A precision measuring instrument for inner and outer diameters of large-diameter sealing rings

Abstract

The invention discloses a precision measuring instrument for the inner and outer diameters of a large-diameter sealing ring, which includes a precision measuring table, the precision measuring table is a hollow structure, and a first limit chute is opened inside the fixed placement plate, and the fixed placement plate A second scale mark is provided on the upper surface of the plate close to the side of the first limiting chute, and the inside of the first limiting chute is provided with a first measuring component. The second limiting chute and the third The inside of the limiting chute is provided with a second measuring component. The present invention can facilitate the user to quickly measure the outer diameter of the sealing ring through the first measuring component, improve the measurement accuracy of the outer diameter of the sealing ring, and facilitate the user to record the value of the outer diameter of the sealing ring. The second measuring component can It is convenient for the user to quickly measure the inner diameter of the sealing ring, saves the measurement time of the inner diameter of the sealing ring, and at the same time ensures the measurement accuracy of the inner diameter of the sealing ring.

Description

technical field [0001] The invention relates to the technical field of measuring equipment for inner and outer diameters of sealing rings, in particular to a precision measuring instrument for inner and outer diameters of large-diameter sealing rings. Background technique [0002] The choice of sealing ring material is of great significance to its sealing performance and service life. The performance of the material directly affects the performance of the sealing ring. Large-diameter sealing rings are widely used in machinery manufacturing, industrial production and workshop processing. Large-diameter sealing rings In the process of production and processing, it is necessary to effectively detect the inner and outer diameters of the finished product, so as to ensure the production quality of the product. [0003] A Chinese patent discloses a rubber sealing ring measuring tool and its measurement method (authorized notification number CN104567608 A). The rubber sealing ring m...

[0003] A Chinese patent discloses a rubber sealing ring measuring tool and its measurement method (authorized notification number CN104567608 A). The rubber sealing ring measuring tool of this patent technology can optimize the The measurement method of the rubber sealing ring can confirm the accuracy of the measurement, thereby ensuring the quality of the product. In addition, the Chinese patent also discloses a precision measuring instrument for the inner and outer diameter of the large-diameter sealing ring (authorized announcement number CN 207439384U). The precision measuring instrument for the inner and outer diameter of the diameter sealing ring has high measurement accuracy, high measurement efficiency, low cost, convenient measurement, and can adapt to the eccentricity problem caused by manual placement. This instrument is suitable for precision measurement of the inner and outer diameters of other circular parts, but the patent Although technology can solve the problem of measuring the inner and outer diameters of sealing rings, the cost is relatively high, and more equipment and instruments are needed to assist in the completion of the measurement work, which is time-consuming and laborious
