DETAILED DESCRIPTION

[0029] In order to make the purpose, scheme and advantages of the utility model more clear and apparent, the utility model is further described in detail below by combining with embodiments and drawings, and the illustrative embodiment and its description of the utility model are only used for explaining the utility model, and not as the limitation of the utility model.

[0030] In the following description, a large number of specific details are set forth in order to provide a thorough understanding of the utility model. However, it is apparent to those skilled in the art that the utility model can be implemented without adopting these specific details. In other embodiments, in order to avoid the confusion of the utility model, the well-known structures, circuits, materials or methods are not specifically described.

[0031] Reference throughout this specification to "one embodiment", "an embodiment", "one design", or "a design" means that a particular feature, structure, or characteristic described in connection with the embodiment or design is included in at least one embodiment of the application. The appearances of the phrases "in one embodiment", "in an embodiment", "in one design", or "in a design" in various places in the specification are not necessarily all referring to the same embodiment or design. Furthermore, the particular features, structures, or characteristics can be combined in any suitable

[0032] In the description of the application, the terms "front", "back", "left", "right", "top", "bottom", "vertical", "horizontal", "high", "low", "inner", "outer", and the like, indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the scope of protection of the application.

[0033] As shown in Figure 1 With Figure 2 As shown in FIG. 1, an embodiment provides a protective device applied to a lathe 6, which includes a visual protective plate 1 and an acoustic absorption protective assembly 2, the visual protective plate 1 is connected with the acoustic absorption protective assembly 2,

[0034] The acoustic absorption protective assembly 2 includes a first acoustic absorption protective plate 21, a second acoustic absorption protective plate 22 and a third acoustic absorption protective plate 23; one side of the first acoustic absorption protective plate 21 is used to connect with the top of the lathe 6 machining area shell, the other side of the first acoustic absorption protective plate 21 is connected with one side of the visual protective plate 1, the other side of the visual protective plate 1 is connected with one side of the second acoustic absorption protective plate 22, the other side of the second acoustic absorption protective plate 22 is connected with one side of the third acoustic absorption protective plate 23, and the other side of the third acoustic absorption protective plate 23 is used to connect with the bottom of the lathe 6 machining area shell.

[0035] For reference, industrial-grade structural adhesive (such as epoxy resin adhesive) can be used to bond the protective plates. Bolts or screws can also be used to secure the protective plates together. For example, holes are pre-drilled in the edges of each plate, and then they are fastened to the top and bottom of the lathe 6 machining area shell by screws.

[0036] As shown in Figure 2As shown, the first sound-absorbing protective plate 21, the second sound-absorbing protective plate 22 and the third sound-absorbing protective plate 23 all include a first protective layer 201, a sound-absorbing layer 202, a sound-insulating layer 203 and a second protective layer 204. The first protective layer 201, the sound-absorbing layer 202, the sound-insulating layer 203 and the second protective layer 204 are connected in sequence. The first protective layer 201 is used to block flying chips in the processing area of ​​the lathe 6.

[0037] For reference, the first protective layer 201 and the second protective layer 204 are made of metal. For example, stainless steel, aluminum alloy, or cold-rolled steel plate can be used. These metal materials have excellent strength and wear resistance, can effectively withstand the impact of flying chips generated during processing, and have good corrosion resistance, making them suitable for long-term use in industrial environments.

[0038] The sound absorbing layer 202 is filled with porous sound absorbing materials, such as glass fiber wool, mineral wool, and foam plastics, such as polyurethane foam.

[0039] Reference, such as Figure 3 As shown, a first sound insulation board 205 and a second sound insulation board 206 are provided in the sound insulation layer 203 , and the thickness of the first sound insulation board 205 and the second sound insulation board 206 are different.

[0040] The first sound insulation board 205 can be made of thinner sound insulation materials, such as PVC sound insulation board or rubber sound insulation board, which has good sound insulation performance and durability.

[0041] The second sound insulation board 206 can be made of a relatively thick material to enhance the overall sound insulation effect. For example, composite sound insulation board is composed of multiple layers of materials with different densities, such as wood, gypsum board, and sound insulation felt. Lead board or lead composite board, while heavier, provides excellent sound insulation.

[0042] Thicker sound insulation panels (such as second sound insulation panel 206) generally provide better insulation against low-frequency sounds. Low-frequency sounds have longer wavelengths and stronger penetration, requiring more mass to block them. Thinner sound insulation panels (such as first sound insulation panel 205) provide better insulation against high-frequency sounds. High-frequency sounds have shorter wavelengths, and thinner panels can effectively reflect and absorb these high-frequency sound waves. If all sound insulation layers 203 are of the same thickness, resonance may occur at certain frequencies, resulting in reduced sound insulation. By using panels of different thicknesses, the resonant frequencies can be staggered, reducing the possibility of resonance and improving the overall sound insulation effect.

[0043] Reference, such as Figure 4As shown, a hollow cavity 207 is formed between the sound insulation layer 203 and the sound absorption layer 202. The hollow cavity 207 can further isolate the propagation path of noise, improving the overall sound insulation effect.

[0044] For reference, as Figure 1 As shown, the visual protective plate 1 includes a plate body 11, and a plurality of observation windows 12 are arranged on the plate body 11. The material of the observation windows 12 is transparent PP material.

[0045] The visual protective plate 1 includes a solid plate body 11, and a plurality of observation windows 12 are uniformly distributed on the plate body 11. The observation windows 12 are made of transparent PP material, which has good transparency and impact resistance, effectively preventing the damage of flying chips generated during the machining of the lathe 6 to the observation windows 12, and ensuring that the line of sight of the operator is not hindered.

[0046] For reference, as Figure 5 As shown, the first sound absorption protective plate 21 and the visual protective plate 1 form a first machining avoidance area, the visual protective plate 1 and the second sound absorption protective plate 22 form a second machining avoidance area, and the second sound absorption protective plate 22 and the third sound absorption protective plate 23 form a third machining avoidance area.

[0047] By adjusting the connection angle between the visual protective plate 1 and the first sound absorption protective plate 21, the second sound absorption protective plate 22, and the third sound absorption protective plate 23, the size of the machining avoidance area can be changed. According to the machining requirements, the number of protective plates can also be increased or decreased, so as to change the range and shape of the machining avoidance area.

[0048] In summary, one side of the first sound absorption protective plate 21 is connected to the top of the lathe 6 machining area shell through bolts or other fasteners, and the other side is connected to one side of the visual protective plate 1 through welding or bolts. The first sound absorption protective plate 21 includes four layers of structure: a first protective layer 201, a sound absorption layer 202, a sound insulation layer 203, and a second protective layer 204. The first protective layer 201 is made of metal material, such as stainless steel or aluminum alloy, which is used to block the flying chips generated during the machining of the lathe 6. The sound absorption layer 202 is filled with porous sound absorption material, such as polyurethane foam or glass fiber, to absorb noise. The sound insulation layer 203 is provided with first sound insulation plate 205 and second sound insulation plate 206 with different thicknesses, which can further improve the sound insulation effect through the combination of different thicknesses. The second protective layer 204 is also made of metal material, which is used to enhance the strength and durability of the overall structure.

[0049] Example two provides a lathe 6 including the protective device of example one.

[0050] Specifically, as Figure 5 ,Figure 6 With Figure 7 As shown in the drawings, one side of the first sound-absorbing shield 21 is provided with a first connecting piece 44, and one side of the third sound-absorbing shield 23 is provided with a second connecting piece 55.

[0051] In a possible implementation, the first connecting piece 44 can be a clamping plate, and the lathe 66 is used to process a clamping groove on the top of the processing area shell, and the clamping plate and the clamping groove are in sliding connection. The second connecting piece 55 can also be a clamping plate, and the lathe 66 is used to process a clamping groove on the bottom of the processing area shell, and the clamping plate and the clamping groove are in sliding connection. In this way, the shielding device can also move left and right on the top of the processing area shell of the lathe 66.

[0052] As Figure 8 shown, in a possible implementation, the processing area of the lathe 66 can be completely sealed by two shielding devices. The noise control effect can be further improved, and the splashing of flying chips and cutting fluid generated during the processing of the lathe 66 can be effectively prevented from flying out of the processing area.

[0053] The above-described embodiments only express the specific implementation of the present application, and the description is more specific and detailed, but it cannot be understood as a limitation on the scope of the present application. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are all within the protection scope of the present application.
