Description

Technical Field

[0001] This utility model belongs to the field of generator painting technology, specifically relating to a painting device for generator production. Background Technology

[0002] A generator is a mechanical device that converts other forms of energy into electrical energy. In order to improve its corrosion and rust resistance during the production process, generators are usually painted, and the paint coating is used to protect the generator casing.

[0003] In the current process of painting generators, most generators use nozzles to directly spray paint onto the generator casing. Since some generators need to ensure their heat dissipation performance, these generator casings are equipped with axially distributed heat dissipation fins. Because the heat dissipation fins form a relatively narrow space, the paint cannot fully penetrate and thus cannot cover the generator casing, reducing the generator's anti-corrosion and anti-rust performance.

[0004] Therefore, a painting device for generator production is proposed. Summary of the Invention

[0005] This utility model provides a painting device for generator production, the purpose of which is to solve the problems mentioned above.

[0006] This utility model provides a painting device for generator production, including a base; a stepper motor disposed through the center of the inner side of the base; a support tray fixed to the output end of the stepper motor; three brackets axially disposed at equal intervals on the top of the support tray; an inner painting assembly and an outer painting assembly disposed on the base, the inner painting assembly being located on one side of the outer painting assembly; wherein, the inner painting assembly includes: an outer rotating sleeve rotatable on the top of the base; a transmission gear disposed on the outer side wall of the outer rotating sleeve; an outer straight paint spray hole and an outer oblique paint spray hole opened on the outer side wall of the transmission gear, the outer straight paint spray hole being located on one side of the outer oblique paint spray hole; a support plate disposed on the top of the base near the outer rotating sleeve; a paint inlet pipe penetrating the top of the support plate; an inner fixing pipe disposed at the bottom end of the paint inlet pipe; and an inner painting hole opened on the outer side wall of the inner fixing pipe.

[0007] Furthermore, the external painting assembly includes a paint spraying base located on the top of the base, the top of the paint spraying base is provided with a paint inlet pipe, and a nozzle is provided on one side of the outer wall of the paint spraying base.

[0008] Furthermore, a generator housing is inserted into the inner side of the three card slots, and heat dissipation fins are provided on the outer side wall of the generator housing.

[0009] Furthermore, the inner wall of the outer rotating sleeve is precisely fitted to the outer wall of the inner fixed tube;

[0010] By adopting the above technical solution, it is ensured that the outer rotating sleeve fits precisely into the inner fixed tube, thus preventing paint leakage.

[0011] Furthermore, a total of several transmission teeth are provided, and the several transmission teeth are axially and equally spaced on the outer side wall of the outer rotating sleeve;

[0012] By adopting the above technical solution, with a portion of the transmission gear embedded between two heat dissipation fins on the generator housing, paint can be sprayed into the narrow space between the two heat dissipation fins, facilitating thorough spraying of the outer wall surface of the generator housing.

[0013] Furthermore, both the outer rotating sleeve and the inner fixed tube have a sealing end at their bottom.

[0014] By adopting the above technical solution, paint leakage is avoided and unidirectional flow of paint is guaranteed.

[0015] The beneficial effects of this utility model are as follows:

[0016] This invention utilizes the axial rotation of the generator housing to drive the transmission teeth, causing the outer sleeve to rotate accordingly. This allows several transmission teeth on the outer sleeve to be embedded one by one between two heat dissipation fins. Paint is then sprayed into the space between the two heat dissipation fins using external straight and external oblique paint spray holes, achieving narrow-space painting. This not only coats the surface of the heat dissipation fins but also the outer surface of the generator housing, achieving uniform and thorough painting and thus ensuring the generator's corrosion and rust prevention performance.

The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] Reference Figures 1-6 This utility model embodiment proposes a spray painting device for generator production, including a base 1, a stepper motor 2 is installed through the center of the top of the base 1, a support tray 3 is fixedly connected to the stepper motor 2 through the output end on one side, three card holders 4 are axially and equally spaced on the top of the support tray 3, a generator housing 7 is engaged on the top of the three card holders 4, and a number of heat dissipation fins 8 are axially and equally spaced on the outer side wall of the generator housing 7.

[0028] The outer sleeve 51 of the inner spray painting assembly 5 is rotatably connected to the top of the base 1 near the generator housing 7. Several transmission teeth 52 are provided on the outer wall of the outer sleeve 51, axially spaced at equal intervals. A portion of the transmission teeth 52 is embedded between two heat dissipation fins 8 on the generator housing 7, allowing paint to be sprayed into the narrow space between the two fins, facilitating thorough painting of the outer wall of the generator housing 7. An external direct spray nozzle 53 is provided on the outer wall of the transmission teeth 52 on the side away from the outer sleeve 51. An external oblique spray hole 54 is provided on the outer side wall of the tooth 52 near the side of the external straight spray hole 53. A support plate 55 is provided on the top of the base 1 near the side of the outer rotating sleeve 51. A paint inlet pipe 56 is provided through the top of the support plate 55. An inner fixing pipe 57 is provided at the bottom end of the paint inlet pipe 56. The inner side wall of the outer rotating sleeve 51 is precisely fitted to the outer side wall of the inner fixing pipe 57 to ensure that the outer rotating sleeve 51 is precisely fitted to the inner fixing pipe 57 and to prevent paint leakage. An internal spray hole 58 is provided on the outer side wall of the inner fixing pipe 57. Both the bottom ends of the outer rotating sleeve 51 and the inner fixing pipe 57 are sealed to prevent paint leakage and ensure unidirectional flow of paint.

[0029] A paint spraying station 61 of the external painting assembly 6 is provided on the top of the base 1 near the other side of the generator housing 7. A paint inlet pipe 62 is provided on the top of the paint spraying station 61, and a nozzle 63 is provided on one side of the outer wall of the paint spraying station 61 near the generator housing 7.

[0030] The specific implementation method is as follows: When painting the generator housing 7, the generator housing 7 is embedded in the three card slots 4. After the generator housing 7 is fixed, the paint is pumped into the paint inlet pipe 56 and the paint inlet pipe 62 by an external spraying pump. When the paint enters the spraying base 61, the paint is sprayed out onto the generator housing 7 through the nozzle 63. At this time, the stepper motor 2 is controlled to drive the support tray 3 to rotate through its output end on one side. The support tray 3 and the generator housing 7 rotate synchronously. After the paint comes into contact with the outer wall of the generator housing 7 and the heat sink fins 8, it covers them and the painting is completed.

[0031] When the generator housing 7 rotates axially, the heat dissipation fins 8 press against the transmission teeth 52. Due to the rotational connection between the outer sleeve 51 and the base 1, the transmission teeth 52 are pushed by the heat dissipation fins 8, and several transmission teeth 52 on the outer sleeve 51 are embedded between the two heat dissipation fins 8 one by one. At this time, the paint enters the transmission teeth 52 through the inner spraying hole 58 on the inner fixed tube 57, and is sprayed from the outer straight spraying hole 53 and the outer oblique spraying hole 54 into the space between the two heat dissipation fins 8. This not only coats the surface of the heat dissipation fins 8, but also coats the outer surface of the generator housing 7, achieving uniform and sufficient painting. The generator housing 7 and the outer sleeve 51, which rotate together, can ensure the efficiency of the painting.
