Description

Technical Field

[0001] This utility model relates to the technical field of precision machine tools, specifically to vibration-resistant precision machine tools. Background Technology

[0002] Machine tools are important mechanical processing equipment. In modern mechanical manufacturing, there are many methods for processing mechanical parts: in addition to cutting, there are casting, forging, welding, stamping, extrusion, etc. However, for parts with high precision requirements and fine surface roughness requirements, they generally need to be finally processed by cutting on machine tools. Machine tools play a significant role in the modernization of the national economy. However, vibration is extremely harmful in machine tool processing, especially when using diamond tools for ultra-precision cutting on ultra-precision machine tools. The machine tool must operate extremely smoothly with minimal vibration; otherwise, it is difficult to guarantee high machining accuracy and ultra-smooth surface quality.

[0003] Chinese patent CN216463333U discloses a vibration prevention device for precision machining tools, including a support column. A mounting plate is fixedly connected to the top of the support column. A control panel is fixedly connected to the middle right side of the mounting plate. A machine tool body is fixedly connected to a groove at the top of the mounting plate. Mounting slots are provided inside the mounting plate on both the left and right sides of the machine tool body. Electric cylinders are fixedly connected to the inner wall of the mounting slots on the side away from the machine tool body. A fixing plate is fixedly connected to the opposite end of each electric cylinder.

[0004] In the above scheme, multiple vibration reduction measures are used in combination to improve the vibration reduction effect on the machine tool, thereby enhancing the stability of the machine tool processing. However, it has the following disadvantages: When this device reduces vibration on the machine tool, it uses multiple sets of flexible materials such as springs in combination. This causes the springs to be compressed and stretched during vibration reduction, converting vibration energy into elastic potential energy. This can easily cause the machine tool to move horizontally, thus affecting the processing quality of the product. Utility Model Content

[0005] The purpose of this invention is to provide a vibration-damping precision machine tool to solve the problem that when multiple sets of flexible materials such as springs are used in conjunction to reduce vibration in a machine tool, the springs are compressed and stretched, converting vibration energy into elastic potential energy, which easily causes the machine tool to move horizontally.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a vibration-damping precision machine tool, comprising a machine tool body, the machine tool body being disposed above a support base, the top surface of the support base having a plurality of sliding grooves, two of the plurality of sliding grooves forming a group, a sliding column being fixed to the inner wall of the sliding groove, a spring being wound around the outer wall of the sliding column, a sliding block being slidably connected to the outer wall of the sliding column, one end of the spring being fixed to one side of the sliding block, the other end of the spring being fixed to one side of the inner wall of the sliding groove, a sliding hole being provided on one side of the sliding block, the sliding column being slidably connected to the sliding hole, a connecting plate being rotatably disposed on the top surface of the sliding block, the top surface of the connecting plate being movably hinged to the bottom surface of the machine tool body, two mounting grooves being provided on the top surface of the support base, a damper being fixed to the inner wall of the mounting groove, the telescopic end of the damper being fixed to the bottom surface of the machine tool body, the sliding block being able to slide within a certain range, and in conjunction with the spring and the damper, the levelness of the machine tool body can be finely adjusted.

[0007] Preferably, two support blocks are fixed to the bottom surface of the machine tool body, and damping rubber is fixed to the bottom surface of the support blocks. The damping rubber can adaptively adjust its shape to maintain good contact between the bottom surface of the machine tool body and the support base, thereby increasing the overall stability of the machine tool body and reducing shaking and vibration caused by uneven mounting surfaces.

[0008] Preferably, a protective cover is slidably provided on the outer wall of the machine tool body. The outer wall of the protective cover has two limiting holes. A limiting block is fixed on the outer wall of the machine tool body. The limiting block is slidably connected to the limiting holes. The sliding protective cover can be slid to a suitable position according to the needs of the operator, so as to maintain various parts inside the machine tool body and reduce maintenance time.

[0009] Preferably, the outer wall of the protective cover is provided with a fixing groove, and a transparent panel is fixed to the inner wall of the fixing groove. The protective cover can prevent workers from accidentally touching the internal operating parts of the machine tool body, thereby improving the safety of the machine tool body.

[0010] Preferably, the top surface of the machine tool body is provided with a plurality of ventilation holes, and a filter screen is fixed on the inner wall of the ventilation holes. The filter screen can effectively block dust and impurities, ensure the cleanliness of the inside of the machine tool body, help maintain a good working environment inside the machine tool body, thereby extending the service life of the machine tool body components. The sound insulation pad can reduce the noise intensity of the machine tool body during operation, thereby providing a more comfortable working environment for the staff.

[0011] Preferably, sound insulation pads are fixed on both the left and right sides of the machine tool body.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. By combining dampers and springs, a vibration reduction space is provided for the machine tool body when it is subjected to vibration, allowing the machine tool body to move adaptively during vibration. This effectively isolates and reduces the impact of vibration on the machine tool body, thereby improving the machining accuracy of the machine tool. The damping rubber effectively isolates vibrations transmitted from the support base, preventing external vibrations from interfering with the normal operation of the machine tool body and ensuring that the machine tool body is in a relatively stable working state.

[0014] Second, the combination of the limiting holes and limiting blocks allows operators to easily open and close the protective cover, facilitating quick tool changes and improving work efficiency. The transparent panel allows operators to directly observe the machining process inside the machine tool without opening the protective cover, preventing external dust and impurities from entering and ensuring continuous machining. The sound-insulating pad reduces the transmission of internal noise and effectively prevents external noise from entering the machine tool, avoiding unnecessary vibrations caused by noise and indirectly improving machining accuracy.

[0020] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] like Figures 1-4As shown, a vibration-damping precision machine tool includes a machine tool body 1, which is positioned above a support base 2. The top surface of the support base 2 has several sliding grooves 3, with two sliding grooves 3 forming a group. A sliding column 4 is fixed to the inner wall of each sliding groove 3, and a spring 5 is wound around the outer wall of the sliding column 4. A sliding block 6 is slidably connected to the outer wall of the sliding column 4. One end of the spring 5 is fixed to one side of the sliding block 6, and the other end of the spring 5 is fixed to one side of the inner wall of the sliding groove 3. A sliding hole 7 is provided on one side of the sliding block 6, and the sliding column 4 is slidably connected to the sliding hole 7. A connecting plate 8 is rotatably mounted on the top surface of the sliding block 6, and the top surface of the connecting plate 8 is hinged to the bottom surface of the machine tool body 1. Two mounting grooves 9 are provided on the top surface of the support base 2, and a damper 10 is fixed to the inner wall of each mounting groove 9. The telescopic end of the damper 10 is fixed to the bottom surface of the machine tool body 1. Two support blocks 11 are fixed to the bottom surface of the machine tool body 1, and damping rubber 12 is fixed to the bottom surface of each support block 11.

[0022] In use, the damper 10, in conjunction with the spring 5, provides vibration reduction space for the machine tool body 1 when it is subjected to vibration, allowing the machine tool body 1 to move adaptively during vibration. This effectively isolates and reduces the impact of vibration on the machine tool body 1 under the action of the damper 10, thereby improving the machining accuracy of the machine tool body 1. Simultaneously, the sliding block 6 can slide within a certain range, and in conjunction with the spring 5 and damper 10, can fine-tune the levelness of the machine tool body 1. The damping rubber 12 effectively isolates vibration transmitted from the support base 2, preventing external vibrations from interfering with the normal operation of the machine tool body 1 and ensuring that the machine tool body 1 is in a relatively stable working state. Furthermore, the damping rubber 12 can adaptively adjust its shape to maintain good contact between the bottom surface of the machine tool body 1 and the support base 2, thereby increasing the overall stability of the machine tool body 1 and reducing wobbling and vibration caused by uneven mounting surfaces.

[0023] like Figure 1 , Figure 2 and Figure 4 As shown, a protective cover 13 is slidably provided on the outer wall of the machine tool body 1. Two limiting holes 14 are opened on the outer wall of the protective cover 13. A limiting block 15 is fixed on the outer wall of the machine tool body 1. The limiting block 15 is slidably connected to the limiting hole 14. A fixing groove 16 is opened on the outer wall of the protective cover 13. A transparent panel 17 is fixed on the inner wall of the fixing groove 16.

[0024] During use, the cooperation of the limiting hole 14 and the limiting block 15 allows operators to easily open and close the protective cover 13, facilitating quick tool changes and improving work efficiency. Simultaneously, the sliding protective cover 13 can be moved to a suitable position as needed, allowing for maintenance of various internal parts of the machine tool body 1 and reducing maintenance time. The transparent panel 17 allows operators to directly observe the machining process inside the machine tool body 1 without opening the protective cover 13, thus preventing the entry of external dust and impurities and ensuring the continuity of the machining process. Furthermore, the protective cover 13 prevents operators from accidentally touching operating components inside the machine tool body 1, thereby improving the safety of the machine tool body 1.

[0025] like Figure 1 , Figure 2 and Figure 4 As shown, the top surface of the machine tool body 1 has several ventilation holes 18, the inner wall of the ventilation holes 18 is fixed with a filter screen 19, and the left and right sides of the machine tool body 1 are fixed with sound insulation pads 20.

[0026] During use, the filter screen 19 effectively blocks dust and impurities, ensuring the cleanliness of the machine tool body 1 and helping to maintain a good working environment inside the machine tool body 1, thereby extending the service life of the machine tool body 1 components. The sound insulation pad 20 reduces the transmission of internal noise from the machine tool body 1 to the outside and effectively prevents external noise from entering the machine tool body 1, avoiding unnecessary vibration caused by noise, thereby indirectly improving machining accuracy. At the same time, the sound insulation pad 20 can reduce the noise intensity of the machine tool body 1 during operation, thus providing a more comfortable working environment for the operators.
