[0019] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

In addition, the terms "first", "second", "third" and the like are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0021] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, a movable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] like Figure 1 - Figure 5As shown, in this embodiment, a car wheel hub spraying device includes a workbench 1, a sliding groove 2 and an adjustment component, characterized in that: the adjustment component includes a fixing frame 3; a built-in motor 4 is fixedly connected inside the fixing frame 3; the output shaft of the built-in motor 4 is fixedly connected to a half-toothed shaft 5 through a coupling; the adjustment component also includes an auxiliary slide rail 6; an adjusting tooth plate 7 is slidably connected inside the auxiliary slide rail 6; the top of the adjusting tooth plate 7 is fixedly connected to an upper tooth; the surface of the adjusting tooth plate 7 is provided with inner teeth adapted to the half-toothed shaft 5; the surface of the fixing frame 3 is fixedly connected to a supporting clamping shaft 8; the The surface of the supporting card shaft 8 is rotatably connected to a reciprocating plate 9; the surface of the bottom of the reciprocating plate 9 meshes with the upper teeth on the top of the adjusting tooth plate 7; the top of the workbench 1 is fixedly connected to an arc frame 10; the surface of the arc frame 10 is slidably connected to a spray nozzle 11; the surface of the spray nozzle 11 is fixedly connected to a connecting rod 12; the end of the connecting rod 12 away from the spray nozzle 11 is fixedly connected to the surface of the reciprocating plate 9; the inside of the sliding groove 2 is slidably connected to a feeding card table 13; the top of the feeding card table 13 is rotatably connected to a rotating table 14; the top of the rotating table 14 is clamped with a wheel hub 15 to be sprayed.

[0023] Through the above technical solution, the sliding groove 2 is opened inside the workbench 1 for placing the feeding card table 13. Before spraying, the wheel hub 15 to be sprayed is placed on the rotating table 14, and the rotating table 14 is placed on the feeding card table 13, so that the wheel hub 15 to be sprayed is sent to the arc frame 10 by the feeding card table 13 for spraying. In order to avoid the existence of a dead angle for spraying during spraying, the built-in motor 4 drives the half-tooth shaft 5 to start rotating through the output shaft. The half-tooth shaft 5 cooperates with the internal teeth, and the internal teeth are symmetrically and evenly arranged inside the adjusting tooth plate 7. The rotation of the half-tooth shaft 5 drives the internal teeth to move left and right, thereby driving the adjusting tooth plate 7 to move back and forth on the auxiliary slide rail 6. After the adjustment tooth plate 7 moves, the upper teeth drive the reciprocating plate 9 to rotate back and forth left and right, and then drive the spray nozzle 11 to rotate in an arc shape on the arc frame 10 through the connecting rod 12, so as to perform multi-directional spraying. There is no need to install multiple nozzles, nor to adjust the spacing between the nozzles according to needs, which improves the adaptability of use. Here, the reciprocating plate 9 is supported by the supporting card shaft 8 to ensure that the reciprocating plate 9 can rotate normally. In addition, in addition to the spray nozzle 11 being able to slide on the arc frame 10, the wheel hub 15 to be sprayed can rotate with the rotation of the rotating table 14 to adjust the spray surface of the wheel hub 15 to be sprayed and improve the effect of spraying.

[0024] like Figure 2 and Figure 3As shown, the bottom of the fixed frame 3 is fixedly connected to one side of the top of the workbench 1; the sliding groove 2 is opened inside the workbench 1; the bottom of the auxiliary slide rail 6 is fixedly connected to the top of the workbench 1; the surface of one side of the feeding card table 13 is fixedly connected with a hydraulic rod 16; the end of the hydraulic rod 16 away from the feeding card table 13 is fixedly connected to the inner wall of the sliding groove 2; the side of the inner wall of the sliding groove 2 away from the hydraulic rod 16 is fixedly connected with a spring telescopic rod 17; one end of the spring telescopic rod 17 is fixedly connected with a buffer pad 18.

[0025] Through the above technical scheme, the fixed frame 3 is fixed on one side of the top of the workbench 1, the sliding groove 2 is opened inside the workbench 1, the auxiliary slide rail 6 is set on the top of the workbench 1, and the hydraulic rod 16 is fixed inside the sliding groove 2. The hydraulic rod 16 drives the feeding card table 13 to move. When moving, the other side of the feeding card table 13 is against the buffer block 18 of the spring telescopic rod 17. The spring telescopic rod 17 will be extended and retracted when it is subjected to force, and it will recover its deformation after being subjected to force to give a reaction force to the buffer block 18, so that the buffer block 18 buffers and limits the feeding card table 13 to prevent the feeding card table 13 from colliding when feeding.

[0026] like Figure 3 and Figure 4 As shown, a transmission motor 19 is fixedly connected inside the feeding card platform 13 ; the output shaft of the transmission motor 19 is fixedly connected to a transmission shaft 20 via a coupling; the top end of the transmission shaft 20 is fixedly connected to the bottom of the rotating platform 14 .

[0027] Through the above technical solution, the transmission motor 19 is arranged inside the feeding card table 13, and when the transmission motor 19 is working, it drives the transmission shaft 20 to start rotating through the output shaft. After the transmission shaft 20 rotates, it drives the rotating table 14 to start rotating, and then drives the wheel hub to be processed to rotate, so as to achieve the function of adjusting the spray surface of the wheel hub to be processed, and can spray the wheel hub to be processed more comprehensively, further improving the effect of spraying.

[0028] Finally, it should be noted that the above implementation cases are only used to illustrate the present invention, rather than to limit the technical solutions described in the present invention; therefore, although this specification has described the present invention in detail with reference to the above-mentioned embodiments, ordinary technicians in this field should understand that the present invention can still be modified or replaced by equivalents, and all technical solutions and improvements that do not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention; the technology not described in detail in the present invention is implemented with the existing technology.
