Abstract

The utility model relates to a high accuracy flatness measuring apparatu belongs to one kind and carries out measuring instrument to the work piece plane degree, and it mainly comprises mechanical measuring device, sensing signal conversion circuit and display, compares with prior art, has low in manufacturing cost, measurement accuracy height, measuring speed fast, difficult wearing and tearing and application scope advantage such as wide.

Description

A kind of high precision planeness measuring instrument
Technical field:
The utility model relates to a kind of high precision planeness measuring instrument, belongs to a kind of instrument that the workpiece planarization degree is measured.
Background technology:
At present, workpiece is carried out instrument and the method measurement of planeness, that comparatively use always two kinds: the one, and three coordinate measuring machine, the 2nd, platform adds the clearance gauge mode.Wherein, three-dimensional coordinates measurement flatness principle is: get more than 4 at planar point, calculate distance between the plane of the plane of the highest 3 formations and minimum 3 formations by computer software as the flatness value, three coordinate measuring machine (comprises portal frame by mechanical part, the marble platform, power transmission), switch board (comprises circuitry, the support software circuit board, sensor), computer and relevant Control Software are formed, accuracy of machines can guarantee in 0.01mm, measurement is adopted a little sensor life-time in 100,000 times, total cost is between 30~700,000 yuans, equipment investment is relatively more expensive, only be applicable to the measurement of high-accuracy size, for the measurement of typical products in mass production, work efficiency is also lower except investing costliness; The measurement plane degree principle that platform adds the clearance gauge mode is: workpiece is positioned on the platform, check that with clearance gauge distance between workpiece and the platform is as the flatness value, this method is comparatively commonly used, the measurement cost is low, high efficiency, but measuring accuracy is limited, degree of accuracy generally can only guarantee at 0.1mm, add that measuring process is mainly with people's manual manipulation, measurement result erroneous judgement chance is higher, and platform uses the back wearing and tearing comparatively fast with clearance gauge long-time, influences degree of accuracy, if workpiece surface quality requires high, platform and clearance gauge are drawn flower with surface of the work easily, in addition, just can't be suitable for when measuring flatness local in some workpiece planarization centre for need.
Summary of the invention:
The purpose of this utility model provides a kind of high precision planeness measuring instrument, and it can overcome the deficiencies in the prior art.
The utility model is achieved in that it mainly is made up of mechanical measuring device, transducing signal conversion circuit and display, wherein, mechanical measuring device is made up of frame, sensor, base standard piece, sensor, base standard piece are contained on the frame respectively, sensor connects the transducing signal conversion circuit, and the transducing signal conversion circuit connects display.
The utility model compared with prior art, have low cost of manufacture, measuring accuracy height, measuring speed soon, advantage such as not easy to wear and applied widely.
Description of drawings:
Fig. 1 is a fundamental diagram of the present utility model
Fig. 2 is the structural representation of the utility model mechanical measuring device
Embodiment:
As shown in Figure 1, 2, the utility model mainly is made up of mechanical measuring device 1, transducing signal conversion circuit 2 and display 3, wherein, mechanical measuring device 1 is made up of frame 4, sensor 5, base standard piece 6, sensor 5, base standard piece 6 are contained in respectively on the frame 4, sensor 5 have 3 and more than, base standard piece 6 has 3, sensor 5 connects transducing signal conversion circuit 2, and transducing signal conversion circuit 2 connects display 3.
During work, use the pairing plane of measured workpiece standard component in advance, be placed on and determine the workpiece reference field on three base standard pieces 7, and with sensor 6 zero setting, then workpiece is put on the mechanical measuring device 1, sensor 6 contacts with surface of the work, make sensor 6 produce a certain amount of mechanical shift, be converted to the displacement electric signal and be transferred to transducing signal conversion circuit 2, transducing signal conversion circuit 2 is carried out operational analysis to these displacement electric signal through amplifying, and draws measurement result, and be presented on the display 3, the operator can analyze the situation of change of each measurement point of workpiece according to the each point measurement data that shows, also can read the flatness integrated value that is drawn by these points.
