Description
Technical field
The present invention relates to a kind of experimental examination device of auto parts machinery, especially relate to a kind of fatigue experimental device of automobile air-conditioning air outlet blades.
Background technology
At present in automobile, air-conditioning and air-conditioner air outlet are installed generally, blade and air door are installed on air-conditioner air outlet, stir thumb wheel about when people use to realize that the unlatching of air door is with closed.After door opening, stir the air port toggle by four direction all around, control and regulate from the cold air that flows out in air-conditioner air outlet or wind direction and the wind-force size of heating installation.Vehicle air conditioning outlet must be through a series of check, the use of just dispatching from the factory after the assay was approved before dispatching from the factory.Because the use of blade has repeated multiple timesly, so the torture test of blade is an important test.But the torture test of automobile air-conditioning air outlet blades is all generally to complete by artificial oscillating vane at present, inefficiency not only, accuracy is not high, and can not carry out the check under the specific conditions such as low temperature and high temperature, can't meet the check demand of most of producers.
Summary of the invention
Technical matters to be solved by this invention is: for the deficiencies in the prior art, provide a kind of fatigue experimental device of automobile air-conditioning air outlet blades.
The present invention solves the problems of the technologies described above the technical scheme adopted: the fatigue experimental device of automobile air-conditioning air outlet blades, comprise support stand, control box and be arranged on described support stand be used to the thumb wheel driving mechanism that drives the thumb wheel left rotation and right rotation be used to driving toggle reciprocating toggle driving mechanism all around, described thumb wheel driving mechanism all is connected with described control box electricity with described toggle driving mechanism, on described support stand, is provided with for vehicle air conditioning outlet fixing mounting groove is installed.
Preferably, described thumb wheel driving mechanism comprises rubber press, the briquetting supporting seat, housing screw, the first leading screw and thumb wheel limit switch, described the first leading screw is arranged on described support stand, described thumb wheel limit switch is electrically connected to described control box, described thumb wheel limit switch is arranged on the inboard and close described thumb wheel present position of described support stand, described briquetting supporting seat is connected with described the first leading screw, described rubber press is fixed on described briquetting supporting seat by described housing screw, after vehicle air conditioning outlet is installed and is fixed, described rubber press compresses thumb wheel.During use, rubber press compresses thumb wheel, and under the control of control box, the first leading screw rotates and drives the left and right to-and-fro movement of briquetting supporting seat, thereby rubber press is correspondingly left and right to-and-fro movement drive thumb wheel left and right reciprocating rotary also, realize that the unlatching of air door is with closed.The thumb wheel limit switch constantly passes to control box by the reciprocating signal in thumb wheel left and right, and the signal number of times that control box will be received adds up, and shows on its display screen, is the left and right to-and-fro movement cycle index of thumb wheel.In addition, rubber press hardness is softer, not only can protect better thumb wheel, and, more near the state of people's finger, can further improve the accuracy of test findings.
Preferably, described toggle driving mechanism comprises gear drive, the gear erecting frame, movable stand, toggle mounting blocks and the second leading screw, described movable stand comprises crossbeam, bottom bar, the first side plate, the second side plate, the first limit switch and the second limit switch, described the first limit switch and described the second limit switch all are electrically connected to described control box, described the first limit switch is arranged on the top of described gear erecting frame, described the second limit switch is arranged on a side of described gear erecting frame, described crossbeam is positioned at the top of described support stand, described the first side plate is fixedly connected with described crossbeam with described the second side plate, described support stand is provided with the first installing plate and the second installing plate, described bottom bar passes and is coupling in described gear erecting frame, described the first installing plate and described the second installing plate, described gear erecting frame is fixedly connected with described the first installing plate, described gear drive is arranged on described gear erecting frame and with described control box and is electrically connected to, the output gear of described gear drive and described the first side plate are coupling, described the second leading screw is arranged on described gear erecting frame, described the first installing plate is connected with described the second leading screw, described toggle mounting blocks is fixed on described crossbeam, in described toggle mounting blocks, be provided with the pickup groove for fixing described toggle.During use, under the control of control box, gear drive drives crossbeam and the toggle mounting blocks is made the front and back simple harmonic motion; The second leading screw rotates and drives the first installing plate left and right to-and-fro movement, thereby drives crossbeam and the left and right to-and-fro movement of toggle mounting blocks.Due to the control of control box and the effect of thumb wheel limit switch, the first limit switch and the second limit switch, in process of the test, a cycle of operation is: at first thumb wheel is opened, then before toggle → right → rear → left movement, last thumb wheel close, so circulation repeatedly, until torture test finishes.The first limit switch constantly passes to control box by the signal of simple harmonic motion before and after crossbeam, the second limit switch constantly passes to control box by the reciprocating signal in crossbeam left and right, the various signal number of times that control box will be received add up, on its display screen, show, be toggle before → right → rear → left to-and-fro movement cycle index.
Preferably, the arranged outside of described the second side plate has stiffening plate, and described stiffening plate and described the second side plate are coupling, and described bottom bar is two, and the end of two described bottom bars all is fixedly connected with described stiffening plate.When bottom bar is two, improve the stationarity of toggle side-to-side movement; Stiffening plate plays the effect of the weight of balance gear erecting frame, can protect better movable stand, the serviceable life of extension fixture.
Compared with prior art, the invention has the advantages that: the fatigue experimental device of automobile air-conditioning air outlet blades of the present invention, be provided be used to the thumb wheel driving mechanism that drives the thumb wheel left rotation and right rotation be used to driving toggle reciprocating toggle driving mechanism all around, therefore when using the present invention to carry out torture test to automobile air-conditioning air outlet blades, can realize the hollow motion repeatedly of toggle, thereby the horizontal blade group of vehicle air conditioning outlet and vertical vane group can both be moved fully repeatedly.Therefore adopt the accurately actual service condition of simulated automotive blades at air outlet of air conditioner of torture test that the present invention carries out, and can realize the torture test under the various temperature conditions such as low temperature and high temperature (the theoretical work temperature range is-40 ℃ ~+95 ℃) or other test condition, the corresponding fatigue test results drawn is the fatigue state of reality more, makes manufacturer make accurate judgement to the fatigue performance of automobile air-conditioning air outlet blades.
