This invention discloses a laser welding device for the rim and spokes of thin-walled wheel hubs, relating to the field of wheel hub manufacturing technology. It includes a welding unit and a welding positioner. The welding unit comprises a welding robot and a oscillating laser welding head, the oscillating laser welding head being fixedly connected to the end effector of the welding robot's arm. The welding positioner includes a base, a tilting seat, a tilting drive device, a hollow turntable, and a rotation drive device. The tilting drive device drives the tilting seat to tilt, and the rotation drive device drives the hollow turntable to rotate. The hollow turntable has mounting holes for the rim and positioning fixtures for the spokes of the thin-walled wheel hub. This invention uses laser welding to replace traditional gas shielded welding, combining welding torch oscillation and workpiece displacement, effectively avoiding the burn-through problem when welding thin-walled wheel rims. It achieves high-quality, high-precision, and high-efficiency automated welding of the rim and spokes, meeting the urgent need for lightweight manufacturing of agricultural machinery wheel hubs.

The invention discloses a pipeline prefabrication machining platform which comprises a table top and a plurality of pipeline positioning devices arranged on the table top, each pipeline positioning device comprises a fixed-axis deformation frame and a rotating mechanism, and each fixed-axis deformation frame comprises a first ring body and a second ring body which are coaxially arranged; a plurality of connecting rods are evenly distributed between the first ring body and the second ring body in the circumferential direction, the connecting rods are equal in length, the two ends of each connecting rod are connected with the first ring body and the second ring body through spherical hinges respectively, the first ring body is rotationally supported on the annular sliding rail, and the second ring body is rotationally supported on the annular sliding rail. The second ring body is arranged on the linear sliding rail in a sliding manner; and the rotating mechanism controls the first ring body to rotate relative to the second ring body. The pipeline positioning device based on the fixed-axis deformation frame is arranged on the pipeline prefabrication machining platform, and fixed-axis self-adaptive positioning of the pipeline in the clamping process is achieved through the first ring body and the second ring body which are coaxially arranged and the equal-length connecting rods evenly distributed in the circumferential direction.

The application discloses a device pairing method, system, electrical equipment, medium and product, the method is applied to an electronic device, and is used for pairing a wireless control device with a target device, the wireless control device is provided with an NFC tag, and the method comprises the following steps: obtaining a target image of the target device, uploading the target image to a cloud, and receiving first device information fed back by the cloud, wherein the first device information is obtained by identifying the target image by the cloud; obtaining second device information of the target device, and determining target pairing parameters between the target device and the wireless control device based on the first device information and the second device information; and writing at least the target pairing parameters into the NFC tag of the wireless control device, so that the wireless control device completes pairing with the target device based on the written data in the NFC tag. The above scheme can realize accurate pairing between the wireless control device and the target device, the interaction is more intuitive, and the user experience is improved.
