Description
Technical field
It the utility model is related to a kind of commercial truck turning rack heart axis hole and examine special tooth rule.
Background technology
The measurement in aperture and thread depth for screwed hole measures usually using special etalon, in general
Standard tooth advises length about 150mm, than the length of standard when processing the multiple pit holes in position upper end of aperture and special operation condition in hole
Also deep, existing tooth rule can not just measure at all.
Utility model content
In order to solve this problem, the purpose of this utility model is to provide a kind of commercial truck turning rack inner axis of heart
Examine special tooth rule in hole.
A kind of technical scheme of the present utility model is：A kind of commercial truck turning rack heart axis hole examines special tooth
Rule, including handle, drift, no-go gage are provided with external screw thread on the drift, no-go gage, and the handle section is in regular polygon, handle
Outer surface is provided with annular knurl, and the no-go gage diameter is more than drift diameter, and the drift is connected through connecting shaft A with handle one end,
That end that connecting shaft A is connected with handle is provided with end difference, and the diameter of end difference is less than connecting shaft A diameter, end difference and company
Spindle A junctions form detection step surface, and the no-go gage is connected through connecting shaft B with the other end of handle, on the connecting shaft A
Limiting plate is arranged with, the limiting plate upper side side is provided with upper limit face, and opposite side is provided with Lower Limits face, and upper limit face is located at
Above Lower Limits face, upper limit face, Lower Limits face, limiting plate downside, detection step surface are horizontal plane.
Further, the handle, drift, no-go gage, connecting shaft A, connecting shaft B are concentric.
Further, the connecting shaft A peripheries are provided with external screw thread, set what is coordinated with connecting shaft A screw threads in the middle part of limiting plate
Screw.
Compared with prior art, the utility model has the advantages that：It is simple in construction, reasonable in design, measurable spy
Whether the thread depth and aperture on the position of different operating mode are qualified.
The utility model is described in more detail with reference to the accompanying drawings and detailed description.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure：

9- upper limits face；10- detects step surface；11- workpiece.
Embodiment
For features described above and advantage of the present utility model can be become apparent, special embodiment below, and coordinate accompanying drawing,
It is described in detail below.
As shown in figure 1, a kind of commercial truck turning rack heart axis hole examines special tooth rule, including handle, drift, only
Advise, be provided with external screw thread on the drift, no-go gage, the handle section is in regular polygon, and handle outer surface is provided with annular knurl, institute
State no-go gage diameter and be more than drift diameter, the drift is connected through connecting shaft A with handle one end, what connecting shaft A was connected with handle
That end is provided with end difference, and the diameter of end difference is less than connecting shaft A diameter, and end difference is formed with connecting shaft A junctions and detected
Step surface, the no-go gage are connected through connecting shaft B with the other end of handle, and limiting plate, the limiting plate are arranged with the connecting shaft A
Upper side side is provided with upper limit face, and opposite side is provided with Lower Limits face, and upper limit face is located above Lower Limits face, upper limit
Face, Lower Limits face, limiting plate downside, detection step surface are horizontal plane.
In the present embodiment, the handle, drift, no-go gage, connecting shaft A, connecting shaft B are concentric.
In the present embodiment, the connecting shaft A peripheries are provided with external screw thread, set in the middle part of limiting plate and match somebody with somebody with connecting shaft A screw threads
The screw of conjunction.
In the present embodiment, during measurement, if drift end can be screwed into bottom, and no-go gage end plug does not enter hole, then aperture is in qualified model
Enclose, if drift end can be screwed into bottom, detection step surface between upper limit face, Lower Limits face then thread depth in qualified model
Enclose, detection step surface be located on upper limit face or detect step surface be located at it is then unqualified under Lower Limits face.
The foregoing is only preferred embodiment of the present utility model, it is all done according to present utility model application the scope of the claims it is equal
Deng change and modification, it should all belong to covering scope of the present utility model.
