[0001] The utility model belongs to the technical field of mechanical parts processing, in particular to a noise reduction device used for mechanical parts processing. Background Art

[0002] Mechanical parts processing refers to the process of removing, adding or changing the shape, size and performance of raw materials through various mechanical processing methods in order to manufacture mechanical parts that meet the design and use requirements. During the processing of mechanical parts, considerable noise is often generated. These noises may come from rotating mechanical parts, friction between cutting edges and workpieces, high-speed motors, etc. Operators in the workshop may suffer from continuous noise interference if exposed to the noise environment for a long time, which will not only have an adverse effect on their mental health, but may also cause long-term damage to their hearing. Utility Model Content

[0003] In order to overcome the above-mentioned defects, the utility model provides a noise reduction device for mechanical parts processing, which solves the problem that considerable noise is often generated during the processing of mechanical parts. Operators in the workshop may suffer from continuous noise interference due to long-term exposure to the noise environment, causing long-term damage to their hearing.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a noise reduction device for machining mechanical parts, comprising a bottom plate, a machining assembly connected to the bottom plate, a noise reduction device connected to the bottom plate, fixing devices connected to both sides of the noise reduction device, and the noise reduction device comprising a fixing shell;

[0005] A limiting groove is provided in the fixed shell, a limiting block is provided in the limiting groove, a movable shell is connected to the front of the limiting block, sound insulation boards are installed in both the movable shell and the fixed shell, an observation window is provided in the movable shell, and two handles are connected to the front of the movable shell.

[0006] As a further solution of the utility model: the fixed shell is connected to the bottom plate, and the movable shell is overlapped outside the bottom plate.

[0007] As a further solution of the utility model: the sound insulation board is overlapped on the bottom plate, and the observation window corresponds to the position of the processing component.

[0008] As a further solution of the utility model: the fixing device includes a fixing block, the fixing block is connected to one side of the fixing shell, a sliding groove is opened in the fixing block, one side of the fixing block is connected to a connecting plate, a limiting rod is slidably connected in the connecting plate, and one side of the limiting rod is connected to an extrusion block.

[0009] As a further solution of the utility model: the outer sleeve of the limit rod is provided with a pull-back spring, one end of the pull-back spring is connected to one side of the connecting plate, and the other end of the pull-back spring is connected to one side of the extrusion block.

[0010] As a further solution of the utility model: a movable plate is provided outside the extrusion block, a through hole is provided inside the movable plate, and the extrusion block is disposed in the through hole.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The noise reduction device for machining mechanical parts is provided with a fixed shell, a limit groove, a limit block, a movable shell, a sound insulation board, an observation window and a handle. When machining is required, the handle is held, and then the movable shell is pushed to move. The movable shell drives the limit block and the sound insulation board to move. Then the limit block is stuck in the limit groove. At this time, the two sound insulation boards overlap. This improvement effectively reduces the generation of noise in the machining environment, thereby ensuring that the operators will not be subjected to high-intensity noise for a long time during work, which helps to protect their hearing health and create a quieter and more suitable working environment.

[0013] 2. The noise reduction device for machining mechanical parts is provided with a fixed block, a slide groove, a connecting plate, a limit rod, an extrusion block, a pull-back spring, a movable plate and a through hole. When the movable shell is overlapped with the fixed shell, the movable shell drives the movable plate to move, and then the movable plate applies a thrust to the extrusion block, and the thrust drives the extrusion block to move. Then, when the extrusion block corresponds to the position of the through hole, the pull-back spring applies an elastic force to the extrusion block, and the elastic force drives the extrusion block to move. At this time, the extrusion block is stuck in the through hole, thereby completing the fixation of the movable shell during noise reduction and avoiding shaking during machining, which affects the stability of the movable shell.
