[0032] like Figure 2 and Figure 7 , also includes a support assembly 17, the support assembly 17 includes a sliding rod 171, a sliding plate 172, a seat 173, a guide roller 174 and a wheel 175, a slide groove is symmetrically opened horizontally at the lower right side of the machine tool 1, a sliding rod 171 is slidably arranged in the slide groove, a sliding plate 172 is arranged between the two sliding rods 171, the top of the sliding plate 172 is symmetrically connected with a seat 173 by bolts, a guide roller 174 is rotatably arranged between the two seat bodies 173, the guide roller 174 is flush with the guide roller 14, and a wheel 175 is symmetrically rotatably arranged at the bottom of the sliding plate 172.

[0033] When it is necessary to polish the outside of the plastic composite connection elbow port, push the plastic composite pipe to the left. When the plastic composite connection elbow port contacts the movable plate 153, it plays a positioning role. Then the staff pulls the sliding shaft 157 forward, and the sliding shaft 157 squeezes the inclined groove 154 of the movable plate 153, and then the movable plate 153 moves downward and no longer contacts the plastic composite connection elbow port. The movable plate 153 moves downward, the third elastic member 159 is compressed, and the pull rope 164 is relaxed, and then the first elastic member 7 drives the sliding rod 4 to move toward the plastic composite connection elbow position, and the four transmission rollers 6 contact the side wall of the plastic composite connection elbow to clamp and position the side wall of the plastic composite connection elbow. The movement of the transmission roller 6 drives the rotating rod and the dual-axis motor 83 to move forward synchronously through the slide plate 81. At this time, the staff rotates the rotating plate 9. After the rotating plate 9 rotates 90°, the semi-arc groove of the rotating plate 9 is engaged with the sliding shaft 157, thereby completing the fixing of the fixed plate 163 is positioned to prevent the movement of the fixed plate 163. At the same time, the staff rotates the rocker 104, and the rocker 104 drives the screw 103 to rotate, so that the grinding assembly 13 is located at the plastic composite connecting pipe bend port position, and then moves the sliding frame 12 to the right, and the sliding frame 12 drives the grinding assembly 13 to be located on the inner side of the plastic composite connecting pipe bend port, and then rotates the rocker 104 in the opposite direction to move the grinding assembly 13 up, and the grinding roller 132 contacts the top of the inner wall of the plastic composite connecting pipe bend port. At this time, the staff controls the dual-axis motor 83 to work, and the dual-axis motor 83 is driven by the pulley and the flat belt, and the drive roller 6 drives the plastic composite connecting pipe bend port to rotate. At the same time, the drive motor 133 is controlled to work, and the drive motor 133 drives the grinding roller 132 to rotate in the opposite direction of the plastic composite connecting pipe bend through the bevel gear 134, and the grinding roller 132 quickly grinds the inner side of the plastic composite connecting pipe bend port position. If the outer wall of the straight plastic composite pipe orifice needs to be polished, the staff first pulls the sliding plate 172 to the right, and the sliding plate 172 drives the sliding rod 171 to slide out to the right. Then the guide roller 14 and the guide roller 174 are used to support the steel skeleton plastic composite pipe to prevent the pipe from tilting during polishing, and then repeat the previous clamping and fixing operation. The staff then directly adjusts the adjustment component 10 and the polishing component 13 so that the polishing roller 132 of the polishing component 13 contacts the outer wall of the composite pipe orifice, and repeats the previous polishing action, which can quickly polish the outer wall of the composite pipe orifice. The device has a simple structure and can polish and polish the outer surface of the large-diameter composite pipe orifice and the inner surface of the curved pipe, which is conducive to the subsequent installation and connection of the composite pipe and the curved pipe.

[0035] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
