[0023] The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0024] As shown in the figure, a universal connection device for motor stator varnishing described in the present invention comprises a first dummy shaft 1, a connecting flange 2, a connecting tool 3, and a second dummy shaft 4. The connecting tool 3 is a hollow cylindrical structure with an opening at the top, and a connecting flange 2 (connected by bolts and removable) is movably provided on the top. The sides of the connecting tool 3 are columns 6 (support columns on both sides of the hollow window), and a hollow window is provided between adjacent columns 6. A connecting strip 7 is provided between the hollow windows, and a motor stator connecting hole 9 is provided on the connecting strip 7. A parallel head side connecting flange 10 is provided in the middle of the connecting flange 2, and the first dummy shaft 1 is fixed to the parallel head side connecting flange 10 through a first stop 13 and a first connecting hole 14. A non-parallel head side connecting flange 5 is provided in the middle of the bottom plate of the connecting tool 3, and the second dummy shaft 4 is fixed to the non-parallel head side connecting flange 5 through a second stop and a second connecting hole. The first dummy shaft 1, the connecting tool 3 and the second dummy shaft 4 are coaxially arranged.

[0025] The first dummy shaft 1 and the second dummy shaft 4 are used for turning over from a standing position to a lying position, and are also used for lying support.

[0026] A positioning block 8 is provided on the column 6; when the stator is placed in the connecting tool 3, it first plays a positioning role to facilitate fixed installation.

[0027] As an improvement of the present invention, a lifting hole is provided on the upper edge of the connecting tooling.

[0028] As an improvement of the present invention, rib plates are provided on the connecting flange and the connecting tooling bottom plate.

[0029] As an improvement of the present invention, a lifting hole is provided on the rib plate.

[0030] The universal connection device for motor stator varnish dipping described in the present invention has two methods of use:

[0031] (1) Horizontal varnishing: first, place the motor stator into the connecting fixture 3, use the positioning block 8 to position it, use bolts to connect and fix the motor stator from the motor connecting hole 9 (there are 2-4 groups of motor stator connecting holes, which firmly fix the stator), then install the connecting flange 2, place the connecting fixture 3 horizontally (axially placed horizontally), and finally install the first dummy shaft 1 and the second dummy shaft 4 on the connecting flange 2 and the bottom plate of the connecting fixture 3. A rib plate 11 is provided on the connecting flange 2 and the bottom plate of the connecting fixture 3, and a hoisting hole 12 is provided on the rib plate 11. The hoisting holes on both sides can be hung to achieve horizontal varnishing;

[0032] (2) Vertical varnishing: After removing the first dummy shaft 1, the second dummy shaft 2 and the connecting flange 3 (including the connecting flange 10 on the parallel side and the connecting flange 5 on the non-parallel side), since the upper edge of the connecting tooling 3 is also provided with a lifting hole, it can be lifted up to achieve vertical varnishing (the connecting tooling 3 is placed vertically in the axial direction).

[0033] The invention has a scientific structure and a simple and practical method, and solves the problem that vertical or horizontal paint dipping devices cannot be universally used. When the same product adopts vertical or horizontal paint dipping methods at the same time, the paint dipping connection device can be universalized, which can realize the universalization of devices, reduce device investment, and reduce production costs.

[0034] It should be noted that the above content only illustrates the technical idea of ​​the present invention and cannot be used to limit the protection scope of the present invention. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications all fall within the protection scope of the claims of the present invention.
