[0002] In the aerospace industry, component performance testing is often required under high load, high speed, and high frequency conditions. To ensure accuracy and the safety of both the equipment and the test piece during testing, reliable linear guide structures must be employed to provide stable motion support.

[0003] Currently, commonly used guide structures include single-rail and dual-rail linear guide structures. Although these structures can achieve basic linear guidance, because the load force and the guide rail are not in the same plane, there is a height difference.

Another commonly used guide structure is the four-guide rod guide structure. In theory, it can handle high load and high speed working conditions, but this structure requires extremely high processing and installation precision, and the guide stroke is small, which is prone to jamming or blocking during use, affecting the smoothness and reliability of the guide.

[0026] One or more technical solutions provided in this application have at least the following technical effects or advantages:

[0027] The mounting assembly, consisting of a first mounting block and a second mounting block, secures and supports the guide shaft assembly and maintains the stability of the entire guide mechanism. The symmetrical arrangement of the first and second mounting blocks ensures that the guide shaft and the load transmission mechanism are aligned horizontally, preventing deviations caused by asymmetrical arrangements. The guide shaft assembly, consisting of a first guide shaft and a second guide shaft, is mounted on the first and second mounting blocks, respectively, guiding the load transmission mechanism in a linear motion, providing a precise linear motion path. The guide shafts and load transmission mechanism are coupled together via an auxiliary assembly (graphite copper sleeves) to ensure smooth movement under high loads. The dual-guide rod design, with the guide shafts located on either side of the load transmission mechanism, effectively eliminates torque issues associated with traditional single-rail designs, prevents guide rail warping or structural deformation, and enhances the structure's torsional rigidity. The load transmission mechanism's first end is sheathed on the first guide shaft, and its second end is sheathed on the second guide shaft. The load transmission mechanism carries the external load and moves along the guide shafts. Driven by a pulling mechanism, the load transmission mechanism can achieve high-frequency, high-speed reciprocating motion. The load transmission mechanism is supported at both ends by guide shafts, ensuring smooth movement under high loads, preventing structural deflection or deformation, and reducing vibration and friction during the guiding process. Auxiliary kits are installed at both ends of the load transmission mechanism and over the guide shaft assembly to reduce friction and ensure smooth sliding of the load transmission mechanism along the guide shaft. The self-lubricating properties of the graphite copper sleeve significantly reduce friction as the load transmission mechanism slides on the guide shaft, ensuring smooth and precise operation of the system. Furthermore, the self-lubricating material effectively extends the life of the guide system, reduces maintenance, and improves equipment reliability. A pulling mechanism is installed through a pre-set position in the load transmission mechanism to transmit external force, pushing or pulling the load transmission mechanism along the guide shaft for linear motion. The pulling mechanism is located in the center of the load transmission mechanism, ensuring even force distribution. The pulling mechanism is aligned with the load transmission mechanism and guide shaft assembly, preventing structural deformation or unstable movement caused by asymmetrical force. This pulling mechanism enables the load transmission mechanism to operate at high speeds under external force, meeting the requirements of high-frequency linear motion. The anti-collision bracket assembly includes a first anti-collision bracket and a second anti-collision bracket, which are respectively installed on the first mounting seat and the second mounting seat, and an anti-collision rod assembly is installed thereon. The anti-collision rod assembly is connected by threads, which facilitates the adjustment of the position of the anti-collision limit. The anti-collision assemblies are deployed in pairs on both sides of the load transmission mechanism, and are used to provide buffering protection when the load transmission mechanism moves to the extreme position to prevent the transmission mechanism from exceeding the specified stroke. The anti-collision assembly contacts the anti-collision rod and plays a role in limiting and preventing collisions, effectively preventing the load transmission mechanism from rushing out of the guide range when running at high speed, and protecting the guide mechanism and external equipment from damage. The anti-collision assembly made of flexible material provides additional buffering, reduces the impact force, and extends the service life of the guide mechanism. The platform is used to install the entire guide mechanism, including the mounting seat assembly and the anti-collision bracket assembly.The platform serves as a base, providing stable support for the guide mechanism and connecting the guide mechanism to the test bench or other equipment.

[0028] To sum up, the various components of the bidirectional double-guide rod linear guide mechanism provided by this application cooperate with each other and work together to solve the torque problem of the unidirectional guide rail, ensure the guiding stability under high load, high speed and high frequency conditions, and improve the reliability and applicability of the guiding mechanism.

DETAILED DESCRIPTION

[0035] The embodiment of the present application provides a bidirectional double-guide rod linear guide mechanism to solve the technical problem that the existing guide mechanism is prone to structural deformation and jamming when facing harsh conditions such as large loads, high speeds, and high frequencies, resulting in insufficient guiding accuracy, thereby achieving the technical effect of improving the stability and smoothness of the guide.

[0036] like Figure 1 As shown, an embodiment of the present application provides a bidirectional double-guide rod linear guide mechanism, which mainly includes a mounting seat assembly 10, a guide shaft assembly 20, a load transmission mechanism 30, an auxiliary kit 40 and a pulling mechanism 50.

[0037] like Figure 2 As shown, the mounting seat assembly 10 includes a first mounting seat and a second mounting seat, and the first mounting seat and the second mounting seat are symmetrical to each other along a first preset axial plane.

[0038] Furthermore, the first mounting seat or the second mounting seat includes a base 11 and a connecting plate; the connecting plate includes a first connecting plate 12 and a second connecting plate 13; the first connecting plate 12 is installed on the first end surface of the base 11; the second connecting plate 13 is installed on the second end surface of the base 11; wherein, the first connecting plate 12 is provided with a first hole, and the second connecting plate 13 is provided with a second hole, and the first hole and the second hole are used to install the guide shaft assembly 20.

[0039] Specifically, the main function of the mounting seat is to provide a stable mounting position for the guide shaft and to provide support for the load transmission mechanism 30 so that it can perform smooth linear motion on the guide shaft. The first mounting seat and the second mounting seat are symmetrically arranged on both sides of the linear guide mechanism along the preset axial plane to form a symmetrical structure to ensure that the guide shaft and the load transmission mechanism 30 are on the same horizontal plane. Among them, the first preset axial plane is a reference plane defined in advance in the design, which is used to determine the installation position and symmetry relationship of each component. This symmetrical design helps to balance the load, avoid structural distortion or deformation caused by unilateral force, ensure the stability of the entire system, reduce the possible eccentric torque, and improve the torsional rigidity of the structure. The base 11 is a welded structure and is the main load-bearing component of the mounting seat. It is used to support other components (such as the connecting plate and the guide shaft assembly 20), providing a stable foundation to prevent the guide shaft from displacing or shaking during movement. The base 11 is usually fixed to the platform by bolts, and its precise positioning on the platform is ensured by the positioning pin holes on the bottom surface.

[0040] Each of the two ends (the first end face and the second end face) of each base 11 is respectively connected to a connecting plate, namely a first connecting plate 12 and a second connecting plate 13. Each connecting plate is provided with a hole, namely a first hole and a second hole. The two holes are concentric holes. One end of the guide shaft is installed in the first hole and the other end is installed in the second hole. The guide shaft is fixed to the mounting seat assembly 10 through these two holes, providing precise axis positioning, ensuring the coaxiality of the guide system, and reducing the deviation or distortion of the guide shaft when the load transmission mechanism 30 moves. At the same time, it ensures the smoothness of the load transmission mechanism 30 under high load and high-speed movement. The connecting plate forms an overall stable mounting seat assembly 10 through a firm connection with the base 11.

[0041] Due to the design of the locating pin holes in the mounting base assembly 10, the coaxiality requirements for the mounting holes and the machining accuracy of the base 11 are not very high during the manufacturing process, reducing the manufacturing difficulty. Generally, a level 7 accuracy can be achieved and adjustments can be made during assembly. During installation, one base 11 is fixed with a locating pin and the fixing screws are tightened. By fine-tuning the other base 11, the load transmission mechanism 30 can slide freely on the guide shaft. Then, the screws are tightened to fix the other base 11, achieving smooth sliding.

[0042] The guide shaft assembly 20 includes a first guide shaft and a second guide shaft, wherein the first guide shaft is mounted on the first mounting seat; and a second guide shaft, wherein the second guide shaft is mounted on the second mounting seat, and the first guide shaft and the second guide shaft are symmetrical to each other along the first preset axis plane.

[0043] Specifically, the guide shaft assembly 20 consists of two guide shafts, a first guide shaft and a second guide shaft, which provide the motion path for the load transmission mechanism 30. The first guide shaft is mounted on a first mounting base, and the second guide shaft is mounted on a second mounting base. Each guide shaft guides and supports the load on one side, enabling the load transmission mechanism 30 to slide smoothly along the guide shafts. The two guide shafts are symmetrically arranged, forming a dual-guide shaft system. This enhances the stability and torsional resistance of the entire mechanism, ensuring smooth movement of the load transmission mechanism 30 while avoiding the motion deviation and instability that may occur in a single-axis system. This makes it more adaptable to high-load, high-speed working environments.

[0044] The load transmission mechanism 30 has a first end sleeved on the first guide shaft, and a second end sleeved on the second guide shaft.

[0045] Specifically, the load transmission mechanism 30 is a core component used to carry external loads and move on the guide shaft. The two ends of the load transmission mechanism 30 are respectively connected to the two guide shafts. Through the guidance of the guide shafts, the load transmission mechanism 30 drives the externally applied load to perform smooth linear motion on the parallel guide shafts.

[0046] In this mechanism, the first mounting seat and the second mounting seat are arranged symmetrically along the first preset axial plane, and the guide shaft and the load transmission mechanism 30 are also arranged along the axial plane. This ensures that the load does not tilt or shift during movement, and at the same time, evenly applies force on both sides to avoid deformation of the mechanism due to uneven force on one side.

[0047] The auxiliary kit 40 is installed on both sides of the first end of the load transmission mechanism 30 and both sides of the second end of the load transmission mechanism 30 , and is sleeved on the guide shaft assembly 20 .

[0048] Furthermore, the auxiliary kit 40 is a graphite copper sleeve.

[0049] Specifically, the auxiliary kit 40 is an additional auxiliary component installed at each end of the load transmission mechanism 30, typically a sliding element that fits over a guide shaft. The auxiliary kit 40 is mechanically attached to each end of the load transmission mechanism 30, fitting over the guide shaft. Because it is positioned between the guide shaft and the load transmission mechanism 30, it effectively reduces friction between the two during movement, ensuring smooth and stable sliding of the load transmission mechanism 30 along the guide shaft. This also reduces wear between the guide shaft and the load transmission mechanism 30.

[0050] In a specific embodiment, the auxiliary assembly 40 utilizes graphite copper sleeves, including but not limited to embedded graphite-tin bronze alloy self-lubricating sleeves, self-lubricating tin bronze sleeves, self-lubricating aluminum bronze sleeves, oil-injected sliding sleeves, and self-lubricating sleeves with outer steel and inner copper. These sleeves utilize the natural lubricating properties of graphite to provide continuous lubrication in high-load and high-frequency applications, reducing frictional resistance and temperature rise. Their self-lubricating properties enable the entire mechanism to maintain stability even at high speeds. The copper matrix provides excellent strength and durability for the entire assembly, while the graphite particles act as a solid lubricant, reducing friction during sliding and minimizing wear on the guide shaft, thereby effectively extending the service life of the entire guide mechanism and reducing maintenance requirements and downtime.

[0051] The pulling mechanism 50 is penetrated and arranged at a preset position of the load transmission mechanism 30 , wherein the preset position is located between the first end of the load transmission mechanism 30 and the second end of the load transmission mechanism 30 , and the pulling mechanism 50 and the guide shaft assembly 20 are in the same horizontal plane.

[0052] Specifically, the pulling mechanism 50 is the core driving element of the entire guide mechanism. It applies a pulling or pushing force to move the load transmission mechanism 30 along the guide shaft, precisely controlling the movement of the load transmission mechanism 30. The preset position refers to the specific location where the pulling mechanism 50 is installed on the load transmission mechanism 30. This location is located between the two ends of the load transmission mechanism 30. This location is precisely designed and adjusted to ensure uniform force distribution during pulling, transmitting force to both ends of the load transmission mechanism 30, thereby preventing tilting or increased resistance to movement due to uneven force.

[0053] During operation, the pulling mechanism 50 generates a pulling force mechanically or electrically, applying this force to the center of the load transmission mechanism 30. Because the pulling mechanism 50 is mounted at a predetermined position on the load transmission mechanism 30, it evenly transmits force to both ends of the load transmission mechanism 30, causing it to slide on the guide shaft assembly 20. The pulling mechanism 50 and the guide shaft assembly 20 are maintained on the same horizontal plane, ensuring that the pulling force is transmitted along the guide shaft without generating any excess vertical or lateral force components, thereby ensuring smooth linear motion of the load transmission mechanism 30.

[0054] Furthermore, the mechanism described in the embodiment of the present application also includes:

[0055] Anti-collision components are arranged in pairs on both sides of the load transmission mechanism 30 , and the anti-collision components are located between the preset position and the two ends of the load transmission mechanism 30 .

[0056] The anti-collision bracket assembly 60 includes a first anti-collision bracket and a second anti-collision bracket, the first anti-collision bracket is installed with a first anti-collision rod assembly arranged opposite to the anti-collision assembly in the same horizontal plane; the second anti-collision bracket is installed with a second anti-collision rod assembly arranged opposite to the anti-collision assembly in the same horizontal plane; wherein, the first anti-collision bracket and the second anti-collision bracket are symmetrical to each other along the first preset axis plane, the first anti-collision bracket is deployed on the first side of the first mounting seat, and the second anti-collision bracket is deployed on the second side of the second mounting seat, and the first side and the second side are in a relative relationship.

[0057] Furthermore, there are two pairs of anti-collision components.

[0058] Furthermore, the anti-collision component is made of flexible material.

[0059] Specifically, the anti-collision assembly is a structure installed on both sides of the load transmission mechanism 30 to provide position limiting protection when the load transmission mechanism 30 moves. Anti-collision assemblies are typically used in pairs, one located between a preset position and the other end of the load transmission mechanism 30. When the load transmission mechanism 30 slides on the guide shaft, the anti-collision assembly always maintains a consistent trajectory with the anti-collision bar 62. When the load transmission mechanism 30 reaches its limit position, the anti-collision assembly contacts the anti-collision bar 62, forming a physical limit to prevent further movement, thereby providing a buffering and shock-absorbing effect, preventing damage to the guide mechanism and external load caused by rigid impact.

[0060] The anti-collision component can be made of various flexible materials, including, but not limited to, polyurethane and rubber. These materials effectively absorb impact energy, reducing the collision force between the load transmission mechanism 30 and the anti-collision bar 62, preventing damage or premature wear, and effectively extending the service life of the guide mechanism. Furthermore, these flexible materials enhance the safety of the entire mechanism during operation, enabling it to accommodate high-frequency motion conditions, expand the scope of application of the guide mechanism, and flexibly address various guided motion requirements.

[0061] The anti-collision bracket assembly 60 is a support structure mounted on the mounting base assembly 10. It includes first and second anti-collision brackets, mounted on the sides of the first and second mounting bases, respectively, and arranged symmetrically along a first predetermined axis. The anti-collision brackets secure the anti-collision bar 62 and form a symmetrical retaining structure with the anti-collision assembly. When the load transmission mechanism 30 moves along the guide axis, the anti-collision bracket assembly 60, through the anti-collision bar 62, provides positional protection for the load transmission mechanism 30.

[0062] The first and second anti-collision brackets are both equipped with a rod-shaped structure, namely the first anti-collision bar assembly and the second anti-collision bar assembly. The first anti-collision bar assembly and the second anti-collision bar assembly are respectively located on both sides of the load transmission mechanism 30 and are arranged opposite to the anti-collision assembly. The two are at the same height to ensure that they can accurately contact when the load transmission mechanism 30 moves to the limit, thereby playing a limiting role. When the load transmission mechanism 30 moves to the limit position, the anti-collision bar assembly contacts the anti-collision assembly and provides physical limitation to prevent the load transmission mechanism 30 from continuing to move, thereby playing a protective role. The anti-collision bar 62 is provided with a thread to adjust the limit position.

[0063] Furthermore, the first anti-collision bracket is assembled and formed by multiple mechanisms or is integrally formed, and the second anti-collision bracket is assembled and formed by multiple mechanisms or is integrally formed.

[0064] Specifically, there are two options for manufacturing the first anti-collision bracket and the second anti-collision bracket. They can be assembled and formed by multiple mechanisms, or manufactured by integral molding.

[0065] like Figure 3 As shown, the anti-collision bracket structure is one-piece formed. The entire anti-collision bracket is made as a whole through casting or other manufacturing processes, which has higher structural strength and stability, and reduces potential problems caused by assembly errors or loose connections.

[0066] like Figure 4 The figure below shows the components of the assembled anti-collision bracket structure. Each anti-collision bracket is composed of two independent left and right components that are mechanically assembled together (such as bolts or welding) to form the final anti-collision bracket structure. This assembly design allows for flexible adjustment in different application scenarios and facilitates repair and replacement of components, but the structural strength requires additional reinforcement.

[0067] The manufacturing method of the first and second anti-collision brackets can be selected according to the actual application requirements. If high precision and high strength are required, one-piece molding can be selected; if flexibility and adjustability are emphasized, assembly molding can be used.

[0068] Furthermore, the first anti-collision bracket or the second anti-collision bracket also includes: a key slot, which is opened on the bottom surface of the first anti-collision bracket or the second anti-collision bracket; and a positioning key 61, which is installed in the key slot.

[0069] Specifically, the anti-collision bracket also includes two key components: a keyway and a positioning key 61. The keyway is a groove-shaped structure cut into the bottom surface of the anti-collision bracket, which is used to accommodate the positioning key 61. The positioning key 61 is usually a long metal piece installed in the keyway to prevent the anti-collision bracket from moving relative to its mounting surface.

[0070] During installation, the positioning key 61 works in conjunction with the keyway to provide positioning and alignment, ensuring the anti-collision bracket remains accurately positioned during installation. During operation of the guide mechanism, the keyway and positioning key 61 cooperate to prevent the anti-collision bracket from shifting or rotating when subjected to external forces, thereby maintaining the stability of the anti-collision bracket throughout the entire operation of the guide mechanism.

[0071] Furthermore, the mechanism described in the embodiment of the present application also includes:

[0072] A platform, the mounting seat assembly 10 and the anti-collision bracket assembly 60 are installed on the platform.

[0073] Furthermore, the mounting seat assembly 10 and the anti-collision bracket assembly 60 are mounted on the platform by bolts.

[0074] Specifically, the platform is the foundational mounting surface for the entire mechanism, typically a planar structure used to secure the mounting base assembly 10 and the anti-collision bracket assembly 60, providing a supporting foundation for the entire guide mechanism. The mounting base assembly 10 and the anti-collision bracket assembly 60 can be bolted to the platform to prevent them from shifting due to the movement of the load transmission mechanism 30, thereby maintaining the rigidity and stability of the guide mechanism.

[0075] In summary, the bidirectional dual-guide rod linear guide mechanism provided by the embodiments of the present application has the following technical effects:

[0076] The mounting base assembly 10 includes a first mounting base and a second mounting base, which are used to secure and support the guide shaft assembly 20 and maintain the stability of the entire guide mechanism. The first and second mounting bases are symmetrically arranged to ensure that the guide shaft and the load transmission mechanism 30 are on the same horizontal plane, avoiding deviation caused by asymmetrical arrangement. The guide shaft assembly 20 includes a first guide shaft and a second guide shaft, mounted on the first and second mounting bases, respectively, to guide the load transmission mechanism 30 in a linear direction, providing a precise linear motion path. The guide shafts and the load transmission mechanism 30 are mated together via an auxiliary sleeve 40 (graphite copper sleeve), ensuring smooth movement under high loads. The dual-guide rod design, with the guide shafts located on both sides of the load transmission mechanism 30, effectively eliminates the torque issues associated with traditional single-rail designs, prevents guide rail tilting or structural deformation, and enhances the torsional rigidity of the structure. The first end of the load transmission mechanism 30 is sleeved onto the first guide shaft, and the second end is sleeved onto the second guide shaft, for carrying external loads and moving along the guide shafts. Driven by the pulling mechanism 50, the load transmission mechanism 30 can perform high-frequency, high-speed reciprocating motion. The load transmission mechanism 30 is supported at both ends by guide shafts, enabling smooth movement under high loads, preventing structural deflection or deformation, and reducing vibration and friction during the guiding process. An auxiliary assembly 40 is installed at both ends of the load transmission mechanism 30 and fits over the guide shaft assembly 20, reducing friction and ensuring that the load transmission mechanism 30 slides smoothly along the guide shaft. The self-lubricating properties of the graphite copper sleeve significantly reduce friction as the load transmission mechanism 30 slides on the guide shaft, ensuring smooth and precise operation of the system. Furthermore, the self-lubricating material effectively extends the service life of the guide system, reduces maintenance frequency, and improves equipment reliability. A pulling mechanism 50 is installed through a pre-set position on the load transmission mechanism 30 to transmit external power, pushing or pulling the load transmission mechanism 30 for linear motion along the guide shaft. The pulling mechanism 50 is located in the middle of the load transmission mechanism 30, ensuring even force distribution. The pulling mechanism 50 is aligned with the load transmission mechanism 30 and the guide shaft assembly 20, preventing structural deformation or unstable movement caused by asymmetric forces. Through the action of the pulling mechanism 50, the load transmission mechanism 30 can run at high speed under the drive of external force, meeting the needs of high-frequency linear motion. The anti-collision bracket assembly 60 includes a first anti-collision bracket and a second anti-collision bracket, which are respectively mounted on the first mounting seat and the second mounting seat, on which an anti-collision rod assembly is mounted. The anti-collision rod assembly is connected by a threaded connection, which is convenient for adjusting the position of the anti-collision limit. The anti-collision assemblies are deployed in pairs on both sides of the load transmission mechanism 30, and are used to provide buffer protection when the load transmission mechanism 30 moves to the extreme position, preventing the transmission mechanism from exceeding the specified stroke. The anti-collision assembly contacts the anti-collision rod 62, which plays a role of limiting and anti-collision, effectively preventing the load transmission mechanism 30 from rushing out of the guide range when running at high speed, and protecting the guide mechanism and external equipment from damage.The flexible material's anti-collision assembly provides additional cushioning, reducing impact forces and extending the life of the guide mechanism. The platform is used to mount the entire guide mechanism, including the mounting base assembly 10 and the anti-collision bracket assembly 60. Serving as a base, the platform provides stable support for the guide mechanism and connects it to a test bench or other equipment.

[0077] Overall, the various components of a bidirectional double-guide rod linear guide mechanism provided by the embodiment of the present application cooperate with each other and work together to solve the torque problem of the unidirectional guide rail, ensure the guiding stability under high load, high speed and high frequency conditions, and improve the reliability and applicability of the guiding mechanism.
