Abstract
The utility model relates to a test apparatus, in particular to a turn button switch endurance test apparatus used for performing an endurance test on a turn button switch mounted in an automobile. The test apparatus comprises a pedestal for fixing the turn button switch, a flexible rotating wheel in friction contact with a turn button portion of the turn button switch, and a stepping motor arranged on the pedestal and used for driving the flexible rotating wheel to rotate to make the turn button portion rotate towards an opposite direction relatively to the rotating direction of the flexible rotating wheel. By utilizing the stepping motor to drive the flexible rotating wheel to drive the turn button portion to rotate, the rotating angle of the turn button portion can be accurately controlled in a manner that the operation is simple, the structure of the turn button portion is not changed simultaneously, and the accuracy of the test is increased.
Description
Technical field
The utility model relates to a kind of test unit, relates in particular to a kind of rotary switch durability test apparatus that the rotary switch of installing on automobile is carried out long duration test.
Background technology
Rotary switch is due to easy to operate, uses very extensively on automobile, need to carry out long duration test to the knob of rotary switch when design, satisfies request for utilization to guarantee rotary switch.Existing rotary switch durability test apparatus is by perforate on knob, then insert a thin bar in this hole, driving the thin bar reciprocally swinging with cylinder again stirs rotary switch, due to the structure that can destroy knob when the perforate, reduce its intensity, affected the accuracy of test, and be difficult to carry out angular setting when directly promoting with cylinder, therefore existing rotary switch durability test apparatus exists the test accuracy low, unhandy defective.
Summary of the invention
For solving the deficiencies in the prior art, the utility model provides a kind of rotary switch durability test apparatus, and its experimental accuracy is high, and is easy to operate.
For achieving the above object, rotary switch durability test apparatus of the present utility model, the pedestal that comprises the fixed knob switch, also comprise with the flexible runner of the knob rubbing contact of rotary switch and be arranged on described pedestal and drive that this flexibility runner rotates so that knob with respect to the counter-rotational stepper motor of flexible runner.
As to restriction of the present utility model, be provided with the axis rotating shaft parallel with the axis of knob on pedestal, described flexible runner is the rubber wheel that is arranged in rotating shaft.
As to restriction of the present utility model, also comprise the pick-up unit that detects the stepper motor running status.
As to restriction of the present utility model, described pick-up unit comprises the approach switch that is fixedly installed on the fan-shaped sensing chip in rotating shaft and coordinates with this sensing chip.
As to restriction of the present utility model, be provided with the compressing tablet that compresses described rotary switch on pedestal.
Adopt technique scheme, its beneficial effect is as follows: drives flexible runner by stepper motor and rotate with drive knob section, the anglec of rotation of control handle section, simple to operate accurately, can not change the structure of knob simultaneously, improved the accuracy of testing; Pick-up unit is set can be detected the running status of stepper motor, guarantees to stop test when the stepper motor operation irregularity; Pick-up unit adopts sensing chip and approach switch, and simple structure is saved the space; Compressing tablet is set on pedestal is used for the fixed knob switch, can unclamp compressing tablet so that rotary switch is regulated, it is contacted reliably with flexible runner.

Fig. 3 is the schematic diagram of rotary switch to be detected;
Fig. 4 is the schematic diagram of compressing tablet in the utility model embodiment.
In figure: 1, pedestal; 2, flexible runner; 3, stepper motor; 4, rotating shaft; 5, sensing chip; 51, installation portion; 6, approach switch; 7, compressing tablet; 71, screw mounting hole; 8, rotary switch; 9, knob.
Embodiment
To shown in Figure 2, rotary switch durability test apparatus of the present utility model is used for rotary switch shown in Figure 38 is carried out long duration test as Fig. 1.This rotary switch 8 is rectangular structure, has a knob 9 columniform and part is exposed on its top, and this knob 9 can turn on several gears.This device comprises the pedestal 1 of fixed knob switch 8, this pedestal 1 is comprised of two L-type steel plates that separate to arrange, be provided with the compressing tablet 7 that is fixed this rotary switch 8 on pedestal 1, as shown in Figure 4, compressing tablet 7 becomes " several " font by the steel bar bending, the inside inclusion of compressing tablet 7 is on the shell of rotary switch 8, and the screw mounting hole 71 in compressing tablet 7 both sides is used for being connected with pedestal 1.Also be provided with a rotating shaft 4 on pedestal 1, be provided with flexible runner 2 in rotating shaft 4, and this rotating shaft 4 and an output shaft fixed connection that is arranged on the stepper motor 3 on pedestal 1, can be driven by this stepper motor 3.The axis of rotating shaft 4 is parallel to the axis of the knob 9 of rotary switch 8, and the flexible runner 2 that arranges in rotating shaft 4 is rubber wheel, this flexibility runner 2 and knob 9 rubbing contact, thereby when stepper motor 3 rotates, flexible runner 2 drives knob 9 and rotates, and both sense of rotation are opposite.When rotary switch 8 is installed, when knob 9 is fully contacted with flexible runner 2, then use screw in compression compressing tablet 7, guarantee that knob 9 and flexible runner 2 are in good bonding state all the time.
By the reciprocating rotary angle of control step motor 3, can be so that the knob 9 of rotary switch 8 turn to each gear, guaranteed the accuracy of test figure and comprehensive.Simultaneously, the pick-up unit of the running status that detects stepper motor 3 is set also between pedestal 1 and rotating shaft 4, can guarantees to stop test when stepper motor 3 abnormal.This pick-up unit comprises the fan-shaped sensing chip 5 that is fixedly installed in rotating shaft 4 and the approach switch 6 that coordinates with this sensing chip 5.The installation portion 51 that arranges on sensing chip 5 is fixedly connected with rotating shaft 4, its dual-side can swing under the drive of stepper motor 3, thereby alternately trigger approach switch 6, when motor 3 normal operation, approach switch 6 sends the induced signal of rule in a certain time interval, when motor 3 stalls or rotational angle occurs when inadequate, the induced signal that approach switch 6 sends also can be irregular, at this moment, can stop test, the security of warranty test.
Under the state of motor 3 normal operations, can carry out timing to the normal working hours of rotary switch 8, judge the situation of permanance according to the length of its normal working hours.
