Specific embodiment
The embodiment of the present invention is described below in detail, the example of embodiment is shown in the accompanying drawings, wherein identical from beginning to end
Or similar label indicates same or similar element or element with the same or similar functions.It is retouched below with reference to attached drawing
The embodiment stated is exemplary, and for explaining only the invention, and is not construed as limiting the claims.
As shown in Figure 1 to Figure 3, engine front support fixation assembly provided in an embodiment of the present invention, including fore-stock 10,
One cushion 20, front support leg 30, the second cushion 40 and bolt 50.
Referring to FIG. 5, being provided with perforation 11 on fore-stock 10.
Referring to FIG. 6, and with reference to Fig. 2 and Fig. 3, be provided with eccentric orfice 21 on the first cushion 20；First cushion 20 card
Loaded in perforation 11, and the both ends of the first cushion 20 are located at the two sides of fore-stock 10.
Referring to FIG. 8, and with reference to Fig. 2 and Fig. 3, connecting hole 31 is provided on front support leg 30, bolt 50 passes through bias
It is fixedly connected behind hole 21 with connecting hole 31.The connecting hole 31 can be unthreaded hole, and the screw rod of bolt 50 can be with 31 mistake of connecting hole
It is full of cooperation；The connecting hole 31 or threaded hole, the screw rod of bolt 50 can by way of being screwed with the connecting hole
31 connections.
Referring to FIG. 7, and with reference to Fig. 2 and Fig. 3, the second cushion 40 is sheathed on the first cushion 20, and the second cushion
40 between fore-stock 10 and front support leg 30.
The present invention also provides a kind of for installing the engine front support fixation assembly of any embodiment of that present invention offer
Installation method, specifically includes the following steps:
First cushion 20 is installed in perforation 11.
Second cushion 40 is sheathed on the first cushion 20.
Front support leg 30 is placed on the second cushion 40.
Bolt 50 is passed through into eccentric orfice 21, and rotates the first cushion 20, so that bolt 50 is directed at connecting hole 31.
Bolt 50 is fixed in connecting hole 31.
From the above, in engine front support fixation assembly provided in an embodiment of the present invention, it only only used a bolt
50, therefore assembly efficiency when its installation is obviously accelerated, and assembly precision also improves；In addition, bolt 50 is with before in this implementation
It is not contacted directly between bracket 10, but soft contact is realized by the first cushion 20, therefore damping effect greatly improves；And it is preceding
Then it is isolated by the first cushion 20 and the second cushion 40 between stabilizer blade 30 and fore-stock 10, further improves damping effect
Fruit.That is, it is soft contact between remaining part that only bolt 50 and front support leg 30, which are rigid contact, in entire fixation assembly,
So compared to the prior art, damping effect is more preferably.
Due to being provided with eccentric orfice 21 on the first cushion 20, when bolt 50 pass through eccentric orfice 21, not with connecting hole
When 31 alignment, the position of eccentric orfice 21 can be changed by the first cushion 20 of rotation, so that bolt 50 is driven to rotate with it, with
Bolt 50 is aligned with eccentric orfice 21；This kind of structure setting, can be to avoid 40 skew of the second cushion.That is, before bolt 50 connects
When stabilizer blade 30 is connect with fore-stock 10, perforation 11 and connecting hole 31 a certain range of 360 is may be implemented in the first cushion 20 of rotation
The continuous adjustment of the rigging error of degree.The a certain range is determined by the eccentricity of eccentric orfice 21.
With continued reference to FIG. 6, the first cushion 20 includes the clamping section 22 being fixedly connected and linkage section 23, it is clamped section 22 and connects
The junction for connecing section 23 is formed with clamping platform 24；First cushion 20 is installed in perforation 11 by clamping platform 24.
Fig. 4 is please referred to as it can be seen that in fact, the second cushion 40 is to be sheathed on linkage section 23, it is preferable that the length of linkage section 23
The length less than the second cushion 40 is spent, then when the second cushion 40 is sheathed on the first cushion 20, the first cushion 20 and second soft
There is neutral gear between pad 40, which makes front support leg 30 only be in contact with the second cushion 40, and does not connect with the first cushion 20
Touching.This kind of structure design, allows the first cushion 20 that certain elastic deformation occurs, so that the processing for making up front support leg 30 misses
Rigging error brought by difference.In addition, the neutral gear is equivalent to an air bradyseism layer 60, it is therefore apparent that the air bradyseism layer 60
Bradyseism effect can preferably be improved.
Further, referring to FIG. 3, engine front support fixation assembly provided in an embodiment of the present invention further includes limit sleeve
70, limit sleeve 70 is sheathed on bolt 50, and is clearance fit between eccentric orfice 21.70 one side of limit sleeve plays restriction spiral shell
The effect of the position of bolt 50, in addition, due to being clearance fit, the first cushion between limit sleeve 70 and the internal diameter of eccentric orfice 21
20 also can use the gap adjustment bolt 50 alignment connecting hole 31, to increase the tune of bolt 50 on the basis of eccentricity
Whole range, preferably to guarantee that connecting hole 31 is aligned with bolt 50.
Further, with continued reference to FIG. 3, engine front support fixation assembly provided in an embodiment of the present invention further includes putting down
Gasket 80, flat shim 80 are sheathed on the screw rod of bolt 50, and flat shim 80 be located at bolt 50 nut and the first cushion 20 it
Between.Preferably, the cross-sectional area of the flat shim 80 is equal with the cross-sectional area of the first cushion 20, and the flat shim 80 is rigid material
Material is made, thus play the role of support and place the first cushion 20 be deformed.
Preferably, in order to increase slow vibration effect and support effect, between fore-stock 10 and the second cushion 40 and front support leg
30 and second plane-plane contact effect between cushion 40 it is optimal.
Therefore, referring to FIG. 5, fore-stock 10 includes support plate 12, perforation 11 is set in support plate 12；In support plate 12
It is provided with supporting plane 13；Second cushion 40 is provided with the first mating surface 41 close to one end of fore-stock 10；First mating surface 41
It is plane-plane contact between supporting plane 13.
Correspondingly, referring to FIG. 8, front support leg 30 includes mounting plate 32, mounting surface 33 is provided on mounting plate 32；Second is soft
Pad 40 is provided with the second mating surface 42 close to one end of front support leg 30；It is connect between mounting surface 33 and the second mating surface 42 for face face
Touching.
Be described in detail structure, feature and effect of the invention based on the embodiments shown in the drawings, it is above only
For presently preferred embodiments of the present invention, but the present invention does not limit the scope of implementation as shown in the drawings, all according to conception institute of the invention
The change or equivalent example modified to equivalent change of work should all when not going beyond the spirit of the description and the drawings
