Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

Therefore, they should not be construed as limitations on this utility model.

[0032] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] Please see Figure 1-4 A gripping device for a seaming machine includes a pressing mechanism 4 and an adjusting mechanism 5. Both the pressing mechanism 4 and the adjusting mechanism 5 are installed on the upper surface of the seaming machine body 1. The pressing mechanism 4 includes an L-shaped plate 401 fixedly installed with the machine body 1 and a plurality of pressure rollers 402 suspended on the inner wall of the L-shaped plate 401.

[0034] The adjusting mechanism 5 includes: a first mounting plate 502 with a second sliding groove (not shown in the figure); a second mounting plate 503 with a first sliding groove 5031, slidably mounted on the first mounting plate 502; a second spring 507, disposed between the first mounting plate 502 and the second mounting plate 503, for providing elastic force for the sliding of the second mounting plate 503; multiple sliding members 504, sliding on the first mounting plate 502 and the second mounting plate 503 through the first sliding groove 5031 and the second sliding groove, with a roller 5045 rotatably connected to their bottom. The rotational design of the roller 5045 makes the material slide more smoothly and with less friction when it is bitten; and an adjusting screw 506, threadedly connected to the second mounting plate 503, with its end acting on the sliding member 504, for adjusting the position of the sliding member 504 on the second mounting plate 503.

[0035] It should be noted that many multi-functional seaming machines have appeared on the market, most of which include a flat seaming mechanism 2 and a circular arc seaming mechanism 3. In view of the problem that the shape of the stop block of the seaming machine clamping device is fixed in the existing technology, it cannot act on curved plates and is only applicable to the flat seaming mechanism 2, and cannot meet the material stopping requirements of the circular arc seaming mechanism 3, this device solves the above problems through the synergistic action of the pressing mechanism 4 and the adjusting mechanism 5.

[0036] In this embodiment, a pad 501 for connecting the body 1 is also installed on the bottom side of the first mounting plate 502 away from the pressing mechanism 4.

[0037] It should be noted that, on the one hand, the pad 501 can enhance the stability of the connection between the first mounting plate 502 and the seaming machine body 1. On the other hand, the pad 501 can be height adjusted according to the actual installation situation of the machine body 1, so that the first mounting plate 502 is in a suitable horizontal position, ensuring that the sliding parts 504 and other components on the adjustment mechanism 5 can work normally, and improving the installation accuracy and adaptability of the clamping device.

[0038] In this embodiment, the sliding member 504 passes through the second mounting plate 503 and the first mounting plate 502 simultaneously through the first sliding groove 5031 and the second sliding groove, and is perpendicular to the surface of the body 1.

[0039] The sliding member 504 includes a first cylinder 5041, a first block 5042, a second block 5043, and a second cylinder 5044 that are fixedly connected in sequence. The first spring 505 and the screw 506 both abut against the first block 5042. The first block 5042 and the second block 5043 are in sliding engagement with the first slide groove 5031 and the second slide groove in sequence. The second cylinder 5044 is rotatably connected to the roller 5045.

[0040] It should be noted that the specific structural design of the sliding component 504 has several advantages. The sliding component 504 is perpendicular to the surface of the machine body 1, ensuring that the force exerted by the roller 5045 on the sheet metal is accurate during adjustment, resulting in uniform force distribution on the sheet metal during clamping and preventing displacement or deformation. The design of the first cylinder 5041 and the second cylinder 5044 provides a stable support structure for the sliding component 504, while also facilitating connection and assembly with other components. The sliding engagement of the first block 5042 and the second block 5043 with the first slide groove 5031 and the second slide groove allows the sliding component 504 to slide smoothly along a preset trajectory under the action of the adjusting screw 506, achieving precise position adjustment. The first spring 505 and the screw 506 abut against the first block 5042. The first spring 505 can provide a certain buffer and reset function. When the adjusting screw 506 adjusts the sliding member 504, the first spring 505 can balance part of the force to prevent the sliding member 504 from being damaged due to excessive force. At the same time, it can also help the sliding member 504 return to its initial state after adjustment, thereby improving the stability and reliability of the device. The first cylinder 5041 also facilitates manual movement and adjustment of the sliding member 504.

[0041] In this embodiment, the pressure roller 402 is perpendicular to the surface of the machine body 1. The pressure roller 402 includes an elastic rod and a roller rotatably connected to the elastic rod.

[0042] It should be noted that the perpendicular design of the pressure roller 402 to the surface of the machine body 1 ensures that the pressure roller 402 can act perpendicularly on the surface of the sheet metal, thereby applying uniform pressure to the sheet metal and ensuring that the sheet metal is fixed in position during the seaming process, preventing slippage or displacement. The elastic rod provides the pressure roller 402 with a certain degree of elastic buffering capacity. When the sheet metal thickness is uneven or subjected to external impact, the elastic rod can elastically deform, absorbing some energy and preventing the pressure roller 402 from excessively compressing the sheet metal and damaging it. It also ensures that the pressure roller 402 maintains good contact with the sheet metal surface, providing stable pressure. The roller is rotatably connected to the elastic rod, allowing the roller to roll freely when in contact with the sheet metal, reducing friction between the roller and the sheet metal, lowering resistance during sheet metal movement, facilitating smooth sheet metal transport and seaming, and improving processing efficiency and quality.

[0043] In this embodiment, at least three sliders 504 are provided.

[0044] It should be noted that the inclusion of at least three sliding elements 504 is a deliberate choice. Three or more sliding elements 504 create multiple support points on the side of the sheet metal, more evenly distributing the weight of the sheet and the forces generated during the seaming process, thus enhancing the clamping stability. Compared to fewer sliding elements 504, multiple sliding elements 504 can better adapt to sheets of different shapes and sizes, especially for irregularly shaped or large sheets. Multiple sliding elements 504 can support and clamp the sheet from different positions, preventing deformation or wobbling during processing. Furthermore, the synergistic effect of multiple sliding elements 504 can increase the load-bearing capacity of the entire clamping device, enabling the seaming machine to handle thicker or heavier sheets and broadening its application range.

[0045] In summary, this seaming machine clamping device, by adjusting the position of the sliding member 504 through the adjusting screw 506, in conjunction with the elastic force of the second spring 507 and the bottom rollers 5045 of multiple sliding members 504, can flexibly adapt to different shaped plates, overcome the problem that the existing fixed shape of the stop block cannot act on curved plates, achieve effective adaptation and clamping of various types of plates, and improve the versatility of seaming processing.

[0046] The clamping device of this seaming machine, with the help of the pressure roller 402 in the pressing mechanism 4 which is perpendicular to the machine body 1 and contains an elastic rod and roller, and the coordinated operation of the various components of the adjusting mechanism 5, not only meets the requirements of the flat seaming mechanism 2, but can also be adapted to the arc seaming mechanism 3. This solves the problem that the existing stop is only suitable for the flat seaming mechanism 2 and cannot meet the requirements of the arc material stop, thus enhancing the multi-functionality of the seaming machine.

[0047] Working Principle: When the clamping device of this seaming machine is working, the sheet metal is first placed in the clamping device, so that one side of the sheet metal abuts against the inner side of the L-shaped plate 401. At the same time, rotating the adjusting screw 506 pushes or pulls the sliding member 504 to slide in the first and second slide grooves 5031 and 5032. The second spring 507 provides elastic force assistance, allowing the roller 5045 at the bottom of the sliding member 504 to support and position the side of the sheet metal from below, in order to adapt to different shaped sheets metal (such as ring-shaped sheets metal). In the pressing mechanism 4, the pressure roller 402, under the action of the elastic rod, makes the roller press vertically against the upper surface of the sheet metal. During processing, the sheet metal is manually moved forward, the pressure roller 402 rolls to reduce friction, and the sliding member 504 adaptively adjusts according to the shape of the sheet metal to ensure effective clamping. Facing different shaped sheets metal and seaming mechanisms such as flat edges and arcs, the two work together to meet diverse clamping needs and ensure smooth seaming processing.
