Description

Technical Field

[0001] This utility model belongs to the field of columnar wood processing technology, and in particular relates to a flexible sanding device for columnar wood. Background Technology

[0002] Currently, in the production and processing of the money stool, columnar wood is required to be processed into accessories. This requires processing the columnar wood, which involves sanding. Currently, a corresponding flexible sanding device is used in the sanding process.

[0003] Existing flexible sanding devices are not convenient for repositioning the sanding parts during actual sanding. As a result, the continuous use of the same position of the sanding parts will cause the debris to accumulate, which will affect the sanding effect. It is not convenient to use the second limit slider to drive the sanding parts to reposition for efficient sanding. Therefore, we propose a columnar wood flexible sanding device. Summary of the Invention

[0004] In view of this, the present invention aims to propose a flexible sanding device for columnar wood to solve the technical problem that it is inconvenient to use a second limiting slider to drive the sanding part to change position.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] A flexible sanding device for columnar wood includes a platform, with movable frames on both sides of the top of the platform. A clamping plate is rotatably installed on the inner wall of one movable frame, and a four-jaw chuck is rotatably installed on the inner wall of the other movable frame. A servo motor is fixedly connected to the outer wall of one of the movable frames, and the drive shaft of the servo motor movably passes through the movable frame and is fixedly connected to the four-jaw chuck.

[0007] A movable rod is connected to one side of the platform, and a lifting plate is connected to one side wall of the movable rod. A second limiting groove is provided at the bottom of the lifting plate. A matching second limiting slider is inserted into the inner cavity of the second limiting groove. A second electric push rod is fixedly connected to one side of the second limiting slider. The outer end of the second electric push rod is fixedly connected to the inner wall of the second limiting groove. A carrier plate is connected to the bottom of the second limiting slider. A sponge block is connected to the bottom of the carrier plate. Sandpaper is connected to the bottom of the sponge block.

[0008] It should be understood that during sanding, the lifting plate is lowered, allowing the sandpaper at the bottom of the sponge block to adhere to the wood surface. Then, the movable rod moves back and forth, enabling the sandpaper to sand the rotating wood. During sanding, the second electric push rod drives the second limit slider to move, allowing the sandpaper to be placed at different positions on the wood surface. This helps prevent debris from accumulating in the same spot and affecting the sanding effect, thus achieving efficient sanding and improving the sanding effect. At the same time, changing the sanding position and the vibration generated during sanding can shake off previously accumulated debris for reuse.

[0009] Furthermore, a rotating shaft is fixedly connected to the top center of the carrier plate, the top of the rotating shaft is rotatably connected to the bottom of the second limiting slider, a torsion spring plate is fixedly fitted on the outer wall of the rotating shaft, and the torsion spring plate is fixedly connected to the bottom of the second limiting slider.

[0010] It should be noted that the vibration generated during the sanding process can cause the sponge block to rotate slightly along the axis of rotation, which helps to drive the sandpaper to rotate axially. This allows for sanding of columnar wood from multiple directions, further improving the sanding effect. Moreover, the axial movement helps to shake off the debris.

[0011] Furthermore, fixing rods are fixedly connected to both sides of the outer wall of the rotating shaft, and limit rods are fixed to the top of the carrier plate on both sides of the fixing rods.

[0012] Furthermore, it also includes a first drive assembly, which is installed in a first sliding cavity opened in the front side wall of the platform. The first drive assembly includes a dual-axis motor, which is fixed in the middle of the inner wall of the first sliding cavity. Both ends of the dual-axis motor are fixedly connected to a first lead screw. The outer end of the first lead screw is rotatably connected to the inner wall of the first sliding cavity. A matching first lead screw slider is fitted on the outer wall of the first lead screw. The outer wall of the first lead screw slider is fixedly connected to the movable frame.

[0013] Furthermore, a second sliding cavity is provided on the back of the platform. A lead screw motor is fixedly installed at one end of the inner cavity of the second sliding cavity. A second lead screw is fixedly connected to the outer end of the drive shaft of the lead screw motor. The outer end of the second lead screw is rotatably connected to the inner wall of the second sliding cavity. A matching second lead screw slider is fitted on the outer wall of the second lead screw. The outer wall of the second lead screw slider is fixedly connected to the movable rod.

[0014] Furthermore, a first limiting groove is provided on the upper side of the inner wall of the movable rod, and a matching first limiting slider is inserted into the inner cavity of the first limiting groove. A first electric push rod is fixedly connected to the bottom of the first limiting slider, and the tail end of the first electric push rod is fixedly connected to the bottom of the inner cavity of the first limiting groove. The outer wall of the first limiting slider is fixedly connected to the lifting plate.

[0015] Furthermore, the outer wall of the clamp is provided with anti-slip texture.

[0016] Compared with the prior art, the flexible sanding device for columnar wood described in this utility model has the following advantages:

[0017] Beneficial effects:

[0018] The flexible sanding device for columnar wood described in this utility model allows for sanding by attaching sandpaper from the bottom of a sponge block to the surface of the columnar wood. After sanding for a certain period of time, a second electric push rod drives a second limiting slider to move, thereby changing the position of the sandpaper to sand the wood surface. This helps to prevent debris from continuously accumulating in the same position and affecting the sanding effect, thus achieving efficient sanding and improving the sanding effect. At the same time, changing the sanding position and the vibration generated during the sanding process can shake off the previously accumulated debris, making it convenient for reuse.

[0019] The flexible sanding device for columnar wood described in this utility model has a carrier plate rotatably connected by a rotating shaft and a second limiting slider. A torsion spring is set on the rotating shaft so that the vibration generated during the sanding process can cause the sponge block to rotate slightly along the axis of the rotating shaft. This facilitates the axial rotation of the sandpaper, which is beneficial for sanding the columnar wood from multiple directions, thereby further improving the sanding effect. Moreover, the existence of an axial movement trajectory helps to shake off the debris. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] like Figure 1-4 As shown in the figure, as an embodiment, a flexible sanding device for columnar wood includes a platform 1. Movable frames 14 are provided on both sides of the top of the platform 1. A clamping plate 15 is rotatably installed on the inner wall of one movable frame 14, and a four-jaw chuck 16 is rotatably installed on the inner wall of the other movable frame 14. A servo motor 17 is fixedly connected to the outer wall of one of the movable frames 14. The drive shaft of the servo motor 17 movably passes through the movable frame 14 and is fixedly connected to the four-jaw chuck 16.

[0032] Specifically, the two movable frames 14 are close to each other to accommodate the length of the columnar wood. Then, the four-jaw chuck 16 is used to clamp and fix one end of the wood, and the other end of the wood is pressed against the clamping plate 15. Then, the servo motor 17 drives the four-jaw chuck 16 to rotate, thereby driving the wood to rotate.

[0033] A movable rod 2 is connected to one side of the platform 1. A lifting plate 23 is connected to one side wall of the movable rod 2. A second limiting groove is provided at the bottom of the lifting plate 23. A matching second limiting slider 27 is inserted into the inner cavity of the second limiting groove. A second electric push rod 28 is fixedly connected to one side of the second limiting slider 27. The outer end of the second electric push rod 28 is fixedly connected to the inner wall of the second limiting groove. A carrier plate 24 is connected to the bottom of the second limiting slider 27. A sponge block 25 is connected to the bottom of the carrier plate 24. Sandpaper 26 is connected to the bottom of the sponge block 25.

[0034] It should be understood that during sanding, the lifting plate 23 is lowered, so that the sandpaper 26 at the bottom of the sponge block 25 adheres to the wood surface. Then, the movable rod 2 moves back and forth, so that the sandpaper 26 can be used to sand the rotating wood. During the sanding process, the second electric push rod 28 drives the second limit slider 27 to move, so that the sandpaper 26 can be changed to different positions to adhere to the wood surface. This helps to avoid the continuous accumulation of debris in the same position, which affects the sanding effect. This helps to achieve efficient sanding and improve the sanding effect. At the same time, changing the sanding position, the vibration generated during the sanding process can shake off the previously accumulated debris, making it convenient for reuse.

[0035] It is worth mentioning that, in order to ensure the stability of the plywood 15 in pressing against the wood ends, the outer wall of the plywood 15 is provided with anti-slip texture. It should be understood that the anti-slip texture can increase friction, thereby helping to prevent the wood ends from sliding. Specifically, the anti-slip texture can be a diamond pattern, and the interlaced texture can further enhance the anti-slip effect.

[0036] like Figure 1-4 As shown, in one embodiment, a rotating shaft 4 is fixedly connected to the top center of the carrier plate 24. The top of the rotating shaft 4 is rotatably connected to the bottom of the second limiting slider 27. A torsion spring disk 41 is fixedly fitted on the outer wall of the rotating shaft 4, and the torsion spring disk 41 is fixedly connected to the bottom of the second limiting slider 27.

[0037] It should be understood that the vibration generated during the sanding process can cause the sponge block 25 to rotate slightly along the axis of the rotating shaft 4, which is conducive to driving the sandpaper 26 to rotate axially. This is beneficial for sanding the columnar wood from multiple directions, which in turn helps to improve the sanding effect. Moreover, the existence of an axial movement trajectory helps to shake off the debris.

[0038] In order to prevent the rotating shaft 4 from rotating too much, fixed rods 42 are fixedly connected to both sides of the outer wall of the rotating shaft 4. Limiting rods 43 are fixed on both sides of the top of the carrier plate 24. It should be understood that the fixed rods 42 rotate with the rotating shaft 4 during reciprocating rotation. The fixed rods 42 can be limited by the limiting rods 43 during rotation, which helps to prevent the rotation amplitude from being too large and affecting the grinding.

[0039] like Figure 1 As shown, in one embodiment, it also includes a first driving assembly. The first driving assembly is installed in a first sliding cavity opened in the front side wall of the platform 1. The first driving assembly includes a dual-axis motor 11, which is fixed in the middle of the inner wall of the first sliding cavity. Both ends of the dual-axis motor 11 are fixedly connected to a first lead screw 12. The outer end of the first lead screw 12 is rotatably connected to the inner wall of the first sliding cavity. The outer wall of the first lead screw 12 is fitted with a matching first lead screw slider 13. The outer wall of the first lead screw slider 13 is fixedly connected to the movable frame 14.

[0040] It should be understood that the dual-axis motor 11 can drive the first lead screws 12 on both sides to rotate, thereby driving the first lead screw sliders 13 on both sides to move closer to each other, thereby driving the movable frames 14 on both sides to adjust the distance between them to adapt to the length of the wood.

[0041] like Figure 1-2 As shown in the embodiment, a second sliding cavity is provided on the back of the platform 1. A lead screw motor 3 is fixedly installed at one end of the inner cavity of the second sliding cavity. A second lead screw 31 is fixedly connected to the outer end of the drive shaft of the lead screw motor 3. The outer end of the second lead screw 31 is rotatably connected to the inner wall of the second sliding cavity. A matching second lead screw slider 32 is fitted on the outer wall of the second lead screw 31. The outer wall of the second lead screw slider 32 is fixedly connected to the movable rod 2.

[0042] It should be understood that the lead screw motor 3 can drive the second lead screw 31 to rotate, thereby driving the second lead screw slider 32 to move, and thus driving the movable rod 2 to move.

[0043] like Figure 1-3As shown in the figure, in one embodiment, a first limiting groove is provided on the upper side of the inner wall of the movable rod 2. A matching first limiting slider 21 is inserted into the inner cavity of the first limiting groove. A first electric push rod 22 is fixedly connected to the bottom of the first limiting slider 21. The tail end of the first electric push rod 22 is fixedly connected to the bottom of the inner cavity of the first limiting groove. The outer wall of the first limiting slider 21 is fixedly connected to the lifting plate 23.

[0044] It should be understood that the first electric actuator 22 drives the first limiting slider 21 to move up and down along the inner cavity of the first limiting groove, thereby driving the lifting plate 23 to move up and down, so that during sanding, the lifting plate 23 is driven down so that the sandpaper 26 adheres to the wood surface.

[0045] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
