Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0031] Example: Refer to Figure 1-Figure 3 A corrosion-resistant coating spraying device for precision gear production includes a chassis 1, and also includes: a mounting seat 3 fixedly mounted in the chassis 1, a rotating table 31 is rotatably arranged on the top of the mounting seat 3, and a plurality of processing tables 32 are arranged on the outer wall of the rotating table 31. In this embodiment, eight processing tables 32 are preferably arranged, and the eight processing tables 32 are circumferentially distributed on the side wall of the rotating table 31. Therefore, eight processing stations are arranged in the spraying device, namely, processing stations a, b, c, d, e, f, g, and h, wherein ab (the processing station 32 rotates from a to b, and so on) is a loading station; bc is a cleaning station; cd is a spraying station for the upper end face and the gear end face of the precision gear; de is a first gear exchange station; ef is a gear bottom spraying station; fg is a second gear exchange station; gh is a material taking station;

[0032] Reference Figure 1 and Figure 6 , multiple groups of processing tables 32 are provided with lifting components, and a first gear fixing platform 39 is fixedly installed on the top of the lifting component. The lifting component includes a coupling sleeve 33 rotatably connected to the processing table 32, and a multi-faceted shaft 34 is slidably connected to the coupling sleeve 33. The bottom of the multi-faceted shaft 34 is fixedly connected to a universal ball seat 35, and the top of the multi-faceted shaft 34 is fixedly connected to a connecting seat 38.

[0034] When the metal universal ball at the bottom of the universal ball seat 35 moves to the top of the second arc slope 22 , the second gear fixing platform 45 releases the precision gear, and the precision gear falls onto the first gear fixing platform 39 and follows the first gear fixing platform 39 to detach from the second gear fixing platform 45 .

[0035] During actual use, the precision gear is fixed on the first gear fixing platform 39 at the loading position ab, and then the rotating table 31 rotates. The rotating table 31 drives the precision gear to pass through the cleaning position bc for cleaning, and the first spraying component sprays corrosion-resistant paint on the upper end surface of the precision gear and the surface of the side wall teeth through the precision gear upper end surface and the gear tooth end surface spraying position cd. Then the precision gear passes through the precision gear upper end surface and the gear tooth end surface spraying position de to exchange the precision gear to move to the second gear fixing platform 45 to expose the lower end surface of the precision gear. When the precision gear passes through the gear bottom surface spraying position ef, the second spraying component sprays corrosion-resistant paint on the bottom surface of the precision gear. Then, the second gear fixing platform 45 is moved above the first gear fixing platform 39 through the second gear exchange position fg, and then the precision gear is removed through the material removal position gh.

[0037] High degree of automation: The device adopts multiple sets of processing tables 32 and lifting components, which can realize the automatic conversion and fixation of precision gears between different stations, reduce manual operations and improve production efficiency.

[0038] Good spraying consistency: The upper end face, side face and bottom face of the precision gear are sprayed by the first spraying assembly and the second spraying assembly to ensure the uniformity and consistency of the coating, avoiding the problem of uneven coating caused by manual operation.

[0039] Convenient exchange of precision gears: by moving the first arc slope 21 and the second arc slope 22 on the guide rail 2, rapid exchange of precision gears can be achieved, thereby improving production efficiency and operational convenience.

[0040] Excellent spraying effect: Through the spraying treatment of precision gears at different stations, the coating can be fully covered, which improves the quality and durability of the corrosion-resistant coating.

[0043] When in use, start the motor 313, the motor 313 drives the first transmission gear 314 to rotate, the first transmission gear 314 drives the first gear ring 312 to rotate, the first gear ring 312 drives the rotating table 31 to rotate, the rotating table 31 drives the multiple processing tables 32 to continue to rotate with the vertical axis of the rotating table 31 as the axis, during this process, the second transmission gear 36 cooperates with the second gear ring 37 to drive the polygonal shaft 34 to rotate, the polygonal shaft 34 is driven by the connecting seat 38 and the first gear fixing platform 39 to rotate, thereby driving the precision gear to rotate on the first gear fixing platform 39, when the precision gear rotates while passing through the cleaning position bc, the cleaning effect on the surface of the precision gear can be improved, when the precision gear rotates while passing through the upper end face of the precision gear and the gear tooth end face spraying position cd, the uniformity of spraying on the surface of the precision gear can be improved.

[0044] At the same time, the coupling sleeve 33 drives the transmission shaft 42 to rotate through the first synchronous pulley set 43, and the transmission shaft 42 drives the second gear fixing platform 45 to rotate through the second synchronous pulley set 44, so that the first gear fixing platform 39 and the second gear fixing platform 45 rotate synchronously with the same vertical axis as the axis, thereby improving the accuracy of precision gear exchange.

[0045] Reference Figure 8 A gear groove 46 is provided in the second gear fixing platform 45, and an electromagnet for attracting the tight gear is provided at the top of the gear groove 46, and a gap of 20-100 microns is reserved between the tooth groove wall of the gear groove 46 and the tooth surface of the unsprayed precision gear.

[0046] Among them, the gap of 20-100 microns can be set according to the thickness of the paint to be sprayed on the precision gear. The size of the precision gear after spraying the corrosion-resistant paint is set to mesh with the gear groove 46. Therefore, when the precision gear after the top and side surfaces are sprayed is inserted into the gear groove 46, the excess corrosion-resistant paint on the side of the gear can be scraped off through the notch of the gear groove 46 to prevent the excessively thick corrosion-resistant coating from affecting the accuracy of the precision gear.

[0048] Start the first feeding pump 6, which absorbs the corrosion-resistant paint in the storage barrel 12 through the first feeding pipe 61, and then discharges it into the first paint nozzle 64 through the first discharging pipe 63. The paint is sprayed to the top and side walls of the precision gear through the first paint nozzle 64, and cooperates with the rotating precision gear to comprehensively spray the top and side surfaces of the precision gear.

[0049] In addition, during the rotation of the rotating table 31, the rotating table 31 drives the mounting rod 14 to rotate through the mounting cover 13, and the mounting rod 14 drives the stirring rod 11 to stir the corrosion-resistant coating in the storage barrel 12 to prevent the corrosion-resistant coating from settling.

[0050] Reference Figure 3-Figure 7 The second spraying assembly includes a second feeding pump 7 fixedly connected to the outer wall of the movable guide rail 2, the input end of the second feeding pump 7 is fixedly connected to a second feeding pipe 71, the output end of the second feeding pump 7 is fixedly connected to a second discharge pipe 72, the output end of the second discharge pipe 72 is fixedly connected to a second paint nozzle 73, and the second paint nozzle 73 faces the bottom of the precision gear.

[0051] The second feeding pump 7 is started, and the second feeding pump 7 draws the corrosion-resistant feed in the storage barrel 12 through the second feeding pipe 71, and sprays it through the second discharge pipe 72 and the second coating nozzle 73 to spray the bottom surface of the precision gear.

[0053] When the precision gear is a center hole sealing gear, the precision gear is inserted into the gear groove 46. When the coating thickness of the precision gear after the top surface and the side surface are sprayed meets the requirements, the precision gear is sealed with the groove wall of the gear groove 46, thereby squeezing the air in the gear groove 46 into the first air pipe 5. The gas flow rate is detected by the gas flow detection sensor 53. When the gas flow rate is less than a preset threshold value, the alarm can be controlled by the wireless control module to sound an alarm, alerting the staff that the side spraying accuracy of the precision gear is not enough.

[0054] When the precision gear passes through the first arc slope 21, which is the spraying position de for the upper end face of the precision gear and the gear tooth end face, the precision gear located at the spraying position de for the upper end face of the precision gear and the gear tooth end face squeezes the air in the gear groove 46 at this position into the second air pipe 51 located at the cleaning position bc, so that the gas is ejected through the high-pressure nozzle 52 and blown to the surface of the precision gear to clean the surface of the precision gear, thereby improving the uniformity of the corrosion-resistant coating on the surface of the precision gear.
