Description

Technical Field

[0001] This utility model relates to the field of motor assembly technology, specifically to a stator and rotor assembly mechanism. Background Technology

[0002] In traditional motor manufacturing processes, the assembly of the stator and rotor is typically achieved manually or with simple mechanical tooling. In existing technologies, the stator and rotor are fixed separately using individual fixtures, and then their positions are manually adjusted during assembly. However, due to the magnetic force between the stator and rotor, the rotor is prone to shifting or deviating from its ideal position during actual operation, leading to a decrease in assembly accuracy. Furthermore, the diverse specifications of stators and rotors limit the compatibility of traditional fixtures, often requiring tooling replacement or adjustment, resulting in complex and inefficient operations.

[0003] On some highly automated production lines, although assembly equipment achieves automatic alignment and assembly of stators and rotors, it mostly employs rigid clamping and positioning methods, which are difficult to adapt to stators of different diameters and thicknesses, limiting the equipment's versatility. Furthermore, existing equipment often lacks effective sliding guidance and flexible adjustment mechanisms when clamping rotors, resulting in low clamping efficiency and potential damage to the rotor surface, affecting product quality. Therefore, this paper researches and improves upon these existing problems, providing a stator-rotor assembly mechanism to address current issues and enhance practical value. Utility Model Content

[0004] This utility model relates to a stator and rotor assembly mechanism, belonging to the field of motor assembly technology, and is particularly suitable for the precise assembly of stator and rotor. This utility model aims to solve the problems of insufficient assembly precision, poor adaptability, low clamping efficiency, and limited automation in existing technologies. By optimizing tooling design, it achieves efficient and precise assembly of stator and rotor.

[0005] This utility model includes a tooling base, a stator tooling assembly, and a rotor tooling assembly. Wherein:

[0006] 1. Tooling Design

[0007] The stator tooling assembly is used to clamp and position the stator; the rotor tooling assembly is used to clamp and position the rotor. Through the automatic lifting movement of the lifting seat, precise alignment and assembly are achieved between the stator and rotor tooling assemblies, avoiding the attraction of the stator's magnetic force on the rotor and ensuring assembly stability and efficiency.

[0008] 2. Stator tooling assembly

[0009] The stator tooling assembly includes a turntable base, a guide plate, and several clamping guide rods. The turntable base and the guide plate are respectively provided with a first guide groove and a second guide groove for guiding the clamping guide rods to slide and adjust on the surface of the turntable base. The surface of the clamping guide rods is provided with sliding pieces that elastically slide against the surface of the guide plate. Through the elastic pressing structure between the clamping head and the clamping guide rods, it can adapt to stators of different diameters and thicknesses, achieving flexible clamping and meeting the assembly requirements of multi-specification components.

[0010] 3. Rotor tooling assembly

[0011] The rotor tooling assembly includes a fixed sleeve, a movable sleeve, a drive rod, and several clamping blocks. The fixed sleeve is fixedly connected to the surface of the lifting seat and provides rotor clamping support. The movable sleeve is driven by the drive rod to deflect relative to the fixed sleeve. The clamping blocks achieve radial clamping and release through sliding guidance of radial guide grooves and guide grooves. The arc-shaped contact design between the clamping blocks and the guide grooves achieves efficient rotor clamping, resulting in a compact structure, improved assembly efficiency, and avoidance of damage to the rotor surface.

[0012] 4. Automated lifting and locking

[0013] The lifting platform achieves automatic lifting and adjustment via a lead screw motor and lead screw, and works in conjunction with the stator and rotor tooling assemblies to complete the precise assembly of the stator and rotor. The locking design of the locking lug plate further ensures stability during the assembly process and avoids alignment deviations.

[0014] 5. Multi-specification adaptability design

[0015] The first and second guide grooves are arc-shaped, and can be adapted to stators of different diameters by sliding the clamping guide rod. The clamping head slides up and down along the surface of the clamping guide rod through a threaded connection to a threaded nut, realizing the pressing and positioning of stators of different thicknesses. By sliding the clamping blocks in the diameter guide groove and guide groove, it can adapt to the clamping of rotors of different sizes, improving the versatility of the equipment.

[0016] Through the above structural design, this invention effectively avoids interference from the stator's magnetic force on the rotor, ensuring precise assembly of the stator and rotor. Simultaneously, the flexible clamping structure design adapts to various component specifications, improving the equipment's versatility and efficiency. This invention is suitable for stator and rotor assembly scenarios of various motors, offering advantages such as convenient operation, high assembly precision, and strong adaptability.

[0017] The beneficial effects achieved by this utility model are as follows:

[0018] 1. In this utility model, the tooling design of the stator and rotor is realized by stator tooling assembly and rotor tooling assembly respectively. Combined with the automatic lifting movement of the lifting seat, the stator magnetic force is avoided from attracting the rotor, while ensuring the precise assembly of the stator and rotor, thus improving the stability and efficiency of the assembly work.

[0019] 2. In this utility model, the sliding engagement of the clamping guide rod in the first and second guide grooves, and the elastic pressing design of the clamping head and the clamping guide rod, adapt to stators of different diameters and thicknesses, realizing the flexibility and reliability of stator clamping and meeting the processing requirements of multi-specification components; the rotor is clamped by driving the moving sleeve seat to deflect relative to the fixed sleeve seat through the driving rod, and by the sliding guidance of the clamping block in the radial guide groove and the guide groove. The structure is compact and efficient, improving the convenience of rotor clamping and release. Attached Figure Description
