Description

Technical Field

[0001] The present application relates to the technical field of motor processing equipment, and in particular to an automatic assembly equipment for a motor stator and rotor. Background Art

[0002] The motor rotor and motor stator are the two main parts in an electric motor; the motor rotor, also known as the armature, is the rotating part of the motor. It usually includes a shaft and a conductive coil or conductor mounted on the shaft. When current passes through the conductive coil of the rotor, the rotor will be subjected to a torque due to the action of electromagnetic force, thereby starting to rotate. The design and material of the rotor have an important influence on the performance and efficiency of the motor.

[0003] The prior art discloses an assembly device for a motor rotor and stator, which includes a mounting platform, a load plate is slidably connected to the mounting platform, and both left and right ends of the load plate pass through the mounting platform, a stator fixing device is provided on the mounting platform and is located between the left and right ends of the load plate, the right end of the load plate is connected to a base, a centering ring sleeve matched with the rotor is fixed on the left end surface of the base, a lead screw is installed on the left end of the load plate, the left end of the lead screw is matched with a nut rotatably connected to the load plate, and the right end is fixed with a top block that can be pressed against the rotor, the nut is connected with a power mechanism that drives itself to rotate, and the bottom of the load plate is matched with a long lead screw arranged along its own sliding direction, and the long lead screw is connected with a motor fixed on the mounting platform.

[0004] With regard to the above-mentioned related technologies, when assembling the stator and the rotor, the stator is first fixed, and then one end of the rotating shaft on the rotor is clamped and fixed on the centering ring sleeve, and then the centering ring sleeve and the rotor are driven by the base to move toward the stator side to complete the assembly. When the rotor enters the inner cavity of the stator, it will be attracted by the magnetic attraction of the stator. However, by fixing the rotating shaft on one side, the rotating shaft is affected by both the magnetic attraction force and the gravity of the rotor itself, resulting in a high possibility that the rotating shaft will bend and deform and cannot smoothly pass through the bearing hole on the stator. It is necessary to realign the rotating shaft or fine-tune the rotor's posture, which affects the assembly efficiency of the motor stator and rotor. Summary of the invention

[0006] The present application provides a motor stator and rotor automatic assembly device adopts the following technical solution: An automatic assembly device for a motor stator and rotor, comprising A placement seat with a clearance hole; A plurality of arc-shaped mounting plates, wherein the plurality of arc-shaped mounting plates are coaxially arranged, the arc-shaped mounting plates are located above the placement seat, and the arc-shaped mounting plates are rotatably connected to a plurality of abutting balls on opposite sides, and the abutting balls on the two sides form two contact surfaces; A fixing ring, the fixing ring is coaxially connected to the arc-shaped mounting plate, and the fixing ring is located above the placement seat; An adjusting unit is used for changing the distance between the placing seat and the fixing ring, wherein the adjusting unit is connected to the placing seat, and the adjusting unit is connected to the fixing ring.

[0007] By adopting the above technical solution, the fixing ring is first moved away from the placement seat through the adjustment unit, and the movement of the fixing ring drives the arc-shaped mounting plate to move toward the side away from the placement seat until the distance between the arc-shaped mounting plate and the placement seat is large enough for the stator to pass through, and the stator is fixed on the placement seat. Then, the fixing ring is driven to move by the adjustment unit again, so that the arc-shaped mounting plate drives the abutting balls to extend into the inner cavity of the stator, and the outer contact surface formed by the abutting balls is rollingly connected with the inner cavity wall of the stator. Then, force is applied to the rotor, so that the rotor extends into the inner cavity of the stator. At the same time, the inner contact surface formed by the rotor and the abutting balls is rollingly connected with the outer wall of the rotor, so as to support the rotor and avoid the rotating bearing on the rotor being affected by the magnetic attraction between the rotor and the stator. Excessive bending moment causes deformation; the designed motor stator and rotor automatic assembly equipment can fix the position of the stator through the placement seat, and can use the arc-shaped mounting plate as the mounting medium for the abutment balls. The two contact surfaces formed by the abutment balls can be positioned and supported by the inner wall of the stator and the outer wall of the rotor, thereby avoiding the possibility of deformation of the rotating shaft on the rotor due to the large bending moment during the assembly process, and slidingly guide the rotor during the assembly process so that the rotating shaft on the rotor can smoothly pass through the bearing hole on the stator, thereby improving the assembly efficiency of the motor stator and rotor, and the relative position of the arc-shaped mounting plate and the placement seat can be changed by cooperating with the adjusting unit through the fixing ring, thereby facilitating the fixation of the stator.
