Specific implementation mode
With reference to Fig. 1 to Fig. 8 specific illustrative embodiments：
Electric vacuum pump with damping device, including vacuum pump ontology 6, which is characterized in that the vacuum pump ontology 6
Side is connected with cupuliform support plate 2, and cup-shaped cavity 21 is offered on the cupuliform support plate 2, and 21 interference fits are provided with master in cup-shaped cavity
Damper 3；The other side of the vacuum pump ontology 6 is connected with U-bracket 4, and cupuliform fixed seat is fixedly installed on U-bracket 4
5, main damper 3 is provided in cupuliform fixed seat 5；The both sides of the vacuum pump ontology 6 are arranged by main damper 3 in assembly
On fixing bracket 1.
Preferred embodiment is that cavity 31 is offered on the main damper 3, and assembly fixing bracket 1 includes shaped support 11,
One end of shaped support 11 is fixedly installed axis pin 12, the cavity 31 of one end and the main damper 3 on cup type support plate 2 of axis pin 12
It is connected；The other end of the shaped support 11 is connected with fixing piece 13, and one end and the master in cupuliform fixed seat of fixing piece 13 subtract
The cavity for shaking device is connected, and the other end of fixing piece 13 offers internal thread hole 14, and fixing piece passes through internal thread hole and connector
15 tighten and are assembled in shaped support.
Preferred embodiment is to be provided with square boss 16 on the fixing piece 13, square hole 17 is offered in shaped support,
When fixing piece is connected in shaped support, square boss is arranged in square hole.
Preferred embodiment is that there are three pin shaft holes 18 for setting on assembly fixing bracket 1.
Preferred embodiment is to be provided with limit shock absorber 7 on the cup type support plate 2.
Preferred embodiment is that the limit shock absorber 7 is provided with hexagon cavity 71 and dislocation equalization hole 72.
Preferred embodiment is, the cavity being arranged on the main damper 3 is that hexagon cavity 31 and two opposed dislocation are equal
Vestibules 32 are waited, step 33 is provided in the both ends of the surface of the main damper.
Assembly fixing bracket is welded as a whole by the axis pin of shaped support, and fixed main damper, and fixing piece passes through interior spiral shell
The external screw thread of pit and connector, which is tightened, to be assembled in shaped support.The square hole of shaped support structure design and the side of fixing piece
Shape boss coordinates, it is ensured that apply torque when assembling fixing piece with connector, meanwhile, play the centre of location position of fixing piece.At
Three pin holes being arranged on type holder, can arbitrarily weld two fixed pins, to realize that vacuum pump is rotated relative to setting angle
