Embodiment
Below in conjunction with accompanying drawing, the embodiment of the invention is described in further detail.
See also Fig. 1 and Fig. 2, the three-dimensional measurement instrument 100 that the embodiment of the invention provides is to be used to measure for example exact instrument of the data such as thickness, curvature, off-centre of optical mirror slip of small-sized determinand.Described three-dimensional measurement instrument 100 comprises a measurement unit 10 and a probe assembly 20.
Described measurement unit 10 is a horizontal bearing platform, and it has a loading end 11, is used to carry determinand, and in the present embodiment, described determinand is an optical mirror slip 12.
Described probe assembly 20 comprises a probe 21 and a connection piece 22, and described probe 21 links to each other with described web member 22.Front end on the described probe 21 is a probe 211.Described probe 21 is conical.
Described probe 21 is fixed on the described web member 22.Have a light source 221 and an inductor 222 on described web member 22, in the present embodiment, described light source 221 and inductor 222 are arranged on the surface 220 of described web member.Described web member 22 be shaped as rectangle, described light source 221 and inductor 222 also can be arranged at any one side of described web member 22 or be arranged at respectively on some sides.Described light source 221 and described inductor 222 get final product facing to described measurement unit 10.
Between described inductor 222 and the described light source 221 for being electrically connected (figure does not show).Described inductor 222 can transmit electric signal and can receive described electric signal and control described light source switch (figure does not show) according to this signal for described light source 221, described light source 221 to start or close.Described inductor 222 is sensed when being placed with object on the described measurement unit 10, promptly sends an enabling signal to described light source 221, and described light source 221 receives this enabling signal and promptly starts light source switch, illuminates described measurement unit 10.When this object is finished by measurement, when shifting out described measurement unit, described inductor 222 also can induce on the described measurement unit 10 and not place object, promptly send a shutdown signal to described light source 221, described light source 221 receives this shutdown signal and promptly closes light source switch, thereby can close described light source 221.
In the present embodiment, described light source 221 is a led light source, and described inductor 222 is an infrared inductor.Described inductor 222 can be monitored the loading end 11 of described measurement unit 10, when being placed with object on the loading end 11 of sensing measurement unit 10, promptly starting light source 221 lights, illuminate the loading end 11 of described measurement unit 10, make regional brighter on the measurement unit 10, be convenient to the operator and operate probe assembly 20 and move on the determinand on the described measurement unit 10, make probe 211 touch determinand, be convenient to its various parameters are measured.
The slide rail 30 and one that is provided with perpendicular to described measurement unit 10 that further comprises of described three-dimensional measurement instrument 100 is parallel to described measurement unit 10 and the slide rail 40 of setting.Slide rail 40 is set to cruciform, and slide rail 30 is set to in-line.Described probe assembly 20 slide rail 40 is relatively done moving horizontally of direction all around, described probe assembly 20 also relatively slide rail 30 do the vertical moving of above-below direction.Therefore, the probe 211 that can operate described probe assembly 20 each position of moving to the determinand upper surface is carried out data and is measured.
