Description

A kind of quick detection angles cubing

Technical field

The utility model belongs to dedicated inspection device, more particularly to a kind of quick detection angles cubing.

Background technology

Cubing is a kind of to be used for measuring dedicated inspection device with evaluating parts size quality.In part production scene, lead to Cubing realization is crossed to the on-line checking of part, needs part being installed in cubing exactly therefore, then passes through range estimation, or survey Scale, or slide calliper rule, to part type face, periphery is checked, can also be sold or be estimated to hole of different nature on part by examining And the coupled position between part and part carries out visual inspection, so as to ensure to realize that the quick of part quality state is sentenced in production It is disconnected.

Part assemblies product to be measured is to match somebody with somebody to attach together to force together by two parts bearing holder (housing, cover)s and balance weight to form a list The product of part, wherein sleeve diameter are had angle 7 ° by a plane is flat with center line shape, as Figure 1-Figure 2.According to production The processing at scene and detection actual conditions, it would be desirable to be able to directly quick measurement angle size.Usually there are following several measuring methods：

1st, universal protractor measurement method：

Universal protractor is otherwise known as angle block gauge, vernier angle scale and universal bevel protractor, it is to utilize vernier reading principle Come a kind of angle measuring tool for measuring corner of workpiece or ruling.Whether tester detects part qualified generally using light transmission method, inspection It being affected during survey by external factor, and bevel protractor is complicated for operation, it is desirable that operator has certain measurement experience, therefore for reality The production scene detection on border cannot meet simplicity, accurately require.

2nd, simple projection measurement mode：

Projection measurement is hinted obliquely at by light by measured workpiece measurement surface image zoom, is closed by operator according to image space System's conversion measurement result, operator is because the difference of every workpiece and the difference that walks cause reconnaissance to deviate, multiple frequent reconnaissance Cause measurement inaccurate with repeating to walk.

3rd, three-dimensional coordinates measurement mode：

Three-dimensional coordinates measurement is put into tested part in the range of the measurement space of its permission, accurately measures tested part table The point in face is in the numerical value of three coordinate positions in space, and by the coordinate values of these points by computer disposal, fitting forms measurement Element, the method by mathematical computations draw its shape, position of related features and other geometric sense data.Three-dimensional coordinates measurement precision can be with Reach ± 0.05mm, but three coordinates are difficult to accomplish that on-line checking judges product quality, do not meet production scene batch production detection It is required that it is quick, easily measure convenience.

The content of the invention

The purpose of this utility model is to provide a kind of quick detection angles cubing and its measuring method, which meets life Produce the on-line checking at scene it is succinct convenient, quick, intuitively require.

The purpose of this utility model and its technical problem underlying is solved using following technical scheme to realize：It is a kind of fast Fast detection angles cubing, including pedestal 4, pedestal 4 includes both sides bearing, and part 1 to be measured, plug 2 are supported by plug 2 on bearing On have flat block 3, flat block 3 is on right support abutment, and pinhole is packed into feeler gauge 5 on part 1 to be measured on left support abutment, installs on feeler gauge 5 Dial gauge 6.

In use, penetrating part 1 to be measured according to the plug 2 that inner hole of shaft sleeve size shape makes, it is placed on pedestal 4 and passes through core Horizontal plane of 3 centering of flat block on the basis of the angle flat horizontal surface of sleeve diameter on stick 2, pinhole leads on part 1 to be measured It crosses loading feeler gauge 5 and is used as measurement point, dial gauge 6 is installed on feeler gauge 5, the vertical range of peak to the base plane of feeler gauge 5 is For detected size.

The utility model principle：It, can be by the angle of part by mutually being converted between angle and the triangle relation of plane Degree is converted into the direct reading value of available measuring tool.Known axle sleeve hole center to pinhole centre distance L, flat horizontal surface offset L1, The relative dimensions such as the angle beta solved, the diameter D of feeler gauge are needed, it is as follows to measure size formula：L*Sinβ+L1+D/2.

The utility model has clear advantage and advantageous effect compared with prior art.From above technical scheme, The utility model makes the detection of product, and quality can be monitored effectively in prolonged application, and client's approval absolutely proves this Cubing can accurately detect accessory size.Therefore the detection of similar angle can be promoted with the method, can be quick, it is easy, intuitively The cubing as on-line checking.
