DETAILED DESCRIPTION

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Please refer to Figures 1 and 2. Figure 1 is a structural schematic diagram of a rotor end cover assembly assembly positioning device provided in an embodiment of the present invention; Figure 2 is a structural schematic diagram of a stopping mechanism of a rotor end cover assembly assembly positioning device provided in an embodiment of the present invention.

[0030] The embodiment of the present invention provides a rotor end cover assembly assembly positioning device, comprising: a fixed platform 1, a manipulator 2 and a stopping mechanism 3, wherein the manipulator 2 is provided with an end cover setting pin 21, and the stopping mechanism 3 comprises a stopping pin 31 and a lifting assembly 32, wherein the lifting assembly 32 can be optionally a lifting cylinder. During positioning, the rotor end cover assembly 4 can be rotatably placed on the fixed platform 1, and the manipulator 2 can rotate the rotor end cover assembly 4 through the end cover setting pin 21 to adjust the angular position of the rotor end cover assembly 4, and then the lifting assembly 32 drives the stopping pin 31 to be inserted into the mounting hole of the rotor end cover assembly 4 to fix the angular position of the rotor end cover assembly 4, thereby limiting its rotation. Therefore, the assembly efficiency of the rotor end cover assembly 4 can be improved, and it is conducive to achieving the level of automated assembly of the rotor end cover assembly 4. After the stop pin 31 is inserted into the mounting hole of the rotor end cover assembly 4, the rotor end cover assembly 4 lifting tooling is installed to restrict the rotor end cover assembly 4 to a state where it cannot rotate freely. After the installation of the rotor end cover assembly 4 lifting tooling is completed, the robot end fixture grabs the rotor end cover assembly 4 lifting tooling to pick up the rotor end cover assembly 4. At the same time, the jacking component 32 drives the stop pin 31 to descend, and the workstation continues to complete the subsequent stator and rotor assembly operations. The position of the rotor end cover assembly 4 on the fixed table 1 can be adjusted by robot trajectory programming, and finally ensure that the distance from the center of the rotor end cover assembly 4 to the center of the stop pin 31 is equal to the pitch circle radius of the mounting hole.

[0031] In some embodiments, manipulator 2 is also equipped with a visual inspection system that can detect the position of rotor end cap assembly 4, particularly its characteristic points and locations, such as the positioning notch on the non-drive end outer bearing cap of rotor end cap assembly 4. The visual inspection system calculates the required rotation angle and feeds it back to manipulator 2. Manipulator 2 then inserts end cap shifting pin 21 into the mounting hole of rotor end cap assembly 4 and rotates the rotor end cap assembly 4 by the angle indicated by the visual inspection system. This visual inspection system can enhance the automation and flexibility of rotor end cap assembly 4 assembly.

[0032] In some embodiments, as shown in FIG2 , the stop mechanism 3 includes a plurality of stop pins 31 , and the spacing between the plurality of stop pins 31 and the fixed platform 1 is different. This is to adapt to rotor end cover assemblies 4 of different specifications and sizes, thereby improving the versatility of the rotor end cover assembly assembly positioning device. The stop pin 31 includes a pin rod 311 and an insertion end 312. The insertion end 312 is detachably connected to the upper end of the pin rod 311. When the insertion end 312 is worn, it can be replaced without replacing the entire stop pin 31, thereby reducing its maintenance cost. In order to facilitate the insertion of the end cover setting needle 21 and the stop pin 31 into the mounting hole, the end of the end cover setting needle 21 and the stop pin 31 facing the mounting hole are respectively provided with a tapered end. As shown in FIG1 and FIG2 , the lower end of the end cover setting needle 21 and the upper end of the stop pin 31 are provided with a tapered end, which can play a guiding role.

[0033] In some embodiments, as shown in Figure 2, the stationary platform 1 includes a bracket 11 and a support platform 12. The support platform 12 is positioned above the bracket 11 and has a through-hole for clearing the shaft assembly at the lower end of the rotor end cap assembly 4. The diameter of the through-hole is larger than that of the shaft assembly, which includes the shaft and accessories such as an oil seal installed on the shaft. The stop mechanism 3 is fixed to the side of the bracket 11. To adjust the stability and height of the bracket 11, multiple height-adjustable legs 13 can be provided at the bottom of the bracket 11.

[0034] In some embodiments, as shown in FIG2 , the stop mechanism 3 further includes a base 33, which is connected to the bracket 11. The base 33 is provided with a slide rail 34 and a slide plate 35. A lifting assembly 32 is provided on the base 33. The slide plate 35 is connected to the slide rail 34 for sliding up and down. The stop pin 31 is connected to the slide plate 35. The lifting assembly 32 is connected to the slide plate 35. The interaction between the slide plate 35 and the slide rail 34 can improve the stability and accuracy of the lifting of the stop pin 31. The slide plate 35 is provided with a fixed seat, and the stop pin 31 is detachably connected to the fixed seat. The detachable connection between the stop pin 31 and the fixed seat can facilitate the maintenance of the stop pin 31.
