[0023] The following is for reference. Figures 1 to 3 Describes a diesel engine flywheel painting apparatus according to an embodiment of this application.

[0024] The diesel engine flywheel painting apparatus according to the first aspect of this application, such as Figure 1 and Figure 3 As shown, a flange 801 is connected to the inner peripheral wall of the flywheel 800.

[0025] refer to Figure 2 and Figure 3 As shown, the diesel engine flywheel painting device includes a support 100 and a painting assembly 200. The support 100 includes a support part 101 and a positioning post 102. The top surface of the support part 101 forms a support surface 103, which can be circular. The positioning post 102 is connected to the support surface 103 and can be coaxial with the support surface 103. The support surface 103 is used to support the bottom surface of the flange 801. The positioning post 102 is used to pass through the flange 801. For example, the center of the flange 801 is generally provided with a mounting hole. The flange 801 is installed on the rotating shaft through the mounting hole, and the positioning post 102 is used to pass through the mounting hole.

[0026] The painting assembly 200 includes a first painting component 201, a second painting component 202, and a third painting component 203. The first painting component 201 is located above the second painting component 202. The first painting component 201 is rotatably connected to the positioning post 102 about the axis of the positioning post 102. The second painting component 202 is rotatably connected to the support part 101 about the axis of the positioning post 102. The two ends of the third painting component 203 are respectively connected to the end of the first painting component 201 away from the positioning post 102 and the end of the second painting component 202 away from the support part 101. After the flywheel 800 is hoisted onto the support 100, the first paint spraying component 201 is located above the flywheel 800, the second paint spraying component 202 is located below the flywheel 800, and the third paint spraying component 203 is located on the outside of the flywheel 800. The first paint spraying component 201 is used to paint the top surface of the flywheel 800, the second paint spraying component 202 is used to paint the bottom surface of the flywheel 800, and the third paint spraying component 203 is used to paint the outer peripheral wall of the flywheel 800.

[0027] In this application, the support surface 103 of the support part 101 supports the bottom surface of the flange 801, and the positioning post 102 passes through the mounting hole at the center of the flange 801 to support and position the flywheel 800. This not only ensures that the flywheel 800 remains stable during the painting process, but also allows for a painting space below the flywheel 800. The painting assembly 200 is rotatable around the axis of the positioning post 102. The painting assembly 200 includes a first painting component 201, a second painting component 202, and a third painting component 203, with the third painting component 203 connected between the first and second painting components 201 and 202. The first painting component 201 is located above the flywheel 800, the second painting component 202 is located below the flywheel 800, and the third painting component 203 is located on the outer side of the flywheel 800. This allows for simultaneous painting of the top, bottom, and outer peripheral walls of the flywheel 800. Compared to manually spraying each surface of the flywheel 800 sequentially with a handheld spray gun, this significantly simplifies the operation process and saves labor and time costs. Furthermore, by rotating the painting assembly, each painting component can evenly and comprehensively spray paint onto the flywheel 800 along its circumference, significantly improving the painting quality of the flywheel 800 surface.

[0028] It should be noted that the paint spraying assembly 200 can be rotated manually or by a servo motor or other drive components, depending on the actual needs.

[0029] refer to Figure 2 and Figure 3 As shown, in some embodiments of this application, the first paint spraying component 201 includes a first paint spraying pipe 204 and a plurality of first nozzles 205. On a projection plane perpendicular to the axis of the positioning post 102, the projection of the first paint spraying pipe 204 extends radially along the positioning post 102. The plurality of first nozzles 205 are disposed on the first paint spraying pipe 204 and arranged along the length direction of the first paint spraying pipe 204, with the spraying direction of the first nozzles 205 pointing downward. For example, the first paint spraying pipe 204 may be connected to a paint delivery pipe 210, and the paint delivery pipe 210 may be connected to a paint supply device.

[0030] In this embodiment, the projection of the first paint spray tube 204 onto the projection plane perpendicular to the axis of the positioning post 102 extends radially along the positioning post 102. Multiple first nozzles 205 are arranged along the length of the first paint spray tube 204 and spray downwards. This allows the multiple first nozzles 205 to simultaneously cover the entire area of ​​the top surface of the flywheel 800 from the inner edge to the outer edge when the first paint spray tube 204 rotates around the axis of the positioning post 102, completing the full painting of the top surface of the flywheel 800 in a single rotation. The radial arrangement of the multiple first nozzles 205 along the flywheel 800 ensures uniform paint coverage at all positions on the top surface of the flywheel 800, avoiding the problem of excessively thick or thin paint in certain areas caused by manual hand-held spraying.

[0031] It should be noted that the first paint spraying component 201 can also be other structures, for example, it can include a mounting bracket and multiple spray guns, with the multiple spray guns mounted on the mounting bracket and spraying in a downward direction.

[0032] refer to Figure 2 and Figure 3 As shown, in some embodiments of this application, the second paint spraying component 202 includes a second paint spraying pipe 206 and a plurality of second nozzles 207. On a projection plane perpendicular to the axis of the positioning post 102, the projection of the second paint spraying pipe 206 extends radially along the positioning post 102. The plurality of second nozzles 207 are disposed on the second paint spraying pipe 206 and arranged along the length direction of the second paint spraying pipe 206, with the spraying direction of the second nozzles 207 facing upward. For example, the second paint spraying pipe 206 may be connected to a paint delivery pipe 210, and the paint delivery pipe 210 may be connected to a paint supply device.

[0033] In this embodiment, the projection of the second paint spray tube 206 onto the projection plane perpendicular to the axis of the positioning post 102 extends radially along the positioning post 102. Multiple second nozzles 207 are arranged along the length of the second paint spray tube 206 with their spray direction upwards. This allows the multiple second nozzles 207 to simultaneously cover the entire bottom surface of the flywheel 800 from its inner edge to its outer edge when the second paint spray tube 206 rotates around the axis of the positioning post 102, completing a full coat of paint on the bottom surface of the flywheel 800 in a single rotation. The radial arrangement of the multiple second nozzles 207 along the flywheel 800 ensures uniform paint coverage at all locations on the bottom surface of the flywheel 800, avoiding the problem of excessively thick or thin paint in certain areas that occurs when manually spraying with a handheld spray gun.

[0034] It should be noted that the second painting component 202 can also be other structures, for example, it can include a mounting bracket and multiple spray guns, with the multiple spray guns mounted on the mounting bracket and spraying in the upward direction.

[0035] refer to Figure 2 and Figure 3 As shown, in some embodiments of this application, the third paint spraying component 203 includes a third paint spraying pipe 208 and a plurality of third nozzles 209. The third paint spraying pipe 208 extends vertically, and the plurality of third nozzles 209 are disposed on the third paint spraying pipe 208 and arranged along the length direction of the third paint spraying pipe 208. The spraying direction of the third nozzles 209 is towards the positioning post 102. For example, the third paint spraying pipe 208 may be connected to a paint delivery pipe 210, and the paint delivery pipe 210 may be connected to a paint supply device.

[0036] In this embodiment, the third paint spray pipe 208 extends vertically, and multiple third nozzles 209 are arranged along the length of the third paint spray pipe 208 with the spray direction facing the positioning post 102. This ensures that when the third paint spray pipe 208 rotates around the positioning post 102, the multiple third nozzles 209 can simultaneously cover the entire height range of the outer peripheral wall of the flywheel 800 from top to bottom, ensuring uniform paint coverage at all heights of the outer peripheral wall of the flywheel 800. The third paint spraying component 203, together with the first paint spraying component 201 and the second paint spraying component 202, constitutes an all-round paint coverage of the top surface, bottom surface, and outer peripheral wall of the flywheel 800, realizing synchronous painting of all outer surfaces of the flywheel 800.

[0037] It should be noted that the third painting component 203 can also be other structures, for example, it can include a mounting bracket and multiple spray guns, with the multiple spray guns located on the mounting bracket and spraying in the direction of the positioning post 102.

[0038] refer to Figure 2 and Figure 3 As shown, in some embodiments of this application, the support 100 further includes a rotating part 104 and a collar 105. The rotating part 104 is rotatably connected to the top of the positioning post 102 about the axis of the positioning post 102. The first paint spraying component 201 is detachably connected to the rotating part 104. The collar 105 is rotatably sleeved on the support part 101 about the axis of the positioning post 102. The second paint spraying component 202 is connected to the collar 105. For example, the first paint spraying component 201 may have a plug-in part, and the rotating part 104 may have a plug hole, with the plug-in part and the plug hole plugging into each other. Of course, the first paint spraying component 201 and the rotating part 104 may also be connected by fasteners.

[0039] In this embodiment, by setting the rotating part 104 and the collar 105, the painting assembly 200 can rotate around the axis of the positioning post 102. The first painting component 201 is detachably connected to the rotating part 104. Thus, when the flywheel 800 to be painted is hoisted onto the support 100 or the painted flywheel 800 is hoisted off the support 100, the first painting component 201 can be separated from the rotating part 104 and moved away from the second painting component 202 to avoid the first painting component 201 interfering with the installation and removal of the flywheel 800.

[0040] refer to Figure 2 and Figure 3 As shown, in some embodiments of this application, the two ends of the third paint spraying component 203 are respectively hinged to the end of the first paint spraying component 201 away from the positioning post 102 and the end of the second paint spraying component 202 away from the support portion 101. For example, the top end of the third paint spraying tube 208 may be hinged to the end of the first paint spraying tube 204 away from the positioning post 102, and the bottom end of the third paint spraying tube 208 may be hinged to the end of the second paint spraying tube 206 away from the positioning post 102.

[0041] In this embodiment, the two ends of the third paint spraying component 203 are respectively hinged to the end of the first paint spraying component 201 away from the positioning post 102 and the end of the second paint spraying component 202 away from the support part 101. When the flywheel 800 to be painted is hoisted onto the support seat 100 or the painted flywheel 800 is hoisted off the support seat 100, the first paint spraying component 201 can be separated from the rotating part 104. Then, the first paint spraying component 201 and the third paint spraying component 203 are rotated so that the first paint spraying component 201 and the third paint spraying component 203 move away from the periphery of the flywheel 800, so as to avoid the first paint spraying component 201 and the third paint spraying component 203 interfering with the installation and removal of the flywheel 800.

[0042] It should be noted that the third paint spraying component 203 may not be connected to the first paint spraying component 201 and the second paint spraying component 202, or it may be connected to both. Furthermore, both ends of the third paint spraying component 203 may be connected to the end of the first paint spraying component 201 furthest from the positioning post 102 and the end of the second paint spraying component 202 furthest from the support portion 101 via a flexible structure, for example, via a flexible tube.

[0043] refer to Figure 2 and Figure 3 As shown, in some embodiments of this application, the diesel engine flywheel painting device further includes a first baffle 300, which is connected to the first painting component 201. The bottom end of the first baffle 300 is used to abut against the outer side of the top surface of the flange 801. The first baffle 300 is configured as an arc plate and extends circumferentially along the positioning post 102. For example, the first baffle 300 extends circumferentially along the positioning post 102, that is, on the projection plane perpendicular to the axis of the positioning post 102, the projection of the first baffle 300 is arc-shaped and extends circumferentially along the axis of the positioning post 102.

[0044] In this embodiment, the first baffle 300 abuts against the outer side of the top surface of the flange 801 during the painting process. The first baffle 300 is configured as an arc plate structure and extends circumferentially along the positioning post 102, so that the first baffle 300 can rotate synchronously with the first painting component 201. During the rotation, it always keeps the top surface of the flange 801 blocked. During the rotation of the first painting component 201, it can effectively prevent the paint sprayed by the first painting component 201 from splashing onto the top surface of the flange 801, ensuring that the top surface of the flange 801 is not contaminated by paint.

[0045] refer to Figure 2 and Figure 3As shown, in some embodiments of this application, the diesel engine flywheel painting device further includes a second baffle 400, which is connected to the second painting component 202. The top end of the second baffle 400 is used to abut against the outer side of the bottom surface of the flange 801. The second baffle 400 is configured as an arc plate, extending circumferentially along the positioning post 102. For example, the second baffle 400 extends circumferentially along the positioning post 102, that is, on the projection plane perpendicular to the axis of the positioning post 102, the projection of the second baffle 400 is arc-shaped and extends circumferentially along the axis of the positioning post 102.

[0046] In this embodiment, the second baffle 400 abuts against the outer side of the bottom surface of the flange 801 during the painting process. The second baffle 400 is configured as an arc plate structure and extends circumferentially along the positioning post 102, so that the second baffle 400 can rotate synchronously with the first painting component 201. During the rotation, it always maintains the shielding of the bottom surface of the flange 801. During the rotation of the second painting component 202, it can effectively prevent the paint sprayed by the second painting component 202 from splashing onto the bottom surface of the flange 801, ensuring that the bottom surface of the flange 801 is not contaminated by paint.

[0047] refer to Figure 2 and Figure 3 As shown, in some embodiments of this application, the diesel engine flywheel painting device further includes a first scraper 500, a second scraper 600, and a third scraper 700. The first scraper 500 is connected to the first painting component 201, and both ends of the first scraper 500 extend to the radial sides of the flywheel 800. The first scraper 500 is used to scrape the paint evenly on the top surface of the flywheel 800. The second scraper 600 is connected to the second painting component 202, and both ends of the second scraper 600 extend to the radial sides of the flywheel 800. The second scraper 600 is used to scrape the paint evenly on the bottom surface of the flywheel 800. The third scraper 700 is connected to the third painting component 203, and both ends of the third scraper 700 extend to the axial ends of the flywheel 800. The third scraper 700 is used to scrape the paint evenly on the outer peripheral wall of the flywheel 800. For example, after the flywheel 800 is installed, there may be a small gap between the bottom surface of the first scraper 500 and the top surface of the flywheel 800, a small gap between the top surface of the second scraper 600 and the bottom surface of the flywheel 800, and a small gap between the side of the third scraper 700 near the positioning post 102 and the outer peripheral wall of the flywheel 800.

[0048] In this embodiment, while the first paint spraying component 201 rotates to spray paint, the first scraper 500 rotates accordingly to smooth the paint just sprayed onto the top surface of the flywheel 800. Similarly, while the second paint spraying component 202 rotates to spray paint, the second scraper 600 rotates accordingly to smooth the paint just sprayed onto the bottom surface of the flywheel 800. And while the third paint spraying component 203 rotates to spray paint, the third scraper 700 rotates accordingly to smooth the paint just sprayed onto the outer peripheral wall of the flywheel 800. This process evenly spreads the accumulated paint, eliminating defects such as paint accumulation or exposed substrate. The scraper not only improves the smoothness and uniformity of the paint film but also helps control the consistency of the paint film thickness, thus improving the overall painting quality of the flywheel 800. Furthermore, the painting and scraping processes are performed simultaneously, eliminating the need for an additional scraping step and further improving production efficiency.

[0049] refer to Figure 2 and Figure 3 As shown, in some embodiments of this application, the third scraper 700 extends vertically, and on the projection plane perpendicular to the axis of the positioning post 102, the projections of the first scraper 500 and the second scraper 600 both extend radially along the positioning post 102.

[0050] In this embodiment, the first scraper 500 and the second scraper 600 extend radially along the flywheel 800, so that during rotation, the first scraper 500 and the second scraper 600 can thoroughly scrape the paint evenly on the top and bottom surfaces from the inner edge to the outer edge of the flywheel 800, respectively, covering the complete annular area. The third scraper 700 extends vertically, so that during rotation, the third scraper 700 can thoroughly scrape the paint evenly from the top to the bottom of the outer peripheral wall of the flywheel 800, covering the entire height range of the outer peripheral wall of the flywheel 800.

[0051] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
