[0002] Mechanical polishing is a polishing method that uses abrasives to cut the convex parts of the material surface to obtain a smooth surface. Generally, abrasives used are oilstone strips, wool wheels, sandpaper, etc. The advantages of mechanical polishing are good flatness and high brightness of the parts after processing. It is more suitable for processing simple parts, medium and small products. During polishing, the high-speed rotating polishing wheel (circumferential speed of more than 20 m / s) presses against the workpiece, causing the abrasive to roll and slightly cut the surface of the workpiece, thereby obtaining a bright processed surface.

[0051] Working principle:

[0052] When the surface of the U-shaped stainless steel tube is polished, one end of the U-shaped stainless steel tube is placed inside the clamping block 405, and the driving ends of the two electric push rods 407 respectively push the two clamping plates 406 to clamp the surface of the U-shaped stainless steel tube, and the driving end of the servo electric cylinder 50 pushes the movable frame 40 to move downward until the U-shaped stainless steel tube and the polishing assembly are at the same level, and one end of the U-shaped stainless steel tube is sent into the polishing frame 101;

[0053] The position of the polishing assembly is adjusted according to the diameter of the pipe. The adjusting rod 201 is rotated clockwise.

[0055] After the pipe fitting is sent into the polishing frame 101, the output end of the driving motor 302 drives the double gear 303 to rotate, and the meshing transmission relationship between the double gear 303 and the surfaces of the two polishing frames 101 is used to make the two polishing frames 101 rotate synchronously inside the fixed frame 30. At this time, the polishing sheet 103 rotates on the surface of the pipe fitting to polish the surface of the pipe fitting. At the same time, the electric slide 401 in the movable frame 40 drives the U-shaped stainless steel pipe to move in the Y-axis direction, and the mounting frame 403 drives the U-shaped stainless steel pipe to move in the X-axis direction. The output end of the steering motor 404 drives the U-shaped stainless steel pipe to rotate in the horizontal direction, and the other end of the U-shaped stainless steel pipe passes through the inside of the polishing frame 101 until two-thirds of the U-shaped stainless steel pipe passes through the inside of the polishing frame 101. The clamping block 405 is used to polish the other end of the U-shaped stainless steel pipe, and then all the surfaces of the U-shaped stainless steel pipe are polished.
