Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to a noise-reducing electric cylinder. Background Art

[0002] With the outbreak of the Industrial Revolution, a large number of mechanical equipment appeared. The emergence of mechanical equipment has changed people's lives, made people's lives and work more convenient, and improved the quality of life. The electric cylinder is a common and important mechanical equipment. Its main function is to drive other devices to change their positions in space. However, it still has the following disadvantages in actual use:

[0003] 1. When the existing noise reduction electric cylinder is in use, the electric cylinder will generate noise during operation due to the mutual friction of the internal parts. If the staff is in a noisy environment for a long time, it may cause migraines and insomnia. In severe cases, it may also cause chest tightness, shortness of breath and other symptoms, which endangers the health of the staff. The existing electric cylinder cannot eliminate the noise, so it is not convenient to use;

[0004] 2. When the existing noise reduction electric cylinder is in use, the internal heat dissipation of the electric cylinder mainly relies on the heat dissipation holes. However, when the electric cylinder is in high-intensity operation, the internal heat accumulation increases, causing the temperature inside the shell to rise, thereby affecting the working life of the servo motor and increasing the maintenance cost, so it is not convenient to use.

[0005] In the prior art, a Chinese patent with a publication number of CN215634101U is proposed to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: A noise reduction electric cylinder, which relates to the technical field of mechanical equipment. The utility model includes a lower shell, a cooling assembly and a driving assembly are arranged inside the lower shell, the top of the lower shell is fixedly connected to the upper shell by bolts, a sound absorbing board is fixedly connected to the inner wall of the upper shell, and sound absorbing holes are evenly opened on the surface of the sound absorbing board, and the cooling assembly includes a mounting shell, a motor and a fan blade, the mounting shell is fixedly connected to the inner bottom of the lower shell, the inner bottom of the mounting shell is fixedly connected to the motor, the output shaft of the motor is sleeved with fan blades, the output shaft of the motor is movably connected to the lower surface of the mounting plate, and the mounting plate is fixedly connected to the upper inner side of the mounting shell. The utility model consumes noise energy through the sound absorbing holes on the sound absorbing board by using the sound absorbing board and the cooling assembly, thereby achieving the effect of noise reduction, and at the same time, the fan blade drives the air flow to accelerate the heat dissipation of the servo motor, thereby enhancing the heat dissipation performance.

[0006] However, since the upper shell of the device is sleeved on the outside of the output rod, when the noise reduction component of the device needs to be maintained or replaced, the output rod and the device on which it is installed need to be removed before subsequent work can be carried out, which is too troublesome. Utility Model Content

One side of the electric cylinder base is plugged into the outer wall of the limit plug plate through a supporting frame plate, and the upper surface of the supporting frame plate is fixedly connected to the limit plug plate through bolts.

[0012] A further improvement of the technical solution of the utility model is that one end of the silencer fin is fixedly connected to the inner wall of the silencer chamber, one side of the other end of the silencer fin is fixedly connected to an auxiliary spring, and one end of the auxiliary spring away from the silencer fin is fixedly connected to the inner wall of the silencer chamber.

[0013] A further improvement of the technical solution of the utility model is that: the number of the silencer fins is several, and the several silencer fins are distributed on the inner wall of the silencer chamber in pairs.

[0014] A further improvement of the technical solution of the utility model is that the inner walls of the first noise reduction closed shell and the second noise reduction closed shell are both fixedly connected with sound absorbing panels.

[0015] A further improvement of the technical solution of the utility model is that an adjustment installation groove is provided on the upper surface of the limit plug plate.

[0020] 2. The utility model provides a noise-reducing electric cylinder, which utilizes the coordinated use of a noise-reducing chamber, noise-reducing fins and an auxiliary spring, so that during the use of the electric cylinder body, the noise generated by the noise-reducing fins will be dispersed by the arrangement structure of the noise-reducing fins in the process of spreading outwards. At the same time, when the vibration is transmitted to the noise-reducing fins, the noise-reducing fins will vibrate under force, and at this time the auxiliary spring will utilize its deformation elastic force to offset the vibration of the noise-reducing fins, thereby enabling the noise-reducing fins to absorb the noise, and at the same time cooperate with the sound-absorbing panel to further enhance the noise reduction effect of the device.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] The present invention is further described in detail below in conjunction with the embodiments:

[0029] Example 1

[0030] like Figure 1-5 As shown, the utility model provides a noise reduction electric cylinder, comprising an electric cylinder body 1, a closed noise reduction component 2 and an electric cylinder base 3, wherein the closed noise reduction component 2 comprises a first noise reduction closed shell 4 and a second noise reduction closed shell 5 which are sleeved on the outer wall of the electric cylinder body 1 and are used to reduce the noise of the electric cylinder body 1;

[0031] The outer wall of the first noise reduction closed shell 4 is movably connected with a connecting piece 6, and the first noise reduction closed shell 4 is fixedly connected with the second noise reduction closed shell 5 by bolts installed on the connecting piece 6. The inner wall of the first noise reduction closed shell 4 is provided with a muffler chamber 8 for muffler, and the inner wall of the muffler chamber 8 is fixedly connected with a muffler fin 9;

[0032] The bottom end of the second noise reduction enclosure 5 is fixedly connected with a limit plug plate 10 for docking and installation with the electric cylinder base 3. One side of the electric cylinder base 3 is plugged with the outer wall of the limit plug plate 10 through a receiving frame 11, and the upper surface of the receiving frame 11 is fixedly connected with the limit plug plate 10 through bolts. The staff removes the bolts installed on the connecting piece 6, and removes them in sequence until the last group of connecting pieces 6 is removed, and then removes the bolts on the receiving frame 11, and then the first noise reduction enclosure 4 and the second noise reduction enclosure 5 can be pulled outward along the end of the receiving frame 11, and removed from the electric cylinder body 1, and then the first noise reduction enclosure 4 and the second noise reduction enclosure 5 can be maintained or replaced.

[0033] Example 2

[0034] like Figure 1-5As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, one end of the silencer fin 9 is fixedly connected to the inner wall of the silencer chamber 8, and the other end of the silencer fin 9 is fixedly connected to an auxiliary spring 13, and the end of the auxiliary spring 13 away from the silencer fin 9 is fixedly connected to the inner wall of the silencer chamber 8. During the use of the electric cylinder body 1, the noise generated by it will be dispersed by the arrangement structure of the silencer fin 9 during the process of spreading outward. At the same time, when the vibration is transmitted to the silencer fin 9, the silencer fin 9 is vibrated by force, and at this time, the auxiliary spring 13 will use its deformation elastic force to offset the vibration of the silencer fin 9, thereby enabling the silencer fin 9 to absorb the noise.

[0035] There are a plurality of silencer fins 9 , and the silencer fins 9 are distributed on the inner wall of the silencer chamber 8 in pairs.

[0036] The inner walls of the first noise reduction closed shell 4 and the second noise reduction closed shell 5 are both fixedly connected with a sound absorbing panel 7 .

[0039] The following is a detailed description of the working principle of the noise reduction electric cylinder.

[0040] like Figure 1-5 As shown, when in use, when it is necessary to remove the first noise reduction sealing shell 4 and the second noise reduction sealing shell 5 from the electric cylinder body 1, the staff will remove the bolts installed on the connecting plate 6, and remove them in sequence until the last group of connecting plates 6 are removed, and then remove the bolts on the receiving frame 11, and the first noise reduction sealing shell 4 and the second noise reduction sealing shell 5 can be pulled outward along the end of the receiving frame 11 and removed from the electric cylinder body 1. After that, the first noise reduction sealing shell 4 and the second noise reduction sealing shell 5 can be maintained or replaced without removing the electric cylinder body 1 from the equipment. Conversely, the first noise reduction sealing shell 4 and the second noise reduction sealing shell 5 can be re-installed on the outer wall of the electric cylinder body 1 to perform noise reduction work.

[0041] During the use of the electric cylinder body 1, the noise generated by it will be dispersed by the arrangement structure of the silencer fins 9 during the process of spreading outwards. At the same time, when the vibration is transmitted to the silencer fins 9, the silencer fins 9 are vibrated by force. At this time, the auxiliary spring 13 will use its deformation elastic force to offset the vibration of the silencer fins 9, thereby enabling the silencer fins 9 to absorb the noise, and at the same time cooperate with the sound-absorbing panel 7 to further enhance the noise reduction effect of the device.

[0042] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
