Abstract
Description
Technical Field
[0001] This utility model belongs to the field of spraying equipment, and relates to a spraying device for vehicle chassis. Background Technology
[0002] A vehicle chassis spraying equipment is a mechanical device specifically designed for spraying automotive chassis. Its main function is to uniformly spray anti-rust paint, chassis armor, and other materials onto the chassis surface to enhance the chassis's corrosion resistance, rust prevention, sound insulation, and impact resistance. It uses compressed air, electric, or hydraulic drives to provide power for paint delivery and spraying, ensuring that the paint is sprayed out at appropriate pressure and flow rate.
[0003] Existing spraying equipment causes excess paint to drip during operation, which not only increases the company's raw material costs but also results in a huge waste of resources. At the same time, the dripping paint splashes and accumulates everywhere in the work area, polluting the workshop floor, equipment surfaces, and other working environments. Harmful substances in the paint volatilize into the air, forming harmful gases. These harmful gases not only pollute the air quality in the workshop but also spread to the surrounding environment with air currents, adversely affecting the surrounding ecological environment. Utility Model Content
[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a spraying device for vehicle chassis that can effectively collect dripping paint.
[0005] The objective of this utility model can be achieved through the following technical solutions:
[0006] A painting device for a vehicle chassis includes a displacement truss, characterized in that a vehicle body to be painted is suspended at the lower end of the displacement truss, and an anti-drip overflow base plate is installed at the lower end of the vehicle body to be painted. The anti-drip overflow base plate includes multiple individual connecting matching plates, and the anti-drip overflow base plate is spliced together from four individual connecting matching plates. First corrugated telescopic plates are fixedly connected to the left and right inner walls of each individual connecting matching plate. Two semi-circular inner sliders are fixedly connected between two of the first corrugated telescopic plates. The two semi-circular inner sliders are slidably connected to the front and rear inner walls of the individual connecting matching plates. Second arc-shaped corrugated telescopic plates are symmetrically fixedly connected to the front and rear sides of corresponding two semi-circular inner sliders. A centrally opened circumferential block is fixedly connected to the lower center of the second arc-shaped corrugated telescopic plate. An extension rod nozzle penetrates the inner end of the centrally opened circumferential block, and an electromechanical arm is installed at the lower end of the extension rod nozzle.
[0007] In the above-mentioned painting equipment for vehicle chassis, the lower end of the electromechanical arm is fixedly connected to a mechanical arm base, and the two sets of single connecting matching plates on the left and right are inclined to each other.
[0008] In the above-mentioned spraying equipment for vehicle chassis, a waste liquid collection hole is provided at the inclined position between the two sets of individual connecting matching plates, and a liquid guiding vertical pipe is fixedly connected to the lower end of the waste liquid collection hole.
[0009] In the above-mentioned spraying equipment for vehicle chassis, the lower end of the liquid guiding vertical pipe is fixedly connected to a liquid accumulation tank, and dustproof baffles are fixedly connected to both the front and rear ends of the anti-drip overflow base plate.
[0010] In the above-mentioned spraying equipment for vehicle chassis, the two dust baffles are located on the front and rear sides of the vehicle body to be sprayed, respectively, and the upper end of the displacement truss is fixedly connected to the purification main pipe.
[0011] In the above-mentioned spraying equipment for vehicle chassis, the lower end of the purification main pipe is symmetrically fixed with air intake ports on both the left and right sides, and the purification main pipe is externally connected to a purification system.
[0012] In the above-mentioned spraying equipment for vehicle chassis, the four individual connecting matching plates are evenly partitioned below the anti-drip overflow base plate, and the overall installation effect of the anti-drip overflow base plate is tilted to the left by five degrees.
[0013] Compared with existing technologies, this vehicle chassis painting equipment uses a displacement truss to stably hoist the vehicle body to be painted, providing a reference positioning for painting. The anti-drip overflow base plate is spliced from a single connecting matching plate and tilted at five degrees, allowing dripping paint to collect to the left due to gravity. The first corrugated telescopic plate and the semi-circular inner slider form an adjustable structure, which, together with the second arc-shaped corrugated telescopic plate, allows the centrally opened ring block to drive the extension rod nozzle to move in multiple dimensions. Combined with the motion control of the electro-mechanical arm, precise painting of the vehicle chassis is achieved. The waste liquid collection system, consisting of waste liquid collection holes, liquid guide vertical pipes, and liquid accumulation tanks, can effectively collect dripping paint, preventing pollution and waste. The dust baffle can block splashing paint, improving the cleanliness of the working environment. The purification main pipe is connected to the purification system through the air intake expansion port, which can treat harmful gases and atomized particles generated during painting, ensuring air quality and ensuring that the overall painting operation is efficient, environmentally friendly, and safe.

[0022] like Figure 1As shown in Figure 4, the painting equipment for vehicle chassis includes a displacement truss 1. A vehicle body 18 to be painted is suspended at the lower end of the displacement truss 1. An anti-drip overflow base plate 2 is installed at the lower end of the vehicle body 18. The anti-drip overflow base plate 2 includes multiple individual connecting and matching plates 5. The anti-drip overflow base plate 2 is composed of four individual connecting and matching plates 5 spliced together. First corrugated telescopic plates 6 are fixedly connected to the left and right inner walls of each individual connecting and matching plate 5. Two of the first corrugated telescopic plates 6... Two semi-circular inner sliders 7 are fixedly connected between them. The two semi-circular inner sliders 7 are slidably connected to the front and rear inner walls of a single connecting matching plate 5. A second arc-shaped corrugated telescopic plate 8 is symmetrically fixedly connected between the front and rear sides of the two corresponding semi-circular inner sliders 7. A centrally opened circumferential block 9 is fixedly connected to the lower middle part of the second arc-shaped corrugated telescopic plate 8. An extension rod nozzle 15 passes through the inner end of the centrally opened circumferential block 9. An electric robotic arm 14 is installed at the lower end of the extension rod nozzle 15.
[0023] The lower end of the electric robotic arm 14 is fixedly connected to the robotic arm base 13, and the two sets of single connecting matching plates 5 on the left and right are inclined to each other.
[0024] Waste liquid collection holes 10 are provided at the inclined positions between the two sets of individual connecting matching plates 5, and a liquid guiding vertical pipe 11 is fixedly connected to the lower end of the waste liquid collection hole 10.
[0025] The lower end of the liquid guiding vertical pipe 11 is fixedly connected to the liquid accumulation tank 12, and the front and rear ends of the anti-drip overflow base plate 2 are both fixedly connected to the dustproof baffles 4.
[0026] The two dustproof baffles 4 are located on the front and rear sides of the vehicle body 18 to be painted, respectively, and the upper end of the displacement truss 1 is fixedly connected to the purification main pipe 16.
[0027] The lower end of the purification main pipe 16 is symmetrically fixed with air intake ports 17 on both the left and right sides, and the purification main pipe 16 is connected to a purification system.
[0028] The four individual connecting matching plates 5 are evenly spaced below the anti-drip overflow base plate 2, and the overall installation effect of the anti-drip overflow base plate 2 is tilted to the left by five degrees.
[0029] In this scheme, the displacement truss 1 first hoists the vehicle body 18 to be painted to the designated position on the equipment via a hoisting structure, providing a reference positioning for subsequent painting operations. The anti-drip overflow base plate 2 installed at the lower end of the vehicle body 18 is composed of four individual connecting matching plates 5 spliced together, and the whole is tilted to the left by five degrees. This tilting design helps the paint dripping during the painting process to collect to the left due to gravity. During the painting operation, the first corrugated telescopic plate 6 fixed to the inner walls of the two sides of the individual connecting matching plate 5 and the two semi-circular inner sliders 7 form an adjustable structure. The semi-circular inner sliders 7 can... The single connecting matching plate 5 slides on the inner walls before and after, while the corresponding semi-circular inner sliders 7 are connected by the second arc-shaped corrugated telescopic plates 8 on the front and rear sides. This allows the centrally located ring block 9 to drive the extension rod nozzle 15, which runs through it, to move in multiple dimensions. The electromechanical arm 14 is installed at the lower end of the extension rod nozzle 15, and its lower end is fixed on the mechanical arm base 13. Through the motion control of the electromechanical arm 14, the extension rod nozzle 15 can be precisely adjusted in position and angle to perform spraying operations on the vehicle chassis. When the paint drips during the spraying process, it is prevented from overflowing due to the anti-drip overflow base plate. The inclined design of plate 2 causes dripping paint to flow to the left, eventually entering the liquid guide vertical pipe 11 through the waste liquid collection holes 10 opened at the inclined positions between the two sets of single connecting matching plates 5 on the left and right sides, and finally flowing into the liquid collection tank 12 to complete the waste liquid collection. This effectively prevents paint dripping from polluting the working environment or causing waste. At the same time, the dust baffles 4 fixed at both ends of the anti-drip overflow base plate 2 are located on the front and rear sides of the vehicle body 18 to be painted, which can block the paint splashing during the spraying process, further improving the cleanliness of the working environment. The purification main pipe 16 fixed at the upper end of the displacement truss 1 passes through the left... The air intake vents 17 on both sides are connected to the external purification system. During the spraying process, the purification system draws harmful gases or atomized particles generated during spraying into the purification main pipe 16 for treatment through the air intake vents 17, ensuring that the air quality of the working environment meets environmental protection requirements. The four individual connecting matching plates 5 are evenly partitioned below the anti-drip overflow base plate 2. This partitioned design not only facilitates targeted operation according to the needs of different spraying areas, but also ensures that when maintenance is required in some areas, it does not affect the normal operation of other areas, improving the flexibility of equipment use and the convenience of maintenance.
[0030] The technical features of the above-described embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0031] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Any appropriate changes and variations made to the above embodiments within the scope of the essential spirit of the present utility model shall fall within the scope of protection claimed by the present utility model.
