Technical Field

[0002] The surface treatment process of aluminum alloy wheels plays an important role in the automobile manufacturing industry. Aluminum alloy wheels have the advantages of light weight, high strength, corrosion resistance, and excellent heat dissipation performance. They have become an important component for vehicles to improve fuel efficiency and enhance handling stability. However, during the production process, aluminum alloy wheels will form some burrs, uneven surfaces, and local oxide layers after casting, which directly affect the appearance and long-term service life of the wheels.

[0048] How to use

[0049] Preparation: Place the aluminum alloy wheel on the conveying assembly of the loading unit 3 at the specified position, confirm that the equipment power supply and control cabinet 11 have been started, and check the sensor status to confirm that the equipment has entered the standby state.

[0050] Start operation: Press the start button, the control cabinet 11 will command the belt conveyor 13 of the feeding unit 3 to start, and the conveying assembly will convey the wheel to the positioning assembly; the lifting platform automatically adjusts the height to accommodate the wheel entering the grinding and polishing station.

[0051] Positioning and transportation: The electric cylinder 17 pushes the push plate 15 to accurately position the wheel; the loading robot 8 is started, and the picking component 9 grabs the wheel through the pneumatic shaft clamp and transports it to the grinding and polishing unit.

[0052] Surface treatment: The grinding wheel 6 in the grinding and polishing unit is started, and the grinding angle and pressure are automatically adjusted according to the wheel material and surface condition, and the wheel surface is accurately ground and polished. After grinding, the waste chips will fall into the receiving tray 7.

[0053] End of processing: After the grinding and polishing unit stops automatically, the robot moves the wheel from the grinding and polishing station back to the loading unit 3; the loading unit 3 starts again, sends out the processed wheel, and prepares for the loading of the next wheel.

[0054] Equipment shutdown: After all processing is completed, the operator can press the stop button and the equipment will enter standby mode.
