Description

Technical Field

[0001] This utility model relates to a pressing device, and more particularly to a pressing device suitable for linear track laser processing equipment. Background Technology

[0002] Current laser processing equipment primarily uses linear tracks for feeding and docking. However, this method has the following drawbacks during use:

[0003] 1. Insufficient adaptability: The fixed spacing of the mounting frames in traditional pressing devices makes it difficult to adapt to the processing requirements of materials with different widths. For example, the existing technology CN202420814333.7 discloses a transport mechanism and processing equipment. Its synchronous wheel transmission structure is mainly used for material conveying and does not involve a flexible adjustment mechanism for the mounting frame spacing.

[0004] 2. Unstable feeding accuracy: Some equipment uses ordinary belt drive for feeding, which is prone to slippage leading to material positioning deviation. For example, a laser engraving and cutting machine disclosed in Chinese patent CN119387866A reduces the elongation at high speeds through synchronous belt drive, but it does not use a toothed structure, so there is still a risk of slippage.

[0005] 3. Uneven pressure distribution: Existing cylinder-driven clamping devices often suffer from uneven pressure distribution due to single-cylinder drive or lack of guiding structure. For example, Chinese patent CN202322232720 discloses a flexible clamping device. Although it uses cylinder drive, it requires complex adjusting shims or power adjustment to achieve pressure balance, which is cumbersome to operate and has limited accuracy.

[0006] 4. Limited versatility: Traditional equipment has a high degree of integration between the pressure module and the track structure. If it is necessary to switch to a regular track, the main body of the equipment often needs to be modified. For example, Chinese patent CN222843349U discloses a modular ground-rail laser cutting machine bed. Although it adopts a modular design, it mainly focuses on the bed structure and does not address the compatibility switching between the pressure module and a regular track.

[0007] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a pressure device suitable for linear track laser processing equipment, making it more industrially valuable. Utility Model Content

[0008] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a pressing device suitable for linear track laser processing equipment.

[0009] This utility model discloses a pressing device applicable to linear track laser processing equipment, comprising a mounting plate, wherein: a fixed mounting frame is mounted on the mounting plate, and a displacement adjustment assembly is also provided on the mounting plate; an adjustment mounting frame is mounted on the displacement adjustment assembly; a material guiding mechanism is mounted on the top of both the fixed mounting frame and the adjustment mounting frame via a cylinder; a feeding assembly is mounted on the lower end of the fixed mounting frame and the adjustment mounting frame corresponding to the material guiding mechanism; the piston rod of the cylinder is connected to a connecting piece of the material guiding mechanism; the material guiding mechanism is a pressure plate; the feeding assembly includes several pulleys, a belt assembly is mounted on each pulley, and a drive motor is connected to each pulley; miniature sliders are mounted on the inner sides of both the fixed mounting frame and the adjustment mounting frame, and the miniature sliders are connected to the corresponding pressure plate connecting pieces via connecting pieces.

[0010] Furthermore, in the aforementioned pressing device applicable to linear track laser processing equipment, the micro slider is a linear ball slider, and the sliding track of the micro slider is perpendicular to the conveying direction of the fixed mounting frame and the adjusting mounting frame.

[0011] Furthermore, in the aforementioned pressing device applicable to linear track laser processing equipment, there are four cylinders, which are symmetrically fixed in pairs to the outside of the corresponding fixed mounting bracket and adjusting mounting bracket. The piston rods of the four cylinders extend and retract synchronously, so that the downward pressure of the pressure plate is evenly distributed on the upper surface of the reference processing material.

[0012] Furthermore, in the aforementioned pressing device applicable to linear track laser processing equipment, the pressure plate is a rigid metal plate, and the lower surface of the rigid metal plate is parallel to the upper surface of the reference processing material.

[0013] Furthermore, in the aforementioned pressing device applicable to linear track laser processing equipment, the connecting part is an L-shaped rigid casting, one end of which is bolted to the micro slider and the other end of which is bolted to the pressure plate.

[0014] Furthermore, in the aforementioned pressing device suitable for linear track laser processing equipment, the pulley is a toothed synchronous pulley.

[0015] Furthermore, in the aforementioned pressing device applicable to linear track laser processing equipment, when the pressure plate is pressed down, the surface parallelism error between the plate and the fixed mounting bracket and the adjustable mounting bracket is less than or equal to 0.05 mm.

[0016] Furthermore, in the aforementioned pressing device suitable for linear track laser processing equipment, the lower end of the mounting plate is provided with several docking guide rails.

[0017] Furthermore, in the aforementioned pressing device applicable to linear track laser processing equipment, the displacement adjustment component is a lead screw motor with a guide rail, a slider is mounted on the lead screw, and the slider is connected to the adjustment mounting frame.

[0018] By means of the above solution, this utility model has at least the following advantages:

[0019] 1. High adaptability and flexible adjustment to meet the processing needs of materials of different specifications: Through the cooperation of linear guide rail and lead screw in displacement adjustment component, the adjustment mounting frame is driven to move along linear guide rail, realizing flexible adjustment of the distance between it and fixed mounting frame, thereby adapting to reference processing materials of different widths and expanding the application range of the device.

[0020] 2. Stable and high-precision feeding ensures the reliability of the processing: The feeding assembly adopts multiple toothed synchronous pulleys, which transport materials through synchronous belt drive. The toothed structure can effectively prevent belt slippage and ensure the stability of material transportation. At the same time, the synchronous pulleys are directly driven by the drive motor through the coupling. The motor speed can be adjusted according to the processing requirements, which helps to ensure the accuracy of material transportation and provides a reliable material positioning basis for subsequent processing.

[0021] 3. Precise and uniform downward positioning, effectively improving processing accuracy: The pressure plate moves under the drive of the cylinder, and the pressure plate connector moves vertically through a micro slider, preventing the pressure plate from tilting when moving up and down, and ensuring the stability of the pressure plate movement; the four cylinders are symmetrically distributed in pairs, and the piston rods extend and retract synchronously, so that the downward pressure of the pressure plate is evenly distributed on the upper surface of the reference processing material, avoiding improper deformation of the material due to abnormal stress distribution, and the surface parallelism error between the pressure plate and the fixed mounting bracket and the adjusting mounting bracket is less than or equal to 0.05mm, which significantly improves the processing accuracy.

[0022] 4. High versatility and easy compatibility with ordinary track structures: The device adopts a modular replacement design. When an ordinary track without the downward pressing function is needed, simply remove the connecting bolts between the connector and the pressure plate, remove the pressure plate as a whole, and the ordinary track component can be directly installed. This design does not require modification of the main body of the equipment; the functional conversion can be completed through simple mechanical structure replacement, greatly improving the versatility and flexibility of the device.

[0023] The above description is only an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0032] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0033] like Figure 1 A pressing device suitable for linear track laser processing equipment includes a mounting plate 1, which serves as a basic support component. The mounting plate 1 is horizontally positioned and slides against the track beam of the linear track laser processing equipment via guide rails 11 distributed at its lower end, enabling rapid installation and fixation of the device to the equipment. Its unique feature is that a fixed mounting bracket 2 is vertically fixed to one side of the mounting plate 1, while a displacement adjustment assembly 3 is mounted on the other side. During implementation, the displacement adjustment assembly 3 includes a linear guide rail and a lead screw. The linear guide rail is fixed to the surface of the mounting plate 1, and the lead screw is connected to both ends of the mounting plate 1 and parallel to the linear guide rail. Simultaneously, a slider is threaded onto the lead screw, and the slider slides against the linear guide rail. The adjusting mounting bracket 4 is bolted to the slider, allowing it to move along the linear guide rail direction with the slider, thereby adjusting the distance between it and the fixed mounting bracket 2 to accommodate reference processing materials 12 of different widths.

[0034] During use, both the fixed mounting bracket 2 and the adjustable mounting bracket 4 have material guiding mechanisms mounted on their tops via cylinders 10. This facilitates guiding the reference processing material 12 into the corresponding position during use. At the lower end of the material guiding mechanism, corresponding to the fixed mounting bracket 2 and the adjustable mounting bracket 4, feeding components are installed, which can connect to an external feeding track to receive the reference processing material 12. Simultaneously, the piston rod of the cylinder 10 is connected to the material guiding mechanism connector 9. The material guiding mechanism is a pressure plate 5, which can adapt to the downward pressure and limiting processing needs of conventional processing materials. Furthermore, considering the need for stable and continuous feeding, the feeding component includes several pulleys 6, on which belt assemblies (not shown in the figure to avoid obstruction) are mounted, and drive motors 7 are also connected. Moreover, miniature sliders 8 are installed on the inner sides of both the fixed mounting bracket 2 and the adjustable mounting bracket 4. The miniature sliders 8 are connected to the corresponding pressure plates 5 via connectors 9. The presence of the miniature sliders 8 guides the pressure plate 5 connector 9 to move vertically, preventing the pressure plate 5 from tilting during vertical movement and increasing the rigidity of the structure.

[0035] In a preferred embodiment of this invention, the miniature slider 8 is a linear ball bearing slider, and its sliding track is perpendicular to the conveying direction of the fixed mounting frame 2 and the adjusting mounting frame 4. Simultaneously, four cylinders 10 are symmetrically fixed in pairs to the outer sides of their respective fixed mounting frames 2 and adjusting mounting frames 4. The piston rods of the four cylinders 10 extend and retract synchronously, ensuring that the downward pressure of the pressure plate 5 is evenly distributed on the upper surface of the reference processing material 12. This approach, while limiting the downward pressure, prevents abnormal stress distribution on the upper surface of the reference processing material 12, thus avoiding undue deformation.

[0036] Meanwhile, the material guiding mechanism uses a rigid metal plate pressure plate 5, the lower surface of which is precision machined to maintain parallelism with the upper surface of the reference processing material 12. When the pressure plate 5 is pressed down, the guiding action of the micro slider 8 and the synchronous drive of the cylinder 10 ensure that the parallelism between the pressure plate 5 and the surfaces of the fixed mounting bracket 2 and the adjusting mounting bracket 4 meets the processing accuracy requirements (in actual processing, high-precision parallelism can be achieved through machining and assembly adjustments). The highest point of the pressure plate 5 when it is raised is lower than the upper components of the laser processing equipment (such as the laser head bracket), effectively avoiding interference problems during equipment operation.

[0037] Furthermore, the connecting piece 9 is an L-shaped rigid casting, with one end bolted to the micro slider 8 and the other end bolted to the pressure plate 5. This forms a stable force transmission structure. The micro slider 8 is a linear ball slider, with its sliding track perpendicular to the material conveying direction. This not only restricts the degree of freedom of movement of the connecting piece 9 of the pressure plate 5, but also reduces frictional resistance through ball rolling, ensuring the smooth up-and-down movement of the pressure plate 5.

[0038] In practical implementation, the feeding assembly includes multiple toothed synchronous pulleys, achieving stable material conveying through synchronous belt drive. Its toothed structure prevents belt slippage, ensuring material conveying accuracy. The synchronous pulleys 6 are directly driven by the drive motor 7 via a coupling, and the motor speed can be adjusted according to processing requirements. When the laser processing equipment starts, the drive motor 7 drives the pulleys 6 to rotate, causing the reference processing material 12 to enter the equipment at a uniform speed along the track base. Simultaneously, the piston rod of the cylinder 10 retracts, driving the pressure plate 5 downwards via the connecting piece 9, pressing the material firmly and fixing it to the top of the fixed mounting frame 2 and the adjusting mounting frame 4, forming a stable processing state. Furthermore, when the pressure plate 5 is pressed down, the surface parallelism error between it and the fixed mounting frame 2 and the adjusting mounting frame 4 is less than or equal to 0.05mm, improving processing accuracy. Moreover, considering the need for a balance between the drive and energy-saving ratio of the pulleys 6, one pulley 6 can be connected to the drive motor 7 to form the driving pulley, while the other pulleys 6 form the driven pulleys.

[0039] Furthermore, to achieve compatibility with conventional track structures, this device features a modular replacement solution. When a conventional track without the downward pressure function is needed, simply remove the connecting bolts between the corresponding connector 9 and the pressure plate 5, remove the pressure plate 5 entirely, and the conventional track component can be directly installed. This design, through simple mechanical replacement, eliminates the need for modifications to the main equipment, greatly improving the device's versatility.

[0040] The working principle of this utility model is as follows:

[0041] When the online track laser processing equipment is running, the reference processing material 12 is conveyed from the upstream of the equipment to the processing position of the pressing device via a belt assembly. At this time, the lead screw of the displacement adjustment component 3 rotates, driving the slider and the adjusting mounting bracket 4 to move along the linear guide rail towards the fixed mounting bracket 2, until the distance between the adjusting mounting bracket 4 and the fixed mounting bracket 2 is adapted to the width of the reference processing material 12, ensuring that the pressure plate 5 can cover the upper surface of the reference processing material 12.

[0042] Once the reference material 12 reaches the designated processing position, the drive motor 7 stops rotating, and the belt assembly stops conveying. Subsequently, the piston rod of the cylinder 10 retracts, pulling down the pressure plate 5, causing the pressure plate 5 to descend vertically along the guide direction of the micro slider 8 until the lower surface of the pressure plate 5 presses against the upper surface of the reference material 12. The lower surface of the reference material 12 and the upper surfaces of the pressure plate 5, the fixed mounting bracket 2, and the adjusting mounting bracket 4 are in contact. The cooperation between the pressure plate 5 and the track base surface presses and fixes the reference material 12, preventing it from moving during the cutting process.

[0043] After cutting is completed, the piston rod of cylinder 10 returns to its original position, causing the pressure plate 5 to rise vertically along the guide direction of the micro slider 8 until the pressure plate 5 is raised above the reference processing material 12. At this time, the drive motor 7 restarts, the belt assembly rotates, and the processed reference processing material 12 is transported downstream of the equipment, completing one processing cycle.

[0044] Furthermore, the directions or positional relationships described in this utility model are based on the directions or positional relationships shown in the accompanying drawings. They are only for the purpose of facilitating the description of this utility model and simplifying the description, and are not intended to indicate or imply that the device or structure referred to must have a specific orientation, or to operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
