Machining is one of the basic processes in the manufacturing industry and is widely used in various fields such as aviation, aerospace, automobiles, ships, and machinery manufacturing.

[0003] During the machining process, due to the high-speed cutting, grinding, polishing and other operations, significant noise will be generated. This noise will not only damage the hearing of the operator, but also interfere with the surrounding environment, affect the accuracy of other processes, and may even affect the lives of nearby residents. Utility Model Content

[0004] In order to overcome the above-mentioned defects, the utility model provides a noise control device for mechanical processing, which solves the problem that the mechanical processing process will generate significant noise, which will not only damage the hearing of the operator, but also the huge noise will interfere with the surrounding environment, affect the accuracy of other processes, and may even affect the lives of nearby residents.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a noise control device for mechanical processing, comprising a shell, an observation window is provided on the front of the shell, a sealing gasket is connected under the shell, a sound insulation pad is connected on the shell, a flap is rotatably connected to the outside of the shell, the flap is overlapped on the sound insulation pad, a handle is connected to the front of the flap, fixing devices are connected on both sides of the shell, a limiting device is connected to the front of the shell, the fixing device comprises a connecting plate, two suction cups are connected under the connecting plate, a fixing plate is connected on the suction cup, handles are connected inside the two fixing plates, a rotating plate is overlapped inside the fixing plate, a fixed shaft is connected through the rotating plate, and a sealing block is connected inside the rotating plate.

[0006] As a further solution of the utility model: the connecting plate is connected to one side of the shell, and the fixed shaft is connected in the fixing plate.

[0007] As a further solution of the utility model: the sealing block penetrates through and is slidably connected in the suction cup, and the rotating plate is overlapped on the suction cup.

[0008] As a further solution of the utility model: the limiting device includes a fixed block, the fixed block is connected to the front side of the shell, a long slot is opened in the fixed block, and an extrusion block is slidably connected in the long slot.

[0009] As a further solution of the utility model: the handle is clamped under the extrusion block, and the front side of the extrusion block is connected to a limiting plate.

[0010] As a further solution of the utility model: the back side of the limit plate is connected with a pull-back spring, and the pull-back spring is connected to the front side of the fixed block.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. The noise control device in mechanical processing is provided with a connecting plate, a suction cup, a fixed plate, a handle, a fixed shaft, a rotating plate and a sealing block. When it is necessary to reduce the noise of the processing equipment, the shell is set outside the processing equipment, and then the handle is pressed. The handle applies pressure to the fixed plate, and the pressure drives the fixed plate to move. At this time, after the suction cup is subjected to pressure, the air in the suction cup is released on the workbench. At this time, the rotating plate is pulled, and the rotating plate rotates through the fixed shaft. The rotating plate drives the sealing block to move. At this time, the sealing block slides into the suction cup to seal the suction cup. At this time, the suction cup is in a vacuum state. When the shell needs to be removed, it only needs to rotate the rotating plate in the opposite direction. The rotating plate drives the sealing block away from the suction cup when rotating. At this time, the pressure inside the suction cup is rapidly reduced, so that the suction cup is released from the workbench. At this point, the noise reduction of the processing equipment is completed, and the significant noise generated during the mechanical processing process is avoided. This noise will not only damage the hearing of the operator, but also the huge noise will interfere with the surrounding environment, affect the accuracy of other processes, and may even affect the lives of nearby residents.

[0013] 2. The noise control device in the mechanical processing is provided with a fixed block, a long groove, an extrusion block, a limit plate and a pull-back spring. When the workpiece is replaced, the handle is pulled at this time, and the handle drives the flip cover to rotate. When the handle and the extrusion block apply pressure, the extrusion block slides in the fixed block after being subjected to pressure. When the handle slides under the extrusion block, the pull-back spring applies elastic force to the limit plate, and the elastic force drives the limit plate to move, and the limit plate drives the extrusion block to move, so that the extrusion block is quickly reset, thereby limiting the handle and the shell. At this time, the flip cover is stuck on the sound insulation pad, which avoids the problem of poor sound insulation effect caused by noise coming out from the flip cover during processing.

DETAILED DESCRIPTION

[0019] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0020] like Figure 1-4 As shown, the utility model provides a technical solution: a noise control device in mechanical processing, comprising a shell 1, an observation window 2 is arranged on the front of the shell 1, a sealing pad 3 is connected to the bottom of the shell 1, a sound insulation pad 4 is connected to the top of the shell 1, a flip cover 5 is rotatably connected to the outside of the shell 1, the flip cover 5 is overlapped on the sound insulation pad 4, a handle 6 is connected to the front of the flip cover 5, both sides of the shell 1 are connected with fixing devices 7, the front of the shell 1 is connected with a limiting device 8, the limiting device 8 comprises a fixing block 81, the fixing block 81 is connected to the front of the shell 1, a long groove 82 is opened in the fixing block 81, an extrusion block 83 is slidably connected in the long groove 82, the handle 6 is clamped under the extrusion block 83, by setting the extrusion block 83 and the handle 6, the extrusion block 83 cooperates with the handle 6, so that the extrusion block 83 limits the handle 6, and avoids the handle 6 from shaking or falling off during processing;

[0021] The front of the extrusion block 83 is connected to a limit plate 84, and the back of the limit plate 84 is connected to a pull-back spring 85. By setting the pull-back spring 85, when processing, the pull-back spring 85 applies elastic force to the limit plate 84 to keep it stable. When the handle 6 is away from the extrusion block 83, the pull-back spring 85 applies elastic force to the limit plate 84, and the elastic force drives the limit plate 84 and the extrusion block 83 to move, so that they can be quickly reset.

[0022] The pull-back spring 85 is connected to the front of the fixing block 81. The fixing device 7 includes a connecting plate 71, which is connected to one side of the housing 1. The fixing shaft 75 is connected to the fixing plate 73. Two suction cups 72 are connected under the connecting plate 71. The suction cups 72 are connected to the fixing plate 73. The two fixing plates 73 are connected to the handles 74. The fixing plates 73 are overlapped with a rotating plate 76. The rotating plate 76 is connected with the fixing shaft 75. The rotating plate 76 is connected with a sealing block 77. By setting the sealing block 77 and the suction cup 72, the sealing block 77 cooperates with the suction cup 72, so that the sealing block 77 can seal the suction cup 72 to prevent air from entering the suction cup 72 during processing.

[0023] The sealing block 77 penetrates through and is slidably connected in the suction cup 72 , and the rotating plate 76 overlaps the suction cup 72 .

[0024] The working principle of the utility model is:

[0025] When it is necessary to reduce the noise of the processing equipment, the shell 1 is placed outside the processing equipment, and then the handle 74 is pressed. The handle 74 applies pressure to the fixed plate 73, and the pressure drives the fixed plate 73 to move. At this time, after the suction cup 72 is under pressure, the air in the suction cup 72 is released. At this time, the rotating plate 76 is pulled, and the rotating plate 76 rotates through the fixed shaft 75. The rotating plate 76 drives the sealing block 77 to move. At this time, the sealing block 77 slides into the suction cup 72 to seal the suction cup 72. At this time, the suction cup 72 is in a vacuum state. When the shell 1 needs to be removed, it is only necessary to rotate the rotating plate 76 in the opposite direction. The rotating plate 76 drives the sealing block 77 when rotating. 7 is away from the suction cup 72, and the pressure inside the suction cup 72 is rapidly reduced, so that the suction cup 72 is released from the fixation with the workbench. When the workpiece is replaced, the handle 6 is pulled, and the handle 6 drives the flip cover 5 to rotate. When the handle 6 and the extrusion block 83 apply pressure, the extrusion block 83 is subjected to pressure and slides in the fixed block 81. When the handle 6 slides under the extrusion block 83, the pull-back spring 85 applies elastic force to the limit plate 84, and the elastic force drives the limit plate 84 to move, and the limit plate 84 drives the extrusion block 83 to move, so that the extrusion block 83 is quickly reset, thereby completing the noise reduction of the processing equipment.

[0026] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connection", "sliding connection" and "hinge" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0027] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
