Specific embodiment
With reference to Fig. 1 to Fig. 8 specific illustrative embodiments：
Electric vacuum pump with damping device, including vacuum pump body 6, which is characterized in that the vacuum pump body 6
One 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 opposite side of the vacuum pump body 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 body 6 are arranged on assembly by main damper 3
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, one end of axis pin 12 and the cavity 31 of the main damper 3 on cup type support plate 2
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 of shake 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 that square boss 16 is provided 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 the impartial hole 72 of dislocation.
Preferred embodiment is that the cavity set on the main damper 3 is equal for the opposed dislocation of hexagon cavity 31 and two
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 fixing piece is being assembled with applying torque during connector, meanwhile, the centre of location position of fixing piece.Into
Three pin holes set on type stent, can arbitrarily weld two fixed pins, be rotated so as to fulfill vacuum pump relative to setting angle
90 degree.
Main shock absorber design, is molded using silicon rubber vulcanization, and both ends of the surface design step is realized and is packed into cup in main damper
When in the cup-shaped cavity of shape support plate, end face rigidity reduces, and is conducive to damping and assembling, and outside diameter is in interference fit with cup-shaped cavity,
