Description
Technical field:
The utility model relates to a kind of survey instrument, particularly relates to a kind of survey instrument detecting elastic seal ring internal diameter.
Background technology:
O-ring seal is the key components and parts of gland seal fit structure, the O-ring seal of current use is all resilient nonmetallic O-ring seals, use nonmetal O-ring seal can strengthen against leakage ability, the size of resilient nonmetallic O-ring seal directly has influence on the effect of sealing, for high-end precision equipment, especially high-end precision hydraulic pressure, pneumatic equipment, wherein the sealing property of O-ring seal requires high, the dimension precision requirement of O-ring seal is very high, the internal diameter precision of the O-ring seal that conventional equipment uses requires general at 0.1 ~ 0.5mm, and require high for the internal diameter precision of the O-ring seal that high-end precision equipment uses, id tolerance precision is at 0.01 ~ 0.05mm, due to, O-ring seal adopts compression molding, its machining tolerance can not reach high precision like this, therefore grouping must be detected one by one to processed O-ring seal, guarantee that the internal diameter size tolerance often organizing resilient nonmetallic O-ring seal meets the requirements, very difficult to the inspection of resilient nonmetallic O-ring seal, also there is no ready-made cubing at present, method can only be selected to carry out examination join by joining, turning seal groove is carried out according to O-ring seal, so not only production efficiency is extremely low, and, applicable O-ring seal is chosen with regard to more difficult after O-ring seal damages, such equipment just cannot ensure original sealed precision, in order to solve this technical barrier, applicant adopts group technology, measurement grouping is carried out to same specification mold pressing seal, ensure that the dimensional tolerence of every a small group inner seal liner all meets predetermined technique requirement, so just sealed precision can be ensured, later after seal damages, as long as the seal of joining same group can be changed by equally accurate, therefore, to carrying out detecting grouping one by one fast to O-ring seal.
Because nonmetal O-ring seal itself belongs to elastic deformation material, stressedly elastic deformation can be produced, traditional survey instrument is adopted to measure O-ring seal, exert oneself a little in measuring process, rubber seal will stress deformation, the stressed rear dimensional measurement of O-ring seal can produce deviation, causes measurement parameter inaccurate, directly arrives the quality of fit of the using state affecting rubber seal.In measuring process, the applying power of different operating person varies in size, and the elastic deformation that O-ring seal produces is different, has an impact to the result measured, and makes measurement result unstable.
Adopt the size of projective measuring instrument O-ring seal, although accurately can measure the dimensional accuracy of O-ring seal, because O-ring seal is the rubber parts of mold pressing, O-ring seal in a free state its internal diameter is not circle, but oval, therefore still accurately cannot measure the accurate size of internal diameter of the seal ring.Because it is get a little on the image of O-ring seal that projective measuring instrument carries out projection measurement principle to O-ring seal, according to the coordinate of taken point, calculate the internal diameter of O-ring seal; When reality detects, O-ring seal is placed on projector, can not ensure it must is circular, stressed a little during placement, profile may will change, in most cases, O-ring seal is oval when placing, a result calculated got by projector will be more much larger than the value of reality, and namely use projector repeated measurement, numerical bias is also very large.So due to O-ring seal material and structure, existing detection method accurately cannot measure the internal diameter size of O-ring seal, cannot ensure that O-ring seal meets state of the art.This projector precision measurement equipment price is very high simultaneously,
The applicant is through studying intensively, devise a kind of elastic seal ring precisely measuring inner diameter taper measurement chi, it accurately can not only detect the internal diameter of the elastic seal ring of same specification, and the consistance of duplicate measurements, production efficiency is high, without the need to special checkout equipment, simple to operate, easy to use, detection efficiency is high.
Utility model content:
The purpose of this utility model is to provide a kind of elastic seal ring precisely measuring inner diameter taper measurement chi, it accurately can measure the internal diameter size of elastic seal ring, not only simple and direct but also accurate, the repeatable accuracy detected is high, being specially adapted to the detection grouping of high precision elastic O-ring seal, is that high-end precision optical machinery is produced assembling, keeped in repair indispensable crucial cubing.
The technical scheme that the utility model is taked is as follows:
A kind of elastic seal ring precisely measuring inner diameter taper measurement chi, it is characterized in that: comprise taper measurement body, taper measurement body is the frustum of a cone, the top diameter of taper measurement body is less than the nominal bore diameter of elastic seal ring to be measured, the base diameter of taper measurement body is greater than the nominal bore diameter diameter of elastic seal ring to be measured, the outside surface of taper measurement body is provided with the rule measuring elastic seal ring internal diameter, and rule is arranged along axle, and the precision of rule is 0.01 ~ 0.1 millimeter.
Further, the outside surface of taper measurement body is provided with equably the rule that two to four are measured elastic seal ring internal diameter.
Further, the outside surface of taper measurement body is provided with equably the rule that two are measured elastic seal ring internal diameter.
Further, the measurement size scope of rule is greater than the tolerance range of the internal diameter size of O-ring seal to be detected.
The measuring method of elastic seal ring internal diameter size described in the utility model is as follows:
During measurement, O-ring seal to be detected is enclosed within the conical surface of taper measurement body from the top of taper measurement body, pressure seal ring is pressed downwards gently with finger, make the laminating with pressure of the outside surface of the inner ring of elastic seal ring and taper measurement body, reading corresponding on body high scale chi is measured by reading cone, directly can obtain the physical size of elastic seal ring internal diameter, divide into groups according to internal diameter of the seal ring dimensional values, guarantee that the tolerance of all internal diameter of the seal ring sizes in each group is in preset range, improve each group internal diameter of the seal ring dimensional accuracy, make it the precision-fit requirement meeting high-end devices.Realization conventional seals circle molding apparatus produces O-ring seal, the precision-fit requirement adopting special go-on-go instrument to meet high-end precision equipment to propose O-ring seal.
Because the utility model is frustum of a cone body testing tool, it is determine according to the precision of rule and internal diameter of the seal ring dimensional tolerance range to be checked that cone measures the tapering of body, and such as, the range of size of internal diameter of the seal ring is 50
-0.5~ 50 millimeters, its margin tolerance is 0.5 millimeter, if the precision setting of rule is 0.01 millimeter, the scale spacing of rule is 1 millimeter, and so the taper ratio of circular cone stage body is 1:100.Because the outside surface subscript measuring body in cone is marked with high-precision rule, directly elastic seal ring is enclosed within during measurement on cone measurement body and measures, the physical size of internal diameter of the seal ring just directly can be obtained by the reading reading the precision size rule that cone is measured on body, this testing tool structure is simple, easy to operate, accuracy of detection is high, human factor is little on the impact detected, go-on-go speed is fast, the consistance of duplicate detection is good, it accurately can measure the internal diameter size of elastic seal ring, not only simple and direct but also accurate, the repeatable accuracy detected is high, be specially adapted to the detection grouping of high precision elastic O-ring seal, that high-end precision optical machinery produces assembling, keep in repair indispensable crucial cubing.
