Description
The utility model relates to length measuring instrument, particularly uses the measuring instrument in footpath in the comparative method for measuring internal thread.
The not-go-end plug thread gauge is adopted in the check in footpath during existing internal thread is single.The check and correction plug thread gauge is adopted in the check in footpath during existing ring thread gage is single.Because the screw thread specification is many, accuracy class is many, the specification grade of required not-go-end plug thread gauge and ring thread gage is many, and therefore the specification and the grade of required check and correction plug thread gauge are also extremely many.Also there is the horizontal length measuring machine of employing hook-type spheric probe to detect, because little, the calculation of complex of sphere diameter rapid wear, measurement range of spheric probe, and fail to be extensive use of.
Given this, the purpose of this utility model just is to provide footpath comparator in the combined type internal thread of a kind of internal thread of energy measurement all size, particularly ring thread gage.
Footpath comparator (referring to accompanying drawing) in the combined type internal thread of the present utility model, include framework and on guide rail (11,12), can link with guide rail slidably and its opposite sides has the protruding in plate (13) and recessed analog meter to plate (14) of identical V-arrangement sword (15) and V-shaped groove (16) respectively, main scale (25) is arranged, can link with main scale slidably and its mutually dorsal part have the recessed gauge head (49) that can be respectively matches with above-mentioned V-arrangement sword and V-shaped groove and protruding gauge head (50) two corriages, can with the middle footpath measuring appliance of the contacted amount instrument of at least one corriage (48).
The V-arrangement angle α of above-mentioned V-arrangement sword (15) can equate with the V-arrangement angle β of V-shaped groove (16); Can equal 60 °, be used to measure metric thread; Also can equal 55 °, be used to measure inch screw thread.
The measuring junction of above-mentioned recessed gauge head (49), can be can with the contacted Qian flute profile in ridge peak middle part; The measuring junction of above-mentioned protruding gauge head (50), can be can be contacted cylindrical with ridge paddy middle part.
Above-mentioned protruding to plate (13) or/and recessed between plate (14) and the framework, regulating part (20) can be arranged.
Two above-mentioned corriages, the trip frame (26,31) and the keeper (29,34) thereof that are contained on the main scale (25) can be arranged, be connected with the measuring jaw (30) of bar shaped in one of them trip frame (26), another trip frame (31) with have the location extensible member of the measuring jaw (45) of bar shaped to link, this trip frame (31) and be sleeved on the main scale (25) and have between the little trip frame (51) of keeper regulating part is arranged.
Above-mentioned amount instrument (48), can be contained in that trip frame (31) is gone up and its amount head can with contacted dial gauge of measuring jaw (45) or clock gauge.
Above-mentioned location extensible member, the guide shaft (36) that is connected on the trip frame (31) can be arranged, be sleeved on the guide shaft slidably and sliding sleeve (37) that connects with measuring jaw (45) and push rod (42) thereof, the sliding sleeve positive stop key (38) on the guide shaft, the back-moving spring between guide shaft and sliding sleeve (40).
Above-mentioned regulating part (20,52) can be the threaded adjusting structure.
Above-mentioned regulating part (20) can be the threaded adjusting structure that clasp nut (22) is arranged.
Use the utility model, at first press the middle footpath size of the tested screw thread of issuing standard, the combination gauge block that apolegamy is suitable, its appropriateness is clamped in two of analog meter between the plate, thereby make two to the V-shaped groove of plate and the size between the V-arrangement sword, become the tested thread standard of simulation with specific middle footpath.Secondly, the corriage of footpath measuring appliance in the adjustment, its protruding gauge head and recessed gauge head are put into two among the plate, make it closely to contact with the V-arrangement sword with V-shaped groove respectively, to measure the instrument pointer then and place zero-bit, thereby the tested thread standard of simulation in footpath in specific be transferred between the protruding gauge head and recessed gauge head of middle footpath measuring appliance.During measurement, corresponding Ya Gu and Ya Feng with tested internal thread, ring thread gage, closely contact with recessed gauge head with protruding gauge head respectively, obtain the elementary errors numerical value of 0 of needle deflection from the amount instrument, this elementary errors numerical value and the algebraic sum that makes up gauge block numerical value promptly are tested internal thread, the single middle footpath of ring thread gage.
The utlity model has following advantage.
One, the utility model is transferred to the tested thread standard of simulation of analog meter acquisition on the measuring appliance of middle footpath, tested screw thread is carried out differential measurement, obtain pitch diameter of thread size, be not subjected to the influence of pitch, half of thread angle deviation in the measurement, measuring accuracy height, the actual single middle footpath that can measure screw thread, and be convenient to grasp wear law, to the calibration interval of reasonable formulation ring thread gage, judge that whether it is qualified, can provide tangible data especially.
Two, measurement range of the present utility model is big, can not only measure the single middle footpath of various internal threads, particularly can be used to measure ring thread gage, can replace the check and correction plug thread gauge that a large amount of being used to detects ring thread gage, only at pitch 0.5～6mm, in the screw measurement scope of diameter 18～150mm, originally need the school of 169 kinds of specifications, 9 accuracy classes logical-end plug thread gauge, school logical-decrease that plug thread gauge, school end-end plug thread gauge, plug thread gauge meter 4 classes check and correction external thread gauge is ended-decreases in the school, amount to 6084 kinds of check and correction plug thread gauges, all can be replaced by a playscript with stage directions comparator.Can save wide variety of materials, the energy, manpower, funds.
Three, the utility model adopts the differential method of measurement, and the gauge head wearing and tearing can not influence accuracy of detection.To repairing long service life after plate, the gauge head wearing and tearing.
Four, location of the present utility model extensible member structure can be located measuring jaw, and flexible again is convenient to change detected member, improves measuring speed.
Five, regulating part structure of the present utility model can be adjusted two freely to the distance between the plate, and two distances of swimming between the frame, the convenient adjustment and detection.
Below, the utility model is further described to use embodiment and accompanying drawing thereof again.
