Description
Technical field
The present invention relates to thread detecting device, particularly relate to a kind of digital display accuracy of thread detection device.
Background technology
During the detection to accuracy of screw machining, current domestic main use high-precision screw thread limit ring gauge and spiral shell
Screw plug ga measures.The gauge that detection external screw thread uses is a pair tapped limit thread ring gauge, and one is called ring gauge
One advised by be made stop ring, and logical ring gauge detects the externally threaded upper limit, and stop ring rule detect externally threaded lower limit, and tested external screw thread can screw in logical
Ring gauge and can not screw in stop ring rule be qualified.The gauge that detection female thread uses is a pair externally threaded internal limit gage of band, one
Individual one, the feeler gauge that is called makes detent plug advise, and logical feeler gauge detects externally threaded lower limit, and detent plug rule detect the externally threaded upper limit, logical feeler gauge energy
Screw in and detent plug rule can not to screw in female thread be qualified.It is primarily present following by the method for screw thread difference gauge detection accuracy of thread
Four problems:
1, logical feeler gauge or logical ring gauge need whole length of tested screw thread by the most qualified, say, that screw thread has how many button,
Being accomplished by manually twisting how many circle, especially in the case of screw buckle is many, efficiency is the lowest；
2, screw thread is under limit state, needs certain moment of torsion to pass through, and operator's labor intensity of inspection screw thread is the biggest；
3, tested part screw thread must be screwed in due to drift, so drift serious wear, need periodic detection and replacing；
4, screw thread ellipticalness cannot detect.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of avoiding and measures the abrasion that full button rotation brings, joint in the past
Saving the measurement time, improve efficiency, greatly reduce labor intensity, half-twist can detect the ovality of tested screw thread, disposably detects
I.e. can determine whether that whether qualified screw thread is, it is to avoid the digital display accuracy of thread detection device logical, only twice operation in the past measured.
The technical scheme is that
A kind of digital display accuracy of thread detection device, leads to ring gauge including horizontal table, displacement transducer, detection display screen, screw thread
Or screw thread leads to feeler gauge.Described screw thread leads to ring gauge (commercially available prod) as external screw thread accuracy detection use, screw thread leads to ring gauge along it
Axis is cut open becomes four pieces, and every piece is not more than 1/4th, selects symmetrical two pieces therein, be set to fix 1/ by one piece therein
4 screw threads lead to ring gauge, and another block is set to mobile 1/4 screw thread and leads to ring gauge, and described 1/4 screw thread of fixing leads to ring gauge and is fixed on horizontal table
On, described movement 1/4 screw thread leads to ring gauge and is fixed on metal block, and metal block is arranged on the slideway set by horizontal table
In, metal block drives mobile 1/4 screw thread to lead to ring gauge and moves along slideway, when metal block moves, it is ensured that mobile 1/4 screw thread leads to
Ring gauge and fix 1/4 screw thread and lead to ring gauge and all can be close on tested external screw thread.Institute's displacement sensors is contained in mobile 1/4 screw thread and leads to
On ring gauge, displacement transducer connects detection display screen by signal transmssion line, is passed by mechanical displacement sensor or pattern displacement
Sensor or capacitive displacement transducer etc. process, and read diameter of thread numerical value, it may be judged whether qualified, are rotated further by 90 ° of tested screw thread, so
Rear reading diameter of thread numerical value judges that the diameter of thread is the most qualified, constitutes digital display external screw thread accuracy detecting device.Described screw thread leads to
Screw thread, as female thread accuracy detection use, is led to feeler gauge and cuts open along its axis and become four pieces by feeler gauge (commercially available prod) equally, selects
Symmetrical two pieces therein, being set to fix 1/4 screw thread by one piece therein and lead to feeler gauge, another block is set to mobile 1/4 screw thread and leads to feeler gauge,
Fixing 1/4 screw thread to lead to feeler gauge and be fixed on horizontal table, mobile 1/4 screw thread leads to feeler gauge by metal block along horizontal table
Slideway move, constitute female thread accuracy detecting device, measure process consistent with external screw thread.
The present invention uses holotype contact measurement, only needs half-twist can complete to measure, it is to avoid former measurement is entirely detained rotation and brought
Abrasion；Save the measurement time, improve efficiency；Owing to being contact measurement, greatly reduce labor intensity；Half-twist can detect quilt
Survey the ovality of screw thread；Disposable detection i.e. can determine whether that whether qualified screw thread is, it is to avoid logical, only twice operation of former measurement.
