Description

Technical Field

[0001] This application relates to the field of horizontal milling machine technology, and more particularly to a sound insulation and noise reduction device for the spindle box of a horizontal milling machine. Background Technology

[0002] The spindle box is an important component of a machine tool. It is used to house the machine tool's working spindle, its transmission parts, and corresponding auxiliary mechanisms. The spindle box is a complex transmission component, including the spindle assembly, reversing mechanism, transmission mechanism, braking device, operating mechanism, and lubrication device. Its main function is to support the spindle and enable it to rotate, realizing functions such as spindle starting, braking, speed change, and reversing.

[0003] Milling machines generate a lot of noise during operation, especially mid-to-high frequency noise. This not only affects the surrounding working environment, but may also damage the hearing and health of workers who are exposed to high noise for a long time. Moreover, the vibration of the milling machine during operation may cause instability of the entire equipment, increasing the risk of accidents, and this vibration itself also generates additional noise.

[0004] Therefore, considering that the milling machine generates a lot of noise during operation, and that the vibration of the milling machine during operation may cause instability of the entire equipment, increasing the risk of accidents, and that this vibration itself also generates additional noise, a sound insulation and noise reduction device for the spindle box of the horizontal milling machine can be designed. This device uses mineral fiber boards to convert sound energy into heat energy to absorb sound, and uses sound-absorbing holes to absorb mid-to-high frequency noise, effectively reducing the noise generated during the operation of the milling machine. Through the combined action of the vibration damping components, the stability and impact resistance of the equipment are enhanced, and the transmission of noise caused by vibration is reduced. Summary of the Invention

[0005] In order to overcome the disadvantages of milling machines generating a lot of noise during operation, and the vibration of milling machines during operation may cause instability of the entire equipment, increasing the risk of accidents, and the vibration itself also generating additional noise, this application provides a sound insulation and noise reduction device for the spindle box of a horizontal milling machine.

[0006] The technical solution is as follows: A sound insulation and noise reduction device for a horizontal milling machine spindle box includes a mounting base, a mounting frame, a supporting sliding frame, a mineral fiber board, sound-absorbing holes, a fixing plate, and a pull plate. The mounting frame for placing the milling machine spindle box is installed at the center of the upper end of the mounting base. The supporting sliding frame is installed around the front end of the mounting frame. The supporting sliding frame is slidably connected to a mineral fiber board for absorbing sound by converting sound energy into heat energy. Multiple sets of sound-absorbing holes are linearly opened on the surface of the mineral fiber board to absorb mid-to-high frequency noise using tiny pores. A fixing plate is fixedly connected to the upper front end of the mineral fiber board. A pull plate for stretching the mineral fiber board outward and connecting it with other devices is fixedly connected to the center of the upper surface of the fixing plate.

[0007] Furthermore, a support block is fixedly connected to the center of the lower surface of the mounting frame, and a movable plate is fixedly connected to the center of the lower surface of the support block.

[0008] Furthermore, anti-collision plates are fixedly connected to both sides of the movable plate, and shock-absorbing pads corresponding to the anti-collision plates are provided on the upper inner side of the mounting base.

[0009] Furthermore, a shock-absorbing plate is fixedly connected to the center of the mounting base, and multiple sets of mounting grooves are opened from left to right on the center of the upper surface of the shock-absorbing plate.

[0010] Furthermore, a sliding column is installed in the center of the mounting slot, and a sliding cavity is opened in the center of the sliding column.

[0011] Furthermore, a damping spring is installed in the center of the sliding cavity, and a spring damper is installed inside the damping spring.

[0012] Furthermore, a support column is installed at the upper end of the shock-absorbing spring and is fixedly connected to the movable plate. The support column is slidably connected to the sliding column.

[0013] The beneficial effects are that the mineral fiber board can convert sound energy into heat energy, effectively absorbing noise. The multiple sets of sound-absorbing holes on the surface further enhance the absorption capacity for mid-to-high frequency noise. The design of the fixed plate and pull plate makes it easy to stretch the mineral fiber board outward, facilitating cleaning, replacement, or other maintenance operations. The internal sliding connection design of the support sliding frame allows the position of the mineral fiber board to be adjusted as needed to achieve the best sound absorption effect. The mounting base and mounting frame provide a stable support structure, ensuring that the entire device is firm and reliable, reducing additional noise caused by vibration. Through efficient sound absorption and a stable structural design, the noise level in the working environment is effectively reduced, while also facilitating maintenance and adjustment.

[0020] The present application will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Example 1

[0022] like Figure 1 - Figure 3 As shown, the sound insulation and noise reduction device for the spindle box of a horizontal milling machine includes a mounting base 1, a mounting frame 6, a supporting sliding frame 7, a mineral fiber board 8, sound-absorbing holes 9, a fixing plate 10, and a pull plate 11. The mounting frame 6 for placing the milling machine spindle box is installed at the center of the upper end of the mounting base 1. The supporting sliding frame 7 is installed around the front end of the mounting frame 6. The mineral fiber board 8, which absorbs sound by converting sound energy into heat energy, is slidably connected inside the supporting sliding frame 7. Multiple sets of sound-absorbing holes 9 are linearly opened on the surface of the mineral fiber board 8 to absorb mid-to-high frequency noise using tiny pores. The fixing plate 10 is fixedly connected to the upper side of the front end of the mineral fiber board 8. The pull plate 11 for stretching the mineral fiber board 8 outward and connecting it with other devices is fixedly connected to the center of the upper surface of the fixing plate 10.

[0023] A support block 3 is fixedly connected to the center of the lower surface of the mounting frame 6, and a movable plate 2 is fixedly connected to the center of the lower surface of the support block 3. By setting the support block 3 and the movable plate 2, the stability of the mounting frame 6 is enhanced, which helps to distribute the weight evenly and reduce the shaking of the equipment during operation.

[0024] The movable plate 2 is fixedly connected to the two sides of the anti-collision plate 4. The upper inner side of the mounting base 1 is provided with a shock-absorbing pad 5 corresponding to the anti-collision plate 4. The combined use of the anti-collision plate 4 and the shock-absorbing pad 5 can effectively absorb and buffer the collision energy that may be generated, protect the device from damage and reduce noise.

[0025] During use, the mounting base 1 and mounting frame 6 provide a stable support structure, ensuring the entire device is sturdy and reliable, reducing additional noise caused by vibration. The mineral fiber board 8 is internally slidably connected through the support sliding frame 7, and its position can be adjusted as needed, effectively absorbing sound energy and converting it into heat energy. The sound-absorbing holes 9 on the surface of the mineral fiber board 8 absorb mid-to-high frequency noise using tiny pores. The fixing plate 10 and the pull plate 11 are used to conveniently pull the mineral fiber board 8 outward for maintenance or docking with other devices. Through the combined use of the anti-collision plate 4 and the shock-absorbing pad 5, the potential collision energy is effectively absorbed and buffered, protecting the device from damage and reducing noise.

[0026] Example 2

[0027] Based on Example 1, such as Figure 1 , Figure 4 and Figure 5 As shown, it also includes: a damping plate 12 and a mounting groove 13; the damping plate 12 is fixedly connected to the center of the mounting base 1. Multiple sets of mounting grooves 13 are opened from left to right on the center of the upper surface of the damping plate 12. The design of the damping plate 12 can significantly reduce the vibration transmitted to the base, while the mounting groove 13 provides a flexible component installation position, which is convenient for adjustment and maintenance.

[0028] A sliding column 14 is installed in the center of the mounting slot 13. A sliding cavity 15 is opened in the center of the sliding column 14. The design of the sliding column 14 and the sliding cavity 15 allows the internal components to move freely as needed to adapt to different working conditions.

[0029] A damping spring 16 is installed in the center of the sliding cavity 15. The damping spring 16 has a spring damper inside. The damping spring 16 and the spring damper work together to effectively absorb and dissipate vibration energy.

[0030] The upper end of the shock-absorbing spring 16 is equipped with a support column 17 that is fixedly connected to the movable plate 2. The support column 17 is slidably connected to the sliding column 14, which ensures that the movable plate 2 can move up and down smoothly when subjected to external force, thereby providing additional shock absorption while ensuring the normal operation of the equipment.

[0031] During use, the damping plate 12 is fixed to the center inside the mounting base 1, significantly reducing the vibration transmitted to the base. Multiple mounting slots 13 provide flexible component installation positions, facilitating adjustment and maintenance as needed. The damping spring 16 is installed in the center inside the sliding cavity 15, and a spring damper is provided. The two work together to absorb and dissipate vibration energy, effectively reducing the impact of noise and vibration on the equipment. This ensures normal operation of the equipment and provides additional damping effect, further enhancing the stability and seismic resistance of the entire device.
