Abstract
Description
Technical Field
[0001] This utility model relates to the field of wood carving polishing technology, specifically a polishing device for wood carving processing. Background Technology
[0002] Wood carving, as an important part of traditional handicrafts and modern decorative arts, is widely used in furniture manufacturing, craft production, and cultural heritage preservation. Polishing, a crucial step in wood carving, directly affects the texture, luster, and artistic expression of the finished product. However, traditional wood carving polishing techniques and equipment face many problems that urgently need to be addressed.
[0003] In the traditional hand polishing process, craftsmen mostly use tools such as sandpaper and polishing cloth to polish by hand, which is extremely inefficient. Especially for wood carvings with complex shapes and rich details, a single polishing can take several hours or even days, which is difficult to meet the needs of large-scale production and restricts the commercial development of the wood carving industry.
[0004] With the popularization of mechanized production, some enterprises have introduced automated polishing equipment, but existing equipment still has limitations. Currently, mechanical polishing equipment generally uses clamping to position the wood carving on the worktable. However, this method prevents the clamped area from being reached by the polishing tool, creating polishing dead zones. Especially for wood carvings with complex shapes and delicate carving textures, the choice of clamping position often presents a dilemma: if the clamp is placed in a conspicuous location for stable clamping, a large surface area cannot be polished; if the clamping position is adjusted to avoid important carving areas, the wood carving is prone to shaking during polishing, affecting polishing accuracy or even causing damage to the wood carving. Utility Model Content
[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a polishing device for wood carving to solve the shortcomings of the prior art.
[0006] The purpose of this utility model is achieved through the following technical solution: a polishing device for wood carving, including a polishing platform and a polishing mechanism, wherein a rotating disk is rotatably provided on the top surface of the polishing platform, the rotation axis of the rotating disk is vertically arranged, a threaded column is coaxially fixed on the top of the rotating disk, and a threaded hole is provided at the bottom of the wood carving, wherein the threaded column is threaded into the threaded hole.
[0007] The polishing mechanism includes a base, a sliding seat, and a lifting beam. The sliding seat is slidably mounted on the base and has the freedom to move closer to or away from the rotating disk. The lifting beam is mounted on the sliding seat and has the freedom to move along the axial direction of the rotating disk. A polishing assembly is provided at the bottom of the lifting beam. The polishing assembly includes a rotatably mounted polishing shaft, and several bristles are densely fixed to the side wall of the polishing shaft.
[0008] Furthermore, a motor is installed inside the polishing platform, and a main shaft is coaxially fixed to the bottom of the rotating disk. The main shaft is rotatably connected to the polishing platform through bearings, and the output shaft of the motor is connected to the main shaft for transmission.
[0009] Furthermore, a limiting groove is eccentrically formed at the bottom of the rotating disk, and a limiting rod is vertically installed on the polishing platform. The limiting rod has the degree of freedom to move along the axial direction of the rotating disk, and the top of the limiting rod is adapted to the limiting groove to restrict the rotational degree of freedom of the rotating disk.
[0010] Furthermore, the top of the polishing platform is provided with an installation groove, an electromagnet is provided in the installation groove, the bottom of the limiting rod is slidably adapted in the installation groove and connected to a permanent magnet, a spring is provided in the installation groove, and the two ends of the spring are respectively connected to the limiting rod and the polishing platform.
[0011] Furthermore, a linear drive module is mounted on the top of the base, and the sliding seat is mounted on the sliding seat of the linear drive module.
[0012] Furthermore, a cylinder is vertically mounted on the sliding seat, and the telescopic shaft of the cylinder is connected to the lifting beam.
[0013] Furthermore, the polishing assembly also includes a U-shaped seat with the U-shaped opening facing downwards. The polishing shaft is rotatably installed inside the U-shaped opening of the U-shaped seat. A motor is installed at one end of the U-shaped seat, and the output shaft of the motor is connected to the polishing shaft.
[0014] The beneficial effects of this utility model are:
[0015] 1. By connecting the threaded post with the threaded hole at the bottom of the wood carving, the center of the wood carving is fixed. Compared with the traditional side clamping method, it avoids the clamp from obstructing the surface of the wood carving. With the help of the rotating disk to drive the wood carving to rotate, the polishing component can polish the surface of the wood carving 360 degrees without dead angles.
[0016] 2. Driven by a motor, the rotating disc rotates continuously. Combined with the freedom of the sliding seat in the polishing mechanism to move closer to or further away from the disc, and the lifting beam to move axially along the disc, the polishing components can quickly cover different areas of the wood carving. Unlike traditional equipment, there's no need to frequently adjust the carving's position or change tooling fixtures. Furthermore, multiple sets of brushes simultaneously act on the wood carving surface, achieving large-area, efficient polishing and significantly shortening the polishing time for a single carving, meeting the needs of large-scale production.
[0017] 3. The use of threaded connections to fix the wood carving not only avoids the problems of clamping marks and pressure damage compared to traditional rigid clamping, but also provides a stable fixing effect, preventing the wood carving from shifting due to vibration or uneven force during the polishing process.

Detailed Implementation
[0021] Example 1
[0022] like Figure 1 and Figure 2 As shown, a polishing device for wood carving includes a polishing platform 1 and a polishing mechanism. A rotating disk 2 is rotatably mounted on the top surface of the polishing platform 1, with the rotation axis of the rotating disk 2 vertically positioned. A threaded post 3 is coaxially fixed to the top of the rotating disk 2. A threaded hole is provided at the bottom of the wood carving, and the threaded post 3 is threaded into the threaded hole. The polishing mechanism includes a base 4, a sliding seat 5, and a lifting beam 6. The sliding seat 5 is slidably mounted on the base 4 and has the freedom to move closer to or away from the rotating disk 2. The lifting beam 6 is mounted on the sliding seat 5 and has the freedom to move along the axial direction of the rotating disk 2. A polishing assembly is provided at the bottom of the lifting beam 6. The polishing assembly includes a rotatably mounted polishing shaft 7, and several brush bristles 8 are densely fixed to the side wall of the polishing shaft 7. Before polishing, the bottom of the wood carving is drilled using a drilling machine. A threaded hole, located at the bottom of the wood carving, does not affect its appearance and facilitates subsequent polishing. The wood carving to be processed is threaded onto the threaded post 3 of the rotating disk 2, securing the carving while exposing its entire surface. The movement of the lifting beam 6 and sliding seat 5 causes the bristles 8 of the polishing shaft 7 to contact the wood carving. The polishing shaft 7 drives the bristles 8 to rotate, polishing the surface of the wood carving. Simultaneously, the rotating disk 2 rotates the wood carving, achieving 360° polishing. The lifting beam 6 moves the bristles 8 along the height of the wood carving, completing the overall polishing. The bristles are elastic, adapting to the shape of the wood carving surface and penetrating the grain, achieving comprehensive polishing and significantly improving the polishing effect. Preferably, the bristles 8 are made of nylon, which has high elasticity, wear resistance, and corrosion resistance.
[0023] Example 2
[0024] Based on Embodiment 1, a linear drive module 16 is installed on the top of the base 4, and a sliding seat 5 is installed on the sliding seat of the linear drive module 16. A cylinder 17 is vertically installed on the sliding seat 5, and the telescopic shaft of the cylinder 17 is connected to the lifting beam 6. The polishing assembly also includes a U-shaped seat 18, with the U-shaped opening of the U-shaped seat 18 facing downwards. The polishing shaft 7 is rotatably installed in the U-shaped opening of the U-shaped seat 18. A motor 19 is installed at one end of the U-shaped seat 18, and the output shaft of the motor 19 is connected to the polishing shaft 7. The linear drive module 16 drives the sliding seat 5 to move closer to or away from the rotating disk 2, so that the brush bristles 8 contact the wood carving for polishing, or move away from the wood carving for loading and unloading. The telescopic movement of the cylinder 17 drives the lifting beam 6 to move up and down, so that the brush bristles 8 can move along the height direction of the wood carving to complete the overall polishing. The motor 19 drives the polishing shaft 7 to rotate, so that the brush bristles 8 rotate to contact the wood carving to complete the polishing operation.
[0025] Example 3
[0026] Based on Embodiment 2, a motor is installed inside the polishing platform 1, and a main shaft 9 is coaxially fixed at the bottom of the rotating disk 2. The main shaft 9 is rotatably connected to the polishing platform 1 through bearings. The output shaft of the motor is connected to the main shaft 9. The motor drives the rotating disk 2 to rotate, and the rotating disk 2 drives the wood carving to rotate, so as to achieve 360° polishing of the wood carving without dead angles.
[0027] Example 4
[0028] Based on Example 3, such as Figure 1 and Figure 2As shown, a limiting groove 10 is eccentrically formed at the bottom of the rotating disk 2. A limiting rod 11 is vertically mounted on the polishing platform 1. The limiting rod 11 has the freedom to move along the axial direction of the rotating disk 2. The top of the limiting rod 11 is fitted into the limiting groove 10 to restrict the rotational freedom of the rotating disk 2. A mounting groove 12 is formed at the top of the polishing platform 1. An electromagnet 13 is installed in the mounting groove 12. The bottom of the limiting rod 11 is slidably fitted into the mounting groove 12 and connected to a permanent magnet 14. A spring 15 is installed in the mounting groove 12. The two ends of the spring 15 are respectively connected to the limiting rod 11 and the polishing platform 1. When the spring 15 is in its normal state, the limiting rod 11 is separated from the limiting groove 10. When disassembling or installing the wood carving, it is necessary to rotate the wood carving for installation and removal. Because the rotating disk 2 has the rotational freedom, it will... The installation and removal of the wood carving are affected. Therefore, when the wood carving needs to be installed or removed, the electromagnet 13 is energized. The energized electromagnet 13 generates a magnetic pole with the same magnetism as the permanent magnet 14, causing the electromagnet 13 to repel the permanent magnet 14, causing the limiting rod 11 to move upward. The top of the limiting rod 11 abuts against the bottom of the rotating disk 2. When the wood carving is installed or removed, the rotating disk 2 will rotate. When the limiting groove 10 corresponds to the limiting rod 11, the limiting rod 11 is inserted into the limiting groove 10 under the repulsive force, thereby restricting the rotational freedom of the rotating disk 2, so that the wood carving can be installed and removed smoothly. After the wood carving is loaded, the electromagnet 13 is de-energized, and the limiting rod 11 is disengaged from the limiting groove 10 under the reaction force of the spring 15, unlocking the rotational freedom of the rotating disk 2, and the wood carving polishing operation can then be carried out.
