Description
Technical field
The invention belongs to wheel production testing technical field, relate in particular to a kind of calibration equipment of wheel for track mark.
Background technology
It is the position that wheel is mainly measured that wheel rolling circular diameter detects.At present the detection method of wheel rolling circular diameter is had to two kinds: a kind of is to use universal or special vernier caliper measurement wheel rolling circular diameter; The wheel of another kind of Shi Duian U.S. AAR standard production uses mark to measure the girth of wheel rolling circle, show that corresponding mark is number with conversion wheel rolling circle diameter.Its mark binds round shape ringwise by the specially-used measuring instrument of manufacture produced in USA, in wheel is produced, mark frequency of usage is high, need precisely operation, mark is measured after wheel some, must to mark, proofread with supporting ring gauge, existing problems are ring gauges that home market does not have corresponding verification mark to use, need deliver to specially U.S.'s verification, two-way time is long, cost is large, incur loss through delay and use, adopt vernier caliper measurement rolling circle diameter, the result recording is converted and compared with the mark number of mark nominal, because converting, vernier caliper measurement there is error, can not directly check and approve the precision of mark, have a strong impact on the result of determination of wheel, can cause certified products to be sentenced useless, production cost improves, or waste product is judged to the safe handling that certified products affect wheel.
Summary of the invention
The defect existing in order to overcome prior art, the object of this invention is to provide a kind of wheel for track mark calibration equipment, its verification is convenient, fast, timely, eliminates the error that general vernier caliper estimation mark number and manual conversion cause, and precisely verification, guarantees the accuracy that mark detects.
Wheel for track mark calibration equipment, is characterized in that this device is comprised of sample wheel base, support and LED display, and described sample wheel base is rectangular, and two seat supports are at least set on base; Described support is comprised of supporting leg, pallet and core platform, and supporting leg is fixed on base, connecting trays on it, and pallet central authorities establish core platform, sheathed sample wheel on each support; Described LED display is fixedly placed in protects frame, protects frame and is fixed on pillar, is connected with base.During verification, sample wheel is placed on support, display operation explanation in LED display, and reviewer carries out verification according to explanation to mark to be verified.
The present invention further improves, described two seat supports sizes, highly different, and sample wheel that can sheathed two kinds of specifications is to carry out verification to the mark of two kinds of range abilities.
The present invention further improves, the material of described difference wheel is identical with wheel material, press AAR standard machine programming simulation ring gauge design sample wheel shape as calculated, by CAD, the typing that is related to of three fixed support coordinate points of mark and corresponding single axle is calculated to differentiation, to position that can not discriminating measurement, and revise affecting the departure of different curve point position appearance, by machine cut, processed.
The present invention further improves, and described pallet is homogeneous disc, and card is smooth, and its diameter is less than the diameter of sample wheel, is greater than the diameter of wheel bore, and coniform core platform is set on pallet, and its center line is consistent with tray centerline; Core platform bottom surface diameter matches with sample wheel hub bore diameter, and sample wheel is placed on pallet, and wheel bore is enclosed within on core platform, reliable and stable.
The present invention further improves, described supporting leg is positive triangular shape and distributes, height is identical, one end is welded on horizontal base, the other end is connected with tray bottom surface, center and the pallet center of circle of the equilateral triangle that three tie points form coexist on a vertical line, are connected firmly stable, and pallet card keeps horizontality.
The present invention further improves, and described supporting leg is column, and one end is welded on horizontal base, and the other end is connected with tray bottom surface, and the center of column and the pallet center of circle coexist on a vertical line.
During verification, band ruler ferrule is on sample wheel tread, and three fixed supports of mark, must not be gapped near sample wheel tread, two of both hands tension mark, and mark blade is adjacent to sample wheel tread, and mark and sample wheel tread are combined into one, and determine measuring position; With mark, measure the mark number of the rolling circle girth of sample wheel, then mark number is taken turns to the nominal value dispatching from the factory with sample contrast, with the accuracy of verification mark.
Compared with prior art, advantage is novel, simple and reasonable for structure; Use reliably, eliminate the error that general vernier caliper estimation mark number and manual conversion cause, verification is accurate, guarantees the accuracy that mark detects, and while avoiding wheel detection, judges by accident, is conducive to reduce costs and wheel uses safety; Verification is convenient, fast, reduces labour intensity, increases work efficiency.
