Abstract

The invention discloses a flange hole center distance detecting tool used for detecting the distance between connecting holes distributed uniformly on the end face of a connecting flange of a cast tube (1) in the circumferential direction. The detecting tool (2) is provided with a detecting tool body (3) which is a square tube made of steel, two detecting insert blocks (4) are arranged on the same surface of the square tube and are fixedly connected with the detecting tool body (3), the detecting insert blocks (4) are in sliding fit with the connecting holes; and the center distance of the two detecting insert blocks (4) is equal to the center distance of two connecting holes distributed on the circumference of the connecting flange in the same diameter. By employing the above technical scheme, the flange hole center distance detecting tool can be operated simply and conveniently, and can detect workpieces accurately, the measuring error is reduced, and the detection efficiency is improved; the flange hole center distance detecting tool is simple in structure, low in manufacture cost, and high in repeating utilization factor; the flange hole center distance detecting tool is high in precision, and can detect whether the flange hole center distance has offset or not and the flange hole ellipticity effectively and quickly.

Description

technical field

[0001] The invention belongs to the technical field of measuring tools for industrial products. More specifically, the present invention relates to a flange hole center distance checker. Background technique

[0002] In the prior art, a vernier caliper is usually used to measure the center distance, but this method has the following problems:

[0003] 1. Inconvenient operation and low efficiency: When using a vernier caliper to measure the center distance of the flange hole, the result must be recorded after the measurement, and compared with the query standard, so as to determine whether the product is qualified. The center distance of a flange must be tested for multiple sets of holes before it can be judged. The inspection intensity is high and the efficiency is low.

[0004] 2. To measure the center distance of the flange with a vernier caliper, the center distance must be obtained by converting the results of the two measurements of the hole top dista...
