The utility model discloses having added the micrometer on original slide caliper's basis, having measured through the symmetry of micrometer and elongated activity masuring jaw alright counter shaft keyway, surveyed numerical value of a quantity and obtain the symmetry error of hole keyway through the conversion, this method is simple, and measuring range is wide, and measurement accuracy is high, and convenient and fast.
Description
Technical field
The utility model relates to a kind of survey instrument, specifically a kind of combined utensil measuring symmetry.
Background technology
Axle keyway symmetry is measured, and directly can affect the technical feature after key connecting assembling.At present, workshop processing site is generally measured with keyway feeler gauge the measurement of keyway.This measuring method is not high for keyway requirement on machining accuracy, substantially can meet the demands; Axle keyway symmetry measuring method is mainly measured with V shape iron, flat board, dial gauge and gauge stand common name signing method, and the method operation is not convenient, and measurement means is loaded down with trivial details, and precision reliability is poor.
Summary of the invention
Problem to be solved in the utility model is the deficiency overcoming above-mentioned prior art, provides a kind of structure simple, measures the combined utensil measuring symmetry accurately.
The utility model realizes as follows: a kind of combined utensil measuring symmetry, comprise main scale, on described main scale, cover has vernier, the below of described vernier is fixedly connected with the movable measuring jaw of lengthening, the front end of described main scale is connected with milscale by fixing measuring jaw, the front end of described milscale is provided with the measuring head that can put in and measure thing inside, described measuring head is positioned at the side near movable measuring jaw, the end face of described measuring head is parallel with the end face of movable measuring jaw, the end face of described measuring head and the axes normal of main scale; 0 scale of described main scale is provided with the block for limiting vernier stroke, and the distance between 0 scale of described main scale and fixing measuring jaw equals the range of milscale.
It is further: described measuring head is conical measuring head, and the large end of described measuring head is positioned at the side near movable measuring jaw.
The range of described milscale is 10mm.
Described main scale is provided with fine setting in the rear end of vernier.
Described vernier is provided with trip bolt.
The utility model has the following advantages: the utility model with the addition of milscale on the basis of original vernier caliper, the fixing measuring jaw of milscale and vernier caliper is fixed together, and lengthen the movable measuring jaw of milscale, just can be measured the symmetry of shaft key groove by the movable measuring jaw of milscale and lengthening, the numerical value measured obtains the symmetry error of hole keyway by converting, the method is simple, and measurement range is wide, measuring accuracy is high, and convenient and swift.
