The measurement of traditional belt pulley length size, all adopts general measuring method, carries out manual operations measurement by instruments such as vernier calliperss.
It is low to there is efficiency in this kind of metering system, controlled by the both hands of people when measuring, the accuracy that impact is measured, measurement parallax is there is again when reading, this brings very big error all to the result measured, these traditional check systems obviously can not meet the technical development trend of modern mechanical industry, through extensively retrieving, not yet finds ideal technical scheme.
Summary of the invention
When it is an object of the invention to solve present stage measurement pulley centers bore dia size, the shortcomings such as the efficiency of existence is low, take off data is accurate not, and the belt wheel inner hole diameter measurement device proposed.
In order to realize above-mentioned purpose, present invention employs following technical scheme:
Belt wheel inner hole diameter measurement device, it is characterised in that comprising:
A, base, connect gas momentum instrument and permanent seat respectively on base;
B, be connected end cap on permanent seat, is flexibly connected a resistance conductance cover, is provided with through hole on permanent seat between permanent seat and end cap, be connected mandrel in through hole, mandrel runs through resistance conductance cover, is also provided with spring between permanent seat and resistance conductance overlap, and spring is socketed on mandrel;
C, being provided with a main pipeline in described mandrel, be provided with at least one small transfer line on main pipeline, the opening of each small transfer line is arranged on the side of mandrel, and described main pipeline connects gas momentum instrument by pipeline.
On the basis of technique scheme, it is possible to have following further technical scheme:
Described base is connected on detector, and detector is connected with gas momentum instrument.
The described small transfer line on main pipeline is connected to its end, and small transfer line is the thin straight pipe of its place mandrel kernel of section of a mistake.
Being equipped with ladder hole on described permanent seat and end cap, the ladder hole on permanent seat and end cap is mutually corresponding, and spring is arranged in two ladder holes, contacts cooperation with the bottom surface in two ladder holes.
Described detector has data storage function, can read measured data with the display screen of detector and store the data after measuring.
Detector connects three mandrels simultaneously, the different diameter of bore of different belt wheels can be measured simultaneously, the data measured are recorded on detector, the interior hole corresponding matching of the small transfer line in mandrel and tested belt wheel when measuring, when accident, resistance conductance is put top by spring, small transfer line in mandrel is sealed by resistance conductance cover, prevents gas leakage.
This device utilizes the principle comparing method of masurement, first standard block is socketed on mandrel, after ventilation is measured, gentle for detector momentum instrument is reset, again tested belt wheel is socketed on mandrel, measure the tolerance numerical value of diameter of cylinder needing to measure, thus draw the belt wheel surveyed whether in standard range. The detected result of each detection station can be displayed on the display screen of detector, and carry out judging respectively for each detection data and point out OK or NG, automatically draw out curve of cyclical fluctuations figure respectively for each detection data, to facilitate the timely pre-setting finish size of processing person, ensure quality product.
It is an advantage of the current invention that: this apparatus structure is simple, it may also be useful to convenient, the speed of measurement is fast, precision height, it is to increase working efficiency, for the quality control of belt pulley provides effective technical data, for the processing of belt pulley provides effective measuring apparatus.
