[0023] To make the above objects, features, and advantages of the present application more apparent and understandable, the following describes the specific embodiments of the present application in detail with reference to the accompanying drawings. Many specific details are set forth in the following description to facilitate a thorough understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0024] Referring to Figures 1 to 3 , this embodiment provides a pneumatic pressing device for the sheet metal radiation surface of a low-frequency oscillator, including: a bakelite base 100 and a pressing mechanism 200.

[0025] The following introduces the specific structure of the pneumatic pressing device for the sheet metal radiation surface of the low-frequency oscillator.

[0026] The bakelite base 100 is provided with an oscillator receiving groove 110. A support tooling 120 is arranged on the bakelite base 100. A positioning groove 121 is formed on the surface of the support tooling 120 facing away from the bakelite base 100. First pads 122 are arranged at the four corners of the inner bottom surface of the positioning groove 121. A second pad 123 is arranged in the middle of the inner bottom surface of the positioning groove 121. A through groove 124 is longitudinally formed in the second pad 123, and the through groove 124 communicates with the oscillator receiving groove 110; the pressing mechanism 200 includes: a lower pressing plate 210, and the lower pressing plate 210 is movably arranged above the support tooling 120.

[0027] When the pneumatic pressing device for the sheet metal radiation surface of the low-frequency oscillator is working, the operator passes the oscillator body through the through groove 124 of the support tooling 120 and places it in the oscillator receiving groove 110 of the bakelite base 100; subsequently, the operator places the sheet metal radiation surface on the oscillator body, where the slot of the sheet metal radiation surface is aligned with the buckle of the oscillator body. The pressing mechanism 200 is started, and the lower pressing plate 210 moves downward. The lower pressing plate 210 drives the sheet metal radiation surface to press downward, so that the buckle of the oscillator body passes through the slot of the sheet metal radiation surface to achieve assembly.

[0028] By arranging the support tooling 120 on the bakelite base 100 and forming the positioning groove 121 on the support tooling 120, and cooperating with the design of the first pads 122 and the second pads 123, this device can achieve precise positioning and stable support for the oscillator body; moreover, the use of the first pads 122 and the second pads 123 not only provides stable support but also plays a role in buffering and protection; the lower pressing plate 210 can apply force to the sheet metal radiation surface evenly and controllably, thereby ensuring the quality of the low-frequency oscillator pressing assembly.

[0029] Referring to Figures 1 to 3, in some embodiments, the pressing mechanism 200 further includes: a pressing cylinder 220 and a lifting seat 230. The pressing cylinder 220 is disposed above the supporting tooling 120, and the pressing cylinder 220 is in transmission connection with the lifting seat 230. In this way, by driving the lower pressing plate 210 in a pneumatic manner, it can ensure that the force applied by the lower pressing plate 210 is uniform and controllable. The pressing cylinder 220 has the characteristics of fast response speed and stable force, and can better meet the accuracy and efficiency requirements for pressing the radiating surface of the low-frequency oscillator sheet metal.

[0030] Refer to Figures 1 to 3 , in some embodiments, the pressing mechanism 200 further includes: a plurality of sliding rods 240. The sliding rods 240 are provided on the bakelite base 100, and a plurality of flange linear bearings are embedded in the lifting seat 230. The flange linear bearings are sleeved on the sliding rods 240. In this way, the lifting seat 230 can slide up and down along the sliding rods 240, enabling the lifting seat 230 to slide smoothly.

[0031] Refer to Figures 1 to 3 , in some embodiments, the lower pressing plate 210 is provided with a plurality of first mounting holes 211, and the lifting seat 230 is provided with a plurality of second mounting holes.

[0032] In this embodiment, both the first mounting holes 211 and the second mounting holes are circular holes.

[0033] Refer to Figures 1 to 3 , in some embodiments, the surface of the lower pressing plate 210 facing the supporting tooling 120 is provided with a plurality of avoiding grooves 212. When the pressing block applies force to the radiating surface of the sheet metal, the part of the oscillator body passing through the radiating surface of the sheet metal can enter the avoiding grooves 212 to avoid interference and affect the pressing process.

[0034] Refer to Figures 1 to 3 , in some embodiments, the supporting tooling 120 is provided with a plurality of third mounting holes 125, and the bakelite base 100 is provided with a plurality of fourth mounting holes. The fourth mounting holes correspond to the third mounting holes 125 one by one. In this way, through the cooperation of the third mounting holes 125 and the fourth mounting holes, fixing members such as bolts can pass through the third mounting holes 125 and the fourth mounting holes to achieve stable connection between the supporting tooling 120 and the bakelite base 100.

[0035] In this embodiment, both the third mounting holes 125 and the fourth mounting holes are circular holes.
