Abstract
The invention discloses a method for measuring a small hole diameter by using of a dial indicator. The method includes the following steps: connecting the dial indicator and a conic degree measuring mandrel rod to manufacture a small hole measuring device, and using the conic degree measuring mandrel rod as a measuring bar of the dial indicator; and installing the measuring mandrel rod, checking measuring original points of the dial indicator by using a check gauge, and then measuring the inner diameter of a workpiece. The method for measuring the small hole diameter by using of the dial indicator has the advantages that measurement is simple and convenient and easy to operate, measurement accuracy is high, on-line measurement can be carried out, and work efficiency of batch measurement is greatly improved.
Description
Technical field
The invention belongs to the size measurement technique field, relate to specifically a kind of method of measuring hole diameter with dial gauge.
Background technology
The measurement of general aperture adopts slide calliper rule or micrometer inside caliper to measure, measure inaccurate, human factor is very large on the measurement result impact, measurement for tapered hole is then more inconvenient. and image instrument is adopted in the measurement of modern high precision aperture, the measuring equipment that three coordinates etc. are advanced, but this measurement is difficult to realize the on-line measurement of production.
Summary of the invention
The objective of the invention is for above-mentioned deficiency of the prior art, the method for measuring hole diameter with dial gauge is provided, can carry out on-line measurement to orifice size easily.
The technical solution adopted for the present invention to solve the technical problems is: the method for measuring hole diameter with dial gauge may further comprise the steps:
1) dial gauge is connected with the taper measurement axle makes the aperture measuring device, the taper measurement axle is as the sounding rod of dial gauge;
2) treat size and the accuracy requirement of gaging hole according to workpiece, select applicable check gauge and taper measurement axle;
3) install the measurement axle, use check gauge check and correction dial gauge to measure initial point;
4) press down control lever and be well placed workpiece, make the taper measurement axle slowly insert inner hole of workpiece, the tested end face of workpiece is close to gauge head simultaneously;
5) read registration at dial gauge, the physical size that measuring and calculating is portalled according to taper measurement axle taper ratio.
The concrete structure of measurement mechanism described in the step 1) is: comprise dial gauge, taper measurement axle and frame, described taper measurement axle is the thin tapered rod of the thick end of an end, the butt end of taper measurement axle connects described dial gauge, sounding rod for dial gauge, described erecting is porose, and described taper measurement axle can pass this hole.
For more convenient batch workpiece is measured fast, measurement mechanism also comprises lower gauge head, control lever and spring, described lower gauge head correspondence is arranged on the below in the hole of described frame, there is the hole of passing for described taper measurement axle described lower gauge head upper end, described spring is arranged on described lower gauge head bottom, described control lever and lower gauge head are flexibly connected, the described lower gauge head height of capable of regulating.
For reaching stable accurately measuring accuracy result, preferably by the accurate development of wimet, the range of taper of taper measurement axle is generally between 1:5-1:10 for the taper measurement axle in the measurement mechanism of the present invention.
The method employing comparative method for measuring principle of measuring hole diameter with dial gauge of the present invention, special wimet precise finiss taper measurement axle is docked with dial gauge, Application standard hole check gauge calibration dial gauge is measured numerical value, then workpiece being compared method measures. and adopt the range of taper of tapering alloy axle in the design between 1:5-1:10, size and measuring accuracy according to the hole require to select. owing to adopt tapered hole and measured workpiece to compare measurement, that the dimension difference of workpiece hole and control gauge is amplified in measuring principle, for example: the check gauge that diameter is 2 millimeters, the diameter of measured workpiece is 2.05 millimeters, applicable 1:10 taper measurement axle compares measurement, 0.05 millimeter reading on dial gauge of the internal diameter difference of workpiece and check gauge will be exaggerated ten times, the difference that shows is 0.5 millimeter. because measured value has been carried out effective amplification, thereby realized the high-acruracy survey of aperture port. this measurement is applicable to the measurement to the demanding straight hole of the port sizes in hole and tapered hole. this measure load small and exquisite, be easy to carry and lay, simple operation, measure accurately, can be accurate to 0.001mm, desirable measurement range is 1-5mm.In actual use, can show at the enterprising rower of dial gauge according to the margin tolerance in hole, do not convert and do not need every product all to carry out tapering, improve and measure efficient.
The present invention has following outstanding beneficial effect: measure simple and easy to operately, measuring accuracy is high, can carry out on-line measurement, greatly improved the measurement efficient of measure batch.
