Abstract
The invention discloses a mini motor assembly fixture and an assembly method. The mini motor assembly fixture comprises a base and a mounting column arranged on the base, wherein the upper end of the mounting column is a casing positioning end at which a motor casing is sleeved; a central hole is formed in the center of the upper end of the mounting column, through which a motor central shaft passes; the fixture further comprises a positioning sleeve sleeved outside the mounting column and an ejector movably inserted in the positioning sleeve; the inner wall of the positioning sleeve is in sliding contact with the outer wall of the motor casing; the height of the positioning sleeve is higher than that of the mounting column; and the ejector, the inner bore of the positioning sleeve, the casing positioning end and the central hole are all coaxial. The fixture disclosed by the invention has a simple structure and is convenient to use; and the method using the fixture can be used for completing the assembly operation more rapidly, ensuring the product assembly quality more stable and greatly reducing the rejection rate of products. The motor casing and the motor central shaft are protected against deformation during assembly and keep firm and stable after assembly. The concentricity and coaxiality are improved, and the performances in all aspects can satisfy the design requirements.

Wherein, the lower end that described thimble contacts with motor axis is provided with one for preventing that motor axis is out of shape, is interspersed in the top of motor axis when being pressed into motor case.
In addition, another technical problem that the present invention will solve is to provide a kind of mini motor casing and motor axis assemble method, and the method can guarantee motor case and the rear firm stable of motor axis assembling, reaches product design requirement.
Thus, the present invention adopts following scheme to realize:
A kind of mini motor casing and motor axis assemble method, this assembling adopts special-purpose assembled fixture, this tool comprises a base, on base, be provided with an erection column, erection column upper end is the shell positioning end of sheathed motor case, center, erection column upper end is provided with the centre bore of interspersed motor axis, this tool also comprises that positioning sleeve and the activity being placed on outside erection column is interspersed in the thimble in positioning sleeve, positioning sleeve inwall and the sliding contact of motor case outer wall, positioning sleeve height is higher than erection column height, the lower end that thimble contacts with motor axis is provided with one for preventing that motor axis is out of shape when being pressed into motor case, be interspersed in top in motor axis, thimble, positioning sleeve endoporus, the equal concentric of shell positioning end and centre bore, the method comprises the steps:
A, motor case is placed on to shell positioning end, then motor axis is interspersed in motor case,
B, positioning sleeve is placed on motor case and erection column,
C, thimble is interted in positioning sleeve, and make top extending in motor axis upper end downwards, then press down thimble motor axis upper end is entered in motor case completely, complete the assembling of motor case and motor axis.
The jig structure that the present invention discloses is succinct, easy to use, it is quicker that the method for combination can make assembling work with it, product assembly quality is more stable, can greatly reduce the fraction defective of product, when assembling, can guarantee that motor case and motor axis can not be out of shape, firm stable after assembling, concentricity and axiality are high, and various aspects of performance all can meet design requirement.
