Description

Technical Field

[0001] This utility model relates to the field of stator production equipment technology, and in particular to a tooling for applying adhesive to motor stators. Background Technology

[0002] The stator potting process is a key step in improving the insulation, heat dissipation, and structural strength of motors. Traditional glue-filling fixtures often employ a single-point glue inlet and vertical venting design. For example, patent CN222107754U discloses a glue-filling fixture for a motor stator, which includes an upper mold, a lower mold, and a mold core assembly. The mold core assembly is installed inside the stator core and includes a mold core inner liner, a mold core body, and a mold core outer liner arranged coaxially from the inside to the outside. A glue inlet channel is opened in the center of the mold core inner liner, and a mold core gasket is fixed at the bottom of the mold core body. The mold core gasket has several branch channels that communicate with the glue inlet channel at intervals along its circumference. This utility model utilizes interconnected glue inlet channels and branch channels for bottom-up glue filling, resulting in a high glue filling rate and good potting effect. Furthermore, the mold core assembly adopts a split structure, so when damaged, only the corresponding parts need to be replaced, reducing maintenance costs. Moreover, different materials are used for each part, which can control the radial expansion of the mold core assembly. While ensuring the sealing between the side wall of the mold core assembly and the inner wall of the stator core, it reduces the compressive stress, facilitates the recovery of dimensions after cooling, and extends the service life.

[0003] The above technical solution improves the filling rate through a split mold core assembly. However, its single glue inlet channel is prone to localized insufficient filling, affecting the overall performance of the stator and failing to meet actual production needs. Summary of the Invention

[0004] The purpose of this utility model is to solve the above-mentioned shortcomings in the existing technology by proposing a motor stator glue-applying tool.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Design a motor stator glue-applying fixture, including a stator core, a stator housing, a mold core inserted inside the stator core, a glue-inlet channel within the mold core, an upper mold fixed to the top of the stator housing, vent holes on the upper mold, and a lower mold fixed to the bottom of the stator housing, and also includes...

[0007] A support box is disposed at the bottom of the lower mold, the mold core extends toward the bottom of the support box to form a central column, and the glue injection channel extends toward the central column to form a central channel;

[0008] A spiral flow guide assembly is disposed within the lower mold and connected to the central channel via a central flow divider assembly. The central flow divider assembly includes a plurality of flow divider pipes arrayed along the outer wall of the central column and a guide portion connecting the flow divider pipes and the spiral flow guide assembly.

[0009] Furthermore, the spiral guide assembly includes multiple columns disposed between adjacent diversion pipes, at least three glue outlets arrayed on the top of the columns, and a spiral channel opened in the column and communicating with the glue outlets.

[0010] Furthermore, the outlet direction of the glue outlet forms an angle α with the horizontal plane of the top of the column, wherein 60° <a<80°。

[0011] Furthermore, the column and the lower mold are sealed together, with one end of the column located inside the box and the other end extending toward the stator core.

[0012] Furthermore, the center lines connecting the multiple dispensing ports on the same column form a regular polygon.

[0013] Furthermore, the guide section includes an arc-shaped pipe, an inlet pipe connecting the arc-shaped pipe and the diversion pipe, and an outlet pipe connecting the arc-shaped pipe and the spiral channel.

[0014] Furthermore, heating rods are spaced apart at the bottom of the diversion pipe.

[0015] The beneficial effects of the motor stator glue-applying fixture proposed in this utility model are as follows:

[0016] This invention forms a continuous glue supply channel by setting up a support box and a central column. Multi-directional flow is achieved through the flow distribution pipe of the central flow distribution component. The spiral flow guide component is spatially matched with the stator slot to form a glue filling path from the central channel to the flow distribution pipe, guide part and spiral channel. This solves the problem of uneven filling caused by the traditional single glue inlet channel and achieves uniform glue filling through multi-stage flow distribution. Attached Figure Description

[0027] By setting the support box body 6 and the central column 9 in the present utility model, a continuous glue supply channel is formed. Multi-directional diversion is achieved through the diversion pipes 801 of the central diversion component 8.
