[0002] During the assembly process of the bending transducer, the surface of the aluminum alloy structural part needs to be roughened so that the piezoelectric element and the aluminum alloy structural part are firmly bonded, so that the bending transducer has good acoustic performance. In general, the aluminum alloy structural parts of the bending transducer are usually small in diameter, thin in thickness and low in strength. Surface roughening using sandblasting is prone to deformation, which makes the vibrator prone to cracking during force curing. At present, in order to ensure that the components and structural parts are firmly bonded and the components do not crack, manual sandpaper is mostly used for surface roughening of aluminum alloy structural parts. During polishing, the structural part is pressed manually with the fingers to make its surface close to the sandpaper and polished along an 8-shaped trajectory for several circles until the surface of the structural part is roughened without reflection, the surface is flat and has no obvious deformation, and the surface roughening marks are clear and random. However, since operators cannot accurately control the grinding force, grinding trajectory and grinding times, the quality and consistency of the surface roughening effect of aluminum alloy structural parts are difficult to ensure. In addition, if large quantities of aluminum alloy structural parts are polished by manual sandpaper, the efficiency is low and the labor intensity is greatly increased.
