[0031] The following is a more detailed description of the automotive parts surface polishing device of the utility model in conjunction with the schematic diagram, which shows the preferred embodiment of the utility model. It should be understood that those skilled in the art can modify the utility model described herein and still achieve the beneficial effects of the utility model. Therefore, the following description should be understood as being widely known to those skilled in the art and not as a limitation to the utility model.

[0032] The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the accompanying drawings are in very simplified form and in non-precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0033] like Figure 1 and Figure 2 As shown, an embodiment of the utility model provides an automobile parts surface polishing device, including a frame 1, a grinding component 2 and a blowing component 3.

[0034] Among them, the grinding assembly 2 includes a movable plate 21, a driving shaft 22 and a grinding disc 23. The movement of the movable plate 21 drives the grinding disc 23 to move in the horizontal direction and the vertical direction, so that the grinding disc 23 can contact and grind the automobile parts and feed along the size direction of the automobile parts to complete the grinding of the surface of the automobile parts.

[0035] One end of the driving shaft 22 is rotatably connected to the movable plate 21 , and the other end is fixedly connected to the grinding disc 23 , that is, the grinding disc 23 is rotated by the rotation of the driving shaft 22 , thereby completing the grinding of the surface of the automobile parts.

[0036] In addition, the blowing assembly 3 is disposed on the movable plate 21 , located on both sides of the grinding disc 23 , and connected to the driving shaft 22 .

[0037] It should be particularly noted that when the drive shaft 22 rotates, the blowing assembly 3 is controlled to periodically spray air toward both sides of the grinding disk 23, that is, when the drive shaft 22 rotates, the blowing assembly 3 is synchronously driven to operate, so that the surfaces of the automobile parts located on both sides of the grinding disk 23 can be affected by the wind and the debris formed by the grinding of the grinding disk 23 can be blown away. Therefore, when the grinding disk 23 contacts and grinds the surface, a clean surface can be provided to avoid the situation where the surface grinding effect is poor due to excessive adhesion of debris, thereby achieving the purpose of improving the grinding quality.

[0038] The device is provided with a grinding component 2 including a movable plate 21, a driving shaft 22 and a grinding disc 23, and the surface of the automobile part is polished by means of the grinding disc 23. The blowing component 3 is provided and connected to the driving shaft 22, so that when the driving shaft 22 drives the grinding disc 23 to rotate and grind, the blowing component 3 can blow toward both sides of the grinding disc 23, so that the surfaces of the automobile parts on both sides of the grinding disc 23 are always in a clean state, that is, the debris formed by the grinding of the grinding disc 23 will not adhere to the surface of the automobile part to be polished, thereby improving the effect of the subsequent moving feeding grinding of the grinding disc 23 and achieving the purpose of improving the grinding quality.

[0039] In a further embodiment, a specific blowing assembly 3 is also proposed to better blow air to both sides of the grinding disc 23, thereby improving the cleanliness of the surface of the automobile parts on both sides of the grinding disc 23, thereby improving the quality of subsequent grinding.

[0040] Specifically, the blowing assembly 3 includes a fixed sleeve 31 with an air outlet 311 at the bottom and a piston push rod 32 .

[0041] The fixed sleeve 31 is fixedly mounted on the lower surface of the movable plate 21 and communicated with the movable plate 21 , and has a one-way air inlet valve and a one-way air outlet valve.

[0042] The piston push rod 32 is slidably installed inside the fixed sleeve 31, and one end extends to the upper surface of the movable plate 21. Therefore, when the piston push rod 32 moves back and forth in the fixed sleeve 31, the gas can be reciprocatingly discharged from the air outlet 311, thereby ensuring the cleanliness of the surface of the automobile parts on both sides of the grinding disc 23 and improving the subsequent grinding quality.

[0043] In addition, in order to facilitate the control of the reciprocating movement of the piston push rod 32 , the blowing assembly 3 further includes a rotating disk 33 and a hinged rod 34 .

[0044] The rotating disk 33 is rotatably mounted above the movable plate 21 through a positioning seat, and the rotation direction of the rotating disk 33 is perpendicular to the rotation direction of the driving shaft 22 . One end of the hinged rod 34 is hinged to the edge of the rotating disk 33 , and the other end is hinged to the piston push rod 32 .

[0045] A crank slider mechanism is formed between the rotating disk 33 , the hinged rod 34 and the piston push rod 32 , so when the rotating disk 33 rotates, the hinged rod 34 controls the piston push rod 32 to move back and forth in the fixed sleeve 31 .

[0046] In order to synchronously control the rotation of the rotating disk 33 when the driving shaft 22 is running, a linkage member 4 is further provided.

[0047] Specifically, the rotating disk 33 is connected to the driving shaft 22 via a linkage member 4, so that when the driving shaft 22 rotates, the rotating disk 33 is synchronously driven to rotate.

[0048] The linkage member 4 includes a first bevel gear 41 and a second bevel gear 42 .

[0049] The first bevel gear 41 is fixedly mounted on the outer wall of the driving shaft 22, and the second bevel gear 42 is fixedly connected to the rotating disk 33 via a connecting shaft, and shares a common axis, and meshes with the first bevel gear 41. When the driving shaft 22 rotates, the rotating disk 33 is synchronously driven to rotate under the meshing action of the first bevel gear 41 and the second bevel gear 42, so as to realize the reciprocating movement of the piston push rod 32, and then realize the reciprocating discharge of gas, so as to blow air to the surfaces of the automobile parts on both sides of the grinding disk 23 for cleaning, and ensure the quality of subsequent feeding and grinding.

[0050] It should be noted that the air outlet 311 is configured as a trumpet-shaped structure to expand the blowing range and enhance the effect of removing debris.

[0051] In other embodiments, one end of the driving shaft 22 is connected to an output motor for controlling the rotation of the driving shaft 22 .

[0052] In a further embodiment, in order to facilitate the positioning of automobile parts and prevent the automobile parts from tilting during the grinding process, thereby causing poor grinding effect, a positioning fixture 5 is provided inside the frame 1.

[0053] Specifically, the positioning fixture 5 includes two symmetrically arranged cylinder clamps, which is a prior art and will not be described in detail here.

[0054] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
