Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of wood veneer fixing clamps, and in particular to a novel adjustable wood veneer fixing clamp. Background Technology
[0002] Adjustable wood veneer clamps are auxiliary tools designed specifically for woodworking workbenches. They are used to stably fix wood veneers (such as solid wood boards, plywood, MDF, etc.) during processing, ensuring that they remain accurately positioned when cutting, sanding, carving, or painting, and preventing displacement or vibration from affecting processing accuracy.
[0003] The publication number CN212072269U discloses a new type of fixing device that presses the wooden board onto the table surface by pressing down. Compared with the traditional spring clip, the fixing effect is better. The fixing device can slide along the track and is suitable for wooden boards of different widths. It avoids the wooden board from falling off the clamp during processing and affects the processing process, and the processing process is safer.
[0004] Existing wood veneer fixing clamps are mostly unidirectional or single-point clamping, which cannot achieve synchronous pressure on all four sides. This causes the boards to easily shift or warp during processing, affecting accuracy. Most clamps have a fixed height, making it difficult to adapt to boards of different thicknesses. Frequent clamp replacements or manual shims are required, which is inefficient. Manual adjustment relies on experience, is cumbersome and inconsistent, and can easily cause uneven clamping force. Utility Model Content
[0005] The purpose of this utility model is to provide a novel adjustable wood veneer fixing clamp. The adjustment mechanism design allows it to adapt to boards of different thicknesses and sizes, eliminating the need for frequent clamp replacements, significantly improving work efficiency and reducing tool costs. The integrated clamping mechanism simplifies the traditional multi-step fixing process, reduces manual intervention time, and is especially suitable for mass production scenarios.
[0006] To achieve the above objectives, a novel adjustable wood veneer fixing clamp is provided, comprising a fixing plate with a limiting groove inside. A rotating plate is provided at the upper end of the fixing plate. A movable strip is movably fitted on one side of the rotating plate. A limiting post is fixedly connected to the other side of the movable strip. An upper clamping plate is fixedly connected to the upper end of the limiting post. A lower clamping plate is movably fitted on the outer surface of the limiting post. A worktable is fixedly connected to the upper end of the fixing plate. A limiting block is fixedly connected to the edge of the fixing plate. A movable post is movably fitted inside the limiting block. A lifting plate is movably fitted to the lower end of the fixing plate. A fixing block is fixedly connected to the edge of the lifting plate. A fixing ring is fixedly connected inside the fixing block. A notch is provided on one side of the fixing ring.
[0007] According to the novel adjustable wood veneer fixing clamp, the fixing plate has four limiting grooves inside, the lower end of the moving strip is provided with a lower limiting post, and the lower limiting post of the moving strip is slidably connected inside the limiting groove.
[0008] According to the novel adjustable wood veneer fixing clamp, a motor is fixedly connected inside the fixing plate, a fixed shaft is fixedly connected inside the rotating plate, and a motor output end is fixedly connected inside the fixed shaft.
[0009] According to the novel adjustable wood veneer fixing fixture, the workbench has four through slots inside, and limit posts are set inside the through slots.
[0010] According to the novel adjustable wood veneer fixing clamp, a hydraulic press is fixedly connected to the lower end of the lifting plate, a fixing frame is fixedly connected to the lower end of the hydraulic press, support frames are fixedly connected to the four edges of the fixing frame, a fixing groove is opened inside the support frame, a telescopic column is fixedly connected inside the fixing groove, and a lifting plate is fixedly connected to the upper end of the telescopic column.
[0011] According to the novel adjustable wood veneer fixing clamp, a slide rail is fixedly connected to one side of the limiting post, and a lower clamping plate is slidably connected to the other side of the slide rail.
[0012] According to the novel adjustable wood veneer fixing clamp, an electric telescopic rod is fixedly connected between the moving strip and the lower clamping plate.
[0013] Beneficial effects:
[0014] 1. The fixed plate has a limiting groove inside, and a rotating plate is set at the upper end of the fixed plate. A moving strip is movably fitted on one side of the rotating plate, and a limiting post is fixedly connected to the other side of the moving strip. An upper clamping plate is fixedly connected to the upper end of the limiting post. Through the dual action of simultaneous fixing on all four sides and clamping from top to bottom, the offset or deformation of the board caused by single-point pressure of traditional clamps is effectively avoided. It is especially suitable for processing wood veneer that is prone to warping, ensuring processing accuracy. The adjustment mechanism design allows it to adapt to boards of different thicknesses and sizes without frequent clamp changes, significantly improving work efficiency and reducing tooling costs. The integrated clamping mechanism simplifies the traditional multi-step fixing process and reduces manual intervention time, making it especially suitable for mass production scenarios.
[0015] 2. A worktable is fixedly connected to the upper end of the fixed plate, and a limit block is fixedly connected to the edge of the fixed plate. A movable column is movably fitted inside the limit block. A lifting plate is movably fitted to the lower end of the fixed plate, and a fixed block is fixedly connected to the edge of the lifting plate. A fixed ring is fixedly connected inside the fixed block. The height of the fixture can be quickly adjusted through the lifting function. The lifting mechanism is designed to be stable, ensuring no settling or shaking during processing and guaranteeing processing accuracy. The modular design allows the fixture to be seamlessly connected with other processing equipment to form an automated production line and reduce equipment modification costs.

[0030] The fixed plate 4 has a motor 8 fixedly connected inside, the rotating plate 11 has a fixed shaft 9 fixedly connected inside, and the fixed shaft 9 has the output end of the motor 8 fixedly connected inside.
[0031] Specifically: The output end of motor 8 is fixedly connected to a fixed shaft 9 to provide output, and the rotation of fixed shaft 9 drives the rotating plate 11 to rotate.

When the moving bar 10 moves, it drives the upper limiting post 3 to move and clamp the sheet metal. After clamping the sheet metal, the lower electric telescopic rod 16 starts to work, moving the lower clamping plate 7 upward to achieve the purpose of clamping the sheet metal. When the height of the worktable 2 is insufficient, the lower hydraulic press 18 starts to work. The lifting plate 5 is moved upward to raise the worktable 2. The telescopic column 17 inside the support frame 6 can stabilize the lifting plate 5 as it rises. When the height is too high, the fixed plate 4 can be removed for processing. When the plate is processed, the electric telescopic rod 16 is lowered to release the plate. The motor 8 is reversed to remove the processed plate. When the clamping device is not needed, the movable column 23 is twisted so that the protrusion at the lower end is aligned with the notch of the fixed ring 20. The movable column 23 is lifted upward so that the protrusion passes through the fixed ring 20 to remove the clamping device at the upper end.
