Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings.

[0018] refer to figure 1 , figure 2 , a motor stator potting tool, including a lower base 1, an upper base 2 on the upper part of the lower base 1, a pressure plate 3, and a mandrel 4. The lower base 1 is provided with a lower base that matches the outer wall of the plastic end cup at the lower end of the stator assembly. Cavity 11, an upper cavity 21 matching the outer wall of the plastic end cup at the upper end of the stator assembly is provided at the axis of the upper base 2, and the inner wall of the lower cavity 11 is an inverted cone that matches the outer wall of the plastic end cup at the lower end of the stator assembly. The inner wall of the lower cavity 12 is tapered to coincide with the outer wall of the plastic end cup at the upper end of the stator assembly. The tapered structure facilitates the smooth detachment of the stator assembly after glue fill...

Abstract

The present invention relates to a motor stator technology field, in particular to a motor stator pouring and sealing method and a motor stator pouring and sealing tooling. The plastic end cups sleevethe two ends of an assembled stator assembly, the stator assembly at the end parts of which the plastic end cups sleeve is clamped to a glue pouring tooling in a vacuumizing device, and the epoxy pouring sealant is poured into an inner hole of the stator assembly. The vacuumizing device vacuumizes, under a vacuum state, a core rod of which the diameter matches the inner hole of the stator assembly is inserted in the inner hole of the stator assembly from top to bottom, and under the extrusion of the core rod, the epoxy pouring sealant in the inner hole immerses and flows from inside to outside and from bottom to top along the inner slits of the stator assembly until the epoxy pouring sealant is poured full in all slits of the stator assembly and the space between the stator assembly and the plastic end cups. The stator is poured full by the pouring sealant from bottom to top and from inside to outside, so that the situation that the glue fills reliably is guaranteed, and under a vacuum environment, the bad pouring and sealing brought by the bubbles can be reduced.

Description

technical field [0001] The invention relates to the technical field of motor stators, in particular to a motor stator potting method and tooling. Background technique [0002] The stator assembly of the servo motor needs to be potted with epoxy resin to improve the moisture resistance of the stator, improve the protection level, electrical strength, and mechanical strength of the stator, and improve the life of the stator. In the existing method, potting is performed from one end of the stator assembly, and the effect of the potting glue soaking into the gap of the stator assembly is poor, which easily causes poor sealing and affects the quality of potting. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a motor stator potting method and tooling for the above defects. The potting glue fills the stator from bottom to top and from inside to outside to ensure reliable filling of glue. , can reduce poor potting caus...
