Abstract
A standard lamp specially for calibrating a motor vehicle headlamp detector comprises an optical axis deflection mechanism; the optical axis deflection mechanism comprises a support and a rotary body rotating around the support; a spiral micrometer head is arranged between the support and the rotary body; a fixing support of the spiral micrometer is arranged on the support; an end portion of a micrometer screw rod of the spiral micrometer head presses against the rotary body and can push the rotary body to deflect; an elastic piece is arranged between the support and the rotary body; spring force of the elastic piece for the rotary body enables the rotary body to always keep a pressing state with the end portion of the micrometer screw rod. The advantages are that a deflection angle of the rotary body of the optical axis deflection mechanism is determined by a telescopic amount of the micrometer screw rod of the spiral micrometer head, and deflection angle error is very small.
Description
Technical field
The utility model relates to the standard lamp that is exclusively used in calibration motor vehicle head light detector luminous intensity and deflection angle.
Background technology
When the luminous intensity of motor vehicle head light detector and deflection angle are calibrated, need to use a kind of standard lamp.At present, the optical axis horizontal and vertical deflection mechanism of this standard lamp adopts leverage mostly, and moving fulcrum is many, and the gap of moving fulcrum junction is slightly large, causes the error of deflection angle larger.
Utility model content
The purpose of this utility model is to provide a kind of error standard lamp less, that be exclusively used in calibration motor vehicle head light detector of deflection angle.
The utility model is achieved in that a kind of standard lamp that is exclusively used in calibration motor vehicle head light detector, comprise optical axis deflection mechanism, the rotor that optical axis deflection mechanism is provided with support and rotates around support, between described support and rotor, be provided with spiral micrometer head, the fixed mount of spiral micrometer head is rack-mount, the top, end of the micrometric screw of spiral micrometer head is pressed on rotor and can promotes rotor deflection, between described support and rotor, be provided with elastic component, elastic component makes the end of rotor and micrometric screw remain top pressure condition to the elastic force of rotor.
As further improvement or preferred forms, the utility model also can adopt following attached technical scheme.
Distance from the pivot center of described rotor to the center line of described micrometric screw is 57.3 ± 0.05 millimeters.
Described optical axis deflection mechanism is divided into horizontal deflection mechanism and vertical deflection mechanism, and two deflection mechanisms are provided with described support and rotor separately, are provided with described spiral micrometer head and described elastic component between the support in same deflection mechanism and rotor.
The support of described vertical deflection mechanism is fixed on the rotor of described horizontal deflection mechanism, and the rotor of described vertical deflection mechanism is fixed on lamp box, and lamp box rotates with the rotor of vertical deflection mechanism.
The utility model has the advantages that, the deflection angle of the rotor of optical axis deflection mechanism determines by the stroke of the micrometric screw of spiral micrometer head, and the error of deflection angle is very little.

Fig. 1 is the one-piece construction schematic diagram of the utility model embodiment;
Fig. 2 is the mechanism principle figure of optical axis deflection mechanism;
Fig. 3 is the schematic diagram after the rotor deflection certain angle of optical axis deflection mechanism.
Embodiment
According to a kind of standard lamp that is exclusively used in calibration motor vehicle head light detector described in the utility model, as shown in Figure 1, there is a set of optical axis deflection mechanism, this optical axis deflection mechanism is divided into horizontal deflection mechanism and vertical deflection mechanism.Horizontal deflection mechanism mainly consists of support 1 and rotor 2, and support 1 is fixed on tripod 3, and rotor 2 can rotate around support 1.Vertical deflection mechanism mainly consists of support 4 and rotor 5, and rotor 5 can rotate around support 4.The support 4 of vertical deflection mechanism is fixed on the rotor 2 of horizontal deflection mechanism, and the rotor 5 of vertical deflection mechanism is fixed on lamp box 6, and lamp box 6 is with rotor 5 deflections.
No matter be horizontal deflection mechanism or vertical deflection mechanism, between support separately and rotor, be all provided with spiral micrometer head 7 and elastic component.Take vertical deflection mechanism as example, and referring to Fig. 2 and in conjunction with Fig. 3, the fixed mount 8 of spiral micrometer head 7 is arranged on support 4, and the top, end of the micrometric screw 9 of spiral micrometer head 7 is pressed on a jacking block 10 of rotor 5, and jacking block 10 is fixed on rotor 5.Along with the elongation of micrometric screw 9, micrometric screw 9 can promote rotor 5 deflections.The concrete structure of spiral micrometer head 7 is identical with the spiral micrometer head in milscale, and only the end face of micrometric screw 9 is arc surface.Between support 4 and rotor 5, be provided with elastic component, this elastic component consists of spring 11 and push rod 12, and spring 11 tops are pressed between support 4 and push rod 12, and push rod 12 tops are pressed on a jacking block 13 of rotor 5, and jacking block 13 is fixed on rotor 5.The elastic force of spring 11 makes rotor 5 and the end of micrometric screw 9 remain top pressure condition.By regulating the stroke of micrometric screw 9, the deflection angle of adjustable rotor 5.
Read for convenience the deflection angle of rotor, as shown in Figure 3, the distance R from the pivot center of rotor 5 to the center line of micrometric screw 9 is 57.3 ± 0.05 millimeters.In the situation that be no more than ± 5 degree of the deflection angle of rotor 5, as long as the reading of spiral micrometer head 7 be take millimeter as unit, just can directly using the reading of spiral micrometer head as the reading of deflection angle, and can meet the reading error requirement of standard lamp.For example, the reading of supposing the spiral micrometer head in Fig. 3 is 1 millimeter (namely S=1 millimeter), so just can think that the deflection angle α of rotor 5 equals 1 degree.
The embodiment of above-mentioned spiral micrometer head and elastic component, Shi Yi vertical deflection mechanism is example, but is equally applicable to horizontal deflection mechanism, repeats no more.
