Description

Technical Field

[0001] This utility model relates to the field of fender polishing, and more particularly to a polishing device for fender production. Background Technology

[0002] Fenders are curved covers installed above the wheels on the sides of a car body. They are mainly used to prevent mud, sand, and other debris kicked up by the wheels from splashing onto the car body or outside. They also serve to beautify the car body lines and optimize aerodynamic performance. They are usually made of metal (such as steel plates or aluminum alloys) or composite materials.

[0003] As a crucial body panel for automobiles, the surface finish of the fender directly impacts the overall appearance and corrosion resistance of the vehicle. In current manufacturing processes, fenders require surface polishing after stamping to eliminate minor scratches, burrs, and oxide layers. Polishing is a key step in fender production, improving surface finish and removing burrs and scratches. Existing polishing equipment typically requires workers to manually adjust the polishing wheel, which is time-consuming, labor-intensive, and affects processing efficiency and uniformity due to the reliance on manual wheel positioning.

[0004] Therefore, there is a need for a polishing device for fender production that can reduce manual grinding. Utility Model Content

[0005] In order to overcome the shortcomings of traditional fender polishing which requires manual adjustment of the polishing wheel, the technical problem of this utility model is to provide a polishing device for fender production.

[0006] The technical implementation scheme of this utility model is as follows: A polishing device for fender production includes a frame, a controller, a first drive motor, a first bidirectional screw, a support frame, a second drive motor, a second bidirectional screw, a polishing machine, and a universal grinding head. The controller is installed on the upper part of the frame, and the first drive motor is installed on the right side of the frame. The first drive motor is electrically connected to the controller. A first bidirectional screw is fixedly connected to the output shaft of the first drive motor and is rotatably connected to the frame. A first bidirectional screw is also rotatably connected to the left side of the frame. A support frame is threaded between the two first bidirectional screws. A second drive motor is installed on the left side of the support frame and is electrically connected to the controller. A second bidirectional screw is fixedly connected to the output shaft of the second drive motor and is rotatably connected to the right side of the support frame. A polishing machine is slidably connected to the support frame and is electrically connected to the controller. The polishing machine is also threadedly connected to the second bidirectional screw. A universal grinding head is also installed at the bottom of the polishing machine.

[0007] More preferably, it also includes a stage, vacuum suction cups and an air pump. The stage is slidably connected to the top of the frame, and several vacuum suction cups are provided on the stage. An air pump is installed in the middle of the frame. The air pump is electrically connected to the controller, and the air pump is connected to the vacuum suction cups through an air pipe.

[0008] More preferably, the stage is inlaid with a magnet that can attract waste iron or steel shavings generated during the polishing process.

[0009] More preferably, each vacuum suction cup is interconnected by an air tube.

[0010] More preferably, it also includes a rotating rod, bevel gears, lead screws, and support blocks. The rotating rod is rotatably connected to the bottom of the frame, and bevel gears are symmetrically fixed to both sides of the rotating rod. Lead screws are symmetrically rotatably connected to the middle of the frame, and bevel gears are fixed to the bottom of each lead screw. Two bevel gears located on the same side of the frame mesh with each other. Support blocks are threaded onto both lead screws, and the two support blocks are slidably connected to the platform.

[0011] More preferably, the lever is equipped with a handle that is easy to rotate.

[0012] Compared with existing technologies, this utility model has the following advantages: 1. This utility model uses a first drive motor and a second drive motor to drive the first bidirectional screw and the second bidirectional screw to rotate respectively, which can precisely control the movement of the support frame and the servo motor, thereby achieving precise positioning and movement of the polishing machine on the fender. This design effectively improves the accuracy of polishing, avoids positional deviations that may be caused by manual operation, and thus improves the polishing quality. At the same time, this control method reduces the human input in adjusting the polishing position, improves overall work efficiency, and reduces labor costs.

[0013] 2. This invention uses an air pump to extract air from the vacuum suction cup, thereby firmly adhering the car fender to the platform. This fixing method can adapt to fenders of different sizes and shapes, ensuring that the fender will not shift during the grinding process, guaranteeing grinding precision, and helping to improve product quality.

[0014] 3. This utility model uses a rotating rod to drive a bevel gear to rotate, which in turn rotates the lead screw and moves the support block and the platform. This allows the platform to be easily moved to a suitable position for subsequent operations. This not only facilitates the recovery of iron filings and other debris on the platform but also makes it easier to replace the vacuum suction cup, thus making the maintenance of the device more convenient.

Detailed Implementation

[0021] First, it should be noted that in different described embodiments, the same components are given the same reference numerals or the same component names. The disclosure contained throughout this specification can be applied semantically to the same components having the same reference numerals or the same component names. The location descriptions selected in the specification, such as upper, lower, lateral, etc., also refer to the directly described and illustrated figures and are semantically applied to the new location when the location changes.

[0022] Example: A polishing apparatus for fender production, such as Figures 1-5 As shown, the assembly includes a frame 1, a controller 101, a first drive motor 2, a first bidirectional screw 3, a support frame 4, a second drive motor 5, a second bidirectional screw 6, a polishing machine 7, and a universal polishing head 8. The controller 101 is bolted to the upper front of the frame 1. The first drive motor 2 is bolted to the right side of the frame 1. The first drive motor 2 is electrically connected to the controller 101. A first bidirectional screw 3 is fixed to the output shaft of the first drive motor 2, which is rotatably connected to the frame 1. A second bidirectional screw 6 is also rotatably connected to the left side of the frame 1. A bidirectional screw 3 is provided, and a support frame 4 is threadedly connected between the two bidirectional screws 3. A second drive motor 5 is bolted to the left side of the support frame 4. The second drive motor 5 is electrically connected to the controller 101, and a second bidirectional screw 6 is fixedly connected to the output shaft of the second drive motor 5. The second bidirectional screw 6 is rotatably connected to the right side of the support frame 4. A polishing machine 7 is slidably connected to the support frame 4. The polishing machine 7 is electrically connected to the controller 101, and the polishing machine 7 is threadedly connected to the second bidirectional screw 6. A universal grinding head 8 is also installed at the bottom of the polishing machine 7.

[0023] When using this device, it should first be placed stably on a flat surface to ensure that it will not tilt or move due to uneven ground. The user needs to place the car fender on the vacuum suction cup 10 on the platform 9, and then start the air pump 11 through the controller 101. The air pump 11 extracts the air from the vacuum suction cup 10 through the air tube, thereby adsorbing the fender onto the platform 9, completing the fixation of the fender and preventing it from moving during grinding and polishing. This fixing method can accommodate fenders of different sizes and shapes.

[0024] like Figure 1 and Figure 3 As shown, it also includes a stage 9, a vacuum suction cup 10, and an air pump 11. The stage 9 is slidably connected to the top of the frame 1, and a magnet is embedded inside the stage 9. The magnet can attract the waste iron or steel chips generated during the polishing process. Several vacuum suction cups 10 are also provided on the stage 9, and each vacuum suction cup 10 is connected to each other through an air pipe. The air pump 11 is bolted to the right side of the middle of the frame 1. The air pump 11 is electrically connected to the controller 101, and the air pump 11 is connected to the vacuum suction cup 10 through an air pipe.

[0025] Next, the controller 101 starts the first drive motor 2, whose output shaft drives the first bidirectional screw 3 to rotate, thereby driving the support frame 4 to move back and forth on the two first bidirectional screws 3. Then, the controller 101 starts the second drive motor 5, which drives the servo motor to move left and right on the second bidirectional screw 6, thus moving the polishing machine 7 left and right on the fender. When the universal polishing head 8 is in contact with the fender, it automatically adjusts the polishing direction. This polishing method reduces manpower and improves work efficiency. The waste generated during polishing is attracted by magnets embedded in the stage 9, which helps improve resource utilization and reduce pollution.

[0026] like Figure 4 Figure 5 As shown, it also includes a rotating rod 12, a bevel gear 13, a lead screw 14, and a support block 15. The rotating rod 12 is rotatably connected to the bottom of the frame 1, and a handle for easy rotation is installed on the rotating rod 12. The bevel gears 13 are symmetrically fixed to the left and right sides of the rotating rod 12. The lead screw 14 is symmetrically rotatably connected to the middle of the frame 1. The bottom of each lead screw 14 is fixedly connected to a bevel gear 13. Two bevel gears 13 located on the same side of the frame 1 mesh with each other. Support blocks 15 are threadedly connected to both lead screws 14. The two support blocks 15 are slidably connected to the platform 9.

[0027] After the device is used, the polishing machine 7, the first drive motor 2, the second drive motor 5, and the air pump 11 can be stopped sequentially by the controller 101. The polished fender can then be removed from the vacuum suction cup 10, which no longer uses air pressure to hold the fender. Then, the handle is turned, causing the two bevel gears 13 on the rotating rod 12 to rotate. This causes the bevel gear 13 on the lead screw 14 to rotate, which in turn rotates the lead screw 14. This causes the support block 15 to move along with the platform 9 on the lead screw 14. When the platform 9 moves to the center of the frame 1, it can be slid off the support block 15, allowing for the collection of iron filings and other debris from the platform 9. Simultaneously, the vacuum suction cup 10 can be replaced. This design makes the maintenance and operation of the device more convenient and efficient.

[0028] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art that various changes or modifications can be made to the present invention without departing from the principles and spirit of the present invention as defined by the claims. Therefore, the detailed description of the embodiments in this disclosure is for explanation only and not for limiting the present invention, but rather the scope of protection is defined by the content of the claims.
