Description
Technical field
The present invention relates to the automobile pick-up unit, particularly bush type of the quiet rigidity quiet rigidity detection device that suspends that suspends.
Background technology
The automobile suspension system is not only supporting whole power assembly, and plays important vibration isolation effect, and the vibration of engine is able to tangible reduction after being delivered on the car body by suspending.Simultaneously, suspending to reduce the transmission of high-frequency structure noise, and can have influence on the serviceable life of automobile power assembly and annex thereof.And these all with suspend an important parameter---quiet rigidity has direct relation.It is more to detect at present the suspend equipment of quiet stiffness parameters of bush type, but complex structure mostly costs an arm and a leg, and test operation comparatively bothers.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, easy to operate bush type quiet rigidity detection device that suspends, to satisfy the suspend detection requirement of quiet rigidity of bush type.
The bush type of the present invention quiet rigidity detection device that suspends comprises bearing, suspend anchor clamps and pressure transducer, is connected with push rod at an end of bearing, and the front end of push rod is equipped with jacking block, and jacking block can rotate around ejector rob axis with respect to push rod; The anchor clamps that suspend are fixed on the other end of bearing, and are arranged in the U-shaped piece, and a mandrel passes the clamping hole of the anchor clamps that suspend, and the mandrel two ends are supported on the two ends of U-shaped piece respectively; Described pressure transducer is connected between U-shaped piece and the jacking block.
The described anchor clamps that suspend are formed by connecting by bolt by two half block fixture blocks, on the opposite face of two half block fixture blocks, offer the surface and be the breach on the face of cylinder, the radian on this breach face of cylinder is consistent with the face of cylinder radian of the tested neck bush that suspends, and the breach on the two half block fixture blocks is formed the clamping hole of the anchor clamps that suspend.
Be fixed with bearing pin on the jacking block, the push rod front end offers axle center hole, and described bearing pin is positioned at this axle center hole.
Pressure transducer is connected with instrument, shows the force value that pressure transducer bore by instrument.During detection, the mandrel that will be supported on U-shaped piece two ends earlier takes out from the clamping hole of the anchor clamps that suspend, the U-shaped piece is separated with the anchor clamps that suspend, the tested neck bush that suspends is clamped in the clamping hole of the anchor clamps that suspend, then mandrel is passed the center pit of the tested neck bush that suspends, thereby U-shaped piece two ends are supported on the tested neck bush that suspends by mandrel.Afterwards, rotate push rod, push rod is moved forward vertically, because jacking block can rotate around ejector rob axis with respect to push rod, then push rod promotes the jacking block reach, and simultaneously, jacking block passes to pressure by pressure transducer, U-shaped piece, mandrel, the tested neck bush that suspends, the anchor clamps that suspend the other end of bearing successively.In this process, continuous rotation reach along with push rod, the instrument that is connected with pressure transducer will demonstrate the pressure data of continuous variation, note push rod displacement forward and corresponding pressure data, thereby can exert oneself relation curve with displacement, obtaining rate of curve in particular range is the quiet rigidity that this bush type suspends.
Bush type of the present invention suspends quiet rigidity detection device because its force application part---push rod and bearing spin by screw thread, and the increment of easy control keeps the location status of push rod easily in application of force process; And because jacking block can rotate around ejector rob axis with respect to push rod, thus jacking block push rod promote following work along ejector rob axis to mobile, thereby increased the accuracy of pressure transducer institute side data; This apparatus structure is simple, and the installation and the detecting operation of each parts are very convenient, can satisfy the suspend detection requirement of quiet rigidity of bush type.

Embodiment
Below in conjunction with accompanying drawing the present invention is described in further detail.
As Fig. 1, Fig. 2 and shown in Figure 3, this bush type quiet rigidity detection device that suspends comprises bearing 1, anchor clamps and pressure transducer 2 suspend, end at bearing 1 is connected with push rod 10, push rod 10 front ends offer axle center hole 12, and jacking block 9 is installed, be fixed with bearing pin 13 on the jacking block 9, this bearing pin 13 is positioned at the axle center hole 12 of push rod 10 front ends, making jacking block 9 be installed in push rod 10 front ends can rotate around ejector rob axis with respect to push rod 10, the rear end of push rod 10 is fixed with rotating disk 11, be provided with two planes that are parallel to each other on the push rod 10 vertically, at this upper edge, plane ejector rob axis to being marked with scale.
The anchor clamps that suspend are formed by connecting by bolt 8 by two half block fixture blocks 7, on the opposite face of two half block fixture blocks 7, offer the surface and be the breach on the face of cylinder, the radian on this breach face of cylinder is consistent with the face of cylinder radian of the tested neck bush 14 that suspends, after two half block fixture blocks 7 connected by bolt 8, the breach on it was formed the clamping hole 6 of the anchor clamps that suspend.
The anchor clamps that suspend are fixed on the other end of bearing 1 by studs 5, and are arranged in U-shaped piece 3, studs 5 and push rod 10 coaxial cables.A mandrel 4 passes the clamping hole 6 of the anchor clamps that suspend, and mandrel 4 two ends then are supported on the two ends of U-shaped piece 3 respectively, and described pressure transducer 2 is connected between U-shaped piece 3 and the jacking block 9.
During detection, the mandrel 4 that will be supported on U-shaped piece 3 two ends earlier takes out from the clamping hole 6 of the anchor clamps that suspend, U-shaped piece 3 is separated with the anchor clamps that suspend, the tested neck bush 14 that suspends is clamped in the clamping hole 6 of the anchor clamps that suspend, then mandrel 4 is passed the axle center hole of the tested neck bush 14 that suspends, thereby U-shaped piece 3 two ends are supported on the tested neck bush 14 that suspends by mandrel 4.Afterwards, rotate rotating disk 11 and drive push rod 10 rotations, push rod 10 is moved forward vertically, and push rod 10 will promote jacking block 9 reaches, simultaneously, jacking block 9 passes to pressure by pressure transducer 2, U-shaped piece 3, mandrel 4, the tested neck bush 14 that suspends, the anchor clamps that suspend the other end of bearing 1 successively.In this process, note push rod 10 displacement forward and corresponding pressure data, the relation curve with displacement of can exerting oneself, obtaining rate of curve in particular range is the quiet rigidity that this bush type suspends.
