Buffer piston structure and fragile component mounting device

Abstract

The application discloses a buffer piston structure and a fragile component mounting device. The buffer piston structure comprises two cylinder body parts and two piston parts. The two cylinder body parts are used for arranging filling bodies. The two piston parts are respectively correspondingly and movably arranged in the cavities of the two cylinder body parts. The two piston parts are connected and arranged in linkage. A resistance flow channel is formed on the buffer piston structure. The resistance flow channel is communicated with the cavities of the two cylinder body parts. When the piston parts move in the cylinder body parts, the filling bodies in one of the cylinder body parts are slowly transmitted to the other cylinder body part through the resistance flow channel. The buffer piston structure can solve the problems that the piston can slowly move when the component is slowly stressed, and the piston can also keep relatively slow movement when the component is rapidly stressed. The buffer piston structure is applied to the fixing problems of the component products which cannot bear rigid stress and have slow response time.

Description

Technical Field

[0001] This invention relates to the field of industrial compressor technology, and in particular to a buffer piston structure and a device for mounting fragile parts. Background Technology

[0002] Currently, optical fibers consist of a core, cladding, and coating, with the core and cladding primarily made of silicon dioxide.

[0003] Fiber optic structural devices refer to devices that are made of optical fiber through certain processing to give them specific characteristics and functions. Examples include: gratings, mode field adapters, cladding strippers, fiber combiners, and fiber couplers.

[0004] Since the main body of fiber optic structural devices is still made from fiber optics, they are prone to breakage under stress. When subjected to stress, these devices undergo slight deformation, leading to changes in some of their characteristics. For example, the spot size of the laser beam propagating within the fiber will change under stress.

[0005] Common sources of stress on fiber optic structural devices include: first, when subjected to vibration and impact, the fiber optic structure experiences a certain acceleration, thus incurring stress; second, when the two ends of the fiber are fixed to a substrate, the coefficients of thermal expansion and contraction of the fiber and the substrate are inconsistent when the ambient temperature changes, resulting in the fiber being subjected to tension or compressive force.

[0006] For example in Figure 1 In this structure, optical fiber structural components are bonded to the substrate using adhesive. If the adhesive is rigid, the fiber is rigidly connected to the substrate. Under vibration and impact, the force on the optical fiber structural component is aligned with the fiber's axis. Since the magnitude of the force is related to acceleration and mass, generally, a smaller mass results in a smaller axial force on the fiber, preventing breakage. However, when the ambient temperature changes, the optical fiber structural component experiences greater tensile or compressive stress, causing changes in the internal laser beam spot. If the adhesive is flexible, the fiber is softly connected to the substrate. Vibration and impact may cause misalignment of the fiber, leading to a misalignment of the force direction with the fiber's axis and potentially causing breakage. When the ambient temperature changes, the fiber contracts on the flexible adhesive, resulting in less tensile or compressive stress. In summary, regardless of whether rigid or flexible adhesive is used, the optical fiber structural component may either experience changes in the laser beam spot or breakage. Summary of the Invention

[0007] The main objective of this invention is to overcome the shortcomings of the prior art by proposing a buffer piston structure and a mounting device for fragile parts. This invention aims to solve the problem of fixing parts that cannot be rigidly stressed and have slow response times, where the piston can move slowly under slow stress and maintain a relatively slow movement under rapid stress.

[0008] To achieve the above objectives, the present invention proposes a buffer piston structure, comprising:

[0009] Two cylinder sections for housing the filler; and,

[0010] Two piston sections are respectively and sealed and movably installed in the cavities of the two cylinder sections, and the two piston sections are linked together;

[0011] A resistance flow channel is formed on the buffer piston structure, the resistance flow channel connecting the cavities of the two cylinder parts, so that when the piston part moves inside the cylinder part, the filler in one of the cylinder parts is slowly transferred to the other cylinder part through the resistance flow channel.

[0012] Optionally, the two piston sections are integrally disposed; and / or,

[0013] The two cylinder sections are integrally formed.

[0014] Optionally, the buffer piston structure includes a cylinder body, and a piston is disposed within the cylinder body;

[0015] The two piston portions include the opposite ends of the pistons;

[0016] The two cylinder sections include the opposite ends of the cylinder.

[0017] Optionally, the resistance channel is formed on the piston.

[0018] Optionally, the resistance flow channel is formed between the piston and the inner wall of the cylinder.

[0019] Optionally, the resistance flow channel is formed between opposite ends of the cylinder block.

[0020] Optionally, the piston is a rigid piston.

[0021] Optionally, the buffer piston structure further includes a filler comprising anhydrous propanol, and the corresponding resistance flow channel comprises a capillary.

[0022] The present invention also proposes a device for mounting fragile components, the device including the buffer piston structure, comprising:

[0023] Two cylinder sections for housing the filler; and,

[0024] Two piston sections are respectively and sealed and movably installed in the cavities of the two cylinder sections, and the two piston sections are linked together;

[0025] A resistance flow channel is formed on the buffer piston structure, the resistance flow channel connecting the cavities of the two cylinder parts, so that when the piston part moves inside the cylinder part, the filler in one of the cylinder parts is slowly transferred to the other cylinder part through the resistance flow channel.

[0026] Optionally, the fragile component body includes an optical fiber device.

[0027] In the technical solution provided by this invention, the installation steps are simple for the operator, and it is ensured that when the fragile component is subjected to a strong but short-duration impact, the piston part of the buffer piston structure can move slowly between the two cylinder parts. When the time is very short, the piston part hardly moves. When the fragile component is subjected to thermal expansion and contraction from the external environment, the thrust and tension on the fragile component are very small and the force is applied for a long time. At this time, the piston part of the buffer piston structure can move synchronously, so that the fragile component will not be subjected to excessive force. This ensures that the fragile component will not bear large short-term tension or pressure, nor will it bear large long-term tension or pressure, thereby protecting the fragile component from damage or changes in certain properties due to force.

[0041] Currently, optical fibers consist of a core, cladding, and coating, with the core and cladding primarily made of silicon dioxide.

[0042] Fiber optic structural devices refer to devices that are made of optical fiber through certain processing to give them specific characteristics and functions. Examples include: gratings, mode field adapters, cladding strippers, fiber combiners, and fiber couplers.

[0043] Since the main body of fiber optic structural devices is still made from fiber optics, they are prone to breakage under stress.

In summary, regardless of whether rigid or flexible adhesive is used, the optical fiber structural component may either experience changes in the laser beam spot or breakage.

[0046] In view of this, the present invention provides a buffer piston structure 10. Figures 3-6 Four embodiments are provided for this invention.

[0047] Please see Figure 3 The diagram illustrates an embodiment of the present invention, proposing a buffer piston structure 10. The buffer piston structure 10 includes two cylinder sections 1 and two piston sections 2. The two cylinder sections 1 are used to house a filler 11. The two piston sections 2 are respectively and sealingly movably installed in the cavities of the two cylinder sections 1, and are linked together. A resistance flow channel 3 is formed on the buffer piston structure 10, connecting the cavities of the two cylinder sections 1. This resistance flow channel 3 allows the filler 11 in one cylinder section 1 to be slowly transferred to the other cylinder section 1 through the resistance flow channel 3 when the piston section 2 moves inside the cylinder section 1. This design aims to solve the problem of piston 2a moving slowly under slow stress and maintaining relatively slow movement under rapid stress, thus addressing the fixation issues arising from components that cannot be rigidly stressed and have slow response times.

[0048] In the technical solution provided by this invention, the installation steps are simple for the operator, and it is ensured that when the fragile component is subjected to a strong and short-duration impact force, the piston part 2 of the buffer piston structure 10 can move slowly between the two cylinder parts 1. When the time is very short, the piston part 2 hardly moves. When the fragile component is subjected to thermal expansion and contraction from the external environment, the thrust and tension on the fragile component are very small and the force is applied for a long time. At this time, the piston part 2 of the buffer piston structure 10 can move synchronously, so that the fragile component will not be subjected to excessive force. This ensures that the fragile component will not bear large short-term tension or pressure, nor will it bear large long-term tension or pressure, thereby protecting the fragile component from damage or changes in certain properties due to force.

[0049] In this embodiment, the two piston portions 2 are integrally formed, and the two cylinder portions 1 are integrally formed, as can be referred to. Figures 3 to 5 .

[0050] Furthermore, the buffer piston structure 10 includes a cylinder body 1a, a piston 2a is disposed in the cylinder body 1a, the two piston parts 2 include the opposite ends of the piston 2a, and the two cylinder parts 1 include the opposite ends of the cylinder body 1a.

[0051] Please refer to Figure 3 The resistance flow channel 3 can be disposed on the piston 2a, as can be referred to. Figure 4 The resistance flow channel 3 can also be disposed between the inner wall of the piston 2a and the cylinder 1a, as can be referred to. Figure 5 The resistance flow channel 3 may also be disposed between the two opposite ends of the cylinder 1a, wherein the resistance flow channel 3 is a functional overview.

[0052] Please refer to Figure 6 In another embodiment, the cylinders 1a may be spaced apart by a certain distance, and the pistons 2a are movably connected to the two cylinders 1a respectively. One end of the resistance flow channel 3 may be located on the left side of one of the cylinders 1a, and the other end of the resistance flow channel 3 may be located on the right side of the other cylinder 1a; or one end of the resistance flow channel 3 may be located on the right side of one of the cylinders 1a, and the other end of the resistance flow channel 3 may be located on the left side of the other cylinder 1a.

[0053] Furthermore, the piston 2a is preferably a rigid piston 2a. From a mechanical point of view, the piston 2a is preferably a lightweight rigid piston 2a, which has the advantages of being less prone to deformation and having a small mass.

[0054] In one embodiment, the packing 11 includes anhydrous propanol 11a, and the corresponding resistance flow channel 3 can be configured as a set of capillary tubes 3a. When the piston 2a is under force, the anhydrous propanol 11a flows to the other side through the capillary tubes. The anhydrous propanol 11a is a colorless and transparent liquid with a slight ethanol odor. It can be produced by absorbing a raw material gas containing more than 50% propylene with concentrated sulfuric acid of 75-6-85% at 50°C and low pressure to generate isopropyl bisulfate. The isopropyl bisulfate is then hydrolyzed to isopropanol. After crude distillation to 95% in a distillation column, followed by benzene extraction, water separation, and distillation, a product containing more than 99% isopropanol can be obtained. Alternatively, propylene and water can be pressurized to 1.96 MPa and preheated to 200°C, mixed, and added to a reactor for a hydration reaction. After neutralization and heat exchange, the reactant gas is sent to a high-pressure cooler and a high-pressure separator. Isopropanol in the gas phase is recovered by spraying with deionized water in a recovery tower. An 85%–87% isopropanol aqueous solution is obtained by distillation in a rough distillation tower, then concentrated to 95% in another distillation tower, and finally extracted with benzene to obtain isopropanol with a purity of over 99%. The capillary 3a mentioned here typically refers to a thin tube with an inner diameter equal to or less than 1 mm.

[0055] In another embodiment, the filler 11 may be anhydrous propanol 11a, and the resistance flow channel 3 is a set of fine grooves between the piston 2a and the cylinder wall. When the piston 2a is under force, the anhydrous propanol 11a flows to the other side through the fine grooves.

[0056] The filler 11 and the resistance channel 3 work together. The resistance channel 3 can be set by the filler 11, and the filler 11 can be set by the resistance channel 3. The choice of the filler 11 is not limited. It can be a gaseous, liquid, or glassy fluid. The resistance channel 3 can be selected by the filler 11. As mentioned above, it can be a set of capillary tubes 3a or a set of fine grooves between the piston 2a and the cylinder wall. Obviously, the choice is not limited to these. As long as the cooperation between the filler 11 and the resistance channel 3 can meet the requirement that when the piston 2a is under force and the piston part 2 moves inside the cylinder part 1, the filler 11 in one of the cylinder parts 1 is slowly transferred to the other cylinder part 1 through the resistance channel 3.

[0057] The present invention also proposes a device 100 for mounting fragile components, as shown in the reference. Figure 2The fragile component mounting device 100 includes a fragile component body 20, a base material 30, a support part 40, and the aforementioned buffer piston structure 10. The base material 30 is disposed on the piston 2a and is fixedly connected to one end of the fragile component body 20. The support part 40 is fixedly connected to the other end of the fragile component body 20 and is used to support the fragile component body 20 and make the fragile component body 20 parallel to the plane of the reference object 50. The reference object can be any surface that can be placed, such as the ground, a tabletop, or an installation platform, as long as it can accommodate the buffer piston structure 10. The support part 40 can also be a support column or a support shaft, as long as it can support the fragile component body 20 and make the fragile component body 20 parallel to the plane of the reference object 50. Since this fragile component mounting device 100 adopts all the technical solutions of the above embodiments, it also has the technical effects brought about by the technical solutions of the above embodiments, and will not be described in detail here.

[0058] In one embodiment, the fragile component body 20 can be an optical fiber device 20a. The optical fiber is short for optical waveguide fiber, a type of fiber made of glass or plastic, composed of two layers of glass with different refractive indices. The inner layer is the optical core, with a diameter ranging from a few micrometers to tens of micrometers, while the outer layer has a diameter of 0.1 to 0.2 mm. Generally, the refractive index of the inner core glass is 1% greater than that of the outer layer glass. According to the principles of light refraction and total internal reflection, when the angle at which light strikes the interface between the inner core and the outer layer is greater than the critical angle for total internal reflection, the light cannot pass through the interface and is completely reflected. In another embodiment, the fragile component body 1 can also be a glass tube; any fragile and easily damaged component can be used in the device of this invention.

[0059] Since the piston 2a and the fragile component body 20 are not easily connected, in this embodiment, a base material 30 is provided. The base material 30 connects one end of the fragile component body 20 to the piston 2a, which has the advantage of making installation easier. In order to make the fragile component body 20 parallel to the plane where the reference object 50 is located, and to make the fragile component body 20 more stable and the installation more secure, a support column is provided between the other end of the fragile component body 20 and the reference object 50.

[0060] The installation of the fragile component mounting device 100 includes the following steps: First, fill the two cylinders 1a with filler 11; then, respectively seal and movably install the two pistons 2 into the cavities of the two cylinders 1, so that the two pistons 2 are linked together; finally, provide a resistance flow channel 3 on the buffer piston structure 10, the resistance flow channel 3 connecting the cavities of the two cylinders 1, so that when the piston 2 is subjected to external force, the filler 11 of one of the two cylinders 1a can be cushioned. The material is slowly transported to another cylinder 1a; the bottom of the buffer piston structure 10 is fixed to the reference object 50; the substrate 30 is fixed to the piston 2a; the support part 40 is fixed to the reference object 50 corresponding to the height of the substrate 30 to the reference object 50, such that the line connecting the support part 40 and the substrate 30 is parallel to the plane of the reference object 50; finally, one end of the fragile component body 20 is fixed to the upper part of the substrate 30, and the other end is fixed to the support part 40. The substrate 30 includes materials such as plywood, gypsum board, wood framing, putty powder, cement sand, and light steel framing.

[0061] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
