Abstract
Description
Technical Field
[0001] This utility model relates to the field of mortise and tenon processing, and in particular to a mortise and tenon joint processing device for wooden boards. Background Technology
[0002] Mortise and tenon joints, as a core technology of traditional woodworking, are widely used in furniture manufacturing, building structures, and wooden decoration. Their advantage lies in achieving a stable joint without the need for metal connectors, combining aesthetics and mechanical performance. However, current mortise and tenon processing requires drilling during the process, and existing mortise and tenon processing equipment has significant shortcomings in terms of wood clamping and drilling accuracy, specifically manifested in the following problems:
[0003] Traditional methods rely on planar clamps or vacuum adsorption tables to fix boards using pressure plates or screws, but these methods cannot effectively clamp cylindrical wood, easily leading to the wood rolling or shifting during processing. Furthermore, existing mortise and tenon processing equipment typically only supports drilling in vertical or horizontal directions, unable to process mortises or grooves at inclined angles (such as 30° or 45°). Based on these limitations, we propose a mortise and tenon joint processing device for wood-based panels. Utility Model Content
[0004] To address the technical problems of insufficient clamping adaptability and inability to drill at an angle, this utility model provides a mortise and tenon joint processing device for wood panels.
[0005] This utility model is achieved using the following technical solution: a mortise and tenon joint processing device for wood panels, including a support frame, a mounting platform connected to the top of the support frame, a multi-angle adjustable drill bit mechanism and a wood positioning mechanism installed above the mounting platform; wherein, the multi-angle adjustable drill bit mechanism includes a connecting platform, a support platform fixedly connected above the connecting platform, an electric push rod connected to the outside of the support platform, a drill bit connected to the top of the electric push rod, a slotting drill bit connected to the drill bit, a locking bolt installed on the surface of the connecting platform, a scale plate connected to the bottom of the connecting platform, the connecting platform and the scale plate being tightly engaged by the locking bolt, the scale plate having graduations on its surface, and the scale plate being fixedly connected to the surface of the mounting platform.
[0006] The timber positioning mechanism includes a fixed base, which is fixedly installed on the surface of the mounting platform. A rotating screw is threaded through the surface of the fixed base. One end of the rotating screw is connected to a handle, and the other end of the rotating screw is rotatably connected to a sliding seat. Both the upper and lower ends of the fixed base are connected to sliding rods, which slide through the ends of the sliding seats. One end of a receiving rod is fixedly connected to the surface of the sliding seat, and the other end of the receiving rod is connected to an active clamping plate. The surface of the active clamping plate has an active clamping plate slot.
[0007] There are two sets of active clamping plates, which are set on both sides of the sliding seat via a receiving rod; there are also two sets of driven clamping plates, which are installed on both sides of the fixed frame.
[0008] The timber positioning mechanism drives the sliding seat to move along the slide rod by rotating the screw, which in turn moves the receiving rod and the active clamping plate towards the driven clamping plate. The design of the slide rod and the fixed frame ensures smooth movement of the sliding seat and avoids displacement caused by uneven force during clamping.
[0009] The bottom end of the slide bar is connected to a fixed frame, and the surface of the fixed frame is bolted with driven clamps. The surface of the driven clamps has driven clamp slots. There are two sets of active clamps, which are set on both sides of the receiving rod via a receiving rod; there are also two sets of driven clamps, which are installed on both sides of the fixed frame.
[0010] As a further improvement to the above solution, loosen the locking bolts and rotate the connecting table to the preset angle of the dial (such as 30° or 45°) to accurately align the target tilt angle through the scale; the intuitive angle calibration of the dial and the one-click locking of the locking bolts simplify the tilting drilling process and lower the operation threshold.
[0011] As a further improvement to the above solution, tighten the locking bolts to fix the relative position of the connecting platform and the dial, ensuring the stability of the drill bit's tilt angle.
[0012] As a further improvement to the above solution, the electric push rod drives the drill bit to extend, adjusting the feed depth of the grooving drill bit to adapt to different mortise and tenon size requirements. The drill bit is then started, and it cuts into the wood at a preset angle to complete the machining of the inclined hole for the inclined mortise or groove.
[0013] As a further improvement to the above solution, the triangular teeth on the surfaces of the active clamping plate and the driven clamping plate can engage the curved surface of cylindrical wood or the edge of slab wood, and disperse pressure through the inclined tooth area to prevent the wood from rolling or slipping.
[0014] As a further improvement to the above scheme, two sets of active clamping plates and driven clamping plates are symmetrically arranged to form multi-point clamping, which can be adapted to wood with different cross-sectional shapes, such as round and square, to ensure clamping stability.
[0015] As a further improvement to the above solution, both the active clamping plate and the driven clamping plate have teeth on their surfaces. The teeth are triangular in shape and are used to engage the wood.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0017] 1. This utility model, through the symmetrical layout of the active and driven clamping plates and the concave bayonet design, combined with triangular clamping teeth, can simultaneously and stably clamp cylindrical wood materials such as round wooden pillars and plate-shaped wood materials such as boards, preventing the wood from rolling or slipping. The double-clamping multi-point clamping structure is adaptable to different cross-sectional shapes, significantly improving the clamping versatility and stability.
[0018] 2. This utility model supports the drill bit to be precisely positioned at a preset tilt angle (such as 30° or 45°) through the cooperation of the multi-angle adjustable drill bit mechanism and the scale and locking bolt. The scale clearly marks the angle, ensuring the tilt processing accuracy of the mortise or tenon and meets the needs of complex mortise and tenon structures.
[0019] 3. The wood positioning mechanism of this utility model can quickly adjust the clamping distance by driving the screw through the handle, without the need for tools; the electric push rod automatically controls the feed of the drill bit, and the locking bolt locks the angle with one click, simplifying the operation process and reducing the dependence on the operator's experience.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0026] Example 1:
[0027] Please combine Figures 1-3This embodiment proposes a mortise and tenon joint processing device for wood panels, including a support frame 1, a mounting platform 2 connected to the top of the support frame 1, a multi-angle adjustable drill bit mechanism 3 and a wood positioning mechanism 4 installed above the mounting platform 2; wherein, the multi-angle adjustable drill bit mechanism 3 includes a connecting platform 31, a support platform 32 fixedly connected above the connecting platform 31, an electric push rod 33 connected to the outside of the support platform 32, a drill bit 34 connected to the top of the electric push rod 33, a slotting drill bit 341 connected to the drill bit 34, a locking bolt 35 installed on the surface of the connecting platform 31, a scale 36 connected to the bottom of the connecting platform 31, the connecting platform 31 and the scale 36 are tightly engaged by the locking bolt 35, the surface of the scale 36 is provided with a scale 37, and the scale 36 is fixedly connected to the surface of the mounting platform 2.
[0028] Specifically, loosen the locking bolt 35, rotate the connecting table 31 to the preset angle (such as 30°, 45°) of the dial 36, and accurately align the target tilt angle through the scale 37; the intuitive angle calibration of the dial 36 and the one-click locking of the locking bolt 35 simplify the tilting drilling process and lower the operation threshold.
[0029] Tighten the locking bolt 35 to fix the relative position of the connecting platform 31 and the dial 36, ensuring the stability of the tilt angle of the drill bit 34.
[0030] More specifically, the electric push rod 33 drives the drill bit 34 to extend, adjusting the feed depth of the grooving drill bit 341 to adapt to different mortise and tenon size requirements. When the drill bit 34 is started, the grooving drill bit 341 cuts into the wood at a preset angle to complete the machining of the inclined hole for the inclined mortise or groove.
[0031] The timber positioning mechanism 4 includes a fixed seat 41, which is fixedly installed on the surface of the mounting platform 2. A rotating screw 42 is threaded through the surface of the fixed seat 41. One end of the rotating screw 42 is connected to a handle 43, and the other end of the rotating screw 42 is rotatably connected to a sliding seat 44. Both the upper and lower ends of the fixed seat 41 are connected to sliding rods 45, which slide through the end of the sliding seat 44. One end of a receiving rod 46 is fixedly connected to the surface of the sliding seat 44, and the other end of the receiving rod 46 is connected to an active clamping plate 47. An active clamping plate slot 48 is provided on the surface of the active clamping plate 47.
[0032] Furthermore, two sets of active clamping plates 47 are provided, and the two sets of active clamping plates 47 are provided on both sides of the sliding seat 44 via the receiving rod 46; two sets of driven clamping plates 410 are provided, and the two sets of driven clamping plates 410 are installed on both sides of the fixed frame 49.
[0033] Furthermore, the timber positioning mechanism 4 drives the sliding seat 44 to move along the sliding rod 45 by rotating the screw 42, thereby pushing the receiving rod 46 and the active clamping plate 47 towards the driven clamping plate 410. The cooperative design of the sliding rod 45 and the fixing frame 49 ensures that the sliding seat 44 moves smoothly and avoids deviation caused by uneven force during clamping.
[0034] Furthermore, a fixed frame 49 is connected to the bottom end of the slide rod 45, and a driven clamp 410 is bolted to the surface of the fixed frame 49. A driven clamp slot 411 is provided on the surface of the driven clamp 410.
[0035] Furthermore, the triangular teeth 412 provided on the surfaces of the active clamping plate slot 48 and the driven clamping plate slot 411 can engage the curved surface of cylindrical wood or the edge of plate-shaped wood, and disperse pressure by tilting the tooth area to prevent the wood from rolling or slipping.

[0038] Furthermore, both the active clamping plate latch 48 and the driven clamping plate latch 411 are provided with locking teeth 412, which are triangular in shape and used to engage the wood.
[0039] The mortise and tenon joint processing device for wood panels described in this utility model solves the technical problem that traditional equipment cannot be compatible with clamping cylindrical / panel wood materials and tilting drilling by integrating an adaptive clamping mechanism and a multi-angle adjustable drill bit system. The specific working principle is as follows:
[0040] 1. Adaptive clamping of multi-shaped wood
[0041] The timber positioning mechanism 4 drives the sliding seat 44 to move along the sliding rod 45 by rotating the screw 42, which in turn drives the receiving rod 46 and the active clamping plate 47 to move towards the driven clamping plate 410. The design of the sliding rod 45 and the fixed frame 49 ensures that the sliding seat 44 moves smoothly and avoids displacement caused by uneven force during clamping.
[0042] U-shaped latch and triangular teeth design: The triangular teeth 412 provided on the surfaces of the active clamping plate latch 48 and the driven clamping plate latch 411 can engage the curved surface of cylindrical wood or the edge of plate-shaped wood. The pressure is distributed by the inclined tooth area to prevent the wood from rolling or slipping.
[0043] Symmetrical layout of double clamping plates: Two sets of active clamping plates 47 and driven clamping plates 410 are symmetrically arranged to form multi-point clamping, which can adapt to wood with different cross-sectional shapes such as round and square, and ensure clamping stability.
[0044] 2. Precise tilt angle adjustment and drilling
[0045] Operation procedure of multi-angle adjustable drill bit mechanism 3:
[0046] Angle calibration: Loosen the locking bolt 35, rotate the connecting table 31 to the preset angle (such as 30°, 45°) on the dial 36, and accurately align the target tilt angle through the scale 37; the intuitive angle calibration of the dial 36 and the one-click locking of the locking bolt 35 simplify the tilting drilling process and lower the operation threshold.
[0047] Angle locking: Tighten the locking bolt 35 to fix the relative position of the connecting platform 31 and the dial 36, and ensure that the tilt angle of the drill bit 34 is stable;
[0048] Drill bit position adjustment: The electric push rod 33 drives the drill bit 34 to extend, adjusting the feed depth of the grooving drill bit 341 to adapt to different mortise and tenon size requirements. Start the drill bit 34, and the grooving drill bit 341 cuts into the wood at a preset angle to complete the machining of the inclined hole for the inclined mortise or groove.
