[0004] However, the existing track structure is relatively simple, mainly consisting of guide rails and a sliding platform. The robot is mainly fixed on the surface of the platform. During the movement of the guide rails, the platform is prone to sliding displacement, which affects the installation stability of the robot.

[0005] Therefore, it is necessary to redesign and modify the mobile tracks of industrial robots. Utility Model Content

[0016] 2. This utility model achieves automated control of clamping force through the cooperation of transmission motor and threaded assembly, replacing manual operation.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1 to 4 As shown, the present invention provides a mobile track for an industrial robot, including a guide rail 1;

[0028] A platform 2 is slidably connected to the surface of the guide rail 1. A bracket 3 is fixedly connected to both ends of the guide rail 1. A shaft 4 is inserted into the inner side of the bracket 3. A cleaver 5 located on both sides of the guide rail 1 is fixedly connected to the surface of the shaft 4. The side of the cleaver 5 away from the shaft 4 contacts the surface of the platform 2. A transmission structure is provided on both sides of the guide rail 1. The transmission structure can control the clamping of the cleaver 5.

[0029] refer to Figure 2The transmission structure includes a connecting frame 6 fixedly connected to both sides of the guide rail 1. A transmission motor 7 is fixedly connected to the top of the connecting frame 6. A threaded assembly 8 is fixedly connected to the output end of the transmission motor 7. The end of the threaded assembly 8 away from the transmission motor 7 passes through the connecting frame 6 and is movably connected to the connecting frame 6. A lifting plate 9 is threadedly connected to the surface of the threaded assembly 8. Both ends of the shaft 4 are fixedly connected to a sleeve plate 10. The side of the sleeve plate 10 away from the shaft 4 extends to the inside of the lifting plate 9. A push rod 11 located inside the sleeve plate 10 is fixedly connected to the inside of the lifting plate 9. The push rod 11 and the sleeve plate 10 are slidably connected.

[0030] As a technical optimization of this utility model, the automatic control of clamping force is realized through the cooperation of the transmission motor 7 and the threaded assembly 8, replacing manual operation. The lifting plate 9 pushes the sleeve plate 10 through the push rod 11, which converts the rotational motion of the threaded assembly 8 into the linear displacement of the shaft 4, making the clamping action of the chuck 5 more precise.

[0031] refer to Figure 3 The connecting frame 6 is fixedly connected to the guide bar 12, and the lifting plate 9 is sleeved on the surface of the guide bar 12 and slidably connected to the guide bar 12.

[0032] As a technical optimization of this utility model, the movement trajectory of the lifting plate 9 is constrained by the guide bar 12 to ensure that its vertical lifting is without deviation, avoid uneven clamping force of the claw 5 or mechanism jamming caused by the tilt of the lifting plate 9, and improve the reliability of the system.

[0033] refer to Figure 3 The top of the guide rail 1 is provided with an extrusion plate 13 located at the bottom of the platform 2. The two ends of the extrusion plate 13 extend into the interior of the two connecting frames 6 and are fitted onto the surface of the threaded assembly 8. The threaded assembly 8 is threadedly connected to the extrusion plate 13.

[0034] As a technical optimization of this utility model, by adding a squeezing plate 13, the platform 2 is lifted from the bottom upwards, forming a bidirectional constraint with the downward clamping force of the claw 5.

[0035] refer to Figure 3 The threaded assembly 8 includes two screws 14, the inner ends of which are connected to each other by a coupling 15. The threads of the two screws 14 are in opposite directions. The lifting plate 9 is sleeved on the surface of the bottom screw 14 and threadedly connected to the bottom screw 14. The pressing plate 13 is sleeved on the surface of the top screw 14 and threadedly connected to it.

[0036] As a technical optimization of this utility model, the double screw 14 reverse thread design is driven by a single motor to synchronously control the lifting plate 9 and the pressing plate 13, thereby achieving a coordinated action of bidirectional locking.

[0037] refer to Figure 3The guide strip 12 is located on both sides of the extrusion plate 13, and the guide strip 12 and the extrusion plate 13 are slidably connected.

[0038] As a technical optimization of this utility model, the guide bar 12 extends to both sides of the extrusion plate 13 to provide it with the same vertical movement guidance as the lifting plate 9, ensuring that the extrusion plate 13 is lifted without deviation.

[0039] The working principle and usage process of this utility model: When the mobile track of the industrial robot is working, the platform 2 can slide freely along the surface of the guide rail 1. When locking is required, the transmission motor 7 in the transmission structure on both sides of the guide rail 1 is activated, driving the threaded assembly 8 composed of two screws 14 with opposite screw directions to rotate synchronously. The rotational motion produces two actions at the same time. The bottom screw 14 drives the lifting plate 9 to slide vertically downward along the guide bar 12 in the connecting frame 6, while the top screw 14 drives the pressing plate 13 located at the top of the guide rail 1 to slide vertically upward along the guide bar 12. When the lifting plate 9 moves down, it pushes the sleeve plate 10 fixed at both ends of the shaft 4 to move down through the push rod 11 on its inner side, causing the shaft 4 and the claws 5 on both sides to rotate downward. The downward clamping force of the claw 5 is applied to the surface of the platform 2 by the end of the claw 5. At the same time, the pressing plate 13 moves upward and contacts the bottom of the platform 2, providing upward support. The downward clamping force of the claw 5 and the upward lifting force of the pressing plate 13 work together to form a three-point three-dimensional constraint on the platform 2, which stably locks it on the guide rail 1 and effectively prevents sliding displacement. When unlocking, the drive motor 7 reverses, the lifting plate 9 drives the claw 5 to move upward to release the platform 2, and the pressing plate 13 moves downward to reset. The platform 2 can then return to a free sliding state. The guide bar 12 ensures the linearity and stability of the movement of the lifting plate 9 and the pressing plate 13. The whole process realizes the automated and rapid locking and releasing of the platform 2, which significantly improves the installation stability of the robot.

[0040] In summary, the mobile track of this industrial robot, by setting up a linkage structure between the shaft 4 and the gripper 5, uses a transmission structure to control the gripper 5 to apply active clamping force to the surface of the platform 2, which fundamentally solves the problem of easy slippage and displacement of the platform 2 in traditional tracks. The locking method of direct contact between the gripper 5 and the platform 2 significantly improves the stability of robot installation, and no additional complex braking device is required.
