In this process, the positions of the hinge rod 313 and the connecting column 314 are synchronously changed, at this time, the bidirectional stud 234 can be rotated to adjust the distance between the front and rear limiting frames 233, the moving block can also slide up and down along the chute plate 231, the moving block drives the front and rear limiting frames 233 to synchronously move through the bidirectional stud 234, when the moving block moves to a proper position, the moving block can be fixed on the chute plate 231 through the threaded clamping block 232, and further, the position of the limiting frames 233 can be adjusted, so that the limiting frames 233 can lock and fix the connecting columns 314 in different states.
Referring to fig. 1,2 and 5, the limiting rollers 311 are sleeved with laterally symmetrical limiting rings 331, the upper end of the workbench 1 is provided with a mounting groove 332, two sliding blocks which are longitudinally symmetrical are slidably mounted on the sides, which are close to the left and right inner walls of the mounting groove 332, of the workbench, and two bidirectional threaded columns 333 which are longitudinally symmetrical and are in threaded connection with the corresponding limiting rings 331 are rotatably mounted between the laterally opposite sliding blocks.
After the conveying pipeline 5 is placed between the front limiting roller 311 and the rear limiting roller 311, the conveying pipeline 5 is axially limited by the left limiting ring 331 and the right limiting ring 331, the limiting rings 331 do not interfere with the moving polishing of polishing pieces, under the cooperation of the left limiting ring 331 and the right limiting ring 331, the stability of the conveying pipeline 5 in the polishing process can be further improved, the influence on polishing effect and quality caused by the fact that the conveying pipeline 5 moves left and right along the limiting rollers 311 in the polishing process can be effectively avoided, so that the polishing uniformity of the inner wall is improved, in addition, when the length of the conveying pipeline 5 changes, the left limiting ring 331 and the right limiting ring 331 synchronously move reversely along the mounting groove 332, the distance between the left limiting ring 331 and the right limiting ring 331 is synchronously adjusted, and therefore limiting of the conveying pipeline 5 in the left and right directions with different lengths is achieved.
