Description

Technical Field

[0001] This application relates to the field of rotor assembly technology, and more specifically, to a rotor chip assembly fixture. Background Technology

[0002] In modern industry, electric motors, as key power devices, are used in every corner of the industry, from traditional manufacturing to emerging technology sectors. With the continuous improvement of industrial automation, the booming development of the electric vehicle industry, and the widespread adoption of smart home devices, the requirements for motor performance are becoming increasingly stringent. The performance of an electric motor largely depends on the quality of its rotor assembly, and the precise assembly of the rotor core is one of the key factors ensuring rotor performance.

[0003] The rotor core assembly fixture with publication number CN220382901U uses a storage cavity within a fixing ring to house the rotor. Simultaneously, an internal clamping assembly clamps and secures the rotor, ensuring the mounting end faces the top. The rotor core is aligned with the rotor, and a hydraulic cylinder is activated to press the rotor core into the rotor's inner cavity. During pressing, a buffer layer protects the rotor core. Furthermore, the installation depth of the rotor core can be controlled by adjusting the pressing depth of the hydraulic cylinder, thereby improving both the installation efficiency and quality of the rotor core.

[0004] While this patent improves the installation efficiency of the rotor core, its single-station design presents significant limitations. Specifically, in its assembly process, once the core is pressed into the rotor cavity, the assembly is complete. To begin assembling the next rotor, the new rotor must first be repositioned and secured in the storage chamber before the new rotor core is pressed into the rotor cavity. This single-station working mode results in a noticeable intermittent production process. The unavoidable pauses between each assembly operation, like a discontinuous chain, disrupt the continuity of production. Utility Model Content

[0032] The second motor 20 serves as a power source, and the output end thereof is fixedly connected with the turntable 2 through a shaft body. When the second motor 20 is started, the rotation of the turntable 2 is transmitted to the turntable 2 through the shaft body, so that the turntable 2 rotates around the shaft center on the top of the workbench 1. A plurality of placement rings 9 are arranged on the turntable 2, and the placement rings 9 rotate together with the turntable 2.

[0033] Each time the turntable 2 rotates by 72 degrees, the placement ring 9 located at the bottom of the extrusion disc 8 or the grabbing clamp 16 is driven to rotate.

[0034] When it is necessary to clamp the rotor shell, the rotor shell is placed into the placement ring 9 through the grabbing clamp 16, the electric push rod 18 is retracted, the arc-shaped plate 19 is driven to move towards the center of the placement ring 9, and the arc-shaped plate 19 is in close contact with the rotor shell and clamps the rotor shell. This clamping mode can adapt to rotor shells of different sizes, and the distance between the arc-shaped plates 19 can be changed by adjusting the stroke of the electric push rod 18, so that rotor shells of different outer diameters can be stably clamped.

[0035] The plurality of placement rings 9 arranged on the turntable 2 realize the function of multiple stations, so that the assembly process can be continuously carried out. When one placement ring 9 is performing a certain process (such as pressing the iron core and the rotor shell), other placement rings 9 can simultaneously perform feeding, discharging or other preparation work. This parallel operation mode greatly shortens the total time of each rotor core assembly, compared with the single-station assembly tool, more products can be produced in unit time, the production efficiency is improved, and it is especially suitable for large-scale production scenes.

The rotating angle is also not more than 180 degrees. After clamping is completed, it is rotated back to make the grab 16 located inside the placement ring 9. At this time, the core material is placed inside the rotor shell. At this time, although the core is located inside the material, due to the existence of the processing tolerance, there may be a small gap between the core and the shell. The extrusion disc 8 is used for extrusion, so that the core and the shell are tightly attached, the potential gap is eliminated, and the close fit between the two is ensured.

When feeding, the first motor 11 located at the bottom of the L-shaped plate 10 drives the rotating shaft 12 to rotate (the angle is not more than 180 degrees), so that the connecting block 13 and the fixed plate 14 connected with the rotating shaft 12 rotate, drive the grab 16 located between the two limiting rails 15 and slidingly connected with the limiting rails 15 at both ends to move to the rotor shell material, the cylinder 17 drives the grab 16 to descend and clamp the rotor shell, the two electric push rods 18 in the placing ring 9 contract, drive the arc-shaped plates 19 at the opposite ends to move to the center, clamp the rotor shell, then the grab 16 rises, the first motor 11 drives the rotating shaft 12 to rotate to the iron core material to clamp the iron core, then rotates back to make the grab 16 be located above the placing ring 9, put the iron core into the rotor shell in the placing ring 9, then the second motor 20 drives the rotating disc 2 to rotate, so that the rotor shell and the iron core in the placing ring 9 rotate to the lower side of the extrusion disc 8, the hydraulic cylinder 6 extends and contracts to drive the extrusion disc 8 to move downward, extrude the rotor shell and the iron core in the placing ring 9, make the iron core and the shell closely fit, eliminate the gap due to the machining tolerance, realize the close fit, complete a series of work of the rotor core assembly tool through such a process.
