Description

Technical Field

[0001] The invention relates to the technical field of motor press-fitting equipment, and in particular to a three-phase asynchronous motor rotor core shaft press-fitting device. Background Art

[0002] When processing the rotor in a three-phase asynchronous motor, the mandrel needs to be pressed into the iron core to form a complete rotor. The existing pressing equipment first clamps the mandrel when in use, and then pushes the mandrel into the iron core through a hydraulic press.

[0003] However, the end face area of ​​the mandrel is small. During press-fitting, the contact area between the mandrel and the pressing plate is small, which makes it easy for the force to be uneven, resulting in an inclination in the direction of pressure, thus affecting the press-fitting effect.

When the calibration mechanism moves to the bottom of the pressing mechanism, the motor stops and the pressing mechanism performs pressing. After the pressing is completed, the motor drives the bottom plate to move to the side of the driven gear, and unloading can be carried out. Then the motor rotates in the opposite direction to make the bottom plate return to the side of the motor so that it can be loaded again.

[0011] Specifically, the first calibration mechanism includes a base fixed on the bottom plate, a third spring telescopic rod fixed on the base, a limit plate fixed on the third spring telescopic rod, a through slot fixed on the third limit plate, a sixth clamping assembly fixed on the limit plate, a placement slot fixed on the base, and a second calibration assembly rotatably arranged on the base.

[0014] Specifically, the iron core clamping device includes a second gear ring rotatably arranged on a base, a plurality of third racks slidably arranged on the base and meshing with the second gear ring, and a first clamping seat fixedly arranged on the third rack.

An Archimedean spiral groove is arranged on the surface of the third gear ring that contacts the fourth rack, and the fourth rack meshes with the Archimedean spiral groove on the third gear ring. When the third gear ring rotates, it drives the fourth rack to move, and then drives the second clamping seat to move; the second clamping seat is used to limit the spindle.

[0016] Specifically, the first clutch device includes a first clutch groove fixed on the first gear ring, a fifth slide groove fixed on the second gear ring, and a first clutch block slidably arranged on the fifth slide groove; the first clutch block and the second gear ring are connected by a fourth spring.

The rotation of the first gear ring can drive the second gear ring to rotate together, and then drive the first clamping seat to move. When the first clamping seat contacts the iron core, the iron core will apply a force to the first clamping seat, so that the first clamping seat cannot continue to move, that is, the second gear ring cannot continue to rotate, and the first gear ring will continue to rotate under the drive of the first gear, so that the first clutch groove squeezes the first clutch block, so that the first clutch block slides into the fifth sliding groove, and the fourth spring is compressed. At this time, the first gear ring is disconnected from the second gear ring, the second gear ring will not rotate, and the first gear ring can continue to drive the third gear ring to rotate; when the first gear ring contacts the second rack, the second gear ring will drive the first gear ring to rotate in the opposite direction, that is, drive the second gear ring to rotate in the opposite direction, so that the first clamping seat is away from the iron core and the clamping is released.

The second clutch block is provided with an inclined surface. In the initial state, the second clutch block cooperates with the second clutch groove. The rotation of the first gear ring can drive the third gear ring to rotate together, thereby driving the second clamping seat to move. When the second clamping seat contacts the mandrel, the mandrel will apply a force to the second clamping seat, so that the second clamping seat cannot continue to move, that is, the third gear ring cannot continue to rotate, and the first gear ring will continue to rotate under the drive of the first gear, so that the second clutch groove squeezes the second clutch block, so that the second clutch block slides into the sixth slide groove, and the fifth spring is compressed. At this time, the first gear ring is disconnected from the third gear ring; when the first gear ring contacts the second rack, the second gear will drive the first gear ring to rotate in the opposite direction, that is, drive the third gear ring to rotate in the opposite direction, so that the second clamping seat is away from the mandrel and the limit is released.

[0018] The beneficial effects of the present invention are:

[0019] (1) The first clamping assembly to the fourth clamping assembly are provided on the first pressing plate, which can clamp the mandrel from four directions, and at the same time increase the pressure area during press-fitting, thereby solving the problem of uneven pressure in the existing press-fitting device.

[0020] (2) A plurality of rotating devices are provided. When the core shaft is clamped, the first slider slides on the second slide groove, and the second spring telescopic rod rotates with the contact point between the first clamping head and the core shaft as a fulcrum, so that the first slider slides on the second slide groove. The friction between the first clamping head and the core shaft is static friction. Compared with the relative sliding of the first clamping head and the core shaft, the static friction will be smaller than the sliding friction, thereby achieving the function of reducing friction.

[0021] (3) The second calibration component can clamp the iron core and the core shaft at the same time. The iron core clamping device and the core shaft clamping device are synchronously driven through the first ring gear, so that the first clamping seat and the second clamping seat move simultaneously, and finally the iron core and the core shaft are located on the same axis.

[0022] (4) Since the axis of the core shaft and the first pressure plate are not necessarily the same, the compression degrees of the second spring telescopic rods on all sides are different. After frequent use, the wear of each second spring telescopic rod is likely to be different, resulting in a reduction in the clamping effect. The rotating assembly can rotate when the first pressure plate moves downward, driving the second spring telescopic rods to rotate together. Even if the axis of the core shaft is offset, the second spring telescopic rods on all sides can rotate from the side with less compression to the side with more compression, or from the side with more compression to the side with less compression during the rotation process. In this way, the wear degrees of each second spring telescopic rod can be more uniform, avoiding excessive wear of the second spring telescopic rod on one side, which leads to a reduction in the clamping limit effect.
