Description
Technical field
The utility model belongs to a kind of detection auxiliary clamp, in particular to a kind of EMU interior trim rubber shock absorber specificity
Fixture can be detected.
Background technique
EMU interior trim rubber shock absorber is mainly used for the vibration damping drop of train seat as a kind of important damping element
It makes an uproar.It is good with effect of vibration and noise reduction, quality is small, can meet the strength and stiffness requirement of all directions, reduce rushing for vibration
Deformation is hit, the comfortableness and security of seating are improved.
But rubber material is easy to generate heat and generates thermal stress fatigue and aging phenomenon, this meeting under alternate load effect
So that the rigidity of rubber shock absorber, intensity and damping characteristic parameter are gradually deviated from design value, the vibration damping and anti-impact of damper are influenced
Performance is hit, and then influences the comfort taken.Therefore, it is necessary to a kind of detection fixtures to test the performance of damper.
As shown in Figure 1, a kind of interior trim rubber shock absorber 1 is mainly used in the vibration damping of train seat.The rubber shock absorber 1
Whole is in bowl-type, is made of support 2, rubber axle sleeve 3 and installation buckle closure 4, the outer surface of rubber axle sleeve 3 directly vulcanizes to support 2
Inner wall on, inner surface then vulcanizes onto central spindle 5, and the central spindle 5 and top installation buckle closure 4 are connect, and threaded hole 6 is provided in central spindle 5.
Due to the particularity of this 1 shape of damper, the detection of radial performance is carried out to the damper without suitable fixture.
Utility model content
In order to solve above-mentioned technical problem, the radial direction that the utility model provides a kind of EMU interior trim rubber shock absorber is dynamic
State detects fixture, which can simulate the performance test that actual use situation carries out damper, improve the precision of detection.
To achieve the goals above, the technical solution of the utility model is as follows:
A kind of EMU interior trim rubber shock absorber radial direction dynamic detection auxiliary clamp, including left bottom plate one, right bottom plate one, a left side
Bottom plate two, right bottom plate two, upper left pressing plate and upper right pressing plate；On the left bottom plate one, right bottom plate one, left bottom plate two and right bottom plate two
Equipped with through-hole；The through-hole diameter is 2mm bigger than the diameter of bolt；Rubber shock absorber is fixed on left bottom plate by through-hole by the bolt
One, on right bottom plate one, left bottom plate two and right bottom plate two.In use, two rubber shock absorber supports are opposite, screw rod is screwed into spiral shell
Pit, then two sides nut is tightened, the detection device of upper left pressing plate and bottom right pressing plate and top is connected, left bottom plate one, right bottom
Plate one, left bottom plate two, right bottom plate two are connect with the detection device of lower section, carry out the detection of performance.
In further embodiment, the left bottom plate one, right bottom plate one, left bottom plate two, right bottom plate two, upper left pressing plate and lower-left
Mounting hole is provided on pressing plate, to connect with detection device.
Through the above scheme, the radial detection fixture of EMU interior trim rubber shock absorber provided by the utility model is by left bottom
After seat one, right bottom plate one, left bottom plate two and right bottom plate two fix rubber shock absorber, screw rod is then screwed into rubber shock absorber,
Both sides nut is tightened, by the detection device of connection top and the detection device of lower section, carries out the test of performance.The clamp structure
Simply, easy for installation, improve the efficiency and precision of detection.

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Detailed analysis.
The utility model provides a kind of EMU interior trim rubber shock absorber radial direction dynamic detection fixture, as shown in figure 3, should
Fixture design is reasonable, structure is simple, has good detection accuracy.
EMU interior trim rubber shock absorber radial direction dynamic detection fixture as shown in Figures 2 and 3, including left bottom plate 1, the right side
Bottom plate 1, left bottom plate 29 and right bottom plate 2 10 are provided on left bottom plate 1, right bottom plate 1, left bottom plate 29 and right bottom plate 2 10
Mounting hole 17 is also provided on through-hole 11 and mounting hole 17, upper left pressing plate 15 and upper right pressing plate 16.
It is when using fixture, two 1 supports of rubber shock absorber are opposite, so that two bolts 12 is each passed through through-hole 11, by rubber
Glue damper 1 is fixed on left bottom plate 1, right bottom plate 1, left bottom plate 29 and right bottom plate 2 10, tightens nut 13.Then will
Screw rod 14 is screwed into rubber shock absorber 1, tightens two sides nut 14.Finally by mounting hole 17 respectively with the detection device of top and lower section
Detection device connection, connection after the completion of carry out EMU interior trim rubber shock absorber radial performance test.
EMU interior trim rubber shock absorber room temperature radial direction Static stiffness: radial loaded 0-1500N, preceding precompressed 1500N twice.The
The point of 800N, record displacement X are captured when loading three times1With power F1；The point of 1000N is captured, X is recorded2With F2。
Radial Static stiffness
Radial room temperature dynamic stiffness: apply the frequency of 20Hz, whole device is by precompressed 0mm, the case where amplitude is ± 0.5mm
Lower vibration detects the radial room temperature dynamic stiffness of EMU interior trim rubber shock absorber.
Above embodiment is intended merely to the utility model, and is not used as the restriction to the utility model, as long as
