Through the program control system, it can logically process programs specified by control codes or other symbolic instructions, control the movement of the machine tool, and automatically process parts according to the shape and size required by the drawing.

[0003] At present, the CNC turning and milling compound machine tools on the market are mainly modified for control system optimization. The existing CNC turning and milling compound machine tools are generally composed of machine tools, control systems, power systems and turning and milling boxes. After placing objects into the turning and milling box, the control system and power system are started to turn and mill the tool. However, the existing CNC turning and milling compound machine tools usually make loud and harsh metal cutting noises during turning and milling, which disturbs the workers. Therefore, it is proposed to use a CNC turning and milling compound machine tool with noise reduction function that can reduce the sound emitted to the outside during turning and milling through double-layer sound insulation to avoid the harsh sound affecting the work of personnel.

This solves the problem that the existing CNC turning and milling compound machine tools usually make loud and harsh metal cutting noises during turning and milling, which disturbs people.

[0005] In order to achieve the above-mentioned purpose of being able to reduce the sound emitted to the outside during turning and milling through double-layer sound insulation during turning and milling, and avoid the harsh sound affecting the work of personnel, the utility model provides the following technical solutions: a CNC turning and milling compound machine tool with noise reduction function, comprising a box body, a power box is fixedly installed on the left side of the box body, a control box is fixedly installed on the right side of the box body, a sound insulation mechanism is arranged inside the box body, and a base is fixedly installed on the bottom of the box body;

[0006] The sound insulation mechanism includes a turning and milling box, a vacuum layer, a sliding door, a sound-absorbing frame, a fixed plate, sound-absorbing holes, spikes, and a foam board. The turning and milling box is fixedly installed inside the box, and a vacuum layer is provided inside the turning and milling box. A sliding door is provided outside the box, and twenty-four sound-absorbing frames are fixedly installed inside the sliding door. Three fixed plates are fixedly installed inside the twenty-four sound-absorbing frames. Forty-eight sound-absorbing holes are provided inside the sliding door, and a number of spikes are fixedly installed on the inner walls of the forty-eight sound-absorbing holes. A foam board is fixedly installed inside the sliding door.

[0007] Furthermore, a movable groove adapted to the sliding door is provided on the outside of the power box, and an electromagnetic suction cup adapted to the sliding door is fixedly installed inside the control box.

[0008] Furthermore, a first sound-absorbing pattern is provided on the inner wall of the turning and milling box, and a second sound-absorbing pattern is provided on the outside of the turning and milling box.

[0009] Furthermore, sound-absorbing cotton is fixedly installed inside the power box and the control box. The two sound-absorbing cottons can prevent sound from being transmitted from the outside of the power box and the control box, which is beneficial to noise reduction.

[0010] Furthermore, the back and top of the box body are provided with sound-absorbing panels, and the two sound-absorbing panels can reduce the noise of secondary turning and milling.

[0011] Furthermore, a sand storage tank is provided inside the base, and fine sand is arranged inside the sand storage tank.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] The CNC turning and milling compound machine tool with noise reduction function is provided with a sound insulation mechanism. When it is necessary to turn and mill an object, the sliding door is slid to the left to the bottom, the object is placed in the turning and milling box, and then the sliding door is closed. The control box is operated to make the electric suction cup work to lock the sliding door, and then the turning and milling are carried out. The noise generated by the turning and milling is transmitted to the vacuum layer inside the turning and milling box for silencer. When the sound waves are transmitted to the sliding door, the fixed plate and spikes inside the sound absorbing frame consume most of the noise sound waves for the first silencer. Then, the remaining noise is transmitted to the sound absorbing board, the sound absorbing cotton and the foam board on the sliding door for the second silencer. The sound insulation mechanism can reduce the sound emitted to the outside during turning and milling through double-layer sound insulation during turning and milling, so as to avoid the harsh sound affecting the work of personnel.

The noise generated by the turning and milling is transmitted to the vacuum layer 402 inside the turning and milling box 401 for silencing. When the sound waves are transmitted to the sliding door 403, the fixed plate 405 and the spikes 407 inside the sound absorbing frame 404 consume most of the noise sound waves for the first silencing, and then the remaining noise is transmitted to the sound absorbing board, sound absorbing cotton and the foam board 408 on the sliding door 403 for secondary silencing. The sound insulation mechanism 4 can reduce the sound emitted to the outside during turning and milling through double-layer sound insulation during turning and milling, so as to avoid the harsh sound affecting the work of personnel.
