Description
Technical Field

[0002] Ground rails are cast iron base equipment used for the assembly, testing, welding, inspection, and transportation of large equipment. They replace traditional integral platforms with modular splicing designs, which has the core advantages of saving material costs and space. They are used in many industrial fields such as machinery manufacturing and electronics production.
[0003] When the ground rail mechanism works in conjunction with a robotic arm, and the robotic arm is used to transfer large workpieces, such as moving the workpiece from the placement table to the manual welding area, and then taking the workpiece from the manual welding area and moving it to the discharge end, vibration will occur when the robotic arm moves to the welding area and rotates. The slide of the traditional ground rail mechanism is prevented from moving only by the force of the meshing of gears and racks. On the one hand, the motor is prone to damage, and on the other hand, displacement may still occur, resulting in a decrease in accuracy. Therefore, an improved technology is urgently needed to solve this problem existing in the current technology. Summary of the Invention

L-shaped baffles are symmetrically arranged on both sides of the ground rail base. Guide rails are also symmetrically arranged on both sides of the upper surface of the ground rail base. A rack is arranged on any side of the upper surface of the ground rail base. The lower surface of the slide is slidably connected to the guide rail via a guide block, and the upper surface of the slide is connected to a robotic arm via a bearing seat.

[0015] Please see Figure 1-4 This utility model provides a technical solution: a ground rail mechanism for use with a robotic arm, comprising a ground rail body, a slide table 5, a drive mechanism, a braking mechanism, and a robotic arm 7; The main body of the ground rail includes a ground rail base 1, a guide rail 2, and a rack 3. L-shaped baffles 4 are symmetrically arranged on both sides of the ground rail base 1. Guide rails 2 are also symmetrically arranged on both sides of the upper surface of the ground rail base 1. A rack 3 is arranged on any side of the upper surface of the ground rail base 1. Several fixing plates 14 are arranged on both sides of the ground rail base 1. Fixing plates 14 are connected to fixing feet 15. Fixing feet 15 are connected to fixing plates 14. The height of fixing feet 15 is adjusted by screws and nuts to adapt to the installation area. Fixing feet 15 are connected to the mounting base by expansion screws. A drag chain 16 is provided in the middle of the ground rail base 1 to facilitate the wiring of the connecting lines of the robotic arm 7, servo motor 9, and electric cylinder 12. The lower surface of the slide table 5 is slidably connected to the guide rail 2 via a guide block. The guide rail 2 is set inside the L-shaped baffle 4. The two sides of the slide table 5 are movably set inside the L-shaped baffle 4. The guide rail 2 and the two sides of the slide table 5 are blocked by the L-shaped baffle 4 to ensure safety. The upper surface of the slide table 5 is connected to the robotic arm 7 via a bearing 6. The upper surface of the slide table 5 is provided with a bracket 8. The drive mechanism includes a servo motor 9 and a drive gear 10. The servo motor 9 is mounted on the upper surface of the slide table 5 through a reduction gearbox 11. The output shaft of the reduction gearbox 11 passes through the slide plate and is equipped with the drive gear 10. The drive gear 10 meshes with the rack 3. The slide table 5 can also be equipped with an auxiliary gear through a rotating rod to improve the stability of the slide table 5. The braking mechanism includes an electric cylinder 12 and a rubber pressure block 13. The electric cylinder 12 is mounted on the bracket 8. The piston rod of the electric cylinder 12 is fitted with the rubber pressure block 13. The top of the rubber pressure block 13 is sleeved with the piston rod of the electric cylinder 12 and fastened with bolts to facilitate the installation and disassembly of the rubber pressure block 13, thereby facilitating the replacement of the rubber pressure block 13. The rubber pressure block 13 is pressed into fit with the upper surface of the L-shaped baffle 4 on the corresponding side. like Figure 4 As shown, the bracket 8 includes a support plate 801 and a horizontal plate 802. The horizontal plate 802 is connected to one side of the support plate 801 by bolts and nuts. The electric cylinder 12 is installed on the upper surface of the horizontal plate 802. The installation of the electric cylinder 12 is achieved through the horizontal plate 802.
[0016] Working method and principle: The servo motor 9 and the drive gear 10 reducer work together to drive the drive gear 10 to rotate. The drive gear 10 meshes with the rack 3. When the drive gear 10 rotates, the slide 5 moves laterally along the guide rail 2, thereby realizing the movement of the robotic arm 7. The robotic arm 7 consists of multiple links, joints, motors, transmission mechanisms (such as reducers), and internal sensors. The head of the robotic arm 7 is equipped with grippers according to actual needs. After the robotic arm grips the workpiece with the grippers, the servo motor 9 drives the slide 5 to move along the guide rail 2 to the corresponding position. Then, the piston rod of the electric cylinder 12 moves downward and presses the rubber pressure block 13 against the upper surface of the L-shaped baffle 4. At this time, the slide 5 will not be displaced due to the swing of the robotic arm 7. This utility model has a reasonable structure. An electric cylinder 12 is installed on the upper surface of the slide table 5 through the bracket 8. A rubber pressure block 13 is installed on the piston rod of the electric rod. When the slide table 5 moves to the corresponding position and the robotic arm 7 swings, the rubber pressure block 13 presses against the L-shaped baffle 4. By increasing the friction, the robotic arm 7 can prevent the slide table 5 from shifting during operation, ensuring the movement accuracy of the slide table 5 and protecting the motor. At the same time, after being pressed by the rubber pressure block 13, the slide table 5 will not shake when the robotic arm 7 swings, thus improving the overall stability.
