Description
Technical field
The utility model relates to a kind of test fixture, particularly relates to a kind of test fixture of shock insulation piece.
Background technology
Shock insulation piece (having another name called Top Mount) is the rubber elastic element be installed between automobile absorber and body fixing point, mainly plays a part to be connected and fixed and damping.The sound rigidity of shock insulation piece is its main performance index, the height of sound rigidity can directly affect NVH performance, comfort property and the handling of vehicle, rigidity mainly is divided into radial rigidity and axial rigidity, and the performance of evaluation shock insulation piece is mainly by the examination of sport car road and lab investigation.At present, what the parts manufacturer mainly adopted is lab investigation, measuring These parameters and must use the dynamic and static measurement machine, and require installation and the stressing conditions of analog equipment on actual vehicle, is very high to the requirement of the design of experimental facilities ability and test fixture as can be seen here.
When the shock insulation piece is installed on actual vehicle, owing to affected by light weight, axially can be subject to preload force upwards, the preload force size is 1/4 of vehicle weight, so also require to load constant axial pre-load power when measuring radial rigidity (force-bearing situation of shock insulation piece when simulating vehicle swings), therefore generally to realize this test need to possess can load simultaneously two to testing apparatus, the comparison in equipment of single shaft power of test is general at present, and the experimental facilities of twin shaft, three axles is extremely expensive, cost performance is not high.Therefore the defect that existing equipment exists is:
1, can only do the single shaft test;
2, test fixture can't load axial force, can't realize the measurement of the radial rigidity of shock insulation piece axial pre-load power.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of test fixture of shock insulation piece, relatively simple for structure, and manufacturing cost is lower, can realize using single shaft that the part of preload requirement is arranged to the testing apparatus measurement.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of test fixture of shock insulation piece, described shock insulation piece comprises the rubber outer ring and is arranged at the inner core in the rubber outer ring, described test fixture comprises circle holding, U-shaped support, bolt, inner core block, starting stave, the second riser, the 3rd riser, connects cross bar,
Described circle holding is surrounded the rubber outer ring of shock insulation piece, and the axis of the axis of described circle holding and shock insulation piece coincides, and described circle holding is connected in external test facility,
Described U-shaped support comprises transverse slat and side plate, described side plate has two, described two side plates are vertically connected at the two ends of transverse slat, be respectively equipped with roller bearing on the inside surface of described two side plates, the axis of described each roller bearing is in same plane and perpendicular to the axis of circle holding, two roller bearings of described each side plate contact with the end face of circle holding respectively
The axis of described bolt and the axis of circle holding coincide, and described screw bolt passes connects starting stave, the inner core of shock insulation piece, inner core block, the 3rd riser and transverse slat,
Leave preset distance between the end face of the inner core of the end face of described inner core block and shock insulation piece,
Described the second riser is arranged at the below of circle holding,
Described connection cross bar is successively through connecting starting stave, the second riser, the 3rd riser, and described starting stave, the second riser, the 3rd riser are connected to external test facility.
Preferably, the roller bearing on each side plate of U-shaped support described in the utility model is two.
The preload force of axial constant can be converted into fixing displacement, concrete numerical value can be by power/Rigidity Calculation or inquiry force-displacement curve, first calculate the preload displacement while therefore testing, processing inner core block, making the preset distance left between the inner core end face of block end face and shock insulation piece is the preload displacement, then tight a bolt, the inner core that shrinks the shock insulation piece makes it be close to the inner core block, so far axial pre-load all is loaded on roller bearing, now test fixture being connected to testing apparatus can be tested smoothly, and radial direction can also be freely movable, the rigidity that guarantees radial direction also can be measured smoothly.
Therefore compared with prior art, the utility model has following beneficial effect:
(1) use existing equipment can complete test, do not need to purchase expensive twin shaft, three axle experimental facilitiess, saved the input of testing apparatus, reduced enterprise cost;
(2) can effectively solve the problem that loads axial pre-load power, can realize using single shaft that the part of preload requirement is arranged to the testing apparatus measurement;
(3) axial pre-load power all is carried in frock itself, and equipment can not be subject to the impact of side force;
(4) relatively simple for structure, cost of manufacture is lower.
