Abstract

The invention aims to provide a rigidity measuring clamp for an automobile rubber bush with strong commonality, which is used for measuring rigidity characteristics of the rubber bush. The rigidity measuring clamp for the automobile rubber bush comprises a framework and a rubber bush outer barrel fixing part which is movably arranged inside the framework; a rubber bush axial fixing part is installed at the side part of the framework; the framework is provided with a guide hole which is vertical to a moving direction of the rubber bush axial fixing part; and the rubber bush outer barrel fixing part is provided with an extension rod and the extension rod penetrates through the guide hole. When the rigidity measuring clamp is used for measuring, firstly a bush core shaft of the automobile rubber bush to be tested is clamped and fixed through using the rubber bush outer barrel fixing part; secondly, the rubber bush outer barrel to be tested is located and clamped through using the rubber bush outer barrel fixing part; and thirdly, loads and displacements between a measuring apparatus and the outer barrel are transmitted through using the extension rod. The rigidity measuring clamp for the automobile rubber bush, provided by the invention, is simple in structure and strong in commonality, and is capable of saving the clamp production time of engineering staff and greatly reducing the test development cost.

Description

A kind of rigidity measuring clamp for automobile rubber bush
Technical field
The invention belongs to the auto parts and components technical field of measurement and test, specially refer to a kind of rigidity measuring clamp for automobile rubber bush.
Background technology
Since the reform and opening-up, China's living standards of the people improve constantly, auto industry, logistics, and the road traffic building cause is flourish, domestic motor market constantly enlarges, and the automobile volume of production and marketing increases rapidly, and applying unit and consumer are improving constantly the requirement of the driving of vehicle, handling, riding comfort and NVH performance always.As the key components and parts in the chassis system, rubber bushing is responsible for transmitting the force and moment from all directions between the various beams of suspension, arm, bar structure and vehicle body or vehicle frame, the motion of constraint or guiding wheel, and isolation or decay are from vibration and the noise on road surface.And as the stiffness characteristics of one of important characteristic of rubber bushing, comprise radially, axially and the torsional rigidity of all directions, especially indispensable data in Automobile Design, CAE emulation and test development process.Because the rubber bushing on the automobile is more, and size dimension is generally not identical, when carrying out stiffness measurement, generally need to process the anchor clamps that match for each lining, not only prolonged the cycle of test and exploitation, also greatly increased cost.
Summary of the invention
The objective of the invention is to propose a kind of rigidity measuring clamp for automobile rubber bush of highly versatile, to be used for the measurement of rubber bushing stiffness characteristics.
Rigidity measuring clamp for automobile rubber bush of the present invention comprises framework and is movably set in the interior rubber bushing urceolus fixed part of framework, the sidepiece of described framework is equipped with rubber bushing axial restraint section, described frame installation has the pilot hole vertical with rubber bushing axial restraint section moving direction, described rubber bushing urceolus fixed part is provided with extension rod, and described extension rod passes pilot hole.
When measuring, at first utilize the be fixedly clamped lining mandrel of automobile rubber bush to be measured of rubber bushing axial restraint section, then utilize rubber bushing urceolus fixed part location and clamp rubber bushing urceolus to be measured, then by extension rod transmitted load and displacement between measuring equipment and urceolus.Above-mentioned screw rod can adapt to the lining mandrel of different length, has therefore improved versatility.
Further, described rubber bushing axial restraint section can change the position of rubber bushing axial restraint section for be installed on the screw rod of frame side by threaded engagement by rotating screw bolt, easy to adjust, and can clamp easily the lining mandrel.
Further, the end of described screw rod is pyramidal structure, and when being fixedly clamped the lining mandrel, the pyramidal structure of screw rod can stretch into the neck bush mandrel, avoids the dislocation of screw rod and lining mandrel.
Further, described screw rod has two, and symmetry is installed on the framework both sides, with the convenient position of adjusting automobile rubber bush to be measured, guarantees that rubber bushing urceolus fixed part can contact with the precalculated position of automobile rubber bush to be measured.
Further, described rubber bushing urceolus fixed part has two, and the symmetrical upper and lower that is installed on framework, with convenient at both direction simultaneously to the rubber bushing application of force, measure more comprehensive.
Further, the end of described rubber bushing urceolus fixed part is v-shaped structure, positions with convenient lining urceolus to different-diameter, thereby has solved the difficult problem of the anchor clamps versatility that produces because the lining size dimension is different.
Further, be provided with anti-slip veins in the v-shaped structure of described rubber bushing urceolus fixed part, to increase the friction force between rubber bushing urceolus fixed part and the automobile rubber bush to be measured, make between the two and can not produce relative sliding.
Rigidity measuring clamp for automobile rubber bush of the present invention is simple in structure, and highly versatile has been saved engineering staff's anchor clamps Production Time, also greatly reduces the pilot development cost.
