Working principle: when welding and splicing the high-density polyethylene pipe, the positioning driving mechanism is started, the two sections of high-density polyethylene pipe to be processed are respectively placed in the lower arc-shaped seats on the base at the corresponding positions by the staff, then the staff controls the two rod bodies of the electric push rod on the processing table to shrink through the control equipment, the rod bodies of the electric push rod two shrink and drive the top mounting seat on the electric push rod two to synchronously move downwards, the top mounting seat synchronously moves downwards while driving the upper arc-shaped seat at the bottom of the top mounting seat to synchronously move downwards, the upper arc-shaped seat at the bottom of the top mounting seat moves downwards and is matched with the lower arc-shaped seat on the base, Thus completing the positioning and fixing treatment of the pipe fitting, when the pipe fitting with fixed positioning between the lower arc-shaped seat and the upper arc-shaped seat is required to be driven to rotate, a worker controls the driving motor on the top mounting seat to start through the control equipment, the rotating shaft on the driving motor drives the cylindrical gear rod I on the top mounting seat to synchronously rotate while the driving motor starts, the cylindrical gear rod I drives the cylindrical gear rod II at the bottom of the top mounting seat to synchronously rotate through the toothed belt while rotating, the cylindrical gear rod II drives the cushion rollers at the two ends of the cylindrical gear rod II to synchronously rotate while rotating, because the surfaces of the cushion rollers are contacted with the surfaces of the pipe fitting, The soft cushion roller is matched with the ball in the upper arc-shaped seat through the lower arc-shaped seat when rotating, so that the pipe fitting pipe between the lower arc-shaped seat and the upper arc-shaped seat is driven to rotate, and the positioning driving treatment of the pipe fitting is completed; Then the push-pull moving mechanism is started, a worker starts the first electric push rod at the bottom of the processing table through the control equipment, the rod body on the first electric push rod is contracted after the start, the upper rod body of the first electric push rod is contracted, the side plate on the first electric push rod is driven to synchronously move towards the processing table, in the moving process of the side plate, the end part of the pipe fitting pipe positioned and fixed between the lower arc-shaped seat and the upper arc-shaped seat enters the limit clamping groove of the rotating seat, and simultaneously, the inner wall of the pipe fitting pipe is synchronously fixed through the limit fixing seat on the rotating seat, so when the worker starts the first electric push rod on the processing table through the control equipment, The rod body of the first electric push rod pushes out or contracts and simultaneously drives the side plate to synchronously move, and the side plate synchronously moves and simultaneously drives the pipe fitting pipe on the rotating seat to synchronously push and pull so as to finish the push and pull movement treatment of the pipe fitting pipe; Then the interface detection mechanism is started, a worker manually pulls the mounting ring seat, the mounting ring seat rotates and drives the connecting seat on the mounting ring seat to synchronously rotate in the side mounting seat, when the mounting ring seat rotates and is regulated to be vertical to the top mounting seat, the worker controls the push-pull moving mechanism to start through the control equipment, so that the side plate on the push-pull moving mechanism pushes the pipe fitting pipe between the lower arc seat and the upper arc seat to synchronously move, the splicing end of the pipe fitting pipe is positioned in the mounting ring seat, then the worker regulates the marker pen in the mounting sleeve, the pen end of the marker pen is contacted with the outer wall of the pipe fitting pipe, and simultaneously, the exposed marker color ring on the mounting sleeve is ensured to be positioned at the position of the same marker color, Finally, a worker controls the positioning driving mechanism to start through the control equipment, so that the pipe fitting pipe between the lower arc-shaped seat and the upper arc-shaped seat rotates, the rotating seat on the side plate at the end part position is synchronously driven to synchronously rotate while the pipe fitting pipe rotates, the marking pen in the mounting ring seat performs line drawing detection on the splicing position of the pipe fitting pipe while the pipe fitting pipe rotates, the detection processing on the splicing position of the pipe fitting pipe is finished, after the pipe fitting pipe rotates for a plurality of circles, if a certain position at the splicing position of the pipe fitting pipe is broken, the situation that the pipe fitting pipe at the position is sunken is indicated, and if the pipe fitting pipe is sunken after the rotation is finished, The color of the mark color ring mark on the marking pen in the mounting sleeve is changed, so that the fact that a certain convex condition exists at the splicing position of the pipe fitting pipe is indicated;
