Firstly, the pipe fitting is placed on a machine tool 01, the polishing mechanism is positioned on one side of the pipe fitting, then a traction rope 06 passes through the pipe fitting and is fixedly connected with a supporting plate 08, at the moment, a screw rod 05 rotates to drive a sliding seat 03 to slide on a sliding rail 02, so that the supporting plate 08 is pulled by the traction rope 06 to enable the polishing mechanism to integrally enter from one end of the pipe fitting, at the moment, as a tension spring 17 is arranged at the hinged position of a connecting rod I23 and a polishing strip 12, and a tension spring 17 (combined with fig. 3) is arranged at the hinged position of a ball supporting leg 11 and a sliding leg 13, the ball supporting leg 11 and the polishing strip 12 are gathered towards the central position of the same side, and the gathered side faces away from the pipe fitting in a square shape, therefore, when the traction rope 06 pulls, the ball supporting leg 11 and the polishing strip 12 can firstly enter into a pipeline from the gathered end, and the pipeline can squeeze the ball supporting leg 11 or the polishing strip 12, the sliding leg 13 slides inwards on the sliding barrel 14, the first connecting rod 23 rotates and contracts towards the middle on the sliding plate 24, so that the polishing strip 12 and the ball supporting leg 11 can conveniently enter the pipe fitting, after entering the pipe fitting, the polishing strip 12 and the ball supporting leg 11 can be attached to the pipe fitting in parallel due to the flat inside of the pipe fitting, the spring on the sliding plate 24 and the spring in the sliding barrel 14 can enable the ball supporting leg 11 and the polishing strip 12 to be attached to the pipe fitting in order to automatically enter the pipe fitting, and the motor 04 automatically adapts to the pipe fitting with different diameters, at the moment, the motor 04 starts to work, the motor 04 drives the universal shaft 18 to rotate when the flexible shaft 07 rotates through the output shaft, the universal shaft 18 rotates to drive the driving disc 32 to rotate, the first gear ring 33 and the second gear ring 35 are driven to rotate when the driving disc 32 rotates, because the directions of the first driving ring 34 and the first wedge block 27 on the driving block 36 are different, when the first gear ring 33 and the second gear ring 35 rotate, only the first gear ring 33 can push the first wedge block 27 to rotate or only the second gear ring 35 drives the driving block 36 to rotate;
for example, referring to fig. 7 and 8, when the driving disc 32 rotates clockwise, the driving disc 32 drives the first gear ring 33 and the second gear ring 35 to rotate clockwise, at this time, since the bevel of the first wedge 27 on the first driving ring 34 faces clockwise, the first gear ring 33 rotates and drives the first wedge 27 to rotate simultaneously, so as to drive the limiting seat 10 to rotate the first driving ring 34, at this time, since the first driving ring 34 is fixedly connected with the mounting seat 09, the mounting seat 09 also rotates, but the bevel of the driving block 36 faces anticlockwise, the second gear ring 35 drives the first wedge 27 on the driving block 36 to slide on the limiting seat 10, so as not to drive the driving block 36 to rotate, and similarly, when the driving disc 32 rotates anticlockwise, the second gear ring 35 drives the driving block 36 to rotate, and the first driving ring 34 does not rotate, i.e. the mounting seat 09 does not rotate and the second connecting rod 25 rotates;
when the mounting seat 09 rotates, the mounting seat 09 is mounted on the supporting plate 08 through the plurality of first fixing legs 15 and the first hinging legs 16, the first hinging legs 16 can horizontally rotate on the first fixing legs 15 and cannot vertically move due to the hinging direction of the first hinging legs 16 and the first fixing legs 15, the mounting seat 09 can rotate on the first hinging legs 16 through the limiting guide rail 31, the mounting seat 09 is supported through the first hinging legs 16, at the moment, the polishing strip 12 is driven to rotate when the mounting seat 09 rotates due to the fact that the polishing strip 12 is mounted on the mounting seat 09, so that the polishing strip 12 can circumferentially rotate when rotating, and the rotating track of the polishing strip 12 is circular, so that the polishing of the inner wall of a circular pipe fitting can be adapted;
referring to fig. 5, when the driving block 36 rotates, the driving block 36 drives the second connecting rod 25 to rotate, the second connecting rod 25 drives the movable frame 28 to rotate circumferentially, when the movable frame 28 rotates from the lowest direction or rotates from the highest direction, the movable frame 26 arranged horizontally slides upwards or downwards in the mounting seat 09, when the movable frame 28 rotates from the rightmost side to the left or rotates from the leftmost side to the right, the movable frame 26 arranged vertically slides leftwards and rightwards on the mounting seat 09, so that the second connecting rod 25 drives the movable frame 28 to rotate circumferentially and drives the two movable frames 26 to slide in two directions simultaneously, the sliding of the movable frame 26 arranged horizontally can polish the left side and the right side, and the sliding of the movable frame 26 arranged vertically can polish the upper side and the lower side, so that the polishing of square pipe fitting can be realized;
the internal turning is performed:
first, at the time of polishing, the polishing strip 12 for polishing can only contact the inner wall of the pipe and cannot be supported on the inner wall of the pipe by the polishing strip 12, so that the polishing function for the surface can be achieved, and therefore, the supporting mechanism is required to support the polishing strip 12 for polishing on the inner wall of the pipe;
under the traction of traction cable 06, because traction cable 06 is soft structure, can bend, drive simultaneously that flexible axle 07 also can bend, when polishing mechanism turns round in the pipeline inside, rotation of a backup pad 08 accessible articulated leg two 22 and fixed leg two 21 is bent with mount pad 09 relatively, another backup pad 08 realizes bending through fixed leg one 15 and articulated leg one 16, consequently can realize supporting mount pad 09 and make it polish in the same time to can adapt to most pipeline bending angle, thereby realize can be at the inside function of turning round of pipe fitting, after accomplishing polishing with traction cable 06 take off can.
