[0016] In order to make the purpose, technical scheme and advantage of the present application more clear, the technical scheme in the embodiment will be described clearly and completely in the following with the drawings in the embodiment, obviously, the described embodiment is only a part of the present application, not all the embodiments. Based on the given embodiment, all other embodiments obtained by those skilled in the art without making creative labor belong to the scope of protection of the present application.

[0017] In the description of the present application, it needs to be understood that the orientation or position relationship indicated by the terms "up", "down" and the like is based on the orientation or position relationship shown in the drawings, only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, therefore it cannot be understood as a limitation to the present application.

[0018] In the description of the present application, the terms "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying relative importance or implying the number of indicated technical features.

[0019] For details Figures 1-4 As shown in the drawings, the present application discloses a kind of street lamp pole paint spraying device, including base 10, main shaft component 20, tailstock component 30, spraying assembly 40 and straight reciprocating motion component 50;Wherein, main shaft component 20 and tailstock component 30 are fixedly installed on base 10;Main shaft component 20 includes main shaft base 24, main shaft 22, first chuck 25 fixedly connected to main shaft and power component, power component includes main shaft motor 21 and transmission component 23, the power of main shaft motor 21 is driven main shaft 22 and first chuck 25 rotation by transmission component 23;Wherein can preferably transmission component 23 is belt transmission component, it includes respectively fixedly installed on main shaft motor 21 and main shaft 22 belt pulley and transmission belt.Tailstock component 30 includes tailstock 31, ejector rod 32 and second chuck 33, tailstock 31 is provided with ejector cylinder or oil cylinder, of course, it can also be hand-operated screw rod structure, specific details see existing machine tool spindle structure and machine tool tailstock structure, this embodiment is no different from it, here no longer repeat;First chuck 25 in the embodiment and second chuck 33 are coaxial, the street lamp pole to be sprayed is placed between first chuck 25 and second chuck 33 by travelling crane hoisting, by the ejecting of second chuck 33, realize the street lamp pole clamping between first chuck 25 and second chuck 33, after starting main shaft motor 21, it can drive street lamp pole to rotate according to set speed;Of course, since street lamp pole is hollow pole structure, in order to be able to realize reliable clamping and axial self-centering of street lamp pole, first chuck 25 front end in the embodiment is provided with first tapered section 251, second chuck 33 front end is provided with second tapered section 331, to realize the clamping of fast self-centering.In addition, preferably, first annular protrusion 252 is arranged on the rear end of first tapered section 251 in first chuck 25;Second annular protrusion 332 is arranged on the rear end of second tapered section 331 in second chuck 33, by first annular protrusion 252 and second annular protrusion 332, for some hollow error greater street lamp pole, reliable stable clamping and axial limiting can be realized.

[0020] The spraying assembly 40 in this embodiment includes a circular bracket 41 and a plurality of nozzles 42 radially distributed along the circular bracket 41, with the nozzles 42 facing the center of the circular bracket 41. It should be noted that the number of nozzles 42 is adaptively selected and adjusted according to the actual installation space and spraying requirements. The linear reciprocating motion assembly 50 drives the spraying assembly 40 to move axially along the first chuck 25 and the second chuck 33. Of course, in order to ensure that the nozzle 42 can smoothly spray paint or coating materials, it is preferable that the nozzle 42 is connected to a pressurized air source and a paint storage tank via a pipeline at the end away from its outlet. Similar to the principle of a traditional spray gun, the pressurized air source blows out from the outlet of the nozzle 42, creating a negative pressure in the channel connecting the spray gun and the paint storage tank. This draws the paint to the outlet of the nozzle 42, where it is atomized and carried out by the high-speed airflow, adhering to the surface of the street light pole. The radially distributed nozzles can cover the surface of the street light pole as much as possible. At the same time, the rotation of the street light pole driven by the main shaft assembly further makes the coating thickness of the street light pole more uniform, improving its coating uniformity.

[0021] Furthermore, considering the need to facilitate the loading and unloading of the streetlight pole 60, in this embodiment, it is preferable that, after spraying or in standby mode, the initial position of the spraying assembly 40 is located behind the second clamp 33. That is, the spraying assembly 40 completely clears the space between the first and second clamps, avoiding interference and collisions during the loading and unloading of the streetlight pole. During the spraying process, the spraying assembly 40, driven by the linear reciprocating motion assembly 50, begins spraying from the end of the streetlight pole near the second clamp 33 and ends near that end. Figure 4 The 40' in the figure indicates the spraying component that is halfway through its movement. Of course, it is possible to appropriately exceed the position of the first or second chuck to end or begin spraying. In order to avoid interference and collision between the nozzle 42 and the equipment on the path, this embodiment preferably has a minimum distance between the nozzles 42 that is greater than the maximum diameter of the first chuck 25 and the second chuck 33, so that it can perform spraying smoothly and return to the initial position smoothly after spraying is completed.

[0022] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
