Abstract
The utility model relates to an axle pitch measuring ruler for an arc reference axle and relates to a measuring device of a train axle. With the axle pitch measuring ruler adopted, technical problems of high cost and incapability of accurately measuring actual axle pitches of a measurement tool for measuring the axle pitch of the arc reference axle can be solved. The axle pitch measuring ruler for the arc reference axle is composed of a fixed reference arc, a movable reference arc, a fixed supporting seat, a movable supporting seat, a vernier numerical value reading device and a ruler body; the fixed reference arc and the movable reference arc are consistent with the arc of the neck of the axle; the ruler body is provided with the vernier numerical value reading device; one end of the ruler body is connected with the fixed supporting seat; the fixed supporting seat is connected with the fixed reference arc; the vernier numerical value reading device is connected with the movable supporting seat; and the movable supporting seat is connected with the movable reference arc. The axle pitch measuring ruler of utility model is used for measuring the axle pitch of the arc reference axle and is advantageous in great universality, simple structure, economical property, practicability, accurate and intuitive measurement.
Description
Technical field
The utility model relates to the measurement mechanism of railroad car axle, relates in particular to the distance between axles measurement mechanism of circular arc benchmark axletree.
Background technology
AAR standard axletree is widely used in the areas such as North America, Australia, Southeast Asia.Its axle type feature is that axle journal is that circular arc is connected with dust guard seat place, and axle journal inner side is without straight shoulder, take axle journal circular arc as reference design distance between axles, requires to guarantee distance between axles size in process.
Existing axletree distance between axles dip stick can only be measured the axletree distance between axles that axle journal inner side is straight shoulder, cannot measure the distance between axles of above-mentioned circular arc benchmark axletree.Prior art has two kinds of methods to the measurement of circular arc reference axis spacing: 1, make axle journal length model, carry out coincidence measurement by measuring overall length of axle and axle journal length calculated difference; 2, do special axis pitch measuring tool coincidence measurement.Above-mentioned first method need be made disalignment neck length degree model to different axletrees, and overall length of axle and axle journal length dimension are required to control as strict as possible, has increased axletree processing cost; Second method need to be made disalignment pitch measuring tool for the axletree of disalignment spacing dimension, and making measurer expense is high.Meanwhile, above-mentioned two kinds of measuring methods are accordance and measure, and cannot accurately measure axletree actual axle spacing dimension, and can produce erroneous judgement to distance between axles dimension limit axletree.
Utility model content
The purpose of this utility model is intended to overcome the shortcoming of prior art, a kind of distance between axles dip stick of circular arc benchmark axletree is provided, solve existing circular arc reference axis distance between axles measuring method making measurer expense high, and cannot accurately measure the technical matters of axletree actual axle spacing dimension.
The utility model is to realize by technical scheme below:
A kind of distance between axles dip stick of circular arc benchmark axletree, it is characterized in that: described distance between axles dip stick is made up of fixed reference circular arc, movable benchmark circular arc, hold-down support, movable bearing support, vernier reading device and blade, described fixed reference circular arc is consistent with axle journal circular arc with movable benchmark circular arc, vernier reading device is installed on described blade, the other end at blade is connected and fixed bearing, described hold-down support is connected with fixed reference circular arc again, described vernier reading device is connected with movable bearing support, and described movable bearing support is connected with movable benchmark circular arc again.
The utility model, for the measurement of circular arc benchmark railroad car axle distance between axles, has measurer versatility good, simple in structure, economical and practical, measures accurate advantage directly perceived.
Accompanying drawing explanation
Fig. 1 is structure of the present utility model and the view of measuring circular arc benchmark axletree distance between axles;
Fig. 2 is the side view of Fig. 1.
Embodiment
The utility model is further described by embodiment below in conjunction with accompanying drawing:
As shown in Figure 1, 2, a kind of distance between axles dip stick of circular arc benchmark axletree, formed by fixed reference circular arc 1, movable benchmark circular arc 2, hold-down support 3, movable bearing support 4, vernier reading device 5 and blade 6, described fixed reference circular arc is consistent with axle journal circular arc with movable benchmark circular arc, on described blade 6, vernier reading device 5 is installed, be connected and fixed bearing 3 at the other end of blade 6, described hold-down support 3 is connected with fixed reference circular arc 1 again, described vernier reading device 5 is connected with movable bearing support 4, and described movable bearing support 4 is connected with movable benchmark circular arc 2 again.
When measurement, distance between axles dip stick is placed on axletree 7, fixed reference circular arc 1 is adjacent to axletree 7 one end-journal circular arcs, moving cursor reading device 5 drive activity benchmark circular arcs 2, after movable benchmark circular arc 2 is adjacent to axletree other end axle journal circular arc, read numerical value on moving cursor measurement mechanism, be axletree distance between axles size L.
