Description

Technical Field

[0001] This utility model relates to the field of vibration isolation platform technology, and more specifically to a self-constrained vibration isolation platform. Background Technology

[0002] With the continuous improvement of information technology in my country's equipment manufacturing industry, various precision instruments are widely used, and their performance reliability and stability have attracted much attention. Many factors affect the performance of various precision instruments, and vibration and shock are among the most important. Vibration and shock can lead to a series of problems such as broken component connections, short circuits, reduced measurement accuracy, and blurred images. Many factors cause vibration, such as fluid disturbances and explosive impacts, which are often unavoidable. Therefore, vibration reduction and isolation measures are extremely necessary. Generally, measures to reduce the impact of vibration and shock mainly involve increasing the rigidity of the instrument itself or implementing vibration reduction and isolation treatments.

[0003] Vibration reduction and isolation treatment generally uses energy dissipation dampers to consume the impact energy that has been transmitted to the protected body, thereby reducing the damage of vibration to the protected body. For example, the multi-degree-of-freedom vibration isolation buffer platform with prior art publication number CN215293435U.

[0004] However, the above-mentioned existing technologies still have the following problems when used: vibration isolation platforms generally use vibration isolators to isolate vibrations. Commonly used vibration isolation platforms do not have restraint devices in the radial direction, and the vibration isolation platform will move excessively, making it impossible to ensure the accurate positioning of the vibration isolation platform, which will affect the vibration isolation effect of the equipment. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides a self-constrained vibration isolation platform to solve the problem that the vibration isolation platform will move excessively, making it impossible to guarantee the accurate positioning of the vibration isolation platform, which in turn affects the vibration isolation effect of the equipment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a self-constrained vibration isolation platform, comprising a base and a vibration isolation plate, wherein a vibration damping mechanism is provided between the base and the vibration isolation plate, and a limiting component is provided on the top of the base, the limiting component comprising a plurality of radial limiting plates evenly distributed on the outer side of the vibration isolation plate, and the top of the base having an installation groove having the same number of mounting slots as the radial limiting plates, the radial limiting plates being inserted into the mounting slots, and the top of the base having a frame-shaped groove, the frame-shaped groove having an installation component fitted inside, the installation component comprising a fixing frame, the fixing frame having a number of insert blocks having the same number as the radial limiting plates inside, each radial limiting plate having an insertion hole processed on its outer wall, the insert block being inserted into the insertion hole.

[0007] In a preferred embodiment, the top of the fixing frame is detachably connected to a top plate equal to the number of inserts, and the bottom of the top plate contacts the top of the inserts for reinforcement.

[0008] In a preferred embodiment, the inner wall of the frame-shaped groove is machined with the same number of slots as the number of inserts, and the slots are connected to the mounting slots. The inserts are inserted into the slots, and the workers can quickly fix the inserts with the help of the slots, thereby improving the installation efficiency of the radial limiting plate.

[0009] In a preferred embodiment, the top of the base is machined with a plurality of fixing slots communicating with the frame-shaped grooves. Each fixing slot can be detachably installed with an electromagnetic lock. The electromagnetic lock is located below the top plate. The inner wall surface of the fixing frame is machined with the same number of locking slots as the electromagnetic locks. The electromagnetic locks are locked with the locking slots to connect the fixing frame and the base together, thereby improving the stability of the fixing frame.

[0010] In a preferred embodiment, the vibration reduction mechanism includes a vibration isolator and a damper, and multiple vibration isolators and dampers are provided, with multiple vibration isolators and multiple dampers distributed at intervals. The vibration isolators are detachably connected to the base and the vibration isolation plate, and the top and bottom ends of the dampers are connected to the vibration isolation plate and the base respectively through movable parts.

[0011] In a preferred embodiment, the top of the vibration isolation plate is machined with multiple fixing holes, all of which are located on the outside of the vibration isolator and damper, so as to avoid obstruction when installing equipment on the vibration isolation plate.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. By incorporating an appropriate radial constraint mechanism into the vibration isolation platform, unnecessary lateral displacement is effectively reduced, improving the platform's positioning accuracy and stability. This invention achieves vibration isolation through the cooperation of vibration isolators and dampers between the vibration isolation plate and the base. Furthermore, radial limiting plates distributed around the vibration isolation plate are installed on the base. These radial limiting plates effectively restrict excessive movement of the vibration isolation plate in the radial direction. Simultaneously, working in conjunction with the axial vibration isolators and dampers, they effectively suppress vibration interference from all directions, ensuring precise positioning of the vibration isolation plate under complex working conditions.

[0014] 2. By using a plug-in method to fix the radial limiting plate, and using a fixing frame to fix multiple plug blocks, the fixing frame can be removed, which makes it easy for staff to quickly replace the radial limiting plate, thereby improving the replacement efficiency of the radial limiting plate.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Refer to the instruction manual appendix Figures 1-6This utility model provides a self-constrained vibration isolation platform, including a base 1 and a vibration isolation plate 2. A vibration damping mechanism 3 is provided between the base 1 and the vibration isolation plate 2. Specifically, the vibration damping mechanism 3 includes vibration isolators 31 and dampers 32. Multiple vibration isolators 31 and multiple dampers 32 are provided, and the multiple vibration isolators 31 and multiple dampers 32 are distributed at intervals. The vibration isolators 31 are detachably connected to the base 1 and the vibration isolation plate 2. The top and bottom ends of the dampers 32 are connected to the vibration isolation plate 2 and the base 1 respectively through movable parts 33. The design of the movable parts 33 (such as ball joints or universal joints) allows the dampers 32 to be finely adjusted in multiple directions to adapt to vibration transmission in non-vertical directions and improve stability under complex working conditions.

[0028] To further improve the vibration isolation effect of the vibration isolation platform, a limiting component 4 is also provided on the top of the base 1. The limiting component 4 consists of multiple radial limiting plates 41 evenly distributed on the outer side of the vibration isolation plate 2. The top of the base 1 has the same number of mounting slots 42 as the radial limiting plates 41, and the radial limiting plates 41 are inserted into the mounting slots 42. The radial limiting plates 41 have a reasonable thickness and good bending resistance. A rubber gasket can also be placed between the radial limiting plates 41 and the mounting slots 42 to buffer radial impact and reduce metal-to-metal contact wear.

[0029] Multiple fixing holes 6 are machined on the top of the vibration isolation plate 2. Equipment that needs to be isolated can be installed through the fixing holes 6. Each fixing hole 6 is located on the outside of the vibration isolator 31 and the damper 32.

[0030] like Figure 4 As shown, in actual use, the equipment requiring vibration isolation is installed on the vibration isolation plate 2. Four vibration isolators 31 are distributed at intervals below the vibration isolation plate 2 along with four dampers 32. When the vibration isolators 31 transmit the vibration of the equipment, the dampers 32 are connected to the vibration isolation plate 2 and the base 1 respectively through the movable parts 33 at both ends. This allows the vibration isolation plate 2 to contract between the base 1 and work synchronously with the vibration isolators 31. The dampers 32 provide damping force and work with the vibration isolators 31 to achieve the vibration isolation effect. In addition, the four radial limiting plates 41 set on the base 1 can effectively limit the excessive movement of the vibration isolation plate 2 in the radial direction. At the same time, they work together with the axial vibration isolators 31 and dampers 32 to effectively suppress vibration interference from all directions and ensure the accurate positioning of the vibration isolation plate 2 under complex working conditions.

[0031] Refer to the instruction manual appendix Figures 1-6The base 1 has a frame-shaped groove 43 machined on its top. An installation component 5 is fitted inside the frame-shaped groove 43. The installation component 5 includes a fixing frame 51. The fixing frame 51 has the same number of insert blocks 52 as the radial limiting plates 41 inside. Each radial limiting plate 41 has an insertion hole 53 machined on its outer wall, and the insert block 52 is inserted into the insertion hole 53. Next, multiple fixing slots 56 connected to the frame-shaped groove 43 are machined on the top of the base 1. An electromagnetic lock 57 can be detachably installed inside each fixing slot 56. The electromagnetic lock 57 is located below the top plate 54. The inner wall surface of the fixing frame 51 has the same number of locking grooves 58 as the electromagnetic lock 57, and the electromagnetic lock 57 is locked into the locking grooves 58. The electromagnetic lock 57 can be linked with existing sensors to achieve automatic locking: when excessive vibration is detected, such as in an outdoor typhoon environment, the locking is triggered to prevent the equipment from dislodging.

[0032] Furthermore, the inner wall of the frame-shaped groove 43 is machined with the same number of recesses 55 as the number of inserts 52, and the recesses 55 are connected to the mounting groove 42, with the inserts 52 inserted into the recesses 55. (See reference...) Figure 5 When in use, part of the insert 52 is in the mounting groove 42 and the other part is located below the top plate 54. The part located below the top plate 54 is inserted into the recess 55. When installing the radial limiting plate 41, first insert the radial limiting plate 41 into the mounting groove 42, and then push the insert 52 from the recess 55 into the insertion hole 53 to complete the fixing of the radial limiting plate 41.

[0033] By using a plug-in method to fix the radial limiting plate 41, it is convenient for staff to quickly replace the radial limiting plate 41. After multiple radial limiting plates 41 are inserted into multiple mounting slots 42, the staff only needs to insert the plug block 52 into the groove 55, then push the plug block 52 so that the two round rods on the plug block 52 are inserted into the plug hole 53, and then put the fixing frame 51 into the frame-shaped groove 43 to complete the fixing of multiple radial limiting plates 41. The fixing frame 51 is fixed to the base 1 by the electromagnetic lock 57, which facilitates the quick disassembly of the fixing frame 51 and improves the replacement efficiency of the radial limiting plate 41.

[0034] Furthermore, a top plate 54, the same number as the insert 52, is detachably connected to the top of the fixed frame 51. The bottom of the top plate 54 contacts the top of the insert 52 for reinforcement, thereby further improving the stability of the insert 52.

[0035] The structure of this utility model, in which the radial limiting plate 41 and the axial vibration isolator 31 / damper 32 work together to effectively suppress lateral (equipment swaying) and longitudinal vibrations (such as impact loads), is suitable for precision instruments such as semiconductor equipment and optical platforms. The plug-in limiting component 4 and the detachable vibration isolator 31 / damper 32 facilitate the replacement of damaged parts or the adjustment of damping parameters (such as replacing dampers with different stiffnesses).

[0036] The various embodiments in this specification are described in a related manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model are included within the scope of protection of the present utility model.
