The servo motor fixing seat 12 is fixed to the up-and-down moving slider 16 by two hexagonal screws, the servo motor fixing seat 12 is connected to the origin reset photoelectric switch bracket 34 by welding, the origin reset photoelectric switch 33 is connected to the bracket 34 by a thread, the servo motor fixing seat 12 is connected to the up-and-down moving sensing photoelectric switch bracket 26 by welding, and the up-and-down moving sensing photoelectric switch 29 is connected to the bracket 26 by a thread.

[0034] The present application has the function of automatically and quickly tightening the stop valve pipe fittings, and at the same time has a simple structure, saves costs, has minimal dependence on the environment, is easy to install and operate, and is convenient for personnel to operate.

[0035] The specific implementation process of the invention device in the production process is as follows: manually firstly gently twist the stop valve core 35 into the stop valve plastic pipe fitting 37 through the hexagonal clamping position 36 for two turns to bite two teeth, and then clamp the hexagonal clamping position 36 of the assembled stop valve pipe fitting 19 on the front and rear stop valve core limit plates 17, and place it at the front end of the right photoelectric switch 11. After the right photoelectric switch 11 detects the stop valve, the front and rear moving cylinder 25 moves to push the stop valve clamping block 24 forward to clamp the stop valve pipe fitting, and the front and rear moving slide column 23 ensures the stability of the front and rear movement and enhances the stability of the device. Then the left and right moving cylinder 5 moves to drive the left and right moving slide 21 to move to the left, and the stop valve clamping block 24 moves to the left together with the clamped stop valve pipe fitting 19. When the stop valve pipe fitting is sensed by the left photoelectric switch 9, the left and right moving cylinder 5 stops moving. At this time, the next stop valve pipe fitting can be placed manually in front of the right photoelectric switch 11, and the front and rear moving cylinder 25 drives the stop valve clamping block 24 to retreat. After the front and rear moving cylinder 25 returns to its original position, on the one hand, the left and right moving cylinder 5 moves to the right to the top point, and on the other hand, the up and down moving cylinder 2 descends and drives the servo motor fixing seat to move through the up and down moving slider 16 and the slide rail 14. When the up and down sensing photoelectric switch 29 senses the lower sensing iron sheet 28, the up and down moving cylinder 2 stops moving. At this time, the four cylindrical heads of the column head turntable 30 are just stuck in the stop valve plastic pipe fitting 37. Then the servo motor 13 runs and drives the column head turntable 30 to rotate through the coupling 32. When the servo motor 13 detects that the torque meets the tightening requirements, the servo motor 13 stops running, and the up and down moving cylinder 2 moves upward at the same time. When the up and down sensing photoelectric switch 29 senses the upper sensing iron sheet 27, the up and down moving cylinder 2 stops moving, and the servo motor 13 rotates according to the origin reset photoelectric switch 33 and the origin sensing iron sheet to restore to the same position of the four column heads at the beginning. Since the next stop valve pipe has been manually placed at the front end of the right inductive photoelectric switch 11, the servo motor will be reset at this time, and the forward and backward moving cylinder 25 will start to move forward for the second time, and the stop valve clamping block 24 will clamp the second stop valve pipe, and then the left and right moving cylinder 5 will start to move to the left for the second time. At this time, during the movement, on the one hand, the screwed stop valve pipe is pushed out from the left outlet along the unloading buffer inclined plate 6 through the pushing block 18, and on the other hand, the second stop valve pipe is brought to the front of the left photoelectric switch 9 by the left and right moving cylinder 5, and then the next tightening action is performed. The device is completed.
