Abstract
An adjustable wheel set assembling and clamping device comprises two assembling and clamping units. Each assembling and clamping unit comprises a linear wheel track, two symmetric bases, inclined blocks, top thread bolts and lead screws. Lugs are arranged on the two sides of each base, a circular hole is formed in each lug, threads are machined at the two ends of each lead screw, the diameter of each lead screw is matched with the apertures of the holes in the lugs on the two sides of each base, and the two ends, penetrating through the holes in the corresponding lugs, of each lead screw are fixed through bolts. The adjustable wheel set assembling and clamping device is characterized in that the two symmetric bases are connected with a shock excitation platform through the long circular holes in the two sides of each base, two threaded holes are formed in the face, parallel to a wheel set, of each base, the top thread bolts are matched with the threaded holes in the bases, long circular holes are formed in the inclined blocks, and the opposite sides of the two bases are connected with the inclined blocks through bolts. The appropriate assembling and clamping distance between each base and the wheel set can be adjusted; the adjustable wheel set assembling and clamping device is high in universality, reasonable in design, simple in structure, low in manufacturing difficulty and low in cost; during the whole vehicle vibration characteristic test and the hall vehicle self-vibration frequency test, the adjustable wheel set assembling and clamping device is convenient to install, test time is saved, work efficiency is improved, and accuracy of test data collection is ensured.
Description
Technical field
The present invention relates to a kind of test tool, more particularly, relate to a kind of right device of fixed vehicle steering framing wheel based on using in truck parameter measuring testing table vibration characteristics and natural frequency of vibration test.
Background technology
Truck parameter measuring testing table, has the ability of car load test of Vibration and the ability of half car natural frequency of vibration test, and the result of these two tests has vital function and significance to the design and optimization of vehicle.Before test, need the wheel on testing table whole clampings, vertical at platform, laterally and during rolling, should there is not relative displacement to the excitation platform of relative testing table in wheel, otherwise can affect the accuracy of test figure.Used integral type wheel is poor to chucking device versatility, when vehicle enters station, most existence are installed and do not mate, need to adjust, waste plenty of time, manpower, and delay test progress, also useful voussoir directly by wheel to blocking, the deficiency of this mode be installed not firm, and voussoir is easily shaken loosening when vibration test, directly affects the security of test figure and test.
Summary of the invention
Technical matters to be solved by this invention is to provide the right device of fixed vehicle steering framing wheel using in a kind of truck parameter measuring testing table vibration characteristics of simple in structure, highly versatile and natural frequency of vibration test.
For solving the problems of the technologies described above, the invention provides a kind of adjustable roller to chucking device, comprise two unit that are installed, each unit that is installed comprises a straight line wheel track, two symmetrical bases, skewback, jackscrew bolt and leading screw, base both sides are with ear, on ear, have circular hole, leading screw two ends are processed with screw thread, the diameter of leading screw mates with earhole aperture, base both sides, leading screw is bolted through the two ends of earhole, it is characterized in that: the slotted hole that two symmetrical bases have by both sides on it is connected with excitation platform, the right parallel surface of base and wheel has two threaded holes, jackscrew bolt mates with the threaded hole on base, on skewback, have slotted hole, two relative sides of base are bolted respectively skewback.
Base and straight line wheel track lap-joint have two U-shaped holes, while preventing from overlapping and straight line wheel track set bolt interfere.
The slotted hole that two symmetrical bases of the present invention have by both sides on it is connected with excitation platform, the right parallel surface of base and wheel has two threaded holes, jackscrew bolt mates with the threaded hole on base, two relative sides of base connect skewback by the slotted hole on skewback and bolt respectively, therefore adjustable base and wheel are to the suitable distance that is installed, highly versatile, simultaneously because base and skewback are bolted, while preventing vertical vibration, skewback has vertical deviation, reasonable in design, simple in structure, manufacture difficulty and cost are lower, in car load test of Vibration and the test of the half car natural frequency of vibration, install more convenient, saved test period, improved work efficiency, ensure the accuracy of test image data.

Embodiment
As shown in Figure 1, of the present invention wheel is arranged in existing parametric measurement testing table excitation platform I chucking device II, and limited wheel produces relative displacement to III and excitation platform I.
As Figure 2-Figure 5, described wheel chucking device II by straight line wheel track a, base b, skewback c, jackscrew bolt d and screw mandrel e form, this device is symmetrical centered by straight line wheel track a, described straight line wheel track a two wing bases have four bolts hole 1, by bolt and excitation platform I, fix, the distance of two straight line wheel track a is identical according to the gauge of detected vehicle, described base b and straight line wheel track a are joint form, base b and straight line wheel track a lap-joint have two U-shaped holes 9, while preventing from overlapping and straight line wheel track a set bolt interfere, the every side in both sides, base b bottom surface has two pairs of slotted holes 2, by bolt, be connected with excitation platform I, utilize slotted hole 2 adjustable base b and take turns the suitable distance that is installed, base b has two threaded holes 3 with wheel to parallel surface, d mates with jackscrew bolt, base both sides are welded with ear 4, on ear 4, have circular hole 8, above described skewback, have slotted hole 6, skewback c left and right can be adjusted, by bolt 5, fix with base b, while preventing vertical vibration, skewback c has vertical deviation.
As Figure 6-Figure 7, vehicle enters station, and it is normotopia that wheel falls into straight line wheel track a upper to III, be installed wheel to time, first adjust the base b appropriate location of wheel to III that be installed, base b is fixed in excitation platform I, then skewback c is filled in base b with wheel in the gap of spoke, jackscrew bolt d by skewback c tightly withstand on wheel on spoke, above skewback c, bolt and base are fixing tight, by two leading screw e, respectively through base b two circular holes 4, with bolt 7, leading screw e and base b is fixing tight, end is installed.
