For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples.

Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or device comprising the element.

[0023] like Figure 1 As shown, this embodiment discloses a pressing device, including: a frame 100, a telescopic mechanism 200, a pressing table 300, a pressure sensor 400, and a pressing arm mechanism 500;

[0024] The frame 100 is fixedly mounted on the external structure, and the frame 100 can provide mounting and connection positions for various components.

[0025] The telescopic mechanism 200 is mounted on the frame 100, and its telescopic direction is configured in the height direction. The telescopic mechanism 200 is used to drive the pressing table 300 downward, thereby realizing the pressing operation. In this embodiment, the telescopic mechanism 200 includes a power component with linear telescopic capability, such as a servo electric cylinder. In this embodiment, the telescopic mechanism 200 is preferably a servo electric cylinder, which is mounted on the frame 100. The output end of the servo electric cylinder is detachably connected to the pressing arm of the pressing arm mechanism 500. The detachable connection method can refer to the prior art. This connection method facilitates quick assembly and disassembly of the pressing arm.

[0026] like Figure 2 As shown, the pressure table 300 is slidably mounted on the frame 100. The sliding direction of the pressure table 300 is configured to be the extension direction of the telescopic mechanism, i.e., the height direction. The pressure table 300 is provided with multiple second guide posts 310. The second guide posts 310 slide upward through the frame 100. The axial direction of the second guide posts 310 is parallel to the extension direction of the telescopic mechanism. The pressure table 300 can slide up and down relative to the frame 100 through the second guide posts 310. Driven by the telescopic mechanism 200, the pressure table 300 can press down on the workpiece (not shown).

[0027] like Figure 3As shown, in this embodiment, a pressure block 320 is provided on the side of the pressure table 300 away from the telescopic mechanism 200, that is, on the lower side of the pressure table 300. The pressure block 320 is used to contact the workpiece and press it downward. A second elastic member 330 is provided between the pressure block 320 and the pressure table 300. The telescopic direction of the second elastic member 330 is configured to be the telescopic direction of the telescopic mechanism. When the pressure block 320 contacts the workpiece, as the pressure table 300 continues to move downward, the second elastic member 330 is compressed, so that the pressure block 320 can elastically press the workpiece to avoid structural damage.

[0028] like Figure 3 As shown, in some preferred embodiments, a third guide post 340 is provided on the pressure block 320. The axial direction of the third guide post 340 is aligned with the telescopic direction of the telescopic mechanism. The third guide post 340 passes upward through the pressure table 300 and can slide with the pressure table 300. The second elastic element 330 is configured as a spring and is coaxially sleeved on the third guide post 340. Both ends of the second elastic element 330 abut against the pressure block 320 and the pressure table 300, respectively. In this embodiment, by providing the third guide post 340, the pressure block 320 and the pressure table 300 can only slide relative to each other in the height direction, thereby ensuring the pressing accuracy.

[0029] like Figure 4 As shown, in some preferred embodiments, a plurality of pressure blocks 320 are provided on the lower side of the pressure table 300. The plurality of pressure blocks 320 are distributed at different positions on the lower side of the pressure table 300, and at least one second elastic element 330 is provided between each pressure block 320 and the pressure table 300. In this embodiment, by providing a plurality of pressure blocks 320, compatible elastic pressing can be performed on various types of workpieces. The workpiece is pressed using an independent elastic pressure block 320 method, which can avoid the workpiece being damaged due to unevenness of the pressing surface.

[0030] like Figure 3 As shown, a pressure sensor 400 is provided on one surface of the press table 300 opposite to the telescopic mechanism 200. That is, a pressure sensor 400 is provided on the upper surface of the press table 300. The pressure sensor 400 is used to measure the pressing pressure.

[0031] like Figure 2 and Figure 3 As shown, the pressure arm mechanism 500 includes a pressure arm 510, a pressure head assembly 520, a sliding plate 530, a first guide post 540, and a first elastic element 550.

[0032] like Figure 3 As shown, the upper end of the pressure arm 510 is detachably connected to the telescopic end of the telescopic mechanism 200, the axial direction of the pressure arm 510 is consistent with the telescopic direction of the telescopic mechanism, and the lower end of the pressure arm 510 is provided with a pressure head assembly 520.

[0033] like Figure 3 As shown, the sliding plate 530 is slidably disposed on the pressure arm 510 and is located above the pressure head assembly 520. The two ends of the first guide post 540 are respectively connected to the sliding plate 530 and the pressure table 300. The first elastic element 550 (e.g., a spring) is coaxially sleeved on the pressure arm 510, and the two ends of the first elastic element 550 abut against the pressure head assembly 520 and the sliding plate 530 respectively. The extension and retraction direction of the first elastic element 550 is configured to be the axial direction of the pressure arm 510. The elastic force of the first elastic element 550 can make the sliding plate 530 have an upward tendency, thereby making the sliding plate 530 lift the pressure table 300 through the first guide post 540. The pressure sensor 400 on the pressure table 300 can contact the pressure head assembly 520.

[0034] In this embodiment, by setting the first elastic element 550 to balance the weight of the pressure table 300, the pressure sensor 400 on the pressure table 300 can always maintain contact with the pressure head assembly 520. Even when the required pressing force is small, the pressure sensor 400 can still obtain the real pressing force output by the telescopic mechanism 200.

[0035] like Figure 3 As shown, the lower end of the first guide post 540 is fixedly connected to the pressure table 300, and the upper end of the first guide post 540 is connected to the sliding plate 530. In this embodiment, the first guide post 540 includes a post body 541 and an adjusting nut 542. The post body 541 is integrally formed from a large-diameter section and a small-diameter section, and a first shoulder surface 543 is formed between the large-diameter section and the small-diameter section. The small-diameter section of the post body 541 slides upward along its axial direction through the sliding plate 530. The adjusting nut 542 is threadedly connected to the small-diameter section of the post body 541. The axial positioning of the sliding plate 530 on the post body 541 is achieved through the first shoulder surface 543 and the adjusting nut 542. In this embodiment, the preload of the first elastic element 550 can be adjusted by turning the position of the adjusting nut 542.

[0036] like Figure 3As shown, the pressure head assembly 520 includes a first threaded sleeve 521, a second threaded sleeve 522, and a third elastic element 523. The first threaded sleeve 521 is coaxially and slidably sleeved on the pressure arm 510. The pressure arm 510 is provided with a second shoulder surface 511, which can abut against the inner top surface of the first threaded sleeve 521 in the axial direction of the pressure arm 510. The lower end of the first elastic element 550 abuts against the upper top surface of the first threaded sleeve 521, thereby making the inner top surface of the first threaded sleeve 521 and the second shoulder surface 511 fit tightly together. At least part of the second threaded sleeve 522 is threadedly connected inside the first threaded sleeve 521. The second threaded sleeve 522 and the first threaded sleeve 521 are coaxially arranged. When the first threaded sleeve 521 is screwed upward, the overall length of the second threaded sleeve 522 and the first threaded sleeve 521 can be shortened. The lower surface of the second threaded sleeve 522 can contact the pressure sensor 400 on the pressure table 300. The third elastic element 523 (e.g., a spring) is coaxially disposed inside the second threaded sleeve 522. The upper end of the third elastic element 523 abuts against the lower end face of the pressure arm 510, and the lower end of the third elastic element 523 abuts against the inner bottom surface of the second threaded sleeve 522. The extension and retraction direction of the third elastic element 523 is configured to be the axial direction of the pressure arm 510.

[0037] In this embodiment, the third elastic element 523 can prevent the pressure arm 510 from damaging the pressure sensor 400, while the second threaded sleeve 522 can be screwed upward into the first threaded sleeve 521, thereby adjusting the preload of the third elastic element 523. In some preferred embodiments, the elastic force of the third elastic element 523 is greater than the elastic force of the first elastic element 550.

[0038] like Figure 3 As shown, in some preferred embodiments, the pressure arm 510 is provided with a third shoulder surface 512. The projection of the third shoulder surface 512 and the upper end surface of the second threaded sleeve 522 on the axial direction of the pressure arm 510 overlaps. When the pressure arm 510 is pressed down to a certain stroke, the third shoulder surface 512 on the pressure arm 510 is pressed down and abuts against the upper end surface of the first threaded sleeve 521, so that the pressure arm 510 and the telescopic mechanism 200 are subjected to the reaction force of the workpiece, which can give feedback to the telescopic mechanism 200 that the press-fitting is in place.

[0039] like Figure 4 As shown, in some preferred embodiments, an overload ring 600 is coaxially fixed on the pressure arm 510, and an overload ring sensor 700 is provided on the pressure table 300. The overload ring sensor 700 corresponds to the overload ring 600 along the radial direction of the overload ring 600. When the pressure arm 510 moves down, the overload ring 600 moves down with the pressure arm 510. When the overload ring 600 moves down beyond a predetermined range, the overload ring sensor 700 loses its signal, and can then provide feedback to the external system that the pressure arm 510 has been pressed into place or over-pressed.

[0040] The working principle of the pressing device in this embodiment is as follows:

[0041] In the initial state, the first elastic element 550 has the tendency to drive the sliding plate 530 to move upward. The sliding plate 530 drives the pressure sensor 400 on the pressure table 300 to the position of contacting the second threaded sleeve 522 through the first guide post 540.

[0042] When it is necessary to press the workpiece, the telescopic mechanism 200 drives the pressure arm 510 to move down. The lower end face of the pressure arm 510 is supported by the third elastic element 523 between it and the second threaded sleeve 522. The pressure arm 510 drives the second threaded sleeve 522 and the first threaded sleeve 521 to move down together. The second threaded sleeve 522 acts on the pressure sensor 400, and at the same time drives the pressure table 300 to slide down. The pressure block 320 on the lower side of the pressure table 300 contacts the pressing point on the workpiece and applies elastic pressure to the workpiece, thereby realizing the pressing of the workpiece.

[0043] The first elastic element 550 keeps the pressure sensor 400 in contact with the second threaded sleeve 522, and the pressure sensor 400 monitors the pressing force in real time; the second elastic element 330 enables the pressure block 320 to make elastic contact with the workpiece; the third elastic element 523 prevents the second threaded sleeve 522 from damaging the pressure sensor 400.

[0044] The above description is only a specific embodiment of the present application. Those skilled in the art will clearly understand that for the convenience and brevity of description, the specific working processes of the systems, modules and units described above can refer to the corresponding processes in the aforementioned method embodiments, and will not be repeated here. It should be understood that the scope of protection of the present application is not limited thereto. Any person skilled in the art can easily think of various equivalent modifications or replacements within the technical scope disclosed in the present application, and these modifications or replacements should be included in the scope of protection of the present application.
