Description

Technical Field

[0001] This utility model relates to the technical field of automotive parts processing equipment, specifically a fuel tank shell grinding and polishing device. Background Technology

[0002] As a core component of gasoline-powered vehicles for storing fuel, the fuel tank requires high strength and corrosion resistance. Therefore, manufacturers typically apply a protective coating to the fuel tank during manufacturing to enhance its protection. To ensure the adhesion of this protective coating, the fuel tank needs to be polished before application. Additionally, after welding, the fuel tank also requires polishing to improve its overall aesthetics and smoothness. Currently, due to the limited polishing area of ​​a single polishing assembly, multiple polishing assemblies are usually used simultaneously. However, these multiple assemblies are typically located on the same plane, limiting their application to a single side of the fuel tank and resulting in lower efficiency. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a fuel tank shell grinding and polishing device. It is equipped with multiple polishing components, and the angle of the polishing components can be adjusted according to the grinding requirements of the fuel tank. It can be used not only for grinding and polishing the outside of the fuel tank, but also for grinding and polishing the inside of the fuel tank. It has high working efficiency and grinding quality. At the same time, it has a certain buffering effect during use, reducing the damage caused by the collision between the polishing components and the fuel tank. It can effectively solve the problems in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a fuel tank shell grinding and polishing device, including a guide rail, a connecting frame slidably mounted on the guide rail, a driving component provided on the side of the connecting frame, an mounting plate provided below the connecting frame, a lifting component provided between the mounting plate and the connecting frame, an adjusting plate rotatably mounted on both sides of the mounting plate, an adjusting component for driving the adjusting plate to rotate provided on the side of the mounting plate, and a polishing component mounted on both the mounting plate and the adjusting plate.

[0005] As a preferred embodiment of the present invention, the polishing assembly includes a first motor, and a polishing wheel is mounted on the drive shaft of the first motor.

[0006] As a preferred embodiment of this utility model, a protective shell for protecting the first motor is installed on the side of the adjustment plate, a positioning frame is fixed on the upper side of the mounting plate, and the adjustment assembly includes a servo electric cylinder. The fixed end of the servo electric cylinder is rotatably connected to the positioning frame, and the telescopic end of the servo electric cylinder is rotatably connected to the protective shell.

[0007] As a preferred embodiment of this utility model, the connecting frame has positioning plates fixed on both sides of the guide rail, and a drive wheel on the guide rail is rotatably mounted on the side of the positioning plate. The drive assembly includes a second motor, which is mounted on the side of one of the positioning plates and used to control the rotation of the drive wheel on the positioning plate.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. The fuel tank shell polishing device of this utility model, when polishing the fuel tank through the polishing components, controls the first motor to drive the polishing wheel to rotate, and the polishing wheel polishes the fuel tank shell. The multiple polishing components can increase the polishing area, thereby improving the polishing efficiency of the fuel tank shell. Each polishing component is driven independently. During the polishing process, the power of the first motor at a certain position can be adjusted according to the flatness of the fuel tank shell surface. Alternatively, only one set of polishing components can be controlled to work to polish the fuel tank shell as needed.

[0012] 2. The fuel tank shell grinding and polishing device of this utility model allows for adjustment of the angle of the adjustment plate during the polishing process. When polishing the exterior of the fuel tank shell, the servo electric cylinder is extended and driven to rotate, causing the polishing components on the side of the adjustment plate to move to other surfaces on the outside of the fuel tank. At this time, the polishing device is clamped and covered on the outside of the fuel tank, and can be used for simultaneous polishing of multiple surfaces on the outside of the fuel tank.

[0013] 3. The fuel tank housing polishing device of this utility model uses a second motor to drive the drive wheel to rotate, causing the connecting frame to slide along the guide rail, which facilitates the adjustment of the position of the polishing component. It can be used for overall polishing of the fuel tank housing. The hydraulic telescopic cylinder facilitates the adjustment of the height position of the polishing component. At the same time, the hydraulic telescopic cylinder facilitates the contact or separation of the polishing component from the fuel tank housing, which facilitates the use of the polishing component.

[0014] 4. In the fuel tank shell grinding and polishing device of this utility model, when the hydraulic telescopic cylinder drives the mounting plate to move down and contact the fuel tank shell, the spring set on the outside of the positioning rod plays a buffering role, which alleviates the collision caused by the excessive downward movement of the mounting plate driven by the hydraulic telescopic cylinder, and reduces the economic losses caused by the collision between the polishing components and the fuel tank.

[0022] The polishing assembly includes a first motor 5, and a polishing wheel 6 is mounted on the drive shaft of the first motor 5. When polishing the fuel tank, the first motor 5 is controlled to drive the polishing wheel 6 to rotate, and the polishing wheel 6 polishes the fuel tank shell. The multiple polishing assemblies can increase the polishing area, thereby improving the polishing efficiency of the fuel tank shell. Each polishing assembly is driven independently. During the polishing process, the power of the first motor 5 at a certain position can be adjusted according to the flatness of the fuel tank shell surface. Alternatively, only one set of polishing assemblies can be controlled to polish the fuel tank shell as needed. The polishing wheel 6 is replaceable. This polishing device is equipped with different specifications according to the fuel tank model. The polishing assembly on the mounting plate 3 can cover at least one entire surface of the fuel tank shell, and the polishing assembly on the side of the adjusting plate 4 can cover at least half of the fuel tank shell.

[0023] A protective shell 8 for protecting the first motor 5 is installed on the side of the adjusting plate 4. A positioning frame 7 is fixed on the upper side of the mounting plate 3.

During the polishing process, the angle of the adjusting plate 4 can be adjusted as needed. When polishing the outside of the fuel tank housing, the servo electric cylinder 9 is extended, and the servo electric cylinder 9 drives the adjusting plate 4 to rotate, so that the polishing assembly on the side of the adjusting plate 4 moves to other surfaces outside the fuel tank. At this time, the polishing device is clamped and covered on the outside of the fuel tank, which can be used for simultaneous polishing of multiple surfaces outside the fuel tank. When polishing the inside of the fuel tank housing, the servo electric cylinder 9 is shortened, and the servo electric cylinder 9 drives the adjusting plate 4 to rotate, so that the polishing assembly on the side of the adjusting plate 4 moves to the inside of the fuel tank, which can be used for simultaneous polishing of multiple surfaces inside the fuel tank housing, improving polishing efficiency.

[0025] The lifting assembly includes a hydraulic telescopic cylinder 13. The fixed end of the hydraulic telescopic cylinder 13 is connected and fixed to the connecting frame 2. A buffer assembly is provided at the telescopic end of the hydraulic telescopic cylinder 13, and the buffer assembly is installed on the mounting plate 3.
