Abstract
The invention discloses a non-go gage used for detecting major diameter of a single gear. The non-go gage is characterized in that the main body (1) of the non-go gage is of a four-section type step structure, i.e. an anti-bumping cylindrical section (1a), an outer spline section (1b), a handholding cylindrical section (1c) and a positioning datum cylindrical section (1d), which are sequentially arranged from left to right, wherein the length of the anti-bumping cylindrical section (1a) is 8mm and the diameter of the anti-bumping cylindrical section (1a) is 22.30 <0>-0.1mm; the length of the outer spline section (1b) is 30mm, the major diameter of the outer spline section (1b) is 24.30<0.021>0mm, and the middle diameter of the outer spline section (1b) is 24.321<0>-0.003mm; the length of the handholding cylindrical section (1c) is 115mm; the length of the positioning datum cylindrical section (1d) is 10mm and the diameter of the positioning datum cylindrical section (1d) is 24.321<0>-0.003mm. The positioning datum cylindrical section is used for positioning, so that the outer spline section precisely detects the size of the major diameter of the single gear, whether the size of the major diameter of the single gear is more than specified upper deviation or not is effectively judged, and the non-go gage is simple in structure, easy to manufacture and convenient in detection and has very high practicability.
Description
Technical field
The invention belongs to large footpath detection field, specifically, particularly relate to a kind of no-go gage detecting the large footpath of monodentate.
Background technology
After monodentate splined hole completes processing, whether overproofly need to detect its large footpath size.Existing detection mode first utilizes optical microscope to obtain product image, then stopped the large footpath of manual type splined hole.The resolution obtaining product image due to optical microscope is low, just larger error is there is in the process in the artificial large footpath of acquisition splined hole, and the testing result that different testing staff draws may have very big-difference, completely different even, be badly in need of solving the problems of the technologies described above for this reason.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of no-go gage detecting the large footpath of monodentate, for improving accuracy of detection.
Technical scheme of the present invention is as follows: a kind of no-go gage detecting the large footpath of monodentate, it is characterized in that: the body (1) of this no-go gage is four-part form staircase structure, be followed successively by anti-damage cylindrical section (1a), outer spline section (1b) from left to right, hold cylindrical section (1c) and positioning datum cylindrical section (1d) formation, wherein: the length of described anti-damage cylindrical section (1a) is 8mm, and its diameter is
the length of described outer spline section (1b) is 30mm, and its large footpath is
its central diameter is
and described in hold cylindrical section (1c) length be 115mm; The length of described positioning datum cylindrical section (1d) is 10mm, and its diameter is
In above technical scheme, described positioning datum cylindrical section (1d) is for location, so that outer spline section (1b) accurately detects the size in the large footpath of monodentate, and then effectively judge whether the size in the large footpath of monodentate exceedes the upper deviation of regulation, and the structure of this no-go gage is simple, be easy to manufacture, easy to detect, there is good practicality.
The junction of described anti-damage cylindrical section (1a) and outer spline section (1b) is processed with relief groove, and described in hold cylindrical section (1c) periphery rolled reticulate pattern.
In said structure, described relief groove can conveniently be processed, and reticulate pattern is convenient to testing staff and is held.
Beneficial effect: positioning datum cylindrical section of the present invention is used for location, so that outer spline section accurately detects the size in the large footpath of monodentate, and then effectively judge whether the size in the large footpath of monodentate exceedes the upper deviation of regulation, and the structure of this no-go gage is simple, be easy to manufacture, easy to detect, there is good practicality.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described:
As shown in Figure 1, a kind of no-go gage detecting the large footpath of monodentate, the body 1 of this no-go gage is four-part form staircase structure, is followed successively by anti-damage cylindrical section 1a, outer spline section 1b from left to right, holds cylindrical section 1c and positioning datum cylindrical section 1d and form.Wherein: the length of anti-damage cylindrical section 1a is 8mm, and its diameter is
the length of described outer spline section 1b is 30mm, and its large footpath is
its central diameter is
and described in hold cylindrical section 1c length be 115mm; The length of described positioning datum cylindrical section 1d is 10mm, and its diameter is
the junction of described anti-damage cylindrical section 1a and outer spline section 1b is processed with relief groove, and the length of this relief groove is 2mm, and its external diameter is 18mm, and the periphery holding cylindrical section 1c has rolled reticulate pattern.
The foregoing is only preferred embodiment of the present invention, is not restriction with the present invention, and all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
Claims (2)
1. one kind is detected the no-go gage in the large footpath of monodentate, it is characterized in that: the body (1) of this no-go gage is four-part form staircase structure, be followed successively by anti-damage cylindrical section (1a), outer spline section (1b) from left to right, hold cylindrical section (1c) and positioning datum cylindrical section (1d) formation, wherein: the length of described anti-damage cylindrical section (1a) is 8mm, and its diameter is
