This will use a stainless steel pipe inner surface polishing equipment. However, it cannot guarantee that the steel pipe can be polished in all directions of 360 degrees during polishing. Therefore, a stainless steel pipe surface polishing equipment is proposed.

The reciprocating screw rod 901 is dynamically connected, and a slider B903 is provided on the surface of the slider B903. A scraper 904 is fixedly connected to the surface of the slider B903. The bottom of the scraper 904 contacts the inner wall of the processing box 1. Two dust inlets 10 are symmetrically provided on the inner wall of the processing box 1. An extension rod 807 is fixedly connected to one side of the gear ring 801. A ball 808 is fixedly connected to the other end of the extension rod 807. An annular groove is provided on the inner side of the processing box 1. The ball 808 is slidably connected to the groove wall of the annular groove. The ball 808 rolls in the annular groove, thereby limiting the gear ring 801, so that the gear ring 801 has better stability during rotation. Two supporting legs 2 are fixedly connected to the bottom of the processing box 1, and a slide rail is fixedly connected to the adjacent side of the supporting leg 2. A collection box 4 is slidably connected to the slide rail. A handle 5 is fixedly connected to the outer wall of the collection box 4. The collection box 4 is used to collect debris generated during polishing. The collection box 4 can be conveniently taken out by the handle 5.

[0027] Furthermore, the gear 806 is provided to drive the gear ring 801 to rotate, and the gear ring 801 drives the ball 808 to roll in the annular groove through the extension rod 807 to ensure the stability of the gear ring 801 during the rotation process. The positioning fixture 803 is provided to fix the BA tube body 6, thereby driving the BA tube body 6 to rotate, so that it is turned over during the polishing process, thereby polishing the circumferential surface of the BA tube body 6, effectively improving the polishing efficiency of the BA tube body 6.

[0028] When the high-efficiency BA tube surface polishing device of the utility model is used, one end of the BA tube body 6 is inserted into the inner side of the positioning sleeve 802 and extended from the other side of the processing box 1, and the outer surface of the BA tube body 6 is fixed by the positioning fixture 803 inside the positioning sleeve 802; then, by starting the motor A701, the output end of the motor A701 drives the threaded rod 702 to rotate, and the rotating threaded rod 702 drives the slider A703 to slide in the slide hole, and the polishing wheel 706 moves with the slider A703 to adjust the position required for polishing below, and when the polishing wheel 706 is adjusted to the upper side of the polishing position of the BA tube body 6, the electric cylinder 704 is started to make the electric cylinder 704 The telescopic end drives the polishing wheel 706 to move downward until the arc groove 7011 at the bottom of the dust cover 7010 fits with the outer surface of the BA tube body 6. As the dust cover 7010 continues to move downward, the extrusion rod 709 at the top of the dust cover 7010 presses the spring 708 upward, so that the bottom of the polishing wheel 706 fits with the outer surface of the BA tube body 6, ensuring the stability of the local polishing of the BA tube body 6. Then, the motor B705 is started, and the output shaft of the motor B705 drives the polishing wheel 706 to rotate. The rotating polishing wheel 706 is used to polish the outer surface of the BA tube body 6. The waste chips generated during polishing are blocked by the inner side of the dust cover 7010, thereby preventing the waste chips from spreading to the surroundings. When different positions of the outer surface of the BA tube body 6 need to be polished, it is only necessary to start the motor C804, so that the output end of the motor C804 drives the rotating rod 805 to rotate, and the other end of the rotating rod 805 drives the gear 806 to rotate, and the gear ring 801 drives the ball 808 to roll in the annular groove through the extension rod 807. At the same time, the rotating gear 806 drives the gear ring 801 to rotate. Since the positioning sleeve 802 is fixedly connected to the gear ring 801, the positioning sleeve 802 rotates with the gear ring 801. Since the positioning fixture 803 has fixed the BA tube body 6, the BA tube body 6 rotates with the positioning sleeve 802, so that it turns over during the polishing process. Thereby, the circumferential surface of the BA tube body 6 is polished. During the rotation of the rotating rod 805, the belt between the pulley A and the pulley B is transmitted, and the rotating rod 805 drives the reciprocating screw 901 to rotate in the same direction. Since the limit rod 902 applies a limiting effect on the slider, the reciprocating screw 901 is used to drive the slider to reciprocate left and right. At the same time, the scraper 904 follows the slider to reciprocate left and right on the inner wall of the processing box 1. The waste chips generated during polishing pass through the dust inlet 10 under the action of the scraper 904 and fall into the collection box 4 to complete collection; by pulling the handle 5 outward, the collection box 4 is taken out from between the support legs 2, and the waste chips in the collection box 4 can be centrally processed.
