Description
Technical field
The present invention relates to machineries to survey and draw fixture fields, more particularly to a kind of height gauge.
Background technology
In production process, it is often necessary to be measured to the height of part.Measurement for general part height, use are general
Logical height gauge can be completed measurement, and height gauge includes pedestal and the fixed main scale on pedestal, guiding movement suit on main scale
There is a vernier scale, height gauge is placed on measuring table by when measurement, and moving cursor ruler makes its claw be stuck on the face to be measured of part
The height of part can be measured, but is frequently necessary to measure the relative altitude of some parts in actual production process,
As shown in Figure 1, needing to being measured with the relative altitude H between B at part A, existing measurement method is to survey respectively
The absolute altitude at A and at B is measured, the difference of the two numerical value is H, and this measurement method is not only troublesome in poeration, and repeatedly surveys
Amount is easy to that measurement error is made to increase.
In view of the above-mentioned problems, also occurring the height gauge for the relative altitude that some can directly measure part, example in the market
If notification number is 202903071 U of CN, the day for announcing is a kind of mechanical zero formula height disclosed in the Chinese patent of 2013.04.24
Ruler, the height gauge include pedestal and the main scale that is fixed on pedestal, and main scale is equipped with vernier and auxiliary scale, is set between auxiliary scale and main scale
Nut screw mechanism is set, so that auxiliary scale can be moved up and down relative to main scale, in use, the height gauge and part to be measured are placed
On measuring table, moving cursor ruler makes the reference plane of the relative altitude of its measuring jaw alignment element, then rotating nut leading screw machine
Structure is to drive auxiliary scale to move, until the auxiliary scale vernier graduation on vernier scale and the scale pair zero in auxiliary scale, then mobile trip again
On scale to the face to be measured of part, the relative altitude of part can be obtained by the scale cooperation on vernier scale and auxiliary scale.This
Kind height gauge is to ensure that auxiliary scale opposite can be moved up and down with main scale, and the depth of parallelism is wanted between main scale, leading screw and auxiliary scale three
The problem of asking higher, the accuracy of manufacture of height gauge thus made to increase, cost is caused to increase；And the nut of nut screw mechanism
There are gap between leading screw, which can be such that auxiliary scale is loosened relative to main scale, cause height gauge measurement result inaccurate in this way
The problem of；And the auxiliary scale of the height gauge and main scale interval are arranged, vernier scale is mounted on main scale, such vernier scale and auxiliary scale it
Between there is interval, error is larger when reading.
