Inner flat curved copper strip embedded tooling of motor sealing ring and embedding method

Abstract

The invention discloses an inner flat curved copper strip embedded tooling of a motor sealing ring and an embedding method, and solves the problems of poor assembly stability and low positioning precision when a thin copper strip is embedded on the inner side surface of a mother half ring. The steel mother half ring (9) is abutted on the inner curved surface of a curved positioning strip (6), a swing rod (5) is hinged on a center pin shaft (4), a bearing (13) is arranged on one end of the swing rod (8), the bearing is provided with a rotating shaft (16), a roller (14) is fixedly connected withthe lower end of the rotating shaft (16), the wheel surface of the roller abuts the inner circular side of the curved positioning strip (6), a roller annular groove (15) with a U-shaped opening is formed in the wheel surface of the roller, the roller annular groove and the steel mother annular groove (10) are disposed on the same horizontal surface, and a curved flat copper strip is disposed between the steel mother annular groove (10) the roller annular groove (15). The tooling has high pass rate and low processing cost.

Description

Technical field [0001] The invention relates to a manufacturing tool for a motor sealing ring, in particular to an embedding tool and an embedding method in which a flat arc-shaped copper strip is embedded on the inner surface of the motor sealing ring. Background technique [0002] The seal ring of the DC propulsion motor is connected in series between the end cover of the motor base and the shaft. The seal ring acts as an oil seal and eliminates static electricity; the forming process of the seal ring is to embed a semi-annular flat copper strip into two In the 2 mm wide annular sealing groove in the half ring of the steel mother body, then, the bolts on the steel mother body joining block are connected to form a sealing ring. The assembly of the steel mother half ring and the half ring flat copper strip is a cold assembly transition fit. Because the half ring flat copper strip is thin and elastic, when the half ring flat copper strip is inserted into the shallow annular groove...
