Abstract
The utility model discloses a long ruler for measuring a flexible cylinder, disclosing a caliber rule for measurning a cylinder, particularly for measuring the diameter of a cylinder with a shin wall. The long ruler for measuring a flexible cylinder is formed by the combination of a measuring tape and a digital displaying caliber rule or a dial gauge caliber rule. Combined with the diameter of a reference element, the diameter of a measured workpiece can be measured directly. The utility model has the advantages of convenient operation, and high precision.
Description
The utility model relates to a kind of slide calliper rule that right cylinder is particularly measured thin cylinder external diameter or girth of measuring.
The known measurement slide calliper rule that are applicable to the rigid cylindrical body, the clock gauge slide calliper rule that the long wind mechanical of digimatic calipers and the Suzhou factory that produces as Shanghai Measuring and Cutting Tools Plant produces, though than general slide calliper rule bigger improvement is being arranged aspect measuring operation and the measuring accuracy, but still is failing to solve the accurate problems of measurement of flexible thin cylinder.
Existing thin cylinder measurer is π band (claiming to enclose chi again), promptly is adjacent to after measured piece winds with one circuit with a metal tape that is carved with long measure (millimeter or π millimeter), reads the girth or the external diameter of measured piece in its junction.Owing to when measuring, should with the hands strain the π band, use a careful resolution calibration again, the operator is easy to fatigue.Not only use inconvenience, and measuring accuracy can not get also guaranteeing.
The purpose of this utility model be to avoid above-mentioned weak point of the prior art and provide a kind of easy to use, measure accurate slide calliper rule.
The technical solution of the utility model is: form slide calliper rule by measuring tape, preceding fixed block, chi bar, middle cushion block and trip frame, it is characterized in that wherein having a measuring tape and the trip frame that digital display device or clock gauge are housed.
The utlity model has following accompanying drawing:
The stereographic map of Fig. 1 slide calliper rule A example;
The stereographic map of Fig. 2 slide calliper rule B example;
Fig. 3 measuring tape stretch-out view;
Fig. 4 measuring tape installment state figure;
Fig. 5 school small incidental expenses is with reference to part figure.
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
Slide calliper rule are made up of measuring tape 1, preceding fixed block 2, chi bar 3, middle cushion block 4 and trip frame 5.Measuring tape 1 is smooth no scale metal tape, and on the lower plane of preceding fixed block 2, the other end in kind is fixed on the lower plane of trip frame 5 after passing the fenestra of this band the one end, forms a measuring tape circle with tackifier or screw retention.Middle cushion block 4 is fixed on the junction at measuring tape circle two ends when measuring.The trip frame 5 that digital display device or clock gauge are housed can slippage on chi bar 3.Middle cushion block 4, preceding fixed block 2 and trip frame 5 threes' lower plane all at grade and be parallel to the plane of chi bar 3, to guarantee measuring accuracy.Hold slide calliper rule with the right hand during measurement, measured piece be inserted in the measuring tape circle, promote the trip frame when measuring tape is adjacent to measured piece with thumb, can be from digital display screen or the clock gauge pointer read data.Before measuring workpieces, should measure earlier one previously selected with reference to the part size, fixed zero behind the reading, measure measured workpiece again, institute's value is a measured workpiece girth and with reference to the difference of part girth like this.When measured workpiece diameter during less than reference part diameter, its difference be on the occasion of, otherwise be negative value.As to establish difference be Δ 1, is d with reference to the part diameter
0, then the diameter d of measured workpiece is: d=d
0-Δ 1/ π.
Slide calliper rule shown in Figure 1 are measuring tape and the combining of digital display calliper.Reading can be delivered to counter and printer thereof during measurement, input is with reference to the part diameter d earlier
0, measuring workpieces, by formula d=d again
0-Δ 1/ π and relevant procedures directly show or print the diameter of measured workpiece.
Slide calliper rule shown in Figure 2 are measuring tape and the combining of clock gauge slide calliper rule (scale changes the π millimeter into).Survey earlier during measurement, survey workpiece again, can directly read measured workpiece and difference, again d=d by formula with reference to the part diameter with reference to part and zeroing
0-Δ 1/ π draws the diameter of measured workpiece.
The measuring tape width b of these slide calliper rule
1With reference part thickness b
2Size should close (20～25 millimeters).Measured workpiece also should be identical with material with reference to part, to reduce temperature effect, guarantees measuring accuracy.
Claims (3)
1, a kind ofly measures the slide calliper rule that right cylinder is particularly measured flexible thin cylinder, fixed block 2, chi bar 3 and trip frame 5 before comprising, the two ends that it is characterized in that measuring tape 1 are separately fixed at formation one measuring tape circle on preceding fixed block 2 and the trip frame 5, on trip frame 5 digital display device or clock gauge are housed.
2, slide calliper rule as claimed in claim 1 is characterized in that said measuring tape 1 is smooth no scale metallic elastic band.
3, slide calliper rule as claimed in claim 1 or 2, fixed block 2, middle cushion block 4 and trip frame 5 threes' lower plane and is parallel to the plane of chi bar 3 all at grade before it is characterized in that.
