The main function of the pressing structure is to firmly press various components together to ensure the sealing, durability, and aesthetics of the case. Usually, the various components of the watch case are placed on the surface of the processing table and then pressed by a hydraulic device to ensure the tight connection of all components, thereby ensuring the assembly quality.

[0025] Refer to Figure 1 、 Figure 7 As shown in, a connecting component 5 is provided at the bottom of the telescopic end of the electric push rod 4. The connecting component 5 includes a mounting plate 501. The mounting plate 501 is fixedly connected to the outer periphery of the telescopic end of the electric push rod 4. The mounting plate 501 is used to mount the moving shaft 505 and the fixed shaft 502. The inside of the mounting plate 501 allows the moving shaft 505 and the fixed shaft 502 to move flexibly, providing an adjustment space. The moving shaft 505 is slidably connected inside the mounting plate 501. One end of the moving shaft 505 is rotatably connected to two rotating rods 503.

The opposite ends of the two fixed shafts 502 are slidably connected inside the telescopic end of the electric push rod 4. The movement of the moving shaft 505 can drive the rotation of the rotating rod 503, thereby driving the movement of the fixed shaft 502. A first spring 504 is sleeved on the outer periphery of the moving shaft 505. One end of the first spring 504 abuts against the outer periphery of the mounting plate 501, and the other end of the first spring 504 abuts against the other end of the moving shaft 505. The first spring 504 can push the moving shaft 505 to reset.,

[0026] Refer to Figure 1 、 Figure 8 and Figure 9 As shown in, a pressing component 7 is provided above the processing table 8. The pressing component 7 includes a mounting disc 701. The mounting disc 701 is arranged above the processing table 8. A pressing plate 703 is provided at the bottom of the mounting disc 701. A connecting sleeve 704 is fixedly connected to the top side of the pressing plate 703. The top of the connecting sleeve 704 is slidably connected inside the mounting disc 701. The mounting disc 701 is used to mount the pressing plate 703. The connecting sleeve 704 can connect the mounting disc 701 and the pressing plate 703 to each other. A plurality of uniformly distributed second springs 702 are fixedly connected to the top side of the connecting sleeve 704. The top ends of the second springs 702 are fixedly connected inside the mounting disc 701. A connecting shaft 6 is fixedly connected to the top side of the mounting disc 701. The connecting shaft 6 is slidably connected inside the telescopic end of the electric push rod 4. The connecting shaft 6 connects the mounting disc 701 and the telescopic end of the electric push rod 4 to each other inside the telescopic end of the electric push rod 4.

The plurality of second springs 702 can provide a buffering effect during the pressing process to ensure that the pressing plate 703 applies uniform and appropriate pressure.,

[0027] Refer to Figure 2, Figure 3 and Figure 6 , a lifting assembly 12 is arranged inside the processing table 8. The lifting assembly 12 includes a plurality of uniformly distributed connecting rods 1204. The plurality of connecting rods 1204 are respectively rotatably connected to the outer periphery of a plurality of mounting shafts 1102. The connecting rods 1204 serve to connect the mounting shafts 1102 and the support shafts 1203 to each other. Thus, when the mounting shafts 1102 move, they can drive the connecting rods 1204 to rotate, thereby driving the support shafts 1203 to move. One end of the plurality of connecting rods 1204 facing each other is rotatably connected to a support shaft 1203. A rotating shaft 1202 is slidably connected to the outer periphery of the support shaft 1203. The top end of the rotating shaft 1202 is fixedly connected to a support plate 1201. The support plate 1201 can drive the clock case to lift and rotate. The support plate 1201 can rotate with the rotating shaft 1202, thereby disturbing and driving the clock case on the top of the support plate 1201 to rotate. A guiding groove is formed inside the rotating shaft 1202. A guiding shaft 1205 is fixedly connected inside the processing table 8. One end of the guiding shaft 1205 close to the rotating shaft 1202 is slidably connected inside the guiding groove. When one end of the guiding shaft 1205 slides inside the guiding groove, the rotating shaft 1202 can rotate during the ascending process. The guiding groove is spiral. One end of the guiding shaft 1205 slides inside the guiding groove and the other end is fixed. When the rotating shaft 1202 moves upward along with the support shaft 1203, one end of the guiding shaft 1205 can drive the rotating shaft 1202 to rotate through sliding. The top end of the support shaft 1203 is fixedly connected to a limiting plate 1206. A limiting groove is formed inside the rotating shaft 1202. The limiting plate 1206 is slidably connected inside the limiting groove. The sliding of the limiting plate 1206 inside the limiting groove can limit the moving range of the rotating shaft 1202, ensuring that the rotating shaft 1202 does not exceed the specified working range.

[0028] Referring to Figure 1 and Figure 9 , two sliders 13 are fixedly connected inside the processing table 8. Two sliding grooves are formed inside the support rod 2. The sliders 13 are slidably connected inside the sliding grooves.

[0029] Working principle: When using this pressing structure to assemble the watch case, first select a pressing plate 703 with a suitable size according to the specific dimensions of the watch case. The pressing plate 703 is one of the key components in the entire pressing structure, and its size directly affects the pressure uniformity and effect on the watch case during the pressing process. Selecting a suitable pressing plate 703 can ensure uniform distribution of the pressing force and avoid excessive pressure on some areas, which may cause deformation or damage to the case. Then, press the moving shaft 505 into the inside of the mounting plate 501. During the movement of the moving shaft 505, it drives the rotation of the two rotating rods 503, thereby driving the two fixed shafts 502 to move away from each other. Subsequently, insert the connecting shaft 6 at the top of the mounting disc 701 into the telescopic end of the electric push rod 4 and release the moving shaft 505. Utilizing the elastic action of the first spring 504, it pushes the moving shaft 505 to reset and drives the rotation of the two rotating rods 503. During the rotation of the two rotating rods 503, they respectively drive the two fixed shafts 502 to move towards each other at one end close to the telescopic end of the electric push rod 4. After one end of the two fixed shafts 502 is inserted into the connecting shaft 6 and the telescopic end of the electric push rod 4, the installation of the pressing plate 703 is completed. Then, place the back case of the watch case at the rear of the watch case and invert the watch case and place it on the surface of the rubber pad 10 on the top of the processing table 8. At this time, the watch back case should be located at the bottom of the pressing plate 703. Then, start the servo motor 1104. The driving end of the servo motor 1104 starts to drive the rotation of the second gear 1113, and through the gear meshing of the first gear 1106 and the second gear 1113, the rotation is transmitted to the rotating shaft 1111. The rotation of the rotating shaft 1111 further drives the rotation of the turntable 1103. During the rotation of the turntable 1103, the multiple mounting shafts 1102 inside the turntable 1103 respectively drive the multiple clamping blocks 1105 to slide on the top of the processing table 8. The multiple clamping blocks 1105 move towards the watch case and clamp and fix the watch case, thereby preventing the watch case from shifting during the pressing process. When the clamping blocks 1105 clamp the watch case, the watch case applies pressure to the moving plate 1110, causing the moving plate 1110 to retract into the clamping block 1105 and squeeze the pressure sensor 1108. When the pressure received by the pressure sensor 1108 reaches a predetermined value, it can transmit an electrical signal to the controller 1107. After receiving the signal, the controller 1107 shuts down the operation of the servo motor 1104, thereby avoiding applying excessive clamping force and preventing damage to the watch case during the clamping process.

[0030] After the clamping and fixing of the clock case are completed, the electric push rod 4 can be started. The telescopic end of the electric push rod 4 extends to drive the pressing plate 703 at the bottom of the mounting plate 701 to move towards the clock case, thereby pressing the clock case. During the pressing process, multiple second springs 702 can disperse the pressure of the telescopic end of the electric push rod 4, so that the clock case is subjected to uniform pressure, ensuring the pressing effect of this structure. After the pressing is completed, the servo motor 1104 is started again. The driving end of the servo motor 1104 drives the turntable 1103 to rotate in the reverse direction, so that multiple mounting shafts 1102 respectively drive multiple clamping blocks 1105 to move away from the clock case. Through this action, the multiple clamping blocks 1105 will release the clock case. During the movement of the multiple mounting shafts 1102, they respectively drive multiple connecting rods 1204 to rotate. The rotation of the multiple connecting rods 1204 can drive the support shaft 1203 and the rotating shaft 1202 to move outside the processing table 8, so that the support shaft 1203 and the rotating shaft 1202 lift the clock case through the support plate 1201. During the movement of the rotating shaft 1202, the guide shaft 1205 slides inside the guide groove, so that the rotating shaft 1202 drives the clock case to rotate through the support plate 1201, facilitating manual inspection of the pressed clock case. Finally, after the inspection is completed, the worker can easily remove the clock case from the processing table 8 to complete the entire assembly process.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
