Description

Technical Field

[0001] This utility model relates to a rotor production equipment, and more particularly to a rotor outer circle grinding machine. Background Technology

[0002] After the rotor core is formed, its outer surface needs to be inspected and ground to meet precision requirements.

After grinding, the dimensions are checked again with calipers to ensure that the ground rotor core meets the requirements. This method results in numerous process steps, a long overall grinding time, low efficiency, high labor intensity for operators, a large number of operators, and high grinding costs.

[0031] The present invention will now be further described with reference to the accompanying drawings.

[0032] like Figures 1 to 15 As shown, a rotor outer diameter grinding machine includes a first material transfer device 1, a first detection device 2, a first conveying device 3, a second material transfer device 4, a grinding device 5, a third material transfer device 6, a cleaning device 7, a discharge device 9, and a second detection device 8, all mounted on a frame. The first detection device 2, the first conveying device 3, the cleaning device 7, and the discharge device 9 are arranged sequentially. The first material transfer device 1 is located on one side of the first conveying device 3 and the first detection device 2, and at one end of the frame. It is used to move the rotor core sent from the conveyor line to the first detection device 2 first, and then to the first conveying device 3. The grinding device 5 is located on one side of the first conveying device 3 and is used to grind the rotor core according to the detection result of the first detection device 2. In order to improve efficiency, two grinding devices 5 are provided, located on both sides of the first conveying device 3 respectively. The second transfer device 4 is located above the first conveying device 3 and opposite to the grinding device 5. It is used to transfer the rotor core, which has been inspected by the first inspection device 2 and is located on the first conveyor line, to the grinding device 5 for grinding.

[0033] The switching between different workstations is achieved through the first material transfer device 1, the second material transfer device 4, and the third material transfer device 6. The connection between the first inspection device 2, the grinding device 5, and the cleaning device 7 is achieved through the first conveying device 3, which facilitates the flow of the rotor core. The first inspection device 2 inspects the rotor core before grinding so that the grinding device 5 can perform grinding based on the inspection results.
