[0002] In the field of rotor manufacturing, traditional production methods generally rely on multiple independent machines and manual operation for shaft machining, press-fitting, and grinding processes, resulting in low automation, poor process coordination, and slow production cycle. Furthermore, the lack of online detection and precise positioning mechanisms makes it easy for positioning errors to occur when workpieces move between different workstations, affecting machining accuracy and product consistency, and failing to meet the requirements of modern intelligent manufacturing for high precision, high efficiency, and high-quality stability. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in the prior art by providing an automated rotor processing production line.

[0004] The objective of this invention can be achieved through the following technical solution: an automatic rotor processing production line, characterized in that it includes a control system, a moving truss, and two feeding mechanisms for automatic feeding, with a shaft processing station, a pressing station, and a grinding station arranged in order below the truss; The two feeding mechanisms are located at the front and rear ends of the shaft processing station, respectively, and are used for feeding the shaft raw material and the rotor component; At both ends of the mobile truss are respectively provided a loading robot and a unloading robot for loading and unloading, which can move laterally. The mobile truss is also provided with a number of movable clamping robots for clamping workpieces. The automatic machining production line for rotors also includes multiple rotating mechanisms that can drive the workpiece to rotate axially, a center hole detection mechanism for detecting the center hole at the shaft end, and an outer circle detection mechanism for detecting the outer circle of the shaft. The feeding mechanism, shaft processing station, pressing station, grinding station, loading robot, unloading robot, and clamping robot work together under the control of the control system to complete the automated production steps of the rotor.

A locking plate is hinged inside the positioning component, and the locking plate can be controlled by a cylinder to rotate and limit and lock the bearing component and the guide component inside the positioning component.

[0006] In the aforementioned rotor automatic machining production line, the rotating mechanism includes a transfer and feeding assembly and a rotating assembly that can drive the workpiece to rotate. The rotating assembly consists of a rotatable chuck for clamping the workpiece and a drive unit that drives the chuck to rotate and clamp. The rotating mechanism is located at the front end of the shaft machining station and the grinding station, respectively, and is used for workpiece rotation and direction.

[0007] In the aforementioned rotor automatic machining production line, the shaft machining station is sequentially equipped with a CNC machine tool for double-sided shaft end machining and center hole drilling, two CNC lathes for shaft outer diameter machining, and a drilling and tapping machine for shaft end keyway flat machining. The center hole detection mechanism is located on the side of the CNC machine tool and is used for detection and positioning after center hole machining.

Between the pressing station and the shaft processing station, there is also a gripping mechanism for moving the workpiece and loading it into the pressing machine. The gripping mechanism, the pressing machine, and the pressing robot work together to complete the automatic rotor pressing steps under the control of the control system.

[0010] In the aforementioned automatic rotor processing production line, a high-speed grinding machine, a conventional grinding machine, and a precision grinding machine are sequentially installed in the grinding station, which are used for rough and fine grinding of the workpiece after press fitting, respectively.

[0022] The rotating mechanism 9 includes a transfer and feeding assembly 21 and a rotating component that can drive the workpiece to rotate. The rotating component consists of a rotatable chuck 19 for clamping the workpiece and a drive unit 20 for driving the chuck 19 to rotate and clamp. The rotating mechanism 9 is located at the front end of the shaft machining station 3 and the grinding station 5, respectively, and is used for workpiece rotation and direction.

[0023] The shaft machining station 3 is arranged in sequence with one CNC machine tool for double-sided shaft end machining and center hole drilling, two CNC lathes for shaft outer diameter machining, and one drilling and tapping machine for shaft end keyway flat machining. The center hole inspection mechanism 10 is located on the side of the CNC machine tool and is used for inspection and positioning after center hole machining.

[0025] The pressing station 4 is equipped with a pressing machine and a movable pressing robot for loading and unloading materials. Between the pressing station 4 and the shaft processing station 3, there is also a gripping mechanism for moving the workpiece and loading it into the pressing machine. Under the control of the control system, the gripping mechanism, the pressing machine and the pressing robot work together to complete the automatic pressing steps of the rotor.

[0026] Grinding station 5 is equipped with a high-speed grinder, a conventional grinder, and a precision grinder, which are used for rough and fine grinding of the workpieces after press-fitting, respectively. A trolley is located below the unloading robot 7 for easy placement of finished products.

[0027] This invention integrates highly automated, modular layout, and intelligent control. Through the collaborative operation of a moving gantry 1 and multiple robotic arms, it achieves a closed-loop production process from material loading, processing, inspection, pressing, grinding, and unloading. Its core technological advantages lie in the precision and flexibility of workpiece movement between stations ensured by a precise feeding and positioning mechanism, online inspection units (such as center hole and outer circle detection), and a rotatable steering mechanism. This significantly improves production efficiency and product consistency while reducing labor costs and intervention intensity, achieving high-precision, high-stability, and intelligent production of rotor products.

[0028] This automated rotor processing production line uses a mobile gantry 1 as the core logistics carrier, in conjunction with multiple robotic arms, inspection mechanisms, and processing equipment, to achieve automated loading, processing, inspection, steering, pressing, grinding, and unloading of rotor workpieces. All actions are uniformly coordinated by the control system to ensure continuous processes, high precision, and excellent efficiency.

[0029] Production steps 1. Feeding stage: Two feeding mechanisms 2 provide shaft raw materials and rotor parts respectively. The feeding robot 6 grabs the shaft raw materials from the feeding mechanism 2 and places them into the shaft processing station 3.

[0030] 2. Shaft machining stage: The shaft is successively processed by CNC machine tools for double-sided shaft end machining and center hole drilling; CNC lathe is used for shaft outer diameter machining; drilling and tapping machine is used for shaft end keyway / flat square machining; center hole detection mechanism 10 and outer diameter detection mechanism 11 perform real-time detection during the machining process to ensure quality.

[0031] 3. Turning and Turning: The rotating mechanism 9 rotates and turns the workpiece at the front end of the key station to facilitate the next process of processing or inspection.

[0032] 4. Press-fitting stage: The processed shaft is transferred to press-fitting station 4 via a gripping mechanism. The press-fitting robot presses the rotor component onto the shaft to form the rotor assembly.

[0033] 5. Grinding stage: After pressing, the rotor is successively subjected to rough grinding on a high-speed grinding machine; medium grinding on a conventional grinding machine; and fine grinding on a precision grinding machine.

[0034] 6. Unloading stage: The unloading robot 7 takes the finished product out of the grinding station 5 and places it on the unloading trolley, completing the entire processing flow.
