The cutter head assembly 2 comprises a cutter head 21 and a cutter frame 22, and the cutter head 21 is fixed on the machine frame 1 through the cutter frame 22.
As shown in fig. 3, the tool bit 21 includes a tool body 211, a node positioning block 2111 is disposed at an acoustic node position on a side surface of the tool body 211, and the node positioning block 2111 is provided with an acoustic damping structure; the cutter head 21 further includes two transducers 213 symmetrically arranged to convert electrical energy into mechanical energy of ultrasonic vibration; an amplitude modulator 212 is respectively arranged between each transducer 213 and the blade body 211, and the amplitude of the ultrasonic vibration can be adjusted. The tool rest 22 comprises a frame body 221, the frame body 221 comprises a through groove-shaped structure, the tool bit 21 penetrates through the groove-shaped structure to be installed, a clamping portion corresponding to the node positioning block 2111 is arranged on the inner side wall surface of the groove-shaped structure, and when the clamping portion is matched with the node positioning block 2111 in a clamping mode, the parallelism of the tool bit 21 and the tool apron 3 meets the operation requirement. The micrometer 31 can adjust and measure the cutting work area 4. When the ultrasonic cutting equipment works, the vibration of the acoustic node position is the weakest, and the node positioning block is provided with the damping structure, so that the vibration and the abrasion of the clamping part are within a design allowable range. The cutter head 21 is provided with a fixing plate 214 which is fixedly connected with the amplitude modulator 212 through an anchor ear mechanism 215, and the positioning rod 216 is used for installing a medium supporting structure 223 of a hard spring and assisting in determining the installation position of the fixing plate 214; the two sets of support plates 222 are respectively and fixedly connected to two ends of the fixing plate 214, and serve as force bearing structures to support the cutter head 21. The connecting piece 224 is arranged in the middle of the frame 221, and in combination with fig. 1, the connecting piece 224 is connected with the servo motor 11 on the frame 1, so that the servo motor 11 can drive the cutter head assembly 2 to move up and down, and the distance of the cutting working area 4 is adjusted to adapt to materials to be processed with different thicknesses. The guiding mechanisms 225 are disposed at two ends of the groove structure of the frame 221, and are used for limiting the movement of the cutter head assembly 2 in the horizontal direction when the servo motor moves, so as to avoid deviation and influence on the precision and effect of ultrasonic cutting. A pair of intermediate support structures 223 made of hard springs are symmetrically disposed between each fixing plate 214 and the frame body 221 for supporting the cutter head 21 in place of the support plate 222 during mounting and dismounting.
