Description

The device for fast detecting of inner bore chamfering depth
Technical field
The inner bore chamfering cubing that the utility model relates to a kind of to detect workpiece perforation depth of chamfering, specifically one Kind detects the chamfer detecting device of mechanical in-process gaging inner bore chamfering depth 0.0mm~5.0mm.
Background technique
Chamfering is the most common manufacturing procedure in machining, and the operations such as vehicle, boring, mill, milling, brill can be completed down The processing at angle.The effect of chamfering mainly has installation to be oriented to, and convenient for assembly, reduces stress and concentrates, prevention is collided with, prevented plowing from, and protects Protect working face;And remove wedge angle, burr, aesthetic appeal.Next is that by the convenience and leakproofness of Fast Installation positioning, With the use stress etc. for reducing fit on, in mechanical processing industry, the chamfering in hole is seen everywhere, is processed in interior bore ends Chamfering is generally existing in all kinds of machine components out.Chamfering majority is processed for technologic needs, is not directly related to generally The quality of part and product, therefore less depth of chamfering t is detected.But for certain more important applications, especially In mass production, the detection of the regulation frequency will be implemented to depth of chamfering between process by still defining.Especially driving The stability of guide tube part under mechanism kinematic state plays a crucial role.It therefore must be in strict accordance in process Product drawing controls its size.Quality to ensure components simultaneously, it is necessary to deep to the chamfering of certain work end faces Degree is controlled.For example the depth of chamfering in the biggish hole of various bearing diameters of aerospace is had been widely used for, this is one A to seem simple, and actually very some intractable measurement problems, especially needing to find out a kind of can be used for mass-producted work The high efficiency method quickly detected between sequence.It is two circles that inner bore chamfering, which projects, does not judge angle.Different chamferings and angle position The deviation of the variation for the inconsistent chamfered bore variation set can all lead to the difficulty in measurement.Chamfered bore is usually by combination boring cutter Be process, the minute differences of knife amount, on workpiece the end in hole be formed by chamfering may be deep some or shallow, chamfering Depth degree it is not easy to control.As detecting element, general depthometer or dial gauge are selected very according to the tolerance of measured parameter Difficult accurate measurement, chamfering inner hole intersection point cause the variation of depth of chamfering, the measurement error of detection device ' can not be measured.In the past The chamfering template measurer used was not easy measured size center in operation, and the chamfering template measurer used, which can not determine, to be surveyed The specific value taken measurements.For example, when bearing is installed on workpiece, usually by being interference fitted and applying certain coupling mechanism force In Assembly part, and lock bearing and be divided into: first is that wrapping up bearing outer chamfer by parts flanged-edge, another is that bearing outer ring leans on It is formed with a circle V-type in nearly outer circle, force is passed through on one side by outer circle V-type, makes the chamfering of its flange package workpiece, this method It is required that chamfering work piece depth must be strictly controlled in the margin of tolerance.With the fast development of mechanical industry, oscillating bearing is Several big pillar industries of the national economy such as

for installation in order to realize, the variation of low-angle can be adapted to automatically at work, all greatly Amount use oscillating bearing, therefore, it is necessary to quickly, accurately measure inner bore chamfering depth.Due to being operated with general gage measuring It is extremely difficult, very big influence is caused to production efficiency and part quality.In the product produced at present, oral area inner chamfer is equal Angled requirement and chamfering big end size tolerance requirements.Inner chamfer hole is exactly the conical bore that a kind of cone-apex angle is 30 °, 45 ° in fact, Due to circle element of a cone and end face out of plumb, the measurement in big end aperture more, the common measurement sides more difficult than straight hole measurement Method is completely inaccurate, let alone the dimensional accuracy required on drawing.In order to solve the survey of the above inner bore of part depth of chamfering Amount problem, currently used conical bore measurement method have four ball method, fill in gauge block method and inversion method etc., detection is all comparatively laborious, right In axis direction length usually only 1,2mm inner chamfer for be not suitable for, basic detection means is all projector inspection at present Survey chamfering diameter, and a kind of more accurately mode;But which investment is big, and low efficiency, scene can not be detected immediately;It is other Mode substantially estimate, slide calliper rule rough measure, since calliper to measure can not feel relieved so error is very big.So must design Special measuring tool easily and effectively come detect the outside diameter of inner chamfer with support batch production product inspection work.According to certain The inner bore chamfering face size of part detects demand, designs test measuring device easily and effectively, with the side in abundant machining Just efficiently measurement means.
