Description

Self-alignment contact measuring apparatus
Technical field
The utility model belongs to measuring equipment field, is specifically related to a kind of self-alignment contact measuring apparatus.
Background technology
Due to the develop rapidly of current science and technology, the appearance of new product, has higher requirement to measurement, and common demands repeatable accuracy will reach micron number magnitude, and individual other requires also high.Existing measurement mechanism is mainly used in on-line automatic measurement two plane-parallel differences in height and puts the distance of plane.Its measuring method is, measured object is located, is clamped on measurement mechanism, and coaxial with the director element of measuring sensor.
It is reference measurement element that measuring sensor forms one by two parts, this element and the larger plane contact of measured object.Another plane of a part of measuring sensor lower end and measured object or point cantact in addition, upper end contacts with survey sensor.During measurement, measuring sensor moves up and down under drive unit drives in director element, thus completes measurement.
The foozle of the positioning error of measured object and non-measured device is inevitably brought in measurement result by this measurement mechanism, and therefore its measuring accuracy is lower, and generally its duplicate measurements precision is on the 0.01mm order of magnitude.Such measurement result, can not meet the requirement of user at all.So it is extremely urgent for improving this measurement mechanism structure, improving its measuring accuracy.
Utility model content
The utility model is intended to the defect overcoming prior art, a kind of self-alignment contact measuring apparatus is provided, it eliminate the impact of the positioning error of measured object and the foozle of non-measured device, thus measuring accuracy is increased substantially, reduce the manufacturing accuracy of non-measured device, thus save manufacturing cost.
The technical solution of the utility model is as follows:
Self-alignment contact measuring apparatus, comprise reference measurement element 3, measuring sensor 4, force application element A5, force application element B12, survey sensor 6, actuating unit 7, director element 8, setting element 9, locating device 10, drive unit 11, reference measurement element is built with director element, measuring sensor is arranged in director element, locating device and force application element A is designed with, the contact of force application element A energy Reliable guarantee measuring sensor and measured object between reference measurement element and measuring sensor; Survey sensor is arranged on reference measurement member head, and its gauge head contacts with the upper surface of measuring sensor, and force application element B is placed between setting element and reference measurement element, to ensure the reliable contacts between reference measurement element and measured object; Setting element is fixedly connected with actuating unit by bolt, and actuating unit is provided with drive unit, and actuating unit moves up and down under drive unit drives.Measuring accuracy can increase substantially, and reduces manufacturing accuracy.
Further, be placed with by the measured object 2 of fixture 1 fixed clamp below reference measurement element and measuring sensor, fixture is fixed on the bottom of actuating unit 7.
Further, in measuring process, reference measurement element, measuring sensor and measured object remain reliable and natural fit-state completely.
Further, in measuring process, reference measurement element, measuring sensor and actuating unit depart from.
Compared with prior art, the utility model has following beneficial effect:
Self-alignment contact measuring apparatus can ensure that reference measurement element and measured object lower surface are reliably in best complete fit-state, and under the effect of force application element A, fit-state is stablized.When repetitive measurement, contact condition change is very micro-, and therefore measuring accuracy can increase substantially, thus the boosting appearance early of some new products.
Self-alignment contact measuring apparatus is depart from actuating unit 7 in measuring process, and therefore actuating unit foozle will not be entrained in measurement result, thus also further increase measuring accuracy.Reduce manufacturing accuracy, thus save manufacturing cost.
Self-alignment contact measuring apparatus is through the checking of producing and test, and the repeatable accuracy of 0.01mm traditional measurement mode maintained is brought up on the order of magnitude of 0.001mm, and measuring accuracy improves greatly.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the utility model self-alignment contact measuring apparatus.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the utility model, and be not used in restriction the utility model.
As shown in Figure 1, self-alignment contact measuring apparatus, comprise reference measurement element 3, measuring sensor 4, force application element A5, force application element B12, survey sensor 6, actuating unit 7, director element 8, setting element 9, locating device 10, drive unit 11, reference measurement element 3 is built with director element 8, measuring sensor 4 socket is arranged in director element 8, locating device 10 and force application element A5 is designed with, the contact of force application element A5 energy Reliable guarantee measuring sensor and measured object between reference measurement element 3 and measuring sensor 4.Survey sensor 6 is arranged on reference measurement element 3 top, and survey sensor gauge head contacts with the upper surface of measuring sensor 4.Force application element B12 is placed between setting element 9 and reference measurement element 3, to ensure the reliable contacts between reference measurement element and measured object.Setting element 9 is fixedly connected with actuating unit 7 by bolt, actuating unit 7 is provided with drive unit 11, moves up and down under the effect that actuating unit 7 drives at drive unit.Be placed with by the measured object 2 of fixture 1 fixed clamp below reference measurement element and measuring sensor, fixture is fixed on the bottom of actuating unit 7.In measuring process, reference measurement element, measuring sensor and element to be measured remain reliable and natural fit-state completely.In measuring process, reference measurement element, measuring sensor and actuating unit depart from.
Measuring principle: the measuring unit of " reference measurement element 3 ", " measuring sensor 4 ", " force application element A5 ", " survey sensor 6 ", " director element 8 " five parts compositions is contacted with the lower surface of measured object 2, make measuring unit depart from other object, impose suitable normal pressure simultaneously.This is just equivalent to an object to put on the surface of another object, adds certain power, makes the two fit completely, this laminating be from however reliably.If two objects relative position in repeatedly putting is constant, and does not have other External force interference, then its laminating situation also will remain unchanged, so in repetitive measurement, its measured value also can not change, thus improves measuring accuracy to greatest extent.
The measuring method of self-alignment contact measuring apparatus, comprises the steps:
(1) measured object 2 is placed on and fixture 1 locates and clamps;
