DETAILED DESCRIPTION

[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0026] Reference Figures 1 to 6 As shown, an engine decorative cover polishing device of the utility model comprises a polishing plate 1;

[0027] A clamping mechanism 2, used for clamping the engine decorative cover;

[0028] The polishing plate 1 has two grooves 11 in the middle, and a groove 2 12 in the rear. The bottom wall of the polishing plate 1 is fixedly connected to a support frame 21, and the upper end of the support frame 21 is fixedly connected to a motor 22. The output end of the motor 22 is fixedly connected to a connecting block 23, and both ends of the connecting block 23 are rotatably connected to connecting rods 24, and the other end of the connecting rod 24 is rotatably connected to a clamping plate 25; the inner surface of the groove 2 12 is rotatably connected to a moving mechanism 3, and the upper part of the moving mechanism 3 is slidably connected to a polishing mechanism 4.

[0029] In order to achieve the purpose of clamping the engine decorative cover, during operation, the motor 22 is supported by the support frame 21 installed at the bottom of the polishing plate 1, and the motor 22 rotates to drive the connecting block 23 to drive the two connecting rods 24 to move. The two connecting rods 24 move at the same time, which can control the two clamping plates 25 to move at the same time. The clamping plate 25 on the polishing plate 1 can clamp the engine decorative cover. The clamped engine decorative cover cannot move, which is convenient for the next step to accurately polish the engine decorative cover;

[0030] The moving mechanism 3 can control the movement of the polishing mechanism 4, so that the device can adjust the position of the polishing mechanism 4 according to the position of the engine decorative cover that needs to be polished.

[0031] Reference Figure 3 As shown, in one embodiment of the utility model, a groove four 27 is provided at the lower portion of the clamping plate 25, and a groove three 26 is provided at the clamping plate 25 located below the groove four 27. The groove four 27 is slidably mounted on the inner surfaces of the two grooves one 11, and one end of the connecting rod 24 is rotatably mounted on the inner surface of the groove three 26.

[0032] In order to achieve the purpose of polishing the engine decorative cover by the splint 25, the two connecting rods 24 are rotatably installed on the inner surface of the groove three 26. When the motor 22 rotates, it is transmitted through the connecting block 23 and moves the two connecting rods 24 at the same time. Since the groove four 27 on the splint 25 is slidingly connected to the polishing plate 1, the two connecting rods 24 can move with the two splints 25 at the same time. When the two splints 25 move toward each other, the engine decorative cover placed on the polishing plate 1 can be clamped. When the two splints 25 move away from each other, the clamping of the engine decorative cover is released, and the engine decorative cover can be taken out at this time.

[0033] Reference Figure 4 As shown, in one embodiment of the utility model, the moving mechanism 3 includes a threaded rod 31, which is rotatably mounted on the inner surface of the second groove 12, and the outer surface of the threaded rod 31 is threadedly connected with an L-shaped connecting rod 32, and the L-shaped connecting rod 32 is slidably mounted on the inner surface of the second groove 12.

[0034] In order to achieve the purpose of moving the polishing mechanism 4, since the threaded rod 31 is rotatably installed in the groove 2 12, and the threaded rod 31 and the lower part of the L-shaped connecting rod 32 are threadedly connected, the threaded rod 31 can be rotated according to the position of the engine decorative cover to be polished, and the position of the polishing mechanism 4 can be adjusted to polish the engine decorative cover. In actual use, the threaded rod 31 can be driven by a motor, and the threaded rod 31 is fixedly connected to the motor output shaft, so that the motor can control the rotation of the threaded rod 31.

[0035] Reference Figure 5As shown, in one embodiment of the utility model, a groove 5 321 is opened on the upper part of the L-shaped connecting rod 32, and an electric telescopic rod 41 is fixedly installed on the inner surface of the groove 5 321. One end of the electric telescopic rod 41 is fixedly connected to a slider 42, and the slider 42 is slidably installed on the inner surface of the groove 5 321, and the lower end of the slider 42 is fixedly connected to a cylinder 43.

[0036] In order to achieve the purpose of adjusting the polishing mechanism 4 according to the engine decorative cover, the position of the slider 42 is controlled by the electric telescopic rod 41 installed in the groove 5 321. The bottom of the slider 42 is connected to the cylinder 43. The position of the cylinder 43 can be adjusted by the electric telescopic rod 41. Since the heights of different positions of the engine decorative cover are different, the height of the polishing assembly can be adjusted according to the different surface structures of the engine decorative cover through the piston rod of the cylinder 43, so as to achieve the purpose of precise polishing of the engine decorative cover.

[0037] Reference Figure 6 As shown, in one embodiment of the utility model, the piston rod of the cylinder 43 is fixedly connected to a motor 2 44, the output end transmission shaft of the motor 2 44 is fixedly connected to a connecting sleeve 45, the lower end of the connecting sleeve 45 is fixedly connected to a polishing ball 46, and the polishing ball 46 is a sphere with a rough surface.

[0038] In order to achieve the purpose of polishing the engine decorative cover, the motor 2 44 connected to the piston rod end of the cylinder 43 controls the connecting sleeve 45. The connecting sleeve 45 serves as an intermediary between the polishing ball 46 and the motor 2 44. Its function is to facilitate the installation and replacement of polishing balls 46 with different surface roughness according to actual conditions. The polishing ball 46 is a sphere with a rough surface. According to the different polishing requirements for different positions of the engine decorative cover, the polishing balls 46 with different surface roughness are replaced.

[0039] Working principle:

[0040] First, place the engine decorative cover on the support plate 1, start the motor 22, and under the action of the motor 22, drive the two connecting rods 24 to move through the connecting block 23. The two connecting rods 24 are rotatably installed on the inner surface of the groove three 26, and the two clamping plates 25 are slidably connected with the groove 11 on the polishing plate 1. Under the action of the connecting rod 24, the two clamping plates 25 move at the same time to clamp and fix the engine decorative cover to prevent it from sliding during the polishing process and affecting the polishing accuracy.

[0041] After the engine decorative cover is fixed, the threaded rod 31 is rotated according to the polishing position of the engine decorative cover. Since the threaded rod 31 and the L-shaped connecting rod 32 are threadedly connected, the position of the L-shaped connecting rod 32 can be adjusted by rotating the threaded rod 31. When the L-shaped connecting rod 32 is driven to reach above the position to be polished by rotating the threaded rod 31, the electric telescopic rod 41 pushes the slider 42 to adjust the position of the cylinder 43, and the piston rod of the cylinder 43 adjusts the position of the polishing ball 46 according to the distance between the polishing ball 46 and the engine decorative cover, so that the polishing ball 46 can contact the engine decorative cover to polish it. During the polishing process, the cylinder 43 controls the extension length of the piston rod and replaces the polishing ball 46 with different surface roughness to control the polishing accuracy.

[0042] Obviously, the above embodiments are merely examples for clear explanation and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from them are still within the protection scope of the invention of the utility model.
