[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figures 1-4 In this embodiment of the utility model, a positioner rotation positioning device includes a base plate 1. Vertical plates protruding upwards are welded to the top two sides of the base plate 1. A rotating shaft 2 is rotatably installed on the inner side of the vertical plate. A first forward and reverse rotating shaft motor 3 is installed on the outer side of one of the vertical plates. The first forward and reverse rotating shaft motor 3 is coaxially connected to the rotating shaft 2. A lower rotating plate 4 is fixedly installed at the end of the rotating shaft 2 away from the vertical plate through a connector. An upper rotating plate 5 is fixedly installed at the top four corners of the lower rotating plate 4 through vertical rods. A rotating mechanism extending above the upper rotating plate 5 is installed at the bottom end of the lower rotating plate 4. Positioning mechanisms are installed on the top two sides of the upper rotating plate 5.

[0015] In this embodiment: First, the workpiece to be welded is placed on top of the rotating mechanism. Then, the starting positioning mechanism is used to position and fix the placed workpiece. During the welding process, when adjusting the angle of the workpiece to be welded, the No. 1 forward and reverse rotating shaft motor 3 can be started. The No. 1 forward and reverse rotating shaft motor 3 drives the lower rotating plate 4 and the upper rotating plate 5 to rotate around the rotating shaft 2 through the rotating shaft 2, thereby adjusting the vertical angle of the workpiece. The angle direction of the workpiece on the horizontal plane can be controlled by the rotating mechanism. In this way, the workpiece can be adjusted to different angles to facilitate welding.

[0016] Please refer to this carefully. Figure 1 and Figure 2 The rotating mechanism includes a second forward and reverse rotating shaft motor 6 fixedly installed on one side of the bottom of the lower rotating plate 4. The rotating shaft of the second forward and reverse rotating shaft motor 6 passes through the lower rotating plate 4 and extends between the lower rotating plate 4 and the upper rotating plate 5. A small gear 10 is interference-fitted to the outer wall of the rotating shaft of the lower rotating plate 4. A large gear 11 meshes with the outer periphery of the small gear 10. A rotating disk 9 is coaxially connected to the top of the large gear 11. The rotating disk 9 is rotatably installed inside the upper rotating plate 5.

[0017] In this embodiment: when adjusting the angle of the workpiece on the horizontal plane, the No. 2 forward and reverse rotating shaft motor 6 is started. The No. 2 forward and reverse rotating shaft motor 6 drives the connected pinion 10 to rotate. The pinion 10 drives the large gear 11 to rotate synchronously. The rotating large gear 11 drives the rotating disk 9 to rotate, thereby adjusting the angle of the workpiece on the horizontal plane.

[0018] Please refer to this carefully. Figure 3 The positioning mechanism includes fixed rods 7 fixedly installed on the top of the upper rotating plate 5. The tops of the two fixed rods 7 are fixedly connected to the fixed ears at the end of a connecting plate 8. The bottom end of the connecting plate 8 is integrally formed with a guide slope. The positioning mechanism also includes a guide rail 21 fixedly installed on the top of the upper rotating plate 5 and perpendicular to the connecting plate 8. A sliding seat 12 is slidably installed on the inner wall of the guide rail 21. A guide plate 17 is fixedly installed on the top of the sliding seat 12. A positioning plate 13 is fixedly installed on one side of the guide plate 17. The top of the positioning plate 13 is formed with a pressure slope that matches the guide slope. An electric push cylinder 14 connected to the guide plate 17 is fixedly installed on the top of the base plate 1. The guide plate 17 is connected to the positioning plate 13 through a sliding assembly. A screw 15 is threadedly connected to one end of the positioning plate 13. An adjusting plate 16 is fixedly installed at the bottom end of the screw 15.

[0019] In this embodiment: After the workpiece is placed on the top of the rotating disk 9, two electric push cylinders 14 are started. The two electric push cylinders 14 operate synchronously under the control of the synchronizer (the electric push cylinders 14 in this application are equipped with displacement sensors, model: EAD series). The two electric push cylinders 14 operate synchronously and pull the guide plate 17 connected to them to move synchronously. The guide plate 17 drives the sliding seat 12 to slide along the inner wall of the guide rail 21. At the same time, the guide plate 17 pushes the positioning plate 13 to move. At this time, the pressure inclined surface of the positioning plate 13 moves downward while moving axially under the action of the guide inclined surface. At this time, the positioning plate 13 can move downward through the sliding assembly. The positioning plate 13 drives the adjusting plate 16 to move downward through the screw 15, pressing the edge of the workpiece to be welded, thereby achieving the positioning and fixing of the workpiece to be welded. If the thickness of the workpiece at the fixed position changes, the screw 15 can be rotated to drive the adjusting plate 16 to rotate downwards or upwards until the bottom end of the adjusting plate 16 is connected to the ball bearing to press the workpiece. This design can effectively avoid the problem of the workpiece being unable to rotate on the horizontal plane due to pressing when the rotating disk 9 is rotating.

[0020] Please refer to this carefully. Figure 4 The sliding assembly includes a vertical groove 18 formed on one side of the guide plate 17. A movable block 19 is slidably mounted on the inner wall of the vertical groove 18. The movable block 19 is fixedly connected to one end of the positioning plate 13. A spring 20 is fixedly mounted between the bottom end of the movable block 19 and the top end of the inner wall of the movable block 19.

[0021] In this embodiment: during the up-and-down sliding process of the positioning plate 13, the positioning plate 13 drives the moving block 19 to slide along the inner wall of the vertical groove 18. During this process, the spring 20 is compressed, so that the positioning plate 13 can move in the up-and-down direction.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
