Description

Technical Field

[0001] This application relates to the field of gas spring technology, and more particularly to a tooling. Background Technology

[0002] A gas spring is an industrial component that provides support, cushioning, braking, height adjustment, and angle adjustment, and is widely used in the field of mechanical manufacturing. A gas spring mainly consists of a piston rod, piston, sealing guide sleeve, filler, pressure cylinder, and connector. The pressure cylinder is a sealed cavity filled with inert gas or an oil-gas mixture. The pressure inside the cavity is several times or tens of times atmospheric pressure. When the gas spring operates, the pressure difference between the two sides of the piston drives the movement of the piston rod.

[0003] In practical use, gas springs need to be compressed to a certain length before installation or removal. In scenarios with heavy loads or limited installation space, specific auxiliary tooling is often required to compress the gas spring for installation or removal. Currently, auxiliary tooling for gas springs is difficult to adapt to various stroke lengths and different end structure types with the same tooling, resulting in poor applicability and hindering the improvement of installation efficiency. Utility Model Content

[0004] This application provides a tooling that enables the installation or disassembly of gas springs with different stroke lengths and end structure types. It has wide applicability and can significantly improve the installation and disassembly efficiency of gas springs.

[0005] This application provides a tooling for installing or removing a gas spring, including a guide rail and a first support and a second support located on the guide rail. The first support and the second support are distributed sequentially along the length direction of the guide rail. The first support is fixed to the guide rail, and the second support is movable along the length direction of the guide rail. The tooling also includes a first assembly seat and a second assembly seat, which are respectively assembled onto the first support and the second support seat in a detachable manner. The first assembly seat is used to engage with one end of the gas spring, and the second assembly seat is used to engage with the other end of the gas spring.

[0006] By moving the second support, the gas spring can be compressed or reset, enabling its installation or removal. The movement of the second support also changes the distance between it and the first support, making the distance between the two supports adjustable. This allows for the matching of gas springs with different stroke lengths or length specifications, achieving compatibility of various gas springs with the same tooling. Furthermore, the first and second mounting bases are detachably fitted to the first and second supports, respectively, allowing for convenient replacement of the first and second mounting bases. Based on the end structure characteristics of the gas spring, suitable first and second mounting bases can be selected and installed on the first and second supports, enabling the same tooling to match gas springs with different end structure types. This significantly improves the practicality of the tooling, increases installation efficiency, and offers excellent convenience and low installation costs.

[0007] In one possible implementation, the first support includes a first top surface and a first side surface, the first top surface facing the second support, and the first side surface surrounding the side of the first top surface facing away from the second support.

[0008] The first support has a first mounting groove that extends to the first top surface and the first side surface. The first mounting groove is used to accommodate and fix the first assembly base.

[0009] The first mounting groove extends to the first top surface and the first side surface, forming openings on the first top surface and the second side surface. On the one hand, this avoids the gas spring being assembled, improving integration and reducing the size of the first support. On the other hand, the first mounting base can be pushed into the first mounting groove from the side of the first support, facilitating the assembly and disassembly of the first mounting base and the first support.

[0010] The second support includes a second top surface and a second side surface. The second top surface faces the first support, and the second side surface is arranged around the side of the second top surface that faces away from the first support.

[0011] The second support has a second mounting groove that extends to the second top surface and the second side surface. The second mounting groove is used to accommodate and fix the second assembly.

[0012] The second mounting groove extends to the second top surface and the second side surface, forming openings on the second top surface and the second side surface. The second mounting base can be pushed into the second mounting groove from the side of the second support, which facilitates the assembly and disassembly of the second mounting base and the first support, and helps to improve integration and reduce the size of the second support.

[0013] In one possible implementation, the first mounting base includes a third top surface facing the second mounting base, and a first positioning groove is provided on the first mounting base, the first positioning groove extending at least to the third top surface, the first positioning groove being used to engage with one end of the gas spring.

[0014] The first positioning groove extends to the third top surface, forming an opening on the third top surface, which facilitates the gas spring to be assembled into the first positioning groove through the opening. This allows the first mounting base to completely cover the end of the gas spring, improving the assembly firmness between the first mounting base and the gas spring.

[0015] The second mounting base includes a fourth top surface facing the first mounting base. A second positioning groove is formed on the second mounting base, extending at least to the third top surface. The second positioning groove is used to mate with the other end of the gas spring. By extending the second positioning groove to the fourth top surface, the second mounting base can also completely enclose the end of the gas spring, improving the assembly firmness.

[0016] In one possible implementation, the outer wall of the guide rail has external threads distributed along the length of the guide rail, and the guide rail is rotatably mounted.

[0017] The tooling also includes a mating part. The second support is fixed to the mating part, which is sleeved on the guide rail. The inner wall of the mating part has an internal thread that mates with the external thread.

[0018] The guide rail component, when rotated, drives the second support to move along its length via a mating component, thus enabling the second support to move along its length. Because the guide rail component and the mating component are threadedly engaged, the second support does not move along the guide rail component when it is not rotating. Therefore, when the second support moves to a predetermined position, the threaded engagement achieves self-locking of the second support, ensuring that it is relatively fixed relative to the guide rail component at that position. This maintains the distance between the first and second supports, thereby maintaining the compressed length of the gas spring.

[0019] In one possible implementation, the tooling also includes guide members, the length direction of which is consistent with the length direction of the guide rail members, and the guide members and guide rail members are distributed at intervals.

[0020] The first support is fixed relative to the guide, while the second support can slide along the length of the guide.

[0021] The guide component can guide and limit the movement of the second support, and the guide rail component also guides and limits the movement of the second support, so that the second support moves linearly along the length direction and does not rotate around the length direction, thereby improving the stability and reliability of the gas spring compression or reset operation.

[0022] In one possible implementation, there are at least two guide members, with the distribution direction of one guide member and guide rail member intersecting at least the distribution direction of the other guide member and guide rail member. This arrangement of at least two guide members and guide rail members in a triangular configuration further improves the stable guidance and support for the movement of the second support, and further enhances the stability and reliability of the tooling during the compression or reset of the gas spring.

[0023] In one possible implementation, the tooling further includes a first bearing, which includes a sleeve and rolling elements rolled within the sleeve.

[0024] A sleeve is fitted onto the guide member, and the rolling element contacts the guide member, allowing the first bearing to slide along the length of the guide member. The second support is fixed to the sleeve. This allows the second support to slide along the guide member via the first bearing, improving the smoothness of the second support's sliding on the guide member and enhancing the user experience.

[0025] In one possible implementation, the fixture further includes an adjusting component located on the side of the first support facing away from the second support. The guide rail passes through the first support and is fixed relative to the adjusting component. The adjusting component is used to drive the guide rail to rotate. By rotating the adjusting component, the guide rail can be rotated, making the installation and disassembly of the gas spring safe, efficient, and labor-saving.

[0026] In one possible implementation, the tooling also includes a second bearing located on the side of the first support facing away from the second support.

[0027] The second bearing includes a housing ring and a shaft ring rotatably disposed on one side of the housing ring. The second bearing is sleeved on the guide rail and is located between the first support and the adjusting member. The housing ring is fixed relative to the side of the first support facing the adjusting member, and the shaft ring is fixed relative to the adjusting member.

[0028] The adjustment component can rotate relative to the first support via the second bearing, which in turn allows the adjustment component to drive the guide rail component to rotate relative to the first and second supports. This improves the smoothness of the adjustment component's rotation, thereby enhancing the smoothness of the second support's sliding and improving the user experience. Furthermore, it can reduce or prevent damage to the first support caused by friction between the adjusting component and the first support.

[0029] In one possible implementation, the guide rail component includes a main body and two ends. Along the length of the guide rail component, the two ends are located at opposite ends of the main body, and the diameters of the two ends are smaller than the diameter of the main body. This facilitates the assembly of the guide rail component with the first support, the second support, and the second bearing. Attached Figure Description

[0051] The technical solution provided in this application will be described below with reference to the accompanying drawings.

[0052] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0053] In the description of this application, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0054] The terms "first," "second," and "third" (if any) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein.

[0055] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such as a process, method, system, product, or maintenance tool that includes a series of steps or units, not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or maintenance tool.

[0056] This application provides a tooling for installing or removing gas springs, for example, for installing or removing nitrogen gas springs. This tooling is applicable to scenarios where gas springs are used in industries such as food machinery and medical devices. For example, this tooling can be used in semiconductor manufacturing equipment where gas springs are used to open and close covers and equipment housings.

[0057] A gas spring is an industrial component that provides support, cushioning, braking, height adjustment, and angle adjustment. Due to its miniaturization, stable operation, ease of use, and affordable price, gas springs are widely used in opening and closing mechanisms in industries such as food machinery and medical devices. For example, the commonly used nitrogen gas spring has a compressible stroke of 50mm to 300mm, and the reaction force of the compressed gas ranges from 50N to 1000N (at a temperature of 20℃). In practical applications, due to varying installation environments and requirements, gas springs need to be compressed to a certain length before installation or disassembly. For gas springs with smaller load capacities, manual compression can be used to achieve installation and disassembly. However, for gas springs with larger load capacities, manual compression is prone to slippage and cannot stably compress to the desired length, making it very difficult. Therefore, specific installation tools are required for compression to achieve installation and disassembly.

[0058] Currently, common auxiliary tooling for gas spring installation and removal mostly involves fixing the gas spring to the compression mechanism of the tooling and applying pressure to one side of the gas spring to compress it to the required length for installation and removal. However, the compression structure length is often limited, resulting in a limited compression length and making it impossible to adapt the same tooling to gas springs with various stroke lengths. Furthermore, it's understandable that the end connectors of gas springs have diverse structural designs, and current auxiliary tooling is mostly designed with matching interfaces for specific gas spring models. For example, common tooling is often designed for the end of spherical gas springs, making it impossible to adapt the same tooling to gas springs with different end structure types. This leads to poor applicability of the tooling used for gas spring installation and removal, requiring different tooling to be used for different installation scenarios, which is detrimental to improving installation efficiency, has poor portability, and results in higher installation costs.

[0059] Based on this, this application provides a tooling comprising a guide rail and a second support mounted on the guide rail. A first mounting base on the first support and a second mounting base on the second support are respectively used to mate with both ends of the gas spring, and the second support is movable along the length of the guide rail. By moving the second support, compression or reset operations of the gas spring can be achieved, thereby enabling the installation or disassembly of the gas spring. The installation and disassembly process is safe, efficient, and convenient. The movement of the second support can change the distance between it and the first support, making the distance between the first and second supports adjustable. This allows for the matching of gas springs with different stroke lengths or different length specifications, enabling the same tooling to adapt to gas springs of various stroke lengths or length specifications. Furthermore, the first and second mounting bases are detachably fitted with the first and second supports, respectively, enabling convenient replacement of the first and second mounting bases. Based on the end structure characteristics of the gas spring, the appropriate first and second mounting bases can be selected and fitted onto the first and second supports, allowing the same tooling to match gas springs with different end structure types. This significantly improves the practicality of the tooling, increases installation efficiency, and offers excellent convenience and low installation costs.

[0060] Figure 1 This is a schematic diagram of the structure of a tooling provided in an embodiment of this application.

[0061] See Figure 1 As shown, the tooling 100 includes a guide rail 10 and two supports, such as a first support 20 and a second support 30, which are assembled onto the guide rail 10. For example, the guide rail 10 can be a columnar rod structure, such as a cylindrical structure. The length direction of the guide rail 10 can be consistent with the axial direction of the guide rail 10, for example, the x-direction in the figure, which can be a linear direction. It should be noted that the x-direction shown in the figure is only one example of the length direction of the guide rail; in some other examples, the length direction of the guide rail can be parallel to and opposite to the x-direction in the figure.

[0062] The first support 20 and the second support 30 are disposed on the guide rail 10, and the first support 20 and the second support 30 can be distributed sequentially along the length direction of the guide rail 10.

[0063] The tooling 100 also includes a first mounting base 22 and a second mounting base 32. The first mounting base 22 is mounted on the first support 20, and the second mounting base 32 is mounted on the second support 30.

[0064] Figure 2 for Figure 1 A schematic diagram of the tooling and gas spring assembly.

[0065] Combination Figure 2As shown, the gas spring 200 may include two opposite ends along the extension and retraction direction of the gas spring 200, for example, one end of the pressure cylinder 201 of the gas spring 200 facing away from the piston rod 202, and one end of the piston rod 202 of the gas spring 200 facing away from the pressure cylinder 201.

[0066] The first mounting base 22 can be fixed to one end of the gas spring 200, and the second mounting base 32 can be fixed to the other end. For example, the end of the pressure cylinder 201 of the gas spring 200 facing away from the piston rod 202 can be fixed to the first mounting base 22, and the end of the piston rod 202 of the gas spring 200 facing away from the pressure cylinder 201 can be fixed to the second mounting base 32, thereby fixing the gas spring 200 onto the tooling 100. The first mounting base 22 and the second mounting base 32 can fix the gas spring 200, improving the safety when assembling the gas spring.

[0067] The first support 20 is fixedly mounted on the guide rail 10, meaning that the first support 20 will not move along the length of the guide rail 10. For example, see... Figure 2 As shown, the first support 20 can be fixed to the end 12 of one end of the guide rail 10 along its length.

[0068] For example, a through hole (not shown in the figure) may be provided on the first support 20. The through hole can extend through the first support 20 along its length. One end of the guide rail 10 can pass through the through hole on the first support 20 and be fixed together with the first support 20. The through hole can be a via hole, or, in some examples, the through hole can also be a threaded hole.

[0069] The second support 30 can move along the length of the guide rail 10, that is, the second support 30 can move towards or away from the first support 20 along the length direction (x direction). After the gas spring 200 is assembled on the first mounting base 22 and the second mounting base 32, the gas spring 200 can be compressed by moving the second support 30 towards the first support 20, such as compressing the gas spring 200 to a certain length, so as to facilitate the installation or removal of the gas spring 200. By moving the second support 30 away from the first support 20, the gas spring 200 can be stretched, such as restoring the compressed gas spring 200, so as to facilitate the removal of the gas spring 200.

[0070] The second support 30 can move along its length toward or away from the first support 20, changing the distance between the first support 20 and the second support 30. This makes the distance between the first support 20 and the second support 30 adjustable, allowing gas springs 200 of various lengths to be accommodated between the first support 20 and the second support 30. This enables the matching of gas springs 200 with different stroke lengths or different length specifications. It allows for the compression or reset of gas springs 200 with different stroke lengths or different length specifications. This achieves the adaptation of the same tooling 100 to gas springs 200 with various stroke lengths or different length specifications, significantly improving the applicability of the gas springs 200, reducing or avoiding the replacement of multiple tooling 100s, improving installation efficiency, and providing high convenience and low installation costs.

[0071] The first mounting base 22 can be detachably mounted on the first support 20, that is, the first mounting base 22 can be fixed on the first support 20, or the first mounting base 22 can be detached from the first support 20, which enables the portable installation and flexible replacement of the first mounting base 22.

[0072] The second mounting base 32 can also be detachably mounted on the second support 30. That is, the second mounting base 32 can be fixedly mounted on the second support 30, or the second mounting base 32 can be detached from the second support 30, which enables the portable installation and flexible replacement of the second mounting base 32.

[0073] The first mounting base 22 and the second mounting base 32 can be easily disassembled and separated from the first support 20 and the second support 30, respectively, allowing for convenient replacement of the first mounting base 22 and the second mounting base 32. Based on the structural features of the end 12 of the gas spring 200, the appropriate first mounting base 22 and the second mounting base 32 can be selected and mounted on the first support 20 and the second support 30, making the first mounting base 22 and the second mounting base 32 replaceable to adapt to gas springs 200 with different end 12 structural types. This enables the same tooling 100 to match gas springs 200 with different end 12 structural types, further improving the practicality of the tooling 100, increasing installation efficiency, and providing greater convenience and lower installation costs.

[0074] Figure 3 for Figure 1 A schematic diagram of the structure of the first assembly base in the tooling. Figure 4 This is a schematic diagram of the structure of the first mounting base in another tooling provided in an embodiment of this application.

[0075] For example, to assemble the first mounting base 22 with one end of the gas spring, see... Figure 3 As shown, a first positioning groove 221 is provided on the first mounting base 22, and the first positioning groove 221 can cooperate with one end of the gas spring along the extension direction.

[0076] Correspondingly, a second positioning groove 321 may also be provided on the second mounting base 32 (see reference). Figure 2 As shown), the second positioning groove 321 can be engaged with the other end of the gas spring along the extension direction.

[0077] The shapes of the first positioning groove 221 and the second positioning groove 321 can be adapted to the structural features of the two ends of the gas spring, so that the first mounting base 22, the second mounting base 32 and the two ends of the gas spring are stably fitted. For example, see Figure 3 As shown, the first positioning groove 221 and the second positioning groove 321 can be grooves with a spherical circumferential profile, used to adapt to a ball-hinged gas spring with a spherical end structure. Alternatively, see... Figure 4 As shown, the first positioning groove 221 and the second positioning groove 321 can be grooves with a polygonal circumferential profile, used to adapt to the side joint type gas spring.

[0078] By replacing the first mounting base 22, which has a different structural shape from the first positioning groove 221, and the second mounting base 32, which has a different structural shape from the second positioning groove 321, the tooling 100 can be adapted to gas springs with different end structure types.

[0079] The molding material of the first mounting base 22 and the second mounting base 32 may include one or more of metal, plastic, ceramic, etc., and the specific material can be selected and set according to actual needs.

[0080] To enable the assembly and disassembly of the first mounting base 22 on the first support 20, exemplarily, in combination with Figure 1 and Figure 2 As shown, a first mounting groove 21 can be provided on the first support 20, and the first mounting base 22 can be accommodated and fixed in the first mounting groove 21.

[0081] Correspondingly, a second mounting groove 31 can also be provided on the second support 30, and the second mounting base 32 can be accommodated and fixed in the second mounting groove 31.

[0082] The detachable connection between the first mounting base 22 and the first support 20 can be achieved in various ways. For example, the first mounting base 22 and the first support 20 can be detachably connected by a threaded connection. For instance, a threaded hole 222 can be provided on the first mounting base 22 (see reference). Figure 3 and Figure 4 (As shown).

[0083] See also Figure 2As shown, the tooling 100 may also include a threaded fastener 110, such as a screw, so that one end of the fastener 110 can abut against the outer wall of the first support 20 (such as on the first side 20b), and the other end passes through the first support 20 and engages with the threaded hole on the first mounting base 22, thereby achieving a detachable engagement between the first mounting base 22 and the first support 20.

[0084] Of course, in some other examples, the first mounting base 22 can also be detachably connected to the first support 20 by means of snap-fit ​​connection, hinge connection, etc.

[0085] There are various ways to detachably connect the second mounting base 32 and the first support 20. For example, the second mounting base 32 and the second support 30 can be detachably connected by the above-mentioned threaded connection, or the second mounting base 32 and the second support 30 can be detachably connected by snap-fit ​​connection, hinge connection, or other means.

[0086] It is understandable that the first support 20 and the second support 30 can have the same structure, and the first assembly 22 and the second assembly 32 can also have the same structure. Of course, in some other examples, the structures of the first support 20 and the second support 30, and the first assembly 22 and the second assembly 32 can also be different.

[0087] See also Figure 2 As shown, the first support 20 may include a first top surface 20a and a first side surface 20b, and the second support 30 may include a second top surface 30a and a second side surface 30b. Along the length of the guide rail 10, the first top surface 20a faces the second support 30, and the second top surface 30a faces the first support 20; that is, the first top surface 20a and the second top surface 30a are arranged opposite to each other.

[0088] The first side surface 20b can be arranged around the side of the first top surface 20a facing away from the second support 30, and the second side surface 30b can be arranged around the side of the second top surface 30a facing away from the first support 20.

[0089] The first mounting groove 21 on the first support 20 can extend to the first top surface 20a, forming an opening on the first top surface 20a. This opening can avoid the assembled gas spring 200, which helps to improve integration and reduce the size of the first support 20.

[0090] The first mounting groove 21 can also extend to the first side 20b, and an opening is also formed on the first side 20b, so that the first mounting base 22 can be pushed into the first mounting groove 21 from the side of the first support 20, which facilitates the assembly and disassembly of the first mounting base 22 and the first support 20.

[0091] Correspondingly, the second mounting groove 31 on the second support 30 can extend to the second top surface 30a, and the second mounting groove 31 can also extend to the second side surface 30b, forming openings on the second top surface 30a and the second side surface 30b. The second mounting base 32 can also be pushed into the second mounting groove 31 from the side of the second support 30, which facilitates the assembly and disassembly of the second mounting base 32 and the first support 20, and helps to improve integration and reduce the size of the second support 30.

[0092] See also Figure 2 , Figure 3 and Figure 4 As shown, the first mounting base 22 may include a third top surface 22a and a third side surface 22b, and the second mounting base 32 may include a fourth top surface 32a and a fourth side surface 32b. Along the length of the guide rail 10, the third top surface 22a faces the second mounting base 32, and the fourth top surface 32a faces the first mounting base 22, that is, the third top surface 22a and the fourth top surface 32a are arranged opposite to each other.

[0093] The third side 22b can be arranged around the third top surface 22a on the side facing away from the second mounting base 32, and the fourth side 32b can be arranged around the fourth top surface 32a on the side facing away from the first support 20.

[0094] The first positioning groove 221 on the first mounting base 22 extends at least to the third top surface 22a. For example, the first positioning groove 221 may only extend to the third top surface 22a, forming an opening on the third top surface 22a so that the gas spring 200 can be assembled into the first positioning groove 221 from the opening. This allows the first mounting base 22 to completely cover the end of the gas spring 200, improving the assembly firmness of the first mounting base 22 and the gas spring 200.

[0095] Of course, in some examples, the first positioning groove 221 can also extend to the third side 22b, and an opening is also formed on the third side 22b, so that the first mounting base 22 partially wraps the end of the gas spring 200. The end of the gas spring 200 can be pushed into the first positioning groove 221 from the side of the first mounting base 22, which facilitates the assembly of the gas spring 200 and the first mounting base 22 and improves the ease of assembly.

[0096] Correspondingly, the second positioning groove 321 on the second mounting base 32 extends at least to the fourth top surface 32a. For example, the second positioning groove 321 may extend only to the fourth top surface 32a, so that the second mounting base 32 completely covers the end of the gas spring 200, improving the assembly firmness. Alternatively, the second positioning groove 321 may also extend to the fourth side surface 32b, so that the second mounting base 32 partially covers the end of the gas spring 200, allowing the gas spring 200 to be pushed into the second positioning groove 321 from the side, achieving convenient assembly.

[0097] In the embodiments of this application, the second support 30 can move along the guide rail 10 in various ways. In some examples, the guide rail 10 and the second support 30 can move by means of a sliding rail and a slider. For example, the guide rail 10 can be a sliding rail, the second support 30 can be a slider, and the second support 30 can slide along the guide rail 10.

[0098] It is understandable that the tooling 100 may also include a locking mechanism, which can lock the sliding of the second support 30. That is, when the second support 30 slides to a predetermined position, the locking mechanism can fix the second support 30 relative to the guide rail 10 at that position, maintain the distance between the first support 20 and the second support 30, and thus maintain the compression length of the gas spring 200.

[0099] Alternatively, in some examples, the guide rail 10 and the second support 30 are moved by means of a lead screw thread engagement. For example, the guide rail 10 can be a lead screw with external threads on its outer wall, the external threads being helically distributed along the length of the guide rail 10.

[0100] See also Figure 2 As shown, the tooling 100 may also include a mating part 40, and the second support 30 may be fixed relative to the mating part 40. For example, the mating part 40 may be a nut, the second support 30 may be sleeved on the mating part 40, the mating part 40 may be sleeved on the guide rail 10, and the inner wall of the mating part 40 may have an internal thread that mates with the external thread of the guide rail 10.

[0101] The guide rail 10 is configured to be rotatable relative to the first support 20 and the second support 30. When the guide rail 10 rotates, the mating part 40 located on the guide rail 10 moves along the length direction of the guide rail 10 through the cooperation between the external thread and the internal thread, which in turn drives the second support 30 to move along the length direction of the guide rail 10.

[0102] Understandably, the second support 30 is mounted on the guide rail 10 via the mating part 40. Since the guide rail 10 and the mating part 40 are threaded together, the second support 30 does not move along the guide rail 10 when the guide rail 10 is not rotated. Thus, when the second support 30 moves to the predetermined position, the threaded engagement enables the second support 30 to self-lock, ensuring that the second support 30 is relatively fixed to the guide rail 10 at that position, maintaining the distance between the first support 20 and the second support 30, and thus maintaining the compression length of the gas spring 200.

[0103] For easier operation of the drive guide 10, please refer to [reference needed]. Figure 2As shown, the tooling 100 may also include an adjusting member 50, which may be located on the side of the first support facing away from the second support, to facilitate operation of the adjusting member 50. The adjusting member 50 may be fixed relative to the guide rail 10, and rotating the adjusting member 50 may drive the guide rail 10 to rotate.

[0104] For example, the adjusting member 50 can be an adjusting nut, which can be sleeved on the guide rail 10 and fixed to the guide rail 10. The adjusting nut can be rotated by a wrench or other tools, so that the second support 30 can move along the guide rail 10, thereby compressing or resetting the gas spring 200.

[0105] For example, mounting holes can be made in the guide rail component 10 and the adjusting nut. Screws, pins, or other fasteners can be passed through the mounting holes in the adjusting nut and then fixed to the guide rail component 10, thus securing the guide rail component 10 and the adjusting nut. Alternatively, the guide rail component 10 and the adjusting nut can also be assembled together by welding, bonding, or snap-fit ​​connections.

[0106] Alternatively, the adjusting member 50 can be other structural components that facilitate rotational operation. For example, the adjusting member 50 can also be a columnar handle, which can be arranged perpendicularly to the guide rail 10. Rotating the columnar handle can drive the guide rail 10 to rotate, thereby allowing the second support 30 to move along the guide rail 10.

[0107] For example, the adjusting element 50 can also be a knob, etc. Rotating the adjusting element 50 can move the second support 30.

[0108] Taking the adjusting component 50 as an example, the method of installing and removing the gas spring 200 using the tool 100 is explained. When installing the gas spring 200, the adjusting component 50 can be rotated using a wrench or similar tool to move the second support 30 along its length. The linear distance between the first support 20 and the second support 30 in the length direction is greater than the distance between the two ends of the gas spring 200. One end of the gas spring 200 is fixed in the first mounting base 22 of the first support 20. The adjusting component 50 is then rotated in the opposite direction to move the second support 30 toward the first support 20, shortening the distance between the first support 20 and the second support 30. When the distance between the two supports is equal to the distance between the two ends of the gas spring 200, the other end of the gas spring 200 is fixed in the second mounting base 32 of the second support 30.

[0109] Continue rotating the adjusting member 50 to move the second support 30 toward the first support 20, thereby compressing the gas spring 200. It can be understood that one rotation of the adjusting member 50 corresponds to one pitch movement of the second support 30, allowing for precise displacement of the second support 30. After compressing the gas spring 200 to the predetermined length, fix both ends of the gas spring 200 to the interface of the equipment where it needs to be installed (such as the cover and housing of a semiconductor manufacturing equipment). Then, rotate the adjusting member 50 in the opposite direction to increase the distance between the first support 20 and the second support 30, thereby separating the tooling 100 from the gas spring 200, completing the installation of the gas spring 200.

[0110] When disassembling the gas spring 200, the distance between the two supports can be equalized to the distance between the two ends of the gas spring 200 by rotating the adjusting component 50 with a wrench or similar tool. The two ends of the gas spring 200 are then placed into the first mounting base 22 and the second mounting base 32 respectively. The connection between the gas spring 200 and the equipment is then disassembled, and the gas spring 200 is removed from the equipment. Rotating the adjusting component 50 moves the second support 30, causing the gas spring 200 to return to its original length. Continuing to rotate the adjusting component 50, the gas spring 200 is then removed from the tooling 100, completing the disassembly operation. The installation and disassembly process is safe, efficient, and labor-saving.

[0111] See also Figure 2 As shown, the tooling 100 also includes a guide member 60, the length direction of which can be consistent with the length direction of the guide rail member 10, such as both being guide members. Figure 2 In the x-direction, the guide member 60 and the guide rail member 10 can be set at intervals.

[0112] The first support 20 is fixed relative to the guide member 60, and the second support 30 can slide along the length direction of the guide member 60. The guide member 60 can guide and limit the movement of the second support 30, and the guide rail 10 can also guide and limit the movement of the second support 30, so that the second support 30 moves linearly along the length direction and does not rotate around the length direction, thereby improving the stability and reliability of the compression or reset operation of the gas spring 200.

[0113] The number of guide members 60 can be one, or the number of guide members 60 can be at least two. Of the at least two guide members 60, the distribution direction of one guide member 60 and the guide rail member 10 intersects at least the distribution direction of the other guide member 60 and the guide rail member 10. The length direction of the guide member 60 is parallel to the length direction of the guide rail member 10, and the guide members 60 and the guide rail member 10 are spaced apart. The distribution direction of the guide members 60 and the guide rail member 10 can be consistent with the direction of the line connecting the guide members 60 and the guide rail member 10. This line can be a straight line connecting the guide member 60 and the guide rail member 10 at both ends, and perpendicular to the length directions of both the guide member 60 and the guide rail member 10.

[0114] By ensuring that the distribution direction of one of the guide members 60 and the guide rail member 10 intersects with the distribution direction of the other guide member 60 and the guide rail member 10, and thus arranges at least two guide members 60 and the guide rail member 10 in a triangular distribution, the stability and support for the movement of the second support 30 can be further improved, and the stability and reliability of the tooling 100 can be further improved during the compression or reset of the gas spring 200.

[0115] The second support 30 is driven and guided by the spaced guide members 60 and guide rail members 10. Both the guide members 60 and guide rail members 10 can be rod-shaped structures, which helps to make the tooling 100 lightweight and improve its portability.

[0116] In this design, there can be two guide components 60, which ensures good stability and reliability while achieving a lightweight tooling unit 100. Of course, in some other examples, the number of guide components 60 can also be other positive integers.

[0117] For example, the guide member 60 can be set relatively far away from the first mounting groove 21 (second mounting groove 31) and the first mounting base 22 (second mounting base 32), which on the one hand facilitates the avoidance of the gas spring 200, and on the other hand helps to improve the strength of the first support 20 and the second support 30, and improves the reliability of the entire tooling 100.

[0118] A limiting member (not shown in the figure) may be provided at the end of at least one of the guide member 60 and the guide rail member 10. The limiting member is located on the side of the second support 30 facing away from the first support 20. For example, the limiting member may be a limiting snap ring. A groove may be formed on one end of the guide member 60 and the guide rail member 10. The limiting snap ring may be disposed in the groove. The limiting snap ring shall limit the second support 30 and prevent the movable second support 30 from disengaging from the guide rail member 10.

[0119] Figure 5 for Figure 2 A magnified view of part A in the middle.

[0120] See Figure 5 As shown, the tooling may also include a first bearing 70, which may include a sleeve and rolling elements (not shown in the figure), with the rolling elements tumbling within the sleeve. For example, the first bearing 70 may be a linear bearing, and the axis of the first bearing 70 may be the same as the length direction of the guide member 60. The sleeve may be a cylindrical housing, and the rolling elements are assembled within the sleeve and can roll within the sleeve.

[0121] The sleeve can be fitted onto the guide member 60, and the rolling elements inside the sleeve will contact the outer wall of the guide member 60. This allows the first bearing 70 to roll and contact the guide member 60 through the rolling elements, so that the first bearing 70 can slide along the length of the guide member 60.

[0122] The second support 30 is fixed to the sleeve. For example, the second support 30 can be sleeved onto the sleeve. The second support 30 can also have a through hole (not shown in the figure) that extends through the second support 30 in the length direction, allowing the sleeve of the first bearing 70 to be fixed within the through hole, thus achieving a fixed assembly of the second support 30 and the sleeve of the first bearing 70. This allows the second support 30 to slide along the guide member 60 via the first bearing 70, improving the smoothness of the second support 30's sliding on the guide member 60 and enhancing the user experience.

[0123] It is understandable that when there are multiple guide members 60, the number of through holes and first bearings 70 on the second support 30 is the same as the number of guide members 60, with one guide member 60 corresponding to one through hole and one first bearing 70.

[0124] See also Figure 5 As shown, the tooling may also include a handle 90, which can be fixed to the second side of the second support 30. For example, a mounting hole may be provided on the second side, through which the handle 90 can be fixed to the second support 30. The handle 90 facilitates the handling or operation of the entire tooling, thus facilitating construction.

[0125] Figure 6 for Figure 2 A magnified view of part B in the middle section.

[0126] In this embodiment, the adjusting member 50 is rotatably disposed on the side of the first support 20 facing away from the second support 30 (in conjunction with...). Figure 2 As shown, the guide rail 10 can pass through the first support 20 and be fixed to the adjusting member 50. This places the adjusting member 50 on the outside of the first support 20, that is, on one end of the entire tooling, making it easy to rotate the adjusting member 50 and facilitate operation.

[0127] For example, the first support 20 may be provided with multiple mounting holes (not shown in the figure), which may be through holes or threaded holes. The guide rail 10 may pass through some of the mounting holes and be fixed relative to the adjusting member 50. The guide member 60 may also be fixed relative to the second support 30 through the mounting holes.

[0128] See Figure 6 As shown, the tooling may also include a second bearing 80, which is located on the side of the first support 20 facing away from the second support 30 (in conjunction with...). Figure 2 (As shown).

[0129] The second bearing 80 may include a housing ring, rolling elements, and a shaft ring (not shown in the figure) located on one side of the housing ring. The rolling elements are rotatably disposed between the housing ring and the shaft ring, so that the shaft ring can be rotated relative to the housing ring by the rolling elements.

[0130] The second bearing 80 can be sleeved on the guide rail 10 and is located between the first support 20 and the adjusting member 50. The bearing ring can be fixed relative to the side of the first support 20 facing the adjusting member 50, and the bearing shaft can be fixed relative to the adjusting member 50. This allows the adjusting member 50 to rotate relative to the first support 20 via the second bearing 80, thereby enabling the adjusting member 50 to drive the guide rail 10 to rotate relative to the first support 20 and the second support 30. This improves the smoothness of the rotation of the adjusting member 50, thereby improving the smoothness of the sliding of the second support 30 and enhancing the user experience. In addition, it can also reduce or avoid damage to the first support 20 caused by friction between the rotating adjusting member 50 and the first support 20.

[0131] The adjusting component 50 can be fixed to the shaft ring, and the first support 20 can be fixed to the seat ring by means of threaded connection, welding connection, adhesive connection, snap-fit ​​connection, etc.

[0132] A handle 90 can also be provided on the first support 20. For example, a mounting hole can be provided on the third side of the first support 20. The handle 90 can be fixed on the first support 20 through the mounting hole to facilitate construction.

[0133] In this embodiment of the application, the guide rail 10 may include a main body 11 and two end portions 12 (see reference 10). Figure 2 As shown, along the length of the guide rail 10, the two ends 12 can be located at the two ends of the main body 11 respectively. In order to facilitate the assembly of the guide rail 10 with the first support 20, the second support 30 and the second bearing 80, the diameters of the two ends 12 can be smaller than the diameter of the main body 11 respectively.

[0134] Correspondingly, the guide member 60 may also have a main body 11 and two ends 12. The diameters of the two ends 12 of the guide member 60 may be smaller than the diameter of the main body 11, which facilitates the assembly of the guide member 60 with the first support 20, the second support 30 and the first bearing 70.
