Description

Technical Field

[0001] The utility model relates to the technical field of rotor testing, and specifically relates to a device for offset and angle adjustment and locking between two shaft segments. Background Technique

[0002] The rotor is a key component in many mechanical devices and usually has a rotationally symmetric structure. Measuring the rotor during the production process can timely detect potential quality problems and avoid equipment damage or even safety accidents caused by rotor failures. The detection between multiple rotors is mainly to ensure that multiple rotors can operate coordinately and stably in the system, and at the same time timely detect potential problems to ensure the reliability and safety of the system. Usually, there are phase relationship detection and motion coordination detection. The phase relationship detection is to use a phase sensor to detect the phase angles of each rotor to determine their relative position relationship, and the motion coordination detection is to observe the motion trajectories between the rotors to check whether there is a risk of interference or collision.

[0003] Chinese Patent CN214506841U proposes a dynamic balance testing machine for facilitating clamping in motor rotor detection, including a base and a bracket. A support is arranged on the left side of the upper end of the base, and a dynamic balance instrument is arranged on the front surface of the support. A driving device is arranged in the middle of the upper end of the support, and a coupling frame is arranged at the right end of the driving device.

Bolts are arranged on both sides of the bottom of the bracket, and a bearing is arranged in the middle of the top of the bracket. By vertically placing the required bearing into the placement groove at the upper end of the bracket, the connection between the abutting frame and the placement groove is a threaded connection, and then the abutting frame is screwed clockwise until the front end abuts against the surface of the bearing, so that the abutting frame tightly abuts the bearing, thereby effectively clamping and fixing the bearing and reducing the shaking of the bearing.

[0004] However, the technical solution of this patent has the following problems:

[0005] 1. This patent vertically places the required bearing into the placement groove at the upper end of the bracket, the connection between the abutting frame and the placement groove is a threaded connection, and then the abutting frame is screwed clockwise until the front end abuts against the surface of the bearing, so that the abutting frame tightly abuts the bearing, thereby effectively clamping and fixing the bearing and reducing the shaking of the bearing.
