Description

Technical Field

[0001] This utility model belongs to the field of automotive sheet metal polishing technology, and in particular relates to an automotive sheet metal surface polishing device. Background Technology

[0002] Currently, automobiles provide immense convenience for human travel, and as people's demands for automobiles increase, the automobile itself has undergone significant development. The components that make up a car body can be broadly categorized into panel components, structural components, running gear components, and reinforcing components. These components correspond to different application requirements and have different performance characteristics. For example, panel components require sheet metal with good formability, strength, elongation, dent resistance, and corrosion resistance. Automotive sheet metal is the main material constituting automotive panels and has high requirements for surface quality, necessitating surface polishing to meet specific requirements.

[0003] Currently, when sanding automotive body panels, workers need to fix the panels in place and sand them manually. After sanding, the panels are removed and replaced with another panel for sanding. This method greatly increases the labor intensity of workers, is inefficient, and has poor practicality.

Through the cooperation between the guide rail 2 and the chain 4, the limiting seats 13 can continuously move in a cyclical manner along the path direction of the guide rail 2. The bottom of the support platform 1 is equipped with a drive mechanism for driving the sprocket 3 to rotate. The drive mechanism includes a second motor 16, and a reducer 17 is connected to the shaft of the second motor 16. The output shaft of the reducer 17 is connected to the rotation shaft of one of the sprockets 3. By starting the second motor 16, the sprocket 3 can be rotated, thereby causing the sprocket 3 to drive the chain 4 to move, which in turn causes the chain 4 to drive the limiting seat 13 to move along the path of the guide rail 2. The middle part of one side of the limiting seat 13 is fixedly connected to the chain 4 through a connecting block 14. Rollers 18 that are rolled and connected to the guide rail 2 are provided on both sides of the bottom of the limiting seat 13. By setting the limiting seat 13 to be fixedly connected to the chain 4 through the connecting block 14, the chain 4 can drive the limiting seat 13 to move during the movement, and the movement of the limiting seat 13 is more stable and reliable under the action of the rollers 18. The upper surface of the limiting seat 13 is provided with a limiting groove 15 for placing the car body panel, and the four sides of the limiting groove 15 are provided with notches. The limiting groove 15 is used to limit and fix the car body panel, and the notches facilitate quick loading and unloading of the car body panel.

[0024] A vertical plate 5 is provided in the middle of the upper surface of the support platform 1. An L-shaped seat 8 that can move up and down is provided on the side wall of the vertical plate 5. An electric push rod 6 is installed on the top of the vertical plate 5 through a mounting bracket. The bottom of the piston rod of the electric push rod 6 is fixedly connected to the top of the L-shaped seat 8. Two vertically distributed slide rails 7 are provided on the side wall of the vertical plate 5. A slider that slides up and down with the slide rails 7 is provided on the back of the L-shaped seat 8.

Under the action of the slider and the slide rails 7, the L-shaped seat 8 is limited, making the L-shaped seat 8 more stable and reliable when moving up and down. A first motor 10 is provided on the upper surface of the horizontal part of the L-shaped seat 8. The shaft of the first motor 10 is connected to a second grinding pulley 11. The vertical part of the L-shaped seat 8 is rotatably connected to a first grinding pulley 9 above the second grinding pulley 11. A connecting plate 19 is provided on the vertical part of the L-shaped seat 8. Two opposing adjusting plates 20 are provided on the side wall of the connecting plate 19. A connecting shaft 21 is slidably connected between the two adjusting plates 20. A tensioning wheel 22 is rotatably connected to the middle part of the connecting shaft 21 through a bearing. A grinding belt 12 is provided between the tensioning wheel 22, the first grinding pulley 9, and the second grinding pulley 11. The bottom of the grinding belt 12 is correspondingly distributed with the limiting seat 13 located on the front guide rail 2.

The adjustment plate 20 is located between the stop block 24 and the knob. The adjustment hole 23 is horizontally set. By loosening the knob, the tension wheel 22 can be moved along the length of the adjustment plate 20, thereby adjusting the tension of the grinding belt 12. After adjustment, the knob can be tightened, which facilitates the replacement and maintenance of the grinding belt 12. The operation is simple and convenient.

[0025] The working principle of this automotive sheet metal surface sanding device is as follows: During use, a designated location is used as the loading station. A worker is assigned to this station to handle loading and unloading. The worker places the automotive sheet metal to be sanded into the limiting groove 15 on the limiting seat 13. By starting the second motor 16, the limiting seat 13 moves slowly along with the chain 4. When it moves below the sanding belt 12, the electric push rod 6 is activated, causing the L-shaped seat 8 to move downwards, thus bringing the sanding belt 12 into contact with the surface of the automotive sheet metal. Simultaneously, the first motor 10 is activated, causing the second sanding pulley... 11. The first grinding pulley 9 and the tensioning pulley 22 drive the grinding belt 12 to move, thereby grinding the surface of the automotive sheet during the movement. When the automotive sheet on the limit seat 13 is finished being ground, the next limit seat 13 will move to the bottom of the grinding belt 12 to continue grinding the automotive sheet, thus achieving uninterrupted grinding of the automotive sheet, which greatly improves the grinding efficiency and has a high degree of automation. Only one worker is needed to pick up and put down the sheet, which greatly saves manpower, reduces the labor intensity of workers, and is highly practical.
