Abstract
Description
Technical Field
[0001] This invention relates to a vibration damping device for equipment, and more particularly to a combination nut that can be directly installed at specific positions of equipment support legs and combined with a fixing base to achieve vibration damping of machine equipment. Prior Technology
[0002] Located in the Pacific Ring of Fire, Taiwan experiences frequent earthquakes, posing a significant potential threat to many domestic industries. This is particularly true for precision industries such as wafer manufacturing, precision machinery manufacturing, and optoelectronics, where the impact of earthquakes is particularly pronounced. Even minor tremors can drastically reduce product yield. Therefore, earthquake protection measures are indeed an issue that cannot be ignored, and how to effectively reduce earthquake damage to equipment has become a problem that needs to be solved.
[0003] In the prior art, vibration damping measures for equipment mainly involve adding additional devices, such as Z-shaped mounting brackets, to the equipment's support legs. However, typical Z-shaped mounting brackets can only resist horizontal forces (X and Y axes) and cannot resist vertical forces (Z axis). To address this, Republic of China Patent Publication No. TWM321340U proposed a "machine anti-vibration fixing device," which uses a fixing nut added below the Z-shaped mounting bracket to resist vertical external forces. However, this technology has the following drawbacks: (1) Not all devices have additional retaining nuts to provide vertical fixation for the Z-mount. (2) If additional fixing nuts are required, the equipment must be removed, the fixing nuts must be screwed into the top of the equipment support foot screws, and the equipment must be reinstalled after the fixing nuts are installed. This process is obviously too cumbersome and time-consuming, and the operation is not convenient.
[0004] It is evident that existing technologies have significant shortcomings in terms of equipment vibration damping and ease of installation. Therefore, how to provide an equipment vibration damping device that can simultaneously suppress equipment vibration in both the horizontal and vertical directions and simplify the installation process is an urgent problem to be solved. Summary of the Invention
[0005] In view of the above problems, the inventor has improved the equipment anti-vibration device based on years of experience in related industries. Therefore, the main purpose of this invention is to provide an equipment anti-vibration device that is easy to assemble and disassemble, can effectively fix the machine equipment, and reduce the impact of external forces on the machine equipment.
[0006] To achieve the above objectives, the present invention provides a shock-absorbing device for equipment support legs of various machine tools, which mainly includes a combined nut and a fixing base.
[0007] The aforementioned combination nut is used to assemble on the equipment support leg. It has a pair of locking plates and a pair of threaded plates, which are assembled together through multiple assembly parts. The aforementioned fixed seat is fixedly connected to the ground through multiple fixing parts, the aforementioned combination nut, and the ground, thereby restricting the movement of the equipment support leg in the horizontal and vertical directions.
[0008] In this embodiment, after the locking plate and the threaded plate are assembled together, there is a certain gap between the threaded plates to avoid direct contact and wear. Furthermore, the threaded plates can be symmetrical or asymmetrical to suit the installation requirements of various machine tools and equipment. In addition, the threaded plates are fixed to at least one fixed base so that the anti-vibration device of the present invention can suppress external forces to the greatest extent.
[0009] To enable your review committee to clearly understand the purpose, technical features, and effects of this invention, the following description is provided in conjunction with illustrations. Please refer to them. Simple Explanation of the Diagram

[0011] Please refer to Figure 1, which is a perspective view of the present invention. As shown in the figure, the combined nut 11 of the equipment anti-vibration device of the present invention is used to assemble a support leg 2 of the equipment. It can be made of various materials according to different application requirements to improve applicability and durability. The materials can include metals, such as carbon steel, stainless steel, aluminum alloy or copper alloy, to provide a high-strength, corrosion-resistant or lightweight structure, suitable for general industrial equipment, precision machinery or marine engineering, etc.; polymer materials, such as polyetheretherketone (PEEK) and polytetrafluoroethylene (PTFE), can also be used to resist chemical corrosion, provide lightweight design or high-temperature environment resistance; in addition, composite materials, such as carbon fiber reinforced polymer (CFRP) or glass fiber reinforced polymer (GRP), can also be used. Plastic (GFRP) is used to achieve a balance between high strength and lightweight. For specific needs, a surface coating of metal or ceramic can also be used to improve corrosion resistance and wear resistance. Through the diverse material selection, the equipment shockproof device 1 of this invention can meet different environmental conditions and equipment requirements, providing a more comprehensive shockproof effect and a longer service life. It has a pair of locking plates 111 and a pair of threaded plates 112. When the two locking plates 111 and the two threaded plates 112 are assembled together, there will be a gap between the two threaded plates 112. A threaded hole 113 is formed. The diameter of the threaded hole 113 can be changed according to the specifications of the screw 21 of the equipment support foot 2. That is, the present invention does not limit the diameter of the threaded hole 113, so as to be suitable for the equipment support foot 2 of various machine tools. Furthermore, after the two threaded plates 112 and the two locking plates 111 are assembled together, there is a certain distance between the two threaded plates 112. This distance can prevent the two threaded plates 112 from directly contacting each other and thus causing wear, and can more effectively disperse stress and improve the overall durability of the combined nut 11 structure.
[0012] Please refer to Figure 2, which is an exploded view of the structure of the present invention. As shown in the figure, the locking plate 111 of the present invention is an elongated structure. Each locking plate 111 has a combination surface 1111 and a mating surface 1112, and a combination through hole 1113 is formed at both ends for a pair of assemblies 13 to pass through. The diameter of the combination through hole 1113 on the combination surface 1111 is larger than the diameter of the combination through hole 1113 on the mating surface 1112, so that when the assemblies 13 are inserted into the locking plate 111, the bolt portion 131 can pass through the combination through hole 1113 on the mating surface 1112 side of the locking plate 111, while the head 132 can be accommodated in the combination through hole 1113 on the combination surface 1111 side of the locking plate 111. Within 13; the threaded plate 112 is a structure of two symmetrically arranged pieces. Each threaded plate 112 is formed with a threaded portion 1121, a pair of combined threaded holes 1122, and a pair of fixed threaded holes 1123. The threaded portion 1121 is formed with an internal thread for the threaded plate 112 to engage with the screw 21 of the equipment support leg 2. The fixed threaded holes 1123 are formed at both ends of the opposite surface of the threaded portion 1121 to provide a structure for connection with a fixed seat 12 (not shown in the figure). The combined threaded holes 1122 are formed on the adjacent surfaces of the fixed threaded holes 1123, and their forming positions can correspond to the combined through holes 1113 on the mating surface 1112 side of the locking plate 111 to provide a structure for connection with the assembly 13.
[0013] Please refer to Figures 3 and 4, which are schematic diagrams of the structural assembly of the present invention (I) and (II). As shown in the figures, the modular nut 11 of the present invention can be screwed into the top of the screw 21 of the equipment support leg 2, or it can be directly assembled to a specific position on the screw 21 of the equipment support leg 2 through the mutual combination of the locking plate 111 and the threaded plate 112. There is no need to spend time and effort to slowly screw it into the top of the screw 21 of the equipment support leg 2. Furthermore, the modular nut 11 of the present invention can be directly assembled and installed onto the screw 21 of the equipment support leg 2 after the machine equipment has been assembled, without having to remove the machine equipment and then screw the modular nut 11 into it. First, the threaded portion 1121 of the two threaded plates 112 Align the locking plates 111 with the screw 21 of the support leg 2 of the equipment accordingly, then attach the mating surfaces 1112 of the two locking plates 111 to the combined screw hole 1122 of the threaded plate 112, and align the combined through hole 1113 of the locking plate 111 with the combined screw hole 1122 of the threaded plate 112. Then, thread the bolt part 131 of the assembly 13 through the combined through hole 1113 and screw it into the combined screw hole 1122 to connect the locking plates 111 and the threaded plate 112. Through the difference in the hole size between the mating surface 1112 of the locking plate 111 and the combined through hole 1113 of the combined surface 1111, the head 132 of the assembly 13 is held in place, so that the locking plates 111 and the threaded plate 112 can form a stable assembly connection through the assembly 13.
[0014] Please refer to Figures 5 and 6, which are schematic diagrams of the structural assembly of the present invention (III) and (IV). As shown in the figures, after the locking plate 111 and the threaded plate 112 of the combined nut 11 are assembled together, it can be fixed to at least one fixing seat 12. The fixing seat 12 can be, for example, L-shaped, N-shaped, etc., but is not limited thereto. It is formed with a pair of fixing through holes 121 and a pair of grounding through holes 122. The fixing through holes 121 are used to correspond to the fixing screw holes 1123 of the threaded plate 112, so that the bolts 141 of a pair of first fixing members 14 can be screwed into the fixing screw holes 1123 after passing through the fixing through holes 121, so as to connect the threaded plate 112 and the fixing seat 12. Since the outer diameter of the head 142 of the first fixing member 14 is larger than the inner diameter of the fixing through hole 121, the first fixing member The head 142 of the first fastener 14 is held in place by the fixing through hole 121, thereby forming a stable fixed connection between the threaded plate 112 and the fixed base 12. After the fixing through hole 121 and the fixing screw hole 1123 are fixedly connected through the first fastener 14, the bolt part 151 of the second fastener 15 is passed through the grounding through hole 122 and screwed into the ground. Since the outer diameter of the head 152 of the second fastener 15 is larger than the inner diameter of the grounding through hole 122, the head 152 of the second fastener 15 is held in place by the grounding through hole 122, thereby forming a stable fixed connection between the fixed base 12 and the ground, and thus allowing the equipment support leg 2 to be stably installed on the ground. Furthermore, the two threaded plates 112 of the combined nut 11 can simultaneously form a fixed connection with the fixed base 12, so as to suppress the external force on the machine equipment to the greatest extent.
[0015] Please refer to Figure 7, which is a schematic diagram of the implementation of the present invention. As shown in the figure, the equipment vibration damping device 1 of the present invention has the characteristics of stable structure and excellent vibration resistance, and can be widely used in various equipment that needs to maintain stability and reduce the impact of vibration, such as semiconductor equipment, scientific research and education equipment, medical and biotechnology equipment, building and facility equipment, transportation and related equipment, consumer and special application equipment, etc., but not limited thereto; when the equipment support legs 2 of the machine tool are equipped with the equipment vibration damping device 1 of the present invention, the fixed seat 12 is subjected to the force of the fixed connection between the second fixing member 15 and the ground, so that it cannot move in the horizontal direction (X, Y axis direction). The equipment support leg 2 moves in both the horizontal (X and Y axis directions) and vertical (Z axis direction) directions. Furthermore, the combined nut 11 is screwed onto the screw 21 of the equipment support leg 2 and forms a fixed connection with the fixed base 12 through the first fixing member 14. That is, the movement of the equipment support leg 2 in both the horizontal (X and Y axis directions) and vertical (Z axis direction) directions is restricted by the combined nut 11. Therefore, when an earthquake occurs, the seismic waves generated by the earthquake cannot cause the equipment support leg 2 to shake or shift, thereby ensuring that the machine equipment remains stable during an earthquake, avoiding damage to the machine equipment or products due to vibration, and further improving the reliability and safety of machine operation, as well as the yield rate of produced products.
[0016] Please refer to Figure 8, which is a schematic diagram of an embodiment (I) of the present invention. As shown in the figure, the combined nut 11 of the present invention can also be used with a Z-shaped fixing seat 16 to achieve vibration protection for the machine equipment. One notch 161 of the Z-shaped fixing seat 16 is abutted against the screw 21 of the equipment support leg 2, and the combined nut 11 of the present invention is installed below the notch 161 of the Z-shaped fixing seat 16, so that the upper surface of the combined nut 11 is in contact with the lower surface of the notch 161 of the Z-shaped fixing seat 16 to provide vertical (Z-axis direction) support force for the Z-shaped fixing seat 16. A stop plate 162 is installed on the upper surface of the notch 161 and the fixing through hole 121 through a pair of first fixing members 14 to limit the displacement of the screw 21 of the equipment support leg 2 in the horizontal direction (X, Y axis direction). The second fixing member 15 is passed through the grounding through hole 122 so that the Z-shaped fixing seat 16 forms a stable fixed connection with the ground, thereby allowing the equipment support leg 2 to be stably installed on the ground.
[0017] Please refer to "Figure 9" and "Figure 10", which are schematic diagrams (1) and (2) of the structural combination of the second embodiment of the present invention. As shown in the figures, in addition to the aforementioned rectangular shape, the outer shape of the combined nut 11 of the present invention can be replaced with different shapes according to the on-site environmental requirements of the installation of machine equipment, such as the shape of "丄", "丅", or "工", but not limited thereto; it is achieved by changing and replacing the outer shape of the thread piece 112 so that the thread piece 112 becomes a symmetric or asymmetric structure to meet the installation requirements of various machine equipment. In this embodiment, the "丄"-shaped combined nut with an asymmetric setting will be used as an example for illustration. First, the thread portions 1121 of the two thread pieces 112 are correspondingly aligned with the positions of the screws 21 of the equipment support feet 2 to be assembled. Then, the joint surfaces 1112 of the two locking pieces 111 are attached to the combined screw holes 1122 of the thread piece 112, and the combined through holes 1113 of the locking pieces 111 are aligned with the combined screw holes 1122 of the thread piece 112. Then, the bolt portion 131 of the combined part 13 is passed through the combined through hole 1113 and screwed with the combined screw hole 1122 to connect the locking piece 111 and the thread piece 112. Through the difference in the aperture sizes of the joint surface 1112 of the locking piece 111 and the combined through hole 1113 of the combined surface 1111, the head 132 of the combined part 13 is抵住, so that the locking piece 111 and the thread piece 112 can form a stable assembled connection through the combined part 13.
[0018] It should be noted that there seems to be an incorrect character "抵住" in the original Chinese text. I have translated it as "抵住" as it is, but it might need to be corrected in the original for a more accurate translation.Please refer to "Figure 11" and "Figure 12", which are schematic diagrams (III) and (IV) of the structural combination of the second embodiment of the present invention. As shown in the figures, after the locking piece 111 and the thread piece 112 of the "丄"-shaped combined nut 11 are assembled with each other, it can be fixedly connected to at least one fixing base 12. The fixing base 12 is formed with a pair of fixing through holes 121 and a pair of grounding through holes 122. The fixing through holes 121 are used to correspond to the fixing screw holes 1123 of the thread piece 112. After a pair of bolt parts 141 of the first fixing members 14 pass through the fixing through holes 121, they are screwed with the fixing screw holes 1123 to connect the thread piece 112 and the fixing base 12. And because the outer diameter of the head 142 of the first fixing member 14 is larger than the inner diameter of the fixing through hole 121, therefore, the head 142 of the first fixing member 14 will be resisted by the fixing through hole 121, so that the thread piece 112 and the fixing base 12 form a stable fixed connection. Also, after the fixing through hole 121 and the fixing screw hole 1123 are fixedly connected through the first fixing member 14, then the bolt part 151 of a second fixing member 15 is passed through the grounding through hole 122 and screwed with the ground. And because the outer diameter of the head 152 of the second fixing member 15 is larger than the inner diameter of the grounding through hole 122, therefore, the head 152 of the second fixing member 15 will be resisted by the grounding through hole 122, making the fixing base 12 and the ground form a stable fixed connection, so that the equipment support leg 2 can be firmly installed on the ground. Also, the two thread pieces 112 of the "丄"-shaped combined nut 11 can be fixedly connected to the fixing base 12 at the same time, so that the external force received by the machine equipment can be suppressed to the greatest extent.
[0019] As can be seen from the above, the equipment shockproof device of the present invention is used to be assembled on an equipment support leg, and it has a combined nut and a fixing base. The combined nut is a detachable structure and can be directly assembled at a specific position of the equipment support leg without screwing in from the top of the stud. The combined nut is assembled with the fixing base through a plurality of fixing members, so that its activities in the horizontal and vertical directions are restricted. And the combined nut is screwed to the stud of the equipment support leg through the internal thread of the thread part, so that the activities of the equipment support leg in the horizontal and vertical directions are also restricted, thereby achieving the effect of stabilizing the machine equipment. To sum up, after the present invention is implemented, it can indeed achieve the purpose of providing an equipment shockproof device that is convenient for disassembly and assembly, can effectively fix the machine equipment, and reduce the influence of external forces on the machine equipment.
[0020] However, the above are only the preferred embodiments of the present invention and are not used to limit the scope of implementation of the present invention. Any equivalent changes and modifications made by those skilled in this art without departing from the spirit and scope of the present invention should be covered within the patent scope of the present invention.
