Description

Technical Field

[0001] The utility model relates to the technical field of sheet processing, and specifically relates to a clamping and positioning device for hollow board processing. Background Technique

[0002] With the rapid progress of global industrial technology, due to its remarkable characteristics such as light weight, environmental protection, and corrosion resistance, hollow boards have shown broad application prospects in multiple industrial fields. Whether it is ensuring the safe transportation of products in the packaging industry, serving as high-quality thermal insulation and sound insulation materials in the construction field, or being used as loading boards for transportation tools, hollow boards play an indispensable role. However, during the processing of hollow boards, especially during high-precision and high-efficiency processes such as cutting, punching, and engraving, the accuracy of clamping and positioning is particularly crucial.

[0003] When traditional hollow board processing equipment clamps hollow boards, it often relies on simple and traditional mechanical clamping methods, such as using pressing plates, jigs, and other tools to fix materials. However, these traditional clamping methods have exposed a series of problems in practical applications, especially when dealing with large or irregularly shaped hollow boards, these problems become particularly prominent and intractable. First of all, uneven clamping force is a common problem with these traditional methods. Since the designs of pressing plates and jigs are often based on standard sheet sizes and shapes, when facing hollow boards of different sizes or irregular shapes, they often cannot provide uniform clamping force, which can cause local deformation or displacement of the hollow board during processing, seriously affecting the processing accuracy and product quality. Secondly, inaccurate positioning is another important problem. Due to the limitations of the clamping method, traditional hollow board processing equipment often has difficulty achieving high-precision positioning of hollow boards, which not only increases the processing difficulty but also may lead to the accumulation of processing errors, ultimately affecting the overall quality of the product. Especially during precision cutting, punching, or engraving processes, the accuracy of positioning is even more crucial. In addition, cumbersome operation is also a significant drawback of traditional clamping methods. Since manual adjustment of the position and clamping force of the jig is required, operators need to spend a lot of time and effort to ensure that the hollow board is correctly clamped, which not only reduces the processing efficiency but also increases the labor intensity of the operators. At the same time, due to the uncertainty during the operation process, it also increases the safety risks during the processing process. Content of the Utility Model

Specific embodiments

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0041] Combined with Figures 1 - 5 As shown, a clamping and positioning device for processing hollow plates of the present invention includes a base 1 provided on a hollow plate processing machine.

[0042] The electric slide rail 2 is fixedly installed on one side surface of the base 1, and the number thereof is two and is symmetrically distributed according to the center of the base 1.

[0043] The conveying roller assembly 3 is arranged on the mobile end of the electric slide rail 2, and its number and distribution position are adapted to the electric slide rail 2. It can adjust the distance between the two conveying roller assemblies 3 under the drive of the electric slide rail 2 to adapt to hollow plates of different sizes.

[0044] The side limiting assembly 4 is arranged on the base 1, and it is used to press the side part of the hollow plate against the conveying roller assembly 3 to limit the side of the hollow plate.

[0045] The rotating end abutting assembly 5 is arranged on one side surface of the base 1 and between the two electric slide rails 2, and it can abut and limit one side end of the hollow plate.

[0046] The lifting limiting assembly 6 is arranged on one side surface of the base 1, and it can abut and limit the other side end of the hollow plate. Among them, with the mutual cooperation of the side limiting assembly 4, the rotating end abutting assembly 5 and the lifting limiting assembly 6, the hollow plate can be clamped and positioned above the conveying roller assembly 3.

[0047] The device includes a base 1 installed on a hollow plate processing machine. On one side surface of the base 1, two electric slide rails 2 are fixedly installed. These two electric slide rails 2 are symmetrically distributed based on the center of the base 1. On the moving end of the electric slide rail 2, a conveying roller assembly 3 is provided, and its quantity and distribution position are adapted to the electric slide rail 2. When it is necessary to clamp hollow plates of different sizes, the electric slide rail 2 will drive its moving end to move, thereby adjusting the distance between the two conveying roller assemblies 3 to adapt to hollow plates of different sizes. A side limiting component 4 is also provided on the base 1. This component is used to press the side of the hollow plate against the conveying roller assembly 3 to ensure that the hollow plate will not move horizontally during the processing, achieving the limit of the edge of the hollow plate. In addition, on one side surface of the base 1, at the position between the two electric slide rails 2, a rotating end pressing component 5 is provided. This component can rotate and press and limit one end of the hollow plate, further enhancing the stability of the hollow plate during the processing. At the same time, a lifting limiting component 6 is provided on the other side surface of the base 1. This component can be lifted as needed to press and limit the other end of the hollow plate. With the mutual cooperation of the side limiting component 4, the rotating end pressing component 5, and the lifting limiting component 6, the hollow plate can be stably clamped and positioned above the conveying roller assembly 3, ensuring that it will not move or deform during the processing. In summary, the clamping and positioning device for processing hollow plates of the present utility model drives the movement of the conveying roller assembly 3 through the electric slide rail 2, and with the use of the side limiting component 4, the rotating end pressing component 5, and the lifting limiting component 6, it realizes the efficient and stable clamping and positioning of the hollow plate, ensuring the processing accuracy and product quality.

[0048] In terms of electrical control, the device uses standard model electrical components available on the market and does not require special customization. In addition, the electrical control method and circuit connection of the device are based on the common knowledge of those skilled in the art and do not need to be elaborated too much.

[0049] The present utility model can be further configured in a preferred embodiment as: such as Figure 1 、 Figure 3As shown in the figure; a mounting seat 12 is fixedly installed on the moving end of the electric slide rail 2. On the opposite sides of two of the mounting seats 12, distance sensors 13 are fixedly installed. The two distance sensors 13 are arranged in a vertically staggered manner, that is, one is located above and the other is located below, but their detection directions are towards each other. When the electric slide rail 2 drives the moving end to move to adjust the distance between the two conveying roller assemblies 3, the two distance sensors 13 will continuously monitor the distance between them. Since they are arranged in a staggered manner, it can be ensured that no matter how the positions of the conveying roller assemblies 3 are adjusted, there is always one distance sensor 13 that can accurately measure the actual distance between them. The advantage of this design is that it provides a real-time feedback mechanism, enabling the clamping and positioning device to accurately know the current distance between the two conveying roller assemblies 3. By combining with the control system, the movement of the electric slide rail 2 can be automatically adjusted according to this real-time data, so as to ensure that the distance between the two conveying roller assemblies 3 precisely matches the size of the hollow board. This can not only improve the clamping accuracy and stability, but also reduce the errors and inconveniences caused by manual adjustment. In summary, by adding the mounting seat 12 and the distance sensor 13 on the moving end of the electric slide rail 2, we have further improved the intelligence and accuracy of the clamping and positioning device for hollow board processing, enabling it to better adapt to the processing requirements of hollow boards of different sizes.

[0050] In a preferred embodiment of the present utility model, it can be further configured as: As Figure 1 , Figure 3 shown; the conveying roller assembly 3 includes:

[0051] A moving seat 31, fixedly installed on the moving end of the electric slide rail 2, the number and distribution position of which are adapted to the electric slide rail 2, and the moving seat 31 can be displaced horizontally under the drive of the electric slide rail 2;

[0052] A plurality of transmission rollers 32 are provided and equally divided into two groups, which are respectively arranged on the two moving seats 31, and the outer sides thereof are in contact with the hollow board; and

[0053] The limiting convex ridges 33 are fixedly installed on the moving seat 31, and their quantity and distribution positions are adapted to the moving seat 31. The horizontal height of the limiting convex ridges 33 is higher than that of the transmission rollers 32. The conveying roller assembly 3 mainly consists of the moving seat 31, the transmission rollers 32 and the limiting convex ridges 33. First, the moving seat 31 is fixedly installed on the moving end of the electric slide rail 2, and its quantity and distribution positions are adapted to the electric slide rail 2. This means that as the moving end of the electric slide rail 2 moves horizontally, the moving seat 31 will also move horizontally accordingly. This design enables the conveying roller assembly 3 to flexibly adjust the distance between the two moving seats 31 according to the size of the hollow board under the drive of the electric slide rail 2. Secondly, as the core part of the conveying roller assembly 3, a plurality of transmission rollers 32 are provided and equally divided into two groups, which are respectively installed on the two moving seats 31. The outer sides of the transmission rollers 32 are in direct contact with the hollow board and are used to convey and support the hollow board during the processing. The design of the transmission rollers 32 enables the hollow board to move smoothly after processing and avoids surface damage caused by excessive friction. Finally, the limiting convex ridges 33 are fixedly installed on the moving seat 31, and their quantity and distribution positions are adapted to the moving seat 31. The horizontal height of the limiting convex ridges 33 is higher than that of the transmission rollers 32. The purpose of this design is to provide additional limiting and support for the hollow board through the limiting convex ridges 33 during the conveying process of the hollow board. When the hollow board is placed on the transmission rollers 32, the limiting convex ridges 33 can prevent the hollow board from shifting or shaking, thereby ensuring the stability and accuracy of the hollow board during the processing. In summary, the conveying roller assembly 3 realizes the efficient and stable clamping and conveying of the hollow board by the moving seat 31 moving horizontally under the drive of the electric slide rail 2 to adjust the distance between the two moving seats 31 to adapt to different sizes of hollow boards; conveying and supporting the hollow board through the transmission rollers 32; and providing additional limiting and support for the hollow board through the limiting convex ridges 33.

[0054] In a preferred embodiment of the present utility model, it can be further configured as: as Figure 1 , Figure 2 shown; the side limiting assembly 4 includes:

[0055] The bracket 41, one end of which is fixedly installed on one side surface of the base 1, and the other end is fixedly installed with a first electric push rod 42, and the output end of the first electric push rod 42 faces the side of the limiting convex ridge 33; and

[0056] The pushing and limiting member 43 is fixedly installed on the output end of the first electric push rod 42. It is displaced under the drive of the first electric push rod 42 to abut the side edge of the hollow plate against the limiting convex rib 33. The side edge limiting component 4 mainly includes a bracket 41, a first electric push rod 42, and a pushing and limiting member 43. First, the bracket 41 serves as the fixed base of the side edge limiting component 4. One end of it is fixedly installed on one side surface of the base 1. Such an installation position enables the side edge limiting component 4 to effectively limit one side of the hollow plate. Then, the other end of the bracket 41 is fixedly installed with a first electric push rod 42. The output end of the first electric push rod 42 faces the side of the limiting convex rib 33. Such a design enables the output end of the first electric push rod 42 to move towards the limiting convex rib 33 when it is driven. Finally, the pushing and limiting member 43 is fixedly installed on the output end of the first electric push rod 42. When the first electric push rod 42 is activated and driven, the pushing and limiting member 43 will be displaced accordingly. The direction of this displacement is towards the limiting convex rib 33, so that the pushing and limiting member 43 can tightly abut the side edge of the hollow plate against the limiting convex rib 33. Through this design, the side edge limiting component 4 can, under the drive of the first electric push rod 42, automatically adjust the position of the pushing and limiting member 43 according to the actual size and position of the hollow plate to ensure that the side edge of the hollow plate is stably abutted against the limiting convex rib 33. This not only improves the automation degree of the clamping and positioning device but also enhances its ability to adapt to hollow plates of different sizes, further improving the processing accuracy and efficiency.

[0057] In a preferred embodiment of the present utility model, it can be further configured as follows: As Figure 1 , Figure 4 shown; the rotating end abutting component 5 includes:

[0058] The first hinge seat 51 is fixedly installed on one side surface of the base 1 and is located between the two electric slide rails 2;

[0059] The hinge member 52 is hinged to the first hinge seat 51 and can rotate and displace with the first hinge seat 51 as the origin;

[0060] The second electric push rod 53 is fixedly installed on the hinge member 52 and can be displaced synchronously with the movement of the hinge member 52;

[0061] The second hinge seat 54 is fixedly installed on one side surface of the base 1 and is located between the two electric slide rails 2; and

[0062] The end contact plate 55 is hinged to the second hinge seat 54 and can rotate and displace with the second hinge seat 54 as the origin. The output end of the second electric push rod 53 is hinged to the end contact plate 55. Driven by the second electric push rod 53, the end contact plate 55 can be driven to rotate so that one side surface of the end contact plate 55 contacts one side end of the hollow plate, thereby clamping and positioning one side end of the hollow plate. The rotating end actuating assembly 5 mainly consists of a first hinge seat 51, a hinge member 52, a second electric push rod 53, a second hinge seat 54, and an end contact plate 55. First, the first hinge seat 51 is fixedly installed on one side surface of the base 1, between the two electric slide rails 2. This hinge seat provides a rotation reference point for the hinge member 52. Then, the hinge member 52 is hinged to the first hinge seat 51 and can rotate and displace according to the first hinge seat 51 as the origin as needed. This design enables the hinge member 52 to flexibly adjust its position and angle. The second electric push rod 53 is fixedly installed on the hinge member 52 and will displace synchronously with the movement of the hinge member 52. This electric push rod is the driving element of the rotating end actuating assembly 5 and is used to provide the necessary power. The second hinge seat 54 is also fixedly installed on one side surface of the base 1, between the two electric slide rails 2. This hinge seat provides a rotation reference point for the end contact plate 55. Finally, the end contact plate 55 is hinged to the second hinge seat 54 and can rotate and displace with the second hinge seat 54 as the origin. The output end of the second electric push rod 53 is hinged to the end contact plate 55. In this way, when the second electric push rod 53 is activated and driven, it can drive the end contact plate 55 to rotate. Driven by the second electric push rod 53, the end contact plate 55 will rotate to a suitable angle and position so that one of its side surfaces contacts one side end of the hollow plate. In this way, the rotating end actuating assembly 5 can accurately clamp and position one side end of the hollow plate, ensuring the stability and accuracy of the hollow plate during the processing.

[0063] In a preferred embodiment of the present utility model, it can be further configured as: as Figure 1 , Figure 5 shown; the lifting limit assembly 6 includes:

[0064] A fixed seat 61, fixedly installed at the end of the base 1;

[0065] A first support rod 62, one end of which is hinged to the fixed seat 61 and can rotate and displace with the fixed seat 61 as the origin;

[0066] A third electric push rod 63, fixedly installed on the fixed seat 61, and its output end faces away from the first support rod 62;

[0067] The movable member 64 is disposed at the output end of the third electric push rod 63 and can be displaced laterally under the drive of the third electric push rod 63;

[0068] The second support rod 65, one end of which is hinged to the movable member 64 and can rotate and displace with the movable member 64 as the origin; and

[0069] The lifting limit plate 66 is disposed at the other end portions of the first support rod 62 and the second support rod 65 and can drive the lifting limit plate 66 to perform vertical displacement under the transmission of the first support rod 62 and the second support rod 65, so as to abut and position the other side end of the hollow plate. The lifting limit assembly 6 mainly includes a fixed seat 61, a first support rod 62, a third electric push rod 63, a movable member 64, a second support rod 65 and a lifting limit plate 66. First, the fixed seat 61 is fixedly installed at the end of the base 1 as the basic support of the entire lifting limit assembly 6. Then, one end of the first support rod 62 is hinged to the fixed seat 61 and it can rotate and displace around the fixed seat 61 as required. This design enables the first support rod 62 to adjust the angle within a certain range. The third electric push rod 63 is fixedly installed on the fixed seat 61 and its output end faces away from the first support rod 62. The third electric push rod 63 serves as the power source of the lifting limit assembly 6 and is responsible for providing the necessary thrust. The movable member 64 is disposed at the output end of the third electric push rod 63. When the third electric push rod 63 is activated and driven, the movable member 64 will be displaced laterally under the drive of its output end. One end of the second support rod 65 is hinged to the movable member 64 and it can perform corresponding rotational displacement according to the movement of the movable member 64. This design enables the second support rod 65 to adjust the angle around its hinge point with the movable member 64 under the drive of the movable member 64. The lifting limit plate 66 is disposed at the other end portions of the first support rod 62 and the second support rod 65. As the first support rod 62 and the second support rod 65 rotate and displace, the lifting limit plate 66 will be driven to perform vertical displacement. Specifically, when the third electric push rod 63 pushes the movable member 64 to move, the second support rod 65 will rotate around its hinge point with the movable member 64, and at the same time the first support rod 62 will also rotate around its hinge point with the fixed seat 61. The rotational movements of these two will act together on the lifting limit plate 66 to make it perform vertical lifting movement. Finally, the lifting limit plate 66 can be lifted to a suitable position to abut and position the other side end of the hollow plate. This design ensures the stability and accuracy of the hollow plate during the processing process and improves the processing efficiency.

[0070] In a preferred embodiment of the present utility model, it can be further configured as: such as Figure 1 、 Figure 5As shown; a first sliding hole 7 is processed on the surface of the lifting limit plate 66, a first notch is processed on one end of the first support rod 62 and the second support rod 65 close to the lifting limit plate 66, a first pulley 8 is arranged in the first notch, and the first pulley 8 is slidably connected to the inner side of the first sliding hole 7, a second sliding hole 9 is processed on the surface of the fixed seat 61, a second notch is processed on one end of the movable member 64 close to the fixed seat 61, a second pulley 10 is arranged in the second notch, and the second pulley 10 is slidably connected to the inner side of the second sliding hole 9, the lifting limit plate 66 is used as the main lifting and positioning component, and a first sliding hole 7 is processed on its surface, the first sliding hole 7 not only provides a path for the lifting and lowering movement of the lifting limit plate 66, but also cooperates with the first pulley 8 on the first support rod 62 and the second support rod 65 to ensure the stability of the lifting process, the first support rod 62 and the second support rod 65 are processed on one end close to the lifting limit plate 66, a first notch is processed, and a first pulley 8 is arranged in the first notch, and the design of the first pulley 8 allows the first support rod 62 and the second support rod 65 to rotate in displacement The lifting and limiting assembly 66 can realize efficient and stable lifting and limiting movement through the cooperation of the first support rod 62, the second support rod 65, the first pulley 8, the second pulley 10, the first slide hole 7 and the second slide hole 9.

[0071] In a preferred embodiment, the present invention can be further configured as follows: Figure 1 , Figure 5As shown in the figure; a pin shaft 11 is provided at the center of the second support rod 65. One end of the pin shaft 11 penetrates and extends to the other side surface of the first support rod 62. The first support rod 62 and the second support rod 65 are arranged in a cross - distributed manner. In the lifting and limiting component 6, the design of the second support rod 65 and the first support rod 62 is for collaborative work. Through their movements, the lifting and limiting plate 66 is driven to perform vertical displacement. To achieve this function, a pin shaft 11 is provided at the center of the second support rod 65. One end of the pin shaft 11 penetrates and extends to the other side surface of the first support rod 62. Specifically, the first support rod 62 and the second support rod 65 are arranged in a cross - distributed manner. This cross - distributed design enables the two support rods to rotate within a certain angle range with the pin shaft 11 as the intersection point. When the third electric push rod 63 drives the moving part 64 to move, since one end of the second support rod 65 is hinged to the moving part 64, the second support rod 65 will rotate around its hinge point with the moving part 64. At the same time, due to the existence of the pin shaft 11, the first support rod 62 will also rotate around the pin shaft 11 accordingly. Through this cross - distributed design, the rotational movements of the first support rod 62 and the second support rod 65 restrict and cooperate with each other, and jointly act on the lifting and limiting plate 66, enabling it to perform lifting movement in the vertical direction. Specifically, when the second support rod 65 rotates upward, the first support rod 62 rotates downward, and vice versa. This movement mode ensures that the lifting and limiting plate 66 can be lifted and lowered smoothly and accurately to the required position, thereby realizing the abutting and positioning of the hollow board. In short, through the cross - distributed design of the first support rod 62 and the second support rod 65 connected by the pin shaft 11, the lifting and limiting component 6 can achieve efficient and stable lifting movement, providing reliable positioning support for the processing of the hollow board.

[0072] The specific working principle of a clamping and positioning device for processing hollow boards of the present utility model is as follows:

[0073] The clamping and positioning device for processing hollow boards aims to ensure that hollow boards of different sizes can be accurately and stably placed above the conveying roller assembly on the processing machine during the processing process. The entire device realizes the precise positioning and clamping of the hollow board through the collaborative work of the electric slide rail, the side limiting component, the rotating end abutting component, and the lifting and limiting component.

[0074] First, the electric slide rail 2 drives the conveying roller assembly 3 to perform a lateral displacement through the mounting seat 12 on its mobile end. The conveying roller assembly 3 includes a moving seat 31, a transmission roller 32, and a limiting rib 33. They cooperate together to adapt to hollow plates of different sizes, ensure that the hollow plate is stably placed on the transmission roller 32, and perform side limiting through the limiting rib 33. Then, the side limiting assembly 4 starts to work. The first electric push rod 42 supported by the bracket 41 drives the limiting member 43 to move, tightly abutting the side of the hollow plate against the limiting rib 33, achieving precise positioning and fixing of the side of the hollow plate. Then, the rotating end abutting assembly 5 abuts and limits one end of the hollow plate. The second electric push rod 53 drives the hinge member 52 and the end abutting plate 55 to perform rotational displacement around their respective first hinge seats 51 and second hinge seats 54. When the second electric push rod 53 extends, the end abutting plate 55 will rotate to a suitable position, bringing its one side surface into close contact with one end of the hollow plate to complete the clamping and positioning. Finally, the lifting limiting assembly 6 abuts and limits the other end of the hollow plate. The third electric push rod 63 serves as the power source, driving the movable member 64 to perform a lateral displacement. The movable member 64 slides through the second pulley 10 in the second sliding hole 9 to ensure smooth movement. At the same time, the second support rod 65 hinged to the movable member 64 rotates around its hinge point with the movable member 64, and drives the first support rod 62 to rotate around its hinge point with the fixed seat 61 through the pin shaft 11. The rotational movements of these two support rods will act together on the lifting limiting plate 66, driving the lifting limiting plate 66 to perform a vertical displacement through the sliding of the first pulley 8 in the first sliding hole 7. When the lifting limiting plate 66 moves to a suitable position, it will be in close contact with the other end of the hollow plate to complete the abutting and limiting.

[0075] In summary, through the precise cooperation of the electric slide rail, the side limiting assembly, the rotating end abutting assembly, and the lifting limiting assembly, the clamping and positioning device for processing hollow plates can achieve precise clamping and positioning of hollow plates of different sizes, providing a stable and reliable foundation for the subsequent processing process.
