Description
Affiliated technical field
The utility model relates to a kind of electronic measuring instrument, a kind of grating displacement measuring device.
Background technology
The volume grate electronic digital display technology with its have the precision height, low in energy consumption, reading is directly perceived, multi-functional, data are output to plurality of advantages such as Computer Processing, has obtained very fast development, the scope of application is more and more wider.On the displacement measurement of many coordinates, the digital display scale and the machine tool digital display unit that utilize capacitive displacement transducer to make, its specification has been accomplished more than 2000 millimeters, and the quantity below 2000 millimeters is in the majority, but on the error of indication detects, also do not have desirable detecting instrument equipment, influenced production and product export.
Summary of the invention
In order to overcome above existing problems, the utility model provides a kind of appliance special for detecting that the pattern displacement principle is measured the capacitive grid numeral display product of using: grating displacement measuring device.
The technical scheme that the utility model adopted is; Interface circuit respectively with computer, the grating chi is connected with tested digital display scale or machine tool digital display unit, AC converter, power switch is fixed in the left front end of threading machine lathe bed side by side, AC converter is connected with reversing switch with motor with lead respectively, power switch is connected with reversing switch with three-phase supply respectively with lead, planker is connected with wire rod thread, be slidingly connected with threading machine bed ways face, left support abutment, right support abutment respectively with cramp frame be fixed on threading machine lathe bed rear rail face about the end, support is screwed the middle part at threading machine lathe bed rear rail face, the grating chi places left support abutment, on right support abutment and the support, and be screwed respectively, protective cover is fixed on the high order end of threading machine lathe bed, motor is connected with gear with the left end of screw mandrel, left side erecting frame is connected with planker with socket head cap screw, and web joint one end is connected with the grating moving grid, and the other end is connected with planker, right erecting frame is connected with tailstock with socket head cap screw, and tailstock is fixed on the low order end of threading machine bed ways face.
After adopting such scheme, make the measurement range of grating displacement measuring device reach the 0-2000 millimeter, not only digital display scale and machine tool digital display unit can be measured, the error of indication of the groove sum of errors of 0-2000 millimeter vernier caliper can also be measured greater than 30 millimeters digital display indicating gauge.It carries out omnidistance positive and negative stroke measurment by the once sampling that whenever keeps at a certain distance away, and shows and prints the measured error of indication and graph of errors.Measuring error is less than 1/5th of capacitive grid type digital display scale and machine tool digital display unit permissible error.Be applicable to the measurement of digital display scale, machine tool digital display unit, vernier caliper and the wide range digital display indicating gauge error of indication.
