The technical solution of this invention has many beneficial effects, as described below: A stator potting fixture for a wind turbine product includes a potting shaft and a first potting cap and a second potting cap with a semi-ring structure. The first potting cap has first protrusions on both sides, and the second potting cap has second protrusions on both sides. A positioning platform is provided near the bottom surface of the potting shaft, and the positioning platform is used to support the product stator assembly; The area formed by the mating of the first and second potting caps can accommodate the potting shaft and the product stator assembly, and has a connected injection hole. The injection hole is connected to an external sealing device to realize the potting of the product stator assembly. The first protrusion and the second protrusion have threaded holes at corresponding positions for fixing the first potting cap and the second potting cap after they are engaged.

[0005] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects: During installation, the stator assembly of the fan product is mounted on the potting shaft. The potting shaft and the stator assembly are fitted with a small clearance. The height of the positioning platform is set according to the product model to meet the coaxiality requirements of small fans. The first and second potting caps are assembled on the circumference of the stator assembly through the potting shaft base. The gap between the potting caps ensures the product potting size. After aligning the potting caps, they are tightened with screws and nuts. Finally, the potting adhesive is injected through the injection hole. The bottom-up potting design and the venting hole can prevent the problem of incomplete potting. At the same time, the first and second potting caps can be reused after disassembly.
