Description

Technical Field

[0001] This utility model belongs to the field of mechanical processing technology, specifically a positioning device for grooved wire cutting. Background Technology

[0002] With the continuous development of cutting technology, positioning devices are increasingly widely used in the field of groove cutting, and their performance directly affects the accuracy and efficiency of cutting. However, existing positioning devices still have many shortcomings in practical applications. On the one hand, traditional positioning devices usually rely on complex mechanical structures for fixing and adjustment, which is cumbersome and inefficient, making it difficult to meet the needs of modern high-efficiency production. On the other hand, although some devices have achieved a certain degree of automated positioning, their adaptability and flexibility are insufficient when dealing with workpieces of different sizes or shapes, leading to a decrease in positioning accuracy and thus affecting the cutting quality.

[0003] A search revealed a laser cutting positioning tool with publication number CN118905464B. This tool uses a pair of symmetrical positioning mechanisms to stably clamp a circuit board and utilizes a suction function to handle the carbon powder generated during cutting, thus improving the cutting effect. However, this design is mainly for cutting specific materials such as circuit boards and lacks adaptability to complex-shaped workpieces in groove cutting. Furthermore, the limited adjustment range of its positioning mechanism makes it difficult to meet the needs of rapid switching between multiple workpiece specifications, limiting its application in diverse production environments. In addition, a laser cutting machine and positioning method with publication number CN116851933B, which uses an extruder and dynamically adjusted positioning mechanism to ensure that irregularly shaped workpieces do not move due to changes in the center of gravity during cutting, performs well in handling irregularly shaped workpieces. Although this device performs well in handling irregularly shaped workpieces, its positioning system relies on a complex mechanical linkage structure, which not only increases the manufacturing cost and maintenance difficulty of the equipment but also may lead to positioning instability when processing smooth or fragile materials due to the friction between the extruder and the workpiece contact surface.

[0004] For positioning requirements of thin plates or irregularly shaped workpieces, existing technologies propose a combination of vacuum chucks and adjustable grippers to adapt to different shapes and prevent workpiece deformation. However, this combination still faces problems such as insufficient adaptability and operational complexity in practical applications, especially when handling complex groove cutting tasks, where it is difficult to balance positioning accuracy and operational efficiency. Therefore, developing a positioning device for groove cutting that can flexibly adapt to workpieces of different shapes and sizes, is easy to operate, and has high positioning accuracy has become an urgent technical challenge to be solved.

[0006] To achieve the above objectives, the specific technical solution of the positioning device for grooved wire cutting of this utility model is as follows:

[0007] A positioning device for grooved wire cutting includes a base and a positioning assembly. The positioning assembly is mounted on the base and includes a fixed plate and a movable plate. The fixed plate is fixedly connected to the base, and the movable plate is slidably connected to the base via a slide rail.

[0010] Furthermore, the movable plate includes a first movable plate and a second movable plate, which are slidably connected to the base via slide rails. Both the first and second movable plates are equipped with adjusting threaded rods to enable rapid adjustment of the movable plate position.

[0011] Furthermore, both the first and second movable plates are provided with multiple elastic clamping mechanisms, which are evenly distributed along the length of the movable plates, and the end of the elastic clamping mechanism away from the movable plate is connected to the fixed plate.

[0012] Furthermore, the elastic clamping mechanism includes a spring and a jaw. The two ends of the spring are connected to a fixed plate and a movable plate, respectively. The jaw is located in the middle of the spring, and a flexible pad is provided on the inner side of the jaw to prevent damage to the workpiece surface.

[0013] Furthermore, the vacuum adsorption pore includes a first adsorption pore and a second adsorption pore. The first adsorption pore is disposed on the fixed plate, and the second adsorption pore is disposed on the movable plate. The first adsorption pore and the second adsorption pore are connected to an external vacuum pump through an air pipe.

[0014] Furthermore, multiple elastic clamping mechanisms are vertically mounted on the fixed plate and the movable plate, and the ends of the multiple elastic clamping mechanisms away from the fixed plate and the movable plate are connected to the grippers to ensure that the clamping force is evenly distributed.

[0015] Furthermore, the slide rail is T-shaped to ensure a tight fit between the slide rail and the base, enhancing the stability of the movable plate during sliding.

[0016] Furthermore, both the fixed plate and the movable plate are L-shaped, so that the L-shaped openings of the fixed plate and the movable plate can be welded to the base, thereby enhancing the rigidity of the overall structure.

[0017] The positioning device for grooved wire cutting of this utility model has the following advantages:

[0018] By incorporating a fixed plate and a movable plate on the base, combined with an elastic clamping mechanism and a vacuum suction hole, rapid positioning and stable clamping of workpieces of different sizes and shapes are achieved, significantly improving positioning efficiency and accuracy.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The utility model will be further described in detail below with reference to the accompanying drawings.

[0029] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] The utility model provides a positioning device for grooved wire cutting, the structure of which is as follows: Figures 1 to 4As shown, the device includes a base 1, a fixed plate 2, a movable plate 3, a slide rail 4, elastic clamping mechanisms 5, and a vacuum adsorption hole 6. The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. The base 1 is the basic component of the entire device, with a flat upper surface and sufficient rigidity to support other components. The fixed plate 2 includes a first fixed plate 7 and a second fixed plate 8, both of which are fixedly connected to the base 1 by bolts 9, ensuring the stability of the fixed plate 2 during operation. Both the first fixed plate 7 and the second fixed plate 8 are L-shaped, with their L-shaped openings welded to the base 1, further enhancing the rigidity of the overall structure. The fixed plate 2 is provided with multiple elastic clamping mechanisms 5, which are evenly distributed along the length of the fixed plate 2 to ensure that the clamping force is evenly applied to the workpiece surface.

[0031] The movable plate 3 includes a first movable plate 10 and a second movable plate 11, both of which are slidably connected to the base 1 via slide rails 4. The slide rails 4 have a T-shaped design, which allows them to fit tightly against the base 1, thereby enhancing the stability of the movable plate 3 during sliding. Both the first movable plate 10 and the second movable plate 11 are rotatably equipped with adjusting threaded rods 12. These adjusting threaded rods 12 are rotatably connected to the movable plate 3, passing through and threadedly fitted onto the support block of the base 1. The operator can quickly adjust the position of the movable plate 3 by rotating the adjusting threaded rods 12 to accommodate workpieces of different sizes. The movable plate 3 also has multiple elastic clamping mechanisms 5, which are evenly distributed along the length of the movable plate 3 and correspond to the elastic clamping mechanisms 5 on the fixed plate 2, working together to clamp the workpiece.

[0032] The elastic clamping mechanism 5 is one of the core components of this utility model, and its structure is as follows: Figure 4 As shown, the device includes a spring 13 and a gripper 14. The two ends of the spring 13 are connected to the fixed plate 2 and the movable plate 3, respectively, and the gripper 14 is located in the middle of the spring 13. A flexible pad 15 is provided on the inner side of the gripper 14. The flexible pad 15 is made of a wear-resistant and elastic material, which can effectively protect the workpiece surface during clamping and prevent damage to the workpiece surface due to excessive clamping. When the workpiece is placed between the fixed plate 2 and the movable plate 3, the spring 13 automatically adjusts its extension and retraction according to the size of the workpiece, thereby achieving flexible clamping of the workpiece. This design not only avoids workpiece deformation due to excessive clamping force but also ensures uniform distribution of clamping force and improves positioning accuracy.

[0033] The vacuum adsorption hole 6 is another important component of this invention, comprising a first adsorption hole 16 and a second adsorption hole 17. The first adsorption hole 16 is disposed on the fixed plate 2, and the second adsorption hole 17 is disposed on the movable plate 3. The first adsorption hole 16 and the second adsorption hole 17 are connected to an external vacuum pump via air pipes. After the external vacuum pump is activated, a negative pressure is generated within the adsorption holes, thereby firmly adsorbing the workpiece onto the fixed plate 2 and the movable plate 3. This adsorption method is particularly suitable for positioning thin plates or irregularly shaped workpieces, because traditional mechanical clamping methods may not be able to effectively fix such workpieces, while vacuum adsorption can provide uniform adsorption force, ensuring that the workpiece remains stable throughout the entire processing.

[0034] In practical applications, the positioning device of this invention can be widely used in the field of grooved wire cutting. For example, when processing a thin metal sheet, the operator first places the metal sheet between the fixed plate 2 and the movable plate 3. Then, by rotating the adjusting threaded rod 12, the positions of the first movable plate 10 and the second movable plate 11 are adjusted, so that the movable plate 3 is close to the workpiece and initially clamps the workpiece. At this time, the spring 13 in the elastic clamping mechanism 5 will automatically adjust its extension and contraction according to the thickness of the workpiece, and the jaws 14 clamp the workpiece under the action of the spring 13, while the flexible gasket 15 protects the surface of the workpiece from damage. Next, the external vacuum pump is started, and the first suction hole 16 and the second suction hole 17 start working. The air in the suction hole is extracted through the air pipe to form a negative pressure environment, thereby firmly adsorbing the workpiece on the fixed plate 2 and the movable plate 3. This double fixing method not only ensures the stability of the workpiece, but also avoids the problem of workpiece deformation caused by excessive clamping force.

[0035] To further illustrate the working principle of this utility model, a detailed description is provided below in conjunction with a specific application scenario. Suppose that an irregularly shaped plastic workpiece needs to be grooved. Because plastic is soft and easily deformed, traditional mechanical clamping methods may result in indentations or even damage to the workpiece surface. In this situation, the positioning device of this utility model can fully leverage its advantages. The operator first places the plastic workpiece between the fixed plate 2 and the movable plate 3, and then adjusts the position of the movable plate 3 by adjusting the threaded rod 12, so that the elastic clamping mechanism 5 initially clamps the workpiece. Since the spring 13 in the elastic clamping mechanism 5 has a certain elastic range, it can automatically adjust the clamping force according to the shape of the workpiece, avoiding deformation due to excessive clamping. At the same time, the flexible gasket 15 effectively protects the workpiece surface, preventing indentations. Subsequently, the external vacuum pump is activated, and the first suction hole 16 and the second suction hole 17 begin to work. Air is extracted from the suction holes through the air pipe, creating a negative pressure environment, thereby firmly adsorbing the workpiece onto the fixed plate 2 and the movable plate 3. This adsorption method not only provides uniform adsorption force, but also compensates for the shortcomings of the elastic clamping mechanism 5 on certain complex-shaped workpieces, ensuring that the workpiece remains stable throughout the entire processing.

[0036] Furthermore, the positioning device of this invention possesses strong adaptability and flexibility, enabling it to meet the rapid switching requirements of workpieces of various sizes. For example, when processing a batch of metal workpieces of different sizes, the operator only needs to adjust the position of the movable plate 3 by adjusting the threaded rod 12 to accommodate workpieces of different sizes. Since the elastic clamping mechanism 5 can automatically adjust the clamping force according to the workpiece size, there is no need to frequently change fixtures or adjust clamping parameters, greatly improving work efficiency. Simultaneously, the design of the vacuum adsorption hole 6 allows the device to easily handle the positioning needs of thin plates or irregularly shaped workpieces, further expanding the device's application range.

[0037] In summary, the positioning device for groove cutting of this utility model achieves rapid positioning and stable clamping of workpieces of different sizes and shapes by setting a fixed plate 2 and a movable plate 3 on the base 1, combined with an elastic clamping mechanism 5 and a vacuum adsorption hole 6. The elastic clamping mechanism 5 can automatically adjust the clamping force according to the workpiece size, avoiding workpiece deformation due to excessive clamping, while the flexible gasket 15 effectively protects the workpiece surface. The vacuum adsorption hole 6 provides adsorption force through an external vacuum pump, further enhancing the stability of the workpiece, especially suitable for positioning thin plates or irregularly shaped workpieces. In addition, the movable plate 3 is slidably connected to the base 1 through a slide rail 4 and is equipped with an adjusting threaded rod 12, which facilitates quick position adjustment, meets the switching needs of multiple workpiece specifications, and improves the adaptability and flexibility of the device. The positioning device of this utility model has a simple structure and is easy to operate, which can significantly improve the efficiency and accuracy of groove cutting, and has high practical value and promotion prospects.
