Description
Technical field
The present invention relates to a kind of measuring instrument, especially relate to a kind of spherical outside surface diameter and profile tolerance measuring instrument.
Background technology
In car transmissions, similar ball cage type retainer, bearing with spherical outside surface, oscillating bearing, lasso, steel ball etc. are with the parts that rotatablely move of spherical outside surface structure, the parameters of its sphere sphericity, as diameter, sphere roughness, sphere ripple, spherical shape error etc. have higher shape and size tolerance requirements, it is the important quality index of parts, it is detected and there is no all the time very good method, be the bottleneck of such production quality control and the difficult point of detection, perplexing all the time the check work of this series products.The detection method of existing this type component is the spherical outside surface diameter dimension with the tested parts of spherical outside surface by the outside micrometer check.This method has following weak point: when (1) outside micrometer is measured, be at 2 with the spherical outside surface of tested part and contact, the size that indicating value shows is only the distance of this point-to-point transmission, does not have a generality; (2) 2 of contacting with the workpiece spherical outside surface of milscale gauge head may not be the centers by this sphere, so measuring error is very large; (3) because just measuring two optional points, the reproducibility error of surface measurement is very large; (4) this ectosphere profile tolerance of a surface can't detect.(5) the each measurement, all will be adjusted, and is affected by human factors very greatly, and is difficult to operation, not only operation inconvenience, and after particularly measuring, changeability is large, and it is low to measure efficiency.In a word, former measuring method exists above-mentioned defect, has become the difficult point of this series products detection and the bottleneck of quality control.
Summary of the invention
The objective of the invention is to provide for the prior art weak point a kind of easy to operate, measure accurately, spherical outside surface diameter and profile tolerance measuring instrument that efficiency is high.
The objective of the invention is to realize by following measures: a kind of spherical outside surface diameter and profile tolerance measuring instrument, include clock gauge, it is characterized in that also having base, column and setting nut, sliding sleeve and slide bushing assembly, horizontal dial framework and level frame assembly, some location ball-and-socket, described base is provided with for the groove that the location ball-and-socket is installed, the screw hole seat of column is installed, described column and setting nut form one group of screw pair, described sliding sleeve is provided with for column, the vertical through hole each other that horizontal dial framework inserts, slide bushing assembly is the tightening knob of tightening horizontal dial framework, the locking knob of locking sliding sleeve, described horizontal dial framework is shaft-like, its end is provided with the gauge stand inserted for clock gauge, described level frame assembly is the clock gauge fixed knob, described location ball-and-socket upper surface is provided with the segment sphere with sphere same diameter to be measured, lower surface is provided with the shaft shoulder corresponding with base groove, described some location ball-and-socket, column are fixed by screws on base, setting nut is screwed on column, sliding sleeve is enclosed within the column outer cylinder and rests on setting nut, is fixed on column by locking knob, horizontal dial framework inserts in sliding sleeve, is fixed on sliding sleeve by tightening knob, and clock gauge is arranged in the gauge stand of horizontal dial framework, by fixed knob, clamps clock gauge.
Compared with prior art, the spherical outside surface diameter and the profile tolerance measuring instrument that have adopted the present invention to propose, there is following advantage: the ball-and-socket of 1) according to ectosphere spherical diameter to be measured, making the segment sphere that contains accordingly this diameter, workpiece for measurement is put into to ball-and-socket, adjusting the clock gauge contact touches mutually with workpiece, arbitrarily rotate measured workpiece, can detect its diameter and sphere jerk value; 2) make the ball-and-socket of different size according to actual needs, to adapt to the detection of different workpieces.Novel structure of the present invention, easy to use, measure accurately, reliable and stable, can be widely used in the check of the on-the-spot bulk article in all evaluations with the spherical outside surface parts and workshop.
