A manufacturing method for a rotary electric machine is equipped with an insertion roller having an outer circumferential surface configured to contact a coil lead line in such a manner that the coil lead line is inserted into accommodating grooves of an insulator, a roller support section that rotatably supports the insertion roller, and a bending unit that performs a bending process to bend the coil lead line by coming into contact with the coil lead line so as to form a terminal part.

Device for manufacturing a rotary electric machine

A manufacturing apparatus, of a grinding stone which is manufactured by attaching abrasive grains respectively having polyhedral shapes in which mutually opposed surfaces are parallel to each other to a base member, is provided with: an abrasive grains classifying apparatus adapted to classify the abrasive grains based on sizes of the abrasive grains defined by face-to-face distances between the mutually opposed surfaces; and an attaching apparatus adapted to attach the abrasive grains classified by the abrasive grains classifying apparatus to the base member. The attaching apparatus is provided with: a template which is disposed above the base member to be movable with respect to the base member and formed with a guide hole through which the classified abrasive grains pass; a vibration generator connected to the template or the base member and adapted to apply a vibration to the abrasive grains passing through the template; and an electrolytic deposition bath adapted to electrolytic deposit the abrasive grains passing through the template.

A coil strand is wound on an insulator to produce a divided core member, and then the divided core member is placed on a table. While the table rotates about its axis, ends of the coil strands are inserted into lead end holding grooves, which are defined in a surface of the insulator on an outer circumferential edge of a stator and which extend along a circumferential direction of the stator.

Method of manufacturing rotary electric machine

A rotary electric machine includes a plurality of lead end holding grooves defined in insulators at an outer circumferential surface of a stator core, for guiding respective ends of coil leads therein. The lead end holding grooves are defined by ledges of the insulators. The ledges have respective lands which are convex in widthwise directions of the lead end holding groove.

An armhas a shape for grasping a part in a circumferential direction of a tool holder. The armis connected to the tool holderwith a boltinserted into a fixing holeprovided in a base side portion of the arm. A tapped holeused for exchangeably attaching a cutting toolis formed in a tip side portion of the arm. A groove partextending in parallel to an axis of the tool holderis formed in a position close to the base portion of the arm. Owing to the groove part, the armworks as an elastic hinge when an external force is applied, so as to increase or decrease a radial dimension of the cutting toolwhile keeping its parallelism to the axis of the tool.

Bore working tool

A tool for grinding an inner diameter even when holders having grindstones are axially connected. A gap enclosed by the inner peripheral surface of a divided tool holder, a draw bar and O-rings is formed in a state in which the draw bar is inserted into a tool holder in which a plurality of divided tool holders are connected in series. A filler is filled into the gap to fix a support bush to the divided tool holder. An adjustment screw of each arm held circumferentially away from each other on the divided tool holder is turned to adjust a distance between a pin and the arm, and the radial projecting amount of each of grindstones is adjusted. The projecting amount is adjusted such that the plurality of grindstones rotate along the same rotational trajectory and the center of the rotational trajectory corresponds to the axis of the draw bar.
