Description

Technical Field

[0001] The utility model relates to the technical field of spraying hangers, in particular to an automatic spraying hanger for producing aviation accessories. Background Art

[0002] Plunger pumps have many applications in the aviation field, mainly due to their high efficiency, reliability and ability to provide stable pressure. Its application examples include fuel delivery, hydraulic systems and lubrication systems, and the plunger pump chuck is one of the important accessories on the plunger pump. The plunger pump chuck has a large circular hole in its center and multiple small holes are equidistantly opened around the circular hole. In response to the corrosion resistance requirements of the plunger pump chuck, the plunger pump chuck needs to be sprayed, and the inner wall of the large hole of some plunger pump chucks needs to have specific surface properties, such as a specific friction coefficient or hardness. The inner wall of the large hole needs to be sprayed separately to meet these performance requirements, while the small hole is sprayed together with the outer wall of the plunger pump chuck. In the process of hanging spraying, some hangers need to hook the chuck to the small hole and then fix it on the supporting structure, which has a lot of obstruction on the outer wall and small hole of the chuck, and needs to be sprayed later. Some hangers have a fixed hanging method for the chuck. When spraying in a spray room with a fixed angle of some spray guns, some small holes of the chuck cannot be fully sprayed during the movement, which is inconvenient to use. Utility Model Content

Detailed implementation manner

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1 to 7 , in the embodiment of the present invention, an automatic spraying hanger for aviation parts production includes a hanging mechanism 10. The hanging mechanism 10 includes a fixed hanging plate 11. A connecting plate 111 is fixedly connected to the bottom of the fixed hanging plate 11. A sleeve 12 is rotatably connected to the bottom of the connecting plate 111. A sprocket 13 is fixedly sleeved on the outer wall of the sleeve 12. A plurality of limit seats 14 are rotatably connected to the outer wall of the sleeve 12. Two fixed clamping rods 141 for fixing the chuck body 20 are slidably connected to one side of the limit seat 14. A drive module 15 for driving the plurality of limit seats 14 to rotate reciprocally is arranged inside the fixed hanging plate 11.

[0023] Specifically, by rotatably connecting a plurality of limit seats 14 to the outer wall of the sleeve 12, the fixed clamping rods 141 sliding on the limit seats 14 can quickly clamp the chuck body 20. When the sleeve 12 moves on the suspension chain, the sprocket 13 and the chain drive the sleeve 12 to drive the plurality of chuck bodies 20 to rotate around. And the reciprocating up and down of the rectangular rod 151 drives the plurality of limit seats 14 to rotate reciprocally, so that the chuck body 20 can rotate around the sleeve 12 while rotating around, and can expose the small holes on it at multiple angles as much as possible, which is convenient for spraying the inner walls of the small holes on the chuck body 20 and preventing the small holes from being blocked during spraying.

[0024] Embodiment 1

[0025] As Figure 1-6 shown, in this embodiment, a ferrule 1411 is fixedly sleeved on the outer wall of the fixed clamping rod 141. Two sliders 144 are slidably connected inside the limit seat 14. The sliders 144 are fixedly connected to the adjacent fixed clamping rods 141. A return spring 145 is fixedly connected between the sliders 144 and the limit seat 14.

[0026] In this embodiment, two ferrule sleeves 1411 are clamped to the inner wall of the chuck body 20 and stretched in opposite directions, so as to quickly fix and limit the chuck body 20. The chuck body 20 can rotate between the outer walls of the two ferrule sleeves 1411 but cannot be detached. By using the fixed clamping rod 141 to limit the slider 144, the sliding limit of the fixed clamping rod 141 is realized, and the ferrule sleeve 1411 is driven by the return spring 145 to closely abut against the inner wall of the chuck body 20 to prevent detachment.

[0027] As Figure 1-5 shown, a plurality of arc-shaped plates 142 are fixedly connected to the outer wall of the sleeve 12. A shaft rod 143 is rotatably connected inside the arc-shaped plate 142. One end of the shaft rod 143 is fixedly connected to the adjacent limit seat 14. The other end of the shaft rod 143 penetrates through the sleeve 12 and extends into its interior. A gear 147 is fixedly sleeved on the other end of the shaft rod 143. A protective plate 146 is fixedly sleeved on the outer wall of the fixed clamping rod 141.

[0028] During specific implementation, the arc-shaped plate 142 is used to rotationally limit the shaft rod 143, so as to realize the rotational limit of the limit seat 14. The whole limit seat 14 is not in a vertical state, but keeps an inclined state of 15 degrees of the driving module. The limit seat 14, the fixed clamping rod 141 and the chuck body 20 thereon are driven to rotate through the shaft rod 143, so that multiple small holes on the chuck body 20 can be exposed at multiple angles, which is convenient for spraying the inner walls of the small holes on the chuck body 20 and prevents being blocked. The protective plate 146 is used to block the sliding position of the fixed clamping rod 141 and always blocks it during the movement of the fixed clamping rod 141 to prevent the spraying material from entering the limit seat 14.

[0029] Embodiment Two

[0030] On the basis of Embodiment One, in order to borrow the rotation of the sleeve 12 as power during the movement of the fixed suspension plate 11 and provide power for the rotation of multiple limit seats 14.

[0031] As Figure 1-5 shown, in this embodiment, the driving module 15 includes a rectangular rod 151. Two limit plates 152 are fixedly connected to the inner wall of the sleeve 12. The rectangular rod 151 penetrates through the limit plates 152 and is slidably connected to them. A plurality of racks 156 are fixedly connected to the outer walls of the rectangular rod 151, and the multiple racks 156 are at different heights. The rack 156 is meshed with the adjacent gear 147. A reciprocating lead screw 153 is fixedly connected to the bottom of the connecting plate 111. A U-shaped plate 154 is fixedly connected to the top of the rectangular rod 151. The reciprocating lead screw 153 penetrates through the top end of the U-shaped plate 154 and is threadedly connected to it. A clamping plate 155 is fixedly connected to the bottom end of the reciprocating lead screw 153.

[0032] In specific implementation, during the movement of the fixed suspension plate 11 on the suspension chain, the driving of the sprocket 13 and the chain causes the sleeve 12 to rotate at a constant speed. The sleeve 12 drives the rectangular rod 151 to rotate through the limiting plate 152 on its inner wall, thereby driving the U-shaped plate 154 to rotate. Under the drive of the reciprocating lead screw 153, the U-shaped plate 154 moves up and down reciprocally during rotation, thereby driving the rectangular rod 151 to move up and down reciprocally. The arc-shaped plate 142 is used to limit the rotation of the shaft rod 143, thereby realizing the rotational limit of the limit seat 14. The entire limit seat 14 is not in a vertical state, but remains in a state inclined by 15 degrees of the drive module 15. The shaft rod 143 drives the limit seat 14, the fixed clamping rod 141 and the chuck body 20 thereon to rotate, so that multiple small holes on the chuck body 20 can be exposed at multiple angles, facilitating the spraying of the inner wall of the small holes on the chuck body 20 and preventing occlusion.

[0033] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.

Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be encompassed within the present invention. Any reference signs in the claims should not be regarded as limiting the claimed rights.

[0034] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
