Abstract
The utility model discloses a quiet rigidity test fixture of engine shock attenuation cushion, it is with the sample clamping device that packs into that the characteristic is the quiet rigidity of engine shock attenuation cushion test to fix on compression test equipment, according to the requirement of sample product to sample pressurization, then slow loading and uninstallation, three continuous secondary compression. First compression is the pre -compaction to the sample to curve linear best in twice experiment in back is for reporting curve as a result. Get compression curve go up the deflection be 1 to 4 between the equidistance get 11 points to the deflection is the abscissa, uses load as the ordinate, obtains sharp slope with least spuares. This slope is the rigidity of cushion promptly. Play effect good at many things and expert in one. Can drill on the fixed plate according to the position of different shape cushion bolts, detect the cushion fast. It is with low costs, convenient to use.
Description
Technical field
The utility model belongs to mechanical manufacturing field, particularly a kind of engine damping cushion Static stiffness test fixture.
Background technology
For the model of different engine damping cushions because the bolt position of each cushion model and the size of cushion different, so to prepare various different fixed bolt hole support come for subsequent use.When we detect the rigidity of cushion, need to look for corresponding support to use according to the position of the bolt hole of cushion, bother very much, and the too much inconvenient FIXED MANAGEMENT of support.
Summary of the invention
The purpose of this utility model is to provide one to overcome above-mentioned existing problems, while detection vertical direction, again can detect force to and Y-direction, structure is simple, easy to manufacture, easy to use, a kind of engine damping cushion Static stiffness test fixture of accurate quick.
Technical solution of the present utility model is such, a kind of engine damping cushion Static stiffness test fixture, comprise fixed head, stiffening plate, base, gathering sill, pressure head and sample, it is characterized in that fixed head (1) and base (3) are by being welded to connect, angle between fixed head (1) and base (3) is provided with stiffening plate (2), fixed head (1) plate face has mounting hole, for installing sample (6), base (3) has gathering sill (4), for installing the detection position of fixing cushion, pressure head (5) is arranged on sample (6).
Gathering sill (4) has set bolt.
Pressure head (5) is arranged on sample (6) top, and sample (6) has the sample of different size model.
The mounting hole of fixed head (1) is the hole of off side.
Fixed head (1) is that soft material is made.
Advantage is compared with prior art:
1, effect good at many things and expert in one is played.
2, according to the position of difformity cushion bolt, fixed head can be holed, fast cushion is detected.
3, cost is low, easy to use.

Reference numeral: fixed head (1), stiffening plate (2), base (3), gathering sill (4), pressure head (5), sample (6).
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
Embodiment 1, the vibrations of diesel motor, greatly because rubber shock-absorbing cushion causes, the stiffness of its mainly rubber, and the cushioning ability of rubber mount is mainly reflected by the acting in conjunction of space three-dimensional rigidity.
The device of current detection rubber mount rigidity is made up of pressure head (5) and back up pad, rubber mount is put on the supporting plate, rigidity cushion detecting vertical direction Z-direction is pressed in pressure head (5), but can not detect to Y-direction X, the actual working state of damping cushion when can not reflect engine operation, and the sample diversified in specifications of each model cushion, is difficult to detect on same support, thus be difficult to the damping capacity evaluating cushion.
The test of engine damping cushion Static stiffness is that sample (6) is loaded clamp device, and is fixed on compression test equipment, pressurizes, then Slow loading and unloading by sample (6) product requirement to sample, continuous three second compression.First boil down to is to the precompressed of sample (6), and the later best curve of neutral line of testing for twice is for report result curve.Getting deflection on compression curve is equidistantly get 11 points between 1 to 4, is abscissa, take load as ordinate, obtain the slope of straight line with least square method with deflection.This slope is the rigidity of cushion.
Embodiment 2, Structure composing of the present utility model is:
1) this device is made up of fixed head (1), stiffening plate (2) and base (3);
2) fixed head (1) is drilled with the hole of diverse location, base (3) has two guiding grain (4);
3) fixed head (1) and base (3) are by being welded, and strengthen with stiffening plate (2);
4) according to the bolt position of difformity size cushion, in the upper hole of boring diverse location of fixed head (1), play a part fixing and support;
5) fixed head (1) is under the prerequisite meeting request for utilization, adopts the light material manufacture of sufficient intensity;
6) according to the cushion of different-thickness, by the effect of the upper gathering sill (4) of base (3), the detection position of cushion is accurately fixed;
7) first cushion is fixed on fixed head (1) when using, then passes through the effect of the upper gathering sill (4) of base (3), make pressure head of testing machine align cushion and detect position, then detect.
Embodiment 3, a kind of engine damping cushion Static stiffness test fixture, comprise fixed head, stiffening plate, base, gathering sill, pressure head and sample, it is characterized in that fixed head (1) and base (3) are by being welded to connect, angle between fixed head (1) and base (3) is provided with stiffening plate (2), fixed head (1) plate face has mounting hole, for installing sample (6), base (3) has gathering sill (4), for installing the detection position of fixing cushion, pressure head (5) is arranged on sample (6).Gathering sill (4) has set bolt.Pressure head (5) is arranged on sample (6) top, and sample (6) has the sample of different size model.The mounting hole of fixed head (1) is the hole of off side.Fixed head (1) is that soft material is made.
