Abstract
The utility model discloses a universal detection device for rapidly and accurately detecting the inner diameter of a rubber ring, comprising a cone cylinder. Conical degree of the cone cylinder is 1: 10. Scale is engraved in the generatrix direction of the cone cylinder surface. Each scale value is corresponding to the inner diameter of rubber rings of different specifications. According to the utility model, scale is uniformly engraved on the periphery of the cone cylinder, the allowed maximum and minimum diameters of a rubber ring on the cone part are far away from each other, the rubber ring will not naturally drop into the cone cylinder under no external force deformation, and detection errors under external force are reduced. After the rubber ring is nested, it is very easy to see whether it accords with drawing requirements. The universal detection device has advantages of rapid and accurate detection and very high detection efficiency. The universal detection device can be universally used for various rubber ring specifications, and can be used to rapidly detect many specifications of large-batch round rubber seal rings with various cross-section shapes (such as rectangle, O-shape and D-shape).
Description
Technical field
The utility model relates to a kind of survey instrument mainly for detection of the rubber ring internal diameter.
Background technology
The rubber rings that all use in a large number in the machinery industry assembling are that a kind of demand is large, and specification is wide in variety, the sealing medium that the internal diameter span is large.Rubber ring is according to the difference of purposes, specification size, and internal diameter is irregular differing also, and the tolerance that has only has ± 0.15mm.The minimum precision of rubber ring internal diameter commonly used is 0.1mm.The rubber ring material is soft, and yielding under external force, when it was carried out inner diameter measurement, elastic module was large, is not easy to control well tolerance.The simplest measuring method is contact method at present, and contact method is by vernier caliper measurement, and contact force requires to be not more than the method for 0.2N.The difficulty of vernier caliper contact measurement is that the dynamics that slide calliper rule open is difficult to hold, and is easy to make rubber part to produce distortion, causes measuring error, measures inaccurate.Another kind method is eyes with non-contact method.Eyes with non-contact method is the method for carrying out projection measurement by projector.Although this method accuracy of detection is higher than contact method, it is high that projector is measured the cost that detects, and efficient is low, in actual use, still can not satisfy the current demand that the O-ring seal specification is wide in variety, demand is large.
Summary of the invention
The purpose of this utility model is the weak point that exists for above-mentioned existing detection method, provides a kind of easy to operate, and efficient is high, high, the applicable wide universal detection device of specification limit of accuracy of detection.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of universal detection device that quick and precisely detects the rubber ring internal diameter, comprise a frustum of a cone cylinder, it is characterized in that, described frustum of a cone cylinder taper value is 1:10, generatrix direction at this frustum of a cone cylinder is carved with scale mark, and each scale value correspondence the rubber ring internal diameter of different size.
Utility model has following beneficial effect than prior art.
The utility model engraves scale equably at frustum of a cone cylinder periphery, make on the conical section and to show between maximum that O-ring seal allows and the minimum diameter relatively far apart, in the situation without external force deformation, allow rubber ring naturally drop into frustum of a cone cylinder, reduced the detection error under the External Force Acting.Be easy to find out whether it meets drawing requirement after being inserted in rubber ring.Detect fast, accurately, detection efficiency is very high.One cover pick-up unit can satisfy rubber seal specification general of many kinds.(rectangle, O shape, D shape) round rubber O-ring seal of the multiple section shape that but the fast detecting specification is many, batch is large.Detect simple and convenient, quick and precisely, saved testing cost.
Description of drawings
Fig. 1 is the universal detection device principle schematic of this detection rubber ring internal diameter.
Fig. 2 is for detecting the universal detection device perspective view of rubber ring internal diameter
Fig. 3 is the local groove enlarged drawing of Fig. 2
Among the figure: 1 rubber ring, 2 rubber rings allow the minimum groove of internal diameter, and 3 rubber rings allow the maximum groove of internal diameter, 4 frustum of a cone cylinders, 5 bases, 6 handles, 7 screws.
Embodiment
Consult Fig. 1-Fig. 3.In the universal detection device of the detection rubber ring internal diameter that following examples are described, the frustum cylinder 4 that to have a taper value be 1:10, frustum of a cone cylinder 4 are fixed on the Universal base 5 with handle 6.Be the scale mark that the generatrix direction of the frustum of a cone cylinder of 1:10 evenly is carved with reflection rubber ring diameter at this taper value.Rubber ring 1 internal diameter of different size, the every increase of cone diameter 0.1mm is axially with alternation 1mm.Press the even groove of 1mm spacing in frustum of a cone damaged surface, each scale value correspondence the rubber ring internal diameter of different size.Distance between the minimum groove 2 of rubber ring permission internal diameter and the maximum groove 3 of rubber ring permission internal diameter is greater than the height of rubber ring.
The maximal value d1=D1-h1/10 that the rubber ring internal diameter allows, the minimum value d2=D1-h2/10 that the rubber ring internal diameter allows, and h2-h1=10 (D1-d2-D1+d1)=10 (d1-d2)=10 △ d (10 times of tolerance ranges) is arranged
In the formula: D1 is frustum of a cone cylinder base diameter, vertical range between the h1 maximal value that to be frustum of a cone cylinder bottom allow to the rubber ring internal diameter, vertical range between the h2 minimum value that to be frustum of a cone cylinder bottom allow to the rubber ring internal diameter, Δ d is tolerance range.
According to specification limit (Φ 6～Φ 100) mm of common rubber ring, the utility model rubber ring inside diameter detection device step-by-step design four groups of frustum of a cone cylinders, be used for the rubber ring (as shown in table 1 is the size value of various cones) of different-diameter specification.Before the detection, the corresponding frustum cylinder 4 of the rubber ring internal diameter of required check is connected with base 5 usefulness screws 7, lies on the work top, during detection, allow rubber ring naturally fall from upper, visual rubber ring is stuck in the scale value on the frustum of a cone cylinder, if between the id tolerance bound, be qualified.
Table 1 has been described the embodiment of several different sizes of the utility model
