Description

Technical Field

[0001] This utility model relates to the field of solid wood furniture processing technology, and in particular to a carving device for solid wood furniture. Background Technology

[0002] Solid wood furniture carving refers to the process of carving various patterns, designs, or three-dimensional shapes onto solid wood materials using manual or mechanical means. This craft plays a vital role in solid wood furniture production, not only giving the furniture a beautiful appearance but also reflecting its cultural connotations and artistic value. Mechanical carving, performed using CNC machines, can accurately replicate design patterns and is suitable for large-scale production and highly complex designs.

[0003] In existing technologies, traditional solid wood furniture carving usually requires carving one side of the wood first, then flipping it over to carve the other side. This operation requires stopping the machine, resulting in reduced carving efficiency. Furthermore, the dust generated by the carving drill during the carving process cannot be effectively controlled, posing a potential hazard. Therefore, we propose a carving device for solid wood furniture to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a carving device for solid wood furniture.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A carving device for solid wood furniture includes a base frame. An XYZ high-precision moving platform is fixedly connected to the top of the base frame. Two through holes are formed on the inner wall of the base frame, and a round shaft is rotatably connected to the inner wall of each through hole. A bracket is fixedly connected to the outer wall of the base frame, and a servo motor is fixedly connected to the top of the bracket. The outer wall of the servo motor's output shaft is fixedly connected to one end of one of the round shafts. A U-shaped frame is fixedly connected to one end of both round shafts. Multiple cylinders are fixedly connected to the outer wall of the U-shaped frame, and foot pads are fixedly connected to the outer wall of the output ends of the multiple cylinders. Two round frames are fixedly connected to the top of the base frame, and DC motors are fixedly connected inside each of the two round frames. Vertical rods are fixedly connected to the bottom of the output shafts of the two DC motors, and support plates are fixedly connected to the bottom of the two vertical rods. An assembly plate is fixedly connected to the bottom of the movable end of the XYZ high-precision moving platform, and a dust collection mechanism is provided on the outer wall of the assembly plate.

[0007] Preferably, the dust collection mechanism includes a circular tube, and the outer wall of the assembly plate has an installation hole. The inner wall of the installation hole is slidably connected to the outer wall of the circular tube. A silicone circular cover is fixedly connected to the bottom of the circular tube. An expansion sleeve and an inner conical sleeve are fitted on the outer wall of the circular tube. The top of the expansion sleeve is fixedly connected to the bottom of the assembly plate. The inner wall of the inner conical sleeve is pressed against the outer wall of the expansion sleeve. The dust generated during engraving is sucked away by the dust collection mechanism.

[0008] Preferably, the outer wall of the U-shaped frame is provided with multiple sliding holes, and the inner walls of the multiple sliding holes are slidably connected to the outer walls of the output ends of multiple cylinders respectively. The synchronous operation of the multiple cylinders is simultaneously controlled by an existing synchronous controller and a solenoid valve. The solenoid valve is adjusted in real time by controlling the on and off time of the solenoid valve and by feedback from existing sensors (such as displacement sensors and pressure sensors).

[0009] Preferably, the outer wall of the bottom frame has two rectangular slots, the outer walls of multiple foot pads are in contact with the same piece of wood, and the foot pads are made of silicone material.

[0010] Preferably, the bottom of both circular frames is provided with through holes, and the inner walls of the two through holes are rotatably connected to the outer walls of the output shafts of the two DC motors, thereby protecting the DC motors by setting the circular frames.

[0011] Preferably, an engraving head is fixedly connected to the bottom of the assembly plate, and an engraving drill bit is rotatably connected to the bottom of the engraving head, which is driven by an existing motor.

[0012] Preferably, a metal corrugated pipe is fixedly connected to the top of the circular tube, a dust removal fan is fixedly connected to one end of the metal corrugated pipe, and a filter bag is fixedly installed at the input end of the dust removal fan.

[0013] Compared with the prior art, the advantages of this utility model are:

[0014] This solution, by setting up a circular shaft, a loop frame, a cylinder, foot pads, a DC motor, a vertical rod, and a support plate, flips the wood over without affecting the carving process, making it easier to carve both sides of the board. By setting up a circular tube, a metal corrugated tube, a silicone round cover, an expansion sleeve, and an inner conical sleeve, negative pressure is used to suck away the dust generated during carving. The height of the circular tube can be adjusted by rotating the inner conical sleeve to meet the dust removal needs of different sized drill bits during carving, achieving the benefit of close-range dust suction without affecting the carving process.

[0023] Depend on Figures 1-5As shown, a carving device for solid wood furniture is disclosed, comprising a base frame 1, with an XYZ high-precision moving platform 2 fixedly connected to the top of the base frame 1. The XYZ high-precision moving platform 2, also known as a three-coordinate high-precision moving platform, is a platform that achieves precise movement in the X, Y, and Z directions. The XYZ platform mainly includes an X-axis moving part, a Y-axis moving part, and a Z-axis moving part. The couplings of each axis can be used to connect to existing motors to achieve automatic adjustment. Two through holes are opened on the inner wall of the base frame 1, and a round shaft 3 is rotatably connected to the inner wall of each through hole. A bracket is fixedly connected to the outer wall of the base frame 1, and a servo motor is fixedly connected to the top of the bracket. The outer wall of the output shaft of the servo motor is fixedly connected to one end of one of the round shafts 3. The operation of the servo motor drives the round shaft 3 connected to it to rotate, and the rotation of the round shaft 3 drives the rotating frame 4 to rotate, and the rotation of the rotating frame 4 drives the wood to flip over.

[0024] Two circular shafts 3 are fixedly connected to the same U-shaped frame 4 at one end. Multiple cylinders 5 are fixedly connected to the outer wall of the U-shaped frame 4. Multiple sliding holes are opened on the outer wall of the U-shaped frame 4. The inner walls of the multiple sliding holes are slidably connected to the outer walls of the output ends of the multiple cylinders 5. Foot pads 6 are fixedly connected to the outer walls of the output ends of the multiple cylinders 5. The operation of the multiple cylinders 5 drives the multiple foot pads 6 to move relative to each other. The multiple foot pads 6 press against the outer wall of the wood, fixing the wood board in the U-shaped frame 4. Two rectangular slots are opened on the outer wall of the bottom frame 1. The outer walls of the multiple foot pads 6 contact the same wood.

[0025] Two circular frames 7 are fixedly connected to the top of the bottom frame 1. A DC motor 8 is fixedly connected inside the two circular frames 7. The two DC motors 8 can rotate in sequence to drive the two vertical rods 9 and the support plate 10 to rotate. The bottom of the two circular frames 7 is provided with through holes. The inner walls of the two through holes are rotatably connected to the outer walls of the output shafts of the two DC motors 8 respectively.

[0026] The bottom of the output shafts of the two DC motors 8 are fixedly connected to vertical rods 9, and the bottom of the two vertical rods 9 are fixedly connected to support plates 10. The bottom of the wood is supported by the two support plates 10. The bottom of the movable end of the XYZ high-precision moving platform 2 is fixedly connected to an assembly plate 11.

[0027] The outer wall of the assembly plate 11 is provided with a dust collection mechanism, which includes a round tube 12. A metal corrugated pipe 13 is fixedly connected to the top of the round tube 12. A dust removal fan is fixedly connected to one end of the metal corrugated pipe 13. The operation of the dust removal fan generates negative pressure inside the metal corrugated pipe 13. An installation hole is opened on the outer wall of the assembly plate 11, and the inner wall of the installation hole is slidably connected to the outer wall of the round tube 12.

[0028] A silicone dome 14 is fixedly connected to the bottom of the cylindrical tube 12. The silicone dome 14 sucks away the dust generated during engraving. An expansion sleeve 15 and an inner conical sleeve 16 are fitted on the outer wall of the cylindrical tube 12. The top of the expansion sleeve 15 is fixedly connected to the bottom of the assembly plate 11. The inner wall of the inner conical sleeve 16 is pressed against the outer wall of the expansion sleeve 15. Multiple conical pieces are fixedly connected to the outer wall of the expansion sleeve 15 and are arranged in a ring. After the inner conical sleeve 16 is pressed against the outer wall of the expansion sleeve 15, the multiple conical pieces move inward and are pressed against the outer wall of the cylindrical tube 12 to fix its position. An engraving head 17 is fixedly connected to the bottom of the assembly plate 11.

[0029] Working Principle: During use, the wood is placed on top of the two support plates 10 and inside the U-shaped frame 4. Multiple cylinders 5 operate, causing multiple foot pads 6 to move relative to each other. The foot pads 6 press against the outer wall of the wood, fixing the wood within the U-shaped frame 4. The bottom of the wood is supported by the two support plates 10. The XYZ high-precision moving platform 2 drives the carving head 17 to move at multiple angles. The high-speed rotating carving drill at the bottom of the carving head 17 carves the wood. Simultaneously, the dust removal fan operates, creating negative pressure inside the metal bellows 13. This negative pressure draws away dust generated during carving through the silicone dome 14. The dust is filtered through a filter bag installed at the input end of the dust removal fan. The height of the silicone dome 14 can be adjusted by rotating its inner cone. Adjust the sleeve 16, rotate the inner conical sleeve 16 so that its inner conical surface no longer presses against the outer wall of the expansion sleeve 15, release the position fixation of the round tube 12, and allow the round tube 12 to move up and down. After the top side of the wood is finished, the two DC motors 8 rotate the two vertical rods 9 in sequence. The rotation of the two vertical rods 9 drives the two support plates 10 to rotate outward. The two support plates 10 rotate and slide outward through the two rectangular slots, no longer located at the bottom of the wood. The servo motor runs and drives the round shaft 3 connected to it to rotate. The rotation of the round shaft 3 drives the return frame 4 to rotate. The rotation of the return frame 4 drives the wood to flip over. After the wood is flipped over, the two DC motors 8 run to reset, so that the two support plates 10 are located at the bottom of the wood board again to support the wood.
