Embodiment Construction

[0017] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0018] Such as figure 1 and figure 2 As shown, the large-diameter O-ring diameter measuring tool of the present invention is mainly composed of a base 1 and a slide table 2, which can slide relative to each other along the axis through the cooperation of dovetail guide rails. There are first cylinder 11 and second cylinder 22 on the base 1 and slide 2 respectively, both of which have a diameter of D1, and the distance between the centers of the two cylinders is L1, and the line connecting the centers of the circles with the base 1 and slide 2 The axes of relative sliding are parallel. Put the O-ring 4 to be tested between the first cylinder 11 and the second cylinder 22 and stretch it straight, then the diameter (in...

Abstract

The invention discloses a large-diameter O-shaped ring diameter measuring tool which comprises a base and a sliding table, wherein a first cylinder with the diameter being D1 is arranged on the base, the sliding table is connected with the base in a sliding mode, a second cylinder with the diameter being D1 is arranged on the sliding table, the connecting line of circle centers of the two cylinders is parallel to an axis, and the base and the sliding table slide relative to the axis. In work, an O-shaped ring to be measured is arranged on the two cylinders in a sleeved mode, the base and the sliding table relatively slide to adjust the distance L1 between the two cylinders, the O-shaped ring to be measured is tightened to be straight, and the diameter D of the O-shaped ring to be measured is equal to D1+2*L1 / pi according to the diameter D1 of the cylinders and the distance L1 of the circle centers of the two cylinders. The measuring tool is convenient to operate and high in measuring result precision.

Description

technical field [0001] The invention relates to the technical field of measurement, in particular to a large-diameter O-ring diameter measuring tool. Background technique [0002] At present, for small diameter O-rings, the projection method is generally used to accurately measure, but for large-diameter O-rings, because the ratio of diameter (inner diameter) to cross-sectional diameter is relatively large, the O-ring cannot maintain a standard circle, so it cannot be measured. Use calipers or projection equipment to measure its diameter, and generally use a soft tape measure to measure its circumference and convert it into a diameter. However, to measure the diameter of the O-ring with a soft tape, the operator needs to straighten the O-ring section by section and stick the tape close to it for measurement. The operation is more troublesome, and the accuracy of the measurement result is not high. Contents of the invention [0003] The purpose of the present invention is ...
