Description

Technical Field

[0001] The utility model relates to the field of motor stator coil processing, in particular to a motor stator paint dipping and lifting device. Background Art

[0002] In the motor production process, stator varnishing is an essential step. The varnishing process can improve the insulation strength and moisture resistance of the winding and extend the service life of the stator. During the stator varnishing process, the stator cannot be directly placed in the varnishing tank for varnishing. The stator needs to be fixed on the tooling, and the varnishing lifting device lifts the tooling to lift the stator to the varnishing tank or heating furnace.

[0003] There are two types of lifting devices currently in use: special lifting devices for direct-drive models and special lifting devices for semi-direct-drive stator models. The switching process is troublesome, and there is a lack of a common device for direct-drive and semi-direct-drive stator painting lifting. The stator painting lifting devices currently used are direct-drive stator painting lifting devices for direct-drive stators and semi-direct-drive stators for semi-direct-drive stators. They need to be lifted with their own tooling. During the machine model change process, the lifting device and the sling must be replaced at the same time. The lifting times are high, the number of tooling is large, and the storage area is large, which is inconvenient in actual use.

[0004] Therefore, the problems existing in the existing motor stator paint dipping and lifting device are effectively solved, and the utility model provides a motor stator paint dipping and lifting device. Utility Model Content

[0005] The utility model aims to overcome the defects described in the background technology, thereby providing a motor stator paint dipping and lifting device.

[0006] To achieve the above purpose, the technical solution of the utility model is:

[0007] A motor stator paint dipping lifting device comprises a lifting device body, the lifting device body comprises four main lifting arms arranged crosswise, an upper lifting hole is provided vertically upward at the geometric center of the lifting device body, a main lifting ear is extended downward from the lower end face of each main lifting arm, four main lifting ears are arranged in an array evenly distributed according to the circumference of the geometric center of the lifting device body; an extension lifting arm is installed at the end of the main lifting arm through a connecting flange bolt, a secondary lifting ear is extended downward from the lower end face of each main lifting arm, four main lifting ears are arranged in an array evenly distributed according to the circumference of the geometric center of the lifting device body; the four main lifting ears or the four secondary lifting ears are connected to a lifting rope, and an upper lifting ring and a lower lifting ring are respectively provided at the upper and lower ends, the upper lifting ring is buckled with the four main lifting ears or the four secondary lifting ears, and the lower lifting ring is the load-bearing end; the lifting rope is subjected to a gluing treatment on the outer surface to facilitate the treatment of paint dipping.

[0008] Furthermore, the upper end surface of the sling body is provided with cross-shaped reinforcing ribs, and the main lifting hole is arranged at the center of the cross-shaped reinforcing ribs; such an arrangement can enhance the torsional strength of the cross-shaped main lifting arm.

[0009] Furthermore, a reinforcing patch is fixedly welded on the cross reinforcing ribs on the outer peripheral surface of the main lifting hole. When too heavy is placed, the lifting hole is deformed, causing the lifting device to tilt or even fall off.

[0010] Furthermore, boom reinforcement ribs are provided between each of the main booms to further prevent deformation of the four main booms.

[0011] Furthermore, the load-bearing end is a direct-drive stator coil or a stator coil tray carrying a semi-direct-drive stator coil.

[0012] When the utility model is in use, the balance of the stator coil during the paint dipping can be achieved through the cross-shaped main boom and the evenly distributed suspension ropes. By arranging the extended boom, the length of the boom is increased, so that stator coils of different sizes can be hoisted. When the direct-driven stator coil with a larger outer diameter is hoisted, the suspension rope is installed on the auxiliary suspension ear of the extended boom, and the lower suspension ring of the suspension rope is connected to the suspension plate on the direct-driven stator coil to directly hoist the direct-driven stator coil; when the semi-direct-driven stator coil with a small outer diameter is hoisted, the semi-direct-driven stator coil is evenly placed on the stator coil tray, and the semi-direct-driven stator coil is hoisted by the tray; after the stator coil is hoisted, it enters the paint dipping equipment for paint dipping.

[0013] The benefits of the present invention are:

[0014] By setting an extended boom, the length of the boom is increased, so that stator coils of different sizes can be hoisted, and the stator coils are hoisted to the heating equipment for drying through the stator paint dipping hoisting general device. After drying, they are hoisted into the paint dipping equipment for paint dipping. It is suitable for the hoisting of stator coils of different models, reduces the hoisting and switching of tooling, improves production efficiency, and saves tooling manufacturing costs.
