Description

Technical Field

[0001] The utility model relates to a quick detection ring gauge for outer diameter. Background Art

[0002] The methods for detecting the outer diameter of circular parts usually include: micrometer measurement, three-coordinate measurement, etc.

[0003] The micrometer measurement method only requires a micrometer with a sufficient range to measure the outer diameter of the product along the diameter direction. At present, many factories still mainly use micrometers for measurement. When using a micrometer to measure the outer circle, you need to pay attention to the following points: choose a suitable measurement position. The diameter of the outer circle may have a slight deviation. To avoid errors, it should be measured at multiple positions and the average value should be taken; in order to ensure the accuracy of the measurement results, it is necessary to apply appropriate force during measurement to make the large micrometer fit the object being measured;

[0004] Coordinate measuring machines are widely used in measurement. During measurement, the probe moves on the sample, measures the data of each measuring point relative to the measurement reference according to the selected distribution points, and then evaluates the outer diameter size after data processing. The measurement accuracy of the probe is very high, but its efficiency is low. It usually takes several minutes for one sample, which is far from the expected production cycle.

[0005] Accuracy (comprehensiveness) of test results: Traditional testing has certain testing defects, such as the detection position and measurement force of the micrometer; the area, number of points, and environmental requirements of three-coordinate measurement, which cannot comprehensively and accurately measure the true status of the product.

[0006] Traditionally, measuring the outer diameter by micrometer, three-coordinate measurement, etc. usually takes several minutes, sometimes tens of minutes. And it has high requirements for the inspection personnel. Non-professionals cannot complete the inspection, which is inefficient and seriously affects the continuity of production.

[0007] In view of the above problems, the purpose of the utility model is to provide a quick outer diameter detection ring gauge which improves detection efficiency and production efficiency.

[0008] The technical solution to realize the utility model is as follows

[0009] A quick detection ring gauge for outer diameter comprises a gauge body, one end of which is provided with a first conical detection hole, and the other end of which is provided with a second conical detection hole; an observation area is formed between the first conical detection hole and the second conical detection hole; and both ends of the gauge body are covered with protective covers.

[0010] The inspection tool body in the observation area is a hollow structure, and a plurality of discontinuous observation grooves are evenly distributed on the outer surface of the inspection tool body in the observation area.

The conical detection holes of this gauge body are all designed with a taper; the inner diameter of the conical detection hole is larger at one end and can be designed according to the upper difference of the product, and the other end is smaller and designed according to the lower difference of the product. Both ends of the gauge body have a conical detection hole, and the two conical detection holes can be set to different sizes, so that one gauge can detect two different models of products.

[0022] The inspection tool body in the observation area is a hollow structure, and the outer surface of the inspection tool body in the observation area is evenly distributed with a number of discontinuous observation grooves 6.
