[0030] As a technical optimization of this utility model, a first fixing plate 7 is installed on the top of the second frame box 2. The top end of the inner wall of the sleeve 6 is slidably connected to the top end of the first fixing plate 7. A fixing member 34 is fixedly installed on the side of the first fixing plate 7 away from the first frame box 1. The fixing member 34 is located at the end near the conveyor belt 3. A movable member 37 is slidably installed on the side of the first fixing plate 7 away from the first frame box 1. The movable member 37 is located at the end away from the conveyor belt 3. The side of the movable member 37 away from the first fixing plate 7 is connected to the inner wall of the sleeve 6.

By rotating the lead screw 36 driven by the rotary motor 35, the movable member 37 can be moved, thereby driving the sleeve 6 to move on the first fixing plate 7, which facilitates the operation of the device under various operational requirements.

[0031] As a technical optimization of this utility model, third support legs 10 are installed at both ends of the top of the second frame box 2. A first guide rail 11 is installed on the top of the third support leg 10, and a first fixing block 39 is slidably installed on the top of the first guide rail 11. The top of the first fixing block 39 is connected to the bottom of the first fixing plate 7. A second support leg 8 is installed between the two third support legs 10. A first cylinder 9 is installed on the top of the second support leg 8. The telescopic end of the first cylinder 9 faces the first frame box 1, and a second fixing block 40 is installed on the telescopic end of the first cylinder 9. The top of the second fixing block 40 is connected to the bottom of the first fixing plate 7. By extending and retracting the telescopic end of the first cylinder 9, the first fixing plate 7 can be moved, facilitating the device to operate accordingly under various operational requirements. The third support legs 10 and the first guide rail 11 make the operation of the first fixing plate 7 more stable.

[0032] As a technical optimization of this utility model, a second fixing plate 29 is installed on the top of the end of the sleeve 6 near the conveyor belt 3. A connecting plate 30 is installed on the top of the second fixing plate 29. A moving block 31 is slidably installed on the top of the connecting plate 30. A second cylinder 28 is installed on the end of the second fixing plate 29 away from the first frame box 1. The telescopic end of the second cylinder 28 is connected to the moving block 31. Two first grippers 25 are hinged on the top of the end of the second fixing plate 29 away from the second cylinder 28, and a spring steel plate is provided at the hinge. The two first grippers 25 are provided with slots 33 on the side that is close to each other. A pulley 32 is rotatably installed on the top of the end of the two first grippers 25 near the moving block 31. The outer side of the pulley 32 abuts against the side wall of the moving block 31. The telescopic end of the second cylinder 28 pulls the moving block 31. At this time, the tip of the moving block 31 abuts against the pulley 32. The first gripper 25 opens under the action of the spring steel plate. Then the first cylinder 9 pushes the first fixed plate 7, so that the first gripper 25 moves closer to the housing workpiece 5 above the placement plate 24. When the housing workpiece 5 is located inside the slot 33, the second cylinder 28 pushes the moving block 31, so that the moving block 31 squeezes the pulley 32. At this time, the two first grippers 25 move closer to each other and clamp the housing workpiece 5 located inside the slot 33.

[0033] In use, all the electric drive mechanisms in this device are controlled by a preset control system. The tension of the first grinding belt 19 and the second grinding belt 20 is adjusted by preset tensioning wheels. The first grinding belt 19 is for coarse grinding, and the second grinding belt 20 is for polishing. The first gripper 25, the second gripper 26 and the third gripper 27 have the same structure. Therefore, only the structure and installation method of the first gripper 25 are described. The first frame box 1 has a discharge port on the side away from the conveyor belt 3.

[0034] The housing workpiece 5 is transported by the conveyor belt 3. When the housing workpiece 5 abuts against the baffle 23, the electric telescopic rod 21 is activated and extends, pushing the housing workpiece 5 above the placement plate 24. Subsequently, the first cylinder 9 is activated, driving the first fixed plate 7 to move away from the first frame box 1. When the first fixed plate 7 moves to the preset position, the rotary motor 35 is activated, driving the lead screw 36 to rotate, causing the sleeve 6 to move closer to the conveyor belt 3. When the sleeve 6 moves to the preset position, the rotary motor 35 stops operating. At this time, the second cylinder... The telescopic end of cylinder 28 pulls the moving block 31. At this time, the tip of the moving block 31 abuts against the pulley 32. The first gripper 25 opens under the action of the spring steel plate. Then, the first cylinder 9 pushes the first fixed plate 7, so that the first gripper 25 moves closer to the housing workpiece 5 above the placement plate 24. When the housing workpiece 5 is located inside the slot 33, the second cylinder 28 pushes the moving block 31, so that the moving block 31 squeezes the pulley 32. At this time, the two first grippers 25 move closer to each other and clamp the housing workpiece 5 located inside the slot 33.

[0035] Subsequently, the sleeve 6 moves away from the conveyor belt 3. When the first gripper 25 moves to the gap between the two first grinding belts 19, the two first grippers 25 move away from each other, placing the shell workpiece 5 on the top of the lower first grinding belt 19. Then, the sleeve 6 moves away from the first frame box 1 again. When it moves to the preset position, the sleeve 6 moves closer to the conveyor belt 3 again. When the sleeve 6 moves to the preset position, the first gripper 25 moves towards the placement plate 24 again and clamps another shell workpiece 5. When the first gripper 25 clamps a new shell workpiece 5 again, the second gripper 26 is located on the shell workpiece 5 on the first grinding belt 19. The second gripper 26 adopts the same operation method as the first gripper 25 and can clamp the shell workpiece 5 at this location. At this time, the first drive wheel 13 and the second drive wheel 14 rotate to perform rough grinding on the shell workpiece 5 at this location.

[0036] Subsequently, the first gripper 25 clamps the new housing workpiece 5 and transfers it to the first grinding belt 19, while the second gripper 26 clamps the housing workpiece 5 on the first grinding belt 19 and transfers it to the second grinding belt 20. At this time, the first gripper 25 repeats the above operation steps to clamp the new housing workpiece 5. When the first gripper 25 clamps the new housing workpiece 5, the second gripper 26 and the third gripper 27 also clamp the housing workpiece 5 on the first grinding belt 19 and the second grinding belt 20 at the same time. Meanwhile, under the rotation of the first drive wheel 13 and the second drive wheel 14, the housing workpiece 5 on the first grinding belt 19 is coarsely ground, and the housing workpiece 5 on the second grinding belt 20 is polished. When the third gripper 27 moves to the unloading port set on the side of the first frame box 1 away from the conveyor belt 3, the third gripper 27 lowers the polished housing workpiece 5, completing the automatic unloading of the housing workpiece 5.

[0037] Subsequently, the first gripper 25, the second gripper 26 and the third gripper 27 repeat the above operation steps. Combined with the feeding of the conveyor belt 3, the grinding of the shell workpiece 5 can be automated, which can greatly improve the grinding efficiency of the shell workpiece 5.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
