Technical Field

[0001] The invention belongs to the technical field of motor production, and specifically refers to a motor rotor core shaft insertion device. Background Art

It can only insert the shaft of a single specification of core, and has a low scope of application.

[0004] Therefore, a motor rotor core shaft insertion device is needed to solve the technical problems in the prior art of the rotor shaft extending far from the rotor core and the inability to ensure coaxiality. Summary of the invention

[0011] The beneficial effects achieved by the present invention using the above structure are as follows:

[0012] 1. The present application utilizes a first hydraulic telescopic rod to drive the moving plate to move, and drives the moving push assembly to move. The moving push assembly cooperates with the pressure-type iron core fixing group, and utilizes the contact and cooperation of the upper contact block and the lower contact block to drive the fixed rack to engage the fixed gear, so as to fix the motor rotor cores of different sizes, and ensure the accuracy of the shaft insertion process. During the movement of the moving plate, the motor rotor shaft contacts the swing claw, and the motor rotor shaft is clamped and fixed by swinging on the support column, so as to ensure the coaxial arrangement of the motor rotor shaft and the motor rotor core. As the motor rotor shaft is inserted, the distance of the motor rotor shaft extending out of the motor rotor core is detected, and the distance accuracy during the shaft insertion process is ensured.

[0013] 2. The cooperation between the pressure-type shaft end fixing component and the movable pushing component realizes the fixing of the motor rotor core. The upper contact block moves, the upper contact block contacts the lower contact block, pushes the fixed rack to engage the fixed gear, drives the plane thread to drive the moving block to move centripetally, fixes the motor rotor core, and after the fixing is completed, compresses the extrusion spring to continuously fix the motor rotor core to avoid clamping the motor rotor core;

[0014] 3. Fix the motor rotor shaft through the pressure-type shaft end fixing assembly, preset the motor rotor shaft on the motor rotor core, and the motor rotor shaft contacts the swing claw. As the moving plate continues to approach the motor rotor core, the motor rotor shaft drives the swing claw to swing on the support column, presenting an inner grasping mode, and continuously fixes the motor rotor shaft. The tension spring pulls the swing claw, and after the shaft is inserted, it drives the swing claw to reset so that it can be fixed next time;

[0015] 4. The cooperation between the pressure-type shaft end fixing component and the pressure-type iron core fixing component ensures the coaxiality. The swing claws with three claws coaxially fix the motor rotor shaft, and the fixing plate with three equal parts coaxially fixes the motor rotor core. The first hydraulic telescopic rod drives the moving plate to press down. When the motor rotor core is inserted into the shaft, the coaxial accuracy of the motor rotor core and the motor rotor shaft is ensured.

[0016] 5. As the motor rotor shaft is inserted, the position detection component detects the distance that the motor rotor shaft extends out of the motor rotor core. When the shaft end of the motor rotor shaft drives the lower contact plate to move and contacts the lower contact switch, the shaft end position of the motor rotor shaft is determined. The upper contact plate is fixedly connected to the fixed shell and contacts the upper contact switch to determine the position of one end of the motor rotor core and the distance that the motor rotor shaft extends out of the motor rotor core. The second hydraulic telescopic rod is used to drive the driving plate and the adjustment plate to move, and the lower contact switch is driven to move. According to different motor specifications, the distance that the motor rotor shaft extends out of the motor rotor core is adjusted. BRIEF DESCRIPTION OF THE DRAWINGS
