A work table apparatus is disclosed for supporting a ferromagnetic object, the work table apparatus including a table having a first side and a second side opposite the first side, the first side oriented to support the ferromagnetic object. A magnetic assembly can be positioned adjacent the second side of the table, the magnetic assembly configured to produce a magnetic field extending exterior to the magnetic assembly to secure a ferromagnetic object in a desired position on the table. The magnetic assembly can be configured to alternate between an active mode where the magnetic field is produced and an inactive mode wherein magnetic fields produced by the magnetic assembly are retained within the magnetic assembly.

A rail processing device (1) comprising at least a first (3A) and a second work station (3B) provided on a common frame (30), and configured to alternately lock a rail (2) when the latter is being processed, each work station (3A, 3B) comprising at least a first magnetic anchorage plane (4) configured to cooperate with a web (2A) of the rail (2) when the latter is being processed in the respective station, and a transport system (50A, 50B) to move the rail (2) from the first work station (3A) to the second work station (3B) and vice versa.

An adjustable depth magnetic device comprises a switchable magnet, switchable magnet carrier, or switchable magnet integrated into a carrier, constrained by and locked into position by a receiver that is separate from or integrated into an object or fixture. The adjustable depth magnetic device may be affixed to or integrated into an object for the purpose of constraining said object to a ferrous target; or the adjustable depth magnetic device may be affixed to or integrated into a fixture to facilitate manufacturing, production, and/or assembly operations.

A system for manufacturing an assembly board includes an undersupporting device, a transporter configured to transport a board and the undersupporting device, an undersupporting-device installer provided below the transporter, the undersupporting-device installer being attachable to and detachable from the undersupporting device, a board processor configured to perform a predetermined processing to an upper surface of the board, a carry-in side delivering unit having first and second receiving positions different from each other, a board supplier configured to supply the board to the first receiving position, and an undersupporting-device supplier configured to supply the undersupporting device to the second receiving position. The transporter transports, to the carry-in side delivering unit, the undersupporting device detached from the undersupporting-device installer. The carry-in side delivering unit positions, at the second receiving position, the undersupporting device delivered from the transporter to allow the undersupporting device to be carried out from the second receiving position.

A system for manufacturing an assembly board includes an undersupporting device, a carrier configured to hold the undersupporting device, a transporter, an undersupporting-device installer attachable to and detachable from the undersupporting device, a board processor, and a magnet provided on a lower surface of the undersupporting device. The transporter transports the undersupporting device to a working position by transporting the carrier to the working position while the carrier holds the undersupporting device on the lower surface of the carrier. The transported undersupporting device is fixed to the undersupporting-device installer by a magnetic force of the magnet at the working position. The transporter transports the board to the working position. The undersupporting device supports the lower surface of the board when the board is transported to the working position. The board processor performs a predetermined processing to an upper surface of the board.

A method of milling a piece of raw steel stock comprising: presenting a piece of raw steel stock having a first surface and a second surface having a perimeter; presenting a magnetic chuck with a top surface configured to support the piece of raw steel stock for milling with magnetic capabilities; arranging a minimum of four solid pole extensions on the top surface to support the second surface of the piece of raw steel stock for milling of the first surface thereof such that the solid pole extensions will be relatively evenly distributed beneath the perimeter of the second surface; arranging multiple mobile pole extensions on the top surface to further support the second surface; placing the second surface onto the multiple mobile pole extensions and the solid pole extensions; activating the magnetic capabilities of the magnetic chuck; and milling the first surface to a desired flatness.

System for manufacturing an assembly board includes an undersupporting device, a transporter, an undersupporting-device installer attachable to and detachable from the undersupporting device, a board processor, a carry-in side delivering unit having different first and second receiving positions, a board supplier configured to supply the board to the first receiving position, and an undersupporting-device supplier configured to supply the undersupporting device to the second receiving position. The carry-in side delivering unit delivers the undersupporting device to the transporter, which transports the undersupporting device to a working position. The undersupporting-device is fixed to the undersupporting-device installer. The carry-in side delivering unit delivers the board to the transporter, which transports the board to the working position.

A fixing device for a secondary battery test having a seating stage on which the secondary battery to be tested is seated and which is provided as a magnetic body, a cover provided as a magnetic body to cover the secondary battery, and a magnetic force generator providing magnetic force to the seating stage and the cover is provided. When the magnetic force is transmitted from the magnetic force generator to the seating stage and the cover, attractive magnetic force is generated between the cover and the seating stage to fix the secondary battery disposed between the cover and the seating stage without moving.

A jig has a frame, a carrier and a hood latch supporting assembly. The frame has two first shafts and a bracket attachment portion. The carrier has two sliders and a second shaft. The two sliders are fitted to the first shafts for movement in a Z-direction along the first shafts. The second shaft is perpendicular to the first shafts. The two sliders and the second shaft are rigidly fixed to one another. The hood latch supporting assembly has a second slider and a latch support portion. The second slider is fitted to the second shaft for movement in an X-axis direction along the second shaft. The latch support portion is coupled to the second slider for movement therewith. The frame assembly allows movement of a latch mechanism loosely fitted to a bracket during alignment of the latch mechanism to the bracket.

A method is provided for positioning a component, in particular a sheet metal component, which has a first hole or a first recess. The component with the first hole or the first recess is placed on a first support which is spherical-shaped or shaped as a spherical cap.
