Description
Technical field
The utility model relates to a kind of general auxiliary detection device mainly for detection of R position two on part rib, edge strip and size, comprises the R circular-arc detection device containing two R male and fomale(M&F) arc transition workpiece.
Technical background
In machinery industry part manufactures, the transitional region on part rib or edge strip top, is all shaped with usually by concave surface circular arc and the tangent two R structures be formed by connecting of convex surface circular arc.The two R structures seamlessly transitted between rib or each end face of edge strip be eliminate muscle, edge strip sudden change stress is concentrated, and avoids assembling to scratch, and improves the transition face of assembling degree smoothly.Due to the singularity of two R structure, the measurement difficulty of R position is large, with conventional tool measure often can not find reference reference point, line or face.The detection method of current employing is numerically controlled measuring machine mensuration.Numerically controlled measuring machine mensuration is generally with three points on two R place concave surface circular arc or convex surface circular arc, determines concave surface or convex surface position by measuring three points on concave surface or convex surface.During measurement, each R at least will measure the position that three points just can fix R, if two R of measured part are more, will produce hundreds of measurement data, the data of measurement are more, and efficiency is lower, and cost is also higher.
Summary of the invention
The purpose of this utility model is the weak point existed for above-mentioned existing detection method, provides a kind of easy to operate, simply, efficiency is high, accurate positioning, and radius R size and position on part can be detected, quick and precisely the general R of the two R arc transition positional precisions in location advises combine detection measurer.
The utility model solves the technical scheme that its technical matters adopts: the general R of a kind of two R arc transition positional precisions advises combine detection measurer, comprise and be shaped with the convex R radius caliper recessed R radius caliper identical with radius measurement range, it is characterized in that, recessed R radius caliper described in convex R radius caliper described in a group and one group is by conventional two R arc radius size, with the combination of R0.5mm stepping, and on every sheet R radius caliper all with one through point of contact and the tangent origin reference location face of radius R; One group of convex R radius caliper and/or one group of recessed R radius caliper are movable respectively to be connected firmly in the one or both ends of protecting plate bracket frame, during measurement, according to the size of the two R convexity R or recessed R of part, choose the identical convex R radius caliper of radius value or recessed R radius caliper, be adjacent to recessed R or the convex R circular arc camber location of tested part, by the measuring surface of vernier caliper measurement radius caliper and the distance of part reference field, determine the position of the two R of tested part.
Utility model has following beneficial effect compared to prior art.
The utility model, by locating the two R place of laminating part with the radius caliper in origin reference location face and circular arc R, uses conventional tool vernier caliper measurement radius caliper measuring surface apart from the position of part reference field, thus determines the position of two R.The quick position that the general R of two R arc transition positional precision advises combine detection measurer solves routine measurement instrument cannot accurate location survey, the problem that measuring machine efficiency is low, cost is high.Fast, accurately, detection efficiency is very high in this auxiliary detection device location.A set of auxiliary detection device can meet the auxiliary detection of common dissimilar, different size part all pairs of R positions.Detect simple and convenient, quick and precisely, save testing cost.

Embodiment
Consult Fig. 1-Fig. 3, in the embodiment that following examples describe, the general R of two R arc transition positional precision advises combine detection measurer, comprises and is shaped with the convex R radius caliper 6 recessed R radius caliper 8 identical with radius measurement range.R advises general combined measuring tool and is combined by the recessed R radius caliper 8 that one group of convex R radius caliper 6 of shape is as shown in Figure 2 identical with one group of radius of shape as shown in Figure 3.Every sheet convex R radius caliper 6 and recessed R radius caliper 8 are respectively with an origin reference location face 1, and this origin reference location face 1 is through the point of contact 5 of recessed R or convex R.The convex R radius caliper combination that one group of recessed R radius caliper is identical with one group of radius, can meet auxiliary positioning and the measurement of conventional different R position and size.Be R3 ~ R25mm according to two R arc radius that part is conventional, recessed R radius caliper 8 described in R radius caliper 6 convex described in a group and a group can be set to 3 groups: R3 ~ R10mm; R10.5 ~ R17.5mm; R18 ~ 25mm.For adapting to the detection of tested part 15 different radii R, often group presses the combination of 0.5mm stepping.One group that radius is identical convex R radius caliper 6 and recessed R radius caliper 8 screw or rivet 9 are followed closely at the two ends of the thick protecting plate bracket frame 7 of 1mm.During measurement, according to the size of the two R convexity R or recessed R of part, choose the identical convex R radius caliper of radius value or recessed R radius caliper, be adjacent to recessed R or the convex R circular arc camber location of tested part, by the measuring surface of vernier caliper measurement radius caliper and the distance of part reference field, determine the position of the two R of tested part.
Consult Fig. 4.According to the difference of two R present position on part, so that be detected as principle, this couple of R can be detected and be divided into two types: a kind of is detect part convex R face determine one group of the position of two R convex R radius caliper 6 and detect one group of recessed R radius caliper 8 that the position of two R is determined in part recessed R face.The recessed R radius caliper 8 that one group of 2mm that one group of convex R radius caliper 6 being 2mm is thick is identical with radius is thick.Before detection, according to the size in tested part 15 pairs of R transition arc convexity R faces 14, choose the recessed R radius caliper 8 that radius value is identical, mobile recessed R radius caliper 8, fitted with part edge strip upper surface 10 in recessed R radius caliper 8 plane positioning face 11, recessed R radius caliper circular arc locating surface 13 is fitted with the convex R face 14 of part edge strip, and gapless is guaranteed in range estimation.Two types recessed R radius caliper 8 or convex R radius caliper 6 by the distance L of general testing tool vernier caliper measurement measuring surface 4 with part reference field, detect the position of two R after fitting with the concave surface in the convex R face in the two R of part and plane or two R and plane fast.
