Abstract
The invention relates to an inside diameter detection device for an O-shaped rubber ring. The inside diameter detection device comprises a measuring mandrel, a leveling sleeve, a tray and a dial indicator, wherein the outer side of the measuring mandrel is sleeved with the leveling sleeve positioned below a weight tray; the dial indicator is positioned on the tray; a conical surface is arranged at the upper part outside the measuring mandrel; a cylindrical surface is arranged at the lower part outside the measuring mandrel; and the conical surface is coaxial with the cylindrical surface. The tray is adjusted by the leveling sleeve to compress the O-shaped rubber ring. The inside diameter detection device is simple in principle, convenient to operate and stable and reliable in detection; and according to the inside diameter detection device, the problem that an original O-shaped rubber ring is inconvenient to measure the inside diameter and is not high in detection precision are solved and the detection requirement of the inside diameter of a precise O-shaped rubber ring can be met.
Description
Technical field
The present invention relates to a kind of pick-up unit, especially a kind of O type rubber ring internal diameter pick-up unit.
Background technology
In the prior art field, the detection method of O type rubber ring internal diameter is a lot, comprising " slide calliper rule detect, and feeler gauge detects, the cone detection, optical instrument detects " etc.Because the sulfuration of O type rubber ring is out of shape and is received the external force effect yielding, so detect O type rubber ring internal diameter with slide calliper rule and feeler gauge, error is bigger, and the internal diameter that can only satisfy the O type rubber ring of low accuracy class detects requirement.If the distortion of O type rubber ring internal diameter less (general 0.1 times of being not more than id tolerance with internal diameter circularity); Then can satisfy the internal diameter detection requirement of micron order O type rubber ring with the optics instrument detecting; But costing an arm and a leg of optical instrument, and receive the influence of O type rubber ring distortion very big.For existing cone detection method, learn that from Patent document data and O type rubber ring professional production producer existing cone pick-up unit comes with some shortcomings, use less.As: the patent No. is the cone pick-up unit of ZL200520043554.6, and this device principle of work is: O type rubber ring is contained on the cone, at the cone small end with the kuppe that is threaded; Between kuppe and the cone small end even slit is arranged; Forced draft flows out from the slit, and air-flow brings pressure to bear on the O type rubber ring, makes O type rubber ring be close to cone; Measure the position that O type rubber ring is positioned at the cone short transverse with measurer, calculate the internal diameter size of O type rubber ring according to relevant geometric relationship.The deficiency that this device exists: 1, inconvenient operation, an O type of every survey rubber ring all must unload the kuppe of small end and load onto, and when big as if O type circle, operation is more inconvenient.2, the air pressure that is applied on the O type rubber ring is uncontrollable, the air pressure that key reaction is flowed out from the distance and the slit of kuppe at O type rubber ring.3, the verticality of O type rubber ring and cone is uncontrollable, can cause the detection error.4, detecting O type rubber ring, to be positioned at the site error of cone short transverse bigger, mainly is reflected in the verticality problem of O type rubber ring and cone and the error of survey instrument itself highly.
Summary of the invention
For addressing the above problem, the invention reside in provides a kind of structural principle simple, easy to operate, detects reliable and stablely, can satisfy the internal diameter pick-up unit that micron order O type rubber ring internal diameter detect to require.
The said O type of the present invention rubber ring internal diameter pick-up unit; Comprise and measure mandrel, leveling sleeve, pallet and dial gauge that wherein the leveling sleeve is placed in and measures the mandrel outside, is positioned at pallet); Dial gauge is positioned on the pallet; The outer upper of measuring mandrel is the conical surface, and the bottom is the face of cylinder, and the conical surface is coaxial with the face of cylinder.
Pallet has the ring flange of placing counterweight, and the top has boss, and dial gauge is positioned on the boss.
The endoporus of leveling sleeve and face of cylinder clearance fit, the both ends of the surface of leveling sleeve and the endoporus axis normal of himself of measuring mandrel.
To its relative position for the conical surface of O type rubber ring adjustment to be detected, the method that adds counterweight through pallet applies vertical pressure to O type rubber ring, makes it be close to the conical surface through the leveling sleeve in the present invention.Measuring at this moment with dial gauge, the boss end face then can calculate the internal diameter of O type rubber ring through geometric relationship to the distance of measuring the mandrel bottom surface.
Beneficial effect of the present invention is: cone is adopted in (1), can eliminate the distortion of O type rubber ring, and the internal diameter of O type rubber ring is detected the position probing that is converted into the O type rubber ring place conical surface, amplifies margin tolerance by tapering.(2) utilize leveling sleeve leveling O type rubber ring, reduce to detect error.(3) exert pressure for O type rubber ring with counterweight, eliminate O type rubber ring and measure the gap between the mandrel conical surface, and guarantee that pressure is controlled.(4) adopt dial gauge to detect the position that O type rubber ring is positioned at the side face mandrel conical surface, precision is higher, and is easy to use.Solved existing detection method operation inconvenience, the problem that precision is not high.
