[0026] As Figures 1-5 shown, the embodiment of the utility model provides a kind of electric vehicle frame surface polishing device, including top frame 2:

[0027] The middle position of the bottom end of the top frame 2 is fixedly provided with a connecting rod 16, the bottom end of the connecting rod 16 is fixedly provided with a movable ball 17, the movable ball 17 is movably connected with a movable ball clamping groove 15, the movable ball clamping groove 15 is arranged in the middle position of the top end of the bottom box 8, the top end of the bottom box 8 is fixedly provided with a bottom frame 4, the top end of the bottom frame 4 is fixedly provided with a stop disc 13, the bottom frame 4 and the stop disc 13 are both provided with a through hole 14, the connecting rod 16 is connected with the through hole 14, the bottom end of the top frame 2 is fixedly provided with a plurality of spring stop rods 11, the bottom end of each spring stop rod 11 is fixedly provided with a stop column 12, the bottom end of each stop column 12 is in contact with the top of the stop disc 13, and the bottom of the bottom box 8 is fixedly provided with a grinding machine 6.

[0028] Specifically, the four corner positions of the bottom end of the top frame 2 are fixedly provided with buffer spring columns 5, the bottom end of each buffer spring column 5 is fixedly provided with a horseshoe-shaped rubber leg pad 7.

[0029] Specifically, the middle positions of the two sides of the top frame 2 are fixedly provided with side frames 3, the bottom end of each side frame 3 is fixedly provided with a stop rod 10, the middle positions of the two sides of the bottom frame 4 are both provided with a letting groove 9, and the two stop rods 10 are connected with the corresponding letting grooves 9.

[0030] Specifically, the middle position of the top end of the top frame 2 is fixedly provided with a handle 1.

[0031] Specifically, the size of the letting groove 9 is matched with the size of the stop rod 10.

[0032] Working principle:

[0033] When the power is turned on, the grinder 6 fixedly installed at the bottom of the bottom box 8 is started to rotate at high speed, and the grinding disc is ready for grinding. Since the four spring abutting rods 11 are arranged at the bottom end of the top frame 2, the bottom end of the abutting column 12 of the spring abutting rod 11 is in contact with the top of the abutting disc 13. When the device falls, the spring abutting rod 11 can provide buffering, and can also support the top frame 2 and the bottom frame 4 when the bottom frame 4 changes the inclination angle. The bottom end of the connecting rod 16 is provided with a movable ball 17, which is movably connected with the movable clamping ball groove 15 at the top end of the bottom box 8, allowing the grinder 6 to be flexibly adjusted in the transverse direction. When the device is pressed against the surface of the vehicle frame, the grinder 6 automatically adjusts the angle of the grinding disc to adapt to the curved part of the vehicle frame, ensuring the best fit. During the grinding process, the four buffer spring columns 5 are fixedly arranged at the bottom end of the four corners of the top frame 2, and the bottom end of the buffer spring column 5 is fixedly provided with a horseshoe-shaped rubber leg pad 7, so that the surface of the vehicle frame can be effectively stabilized and fixed. The side frame 3 is fixedly arranged at the middle position of the two sides of the top frame 2, and the bottom end of the side frame 3 is provided with a stop rod 10. The stop rod is inserted and connected with the let-in groove 9 at the two sides of the bottom frame 4, which plays a role in transverse guidance, ensuring that the device remains stable during grinding and does not deviate. The size of the let-in groove 9 matches the stop rod 10, so that the grinder 6 can move smoothly along the set trajectory. Since the grinder 6 is installed at the bottom of the bottom box 8, the grinding disc is in contact with the surface of the vehicle frame after a certain pressure is applied, and automatically adjusts the angle with the curved surface of the vehicle frame. The operator slowly moves the grinding device along the shape of the vehicle frame, so that the grinding disc covers the entire surface of the vehicle frame in sequence, ensuring uniform grinding.

[0034] Each of the embodiments in the specification is described in a progressive manner, and the same and similar parts between the embodiments can be referred to each other. Each embodiment focuses on the difference from other embodiments. In particular, the system embodiment is described more simply because it is basically similar to the method embodiment, and the relevant part can be referred to the part of the method embodiment.

[0035] The above only describes the embodiments of the present application and is not used to limit the present application. The present application can be variously changed and modified by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the scope of the claims of the present application.
