Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-4 The utility model provides a technical solution: a noise reduction structure of a nut remover, comprising a working machine 1, on the top of which are installed a control component 200 for controlling and a disassembly component 300 for disassembling; through the use of the working machine 1 and the disassembly component 300, a good noise reduction effect can be achieved on the power source, and by providing a sound insulation structure and a through hole for sound absorption, the internal noise can be effectively absorbed and is not easily transmitted to the outside, thereby avoiding the impact on the external environment, and at the same time, the temperature of the power source can be conducted through the heat conduction structure, thereby improving the heat dissipation capacity of the power source, making it suitable for long-term work, thereby greatly improving the practical performance of the nut remover.

[0025] In this embodiment, the disassembly assembly 300 is a structure used for disassembling the nut and for reducing the noise of the power source.

[0026] like Figure 2 , Figure 3 and Figure 4As shown, the disassembly assembly 300 includes a plurality of grip tubes 301, a support block 302 fixed to the inner side of the grip tube 301, a transmission rod 303 rotatably connected to the inner side of the grip tube 301 through a bearing, a connecting shell 304 fixed to the bottom end of the transmission rod 303, a disassembly tube 305 detachably connected to the inner side of the connecting shell 304, a driving mechanism 306 fixedly mounted on the top of the grip tube 301 and used to drive the transmission rod 303 to rotate, a plurality of heat sinks 307 fixedly mounted on the outer side of the driving mechanism 306, a plurality of ventilation holes 308 opened on the outer side of the heat sink 307, a shell 309 fixed to the top of the grip tube 301 and located on the outer side of the driving mechanism 306, a first sound insulation pad 310 bonded to the inner side of the shell 309, a second sound insulation pad 311 bonded to the inner side of the first sound insulation pad 310, and a plurality of sound absorption holes 312 opened between the outer sides of the first sound insulation pad 310 and the second sound insulation pad 311.

[0027] It should be noted that the bottom end of the transmission rod 303 passes through the bottom of the corresponding support block 302 and the bottom of the grip tube 301 in sequence, and the outer side of the transmission rod 303 is rotatably connected to the top and bottom of the corresponding support block 302 through two bearings, so that the support block 302 can support the transmission rod 303 so that it can transmit stably. The output end of the driving mechanism 306 passes through the top of the corresponding grip tube 301 and is fixedly connected to the top of the transmission rod 303. The driving mechanism 306 can be a small servo motor, so that the driving mechanism 306 can drive the transmission rod 303 to rotate.

[0028] In addition, the outer side of the disassembly cylinder 305 is connected to the inner side of the connecting shell 304 by screws, the bottom of the disassembly cylinder 305 is open, and the inner side of the disassembly cylinder 305 is a regular hexagon, so that the disassembly cylinder 305 can be replaced to suit the disassembly of nuts of different models.

[0029] At the same time, the top of the heat sink 307 passes through the second sound insulation pad 311, the first sound insulation pad 310 and the outer shell 309 in sequence, so that the surface of the heat sink 307 can be in contact with the outside world, thereby playing a role in heat dissipation and heat conduction. The first sound insulation pad 310 is an industrial sponge pad, and the second sound insulation pad 311 is a polyurethane sound insulation pad, so that the first sound insulation pad 310 and the second sound insulation pad 311 can cooperate with the sound absorption hole 312 to play a role in sound absorption and sound insulation.

[0030] In this embodiment, the control component 200 is a structure used for startup control and signal transmission.

[0031] like Figure 1As shown, the control component 200 includes a plurality of columns 201 fixed on the top of the work machine 1, a top plate 202 fixed between the tops of the plurality of columns 201, a plurality of controller bodies 203 fixedly installed on the top of the top plate 202, and a plurality of connecting holes 204 opened on the top of the top plate 202 and located below the corresponding controller bodies 203.

[0032] It should be noted that the number of grips 301 is equal to the number of controller bodies 203. A cable is fixedly installed between the output end of the controller body 203 and the input end of the drive mechanism 306. The cable is located inside the corresponding connecting hole 204. The ends of the cable pass through the corresponding outer shell 309, the first sound insulation pad 310 and the outside of the second sound insulation pad 311 in sequence, so that the controller body 203 can transmit relevant signals to the drive mechanism 306 through the cable to make it work. The controller body 203 can be a PLC programmable controller, and signal transmission and control can be achieved through simple programming.

[0033] The working principle of the above embodiment is:

[0034] When removing the nut, the workpiece to be removed is placed on the top of the workbench 1, the grip tube 301 is held, the removal tube 305 is sleeved on the outside of the nut, the driving mechanism 306 is started, and the transmission rod 303 is driven to rotate, so that the connecting shell 304 and the removal tube 305 are rotated, and the nut can be rotated and removed. Under the action of the first sound insulation pad 310 and the second sound insulation pad 311, the noise generated by the driving mechanism 306 can be effectively isolated. At the same time, under the action of the sound-absorbing hole 312, the hole structure is used to replenish the sound source, and the friction between the air and the inner wall of the sound-absorbing hole 312 is used to consume the sound energy, thereby further reducing the transmission of noise. Moreover, under the cooperation between the heat sink 307 and the vent hole 308, the heat on the outside of the driving mechanism 306 can be transferred, thereby exchanging heat with the outside air, achieving good passive heat dissipation capability, and ensuring that the driving mechanism 306 is in a stable working state for a long time.

[0035] Compared with the prior art, the noise reduction structure of the nut remover, through the use of the working machine 1 and the disassembly component 300, can achieve a good noise reduction effect on the power source. By setting a sound insulation structure and a through hole for sound absorption, the internal noise can be effectively absorbed and is not easily transmitted to the outside, thereby avoiding the impact on the external environment. At the same time, the temperature of the power source can be conducted through the heat conduction structure, thereby improving the heat dissipation capacity of the power source and making it suitable for long-term work, thereby greatly improving the practical performance of the nut remover and solving the problem that the existing nut removers make excessive noise when working together, affecting the working environment.

[0036] The electrical components appearing in the article are all electrically connected to the main controller and the main power supply. The provision of power supply is common knowledge in the field. The main controller can be a conventional known device that controls a computer, etc., which can be implemented through simple programming by technicians in the field. They are all existing publicly available power connection technologies and will not be described in detail in the article.
