[0023] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0024] Reference Figure 1-5 The utility model embodiment is an automatic car paint grinding machine, which includes: a shell 1, which serves as the main structure of the entire device and protects the internal components. The upper top wall of the shell 1 is fixedly connected with a mounting plate 6 for mounting a fixed motor 7. The inside of the mounting plate 6 is fixedly connected with the motor 7 for driving the upper rotating shaft 8 to rotate. The motor 7 is located below the mounting plate 6. The output end of the motor 7 is fixedly connected with the upper rotating shaft 8 for receiving the power of the motor 7 and rotating. The upper rotating shaft 8 is provided with a cavity 9 for the spring 10 and the lower rotating shaft 11. The upper rotating shaft 8 is internally movably connected with the lower rotating shaft 11 for connecting the grinding wheel 4. The side surface of the lower rotating shaft 11 is provided with a protrusion 15 for cooperating with the groove 14 to drive the lower rotating shaft 11 to rotate. The inner wall of the cavity 9 is provided with a groove 14 for cooperating with the protrusion 15 to drive the lower rotating shaft 11 to rotate. The protrusion 15 is located inside the groove 14. The blocking plate 12 is located directly above the groove 14 and the protrusion 15. The upper end of the lower rotating shaft 11 is fixedly connected with the blocking plate 12 for preventing the lower rotating shaft 11 from falling off the upper rotating shaft 8.

[0025] A spring 10 is fixedly connected to the upper end of the blocking plate 12 for providing a certain elastic force. The spring 10 and the blocking plate 12 are both located inside the cavity 9. A grinding wheel 4 is fixedly connected to the lower end of the lower rotating shaft 11 for grinding the surface of the car. A fixing groove 13 is provided on the inner wall of the outer shell 1 for limiting the fixation of the limit plate 5. The inner wall of the outer shell 1 is fixedly connected to the limit plate 5 for limiting the position of the lower rotating shaft 11. A limiting hole is provided on the upper surface of the limit plate 5 for ensuring smooth rotation of the lower rotating shaft 11. The lower rotating shaft 11 passes through the limiting hole. The limit plate 5 is located inside the fixing groove 13. The upper rotating shaft 8 and the motor 7 are both located directly above the limit plate 5.
