DETAILED DESCRIPTION

[0025] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0026] According to an embodiment of this utility model, a vibration reduction structure is provided. Please refer to [link / reference]. Figures 1 to 6 The vibration damping structure includes: a support assembly 1; a mounting assembly 2; the mounting assembly 2 is connected to the support assembly 1, and the support assembly 1 and the mounting assembly 2 are movably disposed relative to each other; a buffer cylinder 3; one end of the buffer cylinder 3 is connected to the mounting assembly 2, and the other end of the buffer cylinder 3 is connected to the support assembly 1; the two ends of the buffer cylinder 3 are movably disposed relative to each other; when the support assembly 1 and the mounting assembly 2 move relative to each other, the buffer cylinder 3 compresses the fluid inside the buffer cylinder 3; and a roller assembly; the roller assembly includes roller components, and the roller components are rotatably disposed.

[0027] With the above configuration, the vibration damping structure has better buffering performance compared to existing technologies.

[0028] The hydraulic oil in the buffer cylinder 3 can automatically adjust the damping force according to the magnitude and frequency of the impact. The vibration damping structure also has a better damping effect. When the piston rod 32 of the buffer cylinder 3 reciprocates within the cylinder 31, the hydraulic oil flows through small holes or gaps, generating viscous friction. This converts the kinetic energy of the vibration into heat energy, dissipating it more effectively and quickly calming the vibration, thus preventing aftershocks or secondary vibrations that may occur after damping. The vibration damping structure also has the advantage of high adjustability. The damping characteristics of the buffer cylinder 3 can be easily adjusted by changing the size of the throttling orifice within the buffer cylinder 3, the viscosity of the hydraulic oil, or by using electronically controlled hydraulic valves, to adapt to different working conditions and usage requirements.

[0029] In the vibration reduction structure of this embodiment, see... Figure 1 and Figure 2The two buffering cylinder bodies 3 are arranged at intervals, and the two buffering cylinder bodies 3 are arranged on both sides of the speed reducer 42. The two buffering cylinder bodies 3 have the following advantages compared with one buffering cylinder body 3: stronger buffering capacity, buffering pressure of the two buffering cylinder bodies 3 is dispersed to the two buffering cylinder bodies 3, and the dispersion effect of the buffering cylinder bodies 3 on pressure is more effective, the pressure borne by each buffering cylinder body 3 is relatively small, the high-pressure and large-impact force situation can be better coped with, and the risk of overload of a single buffering cylinder body 3 is reduced. The reliability is higher, when one buffering cylinder body 3 fails, the other buffering cylinder body 3 can be used as a backup to continue to provide a certain buffering effect, and the reliability and safety of the system are increased. The two buffering cylinder bodies 3 share the work load, the working strength of each buffering cylinder body 3 is relatively low, the probability of wear and failure is also reduced, thereby the frequency of maintenance and replacement is reduced, and the service life of the equipment is improved.

[0030] In the damping structure of the embodiment, referring to Figure 6 The mounting assembly 2 comprises a first mounting plate 21 and a second mounting plate 22, the first mounting plate 21 is connected with the second mounting plate 22, and the first mounting plate is attached to a part of the second mounting plate. The second mounting plate 22 is provided with a first connecting opening 58 for the speed reducer 42 to pass through, the first connecting opening 58 is located between the two buffering cylinder bodies 3, and a part of the speed reducer 42 passes through the second mounting plate 22 and is connected with the second mounting plate 22 through the first connecting opening 58, so that the mounting of the damping structure is more compact and reasonable, and the space utilization rate is improved. The first mounting plate is provided with a groove 57 recessed in the first mounting plate 21. The speed reducer 42 can be clamped in the groove 57, so that the connection between the mounting assembly 2 and the speed reducer 42 is more firm.

[0031] In the damping structure of the embodiment, referring to Figure 1 and Figure 4 The buffering cylinder body 3 comprises a cylinder barrel 31 and a piston rod 32, the support assembly 1 is rotatably connected with the cylinder barrel 31 of the buffering cylinder body 3, and the mounting assembly 2 is rotatably connected with the piston rod 32 of the buffering cylinder body 3.

[0032] With the above arrangement, adaptability can be enhanced. In some complex mechanical movements, the working state and force condition will change constantly. The sliding arrangement of the buffer cylinder body 3 at both ends can better adapt to the movement requirements under different working conditions. It can also disperse the acting force. When the buffer cylinder body 3 is working, the force transmission can cause stress concentration at the fixed point. The sliding arrangement of the buffer cylinder body 3 at both ends can make the force more evenly distributed during sliding, reduce local stress, and prolong the service life of the buffer cylinder body 3 and related components. It also improves the flexibility of movement. The sliding arrangement enables the buffer cylinder body 3 to make multidirectional fine adjustments within a certain range during work, which not only realizes linear movement but also to some extent adapts to complex movements such as angle changes, increasing the flexibility and diversity of the movement of the damping structure. Reduces friction loss: compared with fixed connection, the sliding connection of the buffer cylinder body 3 is more advantageous in relative movement, which can effectively reduce friction loss, reduce energy loss, improve system efficiency, and also reduce heat generated by friction, which is conducive to heat dissipation and stable operation of the damping structure.

[0033] In the damping structure of the present embodiment, referring to Figure 2 and Figure 3 , the support assembly 1 includes a first support plate 11 and a second support plate 12; the buffer cylinder body 3 includes a cylinder barrel 31 and a piston rod 32; the cylinder barrel 31 is connected with the first support plate 11; the first support plate 11 is connected with the second support plate 12; a sliding block 71 is arranged on the second support plate 12; a guide rail 72 is arranged on the mounting assembly 2; the sliding block 71 is in sliding connection with the guide rail 72; the mounting assembly 2 is connected with the piston rod 32.

[0034] With the above arrangement, the support assembly 1 is movable relative to the mounting assembly 2 through the sliding block 71 and the guide rail 72. The movable support assembly 1 is connected with the movable cylinder barrel 31, and the fixed mounting assembly 2 is connected with the fixed piston rod 32. When the damping structure is working, the support assembly 1 and the cylinder barrel move relative to the mounting assembly 2 and the piston rod 32 to achieve the effect of damping.

[0035] In the damping structure of the present embodiment, referring to Figure 3 , the sliding block 71 on the second support plate 12 is at least two, which can increase the carrying weight. The at least two sliding blocks 71 share the load and can withstand greater weight, without affecting the machining precision or damaging the equipment due to excessive load. It can also balance the load distribution to avoid excessive wear or deformation of a single sliding block 71 due to concentrated stress, prolonging the service life of the guide rail and the sliding block. The at least two sliding blocks 71 are arranged at intervals on the guide rail 72, and the at least two sliding blocks 71 are in sliding connection with the guide rail.

[0036] In the damping structure of the embodiment, referring to Figure 4 and Figure 5 , the first support plate 11 is provided with a first connecting seat 111; the first connecting seat 111 comprises a first connecting plate 1111 and a second connecting plate 1112; the first connecting plate 1111 is provided with a first connecting hole 51, and the second connecting plate 1112 is provided with a second connecting hole 52; the cylinder barrel 31 is provided with a first connecting block 311 between the first connecting plate 1111 and the second connecting plate 1112; the first connecting block 311 is provided with a fifth connecting hole 55; the damping structure comprises a first connecting piece 61; the first connecting piece 61 is arranged in the first connecting hole 51, the second connecting hole 52 and the fifth connecting hole 55.

[0037] With the above arrangement, the cylinder barrel 31 can be arranged in sliding connection with the first connecting block 311 in the first connecting seat 111, so that the buffering effect can be optimized. In some complex working environments, the damping structure may appear to be inclined or swing at different angles. The sliding of the upper end of the buffer cylinder body 3 can adjust the buffer cylinder body 3 within a certain range according to the change of the angle of the damping structure, so that the damping performance is always good, and the buffering effect can be reliably played under various working conditions.

[0038] In the damping structure of the embodiment, referring to Figure 4 and Figure 6 , the mounting assembly 2 is provided with a second connecting seat 211; the second connecting seat 211 comprises a third connecting plate 2111 and a fourth connecting plate 2112; the third connecting plate 2111 is provided with a third connecting hole 53, and the fourth connecting plate 2112 is provided with a fourth connecting hole 54; the piston rod 32 is provided with a second connecting block 321 between the third connecting plate 2111 and the fourth connecting plate 2112; the second connecting block 321 is provided with a sixth connecting hole 56; the damping structure comprises a second connecting piece 62; the second connecting piece 62 is arranged in the third connecting hole 53, the fourth connecting hole 54 and the sixth connecting hole 56.

[0039] With the above arrangement, the piston rod 32 can be arranged in sliding connection between the second connecting block 321 and the second connecting seat 211, so as to protect the basic structure: when the buffer cylinder 3 is working, the sliding of the lower end of the buffer cylinder 3 can reduce the reaction force and vibration transmission to the damping structure. Through the sliding buffer, part of the impact energy can be converted into the energy of relative motion, reducing the risk of damage to the damping structure and prolonging the service life of the damping structure. The sliding of the lower end of the buffer cylinder 3 helps to maintain the vertical posture of the buffer cylinder 3 during working, ensures that the direction of the buffer force always coincides with the impact direction, improves the stability and reliability of the buffer effect, and avoids the decline of the buffer performance due to the inclination or deviation of the buffer cylinder 3.
