Detailed Description
The principles and features of the present invention will be described with reference to the drawings, which are provided for illustration purposes only and are not intended to limit the scope of the present invention.
As shown in fig. 1, fig. 2 and fig. 3, the multi-station sawing threading device of the present embodiment includes a sawing machine 17 and a threading machine 18, and is characterized by including a support frame, a toggle mechanism and a driving portion; the supporting frame comprises two parallel supporting rods 1, rollers 2 used for conveying pipes 14 are connected in the supporting rods 1, and the rollers 2 are rotatably connected to the supporting rods 1;
the shifting mechanism comprises a horizontal frame 3, a plurality of shifting rods 4 and two groups of same four-bar mechanisms; the horizontal frame 3 is positioned below the support frame, the deflector rods 4 are connected to the horizontal frame 3 and can vertically extend upwards to cross the surface of the support frame, a preset distance is reserved between every two adjacent deflector rods 4, two connecting pieces 31 are arranged at the bottom end of the horizontal frame 3, and a four-bar mechanism is arranged below the horizontal frame 3; the four-bar mechanism comprises a rack I91, a rack II 92, a crank 5, a connecting rod 6 and a rocker 7, wherein one end of the crank 5 is hinged to the rack I91, the other end of the crank is hinged to one end of the connecting rod 6, the other end of the connecting rod 6 is hinged to one end of the rocker 7, the other end of the rocker 7 is hinged to the rack II 92, a supporting rod 8 is fixedly arranged in the middle of the connecting rod 6 in an upward extending mode, and the top of the supporting rod 8 is hinged to a connecting piece 31;
the driving part is connected with the crank 5 and is used for driving the cranks 5 of the two four-bar linkage mechanisms to synchronously rotate; when the crank 5 is driven by the driving part to rotate to the horizontal position, the top of the deflector rod 4 and the support frame are at the same horizontal height; the saw-cutting machine 17 and the threading machine 18 are arranged outside the support frame in a position corresponding to the position of the roller 2.
As shown in fig. 1 and 4, the driving part comprises two gears 10, a chain 11 wound around the outer sides of the two gears 10, and a crank 12 fixedly connected to one gear 10; a rotating shaft 15 penetrates through the rack I91, and the center of the gear 10 and one end of the crank 5 are fixedly connected to the rotating shaft 15. Further, a bearing 16 is fixedly sleeved in the rack I91, the inner ring of the bearing 16 is fixedly sleeved with the rotating shaft 15, and the gear 10 and the crank 5 are arranged on two sides of the bearing 16. The crank 12 is rotated to drive the two groups of four-bar linkage mechanisms to synchronously move through the gear 10 and the chain 11, so that the driving lever 4 on the horizontal frame 3 is driven to move, and the driving lever 4 rotates along an approximately circular track. In this embodiment, the shifting levers 4 are spaced apart from each other by a predetermined distance and are arranged at equal intervals, the cranks 12 are rotated, one shifting lever 4 shifts the pipe 14 forward to a certain position, the cranks 12 are continuously rotated, the adjacent shifting levers 4 can continuously shift the pipe 14 forward, and the pipe 14 can be continuously conveyed forward repeatedly.
Further, the present embodiment further comprises a hopper 13, the hopper 13 has an inclined bearing surface, the lower part of the hopper 13 has an opening for allowing only one pipe to pass through, and the hopper 13 is located above the supporting frame and has a gap with the supporting frame for allowing only one pipe to pass through. During the use, in hoisting the pipe fitting to hopper 13 through the crane, the pipe fitting can slide down automatically on the support frame.
In this embodiment, the position of roller 2 matches with the track of stirring of driving lever 4, and driving lever 4 stirs the pipe fitting, and the pipe fitting slides on roller 2 promptly. The operator can easily pull the pipe to the saw cutter 17 with the roller 2 for the cutting operation. After cutting, the pipe is returned to the roller 2, the crank 12 is rotated again, the pipe is shifted to the roller 2 corresponding to the threading machine 18, and an operator performs threading work on the pipe. After the threading is completed, the pipe fitting is pushed backwards, so that the pipe fitting slides backwards along the rollers 2 and falls down the support frame for stacking. So, need not carry the artifical mantle fiber that saw cuts that can accomplish the pipe fitting to the pipe fitting.
