Description

Slide block rolling way measuring device and method of work thereof
Technical field
The present invention relates to a kind of slide block rolling way measuring device and method of work thereof, this slide block rolling way measuring device directly can measure slide block raceway position size, can carry out Quick Measurement and the ball selecting size suitable at the assembling scene of slide block and guide rail.Slide block rolling way measuring device install, easy to use, the indirect inspection of the front-slider raceway position size that can substitute.
Background technology
Slide block raceway be slide block when slide on rails and the position of ball engagement, slide block by ball at slide on rails.The precision of slide block raceway position size and the ball the selected overall performance index whether after appropriate relation to slide block and track combination.Therefore the position dimension measuring slide block raceway is necessary step in slide block and set of rails process of assembling.Because the shape of slide block raceway is special, general survey instrument directly cannot measure the position dimension of slide block raceway.
Existing measuring method is mainly divided into two kinds, first method is the geometric position size adopting general survey instrument indirect inspection and calculate slide block raceway position, this result is that error is large, the ball of the standard-sized guide rail of final dependence and sizes carrys out trial assembly, judges adaptive ball with this.This process only focuses on the situation after assembling, and really has its practicality.But with regard to the quality control of production scene, tool bears the character of much blindness.The slide block according to said method assembled, ball and guide rail only meet syntagmatic seemingly, and have no way of understanding and judging to the overall processing quality of four raceways and each raceway engagement situation after combining, the quality control of this project of opinion of more rectifying production scene.Second method is the position dimension adopting three-coordinates measuring machine accurately to measure each raceway in slide block.Although the method is measured accurately, because three-coordinates measuring machine detection is numerous and diverse, efficiency is low, is not suitable for producing in enormous quantities, be unfavorable for that the production cost of enterprise controls.For the bulk article got off from production line, measuring process wastes time and energy and can not reflect that actual that this raceway and ball, guide rail assemble engages situation accurate and visually, repeatedly trial assembly is still needed during assembled in situ, slow down the assembling speed of slide block, ball and guide rail, reduce the production efficiency of enterprise.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of installation and uses all more convenient, directly can to measure slide block raceway position size slide block rolling way measuring device and method of work thereof.
For solving the problems of the technologies described above, the invention provides a kind of slide block rolling way measuring device, it comprises: the measurement mechanism body 1 of rectangular parallelepiped hollow type, its both ends of the surface is respectively provided with a through hole 8; Measurement mechanism body 1 is for being placed in the slide block 5 of measured concave shape; Tapered rods 4, penetrates measurement mechanism body 1 from described through hole 8; Two symmetrical movable blocks 2, be located in measurement mechanism body 1, the medial surface of each movable block 2 is respectively equipped with groove, the medial surface of this groove is inclined-plane 6, and the outside of each movable block 2 is provided with two parallel arc-shaped slots 9; Four length bars 3, for being placed in respectively between arc-shaped slot 9 on movable block 2 and described circular arc raceway 7.
As preferred embodiment, the afterbody of the contiguous described measurement mechanism body 1 in one end that the slot opening of described movable block 2 is larger is arranged.
As further preferred embodiment, the lateral surface relative with described inclined-plane 6 of each movable block is provided with elastic component, is convenient to the convergent-divergent of movable block.
The method of work of described slide block rolling way measuring device, is characterized in that comprising the steps:
A, measurement mechanism body 1 is put on slide block 5, four length bars 3 is put into the correspondence position between the arc-shaped slot 9 on slide block raceway 7 and movable block 2;
B, tapered rods 4 is inserted described through hole 8 from the afterbody of measurement mechanism body 1, and be inserted between two movable blocks 2, and two movable blocks 2 are moved respectively to outside, and compress four length bars 3 gradually, four length bars 3 and slide block raceway 7 are seated;
C, measure each length bar 3 exposed junction between relative dimensions, and to draw: the distance C between the distance B of the symmetrical center line of raceway up and down of slide block and the distance A of slide block 5 bottom surface, right side track centre line and slide block 5 right flank and left and right track centre line.
Relative to prior art, the technique effect that the application has:
(1) adopt the cylindrical length bar consistent with ball normal diameter, accurately can measure the size of slide block raceway position.Because length bar is longer, so only slide block need be disassembled, and use conventional survey instrument just can Quick Measurement, do not affect other parts such as guide rail.Strong adaptability, does not affect activity in production.
(2) movable block moved left and right is provided with arc-shaped slot, and length bar can be made to be fixed on measurement mechanism body by normal place.Tapered rods coordinates can lock movable block with the medial slope of movable block, makes the circular arc raceway close contact of length bar and slide block, and preventing length bar in measuring process from loosening affects measuring accuracy.Measurement mechanism body forms with the materials processing of actual guide rail, the size and shape of key position is identical with guide rail, the material of length bar is consistent with the material of actual ball, makes measuring process can assembly relation truly between analog slider, guide rail, ball, improves measuring accuracy.
(3) measurement mechanism in the present invention, by the measurement exposing looking somebody up and down rod, can draw the relevant physical size A of slide block raceway position, B, C, also according to the degree of tightness situation of four length bars 3, can judge the geometric position situation of four raceways.This measuring process only needs general survey instrument, as electronic digital indicator etc.Measurement is simple, convenient, precision is high, directly can select the ball matched with slide block, guide rail, improve the production efficiency of enterprise without the need to trial assembly.
