Block stator press-fitting shell device

Abstract

The invention discloses a block stator press-fitting shell device. The device comprises a banding ring, an upper template, a middle template, a lower template, guide columns, guide sleeves, an upper pressure head, a lower pressure head, a limiting block, a bolt and a nut, wherein guide sleeve holes are formed in the upper template, the middle template and the lower template; the guide sleeves arearranged in the guide sleeve holes; the guide columns can slide up and down on the guide sleeves; a positioning hole is formed in the middle of the middle template; the upper pressure head extends upwards from the inside of the positioning hole of the middle template; the bottom of the upper pressure head is fixedly connected with the middle template; the bottom of the lower pressure head is fixedly connected with the middle of the lower template; the limiting block is connected with the lower template; a stop hole groove of the upper pressure head is used for placing a shell; and a stop holegroove of the lower pressure head is used for placing a stator sleeved with the banding ring. According to the device, the roundness requirements of the stator can be met; the magnitude of interference of the assembled stator and shell can be guaranteed, so that the assembling quality of the motor is high; for different products, only the upper pressure head and the lower pressure head need to bereplaced, so that the different products can be used on the same device; and the operation is simple, the production efficiency is high, and batch production is facilitated.

Description

technical field [0001] The invention relates to the technical field of motor assembly, in particular to a device for press-fitting a segmented stator into a housing, in particular to a press-fitting device for pressing a segmented stator into a housing. Background technique [0002] With the rapid development of the motor industry, limited by the installation space of the equipment, the external dimensions of the motor are required to be smaller and smaller under the condition of constant input torque. In the automatic production of embedded wires, most of the existing stators are segmented and spliced. However, this increases the difficulty of motor installation. How to automatically and universally press-fit the segmented stators to the housing is one of the key points of the motor assembly process. . [0003] In the prior art, some stators are spliced, that is, each stator core block is equipped with an insulating frame and windings are wound on the insulating frame to f...

AI Technical Summary

Problems solved by technology

The disadvantage of this assembly process is that the inner roundness of the stator after pressing is not ideal, and the motor with a large motor torque requires a large interference between the stator and the housing, which is likely to cause uneven interference, and the assembly quality of the motor is poor. , for each type of motor and its derivatives, it is necessary to make a press-down tooling separately, which is poor in versatility
