Description

Internal diameter lever indicator corrector
Technical field
The utility model relates to a kind of ultra-large type percentage lever meter corrector for boring machine centering cylindrical or endoporus; One is used for part ultra-large type endoporus specifically, a kind of fine adjustment instrument of cylindrical.
Background technology
Prior art dial gauge, by the induction point of radial gauge outfit contact part bore area, carrys out centering at inner bore of part surface sliding.The use indicating type measurer of dial gauge is the measurer indicating measurement result with pointer.Conventional indicating type measurer has: dial gauge, clock gauge, lever indicator and dial bore gage etc.Be mainly used in the installation site correcting part, the form accuracy of inspection part and mutual positional precision, and measure the internal diameter etc. of part.Dial gauge is the general dimensional measuring instrument of tabular form utilizing accurate rack and pinion mechanism to make.Usually be made up of gauge head, gauge rod, antirattle spring, tooth bar, gear, hairspring, round dial and pointer etc.Dial gauge is that the B.C. Ames of the U.S. was made in 1890.Be usually used in the linear measure longimetry of Geometrical Error and thin tail sheep.The round dial of dial gauge is printed with 100 evenly divideds, each scale division value is equivalent to gauge rod and moves 0.01 millimeter.If be printed with 200 or 100 evenly divideds on round dial, then each scale division value is 0.001 millimeter or 0.002 millimeter, and namely this survey instrument is called clock gauge.Change gauge head shape and be equipped with corresponding support, making the distortion kind of dial gauge, as thickness dial gauge, degree of depth dial gauge and dial bore gage etc.As replaced tooth bar to can be made into lever indicator and dial test indicator with lever, its scale range is less, but sensitivity is higher.In addition, their gauge head can rotate in certain angle, can adapt to the measurement of different directions, compact conformation.They are applicable to the Geometrical Error measuring cylindrical, aperture and groove etc. that common dial gauge is difficult to measure.Existing dial gauge great majority are all very little, and the scope of use has limitation, can not meet the alignment technique requirement to super large cylindrical or endoporus before part processing.Gauge outfit all links together with table bar, is nearly all move gauge outfit to operate when dial gauge regulates, and clock gauge or dial gauge sounding rod must be vertical with measured workpiece surface, otherwise can produce error.Sounding rod poor rigidity, quick abrasion, has gone bad depot repair difficulty, has almost scrapped.
Dial bore gage is the combination of interior amount lever measurement bay and dial gauge, in order to measure or the inspection endoporus of part, deep hole diameter and form accuracy thereof.Dial bore gage measurement bay is filled with movable measuring head in one end of three-way pipe, and the other end is filled with interchangeable measuring head, and dial gauge is equipped with by connecting rod 4 in vertical mouth of pipe one end.The movement of movable gauge head makes transmission levers turn round, and is promoted the sounding rod of dial gauge by motion bar, makes dial gauge pointer produce revolution.Because the contact, both sides of lever is equidistant, when movable gauge head moves 1mm, motion bar also moves 1mm, promotes dial gauge cursor backward one and encloses.So the amount of movement of movable gauge head, can read out on dial gauge.Two contact measurers, when measuring internal diameter, are not easy the diametric(al) of alignment holes, and bridge is protected in centering and spring just plays the effect that helps centering diametrical position, makes two measuring heads of dial bore gage just in time at the two ends of diameter of bore.The measurement pressure of movable gauge head is controlled by the spring on motion bar, ensures to measure pressure consistent.The amount of movement of the movable gauge head of dial bore gage, undersized only have 0 ~ 1mm, and large-sized have 0 ~ 3mm, and its measurement range is reached by the length changing or adjust test probe replaceable.Therefore, each dial bore gage is with complete test probe replaceable.The reading value of domestic dial bore gage is 0.01mm, and measurement range has 10 ~ 18; 18 ~ 35; 35 ~ 50; 50 ~ 100; 100 ~ 160mm; 160 ~ 250; 250 ~ 450.The test probe replaceable of large scale dial bore gage, screws on screw thread, therefore the distance that adjustable is stretched out, and undersizedly can not adjust.The error of indication of dial bore gage is larger, and if measurement range is 35 ~ 50mm, the error of indication is ± 0.015mm.Often with special ring gauge or Centigrade scale being proofreaded size (traditionally claim check and correction zero-bit), sometimes also to proofread zero-bit by the clamping slip gauge group of slip gauge annex, and increasing pendulous frequency, could measuring accuracy be improved.During measurement, connecting rod center line will with workpiece centre line parallel, must not be crooked, several point should be surveyed circumferentially more simultaneously, find out the physical size in aperture, see whether within margin tolerance.
Utility model content
The purpose of this utility model is for above-mentioned prior art Problems existing, and provide a kind of centering scope large, centering endoporus is flexible, the internal diameter lever indicator corrector of smooth operation.
The utility model solves the technical scheme that its technical matters adopts, a kind of internal diameter lever indicator corrector, there is the general Morse taper shank of a connecting machine tool main shaft and supporting dial bore gage, it is characterized in that: Morse taper shank 1 axle head is shaped with dovetail slideway 13, stiff end is with the fork ear slide block 4 of dovetail groove, be slidably connected by described dovetail slideway 13, fixed by the dog screw of dovetail slideway 13 radial symmetry, in the fork ear groove of described fork ear slide block 4, be fixedly connected with active lever gauge head 6, active lever gauge head 6 is movably connected in fork ear groove by ear slide block 4 end to the rotating shaft screw bolt 5 connected, and with rotating shaft screw bolt 5 for fulcrum, distance from fulcrum to measurement rod end gauge head is power arm, and active lever gauge head 6 tail end is shaped with elbow.
The utility model has following beneficial effect compared to prior art.
The utility model adopts and connect firmly active lever gauge head 6 in the fork ear groove of fork ear slide block 4, active lever gauge head 6 passes through ear slide block 4 end to connection rotating shaft bolt 5, with rotating shaft screw bolt 5 for fulcrum, distance from fulcrum to measurement rod end gauge head is power arm, directly laterally can be horizontally slipped by dovetail groove, greatly widen the centering correcting range of centering dial gauge; On boring machine, centering endoporus is flexible, smooth operation.It is more steady for being slided by swallow-tail device, and the precision positioning effect of dovetail groove eliminates rocking of dial gauge indicator generation, and manufacturing cost is also very low.Structure is simple, good rigidly, and installation and maintenance are all very convenient, rapid operation, and correct use to the centering of superhuge endoporus or cylindrical, have larger centering scope, maximum centering scope can at 400 ~ 450mm, and minimum hole can at about 15mm.The error of indication that the utility model solves prior art dial bore gage is large, and centering scope is little, is not easy the diametric(al) of alignment holes, auxiliary accessory and the many problem of complete test probe replaceable thereof.
