[0019] See attached Figure 1-3 An automatic welding positioner device comprises a base 1, a support seat 2 is symmetrically arranged on the upper end of the base 1, and arc-shaped grooves 3 are arranged on the tops of the two support seats 2, and a rotating bearing 4 matching with the arc-shaped grooves 3 is arranged in the arc-shaped grooves 3.

[0020] A driving motor 5 is fixed to the upper center end of the base 1, and a first transmission shaft 6 is connected to the output end of the driving motor 5. A first bevel gear 12 is fixed to the first transmission shaft 6. A universal joint 7 is connected to the upper end of the first transmission shaft 6. A second transmission shaft 8 is connected to the upper end of the universal joint 7. A workbench 9 is connected to the top of the second transmission shaft 8. A support plate 10 is provided between the workbench 9 and the universal joint 7. A rotating groove 11 matching the rotating bearing 4 is symmetrically provided at the bottom of the support plate 10.

[0021] The first bevel gear 12 is horizontally connected to the second bevel gear 13 outwardly, and the second bevel gear 13 is connected to the third transmission shaft 14 on the side away from the first bevel gear 12. A telescopic cylinder 15 is arranged below the third transmission shaft 14, and the bottom of the telescopic cylinder 15 is fixed on the base 1. A guide hole 16 is arranged on the top of the telescopic end of the telescopic cylinder 15. The third transmission shaft 14 passes through the telescopic end and communicates with the guide hole 16. A spur gear 17 is fixed on the third transmission shaft 14 located in the guide hole 16, and a rack 18 matching the spur gear 17 is arranged on the guide hole 16 in the vertical direction. An angle adjustment rod 19 is connected to the upper end of the rack 18, and the other end of the angle adjustment rod 19 is connected to one side of the lower surface of the support plate 10. Its function or effect: when the positioner can adjust the angle, the load on the workbench is reduced, the service life of the positioner is increased, and it is driven by a driving motor 5, which effectively saves energy; and the workbench 9 can be rotated independently, and at the same time, the meshing or disconnecting state of the first bevel gear 12 and the second bevel gear 13 is utilized to change the angle between the workbench 9 and the horizontal plane, and the connection between the spur gear 17 and the rack 18 can not only change the angle, but the gear 17 also plays a supporting and fixing role.

[0022] The lower surface of the workbench 9 is provided with a first rolling groove 20 centered on the rotation axis of the second transmission shaft 8, the upper surface of the support plate 10 is provided with a second rolling groove 21 opposite to the first rolling groove 20, and a rolling body 22 is provided between the first rolling groove 20 and the second rolling groove 21. Its function or effect: improve the rotation efficiency of the workbench on the upper end of the support plate 10, so that the workbench 9 of the positioner reaches an ideal welding position.

[0023] A predetermined distance is set between the workbench 9 and the support plate 10. Its function or effect: reduce or avoid friction between the workbench 9 and the support plate 10, effectively reduce the friction coefficient between the workbench 9 and the support plate 10, thereby avoiding large-area mechanical wear and improving service life.

[0024] The driving motor 5, the first bevel gear 12 and the second bevel gear 13 are provided with protective sleeves.

[0025] The support plate 10 is internally fixed with a bearing Ⅰ23, and the bearing Ⅰ23 is sleeved and fixed on the second transmission shaft 8. Its function or effect is to reduce the friction between the second transmission shaft 8 and the support plate 10, and effectively fix the support plate 10 while adjusting the angle.

[0026] When in use, the workpiece is placed on the workbench 9 and fixed. When the angle needs to be adjusted, the driving motor 5 is started so that the power is transmitted from the first transmission shaft 6, the universal joint 7, and the second transmission shaft 8 in sequence. The upper end of the second transmission shaft 8 is fixed to the workbench 9, which makes the workbench 9 rotate about the central axis of the second transmission shaft 8. The first bevel gear 12 fixed on the first transmission shaft 6 transmits the power to the second bevel gear 13 and the third transmission shaft 14 in sequence, thereby driving the spur gear fixed on the third transmission shaft 14 inside the guide hole 16 to rotate. A rack 18 matching the spur gear 17 is provided in the guide hole 16, so that the rack 18 moves up and down. The angle adjustment rod 19 connected to the upper end of the rack 18 is used to effectively adjust the angle to avoid the mechanical inability to rotate when the rack 18 moves up and down, so as to adjust the angle between the workbench 9 and the horizontal plane.

[0027] If the angle adjustment rod 19 is removed, a slide groove can be set under the support plate 10, and the slide groove matches the top of the rack 18, so that under the action of the drive motor 5, the rack 18 can be driven up and down to effectively adjust the angle. In order to prevent the rack 18 from detaching from the slide groove at the lower end of the support plate 10, the cross-section of the slide groove can be set to T-shaped, and limit blocks are set at both ends. A T-shaped structure matching the slide groove is set on the top of the rack 18, so as to achieve effective angle adjustment while preventing the rack 18 from detaching from the support plate 10.

[0028] When the workpiece on the workbench 9 reaches the ideal processing position, the drive motor 5 can be disconnected, or the telescopic cylinder 15 can be started to disengage the first bevel gear 12 and the second bevel gear 13 from each other; that is, the workbench can rotate alone to reach the ideal processing position, or the meshing or disengagement state of the first bevel gear 12 and the second bevel gear 13 can be combined to change the angle between the workbench and the horizontal plane, so that the workpiece on the workbench 9 reaches the ideal processing position.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
