Abstract
The invention discloses an inner and outer diameter measuring tool of large-scale working pieces which comprises a scale holder, a wreathed column and a ruler line that is marked on the wreathed column, two ends of the scale holder have hard alloy taper angles, the wreathed column is arranged on an axle line of the scale holder, a subuliform hard alloy is arranged on a telescopic column head of the wreathed column, and reading numbers of the composite ruler line that is carved on a column sleeve of the wreathed column and on the wreathed column are diameter parameters of a circle that is correspondingly determined by three points including the two taper angles of the scale holder and a tip end of the telescopic column head. When the taper angles at two ends of the scale holder are positioned on the surface of a measured work piece, distance from the tip end of telescopic column head to the scale holder is related with diameter value of the circle, which can be read from the ruler line on the wreathed column. The inner and outer diameter measuring tool of large-scale working pieces has the advantages of small volume and convenient measurement.
Description
Technical field
The present invention relates to measurer, particularly a kind of measurer that is used for the part inside and outside diameter measurement.
Background technology
At present, the internal diameter of measuring workpieces or external diameter, generally with slide calliper rule or milscale, large-scale workpiece generally can only be used slide calliper rule.Because workpiece is big, just need large-scale slide calliper rule, need sometimes during measurement to climb on the workpiece, perhaps on the processing equipment such as lathe, also need two people to operate together sometimes.Not only the measurer volume is big for existing method, and measures trouble.
Summary of the invention
It is a kind of as long as measure at the local location of workpiece that the object of the invention is to provide, and just can record internal diameter or external diameter gets measurer, with convenient use.
The solution of the present invention is: a kind of inside and outside diameter measuring tool of large-scale workpiece, comprise chi frame and borded pile, and be engraved in scale line on the borded pile, it is characterized in that: the chi frame is a fork-shaped, the wedge angle of wimet is equipped with at two ends, on the axis of chi frame, borded pile is housed, the column sleeve of borded pile is vertically fixed on the chi frame, the telescopic mast of borded pile, the wedge angle of chi frame points to equidirectional, the telescopic mast head is equipped with the wimet of taper, on the end positions of chi frame magnet is housed, and is engraved in the column sleeve of borded pile and the combined type scale line reading on the borded pile and is two wedge angles of chi frame and the corresponding diameter of a circle parameter at most advanced and sophisticated these three the some places of telescopic mast head.
Advantage of the present invention is: according to mathematical principle, in circle, the string of regular length is to the distance of the mid point of corresponding arc, and is relevant with the diameter of a circle size.The wedge angle at this device chi frame two ends be placed on when surveying surface of the work, this distance of 2 is exactly a chord length, and the most advanced and sophisticated distance to the chi frame of telescopic mast head is promptly relevant with the diameter of a circle size according to above-mentioned principle, can read diameter of a circle by the scale line on the borded pile.The present invention have volume little, measure advantage easily.
Description of drawings
The invention will be further described with embodiment with reference to the accompanying drawings below.
Fig. 1 is a structural representation of measuring the internal diameter device.
Fig. 2 is a structural representation of measuring the external diameter device.
Fig. 3 is the geometric description figure that is used to illustrate measuring principle.
In the drawings: 1 workpiece, 2 chi framves, the column sleeve of 3 borded piles, 4 borded piles, 5 magnet, the wedge angle of 6 chi framves, 7 locks, the telescopic mast of 8 borded piles, 9 telescopic mast heads.
Embodiment
Referring to Fig. 3, in circle, △ ceb and △ cbd are two similar triangles, and its proof procedure no longer calculates.
Thereby, ce/cb=cb/cd
Draw: ce=cb
2/ cd=(cd
2+ db
2)/cd
According to The above results, diameter ce is relevant to the distance (cd) of the mid point of corresponding arc with chord length (2db) and string, if chord length is fixed, then the length of cd just can reflect the diameter of a circle size.
Referring to Fig. 1, the chi frame 2 of embodiment is a fork-shaped, and the wedge angle 6 of wimet is equipped with at the two ends of fork, on the axis of chi frame 2, borded pile 4 is housed.
The column sleeve 3 of borded pile is vertically fixed on the chi frame 2, and the telescopic mast 8 of borded pile, the wedge angle of chi frame 6 point to equidirectional, and telescopic mast head 9 is equipped with the wimet of taper.
The reading that is engraved in the combined type scale line on borded pile column sleeve 3 and the borded pile 4 is two wedge angles of chi frame and the corresponding diameter of a circle parameter at most advanced and sophisticated these three the some places of telescopic mast head, and the marking mode of this scale line is identical with milscale.
Be placed on the surface of workpiece 1 when chi frame 2, magnet 5 attracts workpiece 1 fixing (if right and wrong ironworker part, then place and pin and fix) with hand, distance between the wedge angle 6 of chi frame is the chord length of this section circular arc at this moment, rotate borded pile 4, make tip 9 top tight workpieces 1 of its telescopic mast, read the scale line that is engraved on the borded pile 4 and be inner diameter of workpiece, the mode of reading is identical with milscale.
Shown in Figure 2 is the instrument of measuring external diameter, and structure is identical with the measurement internal diameter, just the length difference of the fork pin of fork-shaped chi frame.Principle is no longer repeated.
