Automatic sandpaper switching mechanism for pneumatic grinding and polishing machine

Abstract

The invention discloses an automatic sandpaper switching mechanism for a pneumatic grinding and polishing machine. The automatic sandpaper switching mechanism comprises a new sandpaper storage cylinder and an old sandpaper detaching cutter located beside the new sandpaper storage cylinder. A sandpaper conveying air cylinder for pushing sandpaper in the new sandpaper storage cylinder upwardly is arranged below the new sandpaper storage cylinder. The upper end of a new sandpaper discharging cylinder is open. According to the automatic sandpaper switching mechanism for the pneumatic grinding and polishing machine, by arranging the new sandpaper storage cylinder, the old sandpaper detaching cutter and the sandpaper conveying air cylinder for pushing the sandpaper in the new sandpaper storage cylinder upwardly, a robot moves a grinding and polishing head to the front of the old sandpaper detaching cutter, the robot moves slowly, the robot moves to the portion over new sandpaper after old sandpaper is torn down by the old sandpaper detaching cutter, the sandpaper is pressed on the grinding and polishing machine by the sandpaper conveying air cylinder, the robot moves away, and pasting of the new sandpaper is completed; and the robot continuously conducts grinding and polishing, and after the grinding and polishing are conducted multiple times, the actions mentioned above are repeated. By the adoption of the automatic sandpaper switching mechanism for the pneumatic grinding and polishing machine, automatic replacement of the sandpaper is achieved, no manual operation is needed, and the potential safety hazards existing in the prior art are solved.

Description

technical field [0001] The invention relates to a grinding device in the field of auto parts production and research, in particular to a sandpaper automatic switching mechanism for a pneumatic grinding and polishing machine. Background technique [0002] In the production of auto parts, parts need to be polished. The specific process is as follows: [0003] 1. Start the robot grinding and polishing system, and the robot enters the grinding state. When the grinding and polishing reaches a certain number of times, the robot moves the grinding and polishing head to the outside of the safety door; [0004] 2. The operator goes to the front door of the grinding and polishing head, manually tears off the old sandpaper, and then sticks the new sandpaper on it; [0005] 3. After the sandpaper is pasted, the operator's hand leaves the position of the grinding and polishing head; [0006] 4. Pneumatic equipment and robots continue to polish; [0007] 5. After grinding and polishin...
