The pipe placing structure conveys the steel pipe to be turned to the pipe conveying structure, the pipe conveying structure conveys the steel pipe to the opposite-ejecting structure, and the turning tool assembly turns the excircle of the steel pipe clamped and rotated by the opposite-ejecting structure to complete the excircle turning treatment of the steel pipe at one time. The process is repeated in this way, and can continuously and rapidly turn the outer circle of a large amount of steel pipes, so that the steel pipes can obtain smooth surfaces and good concentricity of the inner circle and the outer circle.
Preferably, the opposite-vertex structure comprises a driving box with a rotating main shaft and movable tailstock frames arranged at intervals, the center of each tailstock frame is coaxial with the rotating main shaft, and a pair of coaxial opposite-vertex points are arranged on the centers of the rotating main shaft and the tailstock frames.
The movable tailstock can be close to or far away from the rotating main shaft through a movable structure consisting of a linear guide rail, a ball screw, a motor and the like, so that a pair of centers loaded on the movable tailstock are coaxially close to or far away from the rotating main shaft, the movable tailstock is suitable for clamping and releasing seamless steel pipes with different sizes and lengths, and the centers abut against the two ends of the steel pipes and then the rotating main shaft drives the steel pipes to rotate.
Preferably, the turning tool assembly comprises an XY workbench, a tool apron arranged on the XY workbench, and a turning tool arranged on the tool apron.
The XY workbench is a numerical control workbench, a turning tool can be controlled by a CNC numerical control program to move, after the opposite-vertex structure clamps and enables the steel pipe to rotate, the turning tool is controlled by a preset and debugged program to translate from one end of the steel pipe to the other end of the steel pipe by determined feed amount to finish the turning action of one steel pipe, after the steel pipe is released, the pipe conveying structure conveys the other steel pipe to be processed to the opposite-vertex structure, and the turning tool reversely moves from the position where the last turning action is finished to the position where the turning action is started to finish the turning action of the next steel pipe. The adjustable thickness of blade holder and with the distance of steel pipe, guarantee that the position of lathe tool is fit for various steel pipes of thickness and variation in size.
Preferably, the pipe placing structure comprises a mounting bottom plate connected with the top surface of the rack, a pipe placing frame for loading steel pipes, a pipe placing bottom plate for bearing the pipe placing frame, and an inclined support plate for connecting the mounting bottom plate and the pipe placing bottom plate.
The pipe placing bottom plate is inclined downwards along the direction facing the rack, so that a steel pipe loaded on the pipe placing frame on the pipe placing bottom plate naturally has a tendency of toppling towards the opposite structure; the dumped steel pipes fall onto the pipe conveying structure and are conveyed to the opposite-top structure by the pipe conveying structure.
Preferably, the pipe placing frame comprises a bottom plate, baffle plates arranged on two sides of the bottom plate in the width direction, and an L-shaped cover plate with adjustable height and arranged at the tail end of the lower side of each baffle plate; l shape cover plate's both sides limit is opened there is the adjustment tank, the correspondence of baffle be equipped with on the position of adjustment tank and adjust pole and lock nut.
Highly setting up to the diameter that is slightly higher than the arbitrary big or small steel pipe in the certain limit with L shape cover plate for put the pipe support and can hold the steel pipe of multiple size, and combine the effect of baffle, make the steel pipe can be carried forward by a root, the steel pipe can not appear jumping out and put the pipe support outer or the condition that is being sent out is being overlapped to two above steel pipes simultaneously.
