Abstract
The utility model discloses a rearview mirror folding endurance test bench. The test bench comprises a working platform, an air cylinder, a rocker arm, a rack, a gear, a gear shaft, a rearview mirror installing plate and a toggle fork. The rearview mirror installing plate is installed on the working platform. The toggle fork is fixedly installed on the rocker arm. The rocker arm is installed on the gear shaft. The gear is installed on the gear shaft. The gear is engaged with the rack. One end of the rack is connected with a piston rod of the air cylinder. The structure is simple. The folding endurance of the rearview mirror can be detected. And a displacement sensor is arranged on the air cylinder. The displacement sensor is connected with a counter so that folding frequencies can be automatically recorded. Accuracy is high.
Description
Technical field
The utility model relates to a kind of rearview mirror testing table, relates to specifically the folding endurance test bed of a kind of rearview mirror.
Background technology
Automobile rearview mirror is the automotive safety part clearly stipulating in China's compulsory standard.At present, the test of rearview mirror is tested for heating properties, field range and the rearview mirror distortion rate of heating plate in the angular adjustment performance of minute surface, rearview mirror mostly, and detect less to the mechanical property of rearview mirror, and the testing table that does not exist the folding permanance of rearview mirror to detect on market, is difficult to the folding permanance of rearview mirror to test.
Summary of the invention
In order to solve the problems of the technologies described above, it is a kind of simple in structure, easy to operate that the utility model provides, the folding endurance test bed of rearview mirror that can detect the folding permanance of rearview mirror.
The technical solution adopted in the utility model is: comprise workbench, cylinder, rocking arm, tooth bar, gear, gear shaft, rearview mirror mounting plate and stir fork, described rearview mirror mounting plate is arranged on workbench, stir fork and be fixedly mounted on rocking arm, rocking arm is arranged on gear shaft; Described gear is arranged on gear shaft, wheel and rack engagement, and one end of tooth bar is connected with the piston rod of cylinder.
In the folding endurance test bed of above-mentioned rearview mirror, described cylinder is provided with displacement transducer, and displacement transducer is connected with counter.
In the folding endurance test bed of above-mentioned rearview mirror, described workbench is provided with tooth bar gathering sill, and tooth bar is through tooth bar gathering sill.
Compared with prior art, the beneficial effects of the utility model are: the utility model is simple in structure, can detect the folding permanance of rearview mirror, and, cylinder of the present utility model is provided with displacement transducer, displacement transducer is connected with counter, can automatically record folding times, and accuracy is high.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model.
Fig. 2 is vertical view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, 2, the utility model comprises workbench 1, cylinder 4, rocking arm 31, tooth bar 6, gear 5, gear shaft 51, rearview mirror mounting plate 2 and stirs fork 3, described rearview mirror mounting plate 2 is arranged on workbench 1, stir fork 3 and be fixedly mounted on rocking arm 31, rocking arm 31 is arranged on the upper end of gear shaft 51; Described gear 5 is arranged on gear shaft 51, and gear 5 engages with tooth bar 6, and one end of tooth bar 6 is connected with the piston rod of cylinder 4, and described workbench 1 upper bottom portion is provided with tooth bar gathering sill 11, and tooth bar 6 is through tooth bar gathering sill 11.Described cylinder 4 is provided with displacement transducer 41, and displacement transducer 41 is connected with counter 7.
When the utility model uses, rearview mirror mount pad is arranged on rearview mirror mounting plate 2, the mirror shell of rearview mirror adds to be held in to be stirred in fork 3, then open cylinder 4, cylinder 4 is with carry-over bar 6 flexible, tooth bar 6 engages with gear 5, therefore tooth bar 6 driven gear 5 reciprocating rotations, gear shaft 51 passes to reciprocating rotation to stir fork 3, stir folding the unfolding of fork 3 drive rear-view mirror shell, in process, displacement transducer 41 is to piston monitoring in cylinder, and record folding times by counter 7, until rearview mirror fatigue failure.
