Technical Field
[0001] This utility model relates to the field of machine tool technology, and in particular to a noise-reducing machine tool. Background Technology
[0002] Machine tools are the core equipment in manufacturing machines. They achieve machining through the relative movement of the cutting tool and the workpiece. They are important equipment for modern precision machining. During the machining process, machine tools generate high-intensity noise due to vibration, friction and aerodynamic effects. Long-term exposure can easily lead to hearing damage to operators.
[0003] Currently, the sound insulation and noise reduction measures for machine tools usually involve installing soundproof covers and doors around the machine tool's working area. These measures can effectively isolate and absorb noise, but internal heat dissipation is required, and some noise will still be transmitted through the fans and heat dissipation holes, resulting in a decrease in the noise reduction effect.
[0004] Therefore, the current sound insulation and noise reduction measures for machine tools typically involve installing soundproof covers and doors around the machine tool's working area. These measures effectively isolate and absorb noise, but internal heat dissipation is still required, and some noise will still escape through the fans and ventilation holes, resulting in a decrease in noise reduction effectiveness. A noise reduction-type machine tool could be designed to effectively prevent noise from escaping through the fans and ventilation holes, ensuring a better noise reduction effect. Utility Model Content
[0005] To overcome the current noise reduction measures for machine tools, soundproof covers and doors are usually installed around the machine tool's working area. These can effectively isolate and absorb noise, but internal heat dissipation is required, and some noise will still be transmitted through the fan and heat dissipation holes, resulting in a decrease in the noise reduction effect.
[0006] The technical solution of this utility model is as follows: a noise-reducing machining tool, including a machine tool body, a working cavity, soundproof doors, a fan, and a support assembly. The working cavity is opened inside the machine tool body. The fan is fixedly installed above the machine tool body and communicates with the working cavity. Two sets of guide plates are fixedly installed on the top surface inside the working cavity. The two sets of guide plates are located on both sides of the fan and are symmetrically arranged. A connecting rod is fixedly installed below the top surface inside the working cavity. The connecting rod is located around the fan. A baffle is fixedly installed below the connecting rod. The baffle has an inverted triangular cross-section. The lower surfaces of the baffle and the guide plates are provided with corrugated patterns. Two sets of soundproof doors are provided on one side of the machine tool body. The side walls of the soundproof doors have reserved grooves. Multiple sets of ventilation holes are opened on the side walls of the soundproof doors and communicate with the reserved grooves. Two sets of support assemblies are provided and are located below the machine tool body.
[0007] Preferably, a soundproof door can be installed to shield and protect the working chamber, thereby hindering and absorbing the noise generated during operation. A fan, in conjunction with ventilation holes, can exchange air within the working chamber, ensuring stable internal temperature. A baffle is installed via a connecting rod, which can shield the fan, preventing sound from directly propagating to the fan and out of the working chamber, thus reducing the noise reduction effect. The inverted triangular structure of the baffle, in conjunction with the guide plate, can guide airflow, preventing airflow from being blocked by the baffle and affecting ventilation and heat dissipation. The corrugated pattern on the lower surface of the baffle and guide plate can reflect and absorb noise in multiple directions. A pre-reserved slot can connect the heat dissipation hole and the internal support of the working chamber, ensuring air circulation and simultaneously shielding the ventilation hole to prevent sound from directly escaping through it.
[0008] Preferably, the inner sidewall of the working chamber is provided with a rock wool layer, and the outer periphery of the rock wool layer is provided with a microporous aluminum plate layer.
[0009] Preferably, the soundproof door has two sets of tempered glass fixedly installed inside, with a vacuum cavity between the two sets of tempered glass.
[0010] Preferably, a slide rail is fixedly installed on one side of the machine tool body, and a soundproof door is located above the slide rail. The soundproof door is slidably connected to the slide rail, and a handle is fixedly installed on one side of the soundproof door.
[0011] Preferably, a magnetic strip is fixedly installed on one side of the soundproof door, and a sealing sleeve is fixedly installed around the magnetic strip.
[0012] Preferably, the support assembly includes a slide groove and a support leg. Two sets of slide grooves are provided on the lower part of the machine tool body. The two sets of slide grooves are arranged symmetrically. The support leg is located on the lower part of the machine tool body and is slidably connected to the slide groove.
[0013] Preferably, multiple sets of air springs are fixedly installed between the support legs and the machine tool body, and anti-slip rubber pads are fixedly installed under the support legs.
[0014] The beneficial effects of this utility model are:
[0015] 1. During processing, the air exchange between the working chamber and the external environment can be achieved through the ventilation holes opened on the side wall of the soundproof door using a fan, thereby ensuring the temperature stability inside the working chamber. The baffle is installed through the connecting rod, which can shield the fan and prevent sound from being directly transmitted to the fan and out of the working chamber. The inverted triangular structure of the baffle and the guide plate can guide the airflow and prevent the airflow from being blocked by the baffle, which would affect ventilation and heat dissipation. The corrugated pattern on the lower surface of the baffle and guide plate can reflect and absorb noise in multiple directions, further absorbing noise.
[0016] 2. The ventilation holes on the side wall of the soundproof door do not directly connect to the working chamber, but rather connect to the working chamber through a reserved groove. The openings of the reserved grooves that connect to the working chamber do not correspond to the ventilation holes, which can block noise and prevent noise from being transmitted directly through the ventilation holes, effectively reducing the impact of noise.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0024] Please see Figure 3 and Figure 4This utility model provides an embodiment: a noise-reducing machining tool, including a machine tool body 1, a working chamber 2, a soundproof door 3, a fan 4, and a support assembly. The working chamber 2 is opened inside the machine tool body 1. The fan 4 is fixedly installed above the machine tool body 1 and communicates with the working chamber 2. Two sets of guide plates 401 are fixedly installed on the top surface inside the working chamber 2. The two sets of guide plates 401 are located on both sides of the fan 4 and are symmetrically arranged. A connecting rod is fixedly installed below the top surface inside the working chamber 2. 402, connecting rod 402 is located on the periphery of fan 4, and baffle 403 is fixedly installed below connecting rod 402. The cross-section of baffle 403 is an inverted triangular structure. The lower surfaces of baffle 403 and guide plate 401 are both provided with corrugated patterns. Two sets of soundproof doors 3 are provided on one side of machine tool body 1. The side wall of the soundproof door 3 is provided with a reserved groove 303. Multiple sets of ventilation holes 304 are provided on the side wall of the soundproof door 3. The ventilation holes 304 are connected to the reserved groove 303. Two sets of support components are provided. The support components are set on the machine tool body 1. Below the bed body 1, a soundproof door 3 can be installed to shield and protect the working chamber 2, thereby hindering and absorbing the noise generated during the operation of the working chamber 2. A fan 4, in conjunction with the ventilation hole 304, can exchange air inside the working chamber 2 to ensure stable internal temperature. A connecting rod 402 is installed to install a baffle 403, which can shield the fan 4 to prevent sound from directly propagating to the fan 4 and out of the working chamber 2, thus reducing the noise reduction effect. The inverted triangular structure of the baffle 403 and the guide plate 401 can guide the airflow to prevent the airflow from being blocked by the baffle 403 and affecting ventilation and heat dissipation. The corrugated pattern on the lower surface of the baffle 403 and the guide plate 401 can reflect and absorb noise in multiple directions. A reserved slot 303 can be installed to connect the heat dissipation hole and the internal support of the working chamber 2 to ensure air circulation, while also shielding the ventilation hole 304 to prevent sound from directly escaping through the ventilation hole 304.
[0025] Please see Figure 2 In this embodiment, a rock wool layer 201 is provided on the inner sidewall of the working chamber 2, and a microporous aluminum plate layer 202 is provided on the periphery of the rock wool layer 201. The rock wool layer 201 can absorb noise, and the microporous aluminum plate layer 202 can protect the rock wool layer 201. At the same time, the micropores on the surface can also absorb noise.
[0026] Please see Figure 1 , Figure 4 and Figure 5In this embodiment, two sets of tempered glass 301 are fixedly installed inside the soundproof door 3, and a vacuum cavity 302 is provided between the two sets of tempered glass 301. The tempered glass 301 allows the operator to easily observe the inside of the working chamber 2, and the vacuum cavity 302 between the two sets of tempered glass 301 can effectively block noise and prevent noise from escaping from the tempered glass 301. A slide rail 307 is fixedly installed on one side of the machine tool body 1, and the soundproof door 3 is located above the slide rail 307, with the soundproof door 3 slidably connected to the slide rail 307. A handle 308 is fixedly installed on one side of the soundproof door 3; the handle 308 allows the soundproof door 3 to be easily pulled along the slide rail 307, thus enabling the soundproof door 3 to be opened and closed freely; a magnetic strip 305 is fixedly installed on one side of the soundproof door 3, and a sealing sleeve 306 is fixedly installed around the magnetic strip 305; the magnetic strip 305 fixes the two sets of soundproof doors 3 when the soundproof door 3 is closed, and the sealing sleeve 306 makes the two sets of soundproof doors 3 close more tightly, reducing the amount of sound leakage through the door gap.
[0027] Please see Figure 3 In this embodiment, the support assembly includes a slide groove 501 and a support leg 502. Two sets of slide grooves 501 are provided on the lower part of the machine tool body 1, and the two sets of slide grooves 501 are symmetrically arranged. The support leg 502 is located on the lower part of the machine tool body 1 and is slidably connected to the slide groove 501. Multiple sets of air springs 503 are fixedly installed between the support leg 502 and the machine tool body 1. An anti-slip pad 504 is fixedly installed on the lower part of the support leg 502. The support leg 502 supports the machine tool body 1. The air springs 503 can absorb the vibration generated when the machine tool body 1 is working. The slide groove 501 can limit the support leg 502 to make it more stable. The anti-slip pad 504 is in direct contact with the ground, which can make the support leg 502 fit the ground better and reduce the noise transmitted to the ground.
[0028] When working, when processing is required, the handle 308 can be used to pull the two sets of soundproof doors 3 to slide along the slide rail 307 and close them, thereby enclosing the working chamber 2 into a relatively closed space, thus isolating the noise inside the working chamber 2. When the soundproof doors 3 are closed, the magnetic strip 305 fixes the two sets of soundproof doors 3, and the sealing sleeve 306 can make the two sets of soundproof doors 3 close more tightly, reducing the amount of sound leakage from the door gaps. The rock wool layer 201 installed on the side wall of the working chamber 2 can absorb noise, and the microporous aluminum plate layer 202 can protect the rock wool layer 201. At the same time, the micropores on the surface can also absorb noise.
[0029] By utilizing the ventilation holes 304 opened on the side wall of the soundproof door 3 in conjunction with the fan 4, air exchange between the inside of the working chamber 2 and the external environment can be achieved, thereby ensuring the temperature stability inside the working chamber 2. The baffle 403 is installed through the connecting rod 402, which can shield the fan 4 and prevent sound from being directly transmitted to the fan 4 and out of the working chamber 2. Through the inverted triangular structure of the baffle 403 and the cooperation of the guide plate 401, the airflow can be guided to prevent the airflow from being blocked by the baffle 403 and affecting ventilation and heat dissipation. The corrugated pattern on the lower surface of the baffle 403 and the guide plate 401 can reflect and absorb noise in multiple directions, further absorbing noise.
[0030] The ventilation hole 304 on the side wall of the soundproof door 3 does not directly connect with the working chamber 2, but connects with the working chamber 2 through the reserved groove 303. By utilizing the fact that the opening of the reserved groove 303 that connects with the working chamber 2 does not correspond to the ventilation hole 304, noise can be blocked, preventing noise from being transmitted directly through the ventilation hole 304, and effectively reducing the impact of noise.
[0031] When the machine tool body 1 is working, the tempered glass 301 allows the operator to easily observe the inside of the working chamber 2. The vacuum chamber 302 between the two sets of tempered glass 301 can effectively block noise and prevent noise from being transmitted from the tempered glass 301. The air spring 503 can absorb the vibration generated when the machine tool body 1 is working, reducing the noise generated by the vibration of the machine tool body 1. The anti-slip rubber pad 504 is in direct contact with the ground, which can make the support leg 502 fit more closely to the ground and reduce the noise transmitted to the ground.
[0032] Through the above steps, the baffle 403 is installed via the connecting rod 402. The baffle 403 can shield the fan 4, preventing sound from directly propagating to the fan 4 and exiting the working chamber 2. Through the cooperation of the inverted triangular structure of the baffle 403 and the guide plate 401, the airflow can be guided, preventing the airflow from being blocked by the baffle 403 and affecting ventilation and heat dissipation. Through the wave pattern set on the lower surface of the baffle 403 and the guide plate 401, noise can be reflected and absorbed in multiple directions, further absorbing noise. This solves the problem that current sound insulation and noise reduction measures for machine tools usually involve installing soundproof covers and soundproof doors 3 around the machine tool's working area, which can effectively isolate and absorb noise. However, internal heat dissipation is required, and some noise will still be transmitted from the fan 4 and heat dissipation holes, resulting in a deterioration in noise reduction effect.
[0033] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
