When the lifting plate 33 is lowered to the lower end, the inner ring of the tubular member is polished by the polishing head, and the tubular member conveyed at the leftmost end is sent out of the conveyor belt 22 during the conveyance by the conveyor belt 22. The sent tubular member 100 automatically falls into the receiving hoppers 63 under the action of gravity, when one receiving hopper 63 is full of receiving materials, the empty receiving hopper 63 can be horizontally pushed to the lower part of the discharge port of the conveying belt 22 along the conveying direction of the feeding roller, and the receiving hopper 63 full of the tubular member is pushed to wait for subsequent processing or packaging; dust generated by polishing enters the receiving hopper 63 along with the tubular member and enters the waste hopper 62 through the screen hole. The tubular member held by the jig 51 is rubbed against the polishing sandpaper to polish the bottom end of the tubular member, and the tubular member on the right side of the held tubular member is continuously conveyed along the conveyor belt 22 from right to left. When the clamped tubular member is polished according to the time set by the controller, the positioning cylinder 52 drives the positioning clamp 51 to reset. At the same time, the lifting plate 33 drives the polishing shaft to rise to the high end, the swing rod 43 drives the trigger switch to fall to the low end and align with the conveying cavity, and the cycle is repeated.

The multi-functional polishing apparatus as set forth in claim 1, characterized in that: the polishing device comprises a lifting plate, a polishing frame, a polishing mechanism, a lifting cylinder, a polishing mechanism and a polishing mechanism, wherein the lifting plate is driven by the lifting mechanism, the lifting mechanism comprises a lifting cylinder and a fixed block, the lifting cylinder is fixedly arranged on the lifting plate, the movable end of the lifting cylinder faces downwards, the fixed block is fixed on the polishing frame below the lifting cylinder, and the movable end of the lifting cylinder is connected with the fixed block; longitudinal slide rails are respectively installed on two sides of the front end of the polishing frame, sliding blocks are respectively installed on the left side and the right side of the lifting plate, two ends of the lifting plate are respectively arranged on the longitudinal slide rails on the corresponding sides through the sliding blocks, and the lifting plate can slide up and down along the extending direction of the longitudinal slide rails.
5. The polishing method of the multifunctional polishing apparatus as set forth in claim 3, wherein: the tubular pieces to be polished are placed on the conveying belt one by one and conveyed from right to left along the conveying belt, the lifting cylinder drives the lifting plate to rise to the high end, the lifting plate drives one end of the swinging rod to lift up through the connecting rod, and the swinging rod rotates around the pin shaft piece to enable the trigger switch to fall to the low end and align to the conveying cavity; when the tubular piece at the leftmost end of the conveying belt is conveyed to the outlet of the conveying cavity and is contacted with the trigger switch, the information of the trigger switch is conveyed to the controller, the conveying belt is controlled to stop conveying through the controller, and meanwhile, the two positioning cylinders drive the positioning clamps at the corresponding sides to move to one side of the conveying belt, so that the second tubular piece conveyed at the left end is pressed and fixed; the inner wall of the arch-shaped groove is provided with a force measuring sensor, when the pressing force detected by the force measuring sensor reaches a set pressing force, the lifting plate descends to the lowest position, one end of the swinging rod, which is connected with the connecting rod, descends to the low end, so that the end of the swinging rod, which is connected with the trigger switch, is tilted to the high end, the trigger of the trigger switch is eliminated, the conveying belt is restarted and is continuously conveyed from the right side to the left side, the inner ring of the tubular part is polished by the polishing head when the lifting plate descends to the low end, the tubular part conveyed at the leftmost end in the conveying process of the conveying belt is sent out of the conveying belt, the sent tubular part automatically falls into the receiving hopper under the action of gravity, and dust generated by polishing enters the receiving hopper along with the tubular part and enters the waste hopper from the; the tubular piece clamped by the positioning clamp rubs against polishing abrasive paper, so that the bottom end of the tubular piece is polished, and the tubular piece on the right side of the clamped tubular piece is continuously conveyed from right to left along the conveying belt; after the clamped tubular piece is polished, the positioning cylinder drives the positioning clamp to reset, meanwhile, the lifting plate drives the polishing shaft to rise to the high end, the swinging rod drives the trigger switch to fall to the low end and align to the conveying cavity, and the process is repeated.
