This invention relates to the field of motor component manufacturing technology, specifically disclosing an auxiliary installation structure for a slotted commutator, including a frame and a fixing frame. The fixing frame is bolted to the center of the top of the frame, and a conveyor frame is located inside the frame. A servo electric cylinder drives the slider to linearly displace, and an eccentric wheel enables multiple adjusting plates to automatically align according to the angle of the commutator's top conical surface, forcibly aligning the commutator's central axis to coincide with the equipment's main shaft. This achieves a higher precision automatic alignment effect than traditional outer circle positioning. Furthermore, the limiting block automatically fine-tunes its position based on the actual outer diameter of the workpiece when contacting the commutator's outer circumference, ensuring uniform distribution of multi-point contact force. This avoids crushing of the insulating substrate or deformation of the copper sheet caused by rigid clamping, and effectively absorbs the impact of the reaction force generated during pressing, preventing slight slippage of the slotted commutator and thus ensuring the roundness and structural integrity of the finished commutator.

This utility model relates to an automatic commutator pressing device, including a worktable. The worktable is equipped with a commutator feeding mechanism, a first tilting mechanism, a conveying mechanism, a second tilting mechanism, and a pressing mechanism for pressing the rotor and commutator together. The first tilting mechanism includes a support frame, a tilting table, a rotary drive mechanism, and two positioning components for positioning the commutator. The tilting table is rotatably mounted on the support frame, and the rotary drive mechanism is mounted on the support frame. The drive end of the rotary drive mechanism is connected to the tilting table. The two positioning components are respectively mounted at the top and bottom of the tilting table. The rotary drive mechanism drives the tilting table to rotate the positioning components. This automatic commutator pressing device not only achieves automated pressing of the commutator and rotor but also improves pressing efficiency and accuracy, ensuring pressing quality.
