[0027] Example

[0028] like Figure 1-8 As shown, this utility model discloses a tooling for manufacturing an ultrasonic transducer, including a support frame and a pressing assembly fixedly installed on the support frame. The support frame consists of a base plate 1, a support plate 2, and an upper pressure plate 3. Four sets of first linear guide rods 4 are vertically arranged above the base plate 1. One end of the first linear guide rod 4 is fixedly connected to the base plate 1, and the other end is fixedly connected to the upper pressure plate 3 to ensure the structural strength of the overall tooling. The support plate 2 is connected to the first linear guide rod 4 through a first linear bearing 5. The first linear bearing 5 allows the support plate 2 to rise and fall along the first linear guide rod 4.

[0029] The pressing assembly includes a handwheel 6, a pressing structure, and a universal pressing head 7. The pressing structure consists of an adjusting screw 8 and an adjusting nut 9. The adjusting nut 9 is fixed on the upper pressing plate 3. The adjusting screw is connected to the adjusting nut 9. The top end of the adjusting screw is connected to the handwheel 6, and its bottom end is connected to the universal pressing head 7. The bottom of the universal pressing head 7 is connected to the top of the pressing block 13.

[0030] A weighing sensor 10 is installed on the base plate 1, and the weighing sensor 10 is connected to an external display. The bottom of the tray 2 is connected to the weighing sensor 10 via a buffer spring 11. The upper surface of the tray 2 is provided with a limit stop 16 and four sets of second linear guide rods 12. A pressure block 13 is sleeved on the second linear guide rod 12. The pressure block 13 is connected to the second linear guide rod 12 through a second linear bearing 14. A second pressure head 15 is provided at the bottom of the pressure block 13. A conical limit pin 17 is provided at the bottom of the limit stop 16. The limit stop 16 is positioned by the conical limit pin 17 and the pin hole on the tray 2, and is fixed to the tray 2 by screws 18 to prevent misalignment of the assembly materials and ensure assembly accuracy.

[0031] Therefore, the present invention adopts a method for using an ultrasonic transducer manufacturing fixture with the above structure: first, the transducer assembly is placed on the tray 2 and fixed by the limiting post and the limiting block 16.

[0032] Rotating handwheel 6 drives the adjusting screw downwards, and universal pressure head 7 drives pressure block 13 to uniformly press down on each bonding layer of the transducer along the second straight guide rod 12. The pressure value is transmitted to the weighing sensor 10 through buffer spring 11, and the display provides real-time feedback of the pressure value.

[0033] After bonding is complete, rotate handwheel 6 in the opposite direction to release the pressure and remove the transducer.
