Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical parts, and particularly relates to a slider with multi-directional buffering. Background Technique

[0002] The linear guide rail system is a high-precision mechanical motion component, which is widely used in various fields such as industrial automation equipment, numerical control machine tools, and precision measuring instruments. It consists of a guide rail and a slider. The guide rail is usually fixed on the base or frame of the machine, while the slider is installed on the component that needs to perform linear motion. Ball bearings or rollers are installed inside the slider, and these rolling elements roll in the grooves of the guide rail, thus realizing low-friction and high-precision linear motion. The linear guide rail system has the advantages of strong load-bearing capacity, stable motion, high positioning accuracy, and simple maintenance, and is an indispensable key component in modern mechanical design.

[0003] At present, the contact surface between the slider and the guide rail may be worn due to excessive lateral force, and even cause permanent damage, thereby reducing the accuracy and service life of the system. Secondly, the lack of a buffering function means that the system cannot effectively absorb and disperse impact energy, which may lead to sudden displacement or misalignment of the moving components, affecting the stability and repeat positioning accuracy of the equipment. In high-speed or high-acceleration motion, the slider without a buffering function may generate noise and vibration, which not only affects the working environment, but also may have a negative impact on the performance and reliability of the entire mechanical system.

[0039] In this embodiment, the front buffer mechanism 9 includes a buffer block 901, an arc-shaped groove 902, a positioning ring sleeve 903, a connecting column 904, an injection hole 905, a support ring plate 906, a buffer spring 907, a movable telescopic rod 908, and a buffer anti-collision plate 909. The number of buffer blocks 901 is four, and they are evenly distributed around the inner wall of the cavity of the front buffer mechanism 9. The arc-shaped groove 902 is opened on the inner side of the buffer block 901. The positioning ring sleeve 903 is fixedly installed at the center of the cavity of the front buffer mechanism 9. The number of connecting columns 904 is four, and they are respectively fixedly installed around the outer surface of the positioning ring sleeve 903. The injection hole 905 is opened on the top of the front buffer mechanism 9. One side of the support ring plate 906 is fixedly connected to one end of the connecting column 904.

The arc-shaped grooves 902 on their inner sides are designed to increase the contact area and improve the buffer efficiency. The combination of the positioning ring sleeve 903 and the connecting column 904 ensures the stable positioning of the center of the front buffer mechanism 9. The synergistic effect of the support ring plate 906, the buffer spring 907, and the movable telescopic rod 908 enables the energy to be effectively absorbed by the buffer spring 907 and dispersed through the telescopic movement of the movable telescopic rod 908 when subjected to a frontal impact.

[0041] Embodiment 4

[0042] Referring to Figure 1 and Figure 2 , this is the fourth embodiment of the present utility model, and this embodiment is based on the first three embodiments.

The limit sleeve 17 is sleeved on the surface of the limit rod 18. A fixed block 10 is provided on the outer side of the base 1, and a fastening knob 11 is threadedly installed on the outer side of the fixed block 10.

[0044] As Figure 1 and Figure 2 shown, the inflatable airbag 13 provides additional buffering in the up and down directions for the positioning slider 12, enhancing its shock absorption effect when subjected to vertical impact. The damping shock absorber 16 can effectively absorb and disperse the energy of lateral impact. The cooperation between the limit sleeve 17 and the limit rod 18 on the base 1 ensures the precise position and movement trajectory of the positioning slider 12 on the guide rail 2. The fixed block 10 and the fastening knob 11 on the outer side of the base 1 provide additional fixing and adjustment functions, making the entire system more stable and easy to maintain.

[0045] During use, it is fixed on the supporting inclined plate 502 by placing the shell sleeve 501. The first damping spring 503 and the second damping spring 505 are accommodated inside, and are respectively connected to the first damping block 504 and the second damping block 506 to form a dual damping mechanism. The buffer backing plate 509 further enhances the buffering effect, ensuring that when subjected to a lateral impact, the energy can be absorbed and dispersed, thereby protecting the positioning slider 12 and the guide rail 2 from damage, improving the stability and durability of the positioning slider 12. The four buffer blocks 901 are evenly distributed around the inner cavity of the front buffer mechanism 9. The arc-shaped groove 902 designed on the inner side increases the contact area and improves the buffering efficiency. The combination of the positioning collar 903 and the connecting column 904 ensures the stable positioning of the center of the front buffer mechanism 9.

The setting of the buffer anti-collision plate 909 further enhances the anti-collision ability, protects the positioning slider 12 from frontal impact damage, and improves the anti-impact performance of the positioning slider 12. The inflatable airbag 13 provides additional buffering in the up and down directions for the positioning slider 12, enhancing its shock absorption effect when subjected to a vertical impact. The damping shock absorber 16 can effectively absorb and disperse the energy of the lateral impact. The limit sleeve 17 cooperates with the limit rod 18 on the base 1 to ensure the accurate position and movement trajectory of the positioning slider 12 on the guide rail 2. The fixing block 10 and the fastening knob 11 on the outside of the base 1 provide additional fixing and adjustment functions.

[0046] In summary: By integrating the side buffer mechanism 5 and the front buffer mechanism 9, the anti-impact and shock absorption capabilities of the positioning slider 12 in multiple directions are significantly improved. The side buffer mechanism 5 is located on the front of the supporting side plate 4 and can provide buffering when the positioning slider 12 is subjected to a lateral impact, protecting the supporting side plate 4 and the base 1 from damage, while ensuring the stability and movement accuracy of the positioning slider 12.
