Description

Technical Field

[0001] This invention relates to the field of buffer support equipment technology, and in particular to an adjustable multi-directional buffer elastic support equipment. Background Technology

[0002] In modern precision equipment manufacturing, industrial equipment installation, and special transportation conditions, support devices not only need to provide stable vertical load-bearing capacity, but also need to have good vibration damping, impact buffering, and installation self-adaptation capabilities. Continuous micro-vibrations generated during equipment operation, instantaneous impacts during start-up and shutdown, combined loads caused by transportation bumps, as well as issues such as installation surface tilt, assembly gap deviations, and eccentric loading, can easily lead to equipment precision drift, loosening of connection structures, and fatigue damage to components, seriously affecting the operational stability and service life of the equipment. Therefore, high-performance, adjustable, and multi-directional self-adaptive elastic support structures are core foundational components that ensure the long-term high-precision and high-reliability operation of precision equipment.

[0003] Currently, most existing elastic supports and vibration damping bearing structures use a single rubber pad, a single spring for vertical vibration damping, or a fixed cylinder buffer structure. Their functional design is relatively simple, with limited adjustment range and a single buffering direction. After long-term use, they are prone to problems such as swaying and loosening, making it difficult to meet the needs of precision equipment or complex working conditions for adaptive and highly stable support. Moreover, traditional supports often mainly deal with vertical loads, and are not adaptable enough to complex multi-directional vibration, impact, or off-center load conditions, which can easily lead to stress concentration or buffer failure. Summary of the Invention

[0004] The purpose of this invention is to provide an adjustable multi-directional buffer elastic support device to solve problems such as limited adjustment range, single buffer direction, and easy swaying and loosening after long-term use, which make it difficult to meet the needs of precision equipment or complex working conditions for adaptive and highly stable support. In addition, traditional supports often mainly deal with vertical loads, and are not adaptable enough to complex multi-directional vibration, impact or off-center load conditions, which can easily lead to stress concentration or buffer failure.

[0005] To achieve the above objectives, the present invention provides an adjustable multi-directional buffer elastic support device, including a base plate and an upper support plate. A first cylinder and a second cylinder are respectively disposed on the surfaces of the base plate and the upper support plate. A bidirectional buffer assembly and a central guide assembly are disposed between the base plate and the upper support plate. The central guide assembly includes a third cylinder and a central elastic guide body. The central elastic guide body is disposed on the side of the third cylinder. Two third cylinders are symmetrically arranged. The bidirectional buffer assembly includes a support rod and a connecting rod. Two sets of the support rod are symmetrically arranged along the center position of the central elastic guide body. A connecting rod is fixedly installed at both ends of the support rod. One end of the two sets of connecting rods is located in the third cylinder, and the other end of the two sets of connecting rods is located in the first cylinder and the second cylinder, respectively. The third cylinder, the first cylinder, and the second cylinder are all filled with elastic buffer pads.

[0006] Preferably, the surface of the upper support plate is further provided with a rectangular height adjustment frame, and the second cylinder is vertically slidably mounted in the height adjustment frame for adjusting the height of the device.

[0007] Preferably, the elastic buffer pad is integrally molded from high-damping polyurethane elastic material, with a hollow interior. Several buffer springs are provided in the hollow part, and the two ends of the buffer springs are bonded and fixed to the inner wall of the hollow cavity of the elastic buffer pad.

[0008] Preferably, the central elastic guide is made of a composite material of highly elastic rubber and glass fiber, which has both flexible vibration reduction and rigid guiding performance. The central elastic guide has an overall long columnar structure and runs longitudinally through the side of the two third cylinders.

[0009] Preferably, the surface of the upper support plate is further provided with a multi-directional adaptive component for compensating for minor displacements when the equipment is installed skewed or subjected to lateral loads. The multi-directional adaptive component includes a ball flange support and a support base plate. The ball flange support is installed on the surface of the upper support plate, and the support base plate is welded to the bottom of the ball flange support. The bottom of the ball flange support has a spherical hinge structure, which slides and fits against the spherical surface of the support base plate, enabling ±15° multi-angle adaptive deflection to adapt to eccentric loads and inclined installation conditions. Locking bolts connect the support base plate and the upper support plate.

[0010] Preferably, the upper support plate has adjustable mounting holes on its surface. These adjustable mounting holes are elongated and are used to fine-tune the position of the ball flange support to accommodate deviations in the equipment mounting hole positions.

[0011] Preferably, a locking washer is provided between the locking bolt and the upper support plate. The inner side of the locking washer is provided with anti-slip teeth with a tooth depth of 0.2mm-0.5mm, which is used to prevent the locking bolt from loosening under long-term vibration.

[0012] Preferably, the height adjustment frame is provided with a height adjustment component for adjusting the height of the equipment. The height adjustment component includes a lead screw and a threaded block. The lead screw is rotatably installed at the bottom of the second cylinder. The threaded block is fixedly installed on the surface of the height adjustment frame. The lead screw and the threaded block are threadedly connected for adjusting the height of the second cylinder. An adjustment bolt is fixedly installed at one end of the lead screw.

[0013] The advantages and positive effects of the adjustable multi-directional buffer elastic support device described in this invention are: 1. This invention uses a symmetrical bidirectional buffer component with a central guide component to simultaneously achieve vertical tension and compression bidirectional buffering, as well as radial and angular multidimensional vibration reduction, solving the defects of traditional support equipment that only provides unidirectional buffering and cannot adapt to lateral impacts and eccentric loads; through the composite structure of elastic buffer pad and built-in buffer spring, it achieves graded buffering, flexible vibration damping for small vibrations and rigid pressure bearing for large impacts, resulting in significant vibration reduction effect.

[0014] 2. This invention achieves high-precision fine-tuning of the support height through a stepless height adjustment structure using a lead screw thread combined with a height adjustment frame for limiting and guiding. It can quickly adapt to non-standard working conditions such as uneven installation surfaces, differences in equipment load, and deviations in assembly height. Precise leveling can be achieved without the need for additional shims, making adjustment convenient and more accurate.

[0015] 3. This invention achieves multi-angle adaptive deflection through the spherical flange support spherical hinge structure, and with the adjustable mounting hole micro-adjustment structure, it can automatically compensate for displacement deviations caused by installation tilt and equipment eccentricity; at the same time, with the anti-slip locking gasket anti-loosening structure, it prevents structural sway, bolt loosening and coaxiality misalignment problems during long-term use, and significantly improves service life.

Furthermore, the terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit the scope of this application.

[0022] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0023] Reference Figures 1-6As shown, the present invention provides a technical solution: an adjustable multi-directional buffer elastic support device, including a base plate 1 and an upper support plate 2. A first cylinder 11 and a second cylinder 22 are respectively provided on the surfaces of the base plate 1 and the upper support plate 2. A bidirectional buffer assembly 3 and a central guide assembly 4 are provided between the base plate 1 and the upper support plate 2. The central guide assembly 4 includes a third cylinder 41 and a central elastic guide body 42. The central elastic guide body 42 is provided on the side of the third cylinder 41, and two third cylinders 41 are symmetrically arranged. The central elastic guide body 42 is made of a high-elasticity rubber and glass fiber composite material, which has both flexible vibration reduction and rigid guiding performance. The central elastic guide body 42 has an overall elongated columnar structure, which longitudinally penetrates the sides of the two third cylinders 41, and is used to achieve radial limiting, anti-swaying and centering guidance.

[0024] Reference Figures 1-6 As shown, the bidirectional buffer assembly 3 includes a support rod 31 and a connecting rod 32. Two sets of support rods 31 are symmetrically arranged along the center position of the central elastic guide body 42. Connecting rods 32 are fixedly installed at both ends of the support rods 31. One end of the two sets of connecting rods 32 is located in the third cylinder 41, and the other end of the two sets of connecting rods 32 is located in the first cylinder 11 and the second cylinder 22, respectively. The third cylinder 41, the first cylinder 11, and the second cylinder 22 are all filled with elastic buffer pads 33. The elastic buffer pads 33 completely cover the insertion ends of the corresponding connecting rods 32, realizing vertical bidirectional tension and compression buffering and radial vibration reduction. Together with the central elastic guide body 42, it realizes multi-directional coupling vibration reduction and avoids equipment vibration sway and stress concentration.

[0025] By using a symmetrical bidirectional buffer assembly 3 and a central guide assembly 4, vertical tension and compression bidirectional buffering, as well as radial and angular multidimensional vibration reduction can be achieved simultaneously, solving the defects of traditional support equipment that only provides unidirectional buffering and cannot adapt to lateral impacts and eccentric loads. Through the composite structure of elastic buffer pad 33 and built-in buffer spring 34, graded buffering is achieved, with flexible vibration damping for small vibrations and rigid pressure bearing for large impacts, resulting in significant vibration reduction effect.

[0026] Reference Figures 1-6 As shown, the elastic buffer pad 33 is integrally molded from high-damping polyurethane elastic material, which has the characteristics of aging resistance, compression deformation resistance and high resilience. The interior is hollow, and several buffer springs 34 are set in the hollow part. The buffer springs 34 are stainless steel compression springs. The two ends of the buffer springs 34 are bonded and fixed to the inner wall of the hollow cavity of the elastic buffer pad 33. The composite structure of the elastic buffer pad 33 and the buffer springs 34 improves the buffer stiffness and the upper limit of the load-bearing capacity, so as to achieve a graded buffering effect of flexible vibration reduction for small vibrations and rigid pressure bearing for large impacts.

[0027] Reference Figures 1-6As shown, the surface of the upper support plate 2 is also provided with a multi-directional adaptive component 5, which is used to compensate for small displacements when the equipment is installed skewed or subjected to lateral loads. The multi-directional adaptive component 5 includes a ball flange support 51 and a support base plate 52. The ball flange support 51 is installed on the surface of the upper support plate 2. The support base plate 52 is welded to the bottom of the ball flange support 51. The bottom of the ball flange support 51 is a spherical hinge structure, which is in close contact with the spherical surface of the support base plate 52 and slides together, which can realize ±15° multi-angle adaptive deflection, adapting to eccentric loads and inclined installation conditions. The support base plate 52 is connected to the upper support plate 2 by a locking bolt 54, which is fastened to the upper support plate 2. The buffer spring 34 is a consumable part. After the ball flange support 51 is disassembled, it is convenient to replace the spring rubber of the elastic support equipment.

[0028] Reference Figures 1-6 As shown, the upper support plate 2 has adjustable mounting holes 53 on its surface. The adjustable mounting holes 53 are elongated holes used to fine-tune the position of the ball flange support 51, adapt to the deviation of the equipment mounting hole position, and improve the overall assembly alignment accuracy and working condition adaptability. A locking washer 55 is also provided between the locking bolt 54 and the upper support plate 2. The inner side of the locking washer 55 is provided with anti-slip teeth with a tooth depth of 0.2mm-0.5mm. After locking, it can form a mechanical self-locking structure, which greatly increases the friction resistance and effectively prevents the locking bolt 54 from loosening or shifting under long-term vibration and impact conditions of the equipment, thereby improving the long-term operational stability of the overall structure.

[0029] The ball flange support 51 achieves multi-angle adaptive deflection through a spherical hinge structure. Combined with the adjustable mounting hole 53 with an elongated hole, it can automatically compensate for displacement deviations caused by installation tilt and equipment eccentricity. At the same time, the anti-slip locking gasket 55 prevents structural swaying, bolt loosening, and coaxiality misalignment during long-term use, thus significantly extending the service life.

[0030] Reference Figures 1-6 As shown, a height adjustment component 6 is provided in the height adjustment frame 21 for adjusting the height of the equipment. A rectangular height adjustment frame 21 is also provided on the surface of the upper support plate 2. The second cylinder 22 is vertically slidably installed in the height adjustment frame 21 for adjusting the height of the device. The height adjustment component 6 includes a lead screw 61 and a threaded block 62. The lead screw 61 is rotatably installed at the bottom of the second cylinder 22. The threaded block 62 is fixedly installed on the surface of the height adjustment frame 21. The lead screw 61 and the threaded block 62 are threadedly connected for adjusting the height of the second cylinder 22. An adjusting bolt 63 is fixedly installed at one end of the lead screw 61. By rotating the adjusting bolt 63, the lead screw 61 is rotated, driving the second cylinder 22 to rise and fall vertically along the height adjustment frame 21, realizing stepless fine adjustment of the support height. The adjustment accuracy can reach 0.5mm, adapting to different load heights and installation leveling requirements.

[0031] The stepless height adjustment structure with screw 61 and height adjustment frame 21 limit guide can achieve high-precision fine adjustment of support height. It can quickly adapt to non-standard working conditions such as uneven installation surface, equipment load difference, and assembly height deviation. It can achieve precise leveling without the need to add extra shims, making adjustment convenient and more accurate.

[0032] Therefore, the adjustable multi-directional buffer elastic support device described in this invention, which uses an upper and lower symmetrical bidirectional buffer component 3 in conjunction with a central guide component 4, can simultaneously achieve vertical tension and compression bidirectional buffering, as well as radial and angular multi-dimensional vibration reduction, solving the defects of traditional support devices that only provide unidirectional buffering and cannot adapt to lateral impacts and eccentric loads; through the composite structure of elastic buffer pad 33 and built-in buffer spring 34, graded buffering is achieved, with flexible vibration damping for small vibrations and rigid pressure bearing for large impacts, resulting in significant vibration reduction effect.

Furthermore, the buffer spring 34 is a consumable part, and the ball flange support 51 can be disassembled to facilitate the replacement of the spring rubber on the elastic support equipment.
