Heavy objects generate significant inertial forces during starting, stopping, accelerating, or decelerating, which act directly on the floor rails. Without a cushioning mechanism, these forces can be subjected to significant impact. This long-term impact can cause fatigue cracks in the floor rails' structural components, shortening their service life. Summary of the Invention

[0024] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.
[0025] Reference Figure 1-7 The utility model provides a robot seventh axis ground rail: comprising a shell 1, a first support plate 2 is fixedly connected to the inside of the shell 1, a second support plate 3 is movably installed inside the shell 1, the second support plate 3 is located on the top of the first support plate 2, a buffer assembly 4 is installed between the first support plate 2 and the second support plate 3, a robot mounting plate 5 is slidably installed on the top of the second support plate 3, a driving assembly 6 is installed between the second support plate 3 and the robot mounting plate 5, and a lubrication assembly 7 is installed inside the shell 1; the buffer assembly 4 includes a first ear plate 401, a connecting block 402, a first mounting block 403, and a movable block 40 4. Slide groove 405 and first spring 406. The first ear plate 401 has four rectangular fixed connections to the top of the first support plate 2. The connecting block 402 is movably installed inside the two first ear plates 401. The first mounting block 403 has two fixed connections to the bottom of the second support plate 3. The movable block 404 is movably installed on the end of the connecting block 402 away from the first ear plate 401. The slide groove 405 is opened inside the first mounting block 403. The movable block 404 is located inside the slide groove 405. The first spring 406 is fixed with multiple fixed installations inside the first mounting block 403 and fixedly connected to the movable block 404.
[0026] During use, the robot is installed on the robot mounting plate 5, and then the robot mounting plate 5 is driven to move by the driving assembly 6. When the robot carries heavy objects, if a downward impact force is generated, the second support plate 3 moves downward relative to the first support plate 2. At the same time, through the cooperation of the connecting block 402, the movable block 404 moves in the slide groove 405, and at the same time, multiple first springs 406 are squeezed to convert the impact energy into elastic potential energy, thereby playing a buffering role. During the movement of the robot mounting plate 5, the lubrication assembly 7 is turned on to lubricate the driving assembly 6 and the robot mounting plate 5.
[0027] like Figure 3 As shown, the buffer assembly 4 further includes a damper 407 . The damper 407 has four rectangular parts fixedly connected to the bottom of the second support plate 3 , and the bottom of the damper 407 is fixedly mounted on the top of the first support plate 2 .
[0028] When the robot carries a heavy object and generates an impact force, the second support plate 3 moves downward and the damper 407 is compressed. Through the principle of the damper 407 itself, the impact force is absorbed and dispersed, thereby enhancing the buffering effect. The model of the damper 407 is G22-40.
[0029] like Figure 5 As shown, the drive assembly 6 includes a second ear plate 601, a screw rod 602, a slide rod 603, a drive motor 604 and a third ear plate 605. The second ear plate 601 has four fixed connections to the top of the second support plate 3, the screw rod 602 is movably installed between the two second ear plates 601, the slide rod 603 is fixedly installed between the two second ear plates 601, the drive motor 604 is fixedly installed inside the shell 1, the screw rod 602 is fixedly installed at the output end of the drive motor 604, and the third ear plate 605 is fixedly connected to the bottom of the robot mounting plate 5. A screw hole corresponding to the screw rod 602 is opened inside the third ear plate 605 close to the side of the screw rod 602, and a sliding hole corresponding to the slide rod 603 is opened inside the third ear plate 605 close to the side of the slide rod 603.
[0030] During use, the drive motor 604 is turned on and the screw rod 602 rotates. Due to the threaded fit between the screw rod 602 and the third ear plate 605 and the guiding effect of the slide rod 603 on the third ear plate 605, the robot mounting plate 5 will move along the axial direction of the screw rod 602.
[0031] like Figure 7 As shown, the drive assembly 6 also includes a second mounting block 606 and a roller 607. The second mounting block 606 has two fixed connections to the bottom of the robot mounting plate 5. The second mounting block 606 is located between the two third ear plates 605. The roller 607 has multiple movable mountings inside the second mounting block 606, and the roller 607 is in contact with the top of the second support plate 3.
[0032] When the robot mounting plate 5 moves, the roller 607 contacts the second support plate 3 . The rolling characteristics of the roller 607 can reduce the friction between the robot mounting plate 5 and the second support plate 3 , making the robot move more smoothly.
[0033] like Figure 6-7 As shown, the lubrication assembly 7 includes an oil pump 701, a rubber oil pipe 702 and an oil tank 703. The oil pump 701 is fixedly mounted on the bottom of the inner wall of the outer shell 1. The rubber oil pipe 702 is fixedly mounted on the oil outlet end of the oil pump 701 and passes through the first support plate 2 and the second support plate 3 and is connected to the bottom of the robot mounting plate 5. The oil tank 703 is opened inside the robot mounting plate 5 and is connected to the rubber oil pipe 702. The oil tank 703 is communicated with the interior of the second mounting block 606 and the third ear plate 605. Lubricating oil is stored inside the outer shell 1, and the lubricating oil is located at the bottom of the first support plate 2.
[0034] When in use, the oil pump 701 is turned on to transport the lubricating oil stored in the housing 1 to the oil tank 703 through the rubber oil pipe 702. The lubricating oil then diffuses from the oil tank 703 to the second mounting block 606 and the third ear plate 605 to form a lubricating oil film. The lubricating oil film reduces the friction between the components and reduces wear.
[0035] like Figure 2-3 As shown, a plurality of first oil leakage holes 201 are opened inside the first support plate 2 , and a plurality of second oil leakage holes 301 are opened inside the second support plate 3 .
[0036] During the lubrication process, excess lubricating oil can flow back to the bottom of the housing 1 through the first oil leakage hole 201 and the second oil leakage hole 301, thereby realizing the recycling of the lubricating oil and avoiding excessive accumulation of lubricating oil on the support plate, which affects the normal operation of the system.
[0037] Working principle: First, when in use, the robot is installed on the robot mounting plate 5.
[0038] Then, the drive motor 604 is turned on and the screw rod 602 rotates. Due to the threaded fit between the screw rod 602 and the third ear plate 605, and the guiding effect of the slide rod 603 on the third ear plate 605, the robot mounting plate 5 will move along the axial direction of the screw rod 602. During the movement, the roller 607 contacts the second support plate 3. The rolling characteristics of the roller 607 can reduce the friction between the robot mounting plate 5 and the second support plate 3, making the robot movement smoother.
[0039] When the robot mounting plate 5 moves, the oil pump 701 is turned on to transport the lubricating oil stored in the shell 1 to the oil tank 703 through the rubber oil tube 702. The lubricating oil then diffuses from the oil tank 703 to the second mounting block 606 and the third ear plate 605 to form a lubricating oil film. The lubricating oil film reduces the friction between the components and reduces wear. Then, the excess lubricating oil can flow back to the bottom of the shell 1 through the first oil leakage hole 201 and the second oil leakage hole 301, realizing the recycling of the lubricating oil and avoiding excessive accumulation of lubricating oil on the support plate, which affects the normal operation of the system.
[0040] When the robot carries heavy objects, if a downward impact force is generated, the second support plate 3 moves downward relative to the first support plate 2. At the same time, through the cooperation of the connecting block 402, the movable block 404 moves in the slide groove 405, and at the same time, multiple first springs 406 are squeezed to convert the impact energy into elastic potential energy, thereby playing a buffering role. At the same time, the second support plate 3 moves downward, and the damper 407 is compressed accordingly. Through the principle of the damper 407 itself, the impact force is absorbed and dispersed, thereby enhancing the buffering effect.
[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
