Description

Technical Field

[0001] The present invention relates to the technical field of spraying equipment, and in particular to a wheel hub spraying device. Background Art

[0002] In the automotive and parts manufacturing sectors, wheels not only support the vehicle body and transmit power, but the quality of their surface coating also directly impacts the vehicle's aesthetics, corrosion resistance, and service life. However, common wheel coating systems currently on the market present numerous challenges that require urgent resolution, severely hindering improvements in wheel production quality and efficiency.

[0003] On the one hand, traditional wheel hub spraying equipment mostly uses a single fixed spray mode, leaving the wheel hub stationary or capable of only simple single-directional rotation during the spraying process. This makes it difficult to evenly coat the wheel hub surface with paint, leading to uneven coating thickness, dripping, and missed areas. This is particularly true in areas with complex wheel hub structures, such as edges and grooves, where spraying results are particularly poor. This not only affects the wheel hub's appearance but also reduces its protective performance, increases the defective rate, and raises production costs.

[0004] On the other hand, existing spraying equipment has low spraying efficiency. Most equipment can only spray a single wheel hub at a time. After spraying a wheel hub, it is necessary to wait for the spraying to be completed and removed before placing a new wheel hub for the next round of spraying, which makes continuous operation impossible. In the context of large-scale automobile production, this inefficient spraying method seriously affects production progress and is difficult to meet the efficient needs of automobile manufacturers for mass production of wheels. In addition, although some equipment has a certain degree of assembly line operation capability, the spraying and loading and unloading processes interfere with each other, resulting in a less smooth overall production process and further reducing production efficiency.

[0005] In summary, the development of a wheel hub spraying device that can achieve uniform paint spraying, has efficient flow operation capabilities and a high degree of automation has become an urgent need to improve the quality and efficiency of wheel hub production and promote the development of the automotive parts manufacturing industry. The wheel hub spraying device of the present invention came into being based on this background. Summary of the Invention

The already coated wheel hubs can then be promptly removed and replaced with new ones. Each link is tightly integrated and independent of each other, forming a continuous spraying line. This significantly improves spraying efficiency, meets the automotive industry's demand for efficient mass production of wheel hubs, and reduces production costs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0037] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0038] like Figures 1-12 As shown, a wheel hub spraying device provided by an embodiment of the present invention includes a base 101, a vertical plate 102 is fixedly installed on the upper surface of the base 101, an outer wall of the vertical plate 102 is provided with a mounting hole 104, and a disc 103 is rotatably connected to the mounting hole 104, an annular groove 105 is provided on the outer side of the disc 103, and the annular groove 105 and the mounting hole 104 cooperate with each other, the outer wall of the disc 103 is also provided with fixing holes distributed in an annular shape at equal distances, and a rotating member 106 is rotatably connected to the fixing hole, and further includes: a clamping mechanism, the clamping mechanism is provided in the rotating member 106, and is used to clamp and fix the wheel hub to be sprayed on the outer side of the rotating member 106; a driving mechanism, the driving mechanism is provided on the outer side of the vertical plate 102, and is used to drive the disc 103 to rotate on the vertical plate 10 2 rotation; a rotation mechanism, which is arranged on the outside of the vertical plate 102, and is used to cause the rotating member 106 to rotate when the disc 103 rotates; a spraying mechanism, which is arranged on the upper surface of the base 101, and is used to spray the hub fixed to the outside of the rotating member 106. The spraying mechanism includes a robotic arm body 201 fixedly mounted on the upper surface of the base 101. In this embodiment, the robotic arm body 201 includes an upper arm, a lower arm, a wrist and other parts, which are connected through joints to form a multi-degree-of-freedom motion structure, which can realize the extension, rotation, pitch and other movements of the robotic arm, thereby imitating the joints of the human arm. A spray hood 202 is fixedly mounted at the end of the robotic arm body 201, and a nozzle 203 is fixedly mounted in the spray hood 202, and the nozzle 203 is L-shaped.

[0039] When the wheel hub needs to be sprayed, the wheel hub can be placed on the outside of the rotating member 106, and then the wheel hub can be clamped and fixed on the outside of the rotating member 106 by the clamping mechanism. At the same time, the disc 103 is driven to rotate in the vertical plate 102 by the driving mechanism. During the rotation process, the spray hood 202 can be driven to move by the mechanical arm body 201, so that the spray hood 202 is connected to the outside of the rotating member 106, and the spray hood 202 is controlled to rotate with the disc 103 with the help of the mechanical arm body 201. At this time, the paint can be introduced into the nozzle 203, so that the paint is sprayed out through the L-shaped nozzle 203 and acts on the surface of the wheel hub, thereby realizing the spraying operation on the wheel hub, and when the disc 103 rotates, the rotation mechanism The use can also make the rotating part 106 rotate, and then make the wheel hub rotate itself when it revolves around the center line of the disk 103. The continuously rotating wheel hub can make the paint act on the wheel hub surface more evenly, and the spraying effect is better. When one group of wheel hubs is sprayed, the spraying mechanism can quickly continue to spray the wheel hubs outside other rotating parts 106, and the wheel hubs that have been sprayed can be removed from the outside of the rotating part 106 and replaced with other wheel hubs to be sprayed, effectively realizing the flow-type circulation spraying operation of the wheel hub and effectively improving the spraying efficiency. Furthermore, when the spray hood 202 is connected to the outside of the rotating part 106, it can also effectively prevent the sprayed paint from spreading to the surroundings, and the use effect is better.

[0040] As an embodiment of the present invention, please refer to Figure 1 、 Figure 2 and Figure 12 The outer wall of the nozzle 203 is connected to the atomizing nozzles 204 distributed at equal distances. A connecting pipe 205 connected to the nozzle 203 is fixedly installed on the outside of the spray hood 202, and a material guide pipe 206 is connected to the end of the connecting pipe 205. The spray hood 202 can be driven to move by the mechanical arm 201, so that the spray hood 202 is connected to the outside of the rotating member 106, and the spray hood 202 is controlled to rotate with the disc 103 by means of the mechanical arm 201, and the paint can be introduced into the nozzle 203 through the material guide pipe 206. The paint is sprayed into atomized form by the atomizing nozzle 204 and acts on the surface of the wheel hub, which can make the sprayed paint more dispersed and uniform. At this time, under the action of the rotation mechanism, the wheel hub rotates together with the rotating part 106, so that the paint can act evenly on the surface of the wheel hub, and the spraying effect is better. When one group of wheel hubs is sprayed, the spray hood 202 can be quickly aimed at another group of wheel hubs by controlling the mechanical arm body 201, and the disc 103 always keeps a uniform rotation state, which can effectively improve the spraying efficiency and achieve better use effect.

[0041] As an embodiment of the present invention, please refer to Figure 7 、 Figure 8 and Figure 9The clamping mechanism includes a rotating shaft 301, a mounting hole is provided on the outer wall of the rotating member 106, and the rotating shaft 301 is rotatably arranged in the mounting hole, a turntable 302 is fixedly installed on the end of the rotating shaft 301, and a sliding groove 303 is provided on the outer wall of the rotating member 106, which is equidistant and annularly distributed, and a limiting groove 304 is provided on the inner wall of the two sides of the sliding groove 303, a circular plate 305 is slidably provided in the limiting groove 304, and a clamping rod 306 is fixedly installed on the outer wall of the circular plate 305, and the outer wall of the turntable 302 is rotatably connected to the connecting rod 307 through the ear seat, and the connecting rod 307 The end portion is connected to the outer wall of the clamping rod 306, and a rotating assembly is further provided on the outside of the rotating member 106 for driving the rotating shaft 301 to rotate. When the wheel hub is placed on the outside of the rotating member 106, the rotating shaft 301 can be driven to rotate by means of the rotating assembly, and the rotating shaft 301 drives the turntable 302 to rotate. The turntable 302 can drive the clamping rod 306 to move with the help of the connecting rod 307, pushing the clamping rod 306 outward, so that all the clamping rods 306 are against the inner wall of the wheel hub, which can quickly clamp and fix the wheel hub, and is very convenient to use.

[0042] As an embodiment of the present invention, please refer to Figure 7 、 Figure 8 and Figure 9 The rotating assembly includes a fixed rod 401 fixed to the outer wall of the rotating member 106 in an annular shape at equal distances, and a torque motor 402 is fixedly installed at the end of the fixed rod 401, and the output end of the torque motor 402 is rotatably connected to the runner 403, and a sleeve 404 is fixedly installed on the outer wall of the runner 403, and the sleeve 404 is sleeved on the outer side of the rotating shaft 301, and a fixed plate 405 is fixedly installed on the outer wall of the rotating shaft 301, and a torsion spring 406 is sleeved on the outer side of the sleeve 404, one end of the torsion spring 406 is connected to the fixed plate 405, and the other end of the torsion spring 406 is connected to the runner 403. When the rotating shaft 301 needs to be rotated, the torque motor 402 can be used to drive the runner 403 03 rotates, the rotating wheel 403 drives the sleeve 404 to rotate outside the rotating shaft 301, and under the connecting action of the torsion spring 406, the rotating shaft 301 and the sleeve 404 can rotate together. When the clamping rod 306 contacts the inner wall of the hub, as the sleeve 404 rotates further, the torsion spring 406 between the rotating wheel 403 and the fixed plate 405 can be twisted, thereby applying a certain torsional force to the rotating shaft 301, prompting the clamping rod 306 to apply a certain clamping force to the hub, and the torsional force increases steadily with the deformation of the torsion spring 406, which also makes the clamping force increase steadily, which can effectively avoid the risk of deformation of the hub caused by excessive clamping force, and the use effect is better.

[0043] As an embodiment of the present invention, please refer to Figure 7 、 Figure 8 and Figure 9A rubber sleeve 308 is also fixedly installed on the outside of the clamping rod 306. Under the action of the rubber sleeve 308, the clamping rod 306 can be prevented from directly contacting the inner wall of the wheel hub to cause wear, and the use effect is better.

[0044] As an embodiment of the present invention, please refer to Figure 3 、 Figure 4 and Figure 7 The driving mechanism includes a bracket 501 fixedly arranged on the outer wall of the vertical plate 102, and a driving motor 502 is fixedly installed at the end of the bracket 501.

The outer side of the disc 103 is provided with teeth grooves 504 distributed in an annular shape at equal distances, and the gears 503 and the teeth grooves 504 are meshed. When the disc 103 needs to be rotated, the gear 503 can be driven to rotate by the driving motor 502. Since the gear 503 and the teeth grooves 504 on the outer side of the disc 103 are meshed, the disc 103 can be driven to rotate in the vertical plate 102, which is very convenient to use.

[0045] As an embodiment of the present invention, please refer to Figure 4 and Figure 5 The rotation mechanism includes a rubber ring 601 fixedly arranged on the outside of the rotating member 106, and the outer wall of the vertical plate 102 is fixedly installed with support rods 602 distributed at equal distances, and the end of the support rod 602 is fixedly installed with an arc member 603, and the central axis of the arc member 603 is consistent with the central axis of the disk 103. The outer side of the rubber ring 601 fits with the inner wall of the arc member 603. When the rotating member 106 rotates with the disk 103, the rubber ring 601 on the outside of the rotating member 106 will fit with the inner wall of the arc member 603. Under the action of the friction between the rubber ring 601 and the arc member 603, the rotating member 106 can rotate together with the disk 103 when it rotates, thereby making the subsequent spraying of the wheel hub on the outside of the disk 103 more uniform and the use effect better.

When the device is used for a long time, it is usually necessary to clean the paint attached to the surface of the disc 103. At this time, a special cleaning agent for cleaning the paint can be sprayed directly onto the surface of the disc 103, and the excess cleaning agent can be collected by the collecting bucket 702 and diverted to the waste collecting box 701 under the action of the scraper 703, making the cleaning process of the device more convenient and the use effect better.

This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
