Device for measuring spatial position of knuckle bearing

Abstract

The invention relates to a device for measuring the spatial position of a knuckle bearing, which comprises a measuring joint main body and a powerful magnet, and is characterized in that the measuring joint main body comprises a first measuring component and a second measuring component, and the first measuring component and the second measuring component are separably assembled together; the joint bearing and the joint lug are clamped between the first measuring component and the second measuring component; the left side and the right side of the measuring connector body are further provided with symmetrically-arranged counter bores, the counter bores on the left side and the right side are coaxial with a knuckle bearing clamped between the first measuring component and the second measuring component, and the bottoms of the counter bores are provided with the powerful magnets so that an optical measuring target of the laser tracker can be attracted. Therefore, the spatial position of the knuckle bearing is measured. The device has the advantages of few components, extremely small accumulated tolerance, high measurement precision, simple structure, simplicity, convenience and rapidness in installation and operation, easiness in production and processing, low cost, and facilitation of implementation of mass production and popularization and application.

Description

technical field [0001] The invention belongs to the technical field of aircraft component measurement, in particular to a device for space position measurement of joint bearings. Background technique [0002] Joint bearings are commonly used parts of many mechanical products, especially large parts of aircraft structures. When large parts of aircraft are docked, it is necessary to give priority to ensuring the accuracy of their spatial positions. Since joint bearings can rotate freely under normal conditions, general measurement methods cannot be accurately measured. The position of the center of the ball and the axis of the hole of the joint installed with the joint bearing, the joint installed with the joint bearing is generally a key structure, and is the main force transmission component such as an aircraft, and its position accuracy directly affects the installation accuracy and force transmission effect of the corresponding component .

[0002] Joint bearings are commonly used parts of many mechanical products, especially large parts of aircraft structures. When large parts of aircraft are docked, it is necessary to give priority to ensuring the accuracy of their spatial positions. Since joint bearings can rotate freely under normal conditions, general measurement methods cannot be accurately measured. The position of the center of the ball and the axis of the hole of the joint installed with the joint bearing, the joint installed with the joint bearing is generally a key structure, and is the main force transmission component such as an aircraft, and its position accuracy directly affects the installation accuracy and force transmission effect of the corresponding component

[0003] However, the applicant found that: currently, the position measurement of the joint bearing in space is generally carried out using a laser tracker; when measuring, it is necessary to first install an adapter bushing on the joint bearing, then install an optical measurement adapter seat on the bush, and finally install the adapter bushing on the bushing. The optical measurement target is placed on the adapter base. This method requires many accessories, the accumulation of tolerance is large, the measurement accuracy is not high, and the installation is troublesome and time-consuming.
