Abstract
The utility model relates to a large rubber O-shaped sealing ring length measuring device which comprises a roller, bearing supports which are arranged on the front side and the rear side of the roller, open type semi-circular brackets which are arranged on the upper parts of the bearing supports, and support bases supporting the bottom of the bearing supports. The center of the roller is provided with a central shaft; both ends of the central shaft are arranged in the open type semi-circular brackets of the bearing supports in a rotating way; and the front side and the rear side of the roller are provided with flanges. The edge of the outer diameter of the side surface of the roller is provided with scales which are divided by 1 millesimal. The large rubber O-shaped sealing ring length measuring device adopts a device similar to the a roller structure; the measuring result on the large O-shaped sealing ring is that the circumference of the inner diameter of the O-shaped sealing ring directly divided by Pai makes the inner diameter of the O-shaped sealing ring; the inner circumference of the O-shaped sealing ring can be conveniently and quickly read directly, thereby simplifying the measuring procedures, improving the measurement precision and meeting the detection requirements.
Description
Technical field
The utility model relates to packoff, particularly a kind of device for measuring length of large-scale RUBBER O RunddichtringO.
Background technology
The O RunddichtringO is a kind of circular O-ring seal of round section.The dimensions of O RunddichtringO defines according to its internal diameter and diameter of section.The O RunddichtringO is applicable to different types of fixing seal or motive seal occasion.O RunddichtringO cost is low, and is easy to use effective, is widely used.
Usually RUBBER O RunddichtringO sulfidization molding in mould, but some rubber such as fluororubber need post-cure, sulfuration for the second time be mould outside under the free state high temperature vulcanized once more back finalize the design.Because post-cure technology difference, factor such as temperature, time for example, the product after the post-cure causes that because of shrinkage factor is different there is some difference in its circumferential length, therefore need be to the one by one inspection of O RunddichtringO.
The instruments of inspection of check O RunddichtringO adopts straight steel ruler, checkout procedure is to make start mark earlier on the O RunddichtringO that is verified, measure one by one again to former starting point, with the middle electrical path length of each section measured value sum as tested O RunddichtringO, calculate the interior electrical path length of tested O RunddichtringO again according to O RunddichtringO line footpath diameter of section, be converted into the O RunddichtringO internal diameter of standard-required then.Adopting this kind method to measure needs the stretching piecemeal measurement of O RunddichtringO, and therefore stretching used power exist certain difference only with people's feel and range estimation; Because of the cumulative errors of measuring piecemeal cause measurement result to have bigger error, especially when measuring large-scale O RunddichtringO such as the O RunddichtringO more than the diameter 2m, the data error that obtains is more obvious again.
The utility model content
In order to overcome the shortcoming of above-mentioned prior art, task of the present utility model provides a kind of large-scale RUBBER O RunddichtringO device for measuring length, and it has solved the problem that has when measuring the especially large-scale O RunddichtringO of O RunddichtringO than mistake.
Technical solution of the present utility model is as follows:
A kind of large-scale RUBBER O RunddichtringO device for measuring length, it comprises a roller, is placed in the prop of both sides, roller front and back, the open semicircle carriage of installing on prop top, and at the bottom-supported bracket base of prop; Described roller center is provided with central shaft, and the two ends of central shaft place in the open semicircle carriage of prop rotationally, and both sides are provided with rib before and after the roller; Outer diameter side edge place, described roller side is provided with scale, and scale is divided into 1 ‰.
Large-scale RUBBER O RunddichtringO device for measuring length of the present utility model adopts a kind of device of similar roller structure, the result that large-scale O RunddichtringO is measured is the girth of O RunddichtringO internal diameter, directly be the internal diameter of O RunddichtringO divided by π, simplify process of measurement thus, improved measuring accuracy.
Adopt the advantage of large-scale RUBBER O RunddichtringO device for measuring length of the present utility model as follows:
1, directly reads girth in the O RunddichtringO quickly and easily.
When 2, measuring the O RunddichtringO, the O RunddichtringO is subjected to the self gravitation factor sagging, its even tension, and the contrast of the O RunddichtringO of especially same specification is more definite.
3, measuring accuracy is accurate, and according to actual operating position, measuring accuracy can satisfy the detection requirement less than 0.2%.
Description of drawings
Fig. 1 is the structural representation of a kind of large-scale RUBBER O RunddichtringO device for measuring length of the present utility model.
Fig. 2 is the left view by device for measuring length shown in Figure 1.
Embodiment
Referring to Fig. 1 and Fig. 2, the utility model is a kind of large-scale RUBBER O RunddichtringO device for measuring length, and it mainly is made up of a roller 1, prop 2, open semicircle carriage 3 and bracket base 4.
Roller 1 center is provided with central shaft, and the two ends of central shaft place in the open semicircle carriage 3 of prop 2, and roller 1 central shaft can rotate in this open semicircle carriage 3 neatly.In both sides, roller 1 front and back rib 5 is set, the width that rib 5 height forms between should 1/2, two rib greater than O RunddichtringO 8 lines footpath diameter of section should be greater than the diameter dimension in O RunddichtringO 8 lines footpath.
1 side external diameter edge is provided with calibrated dial 6 at roller, and scale is divided into 1 ‰.The steely ruler of scale form class, that is: each little lattice of roller scale are 1mm, and lattice are 10mm in each, and each big lattice is 100mm.Each big lattice place of roller scale stamps steel impression mark from 0～900 successively.
In the actual measurement to large-scale RUBBER O RunddichtringO, roller 1 external diameter of device for measuring length made of the present utility model is Φ 318.31mm, and periphery is launched the long 1000mm that is.During measurement, lift roller 1 central shaft one end, penetrate O RunddichtringO 8, tested O RunddichtringO 8 is put into the periphery of roller 1, promptly in the groove between two ribs 5.Set level central shaft, axle head is in the open semicircle carriage 3.O RunddichtringO 8 remainders are influenced under the nature by dead weight power to fall, and O RunddichtringO 8 redundances then hang down in the neutral gear of prop 2 bottoms naturally.
Tested O RunddichtringO 8 is done a mark, make 0 of mark place and roller scale locate upwards to aim at.Shake roller 1 lentamente since the deadweight of O RunddichtringO itself and with the friction force of roller surface generation, make the same moved further of O RunddichtringO, shake the position that makes progress, O RunddichtringO start mark place until roller.
Direct reading, then Zhou Changdu is n circle (n * 1000mm)+number of division in the O RunddichtringO.All length overalls in the O RunddichtringO are the internal diameter of O RunddichtringO divided by π.
Certainly, those skilled in the art in the present technique field will be appreciated that, the foregoing description only is to be used for illustrating the utility model, and be not with opposing qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in the scope of the utility model claim conversion, the modification of the foregoing description.
