Description

Technical Field

[0001] This utility model relates to a processing device for a high concentricity external rotor motor for wind turbines, belonging to the technical field of motor production equipment. Background Technology

[0002] An external rotor motor is a type of fan equipment that uses an external rotor motor as its power core to directly drive a fan impeller. The fan impeller is directly mounted on the outer rotor housing of the motor. When the motor rotates, the housing (i.e., the rotor) rotates along with the impeller. Since the motor rotor (housing) directly drives the impeller, intermediate transmission mechanisms such as belts and couplings are eliminated, resulting in a very compact fan unit structure. Currently, fan impellers are generally fixed to the outer rotor surface evenly along the circumference by welding. However, it is difficult to precisely match the impeller with the outer rotor during welding, which affects product quality. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a high concentricity external rotor motor processing device for wind turbines, which can facilitate the precise welding of the impeller and the external rotor, improve concentricity, and solve the shortcomings of the prior art.

[0004] The technical solution of this utility model is: a high concentricity external rotor motor processing device for wind turbines, used for connecting the external rotor and impeller of a wind turbine, including a platform, on which a wind turbine external rotor positioning mechanism and an impeller positioning mechanism are provided. The wind turbine external rotor positioning mechanism includes a cylinder and a plurality of claws evenly distributed along the circumference of the cylinder and driven synchronously by a driving device. The upper end of the cylinder is open for placing the wind turbine external rotor. The plurality of claws are driven synchronously to fix the wind turbine external rotor placed in the cylinder. The impeller positioning mechanism includes a plurality of pressing devices and positioning devices evenly distributed along the outer circumference of the cylinder. The positioning devices contact the impeller in multiple aspects to place the impeller in a fixed position that contacts the outer surface of the wind turbine external rotor. The pressing devices press down and fix the impeller placed on the positioning devices.

[0005] The further pressing device includes a rotary cylinder.

[0006] The platform is further supported by a base, and the base is equipped with a second drive device for rotating the platform. The platform has several hollow areas, and the projection of the hollow areas coincides with the back of the connection between the impeller and the outer rotor of the fan.

[0007] Furthermore, a welding robot is provided on the machine base.

[0008] Furthermore, the base is connected to a baffle and a sliding door that surround the platform.

[0009] By implementing this utility model, when in use, the outer rotor of the fan is placed in the cylinder. The driving device drives several claws evenly distributed along the circumference of the cylinder to move towards the center line of the cylinder to fix the outer rotor of the fan. The impellers are placed on the corresponding positioning devices so that the impellers are evenly distributed along the outer rotor of the fan. The inner end of the impeller is connected to the outer surface of the outer rotor of the fan. The pressing device presses down and fixes the impeller. The welding device welds and fixes the connection between the impeller and the outer surface of the outer rotor of the fan, so as to achieve precise welding between the impeller and the outer rotor and improve concentricity.

[0012] Embodiments of this utility model: such as Figures 1 to 5As shown, a high concentricity external rotor motor processing device for wind turbines is used to connect the external rotor 1 of a wind turbine to the impeller 2. It includes a platform 3, on which are mounted a wind turbine external rotor positioning mechanism and an impeller positioning mechanism. The wind turbine external rotor positioning mechanism includes a cylinder 4 and several claws 5 evenly distributed around the circumference of the cylinder 4, which are driven synchronously by a drive device. The upper end of the cylinder 4 is open for placing the wind turbine external rotor 1. The claws 5 are driven by a drive device 6 to move synchronously inward and outward or rotate around the cylinder 4 as a center line. In this application, the drive device 6 is a cylinder. The claws 5 are connected to the cylinder 4 and to the telescopic rod of the cylinder. The telescopic movement of the cylinder drives the claws 5 to rotate synchronously, placing them inside the cylinder 4. The outer rotor 1 of the fan is coaxially fixed in the cylinder 4. The impeller positioning mechanism includes several pressing devices and positioning devices evenly distributed along the outer periphery of the cylinder 4. The positioning device includes several support members 7 that support the impeller 2 and several stop bars 8 that limit the left and right sides and the outer side of the impeller 2. The impeller 2 is contacted and limited, so that the impeller 2 is placed in a fixed position that contacts the outer surface of the outer rotor 1 of the fan. If the impellers 2 are evenly distributed along the outer rotor 1 of the fan, the pressing device presses down and fixes the impellers 2 placed on the positioning device. The connection between the impeller 2 and the outer surface of the outer rotor 1 of the fan is welded and fixed by the welding device, so as to achieve precise matching welding between the impeller 2 and the outer rotor 1 of the fan and improve the concentricity.

[0013] As a preferred option, the pressing device includes a rotary cylinder 9. When the rotary cylinder 9 is in the rising position, it is offset from the impeller 2 by a certain angle. When pressing down and fixing, it first rotates to above the impeller 2 and then presses down, which facilitates the placement and removal of the impeller 2 and the welded outer rotor 1 of the fan.

[0014] As a preferred embodiment, the platform 3 is mounted on a base 10 and is connected to the base 10. The base 10 is equipped with a motor that drives the platform 3 to rotate. The motor is the second drive device. The platform 3 has several hollow areas 11. The projection of the hollow areas 11 coincides with the back of the connection between the impeller 2 and the outer rotor 1 of the fan. The welding device first welds the connection between the impeller 2 and the outer rotor 1 of the fan on the front side. Then, the motor drives the platform 3 to rotate 180 degrees. The welding device then welds the connection between the impeller 2 and the outer rotor 1 of the fan on the back side through the hollow areas 11, which facilitates welding on both sides. Afterward, the motor drives the platform 3 to rotate 180 degrees again, the pressing device lifts up, the chuck 5 is released from the outer rotor 1 of the fan, and the welded outer rotor of the fan is removed.

[0015] As a preferred option, the base 10 is equipped with a welding robot 12. The welding robot 12 is a prior art technology. It is controlled by multi-axis linkage and the welding path is controlled by a programming system. It automatically completes the welding of the impeller 2 and the outer rotor 1 of the fan, which improves the problems of high labor intensity in traditional welding operation environment.

[0016] As a preferred option, such as Figures 6 to 7As shown, the base 10 is connected to a baffle 13 and a sliding door 14 that surround the platform 3. Specifically, baffles 13 are set on both sides of the base 10, and a sliding door 14 is set between the two baffles 13. The sliding door 14 can slide relative to one of the baffles 13 to open and close. During welding, the sliding door 14 is slid to the closed state, and it cooperates with the two baffles 13 and the base 10 to surround the platform 3 and block the sparks that fly during welding. After welding is completed, the sliding door 14 is slid open, and the operator can enter to take out and replace the outer rotor of the fan.
