamping and chip removal.
