Description
Technical field:
The utility model relates to the surveying instrument technical field, refers in particular to a kind of simple in structurely, measures convenient and accurate new type measuring instrument.
Background technology:
The development of micro-electromechanical technology has proposed more and more higher requirement to the precision positioning measurement, and high-precision metering feedback unit must have been arranged in the precision positioning measuring system.In real productive life, people are when measuring more tiny object, normally used measuring appliance is vernier caliper or spiral measuring instrument, its measuring accuracy is generally 0.05mm or 0.01mm, when needs are measured property more accurately, need accurate more measuring appliance, and the grating measuring instrument is normally used a kind of more accurate equipment of measuring.It is desk-top that present grating measuring instrument mostly is slide calliper rule, and its slidably guide rail by quadrature moves worktable in a plane, and its mode that moves can realize by modes such as manual or screw rods, and measure displacement data by the grating chi.Be the precision that guarantees to measure, itself manufacturing accuracy of the guide rail that is used to slide requires very high, but it inevitably scale error and mismatch error can occur in the process of production and processing and assembling, so just brings certain error for the result who measures, and has influenced the precision of measuring; And need continuous travelling table when measuring, operate very loaded down with trivial details, take a lot of trouble.
Summary of the invention:
The purpose of this utility model is to overcome the defective of prior art, provides a kind of simple in structure, and it is quite convenient to measure, and location survey new type measuring instrument accurately.
For achieving the above object, measuring instrument pedestal of the present utility model is provided with the optical projection system that is made of object lens, objective table and light source, and on pedestal, be equipped with and present the projection screen that optical projection system projects the workpiece image, the waffle slab of stack one printing opacity on the front of described projection screen, dividing on this waffle slab has some grids, forms the coordinate structure; Be mounted with the number implement of removable seizure grid and reading on the waffle slab lateral surface, number implement connects computer.
As the improvement of such scheme, described waffle slab is constructed by wafer board, and the grid on it is a square.
Described number implement is made of the traversing head that cooperatively interacts, reflective mirror and reading camera lens, and the reading camera lens electrically connects computer; Wherein traversing head is the assembly of an aiming image sensor and object lens, and the reading camera lens is the assembly of a reading image sensor and object lens.
After adopting such structure, in the workpiece projection imaging after on the projection screen, the coordinate system that utilizes waffle slab to constitute, catch grid on the waffle slab by traversing head during measurement, and the reading camera lens reads any number of squares of corresponding workpiece, with the image digitization of projection, and be transferred in the computer it is measured.And need not adopt grating chi in the reason grating measuring instrument, and also can or not cooperate the error that exists and have influence on the precision that the utility model is measured because of the table slide equidimension, easy and simple to handle, also save trouble.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is a partial structurtes enlarged drawing of the present utility model;
Accompanying drawing 3 is the partial enlarged drawing of waffle slab;
Accompanying drawing 4 is the enlarged diagram of traversing head to the workpiece image.
Embodiment:
Below in conjunction with accompanying drawing the utility model is described further:
See shown in the accompanying drawing 1～4 that the utility model comprises a pedestal 1, on pedestal 1, be provided with the optical projection system that constitutes by object lens 11, objective table 12 and light source 13, three's vertical design, light source 13 up, objective table 12 be positioned at the middle part, object lens 11 be positioned at the below.The projection screen 15 that can present workpiece that optical projection system projects 14 images is installed on pedestal 1, the waffle slab 2 of stack one printing opacity on the front of described projection screen 15, dividing on the waffle slab 2 has some grids 21, forms the coordinate structure.Be mounted with the number implement 3 of removable seizure grid 21 and reading on waffle slab 2 lateral surfaces, number implement 3 connects computer.
In the present embodiment, described waffle slab 2 is by wafer board structure, and the grid 21 on it is a square of the same size, in grid 21, can suitably increase bar code is arranged, mark such as numeral, be convenient to follow-up measurement and read.
Number implement 3 is made of the traversing head 31 that cooperatively interacts, reflective mirror 32 and reading camera lens 33, forms an integral body, realizes same moved further, and reading camera lens 33 electrically connects computer, can will handle in the data input computer that read.Traversing head 31 is the assembly of an aiming image sensor and object lens, has enlarging function, is convenient to the naked eyes aiming; Reading camera lens 33 is the assembly of a reading image sensor and object lens, and enlarging function is also arranged.
During measurement, workpiece 14 is placed on the objective table 12, be on the straight line with object lens 11, objective table 12 and light source 13, and light source 13 irradiation workpiece 14, object lens 11 receive and make it imaging.Projection screen 15 presents the image of workpiece that optical projection system projects 14, and this image is in the scope of waffle slab 2 just presents to the gauger.At this moment the mobile digital device 3, and certain on traversing head 31 alignment pieces 14 images is a bit caught, and Figure 4 shows that the enlarged diagram of traversing head to the workpiece image, realize certain some amplification on the image is improved the accuracy of measuring; And the corresponding grid 21 on the at this moment luminous mirror 32 reflection waffle slabs 2 makes it to enter reading camera lens 33, shown in the accompanying drawing 3, thereby realize image digitization by reading camera lens 33, and measure processing in the input computer, and and image data can be stored in the computer, be convenient to consulting or transmit in the future.So circulation, continuous mobile digital device 3 can be realized the measurement to workpiece 14 image differences on waffle slab 2, thereby obtains the relative dimensions of workpiece 14.Aiming image sensor and reading image sensor can be selected its pixel as required for use in the number implement 3, as adopt 800,000 pixels with the image sensor camera lens is the words of benchmark, its precision just can reach 0.0005mm-0.0025mm, and precision is quite high, and measuring operation is convenient.
The utility model need not be with the grating chi that need not adopt in the reason grating measuring instrument, and can not have influence on the precision that the utility model is measured because of the error of worktable, guide rail equidimension or cooperation existence yet, applicable to the workpiece of different shape, widely applicable, measure easy, the precision height.
