Permanent magnet direct current motor elastic piece cutting mechanism and method and elastic piece feeding device

Abstract

The invention discloses a permanent magnet direct current motor elastic piece cutting mechanism which comprises a mounting seat, a guide column, a lifting seat, a roller, a first-stage air cylinder, a second-stage air cylinder, a driving inclined plate, a cutting block and a pressing block, wherein a first sliding groove and a second sliding groove are formed in the mounting seat, the second-stage air cylinder is movably connected into the first sliding groove, the first-stage air cylinder is mounted on the mounting seat; a telescopic end of the first-stage air cylinder is connected with a second-stage air cylinder base, and the driving inclined plate is movably connected into the second sliding groove and connected with a telescopic end of the second-stage air cylinder; the guide column is arranged on the mounting seat, and the lifting seat is movably connected to the guide column through a linear bearing; the roller is rotationally connected to the lower end of the lifting seat and is matched with the upper end surface of the driving inclined plate; the cutting block and the pressing block are both connected to the lifting seat, the cutting block is fixedly connected with the lifting seat, and the pressing block is connected with the lifting seat through a pressed spring. The permanent magnet direct current motor elastic piece cutting mechanism has the advantages of being high in cutting precision and cutting efficiency.

Description

technical field [0001] The invention relates to the field of motor production, in particular to a shrapnel cutting mechanism and method for a permanent magnet DC motor and a shrapnel feeding device. Background technique [0002] Motors are widely used in various portable electronic devices or appliances, such as tape recorders, VCD players, record players, electric massagers and various toys. Permanent magnet DC motors are a kind of DC motors that use permanent magnets to establish a magnetic field. The structure of the permanent magnet DC motor consists of a general stator and a rotor, and the stator includes a casing, magnetic tiles, magnetic tile frames, riveting parts, and the like. In the prior art, the permanent magnet DC motor stator assembly is generally done manually, such as Figure 7 The shown motor rotor consists of a casing (100), a mandrel (200), shrapnel (300) and a rotor (400). The mandrel (200) is fixed on the casing (100), the shrapnel (300) is sleeved on ...
