Specific implementation mode
In order to which the technical means, creative features, achievable purpose and effectiveness for making invention realize are easy to understand, with reference to
It is specifically illustrating, the present invention is further explained.
A kind of electric motor end cap brush box assembles riveting tool, as shown in Fig. 1~2, including cope plate 1 and lower template 2, it is described on
It is connected by least two guide rods 3 between template 1 and lower template 2；3 lower end of the guide rod is fixed in the lower template 2, upper end
Across the through-hole adapted to the guide rod 3 being arranged on the cope plate 1；Leading between the cope plate 1 and lower template 2
The first compression spring 4 is also arranged on bar 3；
The cope plate 1 is equipped with riveting mechanism, and the riveting mechanism includes the upper mounted plate being mounted on cope plate 1
11, the guiding pressure head 13 that is connect with fixed plate 11 by the second compression spring 12, upper end are mounted on fixed plate 11
Two guide posts 14, setting squeezes for two corresponding with 14 lower end of described two guide posts in the guidings pressure head 13
Sliding block 15；The guide post 14 is inserted into the jack for being oriented to and being adapted with the guide post 14 on pressure head 13, and the guiding is limited
Pressure head 13 is only capable of moving up and down along the guide post 14, and the guide post 14 passes through stroke limit structure and the guiding pressure head 13
Connection；14 lower end of the guide post is the cammed surface towards inside, is equipped in the guiding pressure head 13 and limits the extruding sliding block
15 are only capable of the sliding equipment to move along a straight line in the horizontal direction, are connected by third compression spring 16 between described two extruding sliding blocks 15
It connects, described two extruding sliding blocks 15 are pressed on 14 lower end of corresponding guide post by the third compression spring 16 respectively；The lower template 2
It is equipped with brush holder fixing device corresponding with the riveting mechanism, the extruding sliding block 15 is towards the one of the brush holder fixing device
End is equipped with the riveting portion 17 for riveting.
When brush box is assembled riveting using this tooling, the brush holder for being first loaded into brush box is placed on the brush holder fixing device
On, then apply external force and be pressed downward the riveting mechanism of cope plate by guide rod, come brush when riveting mechanism pushes and squeezes sliding block
When position by the fixed piece on earpiece of box, the guiding pressure head is moved toward one another with fixed plate under the blocking of brush box, described
The cammed surface of guide post lower end pushes down on the extruding sliding block, and two squeeze sliding block in the limitation lower edge level side of sliding equipment
To moving toward one another, the riveting portion is driven to move toward one another to collapse and squeeze smooth the fixed piece on earpiece of brush box inwardly.When
External force is removed after the completion of riveting, between cope plate and lower template, upper mounted plate and is oriented between pressure head and described two extruding
Between sliding block respectively first, second and third compression spring elastic reaction under reset, to facilitate riveting next time to operate.
So, by being oriented to the moving toward one another of pressure head and upper mounted plate, guide post and the inclined wedge for squeezing sliding block composition
Cooperate between structure and sliding equipment, squeeze sliding block arrive at brush box position when make riveting portion inwardly move towards by
Brush box fixed piece on earpiece inwardly collapse and squeeze it is smooth, disposably realize by pin bending and by brush box riveting in place two behaviour
Make, avoids and brush box fixed piece on earpiece is forced into riveted using impact force, brush box will not be caused to deform, not influence carbon brush in brush box
Movement, solve and be pressed hidden danger not in place, improve first-time qualification rate.
As a further optimization of the scheme , the sliding equipment includes the horizontal slide rail 18 being arranged being oriented to 13 inside of pressure head
And the sliding slot 19 coordinated with the sliding rail on the extruding sliding block 15 is set.
So by the way that the cooperation of sliding rail and sliding slot is arranged, two are allow to squeeze sliding block much smootherly in the horizontal direction
Move back and forth, keep the riveting process to the fixed piece on earpiece of brush box more stable, reduces out of order probability when riveting.
As a further optimization of the scheme , the stroke limit structure includes the limit being arranged on the guiding pressure head 13
Bar 110 and the positive stop strip hole 111 being arranged in the guide post 14 passed through by the gag lever post 110.The gag lever post 110
It is fixed on and is oriented on pressure head 13, the gag lever post 110 is moved up and down along positive stop strip hole 111 during riveting, the positive stop strip
The length in hole 111, which controls, is oriented to the distance that pressure head 13 moves in guide post 14.
So, the displacement distance for being oriented to pressure head is limited by stroke limit structure, on the one hand can prevent fixation
Plate be oriented to pressure head isolate and fall off, on the other hand can also indirect control two extruding sliding block between initial distance to adapt to not
Same brush box.
As a further optimization of the scheme , the brush holder fixing device includes brush holder fixed seat 21, is arranged and is fixed in brush holder
Locating core 22 for being positioned to brush holder and the brush box fixed block 23 for being positioned to brush box at 21 centers of seat.
When installing the brush holder with brush box, brush holder is placed in brush holder fixed seat, according to the position of locating core to riveting
Position is accurately positioned, and brush box fixed block determines the position of brush box.It so can be to avoid brush during riveting
Box is shifted or is deformed.
As a further optimization of the scheme , the riveting portion 17 is the fin extended downwardly, it is separately positioned on described two
Squeeze the bottom of the opposite inside of sliding block 15.The usual fin can be that the size of straight rib and its maximum outer profile is limited in institute
It states inside brush box, the fin can be arranged to be bent or adapt to the variously-shaped of the brush box according to the needs of riveting,
The fixed piece on earpiece of brush box is collapsed and squeezed smooth as long as can realize.
As a further optimization of the scheme , second compression spring 12 has multiple and surrounds the central shaft for being oriented to pressure head 13
It is uniformly distributed.In the upper groove adaptable therewith that the upper end of second compression spring 12 is arranged on fixed plate 11, under
End is arranged in the lower groove adaptable therewith on the guiding pressure head 13.Can make in this way guiding pressure head with it is fixed
Plate move toward one another more stablize, press fitting more precisely in place.
As a further optimization of the scheme , being also arranged with guide sleeve 31 on the guide rod 3, the guide sleeve 31 is mounted on described lead
3 inner side wall of through hole of bar, described first compression spring, 4 one end are arranged in lower template 2, and the other end is against the lower face of the guide sleeve 31
On.Guide sleeve can reduce friction and vibration, so that depression is more stablized smooth.
The foregoing is merely the preferred embodiment of the present invention, protection scope of the present invention is not limited in above-mentioned embodiment party
Formula, every technical solution for belonging to the principle of the invention all belong to the scope of protection of the present invention.For those skilled in the art
Speech, several improvement carried out without departing from the principles of the present invention, these improvement also should be regarded as the protection model of the present invention
It encloses.
