Description

Technical Field

[0001] The utility model belongs to the technical field of motor auxiliary processing, and in particular relates to a motor rotor sheet stacking device. Background Art

[0002] The motor rotor is the rotating part inside the motor that is responsible for converting energy and outputting mechanical work. It is composed of multiple key components, including the rotor core, shaft, and commutator. The motor core is usually made of silicon steel sheets because silicon steel sheets have good magnetic conductivity and low iron loss (including hysteresis loss and eddy current loss). In the motor, the stator core and rotor core, and the air gap between the stator and the rotor together constitute the complete magnetic circuit of the motor, and the rotor core is composed of multiple rotor sheets.

[0003] In the prior art, rotor sheets (silicon steel sheets) are usually processed by cold rolling and hot rolling. After processing, the rotor sheets need to be neatly stacked and welded. However, the rolled rotor sheets are stored in storage boxes and need to be neatly stacked by workers before welding. When there are many stacked rotor sheets, the stacking process is time-consuming and labor-intensive due to their heavy weight, and has poor adaptability and practicality. Utility Model Content

[0029] Please also read Figures 1 to 3 , the motor rotor sheet stacking device provided by the utility model is now described. The motor rotor sheet stacking device comprises: a rotating seat 10, a limiting cylinder 20 and a stacking mechanism 30. The rotating seat 10 has a rotating portion whose axis is arranged in the vertical direction. A limiting column 11 for inserting into the center hole of each motor rotor sheet is coaxially arranged on the rotating seat 10. The limiting cylinder 20 is arranged on the rotating seat 10 and sleeved on the rotating portion. The limiting cylinder 20 has a cylinder cavity, and the axis of the cylinder cavity is arranged colinearly with the axis of the rotating seat 10. The stacking mechanism 30 is arranged at the top of the limiting cylinder 20, and has an adjustment end arranged in the vertical direction and can be lifted and lowered. The stacking mechanism 30 is used to make the adjustment end move downward from the top rotor sheet in sequence during the rotation of each rotor sheet, and pass through the winding grooves on each rotor sheet to neatly stack each motor rotor sheet.

[0030] Compared with the prior art, the motor rotor sheet stacking device provided in this embodiment is provided with a rotating seat 10, which can be inserted into the center hole of each motor rotor sheet through the limiting column 11 on the rotating seat 10, and drive each motor rotor sheet to rotate through the rotating part. A limiting cylinder 20 is provided, which can be sleeved on the rotating part to limit the motor rotor sheets in the cylinder cavity. A stacking mechanism 30 is provided, which can be provided at the top of the limiting cylinder 20 and arranged in the vertical direction and can be lifted and lowered. The adjusting end moves downward from the top rotor sheet in sequence during the rotation of each rotor sheet, and passes through the winding grooves on each rotor sheet to neatly stack each motor rotor sheet.

[0031] In some embodiments, the rotating seat 10 may be used as follows: Figures 1 to 3 See the structure shown. Figures 1 to 3The rotating seat 10 includes: a base 12, a rotating disk 13 and a driver 14. The base 12 is arranged horizontally. The rotating disk 13 is rotatably arranged on the base 12, and the rotating axis is arranged in the vertical direction. The driver 14 is used to drive the rotating disk 13 to rotate.

[0032] The base 12 can be understood as a pedestal set on the ground, which is used to fix the motor rotor sheet stacking device. The rotating disk 13 can be rotatably set on the base 12. The upper surface of the rotating disk 13 is provided with a rubber layer. The rubber layer can increase the friction between the rotating disk 13 and the motor rotor sheet when the rotating disk 13 rotates. The driver 14 can drive the rotating disk 13 to rotate. The rotating disk 13 is the rotating part. The limit column 11 and the rotating disk 13 can be understood as an integral connection.
