[0026] The present invention will be further described in detail below with reference to embodiments:

[0027] like Figures 1-5 As shown, this utility model has the following three specific embodiments.

[0028] Example 1

[0029] This utility model provides a mobile base for an industrial robot, including a mobile frame body 1, a slide rail 2 fixedly installed on the outside of the mobile frame body 1, a mobile slide plate 3 movably installed on the outside of the slide rail 2, a reinforcing base 4 fixedly installed on the top of the mobile slide plate 3, and a connecting base 5 fixedly installed on the top of the reinforcing base 4.

[0030] Also includes:

[0031] A connecting mechanism is located at the top of the inner cavity of the connecting base 5, which is used for convenient assembly of industrial robot connecting components;

[0032] The shock absorption mechanism is located at the bottom of the inner cavity of the connecting base 5. It is installed with shock absorption components to buffer and mitigate the vibration generated during the movement of the base, thereby reducing the impact on the industrial robot.

[0033] like Figure 1 As shown, when the working position of the industrial robot needs to be adjusted, the movable slide plate 3 can slide smoothly along the slide rail 2, driving the top reinforced base 4 and the connecting base 5 to move synchronously, thereby flexibly changing the spatial position of the robot to meet the position requirements of different working scenarios. The connecting mechanism, as the key to achieving rapid assembly of the industrial robot, is located at the top of the inner cavity of the connecting base 5, achieving precise docking with the connecting components of the industrial robot for convenient installation. In addition, the shock absorption mechanism is installed at the bottom of the inner cavity of the connecting base 5, its main function being to mitigate the impact of vibrations generated during the movement of the device on the industrial robot. When the movable slide plate 3 moves along the slide rail 2, or when the device is subjected to external impact, the vibration will be transmitted to the connecting base 5 through components such as the movable frame body 1, the slide rail 2, and the movable slide plate 3. At this time, the buffer components in the shock absorption mechanism will absorb and dissipate the vibration energy through their own deformation or damping effect, minimizing the vibration amplitude transmitted to the industrial robot and increasing the stability of the base.

[0034] Example 2

[0035] The difference from Embodiment 1 is that this embodiment discloses an assembly shaft 56, a connecting shaft 55, a fixed base shaft 51, and a shock-absorbing base 53. The connecting mechanism includes the assembly shaft 56 and the connecting shaft 55. A snap-fit ​​seat 551 is fixedly installed inside the connecting shaft 55. A connecting hole 552 is opened on the top of the snap-fit ​​seat 551. A connecting post 561 is movably sleeved inside the connecting hole 552. The top of the connecting post 561 is fixedly installed on the bottom of the assembly shaft 56. A threaded shaft 553 is threadedly connected to the outside of the connecting shaft 55. The other end of the threaded shaft 553 is threadedly connected to the outside of the assembly shaft 56. The damping mechanism includes a fixed bottom shaft 51 and a damping base 53. The fixed bottom shaft 51 is fixedly installed at the bottom of the inner cavity of the connecting base 5. A support column 52 is fixedly installed inside the fixed bottom shaft 51. The top of the support column 52 is movably sleeved on the top of the damping base 53. A buffer column 531 is movably installed on the top of the damping base 53. A pressing plate 533 is fixedly sleeved on the top of the buffer column 531. A spring 532 is movably sleeved on the bottom of the buffer column 531. A damping plate 54 is fixedly installed on the top of the buffer column 531. The top of the damping plate 54 is fixedly installed on the bottom of the connecting shaft 55.

[0036] likeFigure 2 , 3 As shown in Figure 4, during the assembly of the industrial robot, the connecting post 561 at the bottom of the assembly shaft 56 is precisely inserted into the connecting hole 552 at the top of the snap-fit ​​seat 551 inside the connecting shaft 55, forming a preliminary positioning connection to ensure the accurate relative position of the assembly shaft 56 and the connecting shaft 55 in the vertical direction. Then, by rotating the threaded shaft 553 on the outside of the connecting shaft 55, its other end is threaded to the outside of the assembly shaft 56, further securing the two using the tightness of the threaded connection, achieving convenient assembly. Additionally, the fixed bottom shaft 51 is fixed to the bottom of the inner cavity of the connecting base 5, providing stable support for the entire shock absorption mechanism. The top of its internal support post 52 is movably sleeved on the bottom of the shock absorption base 53, providing vertical support and guidance for the shock absorption base 53. When the movable slide plate 3 moves along the slide rail 2 or the device vibrates due to external impact, the vibration is transmitted sequentially through the moving frame body 1, slide rail 2, movable slide plate 3, reinforced base 4, and connecting base 5 to the fixed bottom shaft 51, and then to the shock absorption base 53. At this time, the damping plate 54 will be subjected to pressure transmitted from the connecting shaft 55 above, causing the buffer column 531 to move downwards. The spring 532 at the bottom of the buffer column 531 will be compressed, and the elastic deformation of the spring will absorb some of the vibration energy. At the same time, the pressing plate 533 will move downwards with the buffer column 531, further applying pressure to the spring 532 and enhancing the buffering effect. The support column 52 can limit the lateral sway of the damping base 53, ensuring the stability of the damping process. By utilizing the buffering effect, the vibration amplitude transmitted to the connecting shaft 55 and the industrial robot above is greatly weakened, effectively reducing vibration and increasing the stability of the base.

[0037] Example 3

[0038] The difference from Embodiment 2 is that this embodiment discloses a lifting column 534, a ring plate 535, and a telescopic column 536. A fixing block 537 is fixedly installed inside the shock-absorbing base 53, and a lifting column 534 is fixedly installed inside the fixing block 537. A ring plate 535 is fixedly installed on the outer side of the top of the lifting column 534, and a telescopic column 536 is movably connected to the outer side of the ring plate 535. The bottom of the telescopic column 536 is movably connected to the top of the fixing block 537.

[0039] like Figure 5 As shown, when the damping base 53 is subjected to pressure, the lifting column 534 retracts and moves, and the ring plate 535 on its outer top moves down synchronously, thereby driving the telescopic column 536 to retract and move. By utilizing its own telescopic deformation, it further absorbs and disperses vibration energy, effectively sharing the pressure borne by the spring 532, and increasing the damping function of the damping mechanism.

[0040] The working principle of the mobile base of this industrial robot will be explained in detail below.

[0041] like Figures 1-5As shown, when the working position of the industrial robot needs to be adjusted, the movable slide plate 3 can slide smoothly along the slide rail 2, driving the top reinforced base 4 and connecting base 5 to move synchronously, thereby flexibly changing the spatial position of the robot to meet the position requirements of different working scenarios. When assembling the industrial robot, the connecting post 561 at the bottom of the assembly shaft 56 will be precisely inserted into the connecting hole 552 at the top of the snap-fit ​​seat 551 inside the connecting shaft 55, forming a preliminary positioning connection to ensure the accurate relative position of the assembly shaft 56 and the connecting shaft 55 in the vertical direction. Then, by rotating the threaded shaft 553 on the outside of the connecting shaft 55, its other end is threaded to the outside of the assembly shaft 56, and the tightness of the threaded connection is used to further lock the two together, achieving the function of convenient assembly. In addition, the fixed bottom shaft 51 is fixed to the bottom of the inner cavity of the connecting base 5, providing stable support for the entire shock absorption mechanism. The top of the support post 52 inside it is movably sleeved on the bottom of the shock absorption base 53, providing vertical support and guidance for the shock absorption base 53. When the movable slide plate 3 moves along the slide rail 2 or the device vibrates due to external impact, the vibration is transmitted sequentially through the movable frame body 1, slide rail 2, movable slide plate 3, reinforced base 4, and connecting base 5 to the fixed bottom shaft 51, and then to the shock-absorbing base 53. At this time, the shock-absorbing plate 54 is subjected to pressure transmitted from the connecting shaft 55 above, causing the buffer column 531 to move downward. The spring 532 at the bottom of the buffer column 531 is compressed, and the elastic deformation of the spring absorbs some of the vibration energy. At the same time, the pressing plate 533 moves downward with the buffer column 531, further applying pressure to the spring 532 and enhancing the cushioning effect. The support column 52 can limit the lateral sway of the shock-absorbing base 53, ensuring the stability of the shock absorption process.

[0042] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
