Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of motor life testing equipment, and specifically relates to a motor life testing fixture. Background Technology
[0002] Current motor life testing fixtures cannot meet the requirements for life testing of finite torque motors at multiple shaft extension positions. Specifically, when used in aircraft, finite torque motors need to adapt to different flight conditions, such as the pull-up angle during takeoff, level flight, and the dive angle during landing. Therefore, motor life testing needs to be conducted at five positions: horizontal, vertically upward, vertically downward, 45° upward, and 45° downward. However, current motor life testing fixtures typically only allow testing in the horizontal direction, failing to meet this multi-angle testing requirement. This results in an inability to comprehensively evaluate the motor's performance and lifespan in actual operating environments, thus affecting the accuracy of motor life testing.

[0019] Example 1: This embodiment discloses a motor life testing fixture. A top view of the motor life testing fixture of this utility model is shown below. Figure 1 As shown, the technical solution of this utility model is specifically described as follows: The motor life test fixture in this embodiment includes a bracket 1 (in this embodiment, the bracket 1 is an aluminum alloy bracket, which not only has good corrosion resistance but also can withstand large loads) and a sleeve 2 (in this embodiment, the sleeve 2 is an aluminum alloy sleeve, which not only has good corrosion resistance but also is lightweight, making it easy to install and disassemble. In this embodiment, the sleeve 2 is a cylindrical sleeve that matches the shape of the motor 5 to be tested. The cylindrical sleeve not only distributes the force evenly but also has good compressive and bending resistance).
[0020] The sleeve 2 is detachably mounted on the bracket 1 via the second connector (in this embodiment, the second connector is a screw rod, which passes through the second through hole 10 and the third through hole 11). The mounting surfaces of the sleeve 2 and the bracket 1 are inclined, and the inclination angle is equal to the test angle of the motor 5 to be tested (in this embodiment, the inclination angle is 30°-60°, and the inclination angle can be selected according to actual needs).
[0021] Sleeve 2 has a hollow structure, and its interior is used to house and fix the motor 5 to be tested. Sleeve 2 has a through hole (…). Figure 1 The first through hole 3 (with a diameter of 20mm) is used for the extension of the shaft of the motor to be tested. The sleeve 2 and the motor 5 to be tested are connected by a first connector (in this embodiment, the first connector is a screw hole (the screw hole is in...) Figure 1The mounting hole 4 is used to indicate the screw holes. In this embodiment, the screw holes are specifically the first screw hole 6, the second screw hole 7, the third screw hole 8, and the fourth screw hole 9 (in this embodiment, the screw holes are circular). Screw hole connections typically use standard fasteners such as bolts and screws, which are not only simple and convenient to install, but also easy to disassemble and maintain.
[0022] The following is a detailed description of the motor life testing fixture of this utility model, extending from five directions along the shaft: A. The shaft of the motor under test extends horizontally. When the shaft extends horizontally, only sleeve 2 is needed to test the motor's lifespan. Sleeve 2 is machined into flat surfaces on both sides, and the structural diagram with the shaft extending horizontally is shown below. Figure 2 As shown.
[0023] B. The shaft of the motor to be tested extends vertically upwards. When the shaft extends vertically upwards, only sleeve 2 is needed to test the motor's lifespan. Rotating sleeve 2 90° clockwise, the shaft of the motor 5 under test extends vertically upwards. A schematic diagram of this vertically upward-extending shaft is shown below. Figure 3 As shown.
[0024] C. The shaft of the motor under test extends vertically downwards. When the shaft extends vertically downwards, only sleeve 2 is needed to test the motor's lifespan. Rotating sleeve 2 counterclockwise by 90°, a hollow pad 12 is placed below sleeve 2 to prevent direct contact between the motor 5 under test and the test platform, ensuring the accuracy and safety of the test. At this time, the shaft of the motor 5 under test extends vertically downwards. A schematic diagram of this vertically downward-extending structure is shown below. Figure 4 As shown.

[0026] E. The shaft of the motor under test extends downwards at a 45° angle. When the shaft extends downwards at a 45° angle, sleeve 2 and bracket 1 are needed to test the motor's lifespan. A schematic diagram of the structure with the shaft extending downwards at a 45° angle is shown below. Figure 6 As shown.
[0027] In this embodiment, the motor 5 to be tested can be any motor with angle requirements, such as a finite angle torque motor.
[0028] This utility model uses a bracket 5 with an inclined angle (the sleeve 2 is detachably installed on the bracket 1, and the mounting surface of the sleeve 2 is inclined to the bracket 1) and the sleeve 2 to realize the life test of the motor at 5 different angle positions, which comprehensively covers the actual operating conditions of the motor on the aircraft and has good versatility.

In this embodiment, the sleeve 2 is a cylindrical sleeve that matches the shape of the motor 5 to be tested. The cylindrical sleeve not only distributes the force evenly but also has good compressive and bending resistance).
[0030] The sleeve 2 is detachably mounted on the bracket 1 via the second connector (in this embodiment, the second connector is a screw rod, which passes through the second through hole 10 and the third through hole 11). The mounting surfaces of the sleeve 2 and the bracket 1 are inclined, and the inclination angle is equal to the test angle of the motor 5 to be tested (in this embodiment, the inclination angle is 30°-60°, and the inclination angle can be selected according to actual needs).
[0031] Sleeve 2 has a hollow structure, and its interior is used to house and fix the motor 5 to be tested. Sleeve 2 has a through hole (…).

Figure 1 The mounting hole 4 is used to indicate the screw holes. In this embodiment, the screw holes are specifically the first screw hole 6, the second screw hole 7, the third screw hole 8, and the fourth screw hole 9. In this embodiment, the screw holes are oblong screw holes. Screw hole connections typically use standard fasteners such as bolts and screws, which are not only simple and convenient to install, but also easy to disassemble and maintain.
