Embodiment
With reference to Fig. 1 to Fig. 8 specific illustrative embodiments：
Electric vacuum pump with damping device, including vavuum pump body 6, it is characterised in that the side of described vavuum pump body 6
Cup support plate 2 is connected with, cup-shaped cavity 21 is offered on described cup support plate 2,21 interference fits are provided with main damping in cup-shaped cavity
Device 3；The opposite side of described vavuum pump body 6 is connected with U-bracket 4, and cup fixed seat 5, cup are fixedly installed on U-bracket 4
Main damper 3 is provided with shape fixed seat 5；The both sides of described vavuum pump body 6 are arranged on assembly by main damper 3 and fixed
On support 1.
Preferred embodiment is that cavity 31 is offered on described main damper 3, and assembly fixed support 1 includes shaped support 11,
One end of shaped support 11 is fixedly installed bearing pin 12, one end of bearing pin 12 and the cavity 31 of the main damper 3 on cup type support plate 2
It is connected；The other end of described shaped support 11 is connected with fixture 13, and one end and the master in cup fixed seat of fixture 13 subtract
The cavity of shake device is connected, and the other end of fixture 13 offers internal thread hole 14, and fixture passes through internal thread hole and connector
15 tighten and are assembled in shaped support.
Preferred embodiment is that square boss 16 is provided with described fixture 13, square opening 17 is offered in shaped support,
When fixture is connected in shaped support, square boss is arranged in square opening.
Preferred embodiment is that three pin shaft holes 18 are provided with assembly fixed support 1.
Preferred embodiment is to be provided with limit shock absorber 7 on described cup type support plate 2.
Preferred embodiment is that described limit shock absorber 7 is provided with hexagon cavity 71 and the impartial hole 72 that misplaces.
Preferred embodiment is that the cavity set on described main damper 3 is that the opposed dislocation of hexagon cavity 31 and two is equal
Deng vestibule 32, step 33 is provided with the both ends of the surface of described main damper.
Assembly fixed support, it is welded as a whole by the bearing pin of shaped support, and fixed main damper, fixture passes through interior spiral shell
The external screw thread of pit and connector, which is tightened, to be assembled in shaped support.The square opening of shaped support structure design and the side of fixture
Shape boss coordinates, it is ensured that fixture is being assembled with applying moment of torsion during connector, meanwhile, the centre of location position of a fixture.Into
Three pin-and-holes set on type support, can arbitrarily weld two steady pins, so as to realize that vavuum pump is mounted opposite angle rotation
90 degree.
Main shock absorber design, is molded using silicon rubber vulcanization, its both ends of the surface design step, is realized and is loaded cup in main damper
When in the cup-shaped cavity of shape support plate, end face rigidity reduces, and is advantageous to damping and assembling, and outside diameter is in interference fit with cup-shaped cavity,
During assembling, a small amount of water is applied, can be easily assembled；Six sides of hexagon cavity and the outside diameter interference of steady pin and fixture are matched somebody with somebody
Close, six corners are in gap state, are advantageous to rubber parts deformation apparatus with shock absorbing, reach damping purpose；Design two opposed mistakes
