Abstract
The invention provides a measuring tool for measuring the pore diameter of an end cover, which is time-saving and labor-saving for judging whether a hole accords with requirement or not. The measuring tool comprises a measuring stick and is characterized in that: one end of the measuring stick is a go gauge end, the other end of the measuring stick is a no-go gauge end, the end part of the go gauge end is of a circular cone structure, the tail part of the go gauge end is of a cylinder structure, the diameter of a cylinder is sum of the standard dimension and the lower limit of variation, the end part of the no-go gauge end is of a circular cone structure, the tail part of the no-go gauge end is of a cylinder structure, the diameter of the cylinder is sum of the labeling dimension and the upper limit of variation.
Description
Technical field
The present invention relates to the technical field that motor is made, be specially the measurer in the aperture of measuring end cap.
Background technology
In the end cap manufacture process of motor, need bore hole on the end cap, the dimensional requirement in hole is accurate, and prior art is measured through professional equipment and is judged then whether it meets the requirements, and measuring process wastes time and energy.
Summary of the invention
To the problems referred to above, the invention provides the measurer in the aperture of measuring end cap, it is time saving and energy saving whether it meets the requirements the judgement hole.
Measure the measurer in the aperture of end cap, its technical scheme is such: it comprises measures rod, it is characterized in that: said of measuring rod is the no-go gage end for drift end, other end; The end of said drift end is a conical structure; The afterbody of said drift end is a column structure, and the diameter of said cylinder is standard size and lower limit of variation sum, and the end of said no-go gage end is a conical structure; The afterbody of said no-go gage end is a column structure, and the diameter of said cylinder is dimensioning and deviation upper limit sum.
After adopting structure of the present invention, fill in two of measuring rod respectively and treat in the gaging hole to judge whether the hole meets the requirements, time saving and energy saving.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
See Fig. 1, it comprises measures rod 1, and one that measures rod 1 is no-go gage end 3 for drift end 2, other end; The end of drift end 2 is a conical structure; The afterbody of drift end 2 is a column structure, and the diameter of cylinder is standard size D and lower limit of variation A sum, and the end of no-go gage end 3 is a conical structure; The afterbody of no-go gage end 3 is a column structure, and the diameter of cylinder is dimensioning D and deviation upper limit B sum.
