Description

Technical Field

[0001] This utility model relates to the field of machining equipment, and more specifically to a side clamping assembly for a gantry grooving machine. Background Technology

[0002] Large quantities of metal sheets are used in the decoration of shopping malls, airports, restaurants, hotels, banks, and other commercial buildings. These sheets need to be bent, and to achieve a smaller radius of curvature and a more aesthetically pleasing appearance, grooving is necessary before bending. Machine tools for grooving thin metal sheets are typically divided into vertical and gantry types. Chinese Utility Model Patent 20615200461942.1 discloses an automatic rotary tool holder device for a gantry-type thin plate grooving machine, which achieves grooving in both longitudinal and transverse directions through the rotation of the tool holder. However, in actual production, while the first pressure foot assembly clamps the metal sheet during longitudinal grooving, the technical problem of clamping the metal sheet during transverse grooving remains unresolved. To clamp the metal sheet for transverse grooving, a row of pressure foot assemblies needs to be added to the side of the machine tool base.

[0003] Existing side presser feet still have the following drawbacks: 1. Using a lead screw to drive all side presser feet to move together, when the distance to be moved is greater than the spacing between adjacent presser foot assemblies, it is impossible to meet the grooving requirements by moving the presser feet; 2. The overall cost of the lead screw and motor is relatively high; 3. Because the lead screw is exposed, metal shavings are easily caused to fall onto the lead screw, causing it to jam.

[0004] Chinese utility model patent: Side clamping assembly for gantry-type four-sided grooving machine, patent number: 2022219287431 proposed an improvement, but feedback from actual market use still shows the following defects: 1. Cutting debris will fall from the processing table onto the transmission belt. If water gets into the belt, the debris will cut the transmission belt, making it unable to move and requiring frequent replacement of the transmission belt. 2. Because belt drives are flexible connections, the pressure feet on the track need to be locked before they can be used. After movement, the pressure feet and lead screws need to be loosened one by one, and then locked one by one after movement, which is a cumbersome process. Summary of the Invention

[0005] To address the aforementioned problems, the purpose of this utility model is to provide a side clamping component for a gantry grooving machine that offers stable lifting and movement, long service life, diverse presser foot movement methods, and convenient operation.

[0006] According to one aspect of this utility model, a side clamping assembly for a gantry grooving machine is provided, comprising: a presser foot component, a moving component, and a driving component. Several presser foot components are provided. The moving component is installed on the side of the grooving machine bed. All presser foot components are mounted on the moving component and can reciprocate on the moving component. The driving component is installed in the lower middle of the moving component. Two presser foot components mounted in the middle of the moving component are fixedly connected to the top of the driving component. The driving component drives all presser foot components to reciprocate on the moving component. The cooperation between the driving component and the moving component facilitates the movement of all or part of the presser foot components, thereby adapting to different grooving requirements.

[0007] In some embodiments, the moving parts include: a linear guide, a slider, and a connecting rod. The linear guide is fixedly installed on the side of the grooving machine body. Several sliders are mounted on the linear guide, and pressure foot assemblies are installed on the sliders. Adjacent pressure foot assemblies are fixed together by connecting rods. The cooperation between the linear guide and the slider ensures smooth movement of the pressure foot assemblies, and the connecting rods connect the pressure foot assemblies into a whole for easy full or partial drive.

[0008] In some embodiments, the driving component includes a motor, a U-shaped channel steel, a rack, and a gear. The motor is fixedly mounted below the linear guide, and a gear is mounted on the output end of the motor. The U-shaped channel steel is fixedly connected to two of the aforementioned presser foot components, and the rack is installed inside the U-shaped channel steel, meshing with the gear. The movement of the presser foot components is achieved by driving the rack and U-shaped channel steel with the motor.

[0009] In some embodiments, the teeth of the rack are positioned downwards, and the two ends of the U-shaped channel are closed. The closed ends of the U-shaped channel and the downward-facing rack prevent metal shavings from falling onto the transmission teeth, resulting in convenient use, long service life, and no need for regular cleaning.

[0010] In some embodiments, the presser foot component includes: a mounting base and a drive member, a presser foot, a first connecting base and a second connecting base disposed on the mounting base. The output end of the drive member is connected to the rear end of the presser foot through a first hinge member, and the front end of the presser foot is hinged to the mounting base through a second hinge member. The first connecting base is disposed on one side of the mounting base, and the second connecting base is disposed on the other side of the mounting base.

[0011] In some embodiments, one end of the connecting rod is inserted and fixed in the first connecting seat, and the other end of the connecting rod is inserted and fixed in the second connecting seat. The connecting rod is fixedly connected to two adjacent presser foot assemblies through the first connecting seat and the second connecting seat.

[0012] In some implementations, the motor is a servo motor; the drive component is a hydraulic cylinder or a pneumatic cylinder.

[0013] Compared with existing technologies, this utility model provides a side clamping assembly for a gantry grooving machine, which offers advantages such as stable movement, long service life, diverse presser foot movement methods, and convenient operation. The cooperation between the drive and moving components facilitates the movement of all or part of the presser foot, adapting to different grooving requirements. The cooperation between the linear guide and the slider ensures smooth movement of the presser foot, and the connecting rod connects the presser foot components into a single unit for easy full or partial drive. The motor drives the rack and U-shaped channel steel to move the presser foot. The closed ends of the U-shaped channel steel and the downward-facing rack prevent iron filings from falling onto the transmission teeth, making it convenient to use, long-lasting, and requiring no fixed cleaning.

Detailed Implementation

[0015] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings. However, it should be noted that these embodiments are not intended to limit the present invention. Equivalent transformations or substitutions in function, method or structure made by those skilled in the art based on these embodiments are all within the protection scope of the present invention.

[0016] In the description of this utility model, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "connection" should be interpreted broadly. For example, they can refer to mechanical or electrical connections, or internal connections between two components. They can be direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the terms according to the specific circumstances.

[0017] like Figure 1 and Figure 2As shown, the side clamping assembly for the gantry grooving machine of this utility model includes: a presser foot component 1, a moving component 2, and a driving component 3. Several presser foot components 1 are provided. The moving component 2 is installed on the side of the grooving machine bed. All presser foot components 1 are mounted on the moving component and can reciprocate on the moving component 2. The driving component 3 is installed in the lower middle of the moving component 2. The top of the driving component 3 is fixedly connected to two presser foot components 1 installed in the middle of the moving component 2. The driving component 3 drives all presser foot components 1 to reciprocate on the moving component 2. The cooperation between the driving component 3 and the moving component 2 facilitates the movement of all or part of the presser foot components 1, thereby adapting to different grooving requirements.

[0018] The moving component 2 includes: a linear guide 21, a slider 22, and a connecting rod 23. The linear guide 21 is fixedly installed on the side of the grooving machine body. Several sliders 22 are mounted on the linear guide 21. Presser foot 13 assemblies are installed on the sliders 22, and adjacent presser foot 13 assemblies are fixed together by the connecting rod 23. The cooperation between the linear guide 21 and the slider 22 ensures smooth movement of the presser foot component 1, and the connecting rod 23 connects the presser foot components 1 into a whole for easy full or partial drive.

[0019] During use, the connecting rod 23 can be used to connect and fix the middle presser foot component 1 as needed. One or more presser foot components 1 at both ends can be connected as a whole without the connecting rod 23, which makes it easier to achieve more pressing needs.

[0020] like Figure 3 and Figure 4 As shown, the driving component 3 includes a motor 31, a U-shaped channel steel 32, a rack 33, and a gear 34. The motor 31 is fixedly installed below the linear guide 21, and the gear 34 is installed at the output end of the motor 31. The U-shaped channel steel 32 is fixedly connected to the two presser foot components 1. The rack 33 is installed inside the U-shaped channel steel 32 and meshes with the gear 34. The motor 31 drives the rack 33 and the U-shaped channel steel 32, thereby realizing the movement of the presser foot components 1.

[0021] The teeth of the rack 33 are positioned downwards, and both ends of the U-shaped channel steel 32 are closed. The closed ends of the U-shaped channel steel 32 and the downward-positioned rack 33 prevent iron filings from falling onto the transmission teeth, making it convenient to use, long-lasting, and requiring no regular cleaning.

[0022] Of course, the opening of the U-shaped channel steel 32 faces downwards. The bolt passes through the top of the U-shaped channel steel 32 and connects to the rack 33. The transmission teeth of the rack 33 face downwards. Because both ends of the U-shaped channel steel 32 are closed, and the rack 33 is positioned downwards, it is possible to prevent iron filings from falling onto the transmission teeth and causing the gear 34 and rack 33 to malfunction. At the same time, compared with existing technologies, it has a long service life and basically does not require maintenance or replacement of transmission components. On the other hand, the meshing of the gear 34 and the rack 33 has a locking effect, so the pressure foot component 1 connected together does not require additional locking operations, reducing the operation process and making it more convenient.

[0023] To better prevent iron filings from falling in, cover plates can be installed on the outside of the moving part 2 and the driving part 3.

[0024] like Figure 5 As shown, the presser foot component 1 includes: a mounting base 11 and a drive component 12, a presser foot 13, a first connecting seat 14, and a second connecting seat 15 disposed on the mounting base 11. The output end of the drive component 12 is connected to the rear end of the presser foot 13 via a first hinge, and the front end of the presser foot 13 is hinged to the mounting base 11 via a second hinge. The first connecting seat 14 is disposed on one side of the mounting base 11, and the second connecting seat 15 is disposed on the other side of the mounting base 11. The upward movement of the drive component 12 is used to press the front end of the presser foot 13 against the metal sheet to fix it in place.

[0025] One end of the connecting rod 23 is inserted and fixed in the first connecting seat 14, and the other end of the connecting rod 23 is inserted and fixed in the second connecting seat 15. The connecting rod 23 is fixedly connected to two adjacent pressure foot 13 assemblies through the first connecting seat 14 and the second connecting seat 15.

[0026] The first connecting seat 14 and the second connecting seat 15 have the same structure, with a connecting hole in the middle. A threaded hole communicating with the connecting hole is provided at the upper or lower part of the connecting hole. The connecting rod 23 is fixed by a bolt passing through the threaded hole and pressing against the connecting rod 23 inside the connecting hole. Grooves can even be provided at both ends of the connecting rod 23. Inserting the end of the fixing bolt into the groove provides a better tightening effect.

[0027] The motor 31 is a servo motor; the drive component 12 is a hydraulic cylinder or a pneumatic cylinder. The servo motor 31 is used to achieve precise movement of the presser foot component 1, and the hydraulic cylinder or pneumatic cylinder is used to provide power to the presser foot component 1. It should be noted that the hydraulic cylinder has a larger pressure and is suitable for cases where the metal plate is thicker and the surface roughness requirement is not high, while the pneumatic cylinder has an adjustable pressure and is more suitable for cases where the metal plate is thinner and the surface roughness requirement is higher.

[0028] The above descriptions are merely some embodiments of this utility model. It should be noted that those skilled in the art can make other modifications and improvements without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
