Description

Technical Field

[0001] The utility model relates to the field of motor processing equipment, and more specifically, to a motor rotor detection auxiliary device. Background Art

[0002] After the motor rotor is machined, it is necessary to inspect the surface of the motor rotor, especially the surface of the rotor core, to confirm whether there are any defects on the rotor surface. Currently, motor rotor surface inspection is mainly done manually, but manual inspection is inefficient, especially for motor rotors of larger sizes. Inspectors need to use a ladder to conduct the inspection. Moreover, when the motor rotor is lying flat, it needs to be flipped during the inspection process, which can easily cause damage to the motor rotor surface. This makes the inspection process time-consuming and labor-intensive, and directly results in low motor rotor surface inspection efficiency. Summary of the Invention

[0044] Figure 1-Figure 2 An embodiment of the present invention provides a motor rotor detection auxiliary device, comprising:

[0045] A workbench 1, the upper end of which is provided with a lifting mechanism;

[0046] a rotor supporting mechanism, which is in transmission connection with the lifting mechanism;

[0047] Two movable brackets 2, which are respectively arranged on both sides of the rotor support mechanism and are slidably connected to the workbench 1;

[0048] Two sets of rotor clamping mechanisms, which are rotatably arranged on the movable bracket 2;

[0049] A rotation drive mechanism, which is provided on one of the movable supports 2 and is in transmission connection with the corresponding rotor clamping mechanism;

[0050] a linear drive mechanism, which is in transmission connection with the two movable supports 2 to drive the two movable supports 2 to move closer to or away from each other;

[0051] Two sets of camera mechanisms 3 are respectively arranged on both sides of the rotor support mechanism and connected to the workbench 1 through a moving mechanism.

[0052] In this embodiment, the two movable supports 2 are initially moved away from each other to their limit positions. Simultaneously, the movable mechanism also drives the camera mechanism 3 outward, facilitating the horizontal hoisting of the motor rotor above the rotor support mechanism. The lifting mechanism drives the rotor support mechanism upward to the target position, and then the rotor core portion of the motor rotor is placed on the rotor support mechanism. At this point, the rotor shaft of the motor rotor matches the height of the two sets of rotor clamping mechanisms, and the distances between the two ends of the rotor shaft and the two sets of rotor clamping mechanisms are equal. The linear drive mechanism then drives the two movable supports 2 toward each other, connecting them to both ends of the rotor shaft. The lifting mechanism then drives the rotor support mechanism downward until it separates from the motor rotor. The movable mechanism then drives the camera mechanism 3 inward, adjusting its height so that it is close to the rotor core. This completes the chain structure of the motor rotor. The rotary drive mechanism drives the motor rotor to rotate, using a stepping method, each time rotating a fixed angle. An inspector standing on one side of the rotor can inspect the rotor's appearance. At the same time, the appearance photos of the rotor core part can be obtained through the camera unit 3. The camera unit 3 is connected to the client or the host computer through the wireless transmission module to take photos of the rotor core part for later tracing or remote re-inspection.

[0066] A plurality of positioning bolts 12 are threadedly installed in each of the threaded through holes.

[0067] In this embodiment, the inner diameter of the positioning groove is the same as the outer diameter of the rotor shaft end. The rotor shaft end is inserted into the positioning groove, and then the positioning bolt 12 is tightened to secure the rotor shaft end. To prevent the positioning bolt 12 from damaging the rotor shaft surface, a rubber pad can be placed at the end of the positioning bolt 12.
