Specific embodiment
It is right below in conjunction with the accompanying drawings and the specific embodiments to make the object, technical solutions and advantages of the present invention clearer
The present invention is described in detail.
Referring to figs. 1 to shown in Fig. 7, the invention provides a kind of bushing rigidity test frock, for drive rod 1 to be tested
Bushing 2 carries out fixing the bushing to be tested 2 during loading force, and bushing to be tested 2 includes inner sleeve and overcoat, inner sleeve and overcoat it
Between elastic connection, bushing rigidity test frock includes：Bushing fixed plate 10, offers bushing mounting holes 101, bushing to be tested 2
It is installed in bushing mounting holes 101, overcoat is fixed with bushing fixed plate 10；Connecting plate 20；
Bushing rigidity test frock includes two kinds of working conditions：Connecting plate 20 is fixed with the inner sleeve of bushing to be tested 2, is driven
(see figures.1.and.2 the first state that bar 1 is directed at bushing to be tested 2 radially and exerts a force to the loading of loading bushing fixed plate 10 institute
Show)；And connecting plate 20 is fixed with bushing fixed plate 10, drive rod 1 is directed at bushing to be tested 2 axially and inner sleeve loading is exerted a force
The second state (with reference to shown in Fig. 3)；Base 30, is arranged at bottom and the fixation connecting plate 20 of connecting plate 20.
Specifically, bushing rigidity test frock of the invention includes：Bushing fixed plate 10, connecting plate 20 and base 30.
Wherein, bushing to be tested 2 adopts a kind of body mount rubber bushing, its structure to include overcoat and inner sleeve, and jacket and inner sleeve is
The centre of steel bushing, overcoat and inner sleeve is rubber, and rubber is connect and through high temperature interference press-fit with metallic sheath with gluing.
During the first working condition, bushing to be tested 2 is entered in bushing fixed plate 10, the bushing of overcoat and bushing fixed plate 10
Installing hole 101 is fixed.When the inner sleeve of connecting plate 20 and bushing to be tested 2 is fixed, inner sleeve of the connecting plate 20 to bushing to be tested 2
Serve the effect of support.Now drive rod 1 is directed at bushing to be tested 2 radially and the loading of bushing fixed plate 10 is exerted a force, now
The force direction of drive rod 1 is directed towards the radial direction of bushing to be tested 2, because overcoat is fixed with bushing mounting holes 101, inner sleeve and company
Fishplate bar 20 connects, so when drive rod 1 exerts a force to the loading of bushing fixed plate 10, loading force can be delivered to by bushing fixed plate 10
Inner sleeve, and extrude the elastic component between inner sleeve and overcoat, it is possible to realize the X to bushing to be tested 2 to and the rigidity of Y-direction survey
Examination.
During the second working condition, connecting plate 20 is fixed with bushing fixed plate 10, and drive rod 1 is directed at bushing to be tested 2 axially
And inner sleeve loading is exerted a force.Now, the support bushing fixed plate 10 of connecting plate 20, drive rod 1 can be along the axle of accurate bushing to be tested 2
Loaded to internally set.Because overcoat is fixed with bushing fixed plate 10, along the axially loaded inner sleeve of bushing to be tested 2 when,
Axial test force is produced between inner sleeve and overcoat, the Z-direction rigidity of bushing to be tested 2 can be tested.Wherein base 30 is in work
When connecting plate 20 is supported and is fixed, it is ensured that connecting plate 20 test when be in a relatively steady state.
The bushing rigidity test frock of the present invention, it is possible to achieve the fixation to bushing to be tested so that bushing to be tested can
To meet the rigidity test of X, Y and Z-direction.In addition, the Fixture Design is rationally used cooperatively conveniently with bushing to be tested, carry significantly
The efficiency and accuracy of high test.
Furthermore, it is understood that bushing rigidity test frock, also includes：Connecting bolt, during the first state, bushing to be tested
Connecting bushing fixed plate 10 and the drive rod 1；During the second state, connecting bolt connects inner sleeve and drive rod 1.
Furthermore, it is understood that bushing fixed plate 10 is a rectangular slab with thickness, including two first for being oppositely arranged
Surface and second surface, are connected with side between first surface and second surface；Bushing mounting holes 101 connect first surface and the
Two surfaces；Screwed hole 102 is provided with side.When the first working condition, connecting bolt is spirally connected with screwed hole 102, the other end
It is spirally connected with the loading head of drive rod 1.So, when drive rod 1 exerts a force vertically downwards to the loading of bushing fixed plate 10,
The radial direction of alignment bushings installing hole 101, can test rigidity radially between inner sleeve and overcoat.During the second working condition, even
Fishplate bar 20 is spirally connected with screwed hole 102, support bushing fixed plate 10, covers in drive rod 1 pair and loads, and can test inner sleeve and outer
Rigidity between set vertically.
In addition, the both sides of bushing mounting holes 101 open up respectively a counter sink 103, coordinated with the nut for putting outward,
So as to realize the fixation to overcoat and bushing to be tested 2.
Used as a kind of preferred design, connecting plate 20 is two, and two connecting plates 20 are located at respectively bushing fixed plate
10 both sides, can so realize the stable support to inner sleeve or bushing fixed plate 10.
Specifically, connecting plate 20 includes：Part I and Part II, offer bolt hole on Part II；First
Part and Part II form a square.The connecting plate 20 of square can ensure that support strength.
Furthermore, it is understood that being provided with base 30：Two bar holes 301, between two bar holes 301 through hole is provided with
302.The section of base 30 is trapezoidal, and the length of the bottom surface of base 30 is less than the length of top surface.Trapezium structure is provided for base 30
Good support.There is through hole 302 middle of base 30, is easy to be assembled with miscellaneous part by bolt.The both sides of through hole 302
Bar hole 301 is provided with, is fixed with the Part II of connecting plate 20.Bar hole 301 can make connecting plate 20 horizontally slip, and adjust
The distance between whole two connecting plates 20, to meet the installation requirements of various sizes of bushing to be tested.The both sides banding of base 30
Close, to improve intensity.
