[0018] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments. However, the following embodiments are only the preferred embodiments of the present invention, not all of them. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without creative work all belong to the protection scope of the present invention. The experimental methods in the following embodiments are all conventional methods unless otherwise specified, and the materials, reagents, etc. used in the following embodiments can all be obtained from commercial channels unless otherwise specified.

[0019] Embodiment: As Figure 1 - Figure 7 shown, this embodiment proposes a device for opening the internal thread of a gearbox plug, including a frame 1, an internal thread opening component, a clamping seat 2, a rotating component, a moving seat 3, and a distance adjusting component. The internal thread opening component is arranged on the frame 1, the clamping seat 2 is arranged on the base through the rotating component, and the base is installed on the upper surface of the moving seat 3; Wherein, the moving seat 3 moves in the frame 1 through the distance adjusting component to adjust the distance of the clamping seat 2, so that the clamping seat 2 moves to the vertical lower part of the internal thread opening component to complete the opening of the internal thread of the plug. By rotating the rotating rod 6, as the external thread 7 on the left side is adapted to the internal thread 10, the rotating rod 6 is driven to axially feed the limiting block 9 in the moving groove 5 towards the plug direction, so that the four limiting blocks 9 clamp and fix the plug where the internal thread is about to be opened, ensuring accurate positioning of the blank, reducing the deviation of the internal thread opening caused by clamping errors. And during the internal thread opening process, the lifting of the lifting seat 25 can drive the drilling bit away from the inside of the plug. After rotating the second handle 19, the worm 18 rotates, and the worm wheel 17 meshing with it rotates accordingly and drives the clamping seat 2 to rotate. The staff can perform dimensional inspection and surface quality inspection, so as to timely detect and correct processing errors. The plug can rotate with the clamping seat 2, and the staff can detect the whole circumference of the plug without moving it.

[0020] A slot 4 for inserting the plug is centrally opened on the surface of the clamping seat 2, and four moving grooves 5 are equidistantly spaced around the slot 4 in the clamping seat 2. A rotating rod 6 is arranged in the moving groove 5. A plum blossom hole is opened on one side of the rotating rod 6 away from the slot 4, so as to facilitate the insertion of a plum blossom wrench to drive its rotation. External threads 7 are respectively arranged on the left side and the right side of the rotating rod 6, and the external thread 7 on the left side is not connected to the external thread 8 on the right side. When it is necessary to fix and limit the plug blank in the slot 4, rotate the rotating rod 6 clockwise. As the external thread 7 on the left side is adapted to the internal thread 10, the rotating rod 6 drives the limiting block 9 to axially feed and move in the moving groove 5 towards the plug direction, so that the four limiting blocks 9 clamp and fix the plug, ensuring accurate positioning of the blank and reducing the deviation of the internal thread opening caused by clamping errors. After the internal thread is opened, rotate the rotating rod 6 in the reverse direction. As the external thread 8 on the right side is adapted to the internal thread 10, the rotating rod 6 can drive the limiting block 9 to move in the moving groove 5 towards the direction away from the plug, and then cancel the fixation of the plug, so as to facilitate the staff to take out the processed plug. A limiting block 9 is also arranged in the moving groove 5. Internal threads 10 adapted to the external thread 7 on the left side and the external thread 8 on the right side are opened on the lower surface of the limiting block 9. The internal thread 10 is provided with two parts, and the two parts of the internal thread 10 are not connected. The two parts of the internal thread 10 are respectively adapted to the external thread 7 on the left side and the external thread 8 on the right side, so as to realize the conversion of the axial feeding direction of the rotating rod 6.

[0021] Among them, the distance adjustment component includes a first convex block 11 provided on the upper surface inside the frame 1. A first groove 12 is formed in the first convex block 11. A first threaded rod 13 is inserted into the first groove 12. One end of the first threaded rod 13 extending outside the first convex block 11 is connected to a first handle 14. As the first handle 14 rotates, a first screw sleeve 15 is sleeved on the first threaded rod 13. The first screw sleeve 15 is connected to the lower surface of the moving seat 3. A first slide rail 16 adapted to the first convex block 11 is further formed on the lower surface of the moving seat 3. Both sides of the surface of the first convex block 11 extend outward with protrusions. As the first slide rail 16 slides along the length direction of the protrusions, rotational limit can be imposed on the first screw sleeve 15, converting the rotational motion into a linear motion, and then driving the first screw sleeve 15 to move on the first threaded rod 13, thereby driving the movement of the moving seat 3, and moving the plug held in the clamping seat 2 to the vertical lower side of the hole drilling bit 33, which is convenient for the subsequent opening of the internal thread. It further includes a height adjustment component. The height adjustment component includes a second convex block 21 provided on the surface of the frame 1. A second groove 22 is formed in the second convex block 21. A second threaded rod 23 is inserted into the second groove 22. The top of the second threaded sleeve extends outside the second convex block 21 and is connected to a third handle 34. A second screw sleeve 24 is sleeved on the second threaded rod 23. A lifting seat 25 is provided on the second convex block 21. A second slide rail 26 adapted to the second convex block 21 is formed on one side of the lifting seat 25 facing the second convex block 21. The second screw sleeve 24 is connected to the lifting seat 25. After the plug moves to the vertical lower side of the hole drilling bit 33, the surface of the second convex block 21 also extends outward with convex parts on both sides. By sliding the second slide rail 26 along the length direction of the convex parts, rotational limit can be imposed on the second screw sleeve 24, enabling the second screw sleeve 24 to move on the second threaded rod 23, and further driving the lifting of the lifting seat 25, so that the support frame 27 drives the hole drilling bit to insert into the plug, completing the opening of the internal thread.

[0022] Further, the rotating assembly includes a worm wheel 17 and a worm 18 disposed within the base. The worm wheel 17 meshes with the worm 18. The worm 18 extends outside the base and is connected to a second handle 19. A connecting rod 20 is inserted into the worm wheel 17. The connecting rod 20 extends to the upper surface of the base and is connected to the lower surface of the clamping seat 2. A turntable is provided at the bottom of the clamping seat 2. The connecting rod 20 extends to the upper surface of the base and is connected to the turntable. During the threading process, after the threading drill is driven away from the plug by the movement of the lifting seat 25, the second handle 19 is rotated to drive the rotation of the worm 18. Through the meshing of the worm 18 with the worm wheel 17, the worm wheel 17 is driven to rotate, causing the connecting rod 20 to drive the turntable to rotate, and then driving the rotation of the clamping seat 2 and the plug. At this time, the operator can perform dimensional inspection and surface quality inspection on the entire circumference of the plug without moving, and promptly discover and correct machining errors. The internal threading assembly includes a support frame 27 disposed outside the lifting seat 25. A motor 28 is provided on the upper surface of the support frame 27. The power output end of the motor 28 extends into the support frame 27 and is connected to a first pulley 29. A transmission belt 30 is provided on the first pulley 29. The other end of the transmission belt 30 is connected to a second pulley 31. A rotating shaft 32 is inserted into the second pulley 31. The rotating shaft 32 extends vertically below the support frame 27 and is connected to a threading drill 33. By driving the first pulley 29 to rotate by the motor 28, the second pulley 31 is driven to rotate under the transmission of the transmission belt 30, and then the rotating shaft 32 is driven to rotate, causing the threading drill to be driven to perform internal threading on the plug.

[0023] A method for using an internal threading device for a gearbox plug, the specific steps are as follows: S1. First, insert the plug to be internally threaded into the slot 4, and rotate the rotating rod 6. Through the cooperation of the external thread 7 on the left and the internal thread 10, drive the rotating rod 6 to axially feed in the moving slot 5, so that the four limiting blocks 9 clamp and fix the plug in the slot 4; S2. Rotate the first handle 14 to drive the rotation of the first threaded rod 13. With the cooperation of the first slide rail 16 and the first convex block 11, limit the rotation of the first nut 15, and let the first nut 15 slide along the length direction of the first threaded rod 13, thereby driving the movement of the moving seat 3, and moving the plug to directly below the threading drill 33; S3. Rotate the third handle 34 to drive the rotation of the second threaded rod 23. With the cooperation of the second slide rail 26 and the second convex block 21, limit the rotation of the second nut 24, and let the second nut 24 slide along the length direction of the second threaded rod 23, driving the lifting of the lifting seat 25, and causing the support frame 27 to drive the threading drill to descend into the plug; S4. Start the motor 28. The power output end of the motor 28 drives the first pulley 29 to rotate. Through the transmission of the transmission belt 30, the second pulley 31 is driven to rotate, and then the rotating shaft 32 is driven to rotate, causing the opening drill bit to rotate, so as to open the internal thread of the plug. S5. After the opening is completed, rotate the second handle 19 to drive the worm 18 to rotate. Through the meshing of the worm 18 and the worm wheel 17, the worm wheel 17 is driven to rotate, and the connecting rod 20 drives the clamping seat 2 to rotate.
