Therefore, in the production process of YBS series motors with fan covers, the welding requirements for the appearance of various parts are very strict. Take the air-cooled motor products YBS-200, 250, 200A, and 200B as examples to design the universal tooling for the fan cover: the original process method is to weld the fan cover, which generally includes baffles, support plates, wind cover rings, and wind cover windows. During normal welding, two people are required to cooperate with the control center height, one person uses a steel ruler to measure the benchmark, and one person fixes the live parts for suspended spot welding. For the operator, benchmark measurement is troublesome, time-consuming, and labor-intensive. Summary of the invention

[0003] The utility model aims to provide a universal positioning device for a motor fan cover.

[0004] A universal positioning device for a motor fan cover comprises a positioning plate, a first supporting rib, a first positioning ring, a second supporting rib and a second positioning ring, wherein one end of the first supporting rib is fixedly connected to the positioning plate, and the other end is fixedly connected to the first positioning ring, one end of the second supporting rib is fixedly connected to the first positioning ring, and the other end is fixedly connected to the second positioning ring, and a groove is provided on the positioning plate.

[0005] Preferably, the number of the first support ribs and the number of the second support ribs are both not less than three.

[0006] The original process method: for the assembly welding of the fan cover, the fan cover assembly welding generally includes a baffle, a support plate, a hood ring, and a hood window. During normal assembly welding, two people are required to cooperate to control the center height, one person uses a steel ruler to measure the benchmark, and one person fixes the live parts for spot welding in the air. For the operator, the benchmark measurement is troublesome, time-consuming, and labor-consuming. With the utility model, the positioning plate is placed on the platform as the bottom surface, the baffle of the fan cover assembly is placed into the stop of the support plate, and the first supporting rib is spot welded according to the given angle of the universal positioning device of the motor fan cover according to the groove opened on the positioning plate, and the hood window and the hood ring are fixed according to the first circle and the second positioning circle as the benchmark to control the center height size. With this universal positioning device for the motor fan cover, only one person is needed to complete the riveting and welding accurately and quickly, saving time and manpower.
