[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] Embodiment, according to Figure 1-Figure 9 ,like Figure 1 In the embodiment of the present invention, a quick-change ultrasonic vibration-assisted sawing device includes a pneumatic ultrasonic sawing tool seat 1, a circular tool head driving seat 2, a tool head placement frame 3 rotatable outside the tool head driving seat 2, and a mounting frame 5 fixedly mounted at one end of the tool head driving seat 2, such as Figure 3 In the embodiment, three groups of slots are provided on the cutter head drive seat 2, such as Figure 4 In the embodiment, a plurality of spare tool holders 301 are rotatably mounted on the outside of the tool head placement rack 3 in a circular array, and a roller 302 is rotatably mounted on the spare tool holder 301, and further comprises: A brake assembly 4 installed in the cutter head drive seat 2 for decelerating and braking the cutter head placement rack 3; A quick-change assembly 6 mounted on the mounting frame 5 for quick change of the tool head; A cleaning assembly 7 mounted on the mounting frame 5 for cleaning the replaced blade head; A cutter head drying seat 8 is fixedly mounted on the cutter head driving seat 2 at one end away from the mounting frame 5 .

[0024] like Figure 3 In the embodiment, a high-speed motor is fixedly installed in the cutter head driving seat 2, a driving gear 201 is fixedly installed at the output end of the high-speed motor, and a gear ring meshing with the driving gear 201 is fixedly installed in the cutter head placement rack 3. By utilizing the meshing action of the driving gear 201 and the inner gear ring of the cutter head placement rack 3, the high-speed motor can drive the cutter head placement rack 3 to rotate rapidly. When in use, the high-speed motor drives the cutter head placement rack 3 to rotate through the meshing action of the driving gear 201 and the inner gear ring of the cutter head placement rack 3. The cutter head placement rack 3 rotates to achieve the purpose of switching and selecting the spare cutter heads.

[0025] like Figure 5 In the figure, the brake assembly 4 includes a first electric telescopic rod 401, a brake seat 402 and a cylinder 403. The first electric telescopic rod 401 is fixedly installed in the cutter head drive seat 2. The telescopic end of the first electric telescopic rod 401 is fixedly installed with a connecting seat 404. The brake seat 402 is provided with two first connecting rods 405 that are rotatably installed between the connecting seat 404. The outer end of the brake seat 402 is movably clamped with a brake pad 406. A first spring 407 is fixedly installed between the brake pad 406 and the brake seat 402. A second connecting rod 408 is fixedly installed at one end of the connecting seat 404. The cylinder 403 is fixedly installed on the cutter head drive seat 2. A longitudinal slot is opened on the cylinder 403, such as Figure 4In the embodiment, an NFC chip is integrated at the tail of the spare tool holder 301, and NFC sensors 303 are symmetrically fixedly installed on both sides of the bottom of the tool head placement rack 3. When the pressure hammer 409 contacts the limit plate on the top of the third connecting rod 410, the tool head placement rack 3 is completely braked. During use, when the spare tool holder 301 with the tool head to be replaced passes the NFC sensor 303, the first electric telescopic rod 401 retracts and drives the connecting seat 404 to drop straight down. At the same time, the first connecting rod 405 rotates and the angle between the two first connecting rods 405 increases, and drives the brake seats 402 on both sides to rotate toward the tool head driving seat 2, and the brake pads 406 contact the inner circle of the tool head placement rack 3 to achieve deceleration. At this time, the first electric telescopic rod 401 continues to retract, and the brake seat 402 rotates outward and compresses the first spring 407, thereby increasing the friction between the brake pads 406 and the tool head placement rack 3, and finally achieving the braking and stopping of the tool head placement rack 3. At the same time, the retraction action of the first electric telescopic rod 401 drives the spare tool holder 301 to turn for subsequent tool change.

[0026] like Figure 5 In the figure, the second connecting rod 408 extends into the cylinder 403 through the slot, and a pressure hammer 409 is fixedly installed at one end of the second connecting rod 408 located in the cylinder 403. A third connecting rod 410 is movably inserted at the bottom of the cylinder 403. A limiting plate is provided at the top of the third connecting rod 410, and a second spring 411 is provided between the limiting plate and the cylinder 403. A limiting clamping seat 412 is fixedly installed at the bottom of the third connecting rod 410, and the limiting clamping seat 412 is in a "C" shape. The limiting clamping seat 412 is movably clamped on the roller 302 of the lowermost spare knife seat 301. When in use, the connecting seat 404 descends and drives the pressure hammer 409 to descend through the second connecting rod 408. When the pressure hammer 409 contacts the top limit plate of the third connecting rod 410, the first spring 407 is continuously compressed, and the friction between the brake pad 406 and the tool head placement rack 3 is increased through the elastic force of the first spring 407, and finally the tool head placement rack 3 is completely stopped. At this time, the pressure hammer 409 continues to move downward and presses the third connecting rod 410 downward and compresses the second spring 411 at the same time. The third connecting rod 410 moves downward and drives the limit clamping seat 412 to move downward. Figure 7 In the process, the limit clamping seat 412 moves downward and drives the spare knife seat 301 to rotate downward by ninety degrees through the engagement with the roller 302 on the spare knife seat 301, thereby achieving the purpose of changing the orientation of the spare knife seat 301 to facilitate the subsequent knife changing operation.

[0027] like Figure 6In the embodiment, the quick-change assembly 6 includes a driving motor 601, a second electric telescopic rod 602, a gear sleeve 603 and a clamping rod 613. The driving motor 601 is fixedly mounted on the mounting frame 5. An active turntable 604 is fixedly mounted on the output end of the driving motor 601. A convex column 605 is provided on the active turntable 604. The second electric telescopic rod 602 is fixedly mounted on the mounting frame 5. A shaft sleeve 608 is fixedly mounted on the telescopic end of the second electric telescopic rod 602. The gear sleeve 603 is rotatably mounted on the shaft sleeve 608. A gear roller 606 is meshedly connected in the gear sleeve 603. A driven turntable 607 is fixedly mounted on the top of the gear roller 606. The driven turntable 607 is annularly provided with four slide grooves. The convex column 605 is slidably mounted on the driven turntable 607. 07, a cutter head clamping seat 609 is fixedly installed at the bottom of the gear sleeve 603. When in use, after the spare cutter seat 301 with the cutter head to be selected is installed facing downward, the driving motor 601 drives the active turntable 604 to rotate, and through the sliding limiting action of the convex column 605 and the slide groove on the driven turntable 607, the active turntable 604 rotates and drives the driven turntable 607 to rotate intermittently by 90 degrees, and the rotation of the active turntable 604 drives the gear roller 606 to rotate, and the rotation of the gear roller 606 drives the gear sleeve 603 and the cutter head clamping seat 609 to rotate, and the extension and retraction of the second electric telescopic rod 602 drives the gear sleeve 603 and the cutter head clamping seat 609 to move up and down through the shaft sleeve 608 (it will not affect the rotation of the cutter head clamping seat 609).

[0028] like Figure 8 In the embodiment, two spring sleeves are integrally formed at the bottom of the tool head clamping seat 609, and a limiting cone 610 is movably inserted in the spring sleeve. A third spring 611 is fixedly installed between the bottom of the limiting cone 610 and the spring sleeve. A push rod 612 is fixedly installed on the top of the limiting cone 610. The push rod 612 passes through the tool head clamping seat 609. Two clamping rods 613 are provided and are movably inserted on both sides of the tool head clamping seat 609. A fourth spring 614 for returning the clamping rod 613 is sleeved on the clamping rod 613. When in use, when the driving motor 601 drives the two ends of the tool head clamping seat 609 to be located directly below the pneumatic ultrasonic sawing tool seat 1 and the alternative tool seat, the second electric telescopic rod 602 retracts to drive the tool head clamping seat 609 to rise, and the tool head clamping seat 609 During the rising process, the push rod 612 is pushed back by the mounting frame 5, and drives the limiting cone 610 to move downward to compress the third spring 611. Due to the cone-shaped design of the limiting cone 610 and the elastic action of the fourth spring 614, the clamping rod 613 will be driven to retract, so that the tool head to be replaced on the spare tool seat 301 and the tool head on the pneumatic ultrasonic sawing tool seat 1 are respectively placed at the two ends of the tool head clamping seat 609. After completion, the second electric telescopic rod 602 pushes the tool head clamping seat 609 to move downward. According to the above principle, the clamping rod 613 is extended out of the slot on the tool head to clamp the tool heads on both sides. At the same time, the tool head clamping seat 609 is driven by the driving motor 601 to rotate 180 degrees and then rise, thereby achieving the purpose of automatic quick change of the tool head.

[0029] like Fig. 9 In the figure, the cleaning component 7 includes a cleaning seat 701 and a diverter pipe 702. The cleaning seat 701 is fixedly mounted on the mounting frame 5. Two rows of cleaning cotton rollers 703 are rotatably mounted on the cleaning seat 701. A plurality of nozzles 704 are fixedly mounted on the inner wall of the cleaning seat 701. The output end of the diverter pipe 702 is fixedly connected with the plurality of nozzles 704 at the same time. When in use, the diverter pipe 702 is connected to an external water supply source, and water is sprayed out through the nozzle 704. During the rotation of the blade head replaced from the pneumatic ultrasonic blade seat, the blade head is cleaned by the cleaning cotton roller 703 and water in the cleaning seat 701, and the cleaned sewage flows out and is discharged through both sides, thereby achieving the purpose of automatic cleaning after replacement.

[0030] like Fig.10 In the figure, a small hot air blower 801 is fixedly installed in the knife bit drying seat 8, and the output end of the small hot air blower 801 is fixedly connected to the knife bit drying seat 8. A cover ring 802 is rotatably installed on the knife bit drying seat 8. A plurality of holes are opened in a ring shape on the cover ring 802 and the spare knife seat 301 is movably clamped in the holes. A slot for ejecting the knife bit is opened at the bottom of the knife bit drying seat 8. When in use, the knife bit on the spare knife seat 301 is placed in the knife bit drying seat 8, and hot air is blown out by the small dryer to dry the knife bit in the knife bit drying seat 8. At the same time, the design of the cover ring 802 on the knife bit drying seat 8 not only improves the overall sealing effect, but also can serve the purpose of positioning the spare knife seat 301.

[0031] The specific working principle is that the spare cutter head is clamped in the spare cutter seat 301. During the cutter selection process, the high-speed motor can drive the cutter head placement rack 3 to rotate rapidly by utilizing the meshing action of the driving gear 201 and the inner gear ring of the cutter head placement rack 3. When the spare cutter seat 301 with the cutter head to be replaced passes the NFC sensor 303, the first electric telescopic rod 401 retracts to drive the connecting seat 404 to drop straight down. At the same time, the first connecting rod 405 rotates and the angle between the two first connecting rods 405 increases, and drives the brake seats 402 on both sides to rotate toward the cutter head driving seat 2, and the brake pads 406 contact the inner ring of the cutter head placement rack 3 to achieve deceleration. At this time, the first electric telescopic rod 401 continues to retract, and the brake seat 402 rotates outward and compresses the first spring 407 to lift the brake The friction force between the plate 406 and the cutter head placement rack 3 finally realizes the brake stop of the cutter head placement rack 3. After the cutter head is selected and placed at the lowest point of the cutter head driving seat 2, the connecting seat 404 descends and drives the pressure hammer 409 to descend through the second connecting rod 408. When the pressure hammer 409 contacts the limiting plate at the top of the third connecting rod 410, the cutter head placement rack 3 will stop completely. At this time, the pressure hammer 409 continues to move downward and presses the third connecting rod 410 downward while compressing the second spring 411. The third connecting rod 410 moves downward and drives the limiting clamping seat 412 to move downward. The limiting clamping seat 412 moves downward and drives the spare cutter seat 301 to rotate downward ninety degrees through the engagement with the roller 302 on the spare cutter seat 301, thereby achieving the purpose of changing the orientation of the spare cutter seat 301 to facilitate the subsequent cutter changing operation. When changing the tool, when the driving motor 601 drives the two ends of the tool head clamping seat 609 to be located directly below the pneumatic ultrasonic sawing tool seat 1 and the alternative tool seat, the second electric telescopic rod 602 retracts to drive the tool head clamping seat 609 to rise. During the rising process of the tool head clamping seat 609, the top rod 612 is pushed back by the mounting frame 5, and drives the limiting cone 610 to move downward to compress the third spring 611. Due to the cone-shaped design of the limiting cone 610 and the elastic effect of the fourth spring 614, the clamping rod 613 will be driven to retract. Thereby, the blade to be replaced on the spare blade holder 301 and the blade on the pneumatic ultrasonic sawing blade holder 1 are respectively placed at the two ends of the blade clamping seat 609. After completion, the second electric telescopic rod 602 pushes the blade clamping seat 609 to move down. According to the above principle, on the contrary, the clamping rod 613 extends out of the card slot on the blade to clamp the blades on both sides. At the same time, the driving motor 601 drives the blade clamping seat 609 to rotate 180 degrees and then rise, thereby achieving the purpose of automatic quick replacement of the blade; After the blade is replaced, the blade head is cleaned by the cleaning cotton roller 703 and water in the cleaning seat 701, and the brake assembly 4 is used to drive the spare blade seat 301 to return to its original position and allow the replaced blade head to enter the blade head drying seat 8, and hot air is blown out by a small dryer to dry the blade head in the blade head drying seat 8.
