[0003] Traditional spraying equipment has uneven coating due to uneven airflow or improper operation, and there are cases of missed spraying or uneven density. There is material waste in the spraying process, such as overspraying, material drifting and splashing during spraying, etc. Manual operation is often required to complete the cleaning, positioning and spraying of parts, which is not only inefficient, but may also cause uneven coating due to improper operation. The cleaning and pretreatment of the part surface are often not thorough enough, which will affect the adhesion and quality of the coating. Manual operation is usually required, and there are problems such as inconsistent operating skills and high labor intensity.

[0024] Please refer to the attached Figure 1 -Attached Figure 8The centering and gathering mechanism 5 is located between the positioning drive mechanism 3 and the extension frame 2, and is used for the motion output of the spraying and smearing mechanism 8. The centering and gathering mechanism 5 includes two sets of side push components and a fixed platform 53, a rotating shaft column 55 and a center linkage plate 56. The side push components are distributed on both sides of the top of the base 1. The side push components are linked and transmitted through the fixed platform 53, the rotating shaft column 55 and the center linkage plate 56. The fixed platform 53 is fixedly connected to the center of the top of the base 1, the rotating shaft column 55 is rotatably connected to the top of the fixed platform 53, and the center linkage plate 56 is fixedly connected to the output shaft at the top of the rotating shaft column 55. The side push components include a hydraulic pusher 51, a transverse guide rail 52, a centering pusher 54, a double-end rotating rod 57, a linkage slide 58 and a zigzag fixed frame 59. The hydraulic pusher Component 51 is fixedly connected to the top of the base 1, the transverse guide rail 52 is fixedly connected to the top of the base 1 and is located between the hydraulic push components 51, the double-end rotating rod 57 is rotatably connected to the two ends of the central linkage plate 56, the linkage slide 58 is slidably connected to the transverse guide rail 52, the zigzag fixed frame 59 is fixedly connected to the top of the linkage slide 58, and the other side ends of the double-end rotating rod 57 are respectively rotatably connected to the top of the linkage slide 58, the upper part of the inner wall of the zigzag fixed frame 59 is fixedly connected to the push rod 510, the centering push platform 54 is fixedly connected to the inner end of the push rod 510 and is located above the positioning drive mechanism 3, when the pneumatic cleaning mechanism 7 is started, the centering gathering mechanism 5 is synchronously opened, and the centering gathering mechanism 5 itself includes two sets of side push components arranged oppositely on the top of the base 1, At the same time, the fixed platform 53, the rotating shaft column 55 and the central linkage plate 56 included in the centering and gathering mechanism 5 can make the two sets of side push assemblies run synchronously, and start the hydraulic pushers 51 included in each of the side push assemblies. When the hydraulic pushers 51 are started and push a set of zigzag fixed frames 59 fixed at the conveying ends of the two to move to the right, the zigzag fixed frames 59 use the linkage slides 58 installed at the bottom to slide to the right on the two sets of transverse guide rails 52 installed on the top right side of the base 1. When the zigzag fixed frames 59 move to the right, the zigzag fixed frames 59 drive the corresponding double-end rotating rods 57 installed in the middle to rotate outward and unfold. After the movement of the double-end rotating rods 57, the fixed platform 53 installed at the other end is driven to start to rotate along the rotating shaft column 55 rotates, and the rotation of the center linkage plate 56 drives another group of double-end rotating rods 57 installed at the other end to rotate. The rotation of the double-end rotating rods 57 is simultaneously extended outward, and the double-end rotating rods 57 drive another group of zigzag fixed frames 59 to move outward along the linkage slide 58 installed at the bottom on the transverse guide rail 52 on the top side of the base 1, so that the two groups of zigzag fixed frames 59 can move in relative directions at the same time. The centering push platform 54 installed on the top of the two groups of zigzag fixed frames 59 through the push rod 510 is used to clamp the shaft parts transported on the positioning drive mechanism 3 from the left and right sides, and correct the position of the shaft parts from both sides. The side push assemblies are each equipped with a group of spraying and smearing mechanisms 8 arranged opposite to each other through the centering push platform 54.The spraying and smearing mechanism 8 is simultaneously located on the surface of the positioning drive mechanism 3 in the conveying direction of the axial parts, when the centering pusher 54 is synchronously approached.

[0025] Please refer to the attached Figure 1 -Attached Fig.11 The pneumatic cleaning mechanism 7 cooperates with the positioning driving mechanism 3 to blow and clean the mechanical parts. At the same time, the material storage pool 81, the air inlet cylinder 76 and the driving turbofan 78 are used to drive the spraying and smoothing mechanism 8 to operate. The pneumatic cleaning mechanism 7 includes a main air pipe 71 and a pressurized air pipe 73. The main air pipe 71 is fixedly connected to the bottom wall of the fixed stand 4. The side wall of the main air pipe 71 is provided with evenly distributed output ports. The input port of the main air pipe 71 is fixedly connected to an air pump 72. The air pump 72 is fixedly connected to the side wall of the fixed stand 4. The compressed air pipe 73 is evenly distributed and fixedly connected to the bottom wall of the fixed stand 4. The output port of the main air pipe 71 is connected to the input port of the pressurized air pipe 73. The end of the main air pipe 71 away from the air pump 72 is fixedly connected to a three-way pipe 74. The three-way pipe 74 has two output ports and is fixedly connected to a gas hose 75. The output end of the gas hose 75 away from the three-way pipe 74 is fixedly connected to an air inlet cylinder 76. The air inlet cylinder 76 is fixedly connected to the side wall of the storage tank 81. The top wall of the air inlet cylinder 76 is fixedly connected to an exhaust pipe 77. The inner wall of the air cylinder 76 is rotatably connected to a driving turbofan 78, which is fixedly connected to the outer rotating shaft of the wiping roller 82. The shaft part first enters the interior of the fixed stand 4, and the centering and focusing mechanism 5 and the pneumatic cleaning mechanism 7 are turned on at the same time. The air pump 72 included in the pneumatic cleaning mechanism 7 generates high-pressure wind and delivers it to the main air pipe 71, which is distributed and delivered to the pressurized air pipe 73 arranged side by side inside the fixed stand 4, and the pressurized air pipe 73 blows the high-pressure wind to the positioning drive mechanism 3. The conveyed axial parts are cleaned of dust before spraying, and the high-pressure wind generated by the air pump 72 is continuously transported to the three-way pipe 74 along the main air pipe 71 and is transmitted to the air hose 75 by the three-way pipe 74, and is transmitted to the corresponding air intake cylinder 76 by the two groups of air hoses 75. Since the high-pressure wind force is directly blown into the air intake cylinder 76, the driving turbofan 78 installed inside the air intake cylinder 76 starts to rotate synchronously due to the impact of the high-pressure wind, and the high-pressure wind passes through the driving turbofan 78 and is discharged from the exhaust pipe 77 arranged on the top wall of the air intake cylinder 76.

[0026] Please refer to the attached Figure 1 -Attached Fig.11The spraying and smearing mechanism 8 is used for gathering and wiping mechanical parts through the cooperation of the wiping roller 82 and the centering push platform 54. The spraying and smearing mechanism 8 includes a storage pool 81, which is fixedly connected to the top wall of the centering push platform 54 and is adjacent to the fixed stand 4. The bottom wall of the storage pool 81 is provided with evenly distributed nozzles. The bottom wall of the storage pool 81 is rotatably connected with a wiping roller 82. The outer side of the bottom wall of the storage pool 81 is fixedly connected with a gathering ramp 83, and the gathering ramp 83 is rotatably connected with evenly distributed gathering wheels 84. The rotating shaft of the wiping roller 82 passes through the side wall of the storage pool 81. The storage pools 81 included in the spraying and smearing mechanism 8 are also close to each other. The bottom of the storage pool 81 is provided with The gathering ramp 83 also synchronously approaches along the surface of the guide roller frame 31 and shovels the axial parts against each other. The nozzles arranged on the bottom wall of the storage pool 81 begin to spray anti-rust paint on the surface of the axial parts. Because the driving turbofan 78 driven by the high-pressure wind also links the wiping roller 82 arranged inside the storage pool 81 to start rotating, a part of the wiping roller 82 is located inside the storage pool 81, and the anti-rust paint temporarily stored in the storage pool 81 can be wiped to the surface of the axial parts. While in contact and rotating, the axial parts will also be driven to start rotating along the gathering wheel 84 installed on the gathering ramp 83, and then the entire side is sprayed, and the anti-rust paint on the surface of the parts can also be wiped and evenly spread.

[0027] Working principle: The axial parts waiting for anti-rust paint coating are first transported through the positioning drive mechanism 3 fixed by the extension frame 2 on the top of the base 1, and the guide roller frame 31 included in the positioning drive mechanism 3 is transported through its own distribution guide rollers, and the distribution guide rollers are linked to rotate by the butt-jointed belt transmission parts 32, and the output motor 33 is used to output the rotational torque to make the entire guide roller mechanism of the guide roller frame 31 run and transport the axial parts. The axial parts first enter the interior of the fixed stand 4, and at the same time, the centering and gathering mechanism 5 and the pneumatic cleaning mechanism 7 are turned on. The air pump 72 included in the pneumatic cleaning mechanism 7 generates high-pressure wind and transports it to the main air pipe 71, which is then distributed and transported to the pressurized air ducts arranged side by side inside the fixed stand 4. 73, and the pressurized air duct 73 blows the high-pressure wind to the axial parts transported by the positioning drive mechanism 3 to clean the dust before spraying. The high-pressure wind generated by the air pump 72 is continuously transported to the three-way pipe 74 along the main air pipe 71 and is transmitted to the air delivery hose 75 by the three-way pipe 74, and is transmitted to the corresponding air intake cylinder 76 by the two sets of air delivery hoses 75. Since the high-pressure wind is directly blown into the air intake cylinder 76, the driving turbofan 78 installed inside the air intake cylinder 76 starts to rotate synchronously under the impact of the high-pressure wind. After passing through the driving turbofan 78, the high-pressure wind is discharged from the exhaust pipe 77 set on the top wall of the air intake cylinder 76. When the pneumatic cleaning mechanism 7 is started, the centering and focusing mechanism 5 is synchronously opened. The centering and focusing mechanism 5 itself includes two sets of side thrust assemblies arranged opposite to each other on the base 1. At the top, the fixed platform 53, the rotating shaft column 55 and the central linkage plate 56 included in the centering and gathering mechanism 5 can make the two sets of side push assemblies run synchronously, and start the hydraulic pushers 51 included in each of the side push assemblies. When the hydraulic pushers 51 are started and push a set of zigzag fixed frames 59 fixed at the conveying ends of the two sides to move to the right, the zigzag fixed frames 59 use the linkage slides 58 installed at the bottom to slide to the right on the two sets of transverse guide rails 52 installed on the top right side of the base 1. When the zigzag fixed frames 59 move to the right, the zigzag fixed frames 59 drive the corresponding double-end rotating rods 57 installed in the middle to rotate outward and unfold. After the movement of the double-end rotating rods 57, the fixed platform 53 installed at the other end is driven to start to rotate along the rotating axis. The column 55 rotates, and the rotation of the center linkage plate 56 drives another group of double-end rotating rods 57 installed at the other end to rotate. The rotation of the double-end rotating rods 57 is simultaneously expanded outward, and the double-end rotating rods 57 drive another group of zigzag fixed frames 59 to move outward along the linkage slide 58 installed at the bottom on the transverse guide rail 52 on the top side of the base 1, so that the two groups of zigzag fixed frames 59 can move in relative directions at the same time. The centering push platform 54 installed on the top of the two groups of zigzag fixed frames 59 through the push rod 510 is used to clamp the axial parts transported on the positioning drive mechanism 3 from the left and right sides, and correct the position of the axial parts from both sides. The side push assemblies are each equipped with a group of spraying and smearing mechanisms 8 set opposite to each other through the centering push platform 54.The spraying and smearing mechanism 8 is also located at the position of the conveying direction of the axial parts on the surface of the positioning drive mechanism 3. When the centering push platform 54 is synchronously moved together, the storage pools 81 included in the spraying and smearing mechanism 8 are also moved together. The gathering ramp 83 set at the bottom of the storage pool 81 is also synchronously moved together along the surface of the guide roller frame 31 and shovels the axial parts together. The nozzle set at the bottom wall of the storage pool 81 starts to spray anti-rust paint on the surface of the axial parts. Because the driving turbofan 78 driven by high-pressure wind is also linked to the storage pool 8 at the same time, The wiping roller 82 disposed inside the 1 starts to rotate, and a part of the wiping roller 82 is located inside the storage tank 81, so that the anti-rust paint temporarily stored inside the storage tank 81 can be wiped and applied to the surface of the shaft-shaped parts. While contacting and rotating, the shaft-shaped parts will also be driven to start rotating along the gathering wheel 84 installed on the gathering ramp 83, and then the entire side surface will be sprayed, and the anti-rust paint on the surface of the parts can also be wiped and evenly applied. The anti-rust paint leaked through the guide roller frame 31 falls onto the recovery ramp 6, and is guided back to the recovery ramp 6. The whole structure utilizes the high pressure cleaning wind generated by the pneumatic cleaning mechanism 7 to drive the driving turbofan 78 to rotate, so that the driving turbofan 78 drives the wiping roller 82 in contact with the surface of the parts to rotate, so that the anti-rust paint and the anti-rust liquid can be fully covered. The axial parts that have been coated are continuously transported by the guide roller frame 31, and gradually pass through the gantry notch of the suspension frame 36 included in the positioning drive mechanism 3, and the main shaft is fixed again by the centering and gathering mechanism 5 and the spraying and smearing mechanism 8, and the suspension frame 36 is a group of gantry suspensions. The two ends of the suspension frame 36 are restricted in the side frames 34 installed on both sides of the top of the guide roller frame 31 by the added nut auxiliary structure, and the fixed screw 35 installed in the side frames 34 controls the displacement of the suspension frame 36, so that the suspension frame 36 can carry the hydraulic output component 37 installed on it and the extension seat 38 and positioning probe 39 installed on the output end of the hydraulic output component 37 to move above the main shaft until it reaches the coating position, and at the same time, the hydraulic output component 37 is turned on to make the extension seat 38 descend, so as to quickly drill and fix the main shaft.
