Problems solved by technology

Although the size of the counterbore can be measured using a three-coordinate measuring instrument, its measurement accuracy is directly proportional to the number of measurement sampling points. To obtain accurate measurement results, a large number of measurement points need to be taken. The measurement method is cumbersome and inefficient, and is not suitable for High-volume, flexible measurement requirements in workshops and assembly sites

Embodiment Construction

[0044] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0045] The invention will be described in detail below with reference to the accompanying drawings and examples.

[0046] A countersunk angle gauge for countersunk holes, which includes a dial indicator 6, a sleeve 2, a positioning screw 3 and a gauge head 1;

[0047]The sleeve 2 includes a hollow chamber, which is a sleeve cavity 21;

[0048] The gauge head 1 is placed at the bottom of the sleeve cavity 21 and is slidably fitted therewith. The bottom 12 of the gauge head performs telescopic movement relative to the bottom surface of the sleeve 2. When the bottom surface of the gauge head 1 is in contact with the When the bottom surface of the sleeve 2 is at the same level, the measuring head 61 of the dial indicator 6 abuts against the top 11 of the measuring head of the gauge and the measuring head 61 is ...

Abstract

The invention provides a countersunk head angle gauge for a counterbore and a measurement method of the countersunk head angle gauge. The countersunk head angle gauge comprises a dial indicator, a sleeve and a gauge measuring head, wherein the sleeve comprises a hollow cavity; the cavity refers to a sleeve cavity; the gauge measuring head is arranged at the bottom of the sleeve cavity and is in sliding fit with the sleeve cavity; the bottom of the gauge measuring head does a telescopic motion relative to the bottom surface of the sleeve; and when the bottom surface of the gauge measuring head and the bottom surface of the sleeve are positioned on the same horizontal plane, a measuring head of the dial indicator is pressed against the top of the gauge measuring head, and the measuring head is positioned in a compressed state. According to the matched arrangement of the dial indicator, the sleeve and the gauge measuring head, the direct measurement of the countersunk head angle can be converted into length measurement, the efficiency of measuring the countersunk head angle is improved by using the countersunk head angle gauge, and the measurement accuracy is improved.

Description

technical field [0001] The invention belongs to the field of countersink angle measurement, and in particular relates to a countersink angle gauge and a measuring method thereof. Background technique [0002] A large category of aerospace fasteners is countersunk head fasteners, such as countersunk head bolts, countersunk head rivets, etc. These fasteners need to be installed and tested in the production and acceptance process. During the process and the test, a large number of mounting plates and test fixtures with countersunk holes are required. Whether the size of the countersunk hole (especially the angle of the countersunk hole) is qualified or not directly affects the use effect and detection of countersunk head fasteners. As a result, the detection of the size of countersink parts is very important. [0003] The main difficulty in the production and measurement of countersunk parts lies in the measurement of the countersunk angle. Due to the small space and the diffi...
