Description
Technical field
The invention belongs to the offline inspection technical field of pole after finish turning, be specifically related to the simple detection device of a kind of bar circularity, linearity, be particularly well-suited to complete rapidly and accurately the reinspection of bar, predominantly detect the linearity of pole, circularity.
Background technology
In actual measurement work, through being commonly encountered the test problems of shaft-like workpiece form and position tolerance.Carrying out on the basis of key element and structural analysis, utilizing different survey tools, different detection methods can bring different testing results, and its accuracy of measurement and repeatability also can be otherwise varied.According to company's practical condition, the round bar of man of peripheral processing factory processing need to be carried out off-line and recheck to ensure that bar size meets production requirement, and recheck and predominantly detect circularity, linearity (both comprehensively can embody the cylindricity of bar).
Three coordinate measuring machine, cylindricity instrument and the three kinds of detecting instruments of measuring projector existed on market, all can detect the circularity of bar, cylindricity even linearity, and precision is higher, but for on-the-spot applying working condition, there is its limitation in it: three coordinates tables are measured, cylindricity instrument, its detection is by probe detection, its accuracy of detection is subject to measuring the requirement of environment, such as temperature, humidity, vibration problems etc., and it is relatively costly, and there is certain function waste for simply simple bar of rechecking, be more suitable for the detection of precision part.Measuring projector is the principle utilizing optical projection, is more suitable for the overall size and surface configuration that detect variously-shaped complex part, and stroke range is all less.
Can find to there is presently no on the market a suitable in diameter 40 ~ 80, length 700 ~ 1000 bar circularity and Instrument for Straightness in sum.
Summary of the invention
For overcoming above-mentioned the deficiencies in the prior art, it is an object of the invention to provide the simple detection device of a kind of bar circularity, linearity, the qualification rate of bar directly affects subsequent production, for the bar of periphery processing, to carry out reinspection be requisite operation, must also quickly finish the reinspection of high-volume bar simultaneously；No matter consider from on-the-spot applying working condition or the review requirements of conglomerate company, cost, operability etc., it is desirable to be able to simultaneously detection circularity and linearity based on platform signing method and the easy device meeting required precision.
For achieving the above object, the technical solution used in the present invention is: a kind of bar circularity, linearity simple detection device, include platform, platform is installed four parallel guide rails, linear electric machine switchboards of job guide rail, guide rail one, buncher switchboards of job guide rail and guide rail two；Linear electric machine switchboards of job guide rail is provided with linear electric machine and gauge stand two；Buncher switchboards of job guide rail is provided with buncher one and buncher two, and Biserial cylindrical roller bearing one connects buncher one and buncher two respectively, and Biserial cylindrical roller bearing two is seated on the bearing block of correspondence by another；Gauge stand one is seated on guide rail two.
Described Biserial cylindrical roller bearing one sets up separately at the two ends of bar to be detected with Biserial cylindrical roller bearing two.
The invention has the beneficial effects as follows:
When the present invention measures circularity, bar to be measured only need to be placed into above bearing and just can rotate under the drive of buncher, and now measurement table can move to diverse location measurement as required.When measuring linearity, by bar to be measured against guide rail, start linear electric machine, Linearity surveying can be completed.This detecting device can adopt master bar to verify, it is ensured that device overall precision controls within 5 μ.More time saving and energy saving than the detection of V-block method, efficiently convenient.High accuracy guide rail and high accuracy marble platform and installation accuracy control are the best guarantees that equipment plays superperformance.
The present invention has detection quick, accurate need to recheck the circularity of bar, linearity, with low cost, simple to operate, improves and rechecks efficiency and time saving and energy saving feature.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Referring to Fig. 1, marble platform 1 is installed four parallel guide rails, linear electric machine switchboards of job guide rail 2, guide rail 1, buncher switchboards of job guide rail 4 and guide rail 26；Linear electric machine switchboards of job guide rail 2 is provided with linear electric machine 11 and gauge stand 2 10；Buncher switchboards of job guide rail 4 is provided with buncher 5, and Biserial cylindrical roller bearing 1 connects buncher 5 respectively, and Biserial cylindrical roller bearing 29 is seated on the bearing block of correspondence by another；Gauge stand 1 is seated on guide rail 26.
Biserial cylindrical roller bearing 1 and Biserial cylindrical roller bearing 29 set up separately at the two ends of bar 12 to be detected.
Also include motor cabinet, bearing block.
Operation principle: 1) measure circularity: the length according to bar 12 to be detected, adjust the bearing block position of Biserial cylindrical roller bearing 29, bar 12 to be detected is put into above Biserial cylindrical roller bearing 1 and Biserial cylindrical roller bearing 29, dial gauge is installed on gauge stand 1, adjusting dial gauge makes its pointer touch on the surface of bar 12 to be detected, hand rotation workpiece, observe dial gauge whether suitable with bar 12 position to be detected, adjustment passes through governor control buncher 5 after completing, under the drive of frictional force, bar 12 to be detected starts to rotate, record the maximum difference that the pointer in this cross section beats and be the deviation from circular from this cross section, when next cross section surveyed by needs, mobile gauge stand 7 arrives correspondence position, take the deviation from circular from for this measured piece that cross section, each position point place all readings difference is maximum.
2) measuring linearity: after roundness measurement completes, close buncher 5, workpiece stops operating.Dial gauge is placed on gauge stand 2 10, bar 12 to be detected is contacted with guide rail 1 simultaneously, adjust the situation that contacts of dial gauge and bar 12 to be detected, start the difference of reading in linear electric machine 11 record pointer moving process after adjustment and can treat and detect bar 12 and carry out straight line degree measurement.
