Description

Technical Field

[0001] This utility model relates to the field of automated assembly technology, and in particular to a rotor runout detection mechanism. Background Technology

[0002] In fields such as motor manufacturing, precision instrument assembly, and rotor dynamic balancing testing, rotor runout is a key indicator for measuring its rotational accuracy and operational stability. Traditional runout testing methods often involve manual point-by-point measurements using handheld dial indicators or contact measuring instruments. This process is cumbersome, inefficient, and prone to measurement errors due to human factors. While some semi-automatic testing equipment can achieve rotational drive, it typically relies on clamping mechanisms or friction wheels directly pressing against the rotor surface, easily causing scratches or indentations on the rotor's outer wall, making it particularly unsuitable for precision rotors with high surface accuracy requirements. Furthermore, existing equipment often struggles to ensure shaft alignment during rotor clamping and positioning, leading to measurement reference deviations and affecting data accuracy. Therefore, there is an urgent need for an automated rotor runout testing mechanism that can achieve rapid positioning, non-destructive drive, and high detection accuracy. Utility Model Content

[0003] The main purpose of this invention is to propose a rotor runout detection mechanism, which aims to provide an automated rotor runout detection mechanism with fast positioning, non-destructive driving and high detection accuracy.

[0004] To achieve the above objectives, this utility model proposes a rotor runout detection mechanism, including a frame, a material platform disposed on the frame for supporting the rotor, a pair of ejector pins, and a lifting platform;

[0005] The material platform is provided with two slots at intervals. The two slots are used to support the two exposed ends of the rotor shaft so that the rotor is suspended in the air.

[0006] The two ejector pins are respectively placed on the left and right sides of the material table, for moving towards each other and respectively pressing against the center of both ends of the rotating shaft to position the rotor. A first driving mechanism is provided to drive the two ejector pins to move towards each other.

[0007] The lifting platform can move up and down relative to the frame. The lifting platform is equipped with a rolling belt driven by a power device. The lifting platform can drive the rolling belt down to contact the outer peripheral wall of the suspended rotor and form a rolling engagement.

[0008] When the rolling belt is running, the rotor can be driven to rotate around the axis of the shaft by friction.

[0009] It also includes detection sensors located on the frame for collecting and analyzing rotor runout data as the rotor rotates.

[0010] Preferably, both ejector pins are movably mounted on the frame, and each ejector pin is connected to a first drive mechanism;

[0011] Alternatively, one of the two ejector pins may be fixedly mounted to the frame, while the other may be movably mounted to the frame and connected to the first drive mechanism.

[0012] Preferably, the detection sensor includes a radial runout sensor and an axial runout sensor.

[0013] Preferably, the bracket is V-shaped.

[0014] Preferably, the lifting platform is movably assembled to the frame via a slide rail and a slide groove, and is driven by a second drive mechanism to achieve lifting movement.

[0015] Preferably, the frame is also equipped with a through-beam sensor for sensing whether there is material on the material platform.

[0016] Preferably, the material platform includes a first moving member and a second moving member arranged at left and right intervals, the two support slots are respectively disposed on the top of the first moving member and the second moving member, and the rotor is suspended between the first moving member and the second moving member.

[0017] Preferably, both the first and second moving parts are movably assembled to the frame via a sliding structure and can move close to or away from each other.

[0018] Preferably, it also includes a first locking member and a second locking member;

[0019] The first locking member is screwed onto the first moving member, and the first moving member can be locked or unlocked from the frame by rotating the first locking member;

[0020] The second locking member is screwed onto the second moving member, and the second moving member can be locked or unlocked from the frame by rotating the second locking member.

[0021] Preferably, the first drive mechanism and the second drive mechanism are linear motors or cylinders.

[0022] This invention achieves suspended support for the rotor by setting a material platform with two slots. Combined with a pair of opposing ejector pins, it can quickly and accurately center the two ends of the rotor shaft, effectively avoiding measurement errors caused by clamping eccentricity. The lifting platform drives the rolling belt to descend and contact the outer peripheral wall of the rotor, using friction to drive the rotor to rotate. This eliminates the need for direct clamping or contact with the rotor's critical surfaces, avoiding scratches or deformation, and is especially suitable for precision rotors with high surface quality requirements. The entire testing process can be automated, significantly improving testing efficiency and consistency. At the same time, the sensor collects and analyzes the fluctuation data in real time, improving the reliability and repeatability of the data, and has good engineering application value.
