Description

Technical Field

[0001] The invention relates to the technical field of wheel hub processing, and in particular to an automobile aluminum alloy wheel hub polishing device. Background Art

[0002] Grinding is a kind of surface modification technology. It generally refers to a processing method that uses rough objects to change the physical properties of the material surface through friction. The main purpose is to obtain a specific surface roughness. There are three methods of grinding: dry grinding, wet grinding and mechanical grinding: ① Dry grinding: grinding with sandpaper, suitable for grinding hard and brittle paints. Its disadvantage is that a lot of dust will be generated during the operation, affecting environmental hygiene; ② Wet grinding: grinding with water sandpaper dipped in water or soapy water. Water grinding can reduce wear marks, improve the smoothness of the coating, and save sandpaper and labor. However, after water grinding, attention should be paid to spraying the lower layer of paint. First, the water-grinded layer must be completely dry before the lower layer of paint can be applied, otherwise the paint layer will easily turn white. In addition, the substrate with strong water absorption is not suitable for water grinding; ③ Mechanical grinding: When constructing a large area, in order to improve work efficiency, mechanical grinding methods such as electric grinders can be used.

[0030] It should also be understood that the terms used in this description of the embodiments of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the embodiments of the present invention. As used in the description of the embodiments of the present invention and the appended claims, unless the context clearly indicates otherwise, the singular forms of "a", "an" and "the" are intended to include plural forms.

[0031] As shown in the accompanying drawings, a specific embodiment of the present invention is a vehicle aluminum alloy wheel hub polishing device, comprising a frame 10, a lifting assembly, a fixing assembly, a driving assembly and a polishing liquid storage barrel 1;

[0032] The lifting assembly and the polishing liquid storage bucket are arranged on a frame, the driving assembly is installed on the lifting assembly, the fixing assembly is transmission-connected with the driving assembly, the driving assembly is used to drive the driving assembly to rotate, the fixing assembly is used to fix the aluminum alloy wheel hub to be polished, and the lifting assembly is used to drive the aluminum alloy wheel hub to enter or leave the polishing liquid storage bucket.

[0033] In the above scheme, the aluminum alloy wheel hub is sent into the polishing liquid storage barrel through the lifting component, and then the aluminum alloy wheel hub is driven by the driving component to rotate and contact with the polishing liquid in the polishing liquid storage barrel. The polishing liquid is used for grinding, which can effectively improve the polishing accuracy.

[0034] As another embodiment of the present invention, the lifting assembly includes a lifting plate 4, a screw rod 11, a rotating handle 9 and a guide rod 8, wherein the guide rod 8 is vertically mounted on the frame 10, the screw rod 11 is rotatably mounted on the frame 10, the lifting plate 4 is provided with a threaded hole matched with the screw rod 11 and a guide hole matched with the guide rod 8, and the rotating handle 9 is arranged at the upper end of the screw rod 11. The screw rod is rotated by rotating the rotating handle, thereby driving the lifting plate to move up and down along the guide rod.

[0035] As another embodiment of the present invention, the driving assembly includes a driving motor 5 and a driving shaft 7, the driving motor 5 is installed on the lifting plate 4, the driving shaft 7 is transmission-connected to the output end of the driving motor 5, and the fixing assembly is arranged on the driving shaft 7.

[0036] Among them, the fixing assembly includes a fixing plate 21 and a plurality of bolts 19, the fixing plate 21 is provided with a plurality of fixing holes, the wheel hub 14 is provided with a spoke 15, and the spoke 15 is provided with a plurality of threaded holes at positions corresponding to the fixing holes, the bolts 19 pass through the fixing holes and are connected with the threaded holes, and the fixing plate is fixedly connected to the lower end of the drive shaft.

[0037] It should be noted that, since the polishing liquid has a polishing effect, that is, the polishing liquid has a certain grinding effect, during the polishing process of the wheel hub, the fixing component is constantly in contact with the polishing liquid, and the polishing liquid will grind the connection between the head of the bolt and the fixing plate 21 and the drive shaft 7, causing the bolt head to become smooth. When the head of the bolt becomes smooth, it will cause the tool to slip when tightening the screw, making it difficult to tighten or loosen the bolt. At the same time, the connection between the fixing plate 21 and the drive shaft 7 is also easily polished by the polishing liquid, affecting the strength of the connection. Therefore, as another embodiment of the present invention, it also includes a protective component, which is installed on the drive shaft 7 and the fixing plate 21, and the protective component is used to protect the connection between the bolt 19, the fixing plate 21 and the drive shaft 7.

[0038] In this embodiment, further, the protection component includes a protection cover 13, and a plurality of paddles 12 are provided on the protection cover 13. The protection cover 13 is sleeved on the drive shaft 7 and can rotate with the drive shaft 7. When the protection cover 13 rotates in the polishing liquid, the paddles 12 provide a downward thrust to the protection cover 13.

[0039] In this embodiment, further, the protection component also includes a locking mechanism, which is installed on the drive shaft 7. When the rotational speed of the drive shaft 7 reaches a specified rotational speed, the locking mechanism forms axial and radial positioning of the protection cover 13. When the rotational speed of the drive shaft 7 is lower than the specified rotational speed, the positioning of the protection cover 13 is released. Specifically, the locking mechanism includes a mounting ring 22 and a plurality of locking rods. The mounting ring 22 is arranged on the drive shaft 7 and its shape is adapted to the internal shape of the protective cover 13. The mounting ring 22 is provided with a plurality of radial mounting holes 23. The locking rod is arranged in the mounting hole 23. The locking rod includes a locking head 17 and a spring 16. One end of the spring 16 is fixedly connected to the bottom of the mounting hole 23, and the other end is fixedly connected to the locking head 17. The inner wall of the protective cover 13 is provided with a plurality of locking holes 18 that cooperate with the locking head 17. When the rotation speed of the drive shaft 7 reaches the specified rotation speed, the locking head 17 stretches the spring 16 into the locking hole 18 under the action of centrifugal force and cooperates with the locking hole 18 to form axial and radial positioning of the protective cover 13.

[0040] In the above scheme, the protective cover is first pushed upward to reveal the bolt hole, and then the wheel hub is fixed with bolts, and then the protective cover is put on the fixing plate, and then the rotating handle is turned to make the wheel hub enter the polishing liquid storage cylinder, and then the driving motor is turned on to drive the wheel hub to rotate. At the same time, the driving shaft will drive the protective cover to rotate. During the rotation of the protective cover in the polishing liquid, the paddle provides a downward thrust to the protective cover, thereby providing an axial positioning for the protective cover, and the rotating paddle has a stirring effect, which can evenly distribute the polishing particles in the polishing liquid in the polishing liquid storage cylinder to various places in the polishing liquid storage cylinder, preventing the polishing The polishing particles in the liquid are deposited at the bottom of the polishing liquid storage tube, so that the polishing can be more uniform; at the same time, when the rotation speed of the drive shaft 7 reaches the specified rotation speed, the locking head 17 stretches the spring 16 into the locking hole 18 under the action of centrifugal force and cooperates with the locking hole 18 to form axial and radial positioning of the protective cover 13. When the drive shaft stops rotating, the positioning of the locking mechanism is released, and at the same time, the thrust provided by the paddle to the protective cover disappears, the protective cover can be pushed up, and then the bolts are tightened to remove the wheel hub after polishing. The protective cover of this scheme is convenient to disassemble and assemble, which can provide protection while effectively improving work efficiency.

[0041] Furthermore, in order to improve the sealing between the fixed plate and the protective cover and further prevent the polishing liquid from entering the interior of the protective cover through the gap between the fixed plate and the protective cover, an annular mounting groove is provided on the fixed plate 21 at a position corresponding to the lower end surface of the protective cover 13, and a sealing ring 20 is provided in the annular mounting groove; at the same time, in order to improve the stability of the cooperation between the mounting ring and the protective cover, a plurality of axial positioning strips 2 are provided on the outer circumferential surface of the mounting ring 22, and a plurality of positioning grooves cooperating with the positioning strips 2 are provided on the inner wall of the protective cover 13.

[0042] Among them, in order to prevent the polishing liquid from being thrown out due to the rotation of the wheel hub when the wheel hub is polished, a plurality of mounting rods 6 are arranged on the lower end surface of the lifting plate 4, and a sealing cover 3 is arranged at the lower end of the mounting rod 6. A through hole is arranged on the sealing cover 3, and a bearing is arranged in the through hole. The inner ring of the bearing cooperates with the driving shaft 7. When the lifting plate drives the wheel hub to the specified position in the polishing liquid storage barrel, the sealing cover just covers the upper end of the polishing liquid storage barrel, thereby effectively preventing the polishing liquid from being thrown out.

[0043] The above description is only for the best embodiment of the present invention, but it should not be understood as limiting the claims. The present invention is not limited to the above embodiments, and its specific structure is allowed to be changed. All changes made within the scope of protection of the independent claims of the present invention are within the scope of protection of the present invention.
