Description

Technical Field

[0001] This utility model relates to the technical field of stone carving machines, specifically to a reducer for stone carving machines with anti-axial load function. Background Technology

[0002] A stone carving machine is a CNC device used for three-dimensional carving of stone. It can carve raw stone into various exquisite three-dimensional shapes and is widely used in architectural decoration, art sculpture, and garden landscape. The working principle of the stone carving machine is based on computer-aided design and computer-aided manufacturing technology. First, the designer uses CAD software to create a three-dimensional carving model, converting the design intent into a digital model that the computer can recognize. Then, CAM software processes the CAD model to generate a toolpath file, i.e., the carving program. The carving program contains the movement trajectory of the tool, cutting parameters, and other control instructions.

[0003] There are many types of stone, such as granite and marble, with significant differences in hardness, density, and internal structure. During the carving process, when the cutting tool comes into contact with areas of different hardness within the stone, uneven cutting forces are generated. The axial component of this force creates an axial load. For example, when the cutting tool encounters harder parts of the stone, such as quartz particles, the axial force increases instantaneously. Over time, this can cause loosening and affect the machine's usability. Therefore, there is an urgent need for a reducer with axial load protection for stone carving machines to overcome these defects. Utility Model Content

[0004] The purpose of this utility model is to provide a reducer with anti-axial load function for stone carving machines, which has the advantage of good anti-loosening effect, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a reducer with axial load protection function for a stone carving machine, comprising a carving machine body and an anti-load component. The anti-load component is disposed on the front of the carving machine body and includes a mounting plate, a reducer body, a clamping block, a crossbeam, a fixed clamping head, a bearing body, a fixed shaft, and a mounting groove.

[0006] Furthermore, mounting plates are fixedly installed on both sides of the crossbeam, and the reducer body is fixedly installed on both sides of the front of the crossbeam.

[0007] Furthermore, clamping blocks are provided on both sides of the back of the crossbeam, and uniformly distributed fixed clamping heads are fixedly installed on the back of the clamping blocks.

[0008] Furthermore, two mounting slots are provided inside the crossbeam, and two bearing bodies are fixedly installed in the inner cavity of each mounting slot.

[0009] Furthermore, a fixed shaft is fixedly installed inside the bearing body, and the output shaft of the reducer body passes through the inner cavity of the mounting groove and is fixedly connected to the front of the fixed shaft.

[0010] Furthermore, the back of the fixed shaft is fixedly connected to the front of the clamping block, and the side of the mounting plate that is relatively far away from the main body of the round engraving machine is fixedly connected to the inner cavity of the main body of the engraving machine by bolts.

[0011] In summary, due to the adoption of the above-mentioned technologies, the beneficial effects of this utility model are:

[0012] This invention features a circular carving machine body primarily used for grinding stone. By incorporating anti-load components in the reducer body and fixed shaft—areas susceptible to axial loads—bearing bodies are installed. These bearing bodies can simultaneously withstand radial and axial loads. Furthermore, by adjusting the bearing body's clearance and preload, its axial load-bearing capacity and rigidity can be improved, resulting in excellent anti-loosening performance. This solves the problem that when the cutting tool encounters hard parts of the stone, such as quartz particles, the axial force increases instantaneously, leading to loosening over time and affecting usability.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] This utility model provides, for example Figure 1-3 As shown, a reducer with anti-axial load function for a stone carving machine includes a carving machine body 1 and an anti-load component 2. The anti-load component 2 is disposed on the front of the carving machine body 1. The anti-load component 2 includes a mounting plate 21, a reducer body 22, a clamping block 23, a crossbeam 24, a fixed clamping head 25, a bearing body 26, a fixed shaft 27, and a mounting groove 28.

[0019] More specifically, the main body 1 of the round carving machine is set to grind the stone. The anti-load component 2 is set to install the bearing body 26 in the parts of the reducer body 22 and the fixed shaft 27 that are easily affected by axial load. The bearing body 26 can bear both radial and axial loads at the same time. By adjusting the clearance and preload of the bearing body 26, its load-bearing capacity and rigidity for axial load can be improved, and it has the advantage of good anti-loosening effect.

[0020] In some embodiments, mounting plates 21 are fixedly installed on both sides of the crossbeam 24, and the reducer body 22 is fixedly installed on both sides of the front of the crossbeam 24. More specifically, the crossbeam 24 is fixed by setting the mounting plates 21, and the reducer body 22 is installed by setting the crossbeam 24.

[0021] In some embodiments, clamping blocks 23 are provided on both sides of the back of the crossbeam 24, and uniformly distributed fixing clamping heads 25 are fixedly installed on the back of the clamping blocks 23. More specifically, the fixing clamping heads 25 are installed by setting the clamping blocks 23, and one side of the stone is fixed.

[0022] In some embodiments, the crossbeam 24 has two mounting slots 28 inside, and two bearing bodies 26 are fixedly installed in the inner cavity of each mounting slot 28. More specifically, the bearing bodies 26 are installed by setting the mounting slots 28.

[0023] In some embodiments, a fixed shaft 27 is fixedly installed inside the bearing body 26, and the output shaft of the reducer body 22 passes through the inner cavity of the mounting groove 28 and is fixedly connected to the front of the fixed shaft 27. More specifically, by selecting an angular contact ball bearing for the bearing body 26 and by reasonably configuring the bearing installation method and preload, the axial force can be effectively resisted, ensuring the rotational accuracy and stability of the fixed shaft 27.

[0024] In some embodiments, the back of the fixed shaft 27 is fixedly connected to the front of the clamping block 23, and the side of the mounting plate 21 that is relatively far away from the main body 1 of the round engraving machine is fixedly connected to the inner cavity of the engraving machine body 1 by bolts. More specifically, the clamping block 23 is driven by setting the fixed shaft 27.

[0025] Working principle:

[0026] In use: The main body 1 of the circular carving machine is used to grind the stone. An anti-load assembly 2 is installed at the reducer body 22 and the fixed shaft 27, where they are susceptible to axial loads. Bearing bodies 26 are installed at these locations. The bearing bodies 26 can simultaneously withstand radial and axial loads. By adjusting the clearance and preload of the bearing bodies 26, their axial load-bearing capacity and rigidity can be improved. A mounting plate 21 is used to fix the crossbeam 24, which in turn mounts the reducer body 22. A clamping block 23 is used to fix the clamping head 2. 5. Install the bearing and fix one side of the stone. Install the bearing body 26 through the installation groove 28. The bearing body 26 is selected as an angular contact ball bearing. By reasonably configuring the bearing installation method and preload, it can effectively withstand axial force and ensure the rotation accuracy and stability of the fixed shaft 27. The fixed shaft 27 drives the clamping block 23, which has the advantage of good anti-loosening effect. It solves the problem that when the tool encounters the hard parts such as quartz particles in the stone, the axial force will increase instantly and loosen over time, affecting the use.
