[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] like Figure 1-Figure 8 A mechanical parts spraying device shown in the figure comprises a base 1, a protective shell 101 is fixedly connected to the top of the base 1, a discharge groove 104 is opened on the top of the base 1, a discharge pipe 105 connected to the discharge groove 104 is fixedly connected to one side of the base 1, a motor 102 is arranged inside the base 1, an output shaft of the motor 102 passes through the base 1 and is fixedly connected to a turntable 103 located inside the protective shell 101, a uniformly distributed driving structure 2 is arranged on the surface of the turntable 103, and a spraying structure 3 is arranged on the surface of the protective shell 101;

[0029] Among them, the driving structure 2 includes a guide bar 201 fixedly connected to the inner top wall of the protective shell 101, the cross-sectional shape of the guide bar 201 is arc-shaped, and smooth sections 202 are formed at both ends of the guide bar 201. The surface of the guide bar 201 is provided with a toothed ring section 203 located between the two smooth sections 202.

[0030] The turntable 103 can be driven to rotate by starting the motor 102 , and the mechanical parts to be sprayed are placed on the turntable 103 and driven to the position where the spraying structure 3 is set through the rotation of the turntable 103 for spraying.

[0031] like Figure 1-Figure 8As shown, a connecting ring 204 is fixedly connected to the top of the base 1 , a groove 205 is provided on the top of the connecting ring 204 , a guide plate 206 is fixedly connected to the inner wall of the groove 205 , and guide slopes 207 are provided at both ends of the guide plate 206 .

[0032] The driving structure 2 also includes a plurality of connecting rods 208 rotatably connected to the top of the turntable 103 . The top of the connecting rod 208 is fixedly connected to a driving shaft 209 . The surface of the driving shaft 209 is fixedly connected to a gear 210 . The gear 210 is meshed with the gear ring segment 203 .

[0033] A liquid storage chamber 211 is provided inside the connecting rod 208, and the liquid storage chamber 211 is filled with hydraulic oil. An adjusting chamber 214 connected to the liquid storage chamber 211 is provided inside the connecting rod 208. An extrusion plate 212 is slidably connected to the inner wall of the liquid storage chamber 211, and a push rod 213 is fixedly connected to the bottom of the extrusion plate 212, and the lower end of the push rod 213 passes through the interior of the groove 205.

[0034] The interior of the connecting rod 208 is provided with evenly distributed storage cavities 217, the inner wall of the storage cavity 217 is provided with a through hole 216 connected to the adjustment cavity 214, the inner wall of the storage cavity 217 is slidably connected with a sliding plate 220, the side of the sliding plate 220 away from the through hole 216 is fixedly connected with an adjustment rod 218, and the other end of the adjustment rod 218 passes through the connecting rod 208 and is fixedly connected with an extrusion block 215.

[0035] A spring 219 is sleeved on the surface of the adjustment rod 218 , one end of the spring 219 is fixedly connected to the surface of the sliding plate 220 , and the other end of the spring 219 is fixedly connected to the inner wall of the storage cavity 217 .

[0036] Specifically, the setting position of the guide plate 206 matches the position of the guide strip 201 , and the length of the guide plate 206 is greater than the length of the gear ring segment 203 .

[0037] The arrangement of the connecting rod 208 enables the inner hole of the tubular mechanical part to be placed on the surface of the turntable 103 through the connecting rod 208. As the turntable 103 rotates, the push rod 213 can move along the guide slope 207 to the top surface of the guide plate 206 under the action of the guide slope 207. In this process, the push rod 213 drives the extrusion plate 212 to squeeze the hydraulic oil stored in the liquid storage chamber 211. The squeezed hydraulic oil is injected into the storage chamber 217 through the adjustment chamber 214 and the through hole 216, thereby pushing the sliding plate 220 to drive the adjustment rod 218 to slide out from the inside of the storage chamber 217. It can drive the extrusion block 215 to squeeze the inner hole of the tubular mechanical part from the inside, so as to achieve the effect of automatically limiting the tubular mechanical part. As the turntable 103 moves, the push rod 213 is guided from the guide slope 207 at the other end to the inner bottom wall of the groove 205. In this process, the spring 219 can drive the sliding plate 220 to squeeze the hydraulic oil stored in the storage chamber 217 through the through hole 216 and guide it back to the liquid storage chamber 211 for reuse. There is no need for manual operation by the staff, the operation is simple, and the effect of rapid loading and unloading can be achieved, which effectively improves the work efficiency.

[0038] After the guide plate 206 is used in conjunction with the push rod 213 to limit the mechanical parts, during the rotation of the turntable 103, the gear 210 can move along the smooth section 202 to the toothed ring section 203 and mesh with it. Under the meshing action of the toothed ring section 203 and the gear 210, the gear 210 can be driven to make the drive shaft 209 drive the connecting rod 208 to rotate, thereby driving the adjusting rod 218 and the extrusion block 215 to drive the fixed mechanical parts to rotate, so as to facilitate the subsequent good spraying of the surface of the mechanical parts, making the spraying of the spraying structure 3 more uniform, improving the degree of automation of the equipment, and reducing the cost of use. Compared with the existing equipment that needs to use an independent driving device to drive its rotation direction or use manual changes in the position of mechanical parts to spray at different positions, this method is simpler and effectively improves work efficiency.

[0039] The setting of the smooth section 202 is used to provide sufficient distance between the guide plate 206 and the guide slope 207 to limit and fix the mechanical parts.

[0040] like Figure 1-Figure 8 As shown, the spraying structure 3 includes a mounting plate 301 fixedly connected to the surface of the protective shell 101, a nozzle 303 is arranged on one side of the mounting plate 301, one end of the nozzle 303 penetrates into the inner side of the protective shell 101, a threaded rod 302 is arranged on the surface of the mounting plate 301, one end of the threaded rod 302 is threadedly penetrated through the mounting plate 301 and a scraper 306 located on the inner side of the protective shell 101 is arranged, a limiting rod 305 is fixedly connected to the surface of the scraper 306, and the other end of the limiting rod 305 penetrates out of the mounting plate 301.

[0041] One end of the threaded rod 302 is rotatably connected to the surface of the scraper 306 , and the limiting rod 305 is used to prevent the scraper 306 from being synchronously rotated during the rotation of the threaded rod 302 .

[0042] The spraying structure 3 further includes a collecting box 307 fixedly connected to the inner side of the protective shell 101 . The bottom of the collecting box 307 is connected to a guide pipe 304 , and the other end of the guide pipe 304 extends to the inside of the discharge tank 104 .

[0043] By rotating the threaded rod 302, the distance between the scraper 306 and the mechanical parts can be changed, so that after spraying with the nozzle 303, the overly thick paint is scraped off by the scraper 306 and drips into the collection box 307 and is introduced into the discharge groove 104 through the guide tube 304, wherein the discharge groove 104 can be filled with water to maintain the fluidity of the paint after dripping, avoiding the situation where it is inconvenient to clean up after the paint solidifies. By changing the distance between the scraper 306 and the mechanical parts, the control of different coating thickness requirements can be achieved, thereby improving the spraying effect.

[0044] Working principle: the inner hole of the tubular mechanical part is passed through the connecting rod 208 and placed on the surface of the turntable 103. By starting the motor 102, the turntable 103 can be driven to rotate and the mechanical part can be driven to the position where the spraying structure 3 is set for spraying. By setting the guide slope 207 and the guide plate 206, the position of the push rod 213 can be adjusted. The push rod 213 can move along the guide slope 207 to the top surface of the guide plate 206 under the action of the guide slope 207. In this process, the push rod 213 drives the extrusion plate 212 to squeeze the hydraulic oil stored in the liquid storage chamber 211. The squeezed hydraulic oil is injected into the storage chamber 217 through the adjustment chamber 214 and the through hole 216. This pushes the sliding plate 220 to drive the adjusting rod 218 to slide out from the inside of the storage chamber 217, so that it can drive the extrusion block 215 to squeeze the inner hole of the tubular mechanical parts from the inside, thereby achieving the effect of automatically limiting the tubular mechanical parts. As the turntable 103 moves, the push rod 213 is guided from the guide slope 207 at the other end to the inner bottom wall of the groove 205. During this process, the spring 219 can drive the sliding plate 220 to squeeze the hydraulic oil stored in the storage chamber 217 through the through hole 216 and guide it back to the inside of the liquid storage chamber 211 for reuse. There is no need for manual operation by the staff, the operation is simple, and the effect of rapid loading and unloading can be achieved, which effectively improves the work efficiency.
