The magnet cutting device includes a pair of supporting portions spaced apart by a predetermined distance and configured to support the magnet from a bottom side, a blade configured to press the magnet supported by the pair of supporting portions from an upper side of the magnet, and a magnet supporting tool arranged between the pair of supporting portions to support the magnet from the bottom side of the magnet. A surface of the magnet supporting tool to be held in contact with the magnet is shaped such that a central part of an upper end is higher than the upper ends of the pair of supporting portions and an end part of the upper end is lower than the upper ends of the pair of supporting portions when the magnet is placed on the surface, the upper end having a slope connecting the central part and the end part.

Magnet cutting device

A field-pole magnet manufacturing apparatus fractures a magnet fixed on a die serving as a lower tool by causing a punch of an upper tool to press the magnet while in contact with the magnet. At least one projection is formed in the punch of the upper tool symmetrically with respect to the central position of the magnet in the width direction of the magnet.

Apparatus and method for manufacturing field-pole magnet

A manufacture method that includes positioning the permanent magnet body of which a surface is coated with a coating film for deterioration prevention, a scheduled cleavage portion of the permanent magnet body being located between two fulcrums, which are edge portions of a die, supporting the permanent magnet body, and cleaving the permanent magnet body into a cleaved magnet body and the magnet piece by pressing the scheduled cleavage portion of the permanent magnet body is provided. The manufacture method also includes cutting the coating-film between the cleaved magnet body and the magnet piece by pressing an end portion of the cleaved magnet piece from a pressing side of the scheduled cleavage portion, the end portion being on a side opposite to a cleavage surface side.

A magnet insertion method into a rotor core is to insert an assembly into a magnet insertion hole provided in the rotor core of an electric motor, the assembly being formed by laminating a plurality of members, including at least a plurality of magnet pieces, in a line. According to this magnet insertion method, the assembly is formed by arranging a front member, having a surface surrounded by a chamfered ridge line, to cause the surface to be a front side end surface upon insertion, by laminating, on its rear side in an insertion direction, other members, without having the chamfered ridge line, in a line along the insertion direction to cause the other members to be hidden inside a projection of the front member when being projected from an insertion hole side, and by temporarily holding the front member and the other members.

Magnet insertion method into rotor core

A magnet inserting apparatus into magnet insertion slots of a rotor core is configured to arrange a guide tape (a belt-shaped member) along an inner wall surface of the magnet insertion slot, and the guide tape having a coefficient of friction smaller than that of the inner wall surface of the magnet insertion slot. The magnet inserting apparatus is configured to insert the magnet parts into the magnet insertion slot, the guide tape (the belt-shaped member) being arranged on the inner wall surface of the magnet insertion slot.

A field-pole magnet manufacturing apparatus manufactures magnet pieces that constitute a field-pole magnet arranged in a rotary electric machine by fracturing the magnet. This manufacturing apparatus includes: a support unit on which the magnet is placed; a fracture unit that is arranged opposite to the support unit across the magnet and is configured to fracture the magnet by pressing the magnet while in contact with the magnet; and a powder removal unit that is configured to remove crush powder produced by fracture of the magnet.

A manufacturing device for cleft magnets comprises a cleaving mechanism for cleaving a magnet plate by applying a pressing force to the magnet plate corresponding to a back of a groove formed on one surface of the magnet plate and a carry-in mechanism for carrying the magnet plate to a cleaving position by the cleaving mechanism. By comprising a foreign matter removal mechanism for removing a foreign matter adhering to the magnet plate before the magnet plate is carried to the cleaving position by the carry-in mechanism, the foreign matter adhering to the magnet plate is removed before cleaving.

A magnet inserting apparatus inserts a plurality of magnet parts into each of the magnet insertion slots provided in the rotor core of a motor. The magnet inserting apparatus comprises a guiding unit equipped with a magnet inlet and a magnet outlet and is configured to align the plurality of magnet parts inserted through the magnet inlet until the inserted magnet parts are ejected from the magnet outlet, and to guide the aligned magnet parts so as to be inserted from the magnet outlet to the magnet insertion slot. A size of the magnet inlet of the guiding unit is larger than a size of the magnet insertion slot, a size of the magnet outlet is the same as or smaller than the size of the magnet insertion slot, and the guiding unit is formed so that a shape from the magnet inlet to the outlet becomes a taper shape.

A magnet evaluating device evaluates an evaluation magnet by passing the evaluation magnet, which is formed by connecting a plurality of magnetic sections with insulating material in between, and a master magnet of the same form through an alternating magnetic field generated by an excitation coil, measuring the eddy current occurring in the magnetic section as voltage or current occurring in a detection coil and comparing the measured value for the evaluation magnet and the measured value for the master magnet.

Magnet evaluating device and method

A boring cutter body () is inserted into a circular hole () and is rotated and moved in an axial direction, whereby screw-shaped groove parts () are formed by using a tool bit () provided on a tip end of an outer peripheral portion, and broken surfaces () are formed by breaking tips of ridge parts generated by formation of the groove parts (). Moreover, the groove parts () are processed through electric discharge machining using a wire electrode () provided to the boring cutter body () behind the tool bit () in the rotating direction, thereby forming finely roughened portions () having more finely roughened shapes than the broken surfaces ().

Prespray processing method

A cylindrical internal surface processing method comprises forming a cylinder bore, roughening an upper section of the bore, depositing coating onto the bore, and machining a lower section of the bore and the coating. The forming of the cylinder bore includes forming the upper and lower sections with the lower section being axially spaced from the upper section and having an axial length greater than zero. The roughening creates a roughened surface such that a radially innermost edge of the roughened surface has an internal diameter smaller than an internal diameter of the lower section. The coating is deposited to cover the upper section and at least a portion of the lower section. The machining forms a tapered portion and a cylindrical portion, a radially outermost edge of the cylindrical portion having an internal diameter larger than that of a radially outermost edge of the roughened surface.

An apparatus and method for surface finishing a workpiece is disclosed as including a workpiece supporting mechanism supporting a workpiece having a target shaped periphery with a given width to be surface finished and a tool holder holding a surface finish tool in abutting contact with the target shaped periphery of the workpiece. A pressure applying mechanism is operative to apply a pressure force to the surface finish tool through the tool holder to cause the surface finish tool to be held in pressured contact with the target shaped periphery, with the pressure force exhibiting a given distribution pattern depending upon an axial direction of the workpiece. A drive mechanism rotates the workpiece to allow the surface finish tool to surface finish the target shaped periphery into a given geometrical profile, variably contoured along an axis of the workpiece depending on the given pressure distribution pattern.
