Abstract
The utility model discloses a device for measuring depth of an internal thread, which comprises a screw, wherein the screw is provided with a vernier and scales, the vernier is also provided with scales, and the scales on the screw and the vernier are better to be the same with the scales on a vernier caliper so as to achieve the purposes of higher precision. The utility model aims at providing the device for measuring the depth of the internal thread, which has the advantages of simple structure, convenience, practicability and lower cost, and is easy to process and manufacture.
Description
Technical field
The utility model is about a kind of machine tool, and more particularly, it relates to a kind of device of measuring the internal thread degree of depth.
Background technology
Present internal thread, generally all attack with screw tap, machining is also arranged, but it is just difficult to measure internal thread coverage or significant depth, both having made this type of survey instrument also is to have precision not high, measure deficiencies such as inconvenience, thus up to the present, also less than the precision height, measure the instrument of internal thread depth survey easily.
Summary of the invention
The utility model has overcome the deficiencies in the prior art, and a kind of device of measuring the internal thread degree of depth is provided.
The purpose of this utility model is to be achieved by following proposal.
A kind of device of measuring the internal thread degree of depth of the present utility model, it comprises screw, and described screw is provided with vernier and scale, and vernier also is provided with scale, and the scale best and on the vernier caliper of the scale on screw, the vernier is the same, to reach the purpose of degree of precision.
The utility model has the advantages that:
1. simple in structure, easy to use;
2. be easy to make, with low cost;
Description of drawings
Figure A is an example structure front view of the present utility model;
Figure B is the viewgraph of cross-section of figure A.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
A kind of device of measuring the internal thread degree of depth, it comprises screw, and described screw is provided with vernier and scale, and vernier also is provided with scale, and screw is the same with the scale best and on the vernier caliper of the scale on the vernier, to reach the purpose of degree of precision.In implementing illustration A, B, screw (1) is provided with dovetail groove, can make the part of vernier (2) embed the dovetail groove of screw, and another part is in the outside of screw (1) external diameter, and vernier (2) can only moving axially along screw (1) like this; When the end face of screw (1) and vernier (2) when end face is concordant, the scale (3) of screw (1) is zero to zero with the scale (4) of vernier (2), this design is consistent with the scale design on the vernier caliper, when wanting screw (1) to screw in internal thread, when both having measured the internal thread degree of depth, because vernier (a 2) part is in the outside of screw (1) external diameter, can't follow up, can only be on the end face of internal thread, vernier (2) will endwisely slip with respect to screw (1), when screw (1) when stopping to screw in, because the end face of vernier (2) just is parked on the end face of internal thread, at this moment can be in scale (3), (4) directly read the length of screw screw-in internal thread on, also just known the significant depth of internal thread.
Claims (3)
1. a device of measuring the internal thread degree of depth comprises screw, it is characterized in that: described screw is provided with scale.
2. a kind of device of measuring the internal thread degree of depth according to claim 1, it is characterized in that: described screw is provided with vernier.
3. a kind of device of measuring the internal thread degree of depth according to claim 1, it is characterized in that: described vernier is provided with scale.
