Description

Technical Field

[0001] The utility model relates to the technical field of automobile chassis protection, in particular to an automobile chassis anti-rust paint spraying device. Background Art

[0002] Spray painting on the chassis of a car is one of the common methods to prevent the chassis from rusting. The chassis of a car is directly exposed to the outside and is easily eroded by rain, mud, snow melting agents and other substances, which can cause rust. Spray painting can form a protective film on the surface of the chassis to isolate the chassis from corrosion by the external environment and extend the service life of the car. At the same time, spray painting on the chassis can improve the durability of the chassis and make it more able to withstand the impact and wear during driving. During driving, the chassis is easily hit and scratched by objects such as gravel on the road and splashed sand and gravel. The chassis after spraying paint can better resist these damages.

[0003] Based on the above situation, the patent with publication number CN218459901U discloses an automobile chassis spraying equipment, which has four self-locking rollers at the bottom of the bottom plate, two fixed bars fixedly connected to the top of the bottom plate, and a spraying mechanism provided on the top of the bottom plate. The spraying mechanism includes a connecting plate, a mounting bar fixedly connected to the top of the connecting plate, a high-pressure pipeline provided inside the mounting bar, a spray head fixedly installed on the top of the mounting bar, and the spray head is connected to the inside of the high-pressure pipeline. The above-mentioned automobile chassis spraying equipment drives the lead screw to rotate inside the internal threaded connecting sleeve through the operation of the servo motor, and limits the two U-shaped sliders through the fixed bar, so that the connecting block can be driven to move axially on the side surface of the lead screw, and at the same time drives the connecting plate, the mounting bar and the spray head to move together, and the spray head can move at a uniform speed, so that the bottom of the car can be evenly sprayed, thereby improving the painting effect.

[0004] However, the above-mentioned automobile chassis spraying equipment still has some areas for improvement in light of the actual situation. The spraying device of the above-mentioned automobile chassis spraying equipment cannot move laterally, and the dead corners of the automobile chassis are not easily sprayed, resulting in poor spraying effect. At the same time, the above-mentioned automobile chassis spraying equipment only has a spraying device, and lacks consideration of the pre-cleaning step of the automobile chassis before spraying and the drying step after spraying. This may lead to problems such as poor coating effect and unstable coating quality. Utility Model Content

The lateral moving component 6 and the longitudinal moving component 2 cooperate to drive the spray gun 51, so that the spray gun 51 can be moved to different positions under the automobile chassis, which is convenient for the spray gun 51 to evenly spray the automobile chassis. The drying component 7 can quickly dry the anti-rust paint to a suitable temperature and humidity through the cooperation of the air heater 73 and the second air compressor 74, so that the surface of the anti-rust paint coating can be quickly hardened, dust and impurities can be avoided from being contaminated by the coating, and the coating quality can be ensured. The cleaning component 4 can clean the surface of the automobile chassis through the cooperation of the cleaning brush roller 42 and the sponge block 44, thereby providing a good base for the subsequent coating of the anti-rust paint. Make sure the anti-rust paint can evenly adhere to the chassis surface.

[0021] As a preferred embodiment of the present invention, Figure 1As shown, the longitudinal moving assembly 2 includes a support frame 21, a sliding frame 22, a first lead screw 23 and a first motor 25. The support frame 21 is symmetrically arranged at the end positions of both ends of the sliding groove 11 and is connected to the upper surface of the working frame 1. The first lead screw 23 is arranged between the support frames 21. The two ends of the first lead screw 23 are respectively movably connected to the corresponding support frames 21. The first lead screw 23 is provided with a first slidable nut 24. The first nut 24 is arranged inside the sliding frame 22. The left and right sides of the sliding frame 22 are placed in the sliding groove 11. The sliding frame 22 can slide freely in the sliding groove 11.

[0022] The longitudinal moving component 2 is used to drive the lifting component 3 to move longitudinally, so as to adjust the positions of the cleaning component 4, the spraying component 5 and the drying component 7 under the automobile chassis. The first nut 24 is spirally driven through the internal thread and the surface thread of the lead screw. The first lead screw 23 is connected to the support frame 21 at both ends of the working frame 1. The sliding frame 22 is sleeved on the first lead screw 23 through the first nut 24. The left and right ends of the sliding frame 22 are respectively placed in the corresponding sliding grooves 11. The sliding frame 22 performs limited sliding in the sliding groove 11. When the longitudinal moving component 2 is running, the first motor 25 drives the first lead screw 23 to rotate, and the first lead screw 23 and the first nut 24 are threadedly driven, so that the first nut 24 can drive the lifting component 3 to move longitudinally, so as to adjust the positions of the cleaning component 4, the spraying component 5 and the drying component 7 under the automobile chassis.

The lifting electric cylinder 31 is respectively arranged at the four corners of the mounting base plate 32. The telescopic rod end of the lifting electric cylinder 31 is connected to the lower surface of the mounting base plate 32, and the cylinder body end of the lifting electric cylinder 31 is installed on the upper surface of the sliding frame 22. When the lifting assembly 3 increases the position height of the cleaning assembly 4, the spraying assembly 5 and the drying assembly 7, the telescopic rod of the lifting electric cylinder 31 is extended, and the lifting electric cylinder 31 pushes the mounting base plate 32 and the mounting side plate 33 to rise. The cleaning assembly 4, the spraying assembly 5 and the drying assembly 7 are driven by the mounting base plate 32 and the mounting side plate 33 to rise accordingly, so that the cleaning assembly 4, the spraying assembly 5 and the drying assembly 7 are closer to the surface of the automobile chassis, which is convenient for spraying anti-rust paint.

[0025] As another preferred embodiment of the present invention, Figure 2 As shown, the cleaning component 4 includes a second motor 41 and a cleaning brush roller 42, and the cleaning brush roller 42 is horizontally mounted above the mounting base plate 32 through the mounting side plate 33, one end of the cleaning brush roller 42 is connected to the power output shaft of the second motor 41, and the side of the cleaning brush roller 42 close to the spraying component 5 is provided with a fixed side plate 43 connected to the mounting side plate 33 and the mounting base plate 32, and the upper surface of the fixed side plate 43 is connected to a sponge block 44 of the same length as the fixed side plate 43.

[0026] The cleaning component 4 is used to remove dust and impurities from the chassis of the automobile. When the cleaning component 4 is in operation, the sponge block 44 and the cleaning brush roller 42 are tightly attached to the surface of the chassis of the automobile. The second motor 41 drives the cleaning brush roller 42 to rotate, and the brush on the surface of the cleaning brush roller 42 rolls to clean the chassis of the automobile. The sponge block 44 is relatively soft and can fit on the surface of the chassis of the automobile, thereby achieving the purpose of secondary cleaning of the chassis of the automobile.

[0027] As another preferred embodiment of the present invention, Figure 2 As shown, the spray assembly 5 includes a plurality of spray guns 51, a delivery hose 52, a delivery pump 53, a material storage box 54, a first air compressor 55 and a first gas delivery hose 56.

The delivery hose 52 is connected in series with the material storage box 54, the delivery pump 53 and the spray gun 51 in sequence. The first air compressor 55 is connected to the spray gun 51 through the first gas delivery hose 56.

[0028] The lateral movement component 6 includes a sliding block 61, a second screw 62, a second nut 63, and a third motor 64. The second nut 63 is arranged inside the sliding block 61. One end of the second screw 62 is connected to the power output shaft of the third motor 64. The sliding block 61 slides in cooperation with the second screw 62 through the second nut 63.

[0029] The lateral moving component 6 and the spraying component 5 are in a linkage operation state. The spraying component 5 is used to evenly spray the anti-rust paint on the surface of the automobile chassis. The lateral moving component 6 is used to laterally adjust the position of the spraying gun 51 on the surface of the automobile chassis. The spraying guns 51 are equidistantly arranged along the width direction of the working frame 1 to ensure the uniformity and coverage of the spraying. The spraying guns 51 are interconnected through the delivery hose 52. The delivery pump 53 is responsible for delivering the anti-rust paint in the storage box 54 to the spraying gun 51 through the delivery hose 52. The first air compressor 55 is connected to the spraying gun 51 through the first air delivery hose 56 to provide the required air pressure for the spraying gun 51. When the delivery pump 53 starts working, the paint is delivered from the storage box 54 to the spraying gun 51. At the same time, the first air compressor 55 provides air pressure to the spraying gun 51 through the first air delivery hose 56. Under the action of the air pressure, the paint is atomized and sprayed from the nozzle of the spraying gun 51 to form a uniform paint mist.

[0030] The spray gun 51 is vertically installed on the upper surface of the sliding block 61. The transverse moving component 6 can drive the spray gun 51 to reciprocate laterally on the surface of the automobile chassis, so that the anti-rust paint can be evenly sprayed on the surface of the automobile chassis. When the transverse moving component 6 is running, the third motor 64 drives the second screw 62 to rotate. The second nut 63 is arranged inside the sliding block 61 to form a whole with the sliding block 61. The second screw 62 rotates, and there is a threaded fit between the second nut 63 and the second screw 62, which drives the second nut 63 to move on the second screw 62, and the sliding block 61 will also move accordingly, so that the sliding block 61 can drive the spray gun 51 to reciprocate laterally.

[0031] As another preferred embodiment of the present invention, Figure 2 As shown, the drying assembly 7 includes a fixed plate 71, a plurality of jet guns 72, an air heater 73, a second air compressor 74 and a second air hose 75. The fixed plate 71 is horizontally erected between the mounting side plates 33 and connected to the mounting side plates 33. The jet guns 72 are equidistantly arranged on the upper surface of the fixed plate 71. The jet guns 72 are connected to each other through the second air hose 75. The air heater 73 is connected to the second air compressor 74 through the second air hose 75. The second air compressor 74 is connected to the jet gun 72 through the second air hose 75.

[0032] The drying assembly 7 is used to preliminarily dry the chassis of the vehicle after the anti-rust paint is applied, so that the surface of the anti-rust paint can quickly and evenly reach a dry and hardened state, and prevent the anti-rust paint coating on the chassis surface from being contaminated with dust and impurities while waiting for complete drying and hardening, thereby ensuring the integrity and quality of the coating. The jet guns 72 are evenly distributed on the surface of the fixing plate 71, and the jet guns 72 are equidistantly arranged on the surface of the fixing plate 71, so as to evenly dry the surface of the chassis. The air is first heated by the air heater 73, and the heated hot air is then transported to the second air compressor 74 through the second air hose 75. The second air compressor 74 further compresses the hot air and transports it to the jet gun 72 through the second air hose 75, and the jet gun 72 sprays it out, thereby drying the surface of the anti-rust paint.

[0033] It should be noted that the air heater 73 is an existing device, which has a heating wire for heating the air and corresponding components for conveying the air.

[0034] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
