The bolt pushing and buffering device (5) comprises a bolt pushing device (51) and a workpiece conveying mechanism (52). The point welding device (6) comprises a conical head or sealing plate pushing device (61), a point welding robot (62), and a lifting and translating device (63). The conical head or sealing plate sorting device (7) comprises a conical head or sealing plate sorting robot (71) and a marking machine (72). The bolt sorting robot (41) is used for sorting bolts and putting the bolts into the bolt pushing device (51). The conical head or sealing plate sorting robot (71) is used for sorting conical heads or sealing plates and putting the sorted conical heads or sealing plates on the marking machine (72). The marking machine (72) marks the conical heads or sealing plates. After marking, the conical heads or sealing plates are put on the conical head or sealing plate pushing device (61). The team point welding device detects whether the workpiece to be processed is cleaned and transported to the position. After being transported to the position, the workpiece to be processed is moved to a bolt mounting station by the lifting and translating device (63). The two end bolts are pushed into the workpiece to be processed by the bolt pushing device (51). After the bolts are pushed in, the workpiece to be processed is moved to a conical head or sealing plate mounting station by the workpiece conveying mechanism (52). The two end conical heads or sealing plates are pushed into the workpiece to be processed and fixed by the conical head or sealing plate pushing device (61). After the conical heads or sealing plates are mounted, the point welding robot (62) starts to work. The workpiece to be processed is point welded according to the pre-set point welding position and quantity. After point welding, the workpiece to be processed is transported to a girth welding device (8) by the lifting and translating device (63).

8. The multi-specification rod co-linear production apparatus of claim 7, wherein, After the two end bolts are pushed into the workpiece to be processed by the bolt pushing device (51), the bolt sorting robot (41) continues to sort bolts and put the bolts into the bolt pushing device (51). After the two end conical heads or sealing plates are pushed into the workpiece to be processed and fixed by the conical head or sealing plate pushing device (61), the conical head or sealing plate sorting robot (71) continues to sort conical heads or sealing plates and put the sorted conical heads or sealing plates on the marking machine (72). The marking machine (72) continues to mark the conical heads or sealing plates and put the marked conical heads or sealing plates on the conical head or sealing plate pushing device (61).

9. The apparatus of claim 1 wherein, The ring seam welding device (8) comprises a lifting and translating device (81), a jacking device (82), a clamping device (83), and a ring seam welding robot (84). The lifting and translating device (81) moves the to-be-processed rod to a ring seam welding station. The jacking device (82) adjusts the center positions of the to-be-processed rod and the clamping device (83) to be centered. The clamping device (83) clamps and fixes the to-be-processed rod and drives the to-be-processed rod to start rotating. The ring seam welding robot (84) welds the weld according to the tracking position of the weld. After welding is completed, the to-be-processed rod is transported to a discharging area by the lifting and translating device (81).

10. The multi-specification rod co-linear production apparatus of claim 1, wherein, The total control system queries the discharging method of the to-be-processed rod from a production task sheet, sends corresponding cutting process instructions to the cutting device (2) to execute cutting on the to-be-processed rod, and sends a start command and a control mode to the team point welding device and the ring seam welding device (8). The team point welding device and the ring seam welding device (8) perform point welding and ring seam welding under the control of the total control system.
