Description

Technical Field

This device has six degrees of freedom and can achieve high-precision spatial positioning and posture adjustment. It is widely used in the assembly of optical waveguides and other precision assembly processes. However, the six-axis platform has problems such as long delivery time, high price, and easy damage. Especially during the debugging and operation of the equipment, the six-axis platform is easily damaged by external force. Due to the long maintenance cycle and high cost of the six-axis platform, effective measures need to be taken to prevent it from being damaged by impact during actual use to ensure the normal operation of the equipment and extend its service life.

[0044] like Figures 1 to 7 As shown, according to an embodiment of the present invention, a platform assembly 100 is proposed. The platform assembly 100 is included in the six-degree-of-freedom platform 200 as one of the components of the six-degree-of-freedom platform 200. The platform assembly 100 includes a first fixing plate 10, a second fixing plate 20 and a magnetic part 30. The first fixing plate 10 and the second fixing plate 20 are arranged in parallel. Along a first direction (the first direction is the direction from the first fixing plate 10 to the second fixing plate 20), the first fixing plate 10 and the second fixing plate 20 are connected in a slidable manner. The first fixing plate 10 is used to connect the clamping assembly 201 of the six-degree-of-freedom platform 200, and the second fixing plate 20 is used to connect The driving component 202 of the six-degree-of-freedom platform 200, the first fixed plate 10 is provided with a first receiving groove 11 on the side away from the second fixed plate 20, the second fixed plate 20 is provided with a second receiving groove 21 on the side away from the first fixed plate 10, the first receiving groove 11 and the second receiving groove 21 are arranged opposite to each other, the magnetic part 30 includes a first magnet 31 and a second magnet 32 ​​that are magnetically attracted to each other, the first magnet 31 is detachably arranged in the first receiving groove 11, the second magnet 32 ​​is detachably arranged in the second receiving groove 21, the first magnet 31 and the second magnet 32 ​​cooperate magnetically to keep the relative displacement of the first fixed plate 10 and the second fixed plate 20 unchanged.

[0045] According to the platform assembly 100 of the present embodiment, the platform assembly 100 has a first fixed plate 10 and a second fixed plate 20, and the first fixed plate 10 and the second fixed plate 20 are connected in a slidable manner. By setting a magnetic part 30 between the first fixed plate 10 and the second fixed plate 20, the first magnet 31 and the second magnet 32 ​​that are attracted by magnetic force are used to ensure that the relative displacement between the first fixed plate 10 and the second fixed plate 20 does not change during normal operation through the magnetic attraction. However, when the first fixed plate 10 is impacted, the impact force is greater than the magnetic attraction. The magnetic adsorption connection method causes a relative displacement between the first fixed plate 10 and the second fixed plate 20, absorbs and buffers part of the impact force, thereby avoiding the impact force from being directly transmitted to the second fixed plate 20, and further avoiding the drive assembly 202 (the drive assembly 202 is a precision component in the six-degree-of-freedom platform 200) connected to the second fixed plate 20 from being subjected to the impact force, thereby reducing the risk of damage to the precision component.

[0046] Specifically, Figure 1 As shown, the first fixing plate 10 is provided with a first top screw hole 12 connected to the first receiving groove 11, and the second fixing plate 20 is provided with a second top screw hole 23 connected to the second receiving groove 21. Bolts can be screwed into the first top screw hole 12 or the second top screw hole 23 to fasten the first magnet 31 or the second magnet 32. By opening top screw holes on the first fixing plate 10 and the second fixing plate 20, and fixing the first magnet 31 and the second magnet 32 ​​with bolts, the magnets can be effectively prevented from falling off during use. In addition, users can easily inspect, maintain and replace the magnets, reduce maintenance time and cost, and ensure that the equipment is always in the best working condition.

[0047] In some embodiments, Figure 1 , Figures 4 to 6As shown, the platform assembly 100 further includes a limiting portion, and a third receiving groove 22 is further provided on the side wall of the second fixing plate 20 in a direction perpendicular to the first direction. The limiting portion includes a limiting plate and a reset member, and the limiting plate is connected to the side wall of the first fixing plate 10 in a detachable manner, and the limiting plate abuts against the side wall of the second fixing plate 20, and part of the reset member is provided in the third receiving groove 22, and the reset member is used to drive the limiting plate to abut against the second fixing plate 20. Under normal circumstances, the third magnet 71 and the fourth magnet 72 provide continuous attraction, so that the limiting plate and the second fixing plate 20 are closely attached, and the limiting plate continuously applies pressure to the second fixing plate 20, so as to ensure that there is no relative displacement between the first fixing plate 10 and the second fixing plate 20. Even when impacted by external force, the limit plate can effectively absorb part of the impact force and maintain the stability of the platform assembly 100. At the same time, when the first fixed plate 10 is impacted, the first fixed plate 10 drives the limit plate to separate from the second fixed plate 20, but under the action of the reset member, the limit plate is subjected to the restoring force of the reset member, driving the first fixed plate 10 back to its original position. In high-precision equipment, it is very important to prevent the platform assembly 100 from being impacted and thus damaging the high-precision equipment connected to it. Through the design of the limit part, the platform assembly 100 can be quickly separated and automatically reset under the action of external force, reducing equipment damage caused by impact and improving the durability of the overall system.

[0048] Specifically, Figure 6 and Figure 7 As shown, the reset member includes a third magnet 71 and a fourth magnet 72, the third magnet 71 is arranged in the third receiving groove 22, and the fourth magnet 72 is connected to the limit plate and arranged opposite to the third magnet 71. Through the magnetic force of the third magnet 71 and the fourth magnet 72, the limit plate allows the first fixed plate 10 and the limit plate to separate quickly when the platform assembly 100 is hit by an external force, thereby absorbing and buffering part of the impact force and preventing the high-precision equipment from being directly impacted and damaged. By adopting the design of magnetic adsorption connection and magnetic reset member, the platform assembly 100 can not only effectively prevent relative displacement, but also has good disassembly, safe separation and automatic reset functions. In this way, it ensures stability and reliability in daily use, and can also quickly separate and automatically recover when it is accidentally impacted, protecting the equipment from damage. The reset member provides continuous elastic force through magnetic force, further enhancing the stability and impact resistance of the system, making the platform assembly 100 more suitable for various complex working environments and requirements.

[0049] Specifically, the reset member can be a spring, and the length of the spring in the original state is less than the groove depth of the third receiving groove 22. One end of the spring is connected to the bottom of the third receiving groove 22, and the other end is connected to the limit plate. The length of the spring in the original state is less than the groove depth of the third receiving groove 22, so that the spring is always in a stretched state, ensuring that the limit plate is tightly attached to the second fixed plate 20, and limiting the first fixed plate 10 and the second fixed plate 20. At the same time, when the first fixed plate 10 is hit and drives the limit plate to separate from the second fixed plate 20, the spring's rebound force will quickly bring the limit plate back to its original position, ensuring that the platform assembly 100 is restored to its initial state.

[0050] Specifically, Figure 5 As shown, a through hole is provided on the limit plate, a groove is provided on the second fixed plate 20, the through hole is connected to the groove, one end of the guide rod is provided in the groove, and the guide rod passes through the through hole. One end of the guide rod is provided in the groove of the second fixed plate 20 and passes through the through hole of the limit plate, ensuring that the limit plate moves along the guide rod during movement. By arranging a guide rod between the limit plate and the second fixed plate 20, the guide rod passes through the through hole on the limit plate and is fixed in the groove of the second fixed plate 20, ensuring that the limit plate moves along the direction of the guide rod during movement, avoiding lateral displacement and swinging.

[0051] Specifically, the first fixed plate 10 is connected to the limiting plate by bonding. The first fixed plate 10 can be detached from the limiting plate, and can also support the limiting plate when the limiting plate is detached from the second fixed plate 20. The first fixed plate 10 and the limiting plate can be connected by a high-strength, reusable adhesive material (such as industrial-grade Velcro or strong detachable glue). The adhesive material is coated on the contact surface of the first fixed plate 10 and the limiting plate so that the two can be firmly connected and can be easily separated when needed. When the first fixed plate 10 is hit, the limiting plate can be detached from the second fixed plate 20. At this time, the first fixed plate 10 still supports the limiting plate through the adhesive material to prevent it from falling off completely. After the external force disappears, the reset member makes the limiting plate fit the second fixed plate 20 again to ensure that the limiting plate returns to its initial position.

[0052] In some embodiments, Figure 2As shown, the first fixed plate 10 and the second fixed plate 20 are square plates, and the number of the limiting plates is multiple, and each outer peripheral wall of each first fixed plate 10 is respectively provided with a limiting plate. Specifically, the number of limiting plates is four, and the four limiting plates are respectively arranged on the four side walls of the first fixed plate 10, and abut against the side walls of the second fixed plate 20, thereby forming a multi-point support structure. In this way, the external force can be evenly dispersed and the overall stability of the platform assembly 100 can be enhanced. The design of multi-point support ensures that the platform assembly 100 can maintain balance and stability under the action of external force, prevent deformation and damage caused by excessive force on a single point, and improve the durability and reliability of the system. In addition, the four limiting plates are respectively abutted against the four side walls of the second fixed plate 20 to form a stable limiting structure to prevent relative displacement between the first fixed plate 10 and the second fixed plate 20. In addition, the multi-point limiting and supporting structure can evenly disperse the external force to each limiting plate, reduce local stress concentration, and improve the impact resistance and durability of the platform assembly 100.

[0053] Specifically, the limiting plate is divided into a first limiting plate 40 and a second limiting plate 41, and the number of the first limiting plate 40 and the second limiting plate 41 is two. Assuming that the first fixed plate 10 and the second fixed plate 20 are both square plates, the two first limiting plates 40 are symmetrically arranged on the opposite sides of the first fixed plate 10 and the second fixed plate 20, and the two second limiting plates 41 are symmetrically arranged on the opposite sides of the first fixed plate 10 and the second fixed plate 20. The first limiting plate 40 is arranged along the direction in which the first fixed plate 10 and the second fixed plate 20 are prone to relative sliding displacement, and a through hole is provided on the first limiting plate 40, and a guide rod is provided in the through hole, and the guide rod is connected to the groove of the second fixed plate 20. The first limiting plate 40 is arranged in the direction in which the first fixed plate 10 and the second fixed plate 20 are prone to relative sliding displacement, and a through hole is provided on the first limiting plate 40, and a guide rod is provided in the through hole, and the guide rod is connected to the groove of the second fixed plate 20. The guide rod provides a linear guide to ensure that the relative displacement of the first fixed plate 10 and the second fixed plate 20 along the sliding direction is effectively limited.

[0054] It is understandable that in other embodiments, the first fixed plate 10 and the second fixed plate 20 are both circular plate bodies, the number of the limiting plates is two, the limiting plates are arc-shaped, and the radius of the arc of the limiting plates is the same as the radius of the circle of the first fixed plate 10, the angle of the arc is 60°, and they are respectively symmetrically arranged along the radial direction of the first fixed plate 10. The arc-shaped limiting plates can evenly disperse the external force to each contact point, reduce local stress concentration, and improve the impact resistance and durability of the platform assembly 100. The two arc-shaped limiting plates with an angle of 60° are symmetrically distributed on the circumference, which can ensure that the platform assembly 100 is evenly stressed when subjected to external force. The 60° angle design can distribute the external force over a larger contact area, which helps to reduce local stress concentration and protect the platform assembly 100 from damage.

[0055] It is understandable that if Figure 2 As shown, the circumferential edge of the first fixing plate 10 and the circumferential edge of the second fixing plate 20 are arranged flush. The circumferential edge of the first fixing plate 10 and the circumferential edge of the second fixing plate 20 are completely flush, and the flush edge design enables the two fixing plates to achieve the maximum possible docking area on the contact surface, providing greater structural stability and bearing capacity. It is also convenient for the limiting plate to limit the first fixing plate 10 and the second fixing plate 20, and the relative displacement of the limiting plate in any direction can be effectively limited, especially in a high load or high vibration environment.

[0056] It is understandable that if Figure 2 As shown, the number of the first receiving slots 11 and the number of the second receiving slots 21 are both multiple, the number of the first receiving slots 11 and the second receiving slots 21 are the same and are arranged one by one, each first receiving slot 11 is provided with a first magnet 31, and each second receiving slot 21 is provided with a second magnet 32. By providing multiple first receiving slots 11 and second receiving slots 21, each slot is provided with a first magnet 31 and a second magnet 32, respectively, the contact area and adsorption force of magnetic adsorption are increased, ensuring a firm connection between the first fixing plate 10 and the second fixing plate 20. Multi-point magnetic adsorption effectively enhances the stability and impact resistance of the platform assembly 100, prevents loosening and displacement caused by external forces during use, and improves the reliability and durability of the overall system.

[0057] Specifically, along the circumferential direction of the first fixed plate 10, a plurality of first accommodating grooves 11 are arranged at intervals on the edge of the first fixed plate 10, and a plurality of second accommodating grooves 21 are arranged one by one with the plurality of first accommodating grooves 11. The magnetic part 30 at the circumferential edge position can provide greater torque and stability, because the magnet farther from the center of the fixed plate can more effectively resist rotation and torsional stress. The magnetic part 30 arranged at the edge can enhance the anti-torque capacity of the platform assembly 100, reduce the rotation between the plates caused by external forces, and ensure the stable connection between the fixed plates. In addition, the magnetic part 30 arranged at the edge can evenly disperse the external force, avoid stress concentration in the middle position, improve the durability and impact resistance of the entire fixed plate, and extend the life of the equipment. In addition, the edge position provides a larger contact area and leverage, which increases the adsorption force and adsorption stability of the magnetic part 30. The magnetic part 30 arranged at the edge can more effectively utilize the magnetic force, provide a greater adsorption force, ensure the firm connection between the first fixed plate 10 and the second fixed plate 20, and reduce the possibility of separation.

[0058] like Figures 8 to 9 As shown, the embodiment of the utility model further provides a six-degree-of-freedom platform 200, comprising:

[0059] The platform assembly 100 described above;

[0060] A clamping assembly 201, wherein the clamping assembly 201 is connected to the first fixing plate 10, and the clamping assembly 201 is used to clamp a workpiece to be moved;

[0062] A moving assembly 203, wherein the moving assembly 203 comprises a slide rail and a moving platform slidably connected to the slide rail, and the other end of the actuating mechanism 2021 is connected to the moving platform;

The second fixing plate 20 is provided with a second mounting plate 60 , and the second mounting plate 60 is connected to the driving assembly 202 .

[0065] It is understandable that one end of each actuating mechanism 2021 is movably connected to the second fixed plate 20, and the other end is connected to the mobile platform. The actuating mechanism 2021 can be in the form of an electric cylinder, a hydraulic cylinder or a pneumatic cylinder, and six degrees of freedom motion control is achieved by independently controlling six actuating mechanisms 2021. This independent actuating design allows precise control of the movement and posture of the platform to meet complex motion requirements.

[0066] Specifically, the movable manner may be hinged.

[0067] It is understood that the moving assembly 203 includes a slide rail, which provides a linear guide and allows the moving platform to slide smoothly thereon. The moving platform is connected to the slide rail through a sliding element such as a slider or a ball bearing to ensure that the moving platform can move smoothly along the slide rail. The design of the slide rail can adopt a linear slide rail or a guide rail, and the appropriate form can be selected according to the application requirements.

[0068] In this embodiment, the six-degree-of-freedom platform 200 can unload the force when the platform is hit by external force, thereby preventing the precision parts from being damaged.

[0073] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
