[0025] Please see Figures 1-2 In this embodiment of the present invention, an automatic lathe tail screw removal structure includes a connecting plate 19 and a mounting plate 20. One end of the connecting plate 19 is fixedly connected to the mounting plate 20, and the two are connected in a vertical structure, together forming the basic support frame of the entire device.

[0026] Mounting plate 20, as one of the main supporting components of the device, is vertically fixed to connecting plate 19. A chuck moving seat 6 is mounted on the upper end, and a linear track 10 is provided to provide a mounting base and movement guide for components such as the chuck moving seat 6, ensuring that the chuck moving seat 6 can move stably and smoothly.

[0027] The lower end of the chuck moving base 6 is provided with a slider, and the upper end of the slider has a sliding groove. The sliding groove engages with the linear track 10 provided on the mounting plate 20. A first push plate 5 is installed at one end, and an adjustment structure is provided at the upper end. It can move along the linear track 10 on the mounting plate 20, thereby adjusting the position of the gripping chuck 9 and the workpiece it holds, so as to perform the tail screw removal operation. At the same time, it provides an installation position for the adjustment structure and the first push plate 5.

[0028] The first push plate 5 is sleeved on the first lead screw nut 4 and connected to the chuck moving seat 6, transmitting the moving force of the first lead screw nut 4 to the chuck moving seat 6, pushing the chuck moving seat 6 to move along the linear track 10.

[0029] The first lead screw 3 is installed inside the first lead screw nut 4 and is fixedly connected to the first push plate 5. Under the rotation of the first lead screw 3, it moves linearly, and then drives the chuck moving seat 6 to move through the first push plate 5.

[0030] One end of the first lead screw 3 is connected to the first coupling 2 and passes through the inside of the first lead screw nut 4. It rotates under the drive of the first servo motor 1, converting the rotational motion into the linear motion of the first lead screw nut 4. One end of the first coupling 2 is connected to the first lead screw 3, and the other end is connected to the first servo motor 1, realizing the power transmission between the first servo motor 1 and the first lead screw 3 and ensuring their synchronous rotation. The first servo motor 1 is connected to one end of the first coupling 2 to provide power, which drives the first lead screw 3 to rotate through the first coupling 2, and is the power source for the movement of the chuck moving seat 6.

[0031] The adjustment structure includes a left-right adjustment seat 7 and a right-right adjustment seat 8, both of which are L-shaped. The right-right adjustment seat 8 is located at the upper end of the left-right adjustment seat 7, and a rectangular limiting support block is provided at the lower end of the left-right adjustment seat 7. The right-right adjustment seat 8 is fixedly connected to the chuck moving seat 6 by fine-thread screws. One side of the left-right adjustment seat 7 and the right-right adjustment seat 8 are fixedly connected by fine-thread screws. One end of the left-right adjustment seat 7 is fixedly connected to the gripping chuck 9, and both the upper and lower ends of the left-right adjustment seat 7 are fixed. By adjusting the fine-thread screws, the relative positions of the left-right adjustment seat 7 and the right-right adjustment seat 8 can be changed, thereby fine-tuning the left-right and up-down positions of the gripping chuck 9 to ensure that the workpiece can be accurately clamped and positioned. The rectangular limiting support block plays a limiting and stabilizing role, ensuring the stability of the adjustment process.

[0032] The gripper 9 is mounted on the adjustment structure via a thumb cylinder. Driven by the thumb cylinder, it opens and closes to grip and fix the workpiece, ensuring that the workpiece does not shift during the removal of the tail screw. One end of the connecting plate 19 is fixedly connected to the mounting plate 20, and a second servo motor 18 is provided on one side. It is slidably connected to the sliding seat 13 via a linear guide rail, providing mounting support for components such as the sliding seat 13 and the second servo motor 18. At the same time, it forms a stable overall frame with the mounting plate 20, ensuring the structural stability of the device.

[0033] The second servo motor 18 is located on one side of the connecting plate 19, with one end connected to the second coupling 17, providing power for the movement of the sliding seat 13. The second coupling 17 drives the second lead screw 16 to rotate. One end of the second coupling 17 is connected to the second servo motor 18, and the other end is connected to the second lead screw 16, transmitting the power of the second servo motor 18 to the second lead screw 16, causing them to rotate synchronously. One end of the second lead screw 16 is connected to the second coupling 17, with a second lead screw nut 15 fitted onto it. Driven by the second servo motor 18, it rotates, converting the rotational motion into the second servo motor 18. The linear motion of the second lead screw nut 15 is achieved by the second lead screw nut 15 being sleeved on the second lead screw 16, with a sliding seat 13 installed at one end. Under the rotation of the second lead screw 16, the nut 15 moves linearly, causing the sliding seat 13 to slide along the linear guide rail on the connecting plate 19. One end of the sliding seat 13 is connected to the second lead screw nut 15 and is slidably connected to the connecting plate 19 via the linear guide rail. A support arm 12 is provided on the upper end of one side, which can slide along the linear guide rail on the connecting plate 19. This allows the support arm 12 and the milling tail screw electric spindle 11 to adjust their positions, enabling them to accurately align with the tail screw of the workpiece for processing.

[0034] The support arm 12 is fixedly connected to the sliding seat 13 by bolts, and the top is fixedly connected to the milling tail screw electric spindle 11 by the mounting block, which serves as a connection and support, fixing the milling tail screw electric spindle 11 on the sliding seat 13 and moving together with the sliding seat 13.

[0035] The tail screw milling spindle 11 is mounted on one end of the support arm 12, above the gripper 9. As the execution component for tail screw removal, it can rotate at high speed to mill and remove the tail screws on the workpiece held by the gripper 9.

[0036] The linear track 10 is mounted on the mounting plate 20 and engages with the slide groove on the lower end of the chuck moving seat 6, providing guidance for the movement of the chuck moving seat 6 and ensuring that the chuck moving seat 6 moves smoothly along the fixed track.

[0037] The second push plate 14 has the same structure as the first push plate 5. It can refer to the function of the first push plate 5 and play the role of transmitting power and pushing related components to move in the corresponding transmission system.

[0038] The working principle of this utility model is as follows: When it is necessary to remove the tail screw from the workpiece, the workpiece is first gripped and fixed by the gripping chuck 9. The gripping chuck 9 is mounted on the thumb cylinder and can reliably hold the workpiece.

[0039] Driven by the first servo motor 1, the first lead screw 3 is rotated through the first coupling 2. The rotation of the first lead screw 3 causes the first lead screw nut 4 to move, which in turn pushes the chuck moving seat 6 along the linear track 10 on the mounting plate 20 through the first push plate 5, thereby realizing the adjustment of the position of the workpiece driven by the gripping chuck 9, so as to move the workpiece to the appropriate tail screw removal position.

[0040] Simultaneously, the second servo motor 18 starts, driving the second lead screw 16 to rotate via the second coupling 17. The rotation of the second lead screw 16 causes the second lead screw nut 15 to move, thereby driving the sliding seat 13 to slide along the linear guide rail on the connecting plate 19. The movement of the sliding seat 13 drives the support arm 12 and the milling tail screw electric spindle 11 to move, so that the milling tail screw electric spindle 11 reaches the position of the workpiece tail screw.

[0041] Since the milling tail screw electric spindle 11 is located above the gripper 9, when both the workpiece and the milling tail screw electric spindle 11 reach the appropriate position, the milling tail screw electric spindle 11 starts working to mill and remove the tail screw on the workpiece.

[0042] Throughout the process, if the position of the gripper 9 needs to be adjusted, it can be achieved through the adjustment structure. Both the left-right adjustment seat 7 and the up-down adjustment seat 8 are "L" shaped structures. The up-down adjustment seat 8 is fixedly connected to the chuck moving seat 6 by fine-thread screws. One side of the left-right adjustment seat 7 and the up-down adjustment seat 8 is fixedly connected by fine-thread screws. By adjusting these fine-thread screws, the relative positions of the left-right adjustment seat 7 and the up-down adjustment seat 8 can be changed, thereby adjusting the left-right and up-down positions of the gripper 9, ensuring that the workpiece can be accurately clamped and positioned, and ensuring the precision of the tail screw removal operation.

[0043] 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.
