Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Example

[0022] Reference Figure 1-2 As shown, this embodiment provides a non-destructive cutting device for transducer piezoelectric ceramics, including a cutting assembly, a cutting platform 2, and a spraying assembly located on a support platform 1. The cutting assembly includes a cutter head 3 and a drive unit 4 for driving the cutter head 3 to rotate horizontally and / or move. The drive unit 4 provides rotational and translational force to the cutter head 3, enabling it to complete the cutting action. The cutting platform 2 is detachably connected to one side of the top surface of the support platform 1. The top surface of the cutting platform 2 is provided with a parallel cutting mold 5 and a baffle 6. The baffle 6 is used to prevent water splashing during cutting. The cutting mold 5 is provided with a workpiece placement groove 7 corresponding to the cutter head 3. The workpiece placement groove 7 is used to fix the piezoelectric ceramic and ensure its stability during cutting.

[0023] The spray assembly includes a water guide channel 8, a water collection tray 9, and a heat dissipation tray 10. The water guide channel 8 is evenly distributed on the top surface of the support platform 1, and its outlet is connected to the side of the support platform 1 away from the cutting platform 2. The outlet position of the water guide channel 8 is designed so that the sprayed water can flow a certain distance after falling onto the top surface of the support platform 1, allowing for heat dissipation. The water collection tray 9 and the heat dissipation tray 10 are arranged vertically around the side wall of the support platform 1, with the top edge of the water collection tray 9 higher than the top surface of the support platform 1. A water collection channel 11 is formed between the inner wall of the water collection tray 9 and the outer wall of the support platform 1, and a water return channel 12 is formed between the inner wall of the heat dissipation tray 10 and the outer wall of the support platform 1. The water collection channel 11 is connected to the water return channel 12 through a water guide pipe 13, and a water pump is provided at the end of the water return channel 12 away from the water guide pipe 13. The outlet of the water pump is connected to a nozzle 15 through a spray pipe 14, and the spray direction of the nozzle 15 is directed towards the cutter head 3.

[0024] In use, a suitable cutting platform 2 is selected according to the structural dimensions of the piezoelectric ceramic and fixed onto the support platform 1. Then, the piezoelectric ceramic is placed on the cutting platform 2. The drive unit 4 provides rotational and translational force to the cutter head 3, enabling the cutter head 3 to cut the piezoelectric ceramic. During cutting, the water pump is started in advance, sending the water in the heat sink 10 to the water spray pipe 14 and spraying it onto the cutter head 3 through the nozzle 15 to achieve spray cooling of the cutter head 3. The sprayed water on the cutter head 3 falls into the cutting mold 5 and the cutting platform 2 and then onto the top surface of the support platform 1. It then flows along the water guide groove 8 into the water collection channel 11 on the water collection plate 9, and finally enters the return water channel 12 on the heat sink 10 through the water guide pipe 13, realizing the recycling and reuse of water resources. During the recycling process, the sprayed water is cooled in the water guide groove 8, the water collection channel 11 and the return water channel 12, thereby ensuring the cooling effect of the sprayed water on the cutter head 3 during recycling.

[0025] A further optimized design features a bottom surface height of the return water channel 12 that gradually decreases from the end where the water guide pipe 13 is located to the end where the water pump is located. This provides more installation space for the water pump while also allowing for water circulation using gravity.

[0026] In a further optimized design, the bottom surface of the return water channel 12 is provided with corrugated edges evenly distributed along its length, and the corrugated edges are made of thermally conductive metal. The corrugated edges can increase the contact area between the return water channel 12 and the water, thereby improving the heat dissipation efficiency of the water.

[0027] In a further optimized design, a filter screen 16 is detachably connected to the top of the water pipe 13. The filter screen 16 can filter impurities in the water and prevent blockage of the pipe during water recycling.

[0028] In a further preferred embodiment, the drive unit 4 includes a drive housing 41. The top surface of the drive housing 41 has a guide groove, and a threaded rod 42 is installed within the guide groove. One end of the threaded rod 42 is connected to a first motor 43, and the other end is rotatably connected to the side wall of the guide groove. A nut seat on the threaded rod 42 is connected to a moving plate 44. A second motor 45 is fixedly connected to the top surface of the moving plate 44, and the output shaft of the second motor 45 is fixedly connected to the cutter head 3. A protective cover 17, corresponding to the cutter head 3, is fixedly connected to the top of the housing of the second motor 45. An adapter 18 is fixedly connected to the top surface of the protective cover 17. The inlet of the adapter 18 is fixedly connected to a spray pipe 14, and the outlet of the adapter 18 is fixedly connected to a nozzle 15. In use, the adapter 18 can fix the nozzle 15, so that the nozzle 15 can be aligned with the cutter head 3 to achieve spray cooling of the cutter head 3. The first motor 43 provides power for the horizontal movement of the cutter head 3, and the second motor 45 provides power for the rotation of the cutter head 3. The cooperation of the first motor 43 and the second motor 45 realizes the cutting of piezoelectric ceramics by the cutter head 3. During the cutting process, the protective cover 17 can prevent personnel from accidentally touching the cutter head 3 and causing personal injury.

[0029] In a further optimized design, the top surface of the cutting platform 2 is provided with a through groove 19 parallel to the baffle 6. A cutting mold 5 is detachably connected within the through groove 19, and the height of the cutting mold 5 is lower than the height of the baffle 6. The bottom surface of the workpiece placement groove 7 is provided with symmetrically arranged shims 20, the height of which is less than the depth of the workpiece placement groove 7. Vertical slits 21 are provided on the two side walls of the workpiece placement groove 7 parallel to the baffle 6. The two vertical slits 21 and the cutter head 3 are located on the same straight line, and the width of the vertical slits 21 is equal to the thickness of the cutter head 3. In use, the detachable connection between the through groove 19 and the cutting mold 5 allows for the replacement of different cutting molds 5 according to the different sizes of the piezoelectric ceramic. The shims 20 in the cutting mold 5 can elevate the piezoelectric ceramic, thereby preventing collision between the cutter head 3 and the cutting mold 5 when the cutter head 3 cuts the piezoelectric ceramic along the vertical slits 21.

[0030] In a further optimized design, a through hole is provided on the side of the cutting platform 2 near the outlet of the water guide trough 8, and the through hole is connected to the bottom surface of the through trough 19. The through hole facilitates the flow of spray water from the cutting platform 2 to the top surface of the supporting platform.

[0031] Therefore, the present invention provides a non-destructive cutting device for transducer piezoelectric ceramics with the above-mentioned structure. The fixing method is simple, effectively avoids water splashing, and enables water recycling.
