Abstract
The invention discloses a device for detecting a depth from a handheld axle hole spigot to a spherical surface, comprising a die sleeve, a spacer, a shell, a mandrel, a spring, an upper cover and a meter, wherein the die sleeve, the shell and the upper cover are sequentially connected into a three-section sleeve; the meter is installed in an axial through hole at the top end of the upper cover; the mandrel is in clearance fit with the three-section sleeve; and the top end of the mandrel is in contact with a meter rod part measuring end. A compression spring is sleeved between the upward end face of the middle section of the mandrel and the inner end face at the top end of the upper cover to form an axial elastic shrinkage structure of the meter rod part measuring end together with the mandrel along with the inner cavity of the die sleeve. The spacer with the thickness of 2-5mm is arranged in the inner cavity of the die sleeve, the overhang of the bottom section of the mandrel is regulated by regulating the thickness of the spacer; the bottom end face of the die sleeve is provided with a spherical cavity which is opposite to and has the same size with the end face of the axle hole spigot of a workpiece. As a handheld structure is adopted, the device for detecting the depth from the handheld axle hole spigot to the spherical surface has the advantages of convenience for operation and high detection efficiency and is convenient to use in a production field.
Description
Technical field
The invention belongs to the cubing of length measuring device technical field, specifically, the present invention relates to a kind of axis hole seam to sphere degree of depth cubing.
Background technology
Many mechanical component orifice parts that are equipped with axle are provided with seam, and generally this seam cooperates the location with the shoulder of supporting axle.Whether this type of part seam depth dimensions the overproof bearing accuracy that is directly connected to the installation site; For axis hole seam end face is the part on plane; Just can accomplish accurate measurement with the commodity micrometric depth gauge; And that axis hole seam end face is the part of curved surface is uncertain because of measuring basis, promptly uses the commodity micrometric depth gauge also to can not get accurate measurement result.For example; Bevel planet gear axis hole seam end face in the automobile gearbox is a spherical, and this seam has the depth dimensions requirement, and the production scene lacks the quantification cubing and instructs production; Only do complementary detection, so seam depth dimensions controlled circumstances is not good with some qualitative cubings.
Summary of the invention
It can not the measures of quantization end face be the deficiency of the axis hole seam degree of depth of curved surface that the present invention is primarily aimed at existing general cubing, propose a kind of simple in structure, makings is easy, easy and simple to handle, accuracy of detection is high and hand held axis hole seam to the sphere degree of depth cubing through quantification indication measurement result.
The present invention realizes technical goal through following technical proposals.
Hand held axis hole seam to sphere degree of depth cubing, it comprises die sleeve, pad, shell, mandrel, spring, loam cake and table tool.Said die sleeve, shell and loam cake are the housing class A of geometric unitA, and the three connects and composes three joint covers from bottom to top successively, and superposed loam cake top is provided with axially extending bore, and the bar portion of table tool inserts and is locked in the loam cake top axial through hole.Said mandrel is that stepped axle places three joint cover inner chambers, at the bottom of the mandrel section and stage casing respectively with die sleeve endoporus and shell endoporus clearance fit, the mandrel top with show tool bar portion measuring junction and contact.Its improvements are: the mandrel stage casing is towards pocketed springs between upper surface and the loam cake top inner face; Under the preloading spring effect, still keep table tool bar portion measuring junction contact with the mandrel top end face, directly formation show tool bar portion measuring junction with mandrel along the die sleeve lumen shaft to the elastic telescopic structure.Be provided with the pad of thick 2.0mm～5.0mm in the said die sleeve inner chamber; Thickness through the transposing pad; Section overhang at the bottom of the adjusting mandrel; Overhang is greater than workpiece axis hole seam vertical depth 0.5mm～1.0mm to be checked, and the die sleeve bottom face is provided with and the opposite but measure-alike sphere cavity of workpiece axis hole seam end face.
In the said structure, the die sleeve bottom sphere cavity degree of depth equals measured workpiece sphere height, and hole dimension is identical with workpiece axis hole seam internal diameter in it.Used spring is a compression spring, and table tool measuring accuracy as requested confirms to select for use dial gauge or clock gauge.
The present invention compared with prior art has following good effect:
1, simple in structure, make easily;
2, quantize to detect, measure accurately;
3, hand held structure, simple operation, detection efficiency is high.
Description of drawings
Fig. 1 is a structural profile synoptic diagram of the present invention.
Embodiment
According to accompanying drawing and combine embodiment, the present invention is described further below.
Hand held axis hole seam to sphere degree of depth cubing shown in Figure 1, it comprises die sleeve 1, pad 2, shell 3, mandrel 4, spring 5, loam cake 6 and table tool 7.Said die sleeve 1, shell 3 and loam cake 6 are the housing class A of geometric unitA; The three connects and composes three joint covers from bottom to top successively; Superposed loam cake 6 tops are provided with axially extending bore, and the bar portion of table tool 7 inserts and is locked in the loam cake 6 top axial through holes, and the table tool 7 in the present embodiment is a clock gauge.Said mandrel 4 places three joint cover inner chambers for stepped axle, 4 end of mandrel section and stage casing respectively with die sleeve 1 endoporus and shell 3 endoporus clearance fit, mandrel 4 tops with show tool 7 bar portion measuring junctions and contact.The present invention in mandrel 4 stage casings towards suit compression spring 5 between upper surface and the loam cake 6 top inner faces; Still keep table tool 7 bar portion measuring junctions to contact down in pretension compression spring 5 effect with mandrel 4 top end faces, directly formation show tool 7 bar portion measuring junctions with mandrel 4 along die sleeve 1 lumen shaft to the elastic telescopic structure.Be provided with the pad 2 of thick 2.0mm～5.0mm in said die sleeve 1 inner chamber; Thickness through transposing pad 2; Regulate mandrel 4 end section overhang; Overhang is greater than workpiece 8 axis hole seam vertical depth 0.5mm～1.0mm to be checked, and die sleeve 1 bottom face is provided with and the opposite but measure-alike sphere cavity of workpiece 8 axis hole seam end faces.The workpiece 8 that present embodiment is measured is the bevel planet gears in the sedan gear-box, and this gear axis hole seam end face is the SR45mm spherical surface body, and seam to sphere vertical depth is 1.0mm, and the seam diameter is Φ 20mm.Select for use the pad 2 of thick 3.0mm to place die sleeve 1 inner chamber, preset mandrel 4 stretches out 1.6mm from die sleeve 1 sphere cavity.During actual measurement, earlier with the pointer of same specification standard workpiece 8 adjustment form tools 7 to zero-bit, the workpiece 8 to be checked that changes the outfit is then shown the deviate that tool 7 pointer positions are the axis hole seam, deviate is judged to certified products in tolerance band, ultra scope be judged to unacceptable product.The present invention adopts the hand held structure, simple operation, and detection efficiency is high, adds to quantize to detect, and measurement result is accurate, can in time adjust axis hole seam working depth according to bias direction, promotes the crudy of axis hole seam greatly.
