Description

Technical Field

[0001] This utility model relates to the field of ancient building restoration, and in particular to a wood sanding device. Background Technology

[0002] Wood polishing for ancient building restoration refers to the specialized surface treatment technology used in the protection and restoration of ancient buildings to replace, repair, or reinforce wooden components. This process involves using professional tools and techniques to refine the surface of newly processed wood, removing processing marks, burrs, stains, and other surface defects, ensuring that the wood maintains consistency and harmony with the original wooden components of the ancient building in terms of texture, color, and grain.

[0003] Traditionally, sanding construction timber involves manual labor to push the timber into contact with the sanding wheel. When the timber is large, two people are needed: one to control the sanding wheel and the other to push the timber. This method is affected by factors such as the operator's pushing force, speed, and stability. In batch sanding, the pushing distance is not precise enough, and the boards often need to be sanded repeatedly, resulting in poor sanding consistency. Furthermore, manually pushing the timber requires a significant amount of physical strength and energy from the operator.

[0004] Therefore, a wood sanding device for construction is proposed to solve the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a building wood sanding device with multi-axis precision sanding, which can adapt to building boards of various specifications and sizes and sand them efficiently.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

A support frame is jointly supported on two adjacent guide rail sliders on the same side, and a second linear screw module is jointly installed between the two sets of support frames.

[0009] The second linear screw module is horizontally arranged and is equipped with a slider. A third linear screw module is mounted on the side of the slider. The third linear screw module is vertically arranged and is equipped with a sliding block. An electrically controlled grinding mechanism is mounted on the side of the sliding block.

[0010] The CNC grinding machine has two sets of linear slide rails mounted parallel to each other on both sides of its upper end face. Each set of linear slide rails has a slider seat slidably mounted on it, and each set of linear slide rails also has a positioning seat fixedly mounted on it. Each of the two slider seats and the two positioning seats has a plate positioning mechanism mounted on its upper end face.

[0011] Furthermore, the plate positioning mechanism includes a bottom clamping seat and an upper clamping seat. Both the bottom clamping seat and the upper clamping seat are L-shaped. Three holes are opened through each of the opposite sides of the bottom clamping seat and the upper clamping seat. A light rod is inserted into each of the two holes on the bottom clamping seat, and the upper clamping seat slides outside the two light rods.

[0012] Furthermore, a bearing is installed in the hole located in the middle of the bottom clamping seat, and a threaded screw is rotatably connected to the bearing.

[0013] Furthermore, the threaded screw passes through the hole in the middle of the upper clamping seat and is threadedly connected to it, and the top end of the threaded screw passes through the upper clamping seat and extends to be connected to an adjustment handle.

[0014] Furthermore, both the bottom clamping seat and the upper clamping seat have clamping notches on opposite sides.

It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0024] First embodiment;

[0025] Reference Figure 1-3 As shown, a preferred embodiment of the present invention is a wood sanding device for construction, which includes a CNC sanding machine tool 1.

[0026] The CNC grinding machine tool 1 is equipped with side guide rails 2 on both sides. Two sets of guide rail sliders 3 are slidably mounted on the guide rails 2 on both sides. A support frame 5 is jointly supported on the two adjacent guide rail sliders 3 on the same side. A second linear screw module 6 is jointly installed between the two sets of support frames 5.

[0027] The second linear screw module 6 is horizontally arranged and is equipped with a slider. The third linear screw module 7 is mounted on the side of the slider. The third linear screw module 7 is vertically arranged and is equipped with a sliding block. The side of the sliding block is equipped with an electrically controlled grinding mechanism 8.

[0028] Two sets of linear slide rails 9 are mounted parallel to each other on both sides of the upper end face of the CNC grinding machine tool 1. A slider seat 92 is slidably mounted on each set of linear slide rails 9. A positioning seat 91 is also fixedly mounted on each set of linear slide rails 9. A plate positioning mechanism 10 is mounted on the upper end face of the two slider seats 92 and the two positioning seats 91.

[0029] In this embodiment, the wood sanding device achieves high-precision three-dimensional positioning control for sanding operations through the coordinated operation of a triple linear screw module. Compared with traditional manual sanding methods, the automated control of the CNC system significantly improves production efficiency, reducing the sanding time for a single piece of wood to 30-40% of the traditional method. It also eliminates the instability of manual operation, ensuring the consistency of product quality in mass production. The quick-clamping design and slide rail adjustment function of the board positioning mechanism 10 shorten the clamping time for wood of different specifications to 2-3 minutes, greatly improving equipment utilization and overall production efficiency.

[0030] It should be noted that the electrically controlled grinding mechanism 8 is existing technology, which uses a motor to drive the grinding head to rotate, thereby completing the grinding operation.

[0031] Second embodiment;

[0032] Reference Figure 2-3 As shown, the plate positioning mechanism 10 includes a bottom clamping seat 101 and an upper clamping seat 103. Both the bottom clamping seat 101 and the upper clamping seat 103 are L-shaped. Three holes are opened through each side of the bottom clamping seat 101 and the upper clamping seat 103. A light rod 102 is inserted into two holes on the bottom clamping seat 101, and the upper clamping seat 103 slides outside the two light rods 102.

[0033] In this embodiment, both the bottom clamping seat 101 and the upper clamping seat 103 are L-shaped to accommodate the clamping requirements of plates with different shapes. Each clamping seat has three precisely positioned holes on its opposite side, forming a regular connection and guiding system. The guide rod 102, inserted into the two holes on the bottom clamping seat 101, serves a dual function of guidance and support, ensuring that the upper clamping seat 103 can slide smoothly outside the guide rod 102, avoiding offset and swaying during the clamping process.

[0034] Third embodiment;

[0035] Reference Figure 2-3 As shown, a bearing is installed in the hole in the middle of the bottom clamping seat 101, and a threaded screw 104 is rotatably connected to the bearing.

[0036] In this embodiment, the bearing assembly installed in the central hole of the bottom clamping seat 101 constitutes the core support component of the threaded transmission system. The smooth rotation of the threaded screw 104 is achieved through the precise rotational connection of the bearing assembly. The use of the bearing assembly significantly reduces the frictional resistance when the threaded screw 104 rotates.

[0037] Fourth embodiment;

[0038] Reference Figure 2-3As shown, the threaded screw 104 passes through the hole in the middle of the upper clamping seat 103 and is threadedly connected to it. The top end of the threaded screw 104 passes through the upper clamping seat 103 and extends to be connected to the adjusting handle 105.

[0039] In this embodiment, the adjusting handle 105, which extends through the upper clamping seat 103 and is connected to the threaded screw 104, provides a convenient manual control interface for the operator. By rotating the adjusting handle 105, the up and down movement of the upper clamping seat 103 can be precisely controlled, thereby achieving adaptive clamping of plates of different thicknesses.

[0040] Fifth embodiment;

[0041] Reference Figure 2-3 As shown, clamping notches 106 are provided on opposite sides of both the bottom clamping seat 101 and the upper clamping seat 103.

[0042] In this embodiment, the clamping notches 106 formed on opposite sides of the bottom clamping seat 101 and the upper clamping seat 103 constitute a dedicated space for accommodating and positioning the board. This notch design fully considers the geometric characteristics and clamping requirements of boards of different specifications. The shape and size of the clamping notch 106 are carefully designed to accommodate standard thickness construction timber and to effectively clamp irregularly shaped boards through the relative movement of the upper and lower clamping seats.

[0043] Sixth embodiment;

[0044] Reference Figure 1 As shown, a first linear screw module 4 is assembled on the CNC grinding machine tool 1, and a sliding seat is assembled on the first linear screw module 4, and the sliding seat is connected to two guide rail sliders 3.

[0045] In this embodiment, the first linear screw module 4 assembled on the CNC grinding machine tool 1 constitutes the main power transmission mechanism of the entire grinding system, providing a reliable driving force source for the precise movement of the guide rail slider 3.

[0046] Specific implementation process: The operation of the construction timber sanding device begins with the precise positioning and reliable clamping of the timber. The operator places the construction timber to be sanded onto the worktable of the CNC sanding machine 1. By adjusting the positions of the slider seats 92 on the two sets of linear guide rails 9, the board positioning mechanism 10 can adapt to different timber lengths. At this point, the L-shaped structure design of the bottom clamping seat 101 and the upper clamping seat 103 plays a crucial role. The clamping notches 106 on opposite sides of both provide a standardized positioning reference for the timber. The operator rotates the adjusting handle 105, driving the threaded screw 104 to rotate smoothly under the support of the bearing components. The threaded connection between the threaded screw 104 and the central hole of the upper clamping seat 103 allows the upper clamping seat 103 to descend precisely along the two guide rods 102 until the clamping notches 106 are tightly fitted against the timber surface. The guiding effect of the two guide rods 102 ensures the linearity and stability of the clamping action, avoiding lateral deviation.

[0047] Step 2: After the wood is reliably clamped, the intelligent control system of the CNC grinding machine 1 begins to execute the preset grinding program, and the first linear screw module 4 starts working as the main drive mechanism. Under the precise drive of the first linear screw module 4, the sliding seat synchronously drives the sliders 3 on both sides of the guide rail 2 to move longitudinally through mechanical connection, realizing the precise positioning of the grinding system in the length direction of the wood. The support frame 5, jointly supported by the two adjacent guide rail sliders 3 on the same side, maintains the rigidity and stability of the system. The second linear screw module 6 installed between the two sets of support frames 5 is horizontally set, and its configured slider can move precisely in the lateral range, thereby realizing full coverage scanning in the width direction of the wood. The third linear screw module 7 installed on the side of the slider of the second linear screw module 6 is vertically set, and its configured sliding block realizes the vertical height adjustment. The establishment of this three-dimensional coordinate system enables the electronically controlled grinding mechanism 8 to move freely in three-dimensional space according to the pre-programmed trajectory, ensuring that the grinding head can accurately reach every specified position on the surface of the wood, laying a solid positioning foundation for subsequent precision grinding operations.

[0048] Step 3: After the 3D positioning system completes its initial setup, the electrically controlled sanding mechanism 8, installed on the side of the sliding block of the third linear screw module 7, begins to perform the specific sanding operation. The CNC system automatically adjusts the rotational speed, feed rate, and downward pressure of the sanding mechanism 8 according to the material characteristics, surface condition, and processing requirements of the wood, ensuring consistent sanding results and uniform surface quality. During the sanding process, the first linear screw module 4, the second linear screw module 6, and the third linear screw module 7 work in coordination to achieve precise linkage of the sanding head in the X, Y, and Z directions, enabling various complex processing operations such as flat sanding, edge trimming, and chamfering. The board positioning mechanism 10 maintains stable clamping of the wood throughout the sanding process, and the cooperative use of the positioning seat 91 and the slider seat 92 ensures reliable support for wood of different lengths.
