Description

Technical Field

[0001] The utility model relates to the technical field of remanufacturing generators, in particular to a synchronous painting device for the inner and outer diameters of a generator stator. Background Art

[0002] In the process of processing the remanufactured generator stator, in order to improve the quality and performance of the generator stator and slow down the oxidation rate of the generator stator, it is necessary to spray paint the generator stator. Spraying anti-rust paint on the inner and outer diameter surfaces of the generator stator is the most popular anti-rust treatment method in the remanufactured generator industry, so there are many production jigs and automated equipment for spraying anti-rust paint on the generator stator. However, when the existing generator stator is painted, it is usually adopted to spray the outer diameter surface first and then spray the inner diameter surface after drying, or spray the inner diameter surface first and then spray the outer diameter surface after drying. In this way, the generator stator will be sprayed and dried twice, which will likely cause the paint layer to be scraped off during the movement. It is also possible that the paint layer on the inner and outer diameters of the generator stator will be unevenly sprayed during repeated spraying and drying, which will affect the efficiency of the subsequent reprocessing of the generator stator and produce defective products.

[0003] Announcement No. CN210729912U discloses a paint spraying device for motor stator processing, including a paint bucket, a motor, a rotating spindle, a hydraulic cylinder, a carrier, an auxiliary roller, a top plate, an infusion pump, a spray pipe and a discharge plate, characterized in that a groove is provided on the side wall of the paint bucket, the motor is arranged on the outer wall of the paint bucket, the rotating spindle is arranged in the paint bucket, the hydraulic cylinder is on the outer wall of the paint bucket, the carrier is arranged on the piston rod, connecting shafts are provided at both ends of the auxiliary roller, the top plate is arranged on the column, the infusion pump is arranged on the top plate, both ends of the spray pipe pass through the fixed plate, and one end of the discharge plate is arranged on the inner wall of the paint bucket. Although, this patent uses an infusion pump to transport the paint liquid through an infusion tube to a spray tube and sprays it out through a nozzle, and the sprayed paint liquid is sprayed onto the surface of the motor stator rotating with the rotating roller, thereby painting the motor stator, which improves work efficiency and can also improve the painting quality of the motor stator. However, the inner and outer diameters of the generator stator are not painted at the same time, which may cause the paint layer to be scraped off during movement, and may also cause uneven spraying of the paint layer on the inner and outer diameters of the generator stator during repeated spraying and drying, affecting the efficiency of subsequent reprocessing of the generator stator and producing defective products.

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0026] like Figure 1 and Figure 2 As shown, the utility model discloses a synchronous spraying device for inner and outer diameters of a generator stator, comprising: an outer diameter spraying device 1, an inner diameter spraying device 2, a tooling table 3, a rotating assembly, an exhaust gas filter mesh 4, a vent 5 and a paint mixer.

[0027] The outer diameter spraying device 1 includes an outer diameter spray gun 6, which is arranged on one side of the workbench 3. The inner diameter spraying device 2 includes an inner diameter spray gun 12, which is arranged on the top of the workbench 3, and the nozzle of the inner diameter spray gun 12 is facing the center of the workbench 3. The workbench 3 is used to install the generator stator, and the workbench 3 is connected to the rotating component and rotates under the control of the rotating component. The exhaust gas filter mesh 4 and the vent 5 are arranged at the back of the spraying operation position, and the exhaust gas filter mesh 4 is arranged in front of the vent 5.

[0028] In this embodiment, the outer diameter spray gun 6 is arranged on the left side of the workbench 3, and the exhaust gas filter mesh 4 adopts a replaceable filter cotton layer. The exhaust gas filter mesh 4 is a consumable material. If it is found to be blocked or the suction effect is poor, it needs to be replaced with a new mesh in time, and the replacement frequency is usually once a week.

[0029] In addition, in this embodiment, the exhaust gas filter mesh 4 is tilted and arranged in front of the vent 5. In other embodiments, the exhaust gas filter mesh 4 includes a main body section and an arc-shaped extension section, the main body section is arranged in front of the vent 5, the arc-shaped extension section is connected to the main body section, and the arc-shaped extension section is at least partially located on the periphery of the tooling table 3, such as Figure 6 shown.

[0030] like Figure 1 and Figure 3 As shown, the outer diameter spraying device 1 also includes: a support frame 7, a vertical support rod 8 and an outer diameter spraying power device 9, the support frame 7 is connected to the vertical support rod 8, the outer diameter spray gun 6 is installed on the support frame 7, and the vertical support rod 8 is installed on the outer diameter spraying power device 9. In this embodiment, the outer diameter spraying power device 9 adopts a stepping motor with a feedback signal to realize fast forward movement and working forward spraying operations.

[0031] like Figure 4 As shown, the inner diameter spraying device 2 further includes: an inner diameter spraying power device 13, and the inner diameter spray gun 12 is mounted on the inner diameter spraying power device 13. In this embodiment, the inner diameter spraying power device 13 uses a servo motor to realize fast-forward movement and working-feed spraying operations.

[0032] like Figure 3 As shown, the rotating assembly includes: a rotating spindle 10 and a rotating motor 11 , and the tooling table 3 is connected to the rotating motor 11 via the rotating spindle 10 .

[0033] The paint mixer (not shown in the figure) includes a pressure barrel, a paint delivery pipeline and a stirring assembly. The pressure barrel is filled with paint and is located on one side of the workbench. The stirring assembly is used to stir the paint in the pressure barrel. The paint delivery pipeline is connected to the pressure barrel. The paint delivery pipeline transfers the paint in the pressure barrel to the inner diameter spray gun and / or the outer diameter spray gun, and then sprays the paint through the inner diameter spray gun 12 and the outer diameter spray gun 6 onto the generator stator.

The start switch is pressed, the workpiece rotates automatically, and the automatic painting begins. The paint is transported from the paint delivery pipeline to the inner diameter spray gun 12 and the outer diameter spray gun 6 for each operation. After the spraying operation is completed, the workbench 3 stops rotating and the automatic painting ends. When changing the type of generator stator, it is necessary to manually adjust the parameters according to the size of the generator stator, including the rotation speed of the rotating spindle 10, the position distance of the inner diameter spray gun 12, and the automatic lifting height of the outer diameter spray gun 6.
