[0002] The wind power tower frame door usually refers to the entrance or door frame structure of the wind power tower in a wind farm. The door frame is designed to facilitate the entry of personnel and equipment into the interior of the wind power tower, while ensuring the structural sealing and safety. During its processing, due to the need to ensure the structural sealing and safety to prevent the external environment (such as wind, rain, dust) from entering the tower interior and to ensure that the door frame can withstand various forces and pressures during the high-speed operation of the wind power tower, welding is required during the processing of the wind power tower frame door.

[0003] During welding, the corresponding workpieces need to be placed on the top of the workbench for positioning and fixing. The existing workbenches are mostly fixed support planes, which cannot adjust the angle of the workpieces or flip them as needed, and the workbench cannot be flexibly adjusted according to the needs of welding.

Detailed implementation mode

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figure 1 , 2 As shown in Figures 3 and 4, the present invention provides a technical solution: A workbench for welding processing, including: The accommodating box 1 is a cavity with an opening at the top; The hollow frame 2 is rotatably placed in the accommodating box 1, and a positioning component is arranged on the outer side of the hollow frame 2. The positioning component includes a first support frame 4 for positioning from both ends and a second support frame 6 for side positioning; The driving part is placed at the end of the accommodating box 1 for driving the hollow frame 2 to rotate; The support plate 3 is placed in the middle of the hollow frame 2 for use as an operating table.

[0024] It should be noted that the present invention adjusts the position of the second support frame 6. Due to the joints at both ends of the welding position and the chamfered notches are provided at the corners of the support plate 3, the edge of the wind power tower door frame is clamped in the middle of the first support frame 4 and the second support frame 6, and it is welded by a corresponding welding machine. After one side is welded, the driving part drives the hollow frame 2 to rotate to weld the joint again. When the welding is completed, the support plate 3 can be rotated upwards, and at this time, the top of the support plate 3 is flush with the top of the hollow frame 2, so that the support plate 3 can be used as an assembly workbench.

[0025] Please refer to Figure 1 , 4 As shown in the figure, it also includes a support platform 9 fixedly connected to one side of the accommodating box 1. A moving seat 10 is slidably connected to the middle of the support platform 9, and a linear module 15 is fixedly connected to one side of the accommodating box 1. The moving slide of the linear module 15 is fixedly connected to the moving seat 10.

[0026] It should be noted that in the present utility model, a welding robot is connected to the moving base 10. The linear module 15 is a synchronous belt linear module. The linear module 15 includes a bracket with a guide rail installed thereon, a moving slide table slidably disposed on the guide rail, a synchronous belt assembly for driving the movement of the moving slide table, and a servo motor for driving the rotation of the synchronous belt assembly. The moving base 10 is driven by the linear module 15 to slide on the top of the support table 9, so that the welding robot can move along the X-axis direction on one side of the accommodation box 1.

[0027] Please refer to Figure 3 As shown in the figure, the first support frames 4 are placed at both ends of the hollow frame 2. Limiting rods 13 slidably connected to the hollow frame 2 are fixedly connected to the bottoms of the first support frames 4. First adjusting screws 14 are threadedly connected to the ends of the hollow frame 2. The tops of the first adjusting screws 14 are rotatably connected to the first support frames 4. A first pressing plate 5 is slidably connected to the middle of the first support frame 4. One end of the first pressing plate 5 is threadedly connected to a second adjusting screw 18. One end of the second adjusting screw 18 is rotatably connected to the first pressing plate 5.

[0028] It should be noted that in the present utility model, the upper and lower ends of the wind power tower door frame are of an arc structure. Therefore, during welding, the end support fixture needs to be adjusted to be higher than the fixtures on both sides. By rotating the first adjusting screw 14, the linear module 15 drives the first support frame 4 to move under the action of the thread. The first support frame 4 drives the limiting rod 13 to move upward. The second adjusting screw 18 is rotated according to the thickness of the door frame, so that the second adjusting screw 18 drives the first pressing plate 5 to move to one side, thereby clamping and fixing the end of the door frame through the first pressing plate 5.

[0029] Please refer to Figure 1 、 2 As shown in FIGS. 4, a plurality of second support frames 6 are provided. The plurality of second support frames 6 are detachably installed on the outer side of the hollow frame 2. A cylinder 7 is fixedly connected to one side of the second support frame 6. The output end of the cylinder 7 is fixedly connected to a second pressing plate 8. A limiting plate 17 with an inclined surface structure is provided on one side of the second pressing plate 8 for pressing and fixing the door frame.

[0030] It should be noted that in the present utility model, the side of the door frame is placed in the groove on the top of the second support frame 6. The cylinder 7 drives the second pressing plate 8 to move to fix the side. Since the bottom of the limiting plate 17 on one side of the second pressing plate 8 is of an inclined surface structure, a downward force is exerted on the door frame during the pressing process, so that the door frame is pressed and fixed in the second support frame 6.

[0031] Please refer to Figure 3 、 4 As shown in the figure, the driving part includes a speed reducer 11 fixedly connected to the outer side of the accommodation box 1. The output end of the speed reducer 11 is fixedly connected to the end of the hollow frame 2. A driving motor 12 is installed at the input end of the speed reducer 11.

[0032] It should be noted that the speed reducer 11 of the present utility model is a worm and worm gear speed reducer. The driving motor 12 is fixedly connected to the worm. The middle part of the worm gear is connected to the hollow frame 2 through a rotating shaft. The driving motor 12 drives the worm gear through the worm, and drives the hollow frame 2 to rotate through the worm gear, so as to rotate and adjust the angle of the hollow frame 2.
