Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with accompanying drawing and reality
Execute example the electrical machinery brush holder riveting set of the present invention is further elaborated.Should be appreciated that this place is retouched
The specific embodiment stated is only used for explaining the present invention, is not intended to limit the present invention.
Referring to figs. 1 through Fig. 3, electrical machinery brush holder riveting set one embodiment of the present invention includes upper die component and lower mold
Assembly, upper die component can move up and down by lower mold assemblies under the drive of aerostatic press or hydraulic press relatively；Upper mold
Assembly includes mould bases upper mold 2, mould bases joint 3, jacking block 9, slide block the 10, first spring 12 and the second spring
13, mould bases joint 3 is arranged in mould bases upper mold 2, and mould bases upper mold 2 connects aerostatic press by mould bases joint 3
Or the joint of hydraulic press, so that mould bases upper mold 2 is connected with the output shaft of aerostatic press or hydraulic press.
Jacking block 9 is connected with mould bases upper mold 2, and jacking block 9 is placed in the lower section of mould bases upper mold 2, and jacking block 9 arranges V
Shape groove, V-shaped groove is used for accommodating slide block 10 so that slide block 10 can move along V-shaped groove inwall, slide block 10
For riveting the salient point of workpiece (brush carrier), the quantity of slide block 10 is two, and two slide blocks 10 are at V
Being symmetrical arranged in shape groove, arrange the first spring 12 between two slide blocks 10, the first spring 12 is used for conflicting
Two slide blocks 10 so that two slide blocks 10 all contact with V-shaped groove.When electrical machinery brush holder riveting set is pressed down,
First spring 12 struts two slide blocks 10 so that it is contact with the V-shaped groove of jacking block；Jacking block 9 arranges V-shaped groove structure,
Ensure that, when jacking block 9 is pressed down, two slide blocks 10 synchronize toward intermediary movements.
Upper die component also includes guided mode plate 8, and guided mode plate 8 is movable with mould bases upper mold 2 to be connected, guided mode plate 8 energy
Enough relative mould bases upper molds 2 move up and down；In the vertical direction, the bottom surface of slide block 10 is with guided mode plate 8 partly
Overlapping, guided mode plate 8 is for spacing to slide block 10；Guided mode plate 8 is used for positioning sliding block 10, it is ensured that two slide blocks
10 in same level.
Second spring 13 is arranged between mould bases upper mold 2 and guided mode plate 8, for the reset of guided mode plate 8, electricity
When machine brush-holder riveting device is pressed down, it is ensured that guided mode plate 8 position is on the lower, it is simple to two slide blocks 10 strut.
Preferably, upper die component also includes baffle plate 11, and one end of upper baffle plate 11 is with mould bases upper mold 2 even
Connecing, the other end of upper baffle plate 11 is connected with jacking block 9,11 fixations of upper baffle plate.
Lower mold assemblies is used for carrying workpiece, and lower mold assemblies includes mould framing plate 1, mould bases guide rod 5, locating dowel 4
With lower mould bottom plate 7, wherein, mould bases guide rod 5, locating dowel 4 and lower mould bottom plate 7 are arranged at mould framing plate 1
On, mould framing plate 1 is fixed on the base plate of aerostatic press or hydraulic press；Lower mould bottom plate 7 is used for positioning workpiece,
Locating dowel 4, for spacing to mould bases upper mold 2, can be adjusted by the height of adjustment locating dowel 4 and press-fit height,
The last impulsive force of aerostatic press or hydraulic press is decomposed locating dowel 4 simultaneously, thus reduce slide block 10 and guided mode
The stress of plate 8, plays certain protective effect to the two part.
Arranging through hole in mould bases upper mold 2, mould bases guide rod 5 runs through described through hole, for entering mould bases upper mold 2
Row guide-localization.
As a kind of embodiment, it is described logical that upper die component also includes that slip cap 6, slip cap 6 are embedded in
In hole, mould bases guide rod 5 runs through slip cap 6.Because mould bases upper mold 2 replacement cost is higher, with slip cap 6 and mould
Sliding between frame guide rod 5 replaces the slip between mould bases upper mold 2 and mould bases guide rod 5, can improve on mould bases
The service life of mould 5.
The electrical machinery brush holder riveting set of above-described embodiment, during pressure down, is first guided mode plate 8 and lower mold
Base plate 7 contacts, and compresses the second spring 13, and guided mode plate 8 moves upward with slide block 10, slide block 10 and jacking block
The V-shaped groove contact of 9, makes two slide blocks 10 synchronize to move to centre, and compresses the second spring 13, two slide blocks 10
With the bump contacts of workpiece (brush carrier) during centre is moved, make the salient point of workpiece both sides to middle turning
Limit, when two slide blocks 10 contact, i.e. electrical machinery brush holder riveting set is just pressed onto position, and makes two workpiece closely
Fit together, also will be riveted together with brush carrier fixed plate by brush carrier.
The electrical machinery brush holder riveting set of above example, by changing the Impact direction of workpiece salient point, uses slide block
From the extruding of the side of salient point in the past, greatly reduce the stress of brush carrier internal chamber wall, solve brush carrier and riveting
The problem of deformation in journey, cancellation no-go gage ensures the deformation of brush carrier in riveting process；By adjust brush carrier with
The riveting height of brush carrier fixed plate, it is ensured that brush carrier does not loosens after riveting with brush carrier fixed plate, is riveting simultaneously
Cheng Wuxu ensures that brush carrier inner chamber size at brush carrier inner chamber no-go gage beyond the Great Wall, solves brush carrier and fixes with brush carrier
The problem that plate riveting loosens, Improving The Quality of Products, improves production efficiency；Thus reduce motor noise, improve
The performance of motor and life-span.
Embodiment described above only have expressed the several embodiments of the present invention, and it describes more concrete and detailed,
But therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that, for this area
Those of ordinary skill for, without departing from the inventive concept of the premise, it is also possible to make some deformation and
Improving, these broadly fall into protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be with appended
Claim is as the criterion.
