[0002] The application of ultrasonic tools in the industrial field is mainly reflected in ultrasonic vibration cutting technology. This technology enables the tool to vibrate at a certain frequency along the cutting direction at high speed, achieving high-quality processing of difficult-to-machine materials. Its advantages include small cutting force, high machining accuracy, low cutting temperature, and small workpiece deformation. In addition, ultrasonic vibration cutting is also widely used in industries such as aerospace, automotive, and 3C to solve the processing problems of difficult-to-machine materials, honeycomb composite materials, and soft materials.

[0003] When the existing ultrasonic tools are in processing, a machine tool is required for the cutting process of the tool head.

Therefore, it is necessary to design an external mounting structure for an ultrasonic tool to address the above problems. Content of the Utility Model

[0011] Preferably, the centers of the clamping plate, the adjusting plate and the substrate are located on the same horizontal plane, and the centers of the substrate and the machine tool spindle are located on the same horizontal plane.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: for this ultrasonic tool external mounting structure, a new structural design is adopted.

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.

[0021] Please refer to Figures 1-4 , the present invention provides a technical solution: an external installation structure for an ultrasonic tool, including a machine tool body 1, a machine tool spindle 2, a pneumatic telescopic rod 3, a substrate 4, a stabilizing rod 5, a stabilizing hole 6, a rotating shaft 7, an adjusting plate 8, an installation groove 9, a servo motor 10, a horizontal threaded rod 11, a movable plate 12, a linking rod 13, a storage groove 14, a clamping plate 15 and an ultrasonic tool handle 16. The machine tool spindle 2 is installed on the machine tool body 1. One side of the machine tool body 1 is fixedly installed with a pneumatic telescopic rod 3. The end of the pneumatic telescopic rod 3 is connected and fixed to one end of the back surface of the substrate 4. The pneumatic telescopic rods 3 are symmetrically distributed about the center of the substrate 4, and the pneumatic telescopic rods 3 and the substrate 4 are parallelly distributed. The above structural design ensures that the pneumatic telescopic rod 3 can drive the substrate 4 to perform stable linear displacement;

[0022] When using this device, first select a suitable cutting tool and install the cutting tool on the machine tool spindle 2, and then use the clamping plate 15 to connect and fix the ultrasonic tool handle 16 to the adjusting plate 8;

[0023] A stabilizing rod 5 is fixedly installed on the side of the machine tool body 1. The stabilizing rod 5 is in contact with the inner wall of the stabilizing hole 6. The stabilizing hole 6 is opened at one end of the substrate 4. The above structural design enables the substrate 4 to linearly displace along the stabilizing rod 5 when driven by the pneumatic telescopic rod 3, further improving the stability of the substrate 4 and the installation structure thereon. The stabilizing rod 5 and the stabilizing hole 6 are in sliding connection. The length of the stabilizing hole 6 exceeds 3 / 4 of the length of the substrate 4. The stabilizing rod 5 and the pneumatic telescopic rod 3 are parallelly distributed. The above structural design ensures that the stabilizing hole 6 will not be separated from the stabilizing rod 5, and the substrate 4 can smoothly linearly displace along the stabilizing rod 5 with the stabilizing hole 6. One end of the front surface of the substrate 4 is rotatably connected to the adjusting plate 8 through a rotating shaft 7. An installation groove 9 is opened on the front surface of the substrate 4. A servo motor 10 is fixed at one end inside the installation groove 9. The output end of the servo motor 10 is provided with a horizontal threaded rod 11. The horizontal threaded rod 11 is rotatably installed in the installation groove 9. One end of the horizontal threaded rod 11 is provided with a movable plate 12. The horizontal threaded rod 11 is symmetrically distributed about the center of the movable plate 12. The horizontal threaded rod 11 is in threaded connection with the movable plate 12. The movable plate 12 is in sliding connection with the installation groove 9. The above structural design enables the horizontal threaded rod 11 to drive the movable plate 12 to stably slide and displace along the installation groove 9 when rotating;

[0024] A linkage rod 13 is rotatably installed on the front surface of the movable plate 12. The end of the linkage rod 13 is rotatably connected to one end of the storage groove 14. The storage groove 14 is opened on the back surface of the adjusting plate 8. The linkage rods 13 are equally spaced on the front side surface of the movable plate 12. The length of the linkage rod 13 is greater than half of the length of the adjusting plate 8. The above structural design enables the linkage rod 13 to stably position the adjusting plate 8 when stationary and stably drive the adjusting plate 8 when rotating. The ultrasonic tool handle 16 is installed on the front surface of the adjusting plate 8 through a clamping plate 15. The centers of the clamping plate 15, the adjusting plate 8 and the substrate 4 are on the same horizontal plane. The centers of the substrate 4 and the machine tool spindle 2 are on the same horizontal plane. The above structural design ensures that the ultrasonic tool tip at the end of the ultrasonic tool handle 16 fixed by the clamping plate 15 can be stably aligned with the cutting tool installed on the machine tool spindle 2;

[0025] Start the machine tool body 1, control the pneumatic telescopic rods 3 symmetrically distributed to extend synchronously. The pneumatic telescopic rods 3 push the substrate 4 to drive the stable hole 6 to feed stably along the stable rod 5 in a straight line. When the feeding distance is sufficient, control the pneumatic telescopic rods 3 to stop working. Control the servo motors 10 symmetrically distributed to drive the horizontal threaded rods 11 to rotate forward synchronously. The horizontal threaded rods 11 rotate to drive the movable plate 12 to slide linearly along the installation groove 9. During the displacement process of the movable plate 12, it drives the linkage rod 13 to rotate. The linkage rod 13 pushes the adjusting plate 8 to drive the clamping plate 15 and the ultrasonic tool handle 16 to rotate and adjust with the rotating shaft 7 as the center until the machining direction of the ultrasonic tool tip at the end of the ultrasonic tool handle 16 is appropriate. Control the servo motors 10 to stop working and lock the horizontal threaded rods 11. The horizontal threaded rods 11 use thread self-locking to fix the position of the movable plate 12. The movable plate 12 and the linkage rod 13 position the clamping plate 15 and the ultrasonic tool handle 16 to ensure the stable machining of the ultrasonic tool tip.
