Description

Technical Field

[0001] This application relates to the field of clamping technology, and more specifically, to a board clamping mechanism for furniture production. Background Technology

[0002] Furniture board clamping mechanisms are specialized devices used in furniture manufacturing to firmly fix boards in place, ensuring that the boards remain in a precise position and preventing displacement during processing steps such as cutting, drilling, and grinding, thereby guaranteeing processing accuracy and product quality.

[0003] Traditional clamping methods are difficult to quickly align vertical plates and require additional support and complex measurement and angle adjustment, making the operation cumbersome. When faced with vertical plates of different thicknesses, traditional clamping mechanisms are difficult to adaptively adjust the clamping angle and pressure, which can easily lead to uneven force on the plate and local deformation, affecting processing quality and production efficiency.

[0004] In view of this, this application proposes a board clamping mechanism for furniture production. Utility Model Content

[0005] The purpose of this application is to provide a board clamping mechanism for furniture production, which solves the technical problems mentioned in the background art.

[0006] This application provides a board clamping mechanism for furniture production, including a positioning plate. Limiting plates are fixedly connected to both sides below the front end face of the positioning plate, and the two limiting plates are vertically distributed. A clamping assembly is provided in front of the positioning plate. The clamping assembly includes a fixed frame located above the front end of the positioning plate, and a movable frame located below the fixed frame. Pressing plates are fixedly connected to both side walls of the movable frame. The pressing plates and limiting plates are parallel to each other, and the rear end face of the pressing plate is in contact with the front end face of the positioning plate. A first swing block is rotatably provided inside the fixed frame, and a second swing block is rotatably provided inside the movable frame. A threaded rod is rotatably connected through the first swing block via a threaded connection, and the lower end of the threaded rod is rotatably connected to the movable frame.

[0007] Optionally, the first swing block and the second swing block are symmetrically fixedly connected to an extension block, one end of which is rotatably connected to a fixed cylinder, and multiple fixed cylinders are respectively fixedly connected through the fixed frame and the movable frame.

[0008] Optionally, a torsion spring is fitted onto the outer wall of the extension block.

[0009] Optionally, one end of the torsion spring is fixedly connected to the extension block, and the other end of the torsion spring is fixedly connected to the fixed cylinder.

[0010] Optionally, a fixing block is fixedly connected above the front end face of the positioning plate, and the fixing frame is fixedly connected to the fixing block.

[0011] Optionally, mounting openings are provided on both sides above the front end face of the positioning plate, and a rotating block is fixedly connected to the upper end of the threaded rod.

[0012] One or more technical solutions provided in this application have at least the following technical effects or advantages:

[0013] This application uses a positioning plate spanning the top of two vertically joined panels, with side limiting plates abutting against the outer walls of the panels, forming an "L-shaped" vertical positioning frame. This eliminates the need for excessive support and allows for quick alignment of the panels' verticality by measuring angles. The rotating threaded rod drives the moving frame and pressing plates to move synchronously. Two pressing plates parallel to the limiting plates apply pressure from the inside of the panels, creating a bidirectional compression with the outer limiting plates, generating a stable clamping force. Furthermore, this mechanism is simple to use and significantly improves operational efficiency.

[0014] When clamping vertical plates of different thicknesses, the moving frame shifts to one side due to the thickness difference, causing the first swing block, the second swing block, and the threaded rod to swing synchronously. At the same time, the pressing plate on the moving frame gradually comes into contact with the plate. This continues until the pressing plate completely covers the contact surface of the plate, effectively dispersing pressure and preventing deformation or damage to thin plates due to excessive localized force.

[0019] The present application will be further described in detail below with reference to the accompanying drawings.

[0020] Reference Figures 1-3This application provides a board clamping mechanism for furniture production, including a positioning plate 1. Limiting plates 3 are fixedly connected to both sides below the front end of the positioning plate 1, and the two limiting plates 3 are vertically distributed. A clamping assembly 5 is provided in front of the positioning plate 1. The clamping assembly 5 includes a fixed frame 501 located above the front end of the positioning plate 1, and a movable frame 502 located below the fixed frame 501. Pressing plates 503 are fixedly connected to both side walls of the movable frame 502. The pressing plates 503 and the limiting plates 3 are parallel to each other, and the rear end face of the pressing plate 503 is in contact with the front end face of the positioning plate 1. A first swing block 504 is rotatably provided inside the fixed frame 501, and a second swing block 505 is rotatably provided inside the movable frame 502. A threaded rod 506 is rotatably connected through the first swing block 504 via a thread, and the lower end of the threaded rod 506 is rotatably connected to the movable frame 502. The positioning plate 1 spans the top of two vertically joined boards, and the limiting plates 3 on both sides abut against the outer wall of the boards, forming an "L" shape. The "type" vertical positioning frame requires minimal support and can quickly align the verticality of the sheet material by measuring the angle. The rotation of the threaded rod 506 drives the moving frame 502 and the pressing plate 503 to move synchronously. The two pressing plates 503, which are parallel to the limiting plate 3, apply pressure from the inside of the sheet material, forming a bidirectional compression with the outer limiting plate 3, generating a stable clamping force. At the same time, this mechanism is simple to use and significantly improves operational efficiency.

[0021] The first swing block 504 and the second swing block 505 are symmetrically fixedly connected to an extension block 509. One end of the extension block 509 is rotatably connected to a fixed cylinder 508, and multiple fixed cylinders 508 are respectively fixedly connected through the fixed frame 501 and the moving frame 502. The outer wall of the extension block 509 is fitted with a torsion spring 510. One end of the torsion spring 510 is fixedly connected to the extension block 509, and the other end of the torsion spring 510 is fixedly connected to the fixed cylinder 508. When clamping vertical plates of different thicknesses, the moving frame 502 shifts to one side due to the difference in plate thickness, causing the first swing block 504, the second swing block 505 and the threaded rod 506 to swing synchronously. At the same time, the pressing plate 503 on the moving frame 502 gradually adheres to the plate. The pressure plate 503 can completely cover the contact surface of the plate, effectively dispersing the pressure and preventing the thin plate from deforming or breaking due to excessive local force. The torsion spring 510 plays a good reset role. After use, it drives the first swing block 504, the second swing block 505 and the threaded rod 506 back to the initial position for easy use later.

[0022] A fixing block 4 is fixedly connected to the upper part of the front end face of the positioning plate 1, and the fixing frame 501 is fixedly connected to the fixing block 4. Mounting ports 2 are opened on both sides of the upper part of the front end face of the positioning plate 1. A rotating block 507 is fixedly connected to the upper end of the threaded rod 506. By using bolts to pass through the mounting ports 2, the positioning plate 1 can be fixed to the designated position, which is convenient for the staff to position and use.

[0023] Working principle: When two boards need to be vertically fixed together, the two boards are first vertically spliced ​​together, the positioning plate 1 is placed on the two boards, and the two limiting plates 3 abut against the two boards. The pressing plates 503 on both sides of the moving frame 502 are located inside the two boards. The operator rotates the rotating block 507, which drives the threaded rod 506 to rotate. Since the rear end face of the pressing plate 503 is in contact with the front end face of the positioning plate 1, the threaded rod 506 rotates in the first swing block 504, which drives the second swing block 505 and the moving frame 502 to move synchronously. After the moving frame 502 moves, it drives the pressing plate 503 to move until the two pressing plates 503 firmly abut against the boards, clamping and fixing the boards, thus facilitating the operator to fix the two boards.

[0024] When the two plates have different thicknesses, the limiting plate 3 is first placed against the outer wall of the two plates. Since the first swing block 504 and the second swing block 505 can rotate in the fixed frame 501 and the moving frame 502 respectively, when the two pressing plates 503 on the moving frame 502 come into contact with the plates, the difference in thickness of the plates will cause the moving frame 502 and the pressing plates 503 to deviate in direction, causing the first swing block 504, the second swing block 505 and the threaded rod 506 to swing synchronously. The swing of the first swing block 504 and the second swing block 505 will drive the extension block 509 to rotate in the fixed cylinder 508. The torsion spring 510 on the outer wall of the extension block 509 will deform and generate elastic force. The moving frame 502 will move and rotate until the two pressing plates 503 can fully adhere to the inner wall of the plates, making the plates clamped and fixed more firmly. After securing, loosen the threaded rod 506. Under the elastic force of the torsion spring 510, the first swing block 504, the second swing block 505, and the threaded rod 506 return to their initial positions for easy use next time.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
