Description
Technical field
The present invention relates to a kind of metering outfit, specifically, is a kind of outer cone detector of measuring outer cone part or feeler gauge.
Background technology
Measuring outer cone the most frequently used measurer is ring gauge, in order to ensure that ring gauge measures the accuracy of outer cone, before detection, ring gauge taper hole and outer cone part must be cleaned out, then on ring gauge dyeing inspection part tapering degree of adhesion.If ring gauge is firmly excessive in the time measuring, part outer cone diameter measured value can be large, and ring gauge inspection is firmly too little, and part outer cone diameter measured value can be little, and measurement must be unloaded inspection from lathe at every turn, and operator's labour intensity is heavy.
Large outer cone cannot detect with large-scale ring gauge, generally adopts three coordinate meterings, and operator according to three coordinate metering result debugging taper ratios, finally determines outer cone size again, and production efficiency is extremely low.Existing outer cone measuring instrument complex structure, manufacturing cost is high, and measurer volume weight is large, and detection efficiency is low.
Summary of the invention
The present invention is directed to and in prior art, exist defect that a kind of lightweight, easy and simple to handle, outer cone detector that detection efficiency is high simple in structure is provided.
For realizing above-mentioned technical purpose, the technical solution used in the present invention is as follows:
A kind of outer cone detector, comprise arc locating device, backstay, gauge stand and two clock gauges, gauge stand is wherein vertically fixed in one end in described arc locating device two ends, described backstay has two, be separately positioned on the arc locating device other end and middle part, and the radial location steel ball that is respectively equipped with the tested outer cone part external diameter of coupling on backstay, described two clock gauges are packed on gauge stand up and down, and the gauge head of clock gauge is towards tested outer cone part external diameter surface.
Adopt the outer cone detector of technique scheme, by controlling clock gauge gauge head to the large end end face axial of outer cone part distance, be converted into by measuring cone diameter the state of measuring body diameter.Its measuring principle is as follows: detector is placed on standard outer cone part or feeler gauge end face, limit the axial restraint length of clock gauge outer cone measurement point to end face by arc locating device, when two radial location steel balls and outer cone part external diameter tangent after, proofreading and correct clock gauge reading value is 0, can judge outer cone outside diameter, taper ratio, circularity, linearity etc. by the error amount of clock gauge measurement of comparison.The concrete grammar of proofreading and correct clock gauge cuts except segmentation, can also standard feeler gauge or on measuring the part after qualified direct check and correction clock gauge, then according to the direct feed processing of measurement of comparison surplus.
Further limit, described arc locating device bottom is at least provided with three axial location steel balls.It is convenient that the setting of axial location steel ball facilitates arc locating device to move, and limits axial restraint length more effective.
Further limit, the distance of described two clock gauges and the large end of tested outer cone part is respectively 12mm and 112mm.
The present invention compared to existing technology, simple in structure lightweight, easy and simple to handle, detection efficiency is high, can detect outer cone size, taper ratio, circularity and linearity, and can directly detect the part in lathe clamp position; Clock gauge reading value, after standard cylinder check and correction, can also substitute outside micrometer and accurately measure outside diameter in addition; Detector actual measurement taper hole diameter reaches Φ 600mm, but only 3kg of weight, if arc locating device is expanded, detection outer cone diameter also can infinitely increase, this outer cone detector duplicate measurements error amount is not more than 0.001mm, the special adaptation production of part in batches.

Embodiment
In order to make those skilled in the art, the present invention may be better understood, below in conjunction with drawings and Examples, the technical program further illustrated.
As depicted in figs. 1 and 2, a kind of outer cone detector that is applicable to detect large outer cone, comprise arc locating device 1, backstay 2, gauge stand 3 and two clock gauges 4 of semicircle arcuation, gauge stand 3 is wherein vertically fixed by bolt in one end in described arc locating device 1 two ends, arc locating device 1 bottom is provided with three axial location steel balls 11, it is moved convenient, limit axial restraint length more effective.Described backstay 2 has two, be separately fixed at arc locating device 1 other end and middle part, and on backstay 2, be respectively equipped with the radial location steel ball 21 of tested outer cone part 5 external diameters of coupling, described two clock gauges 4 between the upper and lower distance are 100mm, be packed on gauge stand 3 by hexagon socket head cap screw respectively, its gauge head is all towards tested outer cone part 5 external diameter surfaces.
As shown in Figure 3, the measuring principle of this outer cone detector is as follows: detector is placed on standard outer cone part 5 or feeler gauge end face, limit the axial restraint length of clock gauge 4 outer cone measurement points to end face by arc locating device 1, after two radial location steel balls 21 and outer cone part 5 external diameters are tangent, proofreading and correct clock gauge reading value is 0, can judge outer cone outside diameter, taper ratio, circularity, linearity etc. by the error amount of clock gauge measurement of comparison.
Concrete using method:
1, determine taper ratio (in the situation that there is no standard outer cone part or feeler gauge)
1. the large footpath of standard outer cone part Φ 600mm, taper ratio 1:50, stays mill amount 0.5mm before finished product.
