[0029] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0030] Example 1

[0031] See also Figure 1-4A polishing device for a vehicle-mounted navigation system shell includes a polishing box 100 and a rotating lifting cylinder 500; wherein, a cylinder 102 is vertically fixedly connected to the center of the inner bottom of the polishing box 100, and a spiral groove 103 is provided on the surface of the cylinder 102; the rotating lifting cylinder 500 is slidably sleeved on the cylinder 102, and a cylindrical slider 505 is fixedly connected to the side wall of the inner hole 503 of the rotating lifting cylinder 500, and the slider 505 is slidably installed in the spiral groove 103; the rotating lifting cylinder 500 is driven by an electric push rod 301 and can be rotated and lifted on the cylinder 102; a clamping member 600 for clamping a vehicle-mounted navigation system shell 700 is fixedly connected to the outer surface of the rotating lifting cylinder 500. It also includes a DSP controller 200, the electric push rod 301 is controlled by the DSP controller 200, and the DSP controller 200 is installed on one side of the polishing box 100; wherein the inner wall of the polishing box 100 is coated with a wear-resistant aluminum oxide coating; the rotating lifting cylinder 500 and the cylinder 102 are both made of wear-resistant high manganese steel.

[0032] When in use, a suspended polishing liquid (polishing liquid) is added into the polishing box 100, and the suspended polishing liquid is selected from silicon oxide suspended polishing liquid (sand suspension) or aluminum oxide suspended polishing liquid.

[0033] The vehicle navigation system housing 700 is clamped and fixed on the rotating lifting cylinder 500 by the clamping member 600, and then the rotating lifting cylinder 500 is sunk into the polishing box 100, and then lifted up and down by the electric push rod 301, so that the vehicle navigation system housing 700 is surface polished during the rotating lifting process.

[0034] Specifically, Figure 1 As shown in the figure, the upper end of the rotating lifting cylinder 500 is rotatably connected to one end of the connecting plate 302 through the turntable bearing 400, and the other end of the connecting plate 302 is fixedly connected to one end of the piston rod of the electric push rod 301, and the electric push rod 301 is vertically fixedly installed on one side of the outer wall of the polishing box 100 through the mounting seat 300. Among them, the outer ring of the turntable bearing 400 is fixedly connected to the top of the rotating lifting cylinder 500, and the outer ring of the turntable bearing 400 and the center of the rotating lifting cylinder 500 are on the same vertical line; the inner ring of the turntable bearing 400 is fixedly connected to the bottom of one end of the connecting plate 302.

[0035] like Figure 2 As shown in FIG. 5 , a strip-shaped exhaust port 501 is provided on one side of the upper end of the rotary lifting cylinder 500. The design of the exhaust port 501 facilitates the flow of gas in the inner hole 503 of the rotary lifting cylinder 500, so that the rotary lifting cylinder 500 can be smoothly lifted up and down.

The upper part of the clamping bolt 601 is rotatably sleeved with the clamping plate 602, and the lower part of the clamping bolt 601 is sleeved with a wear-resistant elastic rubber sleeve 603. The elastic rubber sleeve 603 is set as a fluororubber sleeve. The clamping bolt 601 is set as a butterfly bolt.

[0039] In practice, by tightening the clamp bolts 601, the vehicle-mounted navigation system housing 700 can be clamped between the fixing plate 502 and the clamping plate 602. The fixing plate 502 and the clamping plate 602 are clamped by a clamping force.

[0040] The above clamping method may be loose when the rotation speed is too fast. When implemented, it can also be adjusted according to the specific shape of the vehicle navigation system housing 700, such as Figure 4 As shown in , the clamping bolt 601 can be passed through the button mounting hole 701 on the vehicle-mounted navigation system housing 700 and then locked, which is more stable.
