[0003] Currently, several refrigerator compressor tubes are typically placed in a small cart with neat end faces. The end faces are then polished manually with a handheld grinder, followed by dust removal. The entire process involves high labor intensity for workers, and the metal dust has a significant impact on human health.

[0004] Therefore, there is an urgent need to develop an automatic chip removal device that can replace manual labor. Utility Model Content

[0012] Preferably, the bottom surface of the pressure plate is fixed with multiple rubber strips, and the rubber strips can press vertically onto the refrigerator compressor tube.

[0013] By adopting the above technical solution, the rubber strip can fill the gaps between the pipes, thereby allowing the pressure of the pressure plate to be applied evenly to the pipes.

[0031] Workers stack several refrigerator compressor tubes in the loading trolley 22, push the loading trolley 22 onto the turntable 231 and limit its position. The leveling cylinders 24 on both sides push the leveling plate 241 against the end face of the tube to ensure that the end face of the tube is neat. The pressing cylinder 233 drives the pressing plate 234 to press the tube from the top. Then, the stepper motor 27 drives the turntable 231 to rotate the loading trolley 22 90 degrees. The flipping component 26 drives the baffle 25 to fall down. The baffle 25 can push against the end of the tube. Then, the robotic arm 1 drives the grinder 12 to automatically grind the end face of the tube. After the grinding is completed, the flipping component 26 drives the baffle 25 to flip up. The robotic arm 1 drives the blower 11 to blow dust from the end face of the tube. The surface dust and the dust inside the tube can be blown into the dust collection hood 3.

[0032] After that, the turntable 231 drives the tube to rotate again and repeats the above actions, which can remove chips from the other end of the tube. The whole process is highly automated and has a good chip removal effect.
