[0047] The present utility model provides a core-replaceable pressure-holding device, which is applicable to the application scenario of pressure-holding workpieces such as earphones, and can effectively solve the problem that the existing pressure-holding devices cannot quickly adapt to different products, resulting in a long R & D cycle and low production efficiency.

[0048] See Figure 1 and Figure 2 In this embodiment, the core-replaceable pressure-holding device includes a lower template 1, a lower core-replaceable body 2a, an upper template 3, an upper core-replaceable body 2b, and a spring module 4.

[0049] The lower core-replaceable body 2a is detachably installed on the lower template 1; the upper template 3 is snap-connected to the lower template 1; the upper core-replaceable body 2b is detachably installed below the upper template 3; the spring module 4 is located between the upper template 3 and the upper core-replaceable body 2b, and is used to drive the upper core-replaceable body 2b to cooperate with the lower core-replaceable body 2a to press the workpiece to be pressure-held downward.

[0050] Optionally, the core-replaceable body and the template are magnetically connected or fastened.

[0051] For the core-replaceable pressure-holding device provided in this embodiment, after the workpiece to be pressure-held is placed in the lower core-replaceable body 2a and the upper template 3 is buckled on the lower template 1, the upper core-replaceable body 2b can be driven by the elastic force of the spring module 4 to cooperate with the lower core-replaceable body 2a to press the workpiece to be pressure-held downward, thereby realizing the pressure-holding operation of the workpiece to be pressure-held; when the shape and structure of the workpiece to be pressure-held change, the lower template 1 and the upper template 3 can be reused, and only the lower core-replaceable body 2a and the upper core-replaceable body 2b need to be replaced.

[0052] Therefore, the core-replaceable pressure-holding device provided by the present utility model can effectively solve the problem that the existing pressure-holding devices cannot quickly adapt to different products, resulting in a long R & D cycle and low production efficiency.

[0053] In this embodiment, the lower replaceable core body 2a and the upper replaceable core body 2b both include a rigid member 201 and a flexible core body 202. An installation groove is provided on the rigid member 201; the flexible core body 202 is installed in the installation groove.

[0054] The flexible core body 202 is a component with a certain deformation ability. When the lower replaceable core body 2a and the upper replaceable core body 2b approach each other, the two flexible core bodies 202 respectively press the workpiece to be pressure-maintained from the top surface and the bottom surface of the workpiece to be pressure-maintained. Since the flexible core body 202 has good deformation ability, it can deform adaptively relative to the workpiece to be pressure-maintained, and then make good contact with the workpiece to be pressure-maintained.

[0055] At this time, if the workpiece to be pressure-maintained undergoes a change in structural dimensions, as long as the size of the new workpiece is still within the range that the flexible core body 202 can cover, no components need to be replaced. The flexible core body 202 can deform adaptively relative to the new workpiece by relying on its own deformation ability, and then make good contact with the new workpiece.

[0056] Of course, if the size of the new workpiece exceeds the range that the flexible core body 202 can cover, a new lower replaceable core body 2a and an upper replaceable core body 2b should be replaced.

[0057] Furthermore, the flexible core body 202 is a high-density sponge, a silica gel block or an airbag. Among them, the airbag is communicated with an air charging and discharging nozzle. Using the airbag as the flexible core body 202, it can not only deform adaptively relative to the new workpiece, but also control the air pressure of the airbag through the air charging and discharging nozzle, thereby controlling the pressure-maintaining pressure.

[0058] Optionally, in some other embodiments, the lower replaceable core body 2a and the upper replaceable core body 2b are both rigid members 201; the lower replaceable core body 2a is provided with a lower workpiece groove adapted to the bottom surface of the workpiece to be pressure-maintained, and the upper replaceable core body 2b is provided with an upper workpiece groove adapted to the top surface of the workpiece to be pressure-maintained. At this time, when the shape and structure of the workpiece to be pressure-maintained change, both the lower replaceable core body 2a and the upper replaceable core body 2b need to be replaced as a whole.

[0059] In this embodiment, the lower template 1 is provided with a plurality of positioning holes 101, and the upper template 3 is provided with positioning columns 301 corresponding to the positions of each of the positioning holes 101, so as to complete the vertical alignment between the two modules.

[0060] The upper template 3 is provided with threaded holes 302. The replaceable core pressure-holding device further includes a connecting bolt 5 and an adjusting bolt 6. The connecting bolt 5 slidably passes through the upper replaceable core body 2b from bottom to top and is threadedly connected to the lower end of the threaded hole 302. The adjusting bolt 6 is threadedly screwed into the threaded hole 302 from the upper end of the threaded hole 302, and the bottom surface of the adjusting bolt 6 abuts against the connecting bolt 5. It can be understood that by turning the adjusting bolt 6, the maximum depth dimension of the connecting bolt 5 entering the threaded hole 302 can be adjusted, and thus the elastic force of the spring module 4 can be adjusted.

[0061] In summary, the replaceable core pressure-holding device provided in this embodiment has at least the following advantages:

[0062] ① Quick adaptation ability: By replacing the lower replaceable core body 2a and the upper replaceable core body 2b, this device can quickly adapt to workpieces to be pressure-held with different shapes and sizes, greatly shortening the preparation time for product research and development and production, and improving production efficiency.

[0063] ② High flexibility: The lower replaceable core body 2a and the upper replaceable core body 2b of this device are both detachable designs, enabling the device to flexibly respond to various changes in product structures without the need to replace the entire module, reducing the maintenance cost.

[0064] ③ Adaptive deformation: With the design of the flexible core body 202, this device can perform adaptive deformation on the workpiece to be pressure-held, ensuring the uniformity and stability of pressure-holding and improving the quality of the product.

[0065] ④ Precise control: Through the cooperation of the adjusting bolt 6 and the connecting bolt 5, the elastic force of the spring module 4 can be precisely controlled, thereby realizing fine adjustment of the pressure-holding pressure to meet the pressure-holding requirements of different workpieces.

[0066] ⑤ Accurate positioning: The design of the positioning holes 101 on the lower template 1 and the positioning posts 301 on the upper template 3 ensures accurate alignment between the upper and lower modules, improving the accuracy and efficiency of operation.

[0067] ⑥ Easy maintenance: Due to the replaceability of the lower replaceable core body 2a and the upper replaceable core body 2b, the maintenance and cleaning of the device become simpler and faster.

[0068] ⑦ Wide applicability: This device is applicable to the pressure-holding of various types of workpieces, especially for those workpieces with complex shapes and structures and frequent size changes, having significant advantages.

[0069] In summary, the replaceable core pressure-holding device provided in this embodiment not only solves the problem that the existing pressure-holding devices cannot quickly adapt to different products, but also improves production efficiency and product quality, having broad application prospects and economic benefits.

[0070] Finally, it should be noted that although the above embodiments have been described in the text of the specification and the drawings of this application, the patent protection scope of this application cannot be limited thereby. Any technical solutions obtained by equivalent structure or equivalent process substitution or modification based on the substantial concept of this application and using the content recorded in the text of the specification and the drawings of this application, as well as directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, etc., are all included in the patent protection scope of this application.
