Therefore, they should not be construed as limitations on this utility model.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-3 A polishing machine for a magnesium alloy laptop casing includes a base 1 and a laptop casing body 2. A horizontal conveyor 3 is fixedly mounted inside the base 1. A geared motor 9 is fixedly mounted on the upper front side of the base 1. A connecting rod 10 is fixedly connected to the drive shaft of the geared motor 9. A drive wheel 11 is coaxially fixedly connected to the connecting rod 10. A driven wheel 12 is coaxially fixedly connected to the transmission roller shaft of the horizontal conveyor 3. The drive wheel 11 and the driven wheel 12 are connected by a belt drive. The geared motor 9 drives the drive wheel 11 on the connecting rod 10 to rotate, which in turn drives the belt-connected driven wheel 12 to rotate. The driven wheel 12 drives the horizontal conveyor 3 to operate. A rectangular opening 13 is provided at the upper rear side of the center position of the base 1. The laptop shell body 2 is positioned directly opposite the rectangular opening 13. The conveyor belt of the horizontal conveyor 3 is positioned close to the rectangular opening 13. A discharge chute (not shown in the figure) is fixedly installed on the rear side wall of the base 1 facing the rectangular opening 13. The horizontal conveyor 3 is used to transport and transfer the laptop shell body 2 for polishing and grinding. After the laptop shell body 2 is polished and ground, it is guided through the rectangular opening 13 to the discharge chute (not shown in the figure) to facilitate the collection of polished laptop shell body 2.

[0022] A U-shaped bracket 4 is fixedly connected to the upper end of the base 1 near the rear side. A T-shaped seat 5 is fixedly connected to the upper end of the U-shaped bracket 4. A drive mechanism is provided on the front side wall of the T-shaped seat 5. The drive mechanism is provided with a U-shaped seat 6. The drive mechanism includes a first slot 14 located on the front side wall of the center position of the T-shaped seat 5. A cylinder 15 is fixedly installed in the first slot 14. The lower end of the piston rod of the cylinder 15 is fixedly connected to the upper end of the center position of the U-shaped seat 6. The cylinder 15 is used to drive the U-shaped seat 6 and the polishing roller 7 to move vertically up and down under the limiting action of the telescopic rod 17 in the second slot 16. This allows the drive motor 8 to drive the polishing roller 7 to rotate and polish the notebook shell body 2. The T-shaped seat 5 is located near the left and right sides. The front sidewall of each side is provided with a second slot 16. A limiting telescopic rod 17 is fixedly installed in each of the two second slots 16. The limiting telescopic rod 17 is used to limit the lifting and lowering of the U-shaped seat 6, so that it can be raised and lowered vertically smoothly, thereby enabling the polishing roller 7 to stably polish the notebook shell body 2. Connecting blocks 18 are fixedly connected to the left and right sidewalls near the upper end of the U-shaped seat 6. The lower ends of the two limiting telescopic rods 17 are fixedly connected to the two connecting blocks 18 respectively. The polishing roller 7 is fixedly installed in the U-shaped seat 6. A drive motor 8 is fixedly installed on the right sidewall of the U-shaped seat 6. The drive motor 8 is connected and fixed to the roller shaft of the polishing roller 7. The drive motor 8 is used to drive the polishing roller 7 to rotate.

[0023] A clamping mechanism is horizontally installed on the inner walls of the left and right sides of the base 1, which is located in front of the U-shaped bracket 4. The clamping mechanism includes hydraulic cylinders 19, which are fixedly installed on the left and right side walls of the base 1 respectively. The piston rods of the two hydraulic cylinders 19 are horizontally installed through the inner walls of the left and right sides of the base 1. The free ends of the piston rods of the two hydraulic cylinders 19 are fixedly connected to positioning blocks 20. The two positioning blocks 20 are located in front of the U-shaped bracket 4. The hydraulic cylinders 19 are used to drive the two positioning blocks 20 to abut against the notebook casing 2 on the horizontal conveyor 3, so that the notebook casing 2 is moved along the arc-shaped end face to the vertical section of the positioning blocks 20, thereby making the two positioning blocks 20 abut against the notebook casing. The outer casing 2 is clamped and positioned for quick and easy positioning of the laptop outer casing 2. Infrared controllers 21 are fixedly installed on the upper end of the base 1 opposite to the two hydraulic cylinders 19. The two infrared controllers 21 are set opposite to the horizontal conveyor 3 and are associated with the two hydraulic cylinders 19 respectively. The two infrared controllers 21 are used to identify the laptop outer casing 2 on the horizontal conveyor 3 and control the opening and closing of the two hydraulic cylinders 19. The two positioning blocks 20 have arc-shaped end faces on their opposite side walls near the lower end. The positioning blocks 20 are made of polyurethane rubber and can provide protection for clamping and positioning the laptop outer casing 2.

[0024] In use, the reduction motor 9 is started to drive the drive wheel 11 on the connecting rod 10 to rotate. The rotation of the drive wheel 11 drives the driven wheel 12 connected by the belt drive to rotate, and the driven wheel 12 drives the horizontal conveyor 3 to operate. The laptop shell body 2 is intermittently placed on the horizontal conveyor 3 for transfer. When the laptop shell body 2 moves to the side of the positioning block 20 with the horizontal conveyor 3, the infrared controller 21 activates the hydraulic cylinder 19. The hydraulic cylinder 19 drives the two positioning blocks 20 to abut against the side wall of the laptop shell body 2. When the arc-shaped end face of the positioning block 20 contacts the laptop shell body 2, the laptop shell body 2 is moved along the arc-shaped end face to the vertical section of the positioning block 20. Thus, the two positioning blocks 20 clamp and position the laptop shell body 2, which facilitates quick and easy assembly of the laptop shell body. The laptop casing 2 is positioned, and simultaneously, the cylinder 15 in the first slot 14 and the drive motor 8 on the U-shaped seat 6 are started by the external CNC electrical box (not shown in the figure). The cylinder 15 drives the U-shaped seat 6 and the polishing roller 7 to descend vertically under the limiting action of the limiting telescopic rod 17 in the second slot 16. The drive motor 8 drives the polishing roller 7 to rotate and perform contact polishing on the laptop casing 2, improving the polishing efficiency. After the laptop casing 2 is polished, the hydraulic cylinders 19 on both sides are started again to drive the two positioning blocks 20 to separate from the laptop casing 2. The laptop casing 2 falls back onto the horizontal conveyor 3 for transmission. The horizontal conveyor 3 guides the polished laptop casing 2 to the rectangular opening 13, so that it is discharged and collected along the discharge chute (not shown in the figure). There is no need for manual material handling, saving time and effort and reducing labor intensity.
