Description

Technical Field

[0001] The utility model relates to the technical field of motor stator processing, in particular to a drying device for motor stator windings after varnish dipping. Background Art

[0002] The motor stator is an important component of motors such as generators and starters. The stator is an important part of the electric motor. The stator consists of three parts: the stator core, the stator winding and the frame. The main function of the stator is to generate a rotating magnetic field, and the main function of the rotor is to be cut by the magnetic lines of force in the rotating magnetic field to generate (output) current.

[0003] After the motor stator winding is dipped in paint, it is usually manually pushed into the drying chamber for drying. During the pushing process, it is easy to be burned by the high temperature of the drying chamber. Manual delivery is less safe, and after drying, it needs to be taken out, and then the motor stator winding is removed and a new batch is placed. The process is also time-consuming.

[0022] The support column 1 and the drying bin 12 are installed together on the base. When a set of cover plates 10 moves to the top of the drying bin 12, the cylinder 9 can be started to cover the cover plates 10 downward on the annular frame 701 to block the aperture of the annular frame 701. After drying, the placement rack 11 is lifted out of the drying bin 12, and the movable rack 7 can be driven by the motor 4 to rotate one hundred and eighty degrees, so that another set of cover plates 10 is moved to the top of the drying bin 12. After that, the motor stator winding after drying is removed, and the motor stator winding to be dried is placed and waits for drying.

[0023] A support frame 2 is also installed on the support column 1, and the support frame 2 supports the ring frame 3 through the pillar. The ring frame 3 is used to auxiliary support the bottom of the mobile frame 7, and the bottom of the mobile frame 7 can slide against the ring frame 3; an arc-shaped groove is provided on the bottom side of the middle part of the mobile frame 7 to match the ring frame 3, so that the mobile frame 7 can be supported by the ring frame 3 and slide in close proximity; the middle aperture of the ring frame 701 at both ends of the mobile frame 7 is matched with the opening diameter of the drying bin 12, and when the ring frame 701 moves to the top of the drying bin 12, it fits with the top of the drying bin 12; it can effectively reduce the outflow of hot air and better dry the stator winding of the motor.

[0024] The diameter of the cover plate 10 is set to be larger than the aperture of the annular frame 701; a protrusion is provided at the bottom of the cover plate 10, and the protrusion can be embedded in the annular frame 701 to effectively reduce the outflow of hot air.

[0026] Working principle: When in use, the motor stator winding can be placed on a group of placement racks 11, and then the driving ring rack 3 drives the gear shaft 6 to rotate through the gear 5, and the gear shaft 6 synchronously drives the mobile rack 7 to rotate, so that the group of placement racks 11 loaded with the motor stator winding are moved to the top of the drying bin 12. At this time, the ring rack 701 at the end of the mobile rack 7 is attached to the top surface of the drying bin 12, and then the cylinder 9 is driven to cover the cover plate 10 on the ring rack 701, and the motor stator winding on the placement rack 11 is sent into the drying bin 12, and the upper end of the drying bin 12 is covered and closed.
