Abstract
The invention discloses the method that hole diameter measured by dial gauge: be connected with taper measurement axle by dial gauge and make aperture measuring device, taper measurement axle is as the sounding rod of dial gauge; Install measurement axle, use check gauge check and correction dial gauge to measure initial point, then workpiece diameter is measured.The work efficiency the invention has the beneficial effects as follows: measure simple and easy to operate, measuring accuracy is high, on-line measurement can carried out, substantially increase measure batch.
Description
Technical field
The invention belongs to size measurement technique field, relate to a kind of method that hole diameter measured by dial gauge specifically.
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 measurement result impact, measurement for tapered hole is then more inconvenient. and the measurement of modern high precision aperture adopts image instrument, the measuring equipment that three coordinates etc. are advanced, but this measurement is difficult to the on-line measurement realizing production.
Summary of the invention
The object of the invention is for above-mentioned deficiency of the prior art, the method measuring hole diameter is provided, on-line measurement can be carried out to orifice size easily with dial gauge.
The technical solution adopted for the present invention to solve the technical problems is: the method measuring hole diameter with dial gauge comprises the following steps:
1) be connected with taper measurement axle by dial gauge and make aperture measuring device, 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 measurement axle, use check gauge check and correction dial gauge to measure initial point;
4) depression bar is well placed workpiece, makes taper measurement axle slowly insert inner hole of workpiece, and the tested end face of workpiece is close to gauge head simultaneously;
5) on dial gauge, read registration, calculate the physical size of portalling according to taper measurement axle taper ratio.
The concrete structure of measurement mechanism described in step 1) is: comprise dial gauge, taper measurement axle and frame, described taper measurement axle is the thin tapered rod in thick one end, one end, the butt end of taper measurement axle connects described dial gauge, for the sounding rod of dial gauge, described erecting is porose, and described taper measurement axle can pass this hole.
In order to 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 passed for described taper measurement axle described lower gauge head upper end, described spring is arranged on described lower gauge head bottom, described control lever is flexibly connected with lower gauge head, lower gauge head height described in adjustable.
For reaching stable measuring accuracy result accurately, the taper measurement axle in measurement mechanism of the present invention is preferably by the development of wimet precision, and the range of taper of taper measurement axle is generally between 1:5-1:10.
The method that hole diameter measured by dial gauge of the present invention adopts comparative method for measuring principle, special wimet precise finiss taper measurement axle is docked with dial gauge, gauge orifice check gauge calibration dial gauge is used to measure numerical value, then compare method to workpiece to measure. design adopt the range of taper of tapering alloy axle between 1:5-1:10, require to select according to the size in hole and measuring accuracy. compare measurement owing to adopting tapered hole and measured workpiece, measuring principle is the dimension difference of workpiece hole and control gauge is amplified, such as: the check gauge that diameter is 2 millimeters, the diameter of measured workpiece is 2.05 millimeters, be suitable for 1:10 taper measurement axle and compare measurement, the reading of internal diameter difference 0.05 millimeter on dial gauge of workpiece and check gauge will be exaggerated ten times, the difference of display is 0.5 millimeter. due to measured value has been carried out effective amplification, thus the high-acruracy survey of aperture port is achieved. this measurement is applicable to require high straight hole and the measurement of tapered hole to the port sizes in hole. it is small and exquisite that this measures loading, be easy to carry and lay, simple operation, measure accurately, 0.001mm can be accurate to, desirable measurement range is 1-5mm.In actual use, according to the margin tolerance in hole, can show at the enterprising rower of dial gauge, and do not need every part product all to carry out tapering conversion, improve and measure efficiency.
The present invention has following outstanding beneficial effect: measure simple and easy to operate, and measuring accuracy is high, the measurement efficiency that can carry out on-line measurement, substantially increase measure batch.
Accompanying drawing explanation
Fig. 1 is that measurement mechanism structural representation in the method for hole diameter measured by dial gauge of the present invention;

As shown in fig. 1, the quick device for accurately measuring dial gauge 1 of aperture as shown in Figure 1, taper measurement axle 3 and frame 2, described taper measurement axle 3 is the thin tapered rod in thick one end, one end, the butt end of taper measurement axle 3 connects described dial gauge 1, as the sounding rod of dial gauge 1, described frame 2 is provided with hole, described taper measurement axle 3 can pass this hole, 4 is workpiece to be measured, described spring 7 is arranged on described lower gauge head 5 bottom, described control lever 6 is flexibly connected with lower gauge head 5, lower gauge head 5 height described in adjustable.
Measuring method comprises the following steps:
1) be connected with taper measurement axle by dial gauge and make aperture measuring device, 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 measurement axle, use check gauge check and correction dial gauge to measure initial point;
4) depression bar is well placed workpiece, makes taper measurement axle slowly insert inner hole of workpiece, and the tested end face of workpiece is close to gauge head simultaneously;
5) on dial gauge, read registration, calculate the physical size of portalling according to taper measurement axle taper ratio.
Be more than preferred embodiment of the present invention, all changes done according to technical solution of the present invention, when the function produced does not exceed the scope of technical solution of the present invention, all belong to protection scope of the present invention.
