Description
(1) technical field:
The present invention relates to measurer, cutlery field, be specifically related to axle diameter instrument.
(2) background technology:
At present generally adopt milscale and slide calliper rule, but owing to be subjected to the restriction of measuring apparatus, precision is difficult to be improved again for the measurement of small axle diameter; Measurement for large-diameter, the normal general measurer of big specification outside micrometer that adopts of prior art, this class axle diameter instrument comprises milscale body, fixedly gauge head, movable gauge head and vernier graduation, in measurement procedure, need two hand steered positive milscales, bob and weave and seek the real diameter of axle, appropriateness screw movable gauge head, to vernier graduation, observation post surveys the diameter of axle value of object.In order to improve the operability of axle diameter instrument, application number is 89202691.X, and name is called the Chinese invention patent of " the direct-reading diameter of axle, sphere diameter gauge ", discloses the measuring instrument of a kind of direct-reading diameter of axle, sphere curvature radius.This measuring instrument mainly is two three location measuring jaws of locating measuring jaw and W shape that adopt V-arrangement on known milscale, and the inverted milscale indicating value that puts in order is formed.When measuring the diameter of axle or sphere curvature radius, inner edge and the measured object of location measuring jaw are tangent, move at micrometric screw and contact measured object when surperficial, and shown in the reading device promptly is the diameter of axle or sphere curvature radius.But the angle that the scale value of milscale need be measured the location between melon and the micrometric screw on this diameter measurement instrument and the sphere diameter gauge determines that through converting this just makes this invent the described diameter of axle, sphere diameter gauge is more complicated when making; And the above-mentioned direct-reading diameter of axle, sphere diameter gauge are to read the diameter of axle that indicating value on fixed muffle and the microdrum obtains testee by the operator, thereby in different measurement number of times different measured values can appear for different operators or same operator, exist certain artificial enchancement factor, be fit to the measurement of small axle diameter, then precision is lower for the measurement of large-diameter.
(3) summary of the invention:
The present invention will disclose that a kind of operability is good, convenient reading, axle diameter instrument that measuring accuracy is high.
Axle diameter instrument of the present invention, it comprises two location legs and chi frame, locatees the V-shaped distribution of leg for described two, and is fixed in the left end of chi frame; Level has a tank on the described chi frame, and this tank runs through the left and right two ends of chi frame, and level is provided with the slip measuring staff in the tank, but this slip measuring staff along continuous straight runs move left and right; Level is provided with and holds the grid assembly on the described chi frame, and the two ends of this appearance grid assembly are individually fixed in the upper/lower terminal of chi frame; Described chi frame is provided with the top that holds the grid assembly and is fixed with a digital conversion display that can calculate and demonstrate the testee diameter of axle according to the amount of movement of the size of the angle that medial surface constituted of location leg and slip measuring staff.
The medial surface of described location leg is a measurement face, and when measuring concrete object, the measurement face on the slip measuring staff is with testee contact, and the medial surface of locating leg also must contact with testee the while; The angle that medial surface constituted of described two location legs is α, and the summit of angle α is positioned on the horizontal central line of chi frame; Described angle is that the big I of α determines that as required it is comparatively suitable to be traditionally arranged to be between 0 ° to 180 °, is preferably greater than to equal 90 ° and less than 180 °.
Under the angle situation that medial surface constituted of determining the location leg, the amount of movement of described slip measuring staff and the diameter of axle of testee are proportional.
Described digital conversion display is to install companion chip IC additional to realize in digital conversion display commonly used; It comprises one can calculate the circuit board and the companion chip IC of the testee diameter of axle according to the amount of movement of the size of the angle that medial surface constituted of location leg and slip measuring staff and can show the testee diameter of axle display screen; According to the size of angle α, calculate the ratio of the amount of movement that holds grid assembly and slip measuring staff, this ratio is called conversion coefficient; Again this conversion coefficient is write in the companion chip IC that installs additional by common method, thereby determined that angle is the conversion coefficient of the axle diameter instrument of α; When actual measurement, the circuit board in the digital conversion display calculates the diameter of axle of testee according to the amount of movement of conversion coefficient and slip measuring staff, demonstrates the diameter of axle of testee again by display screen; As required, also one or more button can be set on the digital conversion display, described these buttons can be on ﹠ off switch, key are set, reset key etc.
When measuring a certain concrete object,, the fixedly locking device of slip measuring staff and digital conversion display relative position can be set also on the top of digital conversion display for the data that the digital conversion display is recorded remain unchanged; Specifically can be an adjusting screw(rod), described adjusting screw(rod) passes digital conversion display and chi frame, is stuck on the slip measuring staff with fixing slip measuring staff, perhaps is other the slip the fixed measuring staff and the parts of digital conversion display relative position.
One end of described slip measuring staff is and the measurement face that is contacted by object that the slip measuring staff has an end of measurement face to be arranged at an end of location leg on the chi frame.
When the actual fabrication axle diameter instrument, described digital conversion display preferably is installed in chi frame and leg connection, location.
The method of operating of axle diameter instrument of the present invention is: at first, select the sizeable axle diameter instrument of two location leg angle α according to the diameter of axle of testee; Calibrate this axle diameter instrument with the smooth cylinder of standard again, it is made zero.The periphery that the medial surfaces of two location legs of axle diameter instrument are stuck in testee makes the surperficial tangent of itself and testee then, level is moved to the left the slip measuring staff simultaneously, the inner edge of locating legs until the measurement face and two of slip measuring staff is simultaneously tangent with the periphery of testee, locking device on this moment stationary digital crossover display terminal, the numerical value on the reading number crossover display terminal display screen is the diameter of axle of testee.
The advantage of axle diameter instrument of the present invention is:
1, axle diameter instrument operability of the present invention is good, volume is little, be easy to carry about with one;
2, need not pass through loaded down with trivial details calculating, directly can read the diameter of axle of testee from the digital conversion display;
3, measuring accuracy height especially is fit to the measurement of large-size axis diameter; When measuring large-size axis diameter, measuring error only is 1/10th of a general axis cable diameter gauge.
