The automatic edge extraction of feel, automatically removing burr, automatic measurement synthesis, so as to be provided with order where to walk where, automatic measurement；CNC walks,
Automatic measurement；The very excellent functions such as automatic study, measure batch.With the development of modern precision manufacturing technology, increasingly
More large-scale, ultra-large type precise thin-wall parts, software part need to detect, for traditional contact measurement means, Wu Faman
This demand of foot.Non-contact image measuring machine solves this problem, and it is to improve to select a kind of effective connected mode
Contactless big stroke image measuring measurement accuracy and stability important guarantee.
The content of the invention
Technical problem to be solved in the utility model, which is to provide one kind, can avoid motion over long distances from causing back and forth movement
Track is differed to error is brought, and can use high-precision line slideway by Y-axis head tree, the steel inside line slideway top shoe
Pearl size and how much directly back and forth movement track can be had influence on by shadow, so as to ensure the carrying of major and minor column on workbench
Weight one improves positioning accuracy and kinetic stability to property.
The utility model is achieved through the following technical solutions：A kind of non-contact super large stroke image measuring, bag
Workbench and the head tree being arranged on workbench, secondary column, crossbeam and Z axis are included, the crossbeam is installed on main vertical
The upper end of post and secondary column, Z axis are installed on crossbeam, and the bottom of head tree is supported and is oriented to by line slideway, and secondary column leads to
Air bearings support is crossed, air bearing is arranged at the bottom of air bearing push rod, and air bearing push rod upper end is connected with secondary column.
As preferable technical scheme, the line slideway is installed on workbench, and the bottom of head tree is connected with cunning
Block connecting plate, the lower end of the slide attachment plate are provided with sliding block, and the sliding block lower surface is provided with to be filled mutually with line slideway
The chute matched somebody with somebody, sliding block are installed in line slideway by chute.
As preferable technical scheme, the air bearing supports air bearing push rod by spherical pair.
The beneficial effects of the utility model are：The utility model uses the Y-direction of contactless super large stroke image measuring
Head tree use high-precision self-cleaning air bearing using high-precision line slideway and secondary column, and motion is more steady, improve grow away from
Cause back and forth movement track to differ to error is brought from motion, advanced or hysteresis phenomenon will not be formed.When optical amplifier sum
When word is amplified to up to 200 times, the image shown on screen quickly can be stablized and position, and this also directly improves contactless super large
The measurement accuracy and repeatability of stroke image measuring.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, drawings in the following description are only
It is some embodiments of the utility model, for those of ordinary skill in the art, is not paying the premise of creative work
Under, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is overall structure diagram of the present utility model；
Fig. 2 is that Y-direction air bearing of the present utility model adds line slideway installation diagram.
Embodiment
All features disclosed in this specification, or disclosed all methods or during the step of, except mutually exclusive
Feature and/or step beyond, can combine in any way.
This specification（Including any accessory claim, summary and accompanying drawing）Disclosed in any feature, except non-specifically chatting
State, can alternative features equivalent by other or with similar purpose replaced.I.e., unless specifically stated otherwise, each feature
It is an example in a series of equivalent or similar characteristics.
As depicted in figs. 1 and 2, including workbench 1 and the head tree 2, secondary column 5, horizontal that is arranged on workbench 1
Beam 3 and Z axis 4, crossbeam 3 are installed on the upper end of head tree 2 and secondary column 5, and Z axis 4 is installed on crossbeam 3, the bottom of head tree 2
Supported and be oriented to by line slideway 6, secondary column 5 is supported by air bearing 7, and air bearing 7 is arranged at air bearing push rod 8
Bottom, the upper end of air bearing push rod 8 is connected with secondary column 5.
As shown in Fig. 2 line slideway 6 is installed on workbench 1, the bottom of head tree 2 is connected with slide attachment plate 9,
The lower end of the slide attachment plate 9 is provided with sliding block 10, and the sliding block lower surface is provided with the cunning assembled mutually with line slideway
Groove, sliding block are installed in line slideway by chute, and air bearing supports air bearing push rod by spherical pair.
Super large stroke（Measurement stroke of the crossbeam span more than 2000 millimeters）This moving bridge structure image machine, Y-direction
Head tree uses high-precision self-cleaning air bearing using high-precision line slideway and secondary column, and motion is more steady, and positioning is more accurate
Really, the efficiency of measurement is greatly improved.Because secondary column is away from transmission system and frame of reference, along with major and minor on workbench
Column carrying varies in weight, it is easy to forms advanced or hysteresis phenomenon, causes position inaccurate and a small range to do back and forth
Motion.So it is to avoid motion over long distances from causing back and forth movement track to differ to bringing error, Ke Yitong to need to solve the problems, such as
Cross Y-axis head tree and use high-precision line slideway, steel ball size inside line slideway top shoe and how much can direct shadow shadow
Sound arrives back and forth movement track, so as to ensure that the weight one of the carrying of major and minor column on workbench to property, improves positioning accuracy
And kinetic stability.
The beneficial effects of the utility model are：The utility model uses the Y-direction of contactless super large stroke image measuring
Head tree use high-precision self-cleaning air bearing using high-precision line slideway and secondary column, and motion is more steady, improve grow away from
Cause back and forth movement track to differ to error is brought from motion, advanced or hysteresis phenomenon will not be formed.When optical amplifier sum
When word is amplified to up to 200 times, the image shown on screen quickly can be stablized and position, and this also directly improves contactless super large
The measurement accuracy and repeatability of stroke image measuring.
It is described above, only specific embodiment of the present utility model, but the scope of protection of the utility model is not limited to
