Description

Technical Field

[0001] The invention relates to a one-way connector mechanism used for connecting output ends of various mechanical equipment. Background Art

[0002] One-way connectors are used to transmit displacement or force in one direction without causing displacement or force in the other five directions. In the field of astronomical instruments, force actuators, as devices that generate unidirectional force output, are key technical components for achieving high-precision optical imaging adjustment. Force actuators are often used in astronomical telescope mirrors or other precision optical mirrors as actuators to actively correct or change the mirror's surface shape. They are used to precisely adjust the telescope's mirror shape and correct or compensate for minor deformations in optical components to ensure excellent image quality.

[0003] The output end of the force actuator requires an appropriate connection mechanism to apply its output force to the optical mirror surface (usually the back surface), without introducing forces or torques in other directions. Traditionally, force actuators often use elastic rods or spherical bearings as the output force connection structure. The former requires careful design of the elastic rod's flexibility, but has high requirements for installation and positioning accuracy, is difficult to adjust, and always introduces a certain amount of force or torque in other directions. The latter spherical bearing connection structure also requires high installation and positioning accuracy and always involves friction. The most classic one-way joint in traditional industry is the James coupler used to connect train cars. The James coupler is a fast and reliable connection, but its structure is complex, and the pins on both ends must be pulled apart during separation. Therefore, these traditional joints have obvious limitations in practical applications and cannot meet the requirements of high-precision optical active support. Summary of the Invention

[0004] To address the aforementioned issues with existing technologies, the present invention provides a quickly assembled and disassembled one-way connector. This connector design facilitates quick installation and removal, significantly improving equipment maintenance efficiency and flexibility. This is particularly true in work environments where output accuracy and stability are critical, such as when connecting to a one-way precision force actuator.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A one-way joint that can be quickly assembled and disassembled includes a U-shaped connector, a fork-shaped connector, an adjustment plate, an external pin, an internal pin and an intermediate pin. The U-shaped connector includes a U-shaped plate and a first connection end. The internal pin is installed on the U-shaped connector through the U-shaped plate. The adjustment plate is installed on the U-shaped plate. The external pin is installed parallel to the internal pin through the adjustment plate. The fork-shaped connector includes a fork plate and a second connection end. The intermediate pin is installed vertically between the external pin and the internal pin through the fork plate.

[0007] Furthermore, a screw hole is provided on the U-shaped plate inside the internal pin shaft, and a through hole is provided on the adjustment plate inside the external pin shaft. The adjustment screw passes through the through hole and the screw hole in sequence to connect the adjustment plate to the U-shaped plate.

[0008] Furthermore, by adjusting the position of the adjustment plate through the adjustment screw, the external pin shaft is driven to make a slight position adjustment, thereby controlling the parallelism between the external pin shaft and the internal pin shaft, achieving a nearly zero gap between the external pin shaft, the internal pin shaft and the intermediate pin shaft, and allowing the intermediate pin shaft and the fork-shaped connector to act as a whole and freely realize the other five degrees of freedom except axial movement.

[0009] Furthermore, the first connection end is firmly connected to the output end of the force actuator.

[0010] Furthermore, the second connecting end is connected to the optical mirror.

[0011] Furthermore, a connecting seat is fixedly connected to the non-working surface of the optical mirror, a plurality of screw holes are provided on the outer periphery of the connecting seat, a V-shaped groove is provided on the outer circular surface of the second connecting end of the fork-shaped connecting head, and the second connecting end is arranged in the connecting seat, and the fork-shaped connecting head is fixed to the connecting seat by screwing a fastening screw into the screw hole.

[0012] Furthermore, when connecting, the second connecting end of the fork-shaped connector is inserted into the connecting seat, and the fastening screw is screwed in so that the conical surface of the end of the fastening screw fits and fastens with the V-shaped groove of the second connecting end of the fork-shaped connector; when disassembling, the fastening screw is loosened and the second connecting end of the fork-shaped connector is pulled out of the connecting seat.

[0013] Furthermore, the one-way joint is used to transmit a one-way force without introducing forces or moments in other directions.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The one-way joint of the present invention is used to guide and connect the unidirectional force output by the force actuator, while remaining unconstrained in the other five degrees of freedom, that is, it does not cause other interfering forces and torques, and has a quick-connect joint for easy assembly and disassembly. The structure of the external pin, internal pin, and intermediate pin allows the upper fork-shaped connector to rotate a certain amount about the X-axis, Y-axis, and Z-axis, as well as a certain amount of displacement along the X-axis and Z-axis. The present invention is particularly suitable for applications where precise control of the direction of force transmission is required. The design of this one-way joint, through its unique structure based on three pins, enables it to be easily assembled and disassembled while maintaining high reliability and structural stability, and has good installation processability.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings.

[0028] The present invention proposes a one-way joint solution based on three pins that is easy to assemble and disassemble, and is used to transmit a one-way force without introducing forces or moments in other directions. The solution also has low positioning accuracy requirements and is easy to install, adjust and separate.

[0029] The structure of the one-way connector that can be quickly assembled and disassembled is as follows Figure 1-8 As shown, it mainly includes a U-shaped connector 12, a fork-shaped connector 5, an adjustment plate, an outer pin shaft 3, an inner pin shaft 10 and a middle pin shaft 4.

[0030] The U-shaped connector 12 comprises a U-shaped plate and a first connecting end. The U-shaped plate is fixed to the first connecting end and is U-shaped. The U-shaped plate is provided with a pair of pin holes. The internal pin 10 passes through and is fixedly connected to the pair of pin holes on the U-shaped connector 12. In this embodiment, the first connecting end and the output end of the force output device, the force actuator, are fastened to the bottom of the first connecting end of the U-shaped connector 12 via a threaded connection.

[0031] The fork connector 5 includes a fork plate and a second connection end, and the middle pin 4 passes through and is fixedly connected to a pair of pin holes on the fork plate of the fork connector 5, thereby forming a closed space. In this embodiment, the second connection end is connected to the optical mirror.

[0032] Among them, the adjustment plate includes a first adjustment plate 2 and a second adjustment plate 9. The two adjustment plates are exactly the same and are respectively installed on the two support plates of the U-shaped plate. The external pin shaft 3 passes through the closed space between the fork-shaped connector 5 and the intermediate pin shaft 4, and the two ends of the external pin shaft 3 are symmetrically fixed to the pin holes at one end of the first adjustment plate 2 and the second adjustment plate 9, respectively. The first adjustment plate 2 and the second adjustment plate 9 are fixed to a pair of screw holes on the U-shaped connector 12 through the through hole at the other end using the first adjustment screw 1 and the second adjustment screw 11.

[0033] The intermediate pin 4 and the inner pin 10 are perpendicular to each other, and the outer pin 3 is parallel to the inner pin 10, that is, the outer pin 3 and the inner pin 10 are placed in parallel, and a third pin, the intermediate pin 4, is arranged perpendicularly between them. In this way, the third pin, the intermediate pin 4, is arranged perpendicularly between the parallel outer pin 3 and the inner pin 10, and the position of the adjustment plate can be adjusted by adjusting the screw, driving the outer pin 3 to make slight position adjustments, thereby controlling the parallelism between the outer pin 3 and the inner pin 10, achieving a near-zero gap between them and the intermediate pin 4, and enabling the intermediate pin 4 and the fork-shaped connector 5, as a whole, to freely achieve a certain range of movement in the other five degrees of freedom except axial movement.

[0034] See also Figure 3 For example, when the present invention is connected to the output of a force actuator, the three-pin clamping principle ensures that the output end—the forked connector 5—only constrains translation in the Y direction. The force output by the force actuator is unrestricted in other directions, meaning that no forces or torques in other directions are generated on the connected and driven object. The structure of the outer pin 3, inner pin 10, and middle pin 4 allows the upper forked connector 5 to rotate a certain amount about the X, Y, and Z axes, as well as to move a certain amount along the X and Z axes. This invention enables the unidirectional output force of the force actuator to be transmitted in a desired direction.

[0035] The working state of the one-way connector that can be quickly assembled and disassembled according to the present invention is as follows: Figure 9-10 As shown. As a quick connection solution, the present invention fixes a quick connection seat 6 on the non-working surface of the object to be connected or driven (such as an optical mirror 7), and is provided with 4 screw holes around it, which can be screwed with fastening screws 8. The number of fastening screws 8 used can be determined according to the installation process, but should not be less than 2. The outer circular surface of the end of the fork-shaped connector 5 of the one-way joint is provided with a circle of V-shaped grooves. When connecting, it is only necessary to insert the fork-shaped connector 5 into the quick connection seat 6 and screw in the fastening screws 8 so that the end conical surface of the fastening screw 8 fits and fastens with the V-shaped groove at the end of the fork-shaped connector 5; when disassembling, it is only necessary to loosen the fastening screws 8 and pull out the fork-shaped connector 5. It should be pointed out that since the fork-shaped connector 5 has a full circle of V-shaped grooves, there is no orientation requirement when it is docked with the quick connection seat 6, so it has good installation processability and adaptability.

[0036] In summary, the present invention provides a quickly assembled and disassembled one-way joint for directing and connecting the unidirectional force output by a force actuator, while maintaining an unconstrained state in the other five degrees of freedom, thereby avoiding interfering forces and moments. Furthermore, the quick-connect joint facilitates assembly and disassembly, making it particularly suitable for applications requiring precise control of the direction of force transmission. This one-way joint, through its unique three-pin structure, maintains high reliability and structural stability while being easy to assemble and disassemble, resulting in excellent installation processability.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
