Description

Technical Field

[0001] This utility model relates to the field of unmanned vertical take-off and landing aircraft, specifically to an eVTOL aircraft motor assembly fixture. Background Technology

[0002] As one of the core components of an eVTOL aircraft, the motor's main function is to generate power, enabling the aircraft to take off vertically, hover, and land. The design and performance of the motor directly affect the overall efficiency, safety, and economy of the aircraft.

[0003] eVTOL motors also have relatively strict requirements regarding coaxiality, strength, rigidity, and weight. Currently, during assembly, the motor stator and rotor attract each other, generating a strong suction force. This can cause damage to the stator and rotor due to collisions, or even injury to workers. Because of this suction force, it is difficult for operators to control the coaxiality of the motor stator and rotor during installation and testing, and it is also difficult to control and inspect the gap between them.

[0004] Therefore, to solve the above problems, an eVTOL aircraft motor assembly fixture is needed to address these issues. Utility Model Content

[0005] In view of this, the motor assembly fixture of this technical solution has the positioning sleeve sleeve installed on the adjusting rod. The adjusting rod rotates and moves in the axial direction, driving the rotor mounting assembly to move synchronously, thereby realizing the adjustment of the distance between the rotor and the stator. The fixture has a high degree of integration, simple structure and convenient operation, and ensures the coaxiality of the stator and rotor installation.

[0006] An eVTOL aircraft motor assembly fixture includes a base, an adjusting rod rotatably mounted on the base, a positioning sleeve sleeved on the adjusting rod and connected to the base, a stator mounting assembly that is fitted with the positioning sleeve, and a rotor mounting assembly that is fitted with the positioning sleeve. The end of the adjusting rod is rotatably mounted with the rotor mounting assembly, and the rotation of the adjusting rod drives the rotor mounting assembly to move along the axial direction of the positioning sleeve.

[0007] Furthermore, a nut sleeve for use with an adjusting rod is installed on the side of the base. The adjusting rod is installed with the nut sleeve and passes through the base to form a screw-nut pair for use.

[0008] Furthermore, the rotor mounting assembly includes a rotor mounting sleeve fitted onto the positioning sleeve, a rotor limiting sleeve fixedly mounted in conjunction with the rotor mounting sleeve, and a limiting bearing disposed at the end of the rotor mounting sleeve. The end of the adjusting rod is rotatably mounted in conjunction with the limiting bearing, and the rotation of the adjusting rod along the axial direction causes the rotor mounting sleeve to move synchronously along the axial direction.

[0009] Furthermore, a limit retaining ring is provided at the end of the rotor limiting sleeve, and a bearing retaining ring is provided at the end of the adjusting rod to cooperate with the limiting bearing.

[0010] Furthermore, the positioning sleeve has a sleeve positioning disc that is fixedly installed on the base in the radial direction, and the base is provided with a clamp installation assembly that is limited to the end of the positioning sleeve.

[0011] Furthermore, the stator mounting assembly includes a stator mounting plate fitted onto a positioning sleeve and a support arm, the end of which is fixedly mounted to the base.

[0012] Furthermore, the support arm consists of multiple arms that are evenly distributed and installed on the end face of the stator mounting plate.

[0014] The beneficial effects of this utility model are: the motor assembly fixture of this technical solution has a positioning sleeve sleeve installed on the adjusting rod.
