A folding device for a milling machine includes a base having a workbench formed on top thereof, and two support parts are respectively located on two sides of the workbench so as to be connected to two support boards respectively. A pivot and a fixing bolt extend through the contact face and are fixed to the support part. A driving unit includes a transverse rail and a transverse shaft respectively connected between the two support boards. A slide is slidably connected with the transverse rail and the transverse shaft. A milling machine is connected to the slide which is movable between the two support boards. When the fixing bolts are removed, the milling machine is foldable toward the workbench about the two respective pivots to save transportation space and storage space required.

An elliptical ultrasonic machining device powered by non-contact induction mainly includes an induction power supply device and an elliptical ultrasonic spindle shank, wherein: induction power supply secondary units of the induction power supply device encircle a spindle shank shell of the elliptical ultrasonic spindle shank; induction power supply primary units are arranged at a primary magnetic core seat outside the elliptical ultrasonic spindle shank; the primary magnetic core seat and the elliptical ultrasonic spindle shank have a same circle center, and a small gap exists between the primary magnetic core seat and the elliptical ultrasonic spindle shank; the primary magnetic core seat is fastened on a machine tool spindle seat of a machine tool through a support and keeps still; the elliptical ultrasonic spindle shank is mounted on a machine tool spindle through a taper shank and rotates with the spindle in a high speed.

A compliance unit includes a return piston that causes a first body and a second body to return to a home position and a locking mechanism that locks the return piston in the home position. The locking mechanism includes a locking member that is capable of being freely displaced to a locking position where the locking member is fixed in place by being in contact with the return piston and to a non-locking position where the locking member is not in contact with the return piston and is not fixed in place, a locking spring that presses the locking member toward the locking position, an unlocking piston that presses the locking member toward the non-locking position, an unlocking pressure chamber that causes the unlocking piston to generate thrust, and an unlocking port for supplying air to the unlocking pressure chamber.

A vacuuming-off device includes at least one vacuuming-off unit that has at least one interface. The interface is mechanically and electrically connectable to a hand-held power tool, in particular to a hammer drill and/or chipping hammer, in at least one first application. The vacuuming-off device further includes an adapter unit that, in at least one second application, is connectable to the interface. The adapter unit has at least one connecting unit that is connectable to at least one energy supply.

A machine apparatus that a user can more easily operate includes a machine driver that is mechanically driven, a main operation unit that operates the machine driver, a remote operation unit that transmits an operation instruction signal to the machine driver at a position apart from the main operation unit, a position determiner that determines a position of the remote operation unit, and a controller that, upon determining that the remote operation unit is located in a predetermined area, enables operations by the main operation unit, and upon determining that the remote operation unit is located outside the predetermined area, disables at least some operations by the main operation unit.

Embodiments of the disclosure provide a tool and method for alignment adjustment of machinery. The tool may include a bottom plate, a top plate oriented in parallel planes, a low friction intermediate element between bottom plate and top plate, and a hydraulic actuator or electro-mechanic actuator arranged between the bottom plate and the top plate and capable of moving the top plate relative to the bottom plate.

A technological equipment for tank track moving supports is provided and includes a zero-point positioning system, a workpiece identifying system and a clamping apparatus in cooperation with the moving support, the clamping apparatus includes a tooling plate, a clamp and a pressing device for pressing the moving support are detachably connected to the tooling plate, the moving support is located between the clamp and the pressing device, and the pressing device abuts against the moving support. The moving support with different shapes and sizes can be clamped, and the clamping is stable and convenient to operate.

A leveling adjustment device attached to a machine tool with supporting foot portions being adjusted manually to change a height, which includes a sensing module and a microcontroller unit. The sensing module senses the machine tool for inclined extents in two directions perpendicular to each other and then generates a sensed data. The microcontroller unit receives the sensed data and provides a graphical operation interface with first blanks and second blanks. The first blanks are used to fill with a length and width data of the machine tool while the second blanks are used to fill with a coordinate data corresponding to each of the supporting foot portions. The microcontroller unit calculates an adjustment sequence and an adjustment value corresponding to each of the supporting foot portions based on the data in the first and second blanks in conjunction with the sensed data and then displays in the graphical operation interface.
