Size-measuring clamping tool for automobile bulb filament
Technical field
The present invention relates to a kind of light bulb filament size-measuring clamping tool, especially relate to a kind of size-measuring clamping tool for automobile bulb filament.
Background technology
For adapting to the needs of vehicle safety travel, the light of automotive lighting distributes, illuminance all will reach certain requirement.Realize these requirements, except light fixture itself, the size of the luminous intensity of luminophor itself and size also play critical effect.And a kind of as light source of autobulb, the position that its filament must be positioned at regulation just can make distribution and the illumination of the light that light fixture sends reach requirement.Installation because of bulb on light fixture is located with lamp holder, the reference position when filament position of bulb also will be installed fixedly on light fixture take lamp holder is measured as benchmark, and also need wire, glass bulb transition between filament and lamp holder, can't directly measure filament with respect to the size of lamp holder reference position with testing tool, need use unit clamp to fix bulb and it is positioned when therefore measuring the light bulb filament size, the mode that fixes and positions of unit clamp directly has influence on the accuracy of light bulb filament dimensional measurement.
Summary of the invention
The purpose of this invention is to provide a kind of size-measuring clamping tool for automobile bulb filament, can carry out Measurement accuracy to automobile bulb filament, avoid the light bulb filament inaccuracy of dimensions of producing and cause pack into distribution and the illumination of the light that light fixture sends after light fixture of bulb undesirable.
For achieving the above object, the invention provides a kind of size-measuring clamping tool for automobile bulb filament, comprise and connect jig, bulb stationary fixture, testing standard part and surveying instrument test platform, described bulb stationary fixture is fixed in connecting hole on described connection jig, described testing standard part is positioned on described bulb stationary fixture, and described connection jig is fixed on described surveying instrument test platform.
Therefore, the present invention adopts the size-measuring clamping tool for automobile bulb filament of said structure, can carry out Measurement accuracy to automobile bulb filament, avoid the light bulb filament inaccuracy of dimensions of producing and cause pack into distribution and the illumination of the light that light fixture sends after light fixture of bulb undesirable.
Below by drawings and Examples, technical scheme of the present invention is described in further detail.

Embodiment
Embodiment
Fig. 1 is the structural representation of size-measuring clamping tool for automobile bulb filament embodiment of the present invention, as shown in Figure 1, comprise and connect jig 1, bulb stationary fixture 2, testing standard part 3 and surveying instrument test platform 4, bulb stationary fixture 2 is fixed in the connecting hole 11 that connects on jig 1, testing standard part 3 is positioned on bulb stationary fixture 2, connect jig 1 and be fixed on surveying instrument test platform 4, in the present embodiment, connecting hole 11 is circular.Fig. 2 connects the structural representation of jig 1 in size-measuring clamping tool for automobile bulb filament embodiment of the present invention, connect jig 1 and be connected the bayonet socket connector 12 that matches and the connecting hole 11 that is connected with bulb stationary fixture 2 with microscope, projector or other surveying instrument test platform for being fixedly connected with microscope, projector or other surveying instrument, being provided with.Fig. 3 is the structural representation of bulb stationary fixture 2 in size-measuring clamping tool for automobile bulb filament embodiment of the present invention, bulb stationary fixture 2 is used for bulb and is connected jig 1 being connected, the bulb connector 22 that also lamp holder can be fixed that is provided with the cylinder connector 21 that matches with connecting hole 11 and matches with the lamp holder shape.Fig. 4 is the structural representation of testing standard part 3 in size-measuring clamping tool for automobile bulb filament embodiment of the present invention, testing standard part 3 is metalworks identical with lamp holder localization part size and shape, be used for bulb is positioned, its length is determined apart from the length of lamp holder localization part according to light bulb filament, an axially open 31 identical with the reference axial direction position of bulb standard-required is arranged on it, the axial reference position of location light bulb filament, its top xsect 32 is used for the lateral fiducial position of location light bulb filament.
the present embodiment is when measuring, first will connect jig 1 is fixed on surveying instrument test platform 4, then the cylinder connector 21 on the bulb stationary fixture be connected on the connecting hole 11 that connects jig and fix, again the testing standard part is installed on the connector 22 of stationary fixture of bulb, with the axially open 31 of testing standard part and top xsect 32 locate light bulb filament axially and horizontal reference position, then testing standard part 3 is taken off, bulb is installed on bulb stationary fixture 2 again, the filament off-axis of the test platform of mobile test instrument test bulb to and the size of lateral fiducial position namely realized the bulb inside dimension is measured accurately.
It should be noted that at last: above embodiment is only in order to technical scheme of the present invention to be described but not be limited, although with reference to preferred embodiment, the present invention is had been described in detail, those of ordinary skill in the art is to be understood that: it still can be modified or be equal to replacement technical scheme of the present invention, and these modifications or be equal to replacement and also can not make amended technical scheme break away from the spirit and scope of technical solution of the present invention.
