A V-shaped support structure is formed between the two supporting rotating wheels (203) on the holding end, and between the two supporting rotating wheels; 3)、待抛光管件旋转：3) Rotation of the pipe to be polished: ①旋转压轮(204)会在压紧气缸(205)的推力下向下压紧待抛光管件；①The rotating pressing wheel (204) will press down the pipe to be polished under the thrust of the pressing cylinder (205); ②旋转驱动电机(206)通电旋转，通过同步带带动旋转压轮(204)下方靠近旋转驱动电机输出端的支撑旋转轮(203)旋转，从而带动待抛光管件旋转；② The rotary drive motor (206) is energized and rotated, and the synchronous belt drives the support rotary wheel (203) below the rotary pressure wheel (204) near the output end of the rotary drive motor to rotate, thereby driving the pipe to be polished to rotate; 4)、去屑抛光头的调整：4), the adjustment of the chip removal polishing head: ①通过调节气缸(310)对第一调节过渡板(308)进行调整，能调整去屑抛光头(301)的高度；① By adjusting the first adjusting transition plate (308) by adjusting the cylinder (310), the height of the chip removing polishing head (301) can be adjusted; ②通过进给气缸(305)对抛光头固定座(302)进行调整，能调整去屑抛光头(301)的进给方向；② The polishing head fixing seat (302) can be adjusted by the feeding cylinder (305), so that the feeding direction of the chip removing polishing head (301) can be adjusted; 5)、抛光：5), polishing: ①当旋转驱动电机(206)通电旋转带动待抛光管件旋转时，进给气缸(305)推动第一滚珠型线性滑轨机构(303)的滑块带动去屑抛光头(301)进给，对待抛光管件内壁进行抛光；①When the rotary drive motor (206) is energized and rotated to drive the pipe to be polished to rotate, the feed cylinder (305) pushes the slider of the first ball-type linear slide mechanism (303) to drive the chip removal polishing head (301) to feed, and the to-be-polished polishing head (301) feeds. Polish the inner wall of the pipe fittings for polishing; ②抛光后，由吸屑装置通过吸屑口(6)将已抛光管件内的废屑吸出来；②After polishing, the waste chips in the polished pipe fittings are sucked out by the chip suction device through the chip suction port (6); 6)、下料：6), cutting: ①下料气缸推块(207)在下料气缸(208)的作用下顶起已抛光管件进行下料；① The blanking cylinder push block (207) pushes up the polished pipe fittings for blanking under the action of the blanking cylinder (208); ②下料气缸推块(207)顶部为斜面，当已抛光管件被顶起脱离支撑旋转轮(203)时，已抛光管件在重力的作用下会顺着下料气缸推块(207)的斜面顶部滚至下料排料机构(4)中，由下料排料机构(4)的下料槽(402)下料。②The top of the blanking cylinder push block (207) is an inclined surface. When the polished pipe is lifted off the supporting rotating wheel (203), the polished pipe will follow the inclined surface of the blanking cylinder push block (207) under the action of gravity. The top is rolled into the discharging and discharging mechanism (4), and the material is discharged from the discharging chute (402) of the discharging and discharging mechanism (4).
