Description
Technical field
The utility model relates to a kind of logical only one detection rule of internal screw thread, belong to mechanical design field, are suitable for automation
Detect threaded mounts.
Background technique
The logical only detection rule of the thread measurement mostly separated manual go-no go gauge of drift and no-go gage, two detectors are distributed in detection
The both ends of rule；And ununified structure type is advised in logical only one detection, and application is less.Currently on the market to thread quality
It is required that it is higher and higher, the demand of thread measurement is increased, sampling observation is no longer satisfied the demand of full inspection by hand, to automation screw thread
Detection device and detection rule put forward new requirements.There is no the logical only one detection rule of standardized screw thread, equal root on domestic market
It is customized according to demand.
Summary of the invention
The purpose of this utility model is to provide a kind of logical only one detection rule of internal screw thread, and the present invention is to logical only one detection
Facilitation is played in rule standardization, offers convenience for screw thread automatic detection.The utility model adapts to automatic field to screw thread
The logical demand only integrally advised of detection reduces the logical use cost only integrally advised of screw thread.
The utility model to achieve the goals above, adopts the following technical scheme that
A kind of logical only one detection rule of internal screw thread, it includes five parts: grip shank, no-go gage, intermediate guide post, drift and front end
Guide post；
Part design between the drift and no-go gage of detection rule has intermediate guide post；
The front end of drift is provided with front end guide post；
The direction and position for guaranteeing detection rule axis when detecting and switch to no-go gage after drift detection terminates, guarantee and tested
The lesser deviation of screw thread axially bored line is surveyed, no-go gage detection smoothly is carried out to screw thread.No-go gage is examined so as to avoid due to misalignment of axe
It is influenced caused by survey.
Further, it is provided with chamfering on the guide post of front end, in detection rule axis and when detected threaded hole axis runout pair
Detection rule are adjusted, and guarantee that drift smoothly screws in threaded interior and detects to screw thread, so that drift is easy and threaded hole pair
Standard reduces positioning requirements and reduces deviations influence caused by detection simultaneously.
Further, the logical only one detection rule of screw thread are mounted on the automatic thread detection device end with floating clamp,
It is connect by grip shank with detection device.
The utility model has the beneficial effects that
The logical only one detection rule standardization of screw thread is formed standardized product, it is logical can to substantially reduce screw thread by the utility model
The price of no-go gage, while detecting rule and belonging to consumables in the presence of abrasion in the detection process, a large amount of detection work needs detection rule
Asking also will increase, therefore standardizing screw thread to lead to only one detection rule will be that convenience will be brought in automation thread measurement field, together
When can also save objective expense.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
1 pair of the utility model is described in detail with reference to the accompanying drawing:
A kind of logical only one detection rule of internal screw thread, it includes five parts: grip shank 1, no-go gage 2, intermediate guide post 3,4 and of drift
Front end guide post 5；
Part design between the drift 4 and no-go gage 2 of detection rule has intermediate guide post 3；
The front end of drift 4 is provided with front end guide post 5；
Guarantee that the direction and position of axis, guarantee and quilt are advised in detection when switching after the detection of drift 4 terminates to the detection of no-go gage 2
The lesser deviation of screw thread axially bored line is detected, no-go gage detection smoothly is carried out to screw thread.
Be provided with chamfering on front end guide post 5, detection rule axis and when detected threaded hole axis runout to detection advise into
Row adjustment guarantees that drift smoothly screws in threaded interior and detects to screw thread, so that drift 4 is easy to be aligned with threaded hole, reduces
Positioning requirements reduce deviations influence caused by detection simultaneously.
The logical only one detection rule of screw thread are mounted on the automatic thread detection device end with floating clamp, pass through grip shank
1 connect with detection device.
The specific design feature of the utility model, working principle are as follows:
The logical only one detection rule of screw thread are mounted on the automatic thread detection device end with floating clamp, pass through grip shank
1 connect with detection device, drives next side rotation to decline on one side in thread measurement equipment, moves closer to detected threaded hole, first
First contact threaded hole is front end guide post 5, and there is a big chamfering on guide post 5 top in front end, and the conical surface that chamfering is formed advises detection
With guiding role, detection rule can be adjusted in very large range, subsequently enter cylinder guide post part, cylinder guide post will be examined
The axial line control of gauge axis and threaded hole guarantees that drift 4 can smoothly enter into threaded hole and be checked in the deviation range of very little；
With the decline of detection rule, drift 4 starts to contact threaded hole, starts to carry out drift detection to screw thread, in drift detection process
Torsion is monitored, then part is unqualified when torsion reaches preset value, and detection rule reversion exits from, and detection terminates, when torque value does not have
Have and reaches preset value then drift detection part qualification；After drift detection is qualified, detection rule continue to decline, and intermediate guide post 3 starts to connect
Threaded hole, the axial location that intermediate guide post can keep detection to advise are touched, the rotation speed for detecting rule at this time slows down, intermediate guide post 3
Length be necessary for the integral multiple of lead of screw thread, guarantee to detect detection rule screw thread and quilt in no-go gage detection handoff procedure from drift
Screw thread is detected accurately to upper；Last no-go gage 2 detects screw thread, according to screw in thread turns and torque to the detection of no-go gage into
Row judgement, when allowing to reach predetermined torque then part qualification in circle number, if not reaching predetermined torque beyond predetermined amount
Then part is unqualified for value；Finally detection rule reversely rotate, and exit from screw thread, entire detection process terminates.
