The Wall-Thickness Difference of pin-type load cylindrical roller does not have special detecting instrument, and the general single mandrel that adopts is through in the endoporus of pin-type load cylindrical roller, then axle to be fixed on vice Rotational Cylindrical pin cylindrical roller to measure its Wall-Thickness Difference again.Because axle is not easy to be fixed firmly, particularly when the pin-type load cylindrical roller quantity measured is more, need repeatedly to adjust stationary spindle, often occur central axis phenomenon, Wall-Thickness Difference is measured inaccurate, affects the serviceable life of pin-type load cylindrical roller.
Summary of the invention
For solving above-mentioned Problems existing, the invention provides a kind of simple measurement method of pin type cylindrical roller wall margin, measurement efficiency and the measurement accuracy of pin type cylindrical roller wall margin can be improved, safe and convenient to use.
For achieving the above object, present invention employs following technical scheme:
A kind of simple measurement method of pin type cylindrical roller wall margin, tested pin-type load cylindrical roller has longer endoporus, the aperture of longer endoporus is D, described longer endoporus and its external diameter form wall thickness, Wall-Thickness Difference is formed by the wall thickness at its two ends of length direction of tested pin-type load cylindrical roller, described Wall-Thickness Difference can not be greater than design load, otherwise tested pin-type load cylindrical roller is just judged as substandard product, and feature of the present invention is:
T-shaped bolt is penetrated in the groove of measuring table, contour cushion block and base are placed on the both sides of T-shaped bolt, by pressing plate and nut, cushion block and base are fixed on described measuring table, one end of base arranges internal thread hole, the axle of mating with described internal thread hole is screwed on base, external diameter≤described the D of axle, the length of axle is greater than the interior hole length of tested pin-type load cylindrical roller, axle puts tested pin-type load cylindrical roller and tested pin-type load cylindrical roller is freely rotated around axle, clock gauge is configured above tested pin-type load cylindrical roller, clock gauge is placed in the left end of tested pin-type load cylindrical roller or right-hand member under tested pin-type load cylindrical roller stationary state and the reading of clock gauge is corrected to zero-bit, then under tested pin-type load cylindrical roller rotary state, level pulls clock gauge from left to right or from right to left, the relative position of clock gauge in horizontal drawing process does not change, now observe in detail and note down all changes value of clock gauge reading described in horizontal drawing process, maximal value in all changes value is the Wall-Thickness Difference of tested pin-type load cylindrical roller, this Wall-Thickness Difference and described design load are compared and just can judge whether tested pin-type load cylindrical roller is specification product.
Base is made by GCr15, and the hardness after base Quenching Treatment controls at 61 ~ 63HRC, and base does blackening process.
Owing to adopting technical scheme described above, the present invention produces following good effect:
1. supplemental measurement tool of the present invention makes simple, especially the external diameter of axle and length can be determined according to the endoporus aperture of tested pin-type load cylindrical roller and interior hole length, the Wall-Thickness Difference being not only applicable to the tested pin-type load cylindrical roller of batch is measured, and the Wall-Thickness Difference being applicable to the tested pin-type load cylindrical roller of different size is measured.
2. axle fixedly positioning on base by external thread, and how tested pin-type load cylindrical roller rotates all can not make axle produce relative rotation.
3, simple measurement method of the present invention can improve measurement efficiency and the measurement accuracy of pin type cylindrical roller wall margin, safe and convenient to use.
