Working principle: when the servo motor II is started, the output power of the servo motor II drives the driving gear to start rotating, the driving gear is accurately meshed with a gear at the bottom of the gear frame, so that relative rotation between the gear frame and the fixed ring is caused, the gear frame rotates and drives the driven gear to rotate, the driven gear passively rotates through rotation of the gear frame, torque is transmitted to the rack through meshing transmission when the driven gear rotates, the rack reciprocates along the tangential vertical direction of the fixed ring, the movement of the rack drives a plurality of clamping plates to change the distance, the clamping plates are key components for clamping the case, the diameter range of the case which can be clamped is directly determined by the distance change between the clamping plates, when the rack moves, the clamping plates are pushed to move inwards or outwards, so that clamping of the case with different diameters is realized, and the rotation of the telescopic rod is brought by starting of the servo motor I. The telescopic function of the telescopic rod endows the miniature motor with the height adjusting capability, so that the telescopic rod can flexibly adapt to the inner wall shape of various complex casing bodies, and when the miniature motor starts to rotate, the screw rod also rotates. The screw rod is precisely matched with the nut, the nut can move left and right along with the rotation of the screw rod, the nut is realized under the precise limiting action of the first slide block of the chute, the stability and accuracy of the movement of the nut are ensured, the movement of the nut drives the left and right movement of one end of the inclined rod, which is contacted with the slide block, of the slide block, the included angle of the flow limiting boxes at two sides can be changed, the design of the flow limiting boxes is skillfully and fixedly connected with the spray head, when the included angle of the flow limiting boxes is changed, the angle of the sprayed paint inside the spray head is changed, the paint spraying system can adapt to the machine box bodies with inner walls of different curved surfaces, no matter the machine box bodies are in complicated curves or steep angles, the spray head can accurately spray paint, the even coating of the inner walls of the machine box bodies is ensured, the utilization rate of the paint is improved, the coating quality of the inner walls of the machine box bodies is improved, the design essence of the flow regulating assembly is the ingenious application of the contraction rod and the blocking cone, the combination of the contraction rod and the blocking cone, the contraction rod can be used for realizing incomparable flexibility, and the precise control of the distance between the blocking cone and the blocking wall through carefully regulating the length of the blocking rod, so that the flow can be used for continuously and leading the flow to enter into the flow limiting and flow to be stopped and stopped by the blocking the flow limiting box. The barrier wall, like a sound commander, accurately shunts fluid into each of the different flow paths. In each runner, the fluid flows out through the water drain, which is a process of preliminarily adjusting the flow rate, ensuring uniform distribution and preliminary control of the fluid, and in the process, the shrinkage rod and the baffle cone silently keep their posts in the initial position without any additional influence on the flow rate of the fluid. However, once we need to fine-tune the flow, the external driving mechanism will be straight out, driving the contraction rod to stretch and retract, and the baffle cone will move flexibly in the flow channel along with the expansion and contraction of the contraction rod, as if one dancer dances on the stage gracefully. The movement of the baffle cone changes the sectional area of the flow channel, just like an intangible valve is regulated, thereby realizing the dynamic regulation of the fluid flow, when the baffle cone moves towards the center of the flow channel, the sectional area of the flow channel gradually decreases, and the flow rate of fluid naturally decreases as if the flow channel is a gradually narrowed river, otherwise, when the baffle cone moves outwards, the sectional area of the flow channel is increased, the fluid flow rate is correspondingly increased, the subtle adjusting mechanism enables the flow adjusting component to cope with various complex fluid control requirements, the excellent performance and flexibility are presented, when the baffle cone moves towards the edge of the flow channel, the sectional area of the flow channel is increased, the fluid flow rate is increased, thereby realizing different coating flow rate restrictions on the upper end and the lower end of the flow limiting box, after the paint with higher fluidity is considered to flow due to gravity, the uniform paint on the outer wall of the casing body is realized, the rotary column I is rotatably connected in the fixing piece, the rotary column I is uniquely designed, and can freely rotate in a certain range through the rotary connection with the fixing piece, so that the possibility is provided for flexible adjustment of the system, the rotary column II is rotatably connected in the rotary column I, the nested structural design is realized, the connecting component can realize multi-level flexible adjustment while keeping the whole stable, the rotation range of the rotating column II is limited by the rotating column I, but maintains independence to a certain extent, one side of the outer wall of the second rotating column is rotationally connected with one end of the third rotating column, the third rotating column is the most flexible part in the whole connecting assembly, the other end of the third rotating column is fixedly connected with a connecting block, the connecting block can be connected with a synchronous box, and when the outer walls are mechanically connected, the interior can be used for completing the transmission of the coating through the hose, so that the synchronous spraying of the inner wall and the outer wall of the casing is completed.
The invention provides a machine case coating spraying device. The beneficial effects are as follows:
1. According to the invention, through the precise matching of the servo motor, the telescopic rod, the micro motor, the screw rod, the current limiting box and other parts, the flexible adjustment of the spray head coating angle is realized, and an efficient and uniform coating spraying solution is provided for the casing bodies of the inner walls of different curved surfaces.
2. According to the invention, as the contraction rod stretches, the blocking cone moves in the flow channel, and the sectional area of the flow channel is changed, so that the dynamic adjustment of the fluid flow is realized, and when the blocking cone moves towards the center of the flow channel, the sectional area of the flow channel is reduced, and the fluid flow is reduced; when the blocking cone moves towards the edge of the flow channel, the sectional area of the flow channel is increased, and the fluid flow is increased, so that the flow of the coating sprayed on the upper end and the lower end of the outer wall of the casing body is changed, and the uniform spraying of the inner wall and the outer wall of the casing body is realized after the coating with high fluidity flows.
3. According to the invention, through the cooperative work of the servo motor II, the gear, the rack, the clamping plate and other parts, the accurate clamping of the case bodies with different diameters is realized, and the adaptability of the sprayable case body is improved.
4. According to the invention, through the connection function of the connection component, the flow communication of the internal coating liquid is completed through the internal hose while the mechanical connection of the outer wall of the synchronous box of the current-limiting box is realized, the synchronous spraying of the inner wall and the outer wall of the casing is realized, and the working efficiency is improved.
