[0039] See also Figure 1-6The present invention provides an opening and closing short steel bar positioning mechanism, comprising a bottom plate 1, a positioning plate 2 is provided on the bottom plate 1, a first through hole 3 is provided on the positioning plate 2, a rotating plate 4 is provided in the first through hole 3, the rotating plate 4 is rotatably connected to the first slide groove 5 of the positioning plate 2, and clamping parts 6 are respectively provided on both sides of the rotating plate 4, the clamping parts 6 are located at the edge of the second through hole 7 on the rotating plate 4, the clamping parts 6 include two symmetrically arranged clamping units 61, the clamping units 61 include A mounting seat 611, a first drive motor 612, a slide rod 613 and a clamping block 614, wherein the mounting seat 611 is connected to the rotating plate 4, the slide rod 613 is slidably connected in the mounting seat 611, the clamping block 614 is connected to one end of the slide rod 613, and a plurality of tooth grooves are provided on the slide rod 613, which mesh with the first gear 8, and the first gear 8 is connected to the drive shaft of the first drive motor 612, and the first drive motor 612 is mounted on the mounting seat 611.

[0040] The clamping block 614 is provided with a diameter-reducing clamping groove 6141, which can adapt to the fixation of steel bars of different sizes.

[0041] The mounting base 611 is provided with a second chute 615, and the slide rod 613 is slidably connected to the second chute 615. The mounting base 611 is provided with at least one limiting groove 6111, which is connected to the second chute 615. The slide rod 613 is provided with a limiting block 6131 that matches the limiting groove 615. The mounting base is detachably connected to the rotating plate via screws. The limiting block cooperates with the limiting groove to prevent the slide rod from rotating, so that the slide rod can only move in a straight line, thereby preventing the clamping block from not contacting the rebar and causing the clamping block to fail to clamp the rebar.

[0042] The mounting seat 611 is provided with a third through hole 6112, which is connected to the second sliding groove 615, and the first gear 8 is located in the third through hole 6112. This facilitates the first gear to engage with the sliding rod.

[0043] The positioning plate 2 includes an upper positioning plate 21 and a lower positioning plate 22. One end of the upper positioning plate 21 is hinged to the lower positioning plate 22, and the other end of the upper positioning plate 21 is a free end. This makes it easy to open the upper positioning plate.

[0044] At least one second drive motor 9 is mounted on the lower positioning plate 22. A second gear 10 is connected to the drive rod of the second drive motor 9. The second gear 10 meshes with the second tooth groove on the rotating plate 4. The second drive motor drives the second gear to rotate, which in turn drives the rotating plate to rotate the steel bar, thereby facilitating welding, achieving automated adjustment, and reducing the difficulty of welding operations.

[0045] The two ends of the bottom of the lower positioning plate 22 are respectively provided with sliders 11, and the sliders 11 are slidably connected to the slide rails 12 on the bottom plate 1. In this way, the position of the positioning plate can be adjusted to facilitate welding between steel bars of different lengths.

[0046] A plurality of rotating shafts 13 are provided on both sides of the rotating plate 4. The rotating shafts 13 are rotatably connected to guide wheels 14, which contact the edges of the first through holes 3. This serves to limit the rotation and prevent the rotating plate from being eccentric during rotation.

[0047] The rotating plate 4 comprises an upper rotating plate 41 and a lower rotating plate 42, both of which have identical structures. This facilitates the removal and placement of rebar. A magnet is located within the upper positioning plate to hold the upper rotating plate in place. However, when the second drive motor is activated, the lower rotating plate drives the upper rotating plate to move.

[0048] Working principle: The steel bar is passed through the second through hole, and the two clamping units on both sides of the rotating plate move toward each other at the same time to clamp the steel bar and start welding. Then the second drive motor drives the second gear to rotate, and the second gear drives the rotating plate to rotate, so that the steel bar can be rotated to a certain angle to weld the unwelded areas. Finally, the rotating plate is restored to its original position, and the clamping unit is also restored to its original position. The steel bar is then pulled out. In places where there is insufficient space, the upper positioning plate can be opened so that the steel bar can be taken out from above. The present invention achieves the purpose of fixing the steel bar and simplifying the steel bar fixing operation by arranging a clamping component on the rotating plate. Specifically, the steel bar is passed through the second through hole, and the first drive motor drives the first gear to rotate. The first gear then drives the slide bar to move toward the steel bar in the mounting seat, so that the clamping block is against the surface of the steel bar. The clamping block is provided with a variable diameter clamping groove, which can adapt to steel bars of different sizes, realize automatic clamping, avoid direct contact between the operator and the steel bar, avoid burns to the operator, and improve safety. By arranging a second drive motor and a second gear on the lower positioning plate, the second drive motor drives the second gear to rotate, and then drives the rotating plate to rotate, so that the steel bar rotates and welding is performed, realizing automatic adjustment and reducing the difficulty of operation.

[0049] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
