Background technology
The existing equipment that detects Dragon Lord MA series wheel box slide gear antiratchetting groove is French EDIXIA production, the measuring principle that this equipment adopts is the principle by the laser positioning spotting scaming, produce reflection reception back Computer Processing by laser positioning in the needs sites measured and obtain the result, its weak point one is just can provide the result after need all measuring one time to the antiratchetting groove on all splines, Measuring Time is very long, and measuring a part approximately needs 20 minutes; The 2nd, only be fit to the detection of MA series sliding gear collar antiratchetting groove, and be not suitable for the detection of Dragon Lord BE series sliding gear collar antiratchetting groove; The 3rd, the laser initial point often goes out active, occurs being difficult to repair after this fault.In addition, if allow the said equipment also energy measurement Dragon Lord BE series sliding gear collar need reforming equipment, need 400,000 yuan of improvement expenses Renminbi, cost is too high.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of can be implemented in sliding gear collar antiratchetting groove axial dimension measured material that detect on the general checkout equipment MAHR contourgraph, simple in structure, easy and simple to handle, that the single part Measuring Time is short at above-mentioned weak point.
Technical solution of the present utility model is: a kind of sliding gear collar antiratchetting groove axial dimension measured material is characterized in that: comprise the anchor clamps base plate and be fixed on the measurement flat board that cuboid column, benchmark column and datum strip on this anchor clamps base plate constitute.The benchmark column is provided with datum tooth, and the cuboid column is provided with reference circle crest line piece; Its vertical direction is provided with by the tapering mandrel in cuboid column upper edge, locating ring, and the axle and the part centering unit of tensioner nut formation rise in accurate spline location; The axial line of centering is parallel and perpendicular to two sides of datum strip respectively.The tapering mandrel is provided with the radial location pin that accurate spline is located the axle that rises; Accurate spline is located on the axle that rises and is had test trough vertically and have the tensioner nut; The cuboid column is provided with the chaining pin hole corresponding with this test trough, and the contourgraph chaining pin can pass the measurement part from the chaining pin hole.
The utility model is owing to adopt by anchor clamps base plate, cuboid column, benchmark column, datum strip, reference circle crest line piece, the anchor clamps that axle constitutes rise for tapering mandrel, locating ring, accurate spline location, and on the benchmark column, be provided with datum tooth, have the axial groove that the workpiece spline is exposed on rising by axle in accurate spline location, on the cuboid column, be provided with the chaining pin hole.
On the anchor clamps clamping behind the part, the end face of sliding gear collar contacts with the end face of locating ring, whole then when being placed on the contourgraph surveying work table top, two sides of the datum strip on the anchor clamps base plate are close to respectively on two benchmark of work top, chaining pin is placed on the reference circle crest line, because the top of chaining pin is a circular shape, so adjustment profile instrument directions X vernier adjustment knob, demonstration by sensor makes the height point of chaining pin circular arc aim at crest line, because the position correspondence of crest line is the position of sliding gear collar reference circle, so what chaining pin was corresponding now is exactly the position of part reference circle, chaining pin moves down into the chaining pin hole along the Z direction then, pass from the chaining pin hole, obtain the outline line of side of spline tooth and datum tooth by the chaining pin axial scan, can obtain the distance of the outer end points of antiratchetting groove to datum tooth by measuring, again since datum tooth fix to the distance of locating anchor ring, thereby can obtain the distance of the outer end points of antiratchetting groove to locating surface, this is to detect needed axial dimension.After part unclamped, the other one side of something that rotates to anchor clamps was measured again, just can obtain the outline line of this another side of tooth.The BE slide teeth is with three kinds, be respectively 1/2 grade, 3/4 grade, 5 grades sliding gear collars, part shape is different with size, but they also have something in common be exactly their female spline part all be the same, the excircle dimension of location end face all is the same, therefore, these three kinds can realize detecting on these anchor clamps.
The utlity model has following characteristics:
1, this sleeve clamp has only spent 5000 yuans on manufacturing expense, has saved a large amount of expenses with respect to transforming EDIXIA;
2, the anchor clamps maintenance cost is cheap, and maintenanceability is good;
3, measure beat and shortened half;
4, these anchor clamps it is also conceivable that and are applied on the Dragon Lord MA series sliding gear collar, thereby save the measurement cost of MA, also can consider to be applied to outline line dimensional measurement, the especially measurement of endoporus labyrinth of other band qualificationss simultaneously;
5, measurement result can be quantized, be convenient to on-the-spot adjustment equipment.
The utility model is mainly used in and adopts contourgraph to measure the anchor clamps of BE series wheel box sliding gear collar antiratchetting groove axial dimension.
