[0037] The present utility model provides a pneumatic riveting machine 100. Specifically, please refer to Figures 1 to 2, in this embodiment, the pneumatic riveting machine 100 includes a base 1, a riveting structure 2, a riveting driving structure 3, a limiting structure 4 and a carrier structure 5; the riveting structure 2 is movably arranged on the base 1 and has at least a moving stroke in the up and down direction of the base 1; the riveting driving structure 3 includes a riveting cylinder drivingly connected to the riveting structure 2, and the riveting cylinder is used to drive the riveting structure 2 to move in the up and down direction of the base 1; the limiting structure 4 is arranged on the base 1 and is located below the riveting structure 2, and the limiting structure 4 defines a limiting reference; the carrier structure 5 is arranged corresponding to the limiting reference so that the center of the product placed on the carrier structure 5 can be coaxially arranged with the center of the riveting structure 2.

[0038] In this embodiment, the riveting driving structure 3 can drive the riveting structure 2 to move in the up and down direction of the base 1 to approach and move away from the product to be riveted; the limiting structure 4 is used to define a limiting reference, and this limiting reference is used to define the placement position of the carrier structure 5 so that after the product to be riveted is placed on the carrier structure 5, the center of the product placed on the carrier structure 5 can be coaxially arranged with the center of the riveting structure 2. When the riveting driving structure 3 drives the riveting structure 2 to move in the up and down direction of the base 1, the riveting structure 2 is more accurately aligned with the product and is not easily offset, so the riveting effect is better.

[0039] It should be noted that, in combination with Figure 1 and Figure 2 As shown, when the pneumatic riveting machine 100 is working normally, the base 1 is in a horizontal state, and the transverse and longitudinal directions of the base 1 are two directions perpendicular to each other on the horizontal plane of the base 1. For example, the transverse direction of the base 1 can refer to the left and right direction along the base 1, and the longitudinal direction of the base 1 refers to the front and back direction along the base 1. Accordingly, the descriptions of the orientations in the present invention can all be referred to this.

[0040] Among them, in combination with Figure 1 and Figure 3As shown, the riveting structure 2 includes a riveting mounting plate 21 and at least two riveting blocks 22. The riveting mounting plate 21 is arranged in a substantially flat plate shape and is connected to the riveting driving structure 3. At least two of the riveting blocks 22 are arranged at intervals at the bottom of the riveting mounting plate 21. The riveting center formed by enclosing at least two of the riveting blocks 22 is coaxially arranged with the product center on the carrier structure 5 in the up and down direction of the base 1. By driving the riveting mounting plate 21 to move in the up and down direction of the base 1 through the riveting driving structure 3, driving the two riveting blocks 22 to move simultaneously in the up and down direction of the base 1, and pressing the two riveting blocks 22 against both sides of the riveting ring at the same time, the force on the riveting ring is more balanced, so that the position of the riveting ring is more correct during riveting, and thus the riveting effect is better.

[0041] Furthermore, as shown in combination with Figure 1 and Figure 2 the riveting driving structure 3 includes a first support plate 31 and a second support plate 32 arranged at intervals in the up and down direction, and a riveting driver 33. The first support plate 31 is located above the second support plate 32 and is connected to the base 1. The second support plate 32 has a moving stroke in the up and down direction of the base 1. Both the first support plate 31 and the second support plate 32 are arranged in a flat plate shape. Preferably, the first support plate 31 and the second support plate 32 have the same shape. The riveting driver 33 is arranged on the first support plate 31 and is connected to the second support plate 32. The riveting mounting plate 21 is arranged at the bottom of the second support plate 32. The riveting driver 33 can be set as a driving cylinder. By driving the second support plate 32 to move in the up and down direction of the base 1 through the riveting driver 33, driving the riveting mounting plate 21 to move in the up and down direction of the base 1, the two riveting blocks 22 can be riveted on the riveting ring, with more accurate alignment and balanced force, thereby improving the riveting effect.

[0042] Furthermore, as shown in Figure 1As shown, the riveting driving structure 3 further includes a plurality of support columns 34, and a plurality of guide sleeves 35 slidably sleeved on the plurality of support columns 34 one by one. The plurality of support columns 34 connect the base 1 and the first support plate 31. Each support column 34 is generally cylindrical, and the plurality of support columns 34 all extend along the up and down direction of the base 1. The first support plate 31 is generally square. Preferably, four support columns 34 are provided, and the four support columns 34 are arranged corresponding to the four corners of the first support plate 31, so that the fixation of the first support plate 31 is more stable, and an empty space can be defined between the first support plate 31 and the base 1 to facilitate the movement of the riveting block 22. The plurality of guide sleeves 35 are arranged on the second support plate 32. The riveting driver 33 drives the second support plate 32 to move along the up and down direction of the base 1, driving the plurality of guide sleeves 35 to slide up and down along the corresponding plurality of support columns 34. Under the guiding movement of the plurality of guide cylinders and the plurality of support columns 34, the second support plate 32 is more stable when moving along the up and down direction of the base 1. Therefore, the two riveting blocks 22 are not easily shaken when moving along the up and down direction of the base 1. When pressed against the riveting ring, the riveting angle is more accurate, and the product to be riveted (such as the shell) can be better protected.

[0043] Moreover, as shown in combination with Figure 2 and Figure 3 the riveting driving structure 3 further includes a plurality of elastic telescopic members 36. The plurality of elastic telescopic members 36 are sleeved on the outer sides of the plurality of support columns 34 one by one and abut between the corresponding guide sleeves 35 and the base 1. When the riveting block 22 presses the product through the plurality of elastic telescopic members 36, a buffer is formed, and there will be no hard contact, which can effectively release the overshoot pressure and can also better protect the riveting ring. The elastic telescopic member 36 can be set as a telescopic spring.

[0044] For the limiting structure 4, as shown in combination with Figure 1 and Figure 2As shown, the limiting structure 4 includes a limiting block 41. The limiting block 41 has a first limiting arm 411 extending along the transverse direction of the base 1 and a second limiting arm 413 extending along the longitudinal direction of the base 1. The first limiting arm 411 and the second limiting arm 413 are cross - arranged. The first limiting arm 411, the second limiting arm 413, and the intersection of the first limiting arm 411 and the second limiting arm 413 together form the limiting reference. Among them, on the side of the base 1 facing the second support block, a support platform is formed. The support platform is horizontally arranged. The limiting block 41 is arranged on the support platform. The position of the bearing structure can be limited by the first limiting arm 411 and the second limiting arm 413 to ensure the accurate position of the bearing structure, thereby ensuring the accurate position of the product to be riveted placed on the bearing structure.

[0045] Furthermore, the carrier structure 5 includes a bearing table 51. The bearing table 51 abuts against the first limiting arm 411 and the second limiting arm 413, or the bearing table 51 has a corner adapted to the intersection of the first limiting arm 411 and the second limiting arm 413. The bearing table 51 is fixed on the support platform by the limitation of the first limiting arm 411 and the second limiting arm 413, or the bearing table 51 is limited by the corner between the first limiting arm 411 and the second limiting arm 413.

[0046] Preferably, one end of the first limiting arm 411 and the second limiting arm 413 are connected, and the first limiting arm 411 and the second limiting arm 413 are perpendicularly arranged. According to the different shapes of the products, different bearing tables 51 can be correspondingly manufactured to better support and fix the products. Therefore, when corresponding to different bearing tables 51, the limiting methods of the bearing table 51 are slightly different, but it can be ensured that under the action of the first limiting arm 411 and the second limiting arm 413, the bearing table 51 can be limited and fixed on the support platform, and the center of the product placed on the bearing table 51 is coaxial with the center formed by the two riveting blocks 22 to ensure the accurate riveting angle.

[0047] Among them, such as Figure 3As shown, the vehicle structure 5 further includes a plurality of positioning portions 52 protruding from the bearing table 51. The plurality of positioning portions 52 are adapted to be positioned and cooperate with a plurality of mating portions on the product, and the product can be restricted on the bearing table 51 through the plurality of positioning portions 52. The positioning portion 52 can be set as a plurality of positioning protrusions, and the product is fixed on the bearing table 51 by clamping the plurality of positioning protrusions into corresponding plurality of positioning holes. According to different products, there are also various setting methods for the positioning portion 52. When corresponding to different products, different bearing tables 51 can be correspondingly replaced, with a wider application range, lower replacement cost, and improved overall adaptation work efficiency.

[0048] Moreover, as Figure 2 shown, a first long hole 412 is provided on the first limiting arm 411. The first long hole 412 extends along the longitudinal direction of the base 1, and a second long hole corresponding to the first long hole 412 is provided on the base 1. The pneumatic riveting machine 100 further includes a first connecting member, and the first connecting member passes through the first long hole 412 and the second long hole to connect and fix the first limiting arm 411 and the base 1. The first connecting member can be set as a screw, a bolt or a pin, etc. By passing the first connecting member through different positions of the first long hole 412 or the second long hole, the position of the first limiting arm 411 along the longitudinal direction of the base 1 can be adjusted, so that the first limiting arm 411 can better adapt to the limiting requirements of different bearing tables 51.

[0049] Similarly, as Figure 2 shown, a third long hole 414 is provided on the second limiting arm 413. The third long hole 414 extends along the transverse direction of the base 1, and a fourth long hole corresponding to the third long hole 414 is provided on the base 1. The pneumatic riveting machine 100 further includes a second connecting member, and the second connecting member passes through the third long hole 414 and the fourth long hole to connect and fix the second limiting arm 413 and the base 1. The second connecting member can be set as a screw, a bolt or a pin, etc. By passing the second connecting member through different positions of the third long hole 414 or the fourth long hole, the position of the second limiting arm 413 along the transverse direction of the base 1 can be adjusted, so that the second limiting arm 413 can better adapt to the limiting requirements of different bearing tables 51.

[0050] In an embodiment, two limiting bosses 6 can also protrude from the base 1. The two limiting bosses 6 are used to limit the downward stroke of the second support plate 32, avoiding excessive downward movement of the second support plate 32, which may cause excessive riveting amount and product deformation, thereby better ensuring the riveting effect.

[0051] In one embodiment, the pneumatic riveting machine 100 further includes a control device and a pneumatic switch 7. The control device is electrically connected to both the pneumatic switch 7 and the riveting driver 33. Among them, there are two pneumatic switches 7. When the two pneumatic switches 7 are started simultaneously, the control device can control the riveting driver 33 to start working. When only one pneumatic switch 7 is started or no pneumatic switch 7 is started, the control device controls the riveting driver 33 not to work, which can better ensure work safety and avoid riveting danger. Moreover, the riveting driver 33 is a driving cylinder with pneumatic control design, which can stably control the lower static pressure, making the pressure received at multiple riveting positions relatively stable. Therefore, the riveting effect is better.

[0052] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly.
