Description
Technical field
The utility model belongs to a kind of magnetic circuit rule, relates in particular to a kind of magnetic circuit rule that are used for the magnet steel location.
Background technology
In the stereo set assembling process, need a pair of bonding magnetic steel on two sides of anter, and will guarantee that the axial line of a pair of magnet steel and anter coincides.Because this a pair of magnet steel repels each other, in the prior art, after employing is through first magnet steel, anter, second magnet steel on the axle successively usually, be clipped in respectively on first magnet steel and second magnet steel to overcome the magnetic force that repels each other with two clips again.Yet, since the spring force of clip usually a little less than, and can't guarantee that the elasticity of two clips is identical, the concentricity that therefore can't guarantee the axial line of first magnet steel, anter, second magnet steel makes in the magnetic gap Distribution of Magnetic Field even, and efficiency of assembling is lower.Be badly in need of a kind of concentricity of the axial line of first magnet steel, anter, second magnet steel and magnetic circuit rule convenient for assembly can guarantee to assemble the time on the market.
The utility model content
The purpose of this utility model provides a kind of concentricity of the axial line of first magnet steel, anter, second magnet steel and magnetic circuit rule convenient for assembly can guarantee to assemble preferably the time.
The utility model can be implemented by the following technical programs: a kind of magnetic circuit rule, it comprises the magnetic circuit gauge with through hole, the inwall of described through hole has a plurality of steps from top to bottom successively and forms the containing hole that differs in a plurality of continuous apertures, and the axial line of described a plurality of containing holes coincides.
Described containing hole upwards is followed successively by first containing hole that is used to place first magnet steel, second containing hole that is used to place anter by centre bore, and described through hole is followed successively by the 3rd containing hole that is used to place second magnet steel, the 4th containing hole that is used to place the bonding anter and first magnet steel downwards by centre bore.
The aperture of described centre bore, first containing hole, second containing hole increases successively.
The aperture of described centre bore, the 3rd containing hole, the 4th containing hole increases successively.
Connecting portion between described centre bore and the 3rd containing hole is formed for pressing down the pressing down section of second magnet steel.
Compared with the prior art the utility model has following advantage:
Because the containing hole that differed by a plurality of continuous apertures of through hole of the present utility model is formed, and the axial line of a plurality of containing holes coincides, and makes the concentricity of the axial line of first magnet steel, anter, second magnet steel in the time of can guaranteeing to assemble preferably when assembling.Specifically, first magnet steel that at first will scribble glue during assembling is placed in first containing hole, and the anter that scribbles glue is placed in second containing hole, makes win magnet steel and anter bonding.First magnet steel that will be bonding and anter take off and are placed on iron bowl inside then, second magnet steel that scribbles glue is placed on the anter upper surface, fill in slit between iron bowl and the magnet steel with the lower port of magnetic circuit rule, make second magnet steel snugly be positioned at the 3rd containing hole, and being used to of forming between centre bore and the 3rd containing hole pressing down section that presses down second magnet steel firmly second magnet steel is pressed on the upper surface of anter.Compared with prior art, the concentricity of the axial line of first magnet steel, anter, second magnet steel when not only guaranteeing assembling preferably makes that Distribution of Magnetic Field is even in the magnetic gap, and the efficiency of assembling that improved easy to assembly.
Description of drawings
Sectional structure schematic diagram when accompanying drawing 2 is assembling first magnet steel and anter;
Accompanying drawing 3 is the structural representation of assembling second magnet steel on the anter and first magnet steel;
Wherein:
1, through hole; 2, magnetic circuit gauge; 3, step; 4, containing hole; 5, first magnet steel; 6, first containing hole; 7, anter; 8, second containing hole; 9, second magnet steel; 10, the 3rd containing hole; 11, the 4th containing hole; 12, centre bore; 13, pressing down section; 14, iron bowl.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is elaborated:
As shown in accompanying drawing 1 and accompanying drawing 2, a kind of magnetic circuit rule, it comprises the magnetic circuit gauge 2 with through hole 1, and the inwall of described through hole 1 has a plurality of steps 3 from top to bottom successively and forms the containing hole 4 that differs in a plurality of continuous apertures, and the axial line of described a plurality of containing holes 4 coincides.Magnetic circuit gauge 2 is made by the harder plastic material of material usually.
Described containing hole 4 upwards is followed successively by first containing hole 6 that is used to place first magnet steel 5, second containing hole 8 that is used to place anter 7 by centre bore 12, and described through hole 1 is followed successively by the 3rd containing hole 10 that is used to place second magnet steel 9, the 4th containing hole 11 that is used to place the bonding anter 7 and first magnet steel 5 downwards by centre bore 12.
The aperture of described centre bore 12, first containing hole 6, second containing hole 8 increases successively.
The aperture of described centre bore 12, the 3rd containing hole 10, the 4th containing hole 11 increases successively.
Connecting portion between described centre bore 12 and the 3rd containing hole 10 is formed for pressing down the pressing down section 13 of second magnet steel 9.
Because the containing hole 4 that through hole 1 of the present utility model is differed by a plurality of continuous apertures is formed, and the axial line of a plurality of containing holes 4 coincides, and makes the concentricity of when assembling the time can guarantee to assemble the preferably axial line of first magnet steel 5, anter 7, second magnet steel 9.
Be described in detail the assembling process of stereo set below.At first, first magnet steel 5 that scribbles glue is placed in first containing hole 6, the anter 7 that scribbles glue is placed in second containing hole 8, make the magnet steel 5 of winning bonding with anter 7, because the axial line of first containing hole 6 and second containing hole 8 coincides, therefore make the first bonding magnet steel 5 have concentricity preferably with anter 7.Treat again first magnet steel 5 to be magnetized after bonding step is finished.
Then, the first bonding magnet steel 5 and anter 7 taken off be placed on iron bowl 14 inside, second magnet steel 9 that scribbles glue is placed on the upper surface of anter 7, fill in slit between iron bowl 14 and the magnet steel with the lower port of magnetic circuit rule, make second magnet steel 9 snugly be positioned at the 3rd containing hole 10, and being used to of forming between centre bore 12 and the 3rd containing hole 10 pressing down section 13 that presses down second magnet steel 9 firmly second magnet steel 9 is pressed on the upper surface of anter 7.Because the axial line of the 3rd containing hole 10 and first containing hole 6 and second containing hole 8 coincides, make that mutually bonding first magnet steel 5, anter 7, second magnet steel 9 has concentricity preferably again.After finishing, this procedure again second magnet steel 9 is magnetized.
Compared with prior art, the concentricity of the axial line of first magnet steel 5, anter 7, second magnet steel 9 when the utility model not only can guarantee to assemble preferably makes that Distribution of Magnetic Field is even in the magnetic gap, and the efficiency of assembling that improved easy to assembly.
The foregoing description only is explanation technical conceive of the present utility model and characteristics; its purpose is to allow the personage that is familiar with this art can understand content of the present utility model and is implemented; can not limit protection range of the present utility model with this; all equivalences of being done according to the utility model spirit change or modify, and all should be encompassed in the protection range of the present utility model.
