Abstract
The utility model discloses a groove depth measuring instrument. The instrument comprises a support bench and a dial indicator. The dial indicator is fixed on a central section of the support bench. The instrument of the utility model has the following advantages that the structure of the instrument is simple; manufacturing is convenient; the groove depth can be accurately measured so as to determine whether the groove accords with a design requirement.
Description
Technical field
The utility model relates to a kind of groove depth measuring apparatus.
Background technology
Whether measuring at present groove depth all is to use sample card to measure, consistent with sample card but sample card can only be measured groove, for the actual grade of groove with require the degree of depth to exist how many deviations to learn, whether the groove depth that also just can't draw reality meets designing requirement.
The utility model content
The purpose of this utility model is to provide a kind of groove depth measuring apparatus, can effectively solve to learn accurately whether the degree of depth of groove reaches the problem of technological requirement.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of groove depth measuring apparatus, comprise trestle table and dial gauge, and described dial gauge is fixed on the middle part of trestle table.
Preferably, described trestle table middle part has through hole, and the middle part of described dial gauge is located in the through hole, and the two ends of described trestle table are provided with feet; Reduce the contact area of trestle table and measured workpiece, reduce near the surface of tested groove to the impact of measurement result.
Preferably, described feet and trestle table are wholely set; Prolong the serviceable life of this instrument, make simultaneously measurement data more accurate.
Compared with prior art, the utility model has the advantages that: this apparatus structure is simple, and is easily manufactured, can accurately measure the groove groove depth to judge whether this groove meets designing requirement.
Description of drawings
Fig. 1 is the structural representation of a kind of groove depth measuring apparatus of the utility model.
Embodiment
Consult the embodiment that Fig. 1 is a kind of groove depth measuring apparatus of the utility model, a kind of groove depth measuring apparatus, comprise trestle table 1 and dial gauge 2, described dial gauge 2 is fixed on the middle part of trestle table 1, described trestle table 1 middle part has through hole 3, the middle part of described dial gauge 2 is located in the through hole 3, and the two ends of described trestle table 1 are provided with feet 4, and described feet 4 is wholely set with trestle table 1.
Measure the numerical value on plane, groove to be measured next door with this instrument by dial gauge 2 first, again 1 of trestle table is measured the numerical value of groove bottom lands on the plane on groove both sides by dial gauge 2, above-mentioned two numerical value are subtracted each other just can draw accurately groove groove depth.This apparatus structure is simple, and is easily manufactured, can accurately measure the groove groove depth to judge whether this groove meets designing requirement.
The above only is specific embodiment of the utility model, but technical characterictic of the present utility model is not limited to this, any those skilled in the art is in field of the present utility model, and the variation of doing or modification all are encompassed among the claim of the present utility model.
