DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0037] In order to make the purpose, technical solutions and advantages of the implementation methods of this application clearer, the technical solutions in the implementation methods of this application will be clearly and completely described below in conjunction with the drawings in the implementation methods of this application. Obviously, the described implementation methods are part of the implementation methods of this application, not all of the implementation methods. Based on the implementation methods in this application, all other implementation methods obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0038] like Figure 1-Figure 14 As shown, according to an embodiment of the present application, a vibration suppression device for optical prism production is used on processing equipment used in the production process of optical prisms to suppress the vibration generated by the processing equipment. The specific installation position and installation method are not difficult to be thought of by relevant technical personnel in the field, and are not described in detail in the specific embodiments of the present application.

[0039] Embodiment 1, as Figure 1-Figure 3 As shown, a vibration suppression device for producing optical prisms according to an embodiment of the present application includes a suppression cylinder 1 , a suppression mechanism 2 and an internal energy consumption component 3 .

[0040] The suppression cylinder 1 is divided into a fixed end and a telescopic end, and the telescopic end is sealed and slidably inserted into the fixed end, so that the suppression cylinder 1 itself has an axial telescopic function.

[0041] like Figure 2 and Figure 3 As shown, the suppression mechanism 2 includes an active piston assembly 21, a passive piston assembly 22 and an auxiliary piston assembly 23. The active piston assembly 21 is sealed and slides in the suppression cylinder 1, and the active piston assembly 21 is fixed to the telescopic end of the suppression cylinder 1. The passive piston assembly 22 is sealed and slides in the suppression cylinder 1. The auxiliary piston assembly 23 is arranged in the suppression cylinder 1, and the passive piston assembly 22 is located between the active piston assembly 21 and the auxiliary piston assembly 23; compressible gas is filled between the passive piston assembly 22 and the auxiliary piston assembly 23, and hydraulic oil is filled on the side of the passive piston assembly 22 away from the auxiliary piston assembly 23.

[0042] Among them, a channel for the circulation of hydraulic oil is axially arranged in the active piston assembly 21. The channel is used to connect the hydraulic oil on both sides of the active piston assembly 21, and when the active piston assembly 21 undergoes axial displacement, the hydraulic oil on both sides can move. The resistance encountered by the hydraulic oil in the channel during the flow process can suppress vibration to a certain extent.

[0043] Axially and radially communicating passages are symmetrically arranged at both ends of the passive piston assembly 22, and the passages at both ends are not communicated with each other to avoid communication between the hydraulic oil and the compressible gas.

[0044] An end of the auxiliary piston assembly 23 facing the passive piston assembly 22 is provided with axially and radially communicating passages, and the pressure generated by the volume change of the compressible gas is used to enhance the sealing performance of the auxiliary piston assembly 23.

[0045] The internal energy dissipation component 3 is rotatably disposed in the active piston component 21 and rotates under the force exerted by the flow of hydraulic oil, thereby further consuming the kinetic energy generated by the hydraulic oil during the flow process, which will further suppress the vibration.

[0046] In addition, a vibration suppression device for optical prism production according to an embodiment of the present application also has the following additional technical features:

[0047] like Figure 1-Figure 3 As shown, the suppression cylinder 1 includes: a cylinder body 11 and a movable rod 12 . The cylinder body 11 is the fixed end of the suppression cylinder 1 ; the movable rod 12 is the movable end of the suppression cylinder 1 , and the movable rod 12 is sealed and slidably plugged into the cylinder body 11 .

[0048] The cylinder body 11 and the movable rod 12 are respectively fixed with a mounting seat 13 and a mounting block 14 to facilitate the installation and fixation of the cylinder 1 on the production equipment.

[0049] like Figure 2-Figure 5 As shown, the active piston assembly 21 includes: an active piston ring 211 and two active rubber rings 212. The active piston ring 211 is fixedly sleeved on the movable end of the suppression cylinder 1. A detachable fixing method is preferred here to facilitate the installation or removal of the active piston assembly 21. The active piston ring 211 is centrally symmetrically arranged; the two active rubber rings 212 are symmetrically sealed sleeved on the circumferential side of the active piston ring 211, and slideably cooperate with the internal seal of the fixed end of the suppression cylinder 1.

[0050] Among them, Figure 4 and Figure 5 As shown, the channel for hydraulic oil circulation arranged along the axial direction on the active piston assembly 21 includes: two first annular grooves 213 , a first cavity 214 , a plurality of first liquid inlet through holes 215 and a plurality of first liquid outlet through holes 216 .

[0051] The two first annular grooves 213 are symmetrically arranged on the circumference of the active piston ring 211 and correspond to the two active rubber rings 212 , so that the two active rubber rings 212 are embedded in the active piston ring 211 .

[0052] The first cavity 214 is disposed inside the active piston ring 211 .

[0053] The plurality of first liquid inlet through holes 215 are symmetrically arranged at both ends of the active piston ring 211 and are connected to the first cavity 214 . The plurality of first liquid inlet through holes 215 are evenly arranged in the circumferential direction at both ends of the active piston ring 211 .

[0054] The plurality of first liquid outlet holes 216 are symmetrically arranged in the two first annular grooves 213 , and the plurality of first liquid outlet holes 216 are radially arranged and connected to the first cavity 214 , and the plurality of first liquid outlet holes 216 are circumferentially uniformly arranged in the two first annular grooves 213 .

[0055] It can be understood that, through the connection between the symmetrically arranged multiple first liquid inlet holes 215 and the first cavity 214, the hydraulic oil is connected on both sides of the active piston assembly 21. When the active piston assembly 21 undergoes axial displacement, the hydraulic oil on both sides thereof will flow through the active piston assembly 21, and when passing through the multiple first liquid inlet holes 215, it will encounter resistance due to the narrowing of the channel, and this resistance will suppress the vibration of the equipment. Secondly, through the connection between the multiple first liquid outlet holes 216 and the first cavity 214, the hydraulic oil will generate outward radial pressure when passing through the active piston assembly 21, exerting an outward thrust on the two active rubber rings 212, thereby enhancing the sealing performance between the two active rubber rings 212 and the inner wall of the suppression cylinder 1.

[0056] like Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, the passive piston assembly 22 includes: a first passive piston ring 221 , a second passive piston ring 222 , a first passive rubber ring 223 and a second passive rubber ring 224 .

[0057] A cavity is provided in the first passive piston ring 221 .

[0058] The second passive piston ring 222 and the first passive piston ring 221 are symmetrically arranged and fixedly connected. It should be noted that the second passive piston ring 222 and the first passive piston ring 221 have completely the same structure and size.

[0059] The first passive rubber ring 223 is sealingly sleeved on the circumference of the first passive piston ring 221 , and the second passive rubber ring 224 is sealingly sleeved on the circumference of the second passive piston ring 222 .

[0060] Furthermore, the axially and radially communicating channels symmetrically arranged at both ends of the passive piston assembly 22 include: an axial through hole 225 and a plurality of passive connecting blocks 226. The axial through hole 225 is symmetrically arranged at one end of the first passive piston ring 221 and the second passive piston ring 222 that are away from each other, and is connected to the cavity inside the first passive piston ring 221 and the second passive piston ring 222, thereby forming an axially and radially communicating channel.

[0061] The plurality of passive connection blocks 226 are symmetrically arranged in the cavity in the first passive piston ring 221 and the cavity in the second passive piston ring 222 , and the plurality of passive connection blocks 226 are circumferentially spaced in the cavity so that the radial channel is not blocked by the passive connection blocks 226 .

[0062] The first passive rubber ring 223 and the second passive rubber ring 224 respectively cover the plurality of passive connection blocks 226 on both sides.

[0063] It can be seen that the two symmetrical and non-interconnected axial and radial channels symmetrically arranged at both ends of the passive piston assembly 22 prevent the hydraulic oil and compressible gas on both sides from being connected to each other, thereby affecting the overall suppression capability of the suppression cylinder 1. Among them, the axial and radial channels located on the hydraulic oil side can utilize the pressure generated when the hydraulic oil is squeezed to enhance the sealing performance of the first passive rubber ring 223. Similarly, the axial and radial channels located on the compressible gas side can utilize the pressure formed during the change of gas volume to enhance the sealing performance of the second passive rubber ring 224.

[0064] like Figure 2 , Figure 3 , Figure 8 and Fig. 9As shown, the auxiliary piston assembly 23 includes: an auxiliary piston ring 231 and an auxiliary rubber ring 232 . The auxiliary piston ring 231 is provided with a cavity; and the auxiliary rubber ring 232 is sealed on the peripheral side of the auxiliary piston ring 231 .

[0065] Among them, the axially and radially communicating channels arranged at one end of the auxiliary piston assembly 23 toward the passive piston assembly 22 include: a plurality of second liquid inlet holes 233 and a plurality of auxiliary connecting blocks 234, the plurality of second liquid inlet holes 233 are arranged circumferentially and connected to the cavity arranged in the auxiliary piston ring 231; the plurality of auxiliary connecting blocks 234 are arranged axially at intervals in the cavity; the auxiliary rubber ring 232 covers the plurality of auxiliary connecting blocks 234.

[0066] Similarly, the pressure generated by the change in gas volume can be used to enhance the sealing performance of the auxiliary rubber ring 232 .

[0067] like Figure 3-Figure 5 As shown, the internal energy dissipation component 3 is rotatably sleeved on the inner arc surface of the first cavity 214, and the outer diameter of the internal energy dissipation component 3 is smaller than the diameter of the outer arc surface of the first cavity 214. It can be understood that there is no contact between the outer side of the internal energy dissipation component 3 and the outer arc surface of the first cavity 214.

[0068] Furthermore, the internal energy dissipation component 3 includes: an cambered ring 31 and a plurality of spoiler blades 32. The cambered ring 31 is rotatably sleeved on the inner cambered surface of the first cavity 214. The cambered ring 31 is symmetrically arranged in the axial direction, and both ends of the cambered ring 31 are arranged with cambered surfaces concave inwardly. The cambered ring 31 is arranged to shrink from the inside to the outside in the radial direction, which plays a guiding role for the hydraulic oil passing through the active piston assembly 21, and changes the size of its flow channel in the active piston assembly 21 to enhance the resistance it encounters; the plurality of spoiler blades 32 are symmetrically arranged on both sides of the cambered ring 31 in the axial direction, and the spoiler blades 32 are arranged in an inclined arc shape. The arrangement of the spoiler blades 32 enables the hydraulic oil to apply power to the spoiler blades 32 when passing through the inside of the active piston assembly 21, forcing the internal energy dissipation component 3 to rotate in the first cavity 214, thereby consuming energy by rotation.

[0069] The following describes the use process of a vibration suppression device for producing an optical prism according to an embodiment of the present application with reference to the accompanying drawings:

[0070] When in use, the suppression cylinder 1 is installed on the production equipment, and the reciprocating axial displacement of the movable rod 12 in the cylinder body 11 is used to suppress the vibration of the equipment. Specifically, when the movable rod 12 drives the active piston assembly 21 to make an inward axial displacement in the cylinder body 11, the hydraulic oil between the active piston assembly 21 and the passive piston assembly 22 is squeezed. In order to maintain the pressure conservation in the cylinder body 11, the hydraulic oil will enter the first cavity 214 from the first liquid inlet through hole 215 on the right, and flow out to the left side of the active piston assembly 21 through the first liquid inlet through hole 215 on the left. In this process, due to the shrinkage of the hydraulic oil flow channel, resistance will be generated and the active piston assembly 21 will be affected. The vibration force on the moving rod 12 is suppressed. Secondly, the hydraulic oil in the first cavity 214 maintains a dynamic form, so it will apply a tangential force to the spoiler blades 32 on the internal energy dissipation component 3, causing the internal energy dissipation component 3 to rotate in the first cavity 214. In this way, the consumption of kinetic energy will further enhance the effect of vibration suppression. The gradual change design (arc surface) of the arc surface ring 31 further changes the flow channel of the hydraulic oil in the first cavity 214, which not only plays a certain resistance, but also plays a certain guiding role for the hydraulic oil, so that the pressure change originally exerts an outward pressure on the two active rubber rings 212 through the first liquid outlet through hole 216. Under the guiding effect of the arc surface ring 31, The hydraulic oil further exerts a certain impact on the two active rubber rings 212, and then further improves the sealing strength between the two active rubber rings 212 and the inner wall of the cylinder body 11. At the same time, because the hydraulic oil is subjected to resistance in the process of passing through the active piston assembly 21, it will exert a certain pressure on the passive piston assembly 22, that is, forcing the passive piston assembly 22 to move toward the auxiliary piston assembly 23 and compress the compressible gas in between. After the compressed gas is compressed, the pressure value inside it increases, which will simultaneously exert an axial reaction force on the passive piston assembly 22, further offsetting and suppressing the pressure exerted by the vibration transmitted by the hydraulic oil. In this process , the side of the passive piston assembly 22 facing the hydraulic oil, the hydraulic oil will flow toward the first passive rubber ring 223 through the axial through hole 225, and exert an outward radial force on the first passive rubber ring 223, thereby enhancing the sealing strength between the first passive rubber ring 223 and the inner wall of the cylinder body 11. Similarly, the side of the passive piston assembly 22 facing the compressible gas, the change in gas pressure will also pass through the axial through hole 225 to exert an outward radial force on the second passive rubber ring 224, thereby enhancing the sealing performance between the second passive rubber ring 224 and the inner wall of the cylinder body 11. Similarly, the auxiliary rubber ring 232 on the auxiliary piston assembly 23 is also affected by the change in gas pressure, thereby enhancing the sealing strength between itself and the inner wall of the cylinder body 11.On the contrary, when the active rod 12 drives the active piston assembly 21 to move axially outward along the cylinder body 11, the hydraulic oil on the left side of the active piston assembly 21 will be squeezed to the right side of the active piston assembly 21. The hydraulic oil will also encounter resistance in the process of passing through the active piston assembly 21 and drive the internal energy-consuming assembly 3 to rotate to consume kinetic energy, and enhance the sealing effect of the active rubber ring 212. During this period, the volume of the compressible gas between the passive piston assembly 22 and the auxiliary piston assembly 23 increases, that is, the passive piston assembly 22 may be compressed due to the circulation of hydraulic oil. The speed is not enough and is forced to move axially away from the auxiliary piston assembly 23. At this time, the pressure value of the compressed gas becomes smaller, forming a certain negative pressure, and forming a certain suction force on the passive piston assembly 22. The two phases (the resistance generated when the left hydraulic oil flows, and the suction force formed by the compressible gas) will form resistance and attenuation to the original outward axial displacement of the active rod 12. In this way, the active piston assembly 21 will be driven by the active rod 12 to move axially in the cylinder body 11, which will suppress the vibration of the equipment, thereby improving the accuracy of the equipment and then improving the processing accuracy of the optical prism. ;

[0071] Embodiment 2. In the related art, in a vibration suppression device for producing optical prisms, the size of the first liquid inlet hole 215 on the active piston assembly 21 is fixed, so the resistance value formed by the hydraulic oil during the flow process is fixed. Although an internal energy-consuming assembly 3 that can be driven and rotated by the hydraulic oil is arranged inside, once the vibration force is large or too frequent, the resistance formed by the hydraulic oil still has a weak effect on suppressing the vibration, and the hysteresis formed when the hydraulic oil shuttles back and forth on the active piston assembly 21 (for example, after being subjected to a certain force, a certain amount of hydraulic oil has not completely flowed to the other side of the active piston 21, and is subjected to a reverse force, at this time the hydraulic oil flows in the opposite direction, and at this time the side to which the hydraulic oil needs to flow still has hydraulic oil that will flow to the other side in the future and this state is described as the hysteresis phenomenon of the hydraulic oil in this application) is weak, and the vibration suppression ability transmitted by the equipment is weak.

[0072] According to some embodiments of the present application, Figure 3 , Figure 10-13 As shown, two groups of end energy dissipation mechanisms 4 are symmetrically arranged on both sides of the active piston assembly 21, the two groups of end energy dissipation mechanisms 4 are elastically connected to the ends of the active piston assembly 21, and the end energy dissipation mechanisms 4 are slidably connected to the internal sealing of the fixed end of the suppression cylinder 1, and the end energy dissipation mechanisms 4 are axially arranged with channels for the hydraulic oil to enter and exit, so that the hydraulic oil can continue to be connected on both sides of the active piston assembly 21.

[0073] The end energy dissipation mechanism 4 includes an energy dissipation baffle 41 , a tension spring 42 and a power member 43 .

[0074] It should be noted that the energy dissipation baffle 41 is sealingly slidable on the suppression cylinder 1 , and is coaxial with the movable rod 12 but does not contact it.

[0075] Two ends of the tension spring 42 are respectively fixed to the end of the active piston assembly 21 and the energy dissipation baffle 41 , so as to reset the energy dissipation baffle 41 .

[0076] The power member 43 is sealingly rotatably connected to the energy dissipation baffle 41 and is coaxially arranged with the energy dissipation baffle 41 . It should be noted that the power member 43 is sealingly rotatably sleeved on the movable rod 12 .

[0077] Specifically, the power component 43 includes: a guide bottom plate 431 , a guide top plate 432 and a plurality of guide blades 433 .

[0078] Among them, Figure 11-13 As shown, a through hole is provided at the axis center of the guide bottom plate 431 , and the side thereof facing the energy dissipation baffle 41 is arranged in an arc shape, and the cross section thereof is gradually contracted along the radial direction from the inside to the outside.

[0079] The guide top plate 432 is arranged in an annular shape, and a through hole is arranged at its axis center. The inner diameter of the through hole is larger than the through hole at the axis center of the guide bottom plate 431. The guide top plate 432 is rotatably embedded in the energy dissipation baffle 41, so that a rotational connection is formed between the entire power part 43 and the energy dissipation baffle 41, and synchronous axial displacement in the same direction can occur.

[0080] A plurality of guide blades 433 are evenly arranged circumferentially between the guide bottom plate 431 and the guide top plate 432, and are respectively fixed to the guide bottom plate 431 and the guide top plate 432. The guide blades 433 are arranged in an arc shape, so as to utilize the hydraulic oil to exert force on the guide blades 433 during the flow process and drive the power part 43 to rotate, thereby further playing a role in power consumption.

[0081] Furthermore, the axially arranged channel for the hydraulic oil to enter and exit the end energy dissipation mechanism 4 includes: a channel formed by multiple guide blades 433 between the guide bottom plate 431 and the guide top plate 432, and the overlap between the two through holes on the guide bottom plate 431 and the guide top plate 432.

[0082] It is understandable that when the hydraulic oil flows on both sides of the end energy dissipation mechanism 4 , it can and can only pass through the power member 43 , and then flow to the active piston assembly 21 or to the side of the energy dissipation baffle 41 away from the active piston assembly 21 .

[0083] In the specific embodiment of the present application, the example of the movable rod 12 driving the active piston assembly 21 to axially displace into the cylinder body 11 is used for explanation. At this time, the hydraulic oil on the right side will flow to the left side under the extrusion effect. In this process, the hydraulic oil on the right side will exert an axial extrusion force on the energy-consuming baffle 41 on the right side, and flow into the channel at the axis of the power member 43 on this side, and finally flow out from the radial direction of the power member 43. During the flow process in the power member 43, a tangential force will be exerted on the guide vane 433 to drive the power member 43 to move in the radial direction. The power piece 43 rotates, consuming kinetic energy to a certain extent, and then the hydraulic oil shuttles through the active piston assembly 21, exerts a thrust on the energy-consuming baffle 41 on the left, forcing it to move away from the active piston assembly 21 and stretching the tension spring 42. At this time, the tension spring 42 generates a restoring tension, which consumes the potential energy of the hydraulic oil. Then the hydraulic oil enters the power piece 43 on the left from the radial direction, and drives the left power piece 43 to rotate, further consuming kinetic energy, and then flows out from the axial direction of the left power piece 43. Conversely, when the movable rod 12 drives When the active piston assembly 21 is axially displaced out of the cylinder body 11, the hydraulic oil and the energy-absorbing baffles 41 and the tension springs 42 on both sides undergo the above-mentioned reverse movement, and the power member 43 still rotates. Due to the symmetrical arrangement of the energy-absorbing baffles 41, the tension springs 42 and the power member 43, it can be understood that the smoothness of the flow of the hydraulic oil on both sides of the active piston assembly 21 is further reduced, and the damping phenomenon generated is stronger. During normal use, since vibration is a reciprocating displacement phenomenon, the hydraulic oil will reciprocate on both sides of the active piston assembly 21 under the vibration of the equipment. Hindered by the symmetrically arranged end energy-absorbing mechanisms 4, the hysteresis phenomenon of the hydraulic oil on both sides of the active piston assembly 21 will be aggravated, which will have a good inhibitory effect on the kinetic energy generated in the vibration phenomenon, effectively reduce the vibration phenomenon of the equipment, and also reduce the force on the internal energy-absorbing component 3 to rotate faster, reduce the heat energy generated by the hydraulic oil in the process of shuttling back and forth, and to a certain extent share the force of the internal energy-absorbing component 3, thereby extending the life of the three rotating parts inside the suppression cylinder 1.

[0084] Embodiment 3. In the related art, although the vibration suppression device for producing optical prisms has three rotating parts designed inside to consume the kinetic energy of the hydraulic oil, the energy consumption generated has certain limitations due to the fixed size of the structure. There will always be a time when the kinetic energy generated by the vibration exceeds the suppression capacity of the suppression cylinder 1 in the present application. In this way, the load of the three rotating parts will be increased, causing their rotation speed to increase, resulting in an increase in the temperature rise rate of the hydraulic oil in the suppression cylinder 1. After the entire suppression cylinder 1 is overloaded, it not only reduces its own vibration suppression effect, but also reduces the service life of its internal force-bearing parts.

[0085] According to some embodiments of the present application, Figure 1-Figure 3, Fig. 9 and Fig.14 As shown, an adjusting mechanism 5 is coaxially arranged on the auxiliary piston assembly 23, and the adjusting mechanism 5 has a displacement end and a rotation end. The displacement end of the adjusting mechanism 5 is fixedly plugged into the auxiliary piston assembly 23, and the rotation end of the adjusting mechanism 5 extends out of the suppression cylinder 1 and is sealed and rotatably connected to the suppression cylinder 1. The displacement end of the adjusting mechanism 5 and the rotation end of the adjusting mechanism 5 are threadedly matched, and the displacement end of the adjusting mechanism 5 and the end of the suppression cylinder 1 are axially plugged into each other.

[0086] Specifically, the rotating end of the adjustment mechanism 5 includes a rotating column 51 , which is sealed and plugged into the end of the suppression cylinder 1 , and an end of the rotating column 51 located in the suppression cylinder 1 is provided with an external threaded portion 511 .

[0087] The displacement end of the adjustment mechanism 5 includes: a movable ring 52 and a positioning plate 53. The movable ring 52 is fixedly inserted in the auxiliary piston assembly 23, so that the movable ring 52 and the auxiliary piston assembly 23 are integrated and can maintain synchronous and unidirectional axial displacement. The positioning plate 53 is fixedly sleeved on the movable ring 52, so that the positioning plate 53 and the movable ring 52 are also integrated.

[0088] Furthermore, the movable ring 52 has one end facing the rotating column 51 , and an internal threaded portion 521 matching the external threaded portion 511 is provided therein. A positioning rod 531 is evenly fixed circumferentially on the positioning plate 53 , and the positioning rod 531 is slidably inserted into the end of the suppression cylinder 1 .

[0089] It can be understood that, through the plug-in relationship between the positioning rod 531 and the end of the suppression cylinder 1, the positioning plate 53 can and can only undergo axial displacement in the cylinder body 11, but cannot rotate. In this way, the movable ring 52 can and can only undergo axial displacement in the cylinder body 11, but cannot rotate. Therefore, when the rotating column 51 rotates on the cylinder body 11, the movable ring 52 will undergo axial displacement through the matching external threaded portion 511 and the internal threaded portion 521.

[0090] Therefore, when it is used specifically, the rotation of the rotating column 51 can drive the movable ring 52 to undergo axial displacement changes, and then drive the auxiliary piston assembly 23 to undergo synchronous axial displacement in the same direction. It can be understood that when the capacity of the hydraulic oil remains unchanged, its compression amount can be ignored. Therefore, when there is no other external force, the position of the passive piston assembly 22 in the cylinder body 11 remains unchanged, while the auxiliary piston assembly 23 undergoes displacement changes under the action of the movable ring 52, which will change the volume of the compressed gas between the passive piston assembly 22 and the auxiliary piston assembly 23. It can be further understood that when the volume of the compressible gas expands, the pressure value therein will become smaller, that is, at this time The reaction force in the direction of the compressible gas received by the passive piston assembly 22 is reduced, the range of kinetic energy generated by the bearing vibration is reduced, and the vibration suppression effect is reduced to a certain extent. On the contrary, when the volume of the compressible gas becomes smaller, the reaction force in the direction of the compressible gas received by the passive piston assembly 22 is increased, and it will be able to bear the kinetic energy generated by a larger range of vibrations, and the vibration suppression effect is improved to a certain extent. In this way, through the rotation of the rotating column 51, the suppression cylinder 1 in the present application will have the adjustment of the bearing range. Within the effective range of vibration suppression, the load-bearing parts in the suppression cylinder 1 can be protected by correcting the bearing range, thereby improving the service life of the suppression cylinder 1 and simultaneously ensuring its vibration suppression capability.

[0091] Embodiment 4: Of course, the suppression cylinder 1 in the present application can also be set as multiple ones on the processing equipment, and the suppression effect on the vibration of the equipment can be further improved through various combinations of multiple suppression cylinders 1 connected in parallel and in series.

[0092] It should be noted that the specific models and specifications of the active rubber ring 212, the first passive rubber ring 223, the second passive rubber ring 224 and the auxiliary rubber ring 232 need to be selected and determined according to the actual specifications of the device, etc. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0093] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
