Abstract
The utility model discloses a kind of can the measurement mechanism of Quick Measurement trisection impeller of rotor external diameter, comprise and measure body and be arranged at the dial gauge measuring body side, described measurement body is that annulus measures body, and annulus is measured in body ring to be had the measurement button of annulus trisection.This measurement mechanism also comprises the ring gauge suitable with measuring body, and described ring gauge is connected with measurement body by folding fastener, can overlap, carry out school zero to measurement body by folding fastener is folding with measurement body.The utility model structure is simple, and with low cost, practicality is high; And supporting calibration ring gauge, adopt comparison expression to measure, measuring accuracy is higher, can meet need of production.
Description
Technical field
The utility model relates to a kind of measurement mechanism, particularly a kind of can the measurement mechanism of Quick Measurement trisection impeller of rotor external diameter.
Background technology
The plant equipment such as fan blower, air compressor is widely used in the industrial circles such as environmental protection, electric power, oil, chemical industry, grain conveying.
Root's blower is a kind of two-spool compressor tool, the axis of two rotors is parallel to each other and does the contrary constant speed rotation in direction, between power rotor and driven rotor, rotor and housing, all must ensure gap accurately and reliably between wallboard, just can guarantee equipment Effec-tive Function steady in a long-term, therefore the impeller outer diameter of rotor is a critical size, must be controlled.Traditional rotor is two leaves, similar " 8 " font, and common outside micrometer can be adopted to measure.But in order to reduce air pulsing, reduce noise, current two leaf rotors are replaced by three lobe rotor gradually.
Due to the impeller that three lobe rotor has 120 degree, three intervals uniform, its three summits form an equilateral triangle, therefore, its external diameters of gage measuring such as conventional outside micrometer cannot be used, usual vernier depth gauge or the height of miking impeller summit to axle surface and the external diameter of axle in production practices, by calculating impeller outer diameter, efficiency is lower, and measuring accuracy is poor.The good unit of some condition directly adopts three coordinate measuring machine to measure, although solve the problem of measuring accuracy, because usual three coordinate measuring machine requires higher to measurement environment, therefore cannot on-line measurement, and be not easy to the application in producing.
Summary of the invention
Goal of the invention: technical problem to be solved in the utility model is the problem that traditional ash bucket seals easy dust stratification and conventional helical conveying device function singleness.
Technical scheme: the utility model adopts following technical scheme: a kind of can the measurement mechanism of Quick Measurement trisection impeller of rotor external diameter, comprise and measure body and be arranged at the dial gauge measuring body side, this measurement mechanism also comprises the ring gauge suitable with measuring body, and described ring gauge is connected with measurement body by folding fastener.
As optimization, described measurement body is that annulus measures body.
As optimization, described annulus is measured in body ring to be had the measurement button of annulus trisection.
As optimization, the described measurement button by annulus trisection have at least one with the line of the dial gauge external diameter perpendicular to this line and annulus point of intersection annulus.
Principle of work: during use, first ring gauge and annulus are measured body and be folded to coincidence by folding fastener, body is measured to annulus and carries out school zero, open ring gauge by folding fastener, trisection blade is directly put into annulus and measure body, measure body with annulus to measure product to be checked, by measuring, button can directly whether visual observation blade be qualified, visually cannot directly confirm from dial gauge, directly to read counting again, this device long service life, measuring accuracy is high, realistic request for utilization.
Beneficial effect: the utility model compared with prior art: the utility model structure is simple, with low cost, practical; And supporting calibration ring gauge, adopt comparison expression to measure, measuring accuracy is higher, can meet need of production.
Accompanying drawing explanation
Fig. 1 is that the utility model folding fastener opens main TV structure schematic diagram;
Fig. 2 is the main TV structure schematic diagram that the utility model folding fastener overlaps;
Fig. 3 is the virtual condition schematic diagram that the utility model is measured blade.
Embodiment
The utility model provides a kind of thinking and method; the method and access of this technical scheme of specific implementation is a lot; the above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art, under the prerequisite not departing from the utility model principle, some improvements and modifications can also be made; these improvements and modifications also should be considered as protection domain of the present utility model, and all available prior art of each ingredient not clear and definite in the present embodiment is realized.
As 3 one kinds, accompanying drawing 1 to accompanying drawing can the measurement mechanism of Quick Measurement trisection impeller of rotor external diameter, comprise and measure body 1 and be arranged at the dial gauge 2 measuring body 1 side, this measurement mechanism also comprises the ring gauge 3 suitable with measuring body 1, and described ring gauge 3 is connected with measurement body 1 by folding fastener 4.Described measurement body 1 is annulus measurement body.Described annulus is measured in body 1 ring to be had the measurement button 5 of annulus trisection.The described measurement button 5 by annulus trisection have at least one with the line of dial gauge 2 external diameter perpendicular to this line and annulus point of intersection annulus.
During use, first ring gauge 3 and annulus are measured body 1 and be folded to coincidence by folding fastener 4, body 1 is measured to annulus and carries out school zero, open ring gauge 2 by folding fastener 4, trisection blade is directly put into annulus and measure body 1, measure body 1 with annulus to measure product to be checked, by measuring, button 5 can directly whether visual observation blade be qualified, visually cannot directly confirm from dial gauge 2, directly to read counting again, this device long service life, measuring accuracy is high, realistic request for utilization.
