Abstract
The invention discloses an image measuring instrument with high measurement precision. The image measuring instrument comprises a CCD sensor, a glass platform and a guide rail stroke supporting platform. The image measuring instrument further comprises an air bearing. A to-be-measured workpiece is placed above the middle part of the glass platform. The CCD sensor is mounted above the to-be-measured workpiece. The glass platform is placed above a guiderail stroke supporting platform through supporting legs at four corners. The air bearing is mounted on the guiderail stroke supporting platform below the middle part of the glass platform. The distance between the air bearing and the glass platform is 3-8 [mu]m. The image measuring instrument has advantages of simple structure and convenient use. The image measuring instrument overcomes a problem of glass platform deformation of a large-stroke image measuring instrument caused by self gravity and weight of the to-be-measured workpiece, so that the flatness of the glass platform of the large-stroke image measuring instrument is kept consistent in measurement, thereby improving measurement precision.
Description
Technical field
The present invention relates to a kind of glass platform, the image measurer that specifically a kind of measuring accuracy is high.
Background technology
As shown in Figure 1, because needing the application end light during image application instrument measuring workpieces size, so the platform of image instrument is all based on glass table top, also owing to having end light below glass platform, so the point of suppon of glass platform all can only design on limit to prevent to the interference of end light, if glass table top is too big, owing to middle portion does not support, then the middle portion of glass platform will due to notch distortion under own wt, platform is more big or workpiece is more heavy then sagging more serious, make planeness excessive, the plane of glass platform cannot be parallel with guide rail stroke face, have impact on the accuracy of measurement.
Also not having solution at present, majority all takes software correction to maintain precision reluctantly.
Summary of the invention
It is an object of the invention to provide the image measurer that the measuring accuracy of a kind of structure sagging deflections simple, anti-is high, to solve in above-mentioned background technology the problem proposed.
For achieving the above object, the present invention provides following technical scheme:
The image measurer that a kind of measuring accuracy is high, comprise ccd sensor, glass platform and guide rail stroke and support platform, also comprise air-bearing, it is placed with workpiece to be measured above the middle position of described glass platform, described ccd sensor is arranged on the top of workpiece to be measured, described glass platform is placed on, by the feet of corner, the top that guide rail stroke supports platform, and described air-bearing is arranged on the guide rail stroke below the middle position of glass platform and supports on platform.
As the present invention's further scheme: the distance between described air-bearing and glass platform is 3-8 ��m.
Compared with prior art, the invention has the beneficial effects as follows:
Present configuration is simple, easy to use, the glass platform overcoming the especially image measurer of Long Distances is subject to the impact of self gravitation and workpiece weight to be measured and the problem be out of shape, the planeness of the glass platform of Long Distances image measurer is consistent when measuring, thus improves measuring accuracy.
Accompanying drawing explanation
Fig. 1 is the structural representation of prior art.
Fig. 2 is the structural representation of the present invention.
Embodiment
Below in conjunction with embodiment, the technical scheme of this patent is described in more detail.
Refer to Fig. 2, the image measurer that a kind of measuring accuracy is high, comprise ccd sensor 1, glass platform 2 and guide rail stroke and support platform 3, also comprise air-bearing 4, workpiece 5 to be measured it is placed with above the middle position of described glass platform 2, described ccd sensor 1 is arranged on the top of workpiece 5 to be measured, described glass platform 2 is placed on, by the feet 6 of corner, the top that guide rail stroke supports platform 3, described air-bearing 4 is arranged on the guide rail stroke below the middle position of glass platform 2 and supports on platform 3, and the distance between described air-bearing 4 and glass platform 2 is 3-8 ��m.
The high image measurer of described measuring accuracy is operationally, owing to the reactive force holder of air-bearing 4 is in the lower section of glass platform 2, glass platform 2 the gravity sag effect of glass platform 2 is eased, so that can not make sagging or distortion because of the weight of own wt or workpiece to be measured 5; Simultaneously owing to air-bearing 4 and glass platform 2 self-inspection exist the distance of 3-8 ��m, so the one-piece construction of survey meter and the work-ing life of glass platform 2 can not be affected, but air-bearing 4 plays a part support glass platform 2 discord glass platform 2 to be contacted, when platform rail moves, glass platform 2 is support but can not be worn.
Present configuration is simple, easy to use, the glass platform 2 overcoming the especially image measurer of Long Distances is subject to the impact of self gravitation and workpiece to be measured 5 weight and the problem be out of shape, the planeness of the glass platform 2 of Long Distances image measurer is consistent when measuring, thus improves measuring accuracy.
Above the better embodiment of this patent is explained in detail, but this patent is not limited to above-mentioned enforcement mode, in the ken that one skilled in the relevant art possesses, it is also possible under the prerequisite not departing from this patent objective, make various change.
