Abstract
The utility model relates to a compressible test bed for durability of gas spring, wherein an upright column is fixed and wedded on the base, a sample supporting frame is fixed on the upright column by a bolt, and the sample supporting frame can be adjusted along the upper and lower directions of the upright column. A transmission shaft is connected with a decelerating machine by the flange of the decelerating machine. The transmission shaft is connected with a spline and a lower chain wheel. An upper chain wheel is connected with a door spindle by the spline. The door spindle traverses through a simulated back door and a heavy weight for door to drive the simulated back door to turn around the door spindle. A chain is equipped between the lower chain wheel and the upper chain wheel, and the chain is connected with the lower chain wheel and the upper chain wheel. The utility model can simulate completely the real situation of the tested gas spring assembly and do endurability tests under the conditions of all kinds of environment temperature, and provide precise data. The utility model has simple and convenient structure, easy manipulation.
Description
Technical field:
The utility model relates to a kind of compressible air spring endurance test bed, particularly relates to a kind of i.e. device of the endurancing under different high and low temperature environments of simulating compressible air spring assembly real work state.
Background technology:
At present, the air spring endurance test bed versions of giving ball-screw through speed reduction unit with transmission of power that adopt by stepper motor more, mainly there is the deficiency of three aspects in the air spring endurance test bed of this version.That is: the operative orientation of air spring for simply vertically, utilize to force external force to drive air spring to finish stretching and compression travel, can only carry out cold test.Because being mounted on the lifting door, the user mode of the reality of air spring assembly carries gravity, and the lifting door opened or close according to design angle, air spring is by behind the equilibrium point position of force characteristic curve simultaneously, stretching travel is finished by the lifting force of air spring self, and compression travel then relies on the gravitational torque of lifting door to finish.In addition, the air spring assembly is because the difference of environment for use is also proposing the very specific (special) requirements of temperature state test aspect the test temperature of endurancing.Thereby ball screw type durability of structures testing table can not reach the purpose of simulation air spring real motion state, can not satisfy the requirement that accurate data were provided for the serviceable life of parts.
Summary of the invention:
The purpose of this utility model is to provide a kind of compressible air spring endurance test bed, overcome air spring endurance test bed in the past and can not simulate the defective of air spring true user mode, this technical pattern can not only go out the actual working state of air spring by real simulation, but also can carry out simulation test to the dynamic life time under the high and low temperature environment.
The technical solution of the utility model is achieved in that compressible air spring endurance test bed, by adjustable base, column, sample stent with simulate tailgate etc. and form; Its central post is fixedly welded on the base, and sample stent is by being bolted on the column, and can prolong the adjustment of column above-below direction; Transmission shaft links to each other with reductor by the reductor flange; Driving shaft is connected with lower sprocket with spline; Upper sprocket wheel links to each other with door-hinge by spline, and door-hinge passes simulation tailgate and door counterweight counterweight, drives the simulation tailgate and rotates around door-hinge, is connected with chain between lower sprocket and the upper sprocket wheel.
Good effect of the present utility model is, simulates fully by the real work state of gas test spring assembly and carries out endurancing under the various ambient temperature conditions, can provide accurate test figure as design and use foundation, and this test platform structure is reasonable, and is convenient; Easy operating.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
Below in conjunction with drawings and Examples the utility model is further specified, compressible air spring endurance test bed is by adjustable base 1, column 2, sample stent 3 with simulate tailgate 4 etc. and form; Its central post 2 is fixedly welded on the base 1, and sample stent 3 is by being bolted on the column 2, and can prolong that column 2 adjusts up and down.Transmission shaft 5 links to each other with reductor by reductor flange 6; Driving shaft 7 is connected with lower sprocket 8 with spline; Upper sprocket wheel 9 links to each other with door-hinge 10 by spline, and door-hinge 10 passes simulation tailgate 4 and door counterweight counterweight 11, drives simulation tailgate 4 around door-hinge 10 rotations, is connected with chain between lower sprocket 8 and the upper sprocket wheel 9.As shown in Figure 1: earlier be assemblied in the two ends of air spring assembly on the sample stent 3 respectively and simulation tailgate 4 on, adjust the travel switch up and down of door, start the start button of external electrical control cubicles, motor and speed reducer begins operate as normal.Breakdown action: pass to the axle 5 that is in transmission connection behind the power that reductor joint flange 6 is accepted from motor and reductor and drive driving shaft 7 runnings, the bearing of power by last lower sprocket 8,9 passed to door-hinge 10 to be driven door openers 12 and falls, assist the air spring assembly by behind the equilibrium area, automatically be stretched to the designing requirement stroke by the gas test spring assembly, finish the stretching action of air spring, and will simulate tailgate 4 and open, finish breakdown action.Closing motion: pass to the axle 5 that is in transmission connection behind the power that reductor joint flange 6 is accepted from motor and reductor and drive driving shaft 7 runnings, the bearing of power by last lower sprocket 8,9 passed to door-hinge 10 drive simulation tailgates 4 by behind the equilibrium region of air spring assembly, simulation tailgate 4 joins together to bear the effect of gravitational torque together with the weight of door counterweight counterweight 11, the air spring assembly is compressed, close until simulation tailgate 4, finish closing motion.For finishing the dynamic life test of high and low temperature environment therapeutic method to keep the adverse qi flowing downward main assemblage of spring, this testing table adopts power output and mechanical driving part can be connected the design proposal of use at a distance, that is: mechanical driving part and air spring assembly together place in the large-scale environmental test chamber, carry out height simultaneously, the dynamic life test of low temperature alternation condition, and be in power output under the normal temperature state, by one through height, in the low temperature environment test tank wall, outer transition bracket, transmission of power to the mechanical part in the high-low temperature chamber, has been realized the dynamic test purpose under the high and low temperature environment.
