Description

Technical Field

[0001] The invention discloses an auxiliary device for potting a sensor stator component, belonging to the technical field of potting a sensor stator component. Background Art

[0002] During the manufacturing process of the sensor stator assembly, the stator assembly is made of a coil, a shell, front and rear end covers, which are embedded, welded and potted. In order to ensure that the coil inside the shell is fixed and does not move or break when the sensor is in operation, the stator assembly is usually potted. When potting the assembly, it is necessary to use an auxiliary device to fix the potting and baking curing. Otherwise, the potting material will flow out along the lead-out hole of the lead-out wire, and the sleeve on the lead-out wire will harden as the potting material attached to it solidifies, causing the assembly to be unable to continue to be used, thereby wasting production costs and affecting the product production cycle. Therefore, an auxiliary device that can adjust the component to any angle of inclination is required for potting. Summary of the invention
