Detailed Description
As shown in fig. 2-4, the utility model comprises an encapsulating main body tool 2; a discharging tool 8 is arranged below the encapsulating main body tool 2; the discharging tool 8 is connected with the encapsulating main body tool 2; the main filling and sealing tool 2 is provided with a through filling metal pipe 1, the discharging tool 8 is provided with a through filling and sealing glue circulation channel 13, and the filling metal pipe 1 is communicated with the circulation channel 13; a plurality of discharging metal pipe fixing holes 12 are formed in the side wall of the discharging tool 8, the fixing holes 12 are communicated with the circulation channel 13, and the discharging tool 8 is connected with the discharging metal pipe 7 through the fixing holes 12.
As shown in fig. 1, the fixture is an integral structure of a conventional motor stator potting fixture for high-viscosity insulating glue; which is positioned in the motor shell 4 and in the middle of the motor stator core 5 (and the motor winding end 3). The utility model discloses to annotate material tubular metal resonator 1 and ejection of compact frock 8 as the purpose of split type structure does: the service life of the tool is prolonged. Meanwhile, the tool cannot be reused due to the blockage of materials during encapsulation, and once the blockage of the encapsulation materials is caused, the tool can be disassembled to remove the blocked part. Each component is of a simple straight cylinder design, and the purpose of the design is to facilitate cleaning of glue blocked by the component with a tool.
