Description

Integral permanent magnet ring embedding self-location permanent magnet structure

Technical field

The present invention relates to electric information, particularly a kind of integral permanent magnet ring embedding self-location permanent magnet structure.

Background technology

In current powered appliance industry, the technical scheme that permanent-magnet structure designs and produces mainly contains two kinds.A kind ofly be: at first with multi-disc permanent magnetism lobe one by one adhesive then inner yoke is sleeved on permanent magnetism lobe inboard to outer yoke locating surface place, use adhesive with outer yoke, permanent magnetism lobe, bonding back and the moving magnetic channel that forms unshakable in one's determination of being integral of inner yoke at last; Another kind is: at first multi-disc permanent magnetism lobe is pull-in on the seating surface of outer yoke one by one, inner yoke is designed to have the shoulder structure of locating surface then, and it is sleeved on the inboard of permanent magnetism lobe, utilize the locking positioning device permanent magnetism lobe to be positioned on the outer yoke at last, form after the one and the moving magnetic channel that forms unshakable in one's determination together with inner yoke.

Though all there are some defectives in the technical scheme comparative maturity of two kinds of methods:

1, part processing dimensional requirement precision height, difficulty of processing is big;

2, quality of fit height between parts, assembly difficulty is big, and product percent of pass is low;

3,, and in the working region, be unfavorable for using erecting tools because the magnetic force that produces between permanent magnetism lobe and yoke is very big, very inconvenient when causing the assembling parts, but also easily human body is caused the extruding injury;

4, the productivity ratio of product is lower, is unfavorable for big production and the streamlined operation in enormous quantities.

Summary of the invention

The object of the present invention is to provide a kind of integral permanent magnet ring embedding self-location permanent magnet structure, solve existing permanent-magnet structure part processing dimensional requirement precision height, difficulty of processing is big and parts between the quality of fit height, assembly difficulty is big even cause human injury's problem.

Technical scheme of the present invention: integral permanent magnet ring embedding self-location permanent magnet structure is made up of last cap, loam cake, inner yoke, integrated permanent-magnet body, outer yoke, coil, lower cover and output shaft;

Wherein, outer yoke is a housing structure, the integrated permanent-magnet ring is embedded in the housing structure of outer yoke, inner yoke is fixedlyed connected with output shaft and is integral, and be loaded in the housing structure of outer yoke with corresponding integrated permanent-magnet ring among, coil is loaded on the bottom of the integrated permanent-magnet ring between outer yoke and the inner yoke, and loam cake and lower cover are installed on the upper and lower part of outer yoke respectively, and last cap is loaded on and covers;

The integrated permanent-magnet ring is made up of permanent-magnetic clamp outer ring, permanent magnet, permanent-magnetic clamp inner ring, permanent magnet is assemblied between permanent-magnetic clamp inner ring and permanent-magnetic clamp outer ring, by the fit structure and the magneticaction of part itself, make permanent-magnetic clamp outer ring, permanent magnet, permanent-magnetic clamp inner ring form holistic permanent-magnetic clamp structure;

Wherein, permanent magnet is made of at least one permanent magnetism lobe or a plurality of permanent magnetism lobe.

The installation method of integral permanent magnet ring embedding self-location permanent magnet structure:

1, the making of integrated permanent-magnet ring and installation are that a permanent magnetism lobe or a plurality of permanent magnetism lobe are assemblied between permanent-magnetic clamp inner ring and permanent-magnetic clamp outer ring, and the structure by magnetic force and part itself forms an integral unit with permanent-magnetic clamp outer ring, permanent magnet, permanent-magnetic clamp inner ring.

2, with professional anchor clamps the integrated permanent-magnet ring is assembled to and carries out location just in the outer yoke, relend and help external force to promote the integrated permanent-magnet ring to the service position by inner yoke, whole process does not need the measurer of accurate positioner and specialty, be to rely on this body structure of parts and dimensional accuracy to adjust the location fully, and realize that zero-air-gap contacts entirely.

The invention has the advantages that:

1, complete machine processing, assembly difficulty are reduced, reduced cost.

2, improve installation accuracy, guaranteed the qualification rate of product, can reach 100%.

3, the position can be adjusted automatically between parts, and contact-making surface can realize that zero-air-gap contacts entirely between integrated permanent-magnet ring and outer yoke, inner yoke, will hang down the magnetoimpedance passage and reach optimization, makes product keep the magnetic force maximization, and can guarantee its reliability steady in a long-term.

4, special use in the assembling process, easy to use, simple, quick, accurate, the safety of general utility tool.

5, processing, assembly technology are simplified, and are fit to produce in enormous quantities and the streamlined operation.
