Micro-holes are ubiquitous. Like other special processing technologies, ultrasonic vibration processing technology is also undergoing continuous improvement, developing towards higher precision, miniaturization, and higher efficiency.

[0057] Working principle: The double-headed cylinder 221 drives the two connecting rods 222 to move relative to each other, thereby moving the two guide blocks 223. The width of the workpiece to be drilled is adjusted as needed. After adjustment, the workpiece is placed on the placement seat 29. The two sides of the workpiece slide downwards on the guide blocks 223, thus placing the workpiece in the middle position of the placement seat 29. Then, the second motor 31 drives the second gear 32 to rotate, thereby moving the four racks 36, which in turn move the four sliding rods 33 along the inclined groove to clamp and fix the workpiece. After the workpiece is fixed, the first motor 213 drives the first gear 214 to rotate. The rotation of the first gear 214 drives the annular half-gear ring 212 to rotate, thereby rotating the electric push rod 215, thus adjusting the position of the electric push rod 215. The rotation of the electric push rod 215 drives the movable block 218 to rotate through the third ball bearing 220. Then, the electric push rod 215... 15. The movable block 218 is raised or lowered. The movable block 218 will raise or lower one end of the placement seat 29 through the second ball bearing 217, thereby adjusting the angle of the placement seat 29 according to the angle of the workpiece to be drilled. After the adjustment is completed, the laser positioner 105 irradiates the workpiece with laser light. Then, the third motor 102 is started to drive the rotating shaft 103 to rotate. The rotating shaft 103 drives the two swing plates 104 to swing in opposite directions through the gear set, thereby driving the two laser positioners 105 to swing, so that the laser points irradiated by the laser positioners 105 on the workpiece coincide, thereby determining the drilling position. The linear motor 23 is started to drive the connecting plate 24 to move, which in turn drives the moving seat 25 to move, adjusting the position of the workpiece so that the position to be drilled coincides with the laser point, thereby achieving precise drilling. After the workpiece position is adjusted, the hydraulic cylinder 5 is started to drive the cutter 9 to descend, and the workpiece is drilled by ultrasonic vibration.

Many methods and approaches exist for implementing this technical solution; the above description is merely a preferred embodiment of the invention.
