The working principle is as follows: the rotating turntable 46 is rotated to enable the anti-drop piece 4 to work, the rotating turntable 46, namely the main shaft 45 fixedly connected with the center of the turntable 46, rotates, the sliding curved rod 44 on the main shaft 45 rotates, due to the limit of the curved arc groove 41 to the transmission rod 42 on the anti-drop piece 43, when the sliding curved rod 44 rotates, the anti-drop piece 43 slidingly connected with the sliding curved rod 44 moves outwards while rotating synchronously with the sliding curved rod 44, so that the outer side of the anti-drop piece 43 extends out of the upper end face of the fixed roller 13, when the anti-drop piece 43 extends out of and is clamped at the clamping position of the upper end face of the grinding roller 14, the fixed roller 13 is fixed and difficult to rotate, so that the expansion piece 2 in the fixed roller 13 can better expand the FRP pipe, after the expansion piece 2 works, the area of the anti-drop piece 43 between the fixed roller 13 and the grinding roller 14 is adjusted, at the fixing of the fixed roller 13 is released, so that the fixed roller 13 rotates to drive the FRP pipe to rotate and grind, the glass fiber reinforced plastic pipeline can be prevented from popping out of the fixed roller 13 when the glass fiber reinforced plastic pipeline is polished when the expansion piece 2 fails, so that the glass fiber reinforced plastic pipeline is safer and more reliable;
the device is externally connected with a power supply, a glass steel pipeline penetrates into a proper position on a fixed roller 13, a motor 11 is started, an output shaft of the motor 11 drives a transmission shaft 12 to rotate, at the moment, a swelling part 2 works, the transmission shaft 12 rotates, namely, a cross-shaped transmission block 22 fixedly connected above the transmission shaft 12 rotates, so that a butting rod 23 is squeezed, the butting rod 23 is squeezed to move outwards, a hard arc piece 24 fixedly connected to the outer side of the butting rod 23 moves outwards, so that the inner wall of the glass steel pipeline is swelled, a sucker 25 provides larger adhesive force for the inner wall of the glass steel pipeline, the glass steel pipeline can be swelled more firmly, and the inner swelling outer side polishing mode is adopted, so that the outer side of the glass steel pipeline can be polished;
when the expansion piece 2 works, the abutting rod 23 moves outwards to drive the reinforcing piece 3 to work, the sealing piston sleeve 32 fixedly sleeved on the abutting rod 23 moves outwards, sealing liquid in the water channel 34 is absorbed by the sponge block 33, the sponge block 33 is extruded when the sealing piston sleeve 32 moves outwards, the sponge block 33 is extruded to separate out the sealing liquid, the separated sealing liquid enters the inner wall of the sucking disc 25 through the Y-shaped hole 35, so that air in the sucking disc 25 is more thoroughly discharged, the adhesive force of the sucking disc 25 to the inner wall of the glass steel pipeline is increased, the hard-to-hard contact generated when the inner wall of the glass steel pipeline is expanded is avoided by adopting the mode, the damage generated when the glass steel pipeline is fixed is reduced, when the expansion piece 2 completes the expansion of the inner wall of the glass steel pipeline, the sealing piston sleeve 32 just moves to and blocks the Y-shaped hole 35, and the air is prevented from entering the sucking disc 25 through the Y-shaped hole 35 to reduce the expansion force of the sucking disc 25 to the glass steel pipeline;
when the motor 11 rotates, the expansion piece 2 expands and fixes the FRP pipe, the anti-release piece 4 is adjusted to remove the fixation of the expansion piece 2, at the moment, the motor 11 continues to rotate to drive the FRP pipe on the fixing roller 13 to rotate, the outer side wall of the FRP pipe is contacted with the polishing roller 14 so as to polish the outer side wall of the FRP pipe, and the polishing roller 14 is in rotary connection so as to facilitate the polishing roller 14 to rotate when polishing the outer side wall of the FRP pipe, thereby facilitating better polishing;
when the outer side wall of the glass fiber reinforced plastic pipeline is polished, the motor 11 works to drive the transmission shaft 12 to rotate, the inclined ring groove 53 on the transmission shaft 12 limits the L-shaped rod 52, so that the transmission shaft 12 rotates and the L-shaped rod 52 moves up and down at the same time, namely, the rough polishing block 55 fixedly connected to the L-shaped rod 52 moves up and down, so that the bottom side wall of the glass fiber reinforced plastic pipeline is continuously polished, and the polishing effect and the polishing range are increased; the rough grinding block 55 continuously moves up and down to intermittently grind the bottom side wall of the glass fiber reinforced plastic pipeline, so that the condition that the quality and the normal operation of the device are influenced due to a large amount of heat generated by the friction contact of the rough grinding block 55 and the grinding surface of the bottom side wall of the glass fiber reinforced plastic pipeline can be prevented;
when the FRP pipe is polished, scraps generated by polishing fall down, the L-shaped rod 52 moves up and down when the pipe bottom polishing piece 5 works, so that the hollow transmission ring 63 is extruded and moves up and down, the T-shaped pressing block 64 on the hollow transmission ring 63 moves up and down so that the elastic bag 65 is extruded, the elastic bag 65 is pressed, so that air is blown out to blow the scraps generated by polishing the FRP pipe to the inlet side of the channel 61, so that the scraps enter the scraps bin 62 through the channel 61, and the scraps are collected;
when the grinding roller 14 rotates, the auxiliary member 7 works, the grinding roller 14 rotates, namely, the rotating shaft 71 fixedly connected with the bottom of the grinding roller 14 rotates, and the concave rod 72 and the material guiding sheet 73 on the rotating shaft 71 are designed to prevent the passage 61 from being blocked by a large amount of attached waste chips.
