The motor module is fixedly installed on the base. The fixture is designed based on the shape of the bent part, and the spring buffer provides workpiece protection and automatic positioning, resulting in a simple and convenient structure.

[0004] However, this existing technology cannot adjust or change the specifications of subsequent bending of the workpiece, which means its practicality needs to be improved. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] The present invention will be further described in detail below with reference to embodiments:

[0025] Example 1

[0026] like Figure 1-4 As shown, this utility model provides an automatic positioning bending fixture, including a receiving platform 1, a bending adjustment seat 6 is provided on the upper surface of the receiving platform 1, a pressure member 2 is movably inserted into the inner wall of the bending adjustment seat 6, and a lifting drive assembly is provided at the top of the pressure member 2.

[0027] The upper surface of the receiving platform 1 is provided with a T-slot 8. The inner wall of the T-slot 8 is rotatably connected with a bidirectional threaded rod 18. The outer wall of the bidirectional threaded rod 18 is threadedly connected with a positioning post 14. The bending adjustment seat 6 includes a slider 9. The slider 9 is fixedly connected to the top of the positioning post 14, and the positioning post 14 is slidably connected to the inner wall of the T-slot 8.

[0028] The top of the slider 9 is provided with a roller mounting groove 17. The inner wall of the roller mounting groove 17 is movably connected to a limiting roller 10. One end of the limiting roller 10 is rotatably connected to a positioning post 14. The outer wall of the positioning post 14 is fitted with a collar frame 15. The inner wall of the collar frame 15 near the bottom is fitted with a connecting post. The connecting post is fixedly connected to the side of the slider 9.

[0029] The outer wall of the positioning post 14 is movably sleeved with a limiting horizontal plate 11. A transverse limiting groove 13 is provided on the side of the limiting horizontal plate 11, and the inner wall of the transverse limiting groove 13 is slidably connected to the outer wall of the positioning post 14.

[0030] Example 2

[0031] like Figure 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, the outer wall of the positioning post 14 near one end is provided with a threaded hole, and the inner wall of the threaded hole is threadedly connected to a limit threaded rod 16.

[0032] One end of the bidirectional threaded rod 18 is fixedly connected to a drive motor 12.

[0033] The lifting drive assembly includes a telescopic rod 4, the bottom end of which is fixedly connected to a connector 3 via a socket, the bottom end of which is fixedly connected to the top of the pressure-applying component 2, and the top end of the telescopic rod 4 is fixedly connected to a support frame 5.

[0034] The receiving platform 1 has a scale strip 7 fixedly connected to its side near the top.

[0035] The working principle of this automatic positioning bending fixture will be explained in detail below.

[0036] like Figure 1-4 As shown, when in use, the worker places the workpiece on the bending adjustment seat 6. At this time, the symmetrically distributed limiting rollers 10 lift the workpiece. Then, the telescopic rod 4 is activated, which pushes the pressure component 2 to move downward. The bottom end of the pressure component 2 applies pressure to the surface of the workpiece. As the pressure component 2 continues to move downward, the workpiece is gradually bent to form a V-shape.

[0037] When it is necessary to change the bending angle of the workpiece, the drive motor 12 is started to drive the bidirectional threaded rod 18 to rotate. When the bidirectional threaded rod 18 rotates, it will use its bidirectional thread to drive the two symmetrical positioning pins 14 to move closer or further apart. As a result, the two sets of symmetrically distributed limit rollers 10 will adjust their distance to change the specifications of the subsequent bending of the workpiece.

[0038] The scale bar 7 corresponds to the slider 9, which allows for precise adjustments.

[0039] When the workpiece is bent, the limiting plate 11 limits its side. Separate the limiting threaded rod 16 from the positioning post 14, remove the collar frame 15 from the positioning post 14, and then the limiting roller 10 can be separated from the slider 9. Conversely, the installation work can be carried out quickly.

[0040] During the horizontal adjustment of slider 9, positioning post 14 will slide on the inner wall of horizontal limiting groove 13.

[0041] The drive motor 12 can be replaced with a manual turntable for adjustment.

[0042] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
