[0002] Robotic arms play a vital role in modern industrial production. They can mimic certain movements and functions of human hands and arms, grasping, moving objects or operating tools according to fixed programs. They are widely used in many fields such as automobile manufacturing, electronics production, and logistics transportation. Their characteristic is that they can be programmed to complete various expected tasks. In terms of structure and performance, they combine the advantages of both humans and machines. Robotic arms are the earliest industrial robots and the earliest modern robots. They can replace heavy human labor to realize the mechanization and automation of production. They can operate in harmful environments to protect personal safety. Therefore, they are widely used in machinery manufacturing, metallurgy, electronics, light industry, and nuclear energy sectors.

[0003] However, existing robotic arms are mostly fixed to the surface of the operating table with bolts during assembly and installation. When assembling and disassembling, multiple bolts need to be tightened to ensure a firm assembly, which affects the assembly efficiency. During disassembly, the robotic arm also needs to be supported to prevent the bolts from getting stuck due to tilting, which brings inconvenience to the user's assembly and disassembly work.

[0004] Therefore, it needs to be modified to allow for a convenient plug-in assembly structure that can stably and securely assemble the robotic arm onto the operating table, and facilitate disassembly when maintenance or replacement is required, thus providing convenience for the user.

It features a convenient plug-in assembly structure, enabling stable and secure assembly of the robotic arm onto the operating table. It also allows for easy disassembly when maintenance or replacement is required, providing convenience for the user. This solves the problem that existing robotic arms are mostly fixed to the operating table surface with bolts during assembly and installation. This requires tightening multiple bolts to ensure a secure assembly, affecting assembly efficiency. Furthermore, disassembly requires supporting the robotic arm to prevent bolt jamming due to tilting, causing inconvenience for the user during assembly and disassembly.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a conveniently assembled robotic arm, comprising an assembly base and a structural box. An electric slide rail assembly is provided at the bottom of the assembly base, and an operating table is fixedly connected to the bottom of the electric slide rail assembly. The bottom of the assembly base is fixedly connected to the output end of the electric slide rail assembly.

A lead screw is provided inside the structural box, with its top and bottom ends rotatably connected to the top and bottom of the inner wall of the structural box, respectively. A first bevel gear is fixedly connected above the surface of the lead screw. A circular hole is opened on the front of the structural box, and a circular rod is rotatably connected inside the circular hole. The rear of the circular rod... The end extends into the interior of the structural box and is fixedly connected to a second bevel gear. The surface of the second bevel gear meshes with the surface of the first bevel gear. A rotating wheel is fixedly connected to the front end of the round rod. A nut seat is threadedly connected to the lower surface of the lead screw. Movable slots are provided on both the left and right sides of the structural box, and positioning plates are attached to the inside of the movable slots. The upper inner sides of the two positioning plates are fixedly connected to the surface of the nut seat. Insertion slots are provided on both the left and right sides of the assembly base. A positioning pin slot is provided on the lower part of the assembly base, which runs through the insertion slots and communicates with them. The surface of the positioning plate is attached to the inner wall of the insertion slot. A through hole is provided on the lower part of the positioning plate, which communicates with the positioning pin slot. A positioning bolt is inserted into the positioning pin slot and the through hole.

[0007] As a preferred embodiment of this utility model, a support frame is fixedly connected to the surface of the support rod, and vertical rods are fixedly connected to the bottom of each of the four corners of the support frame.

[0008] As a preferred embodiment of this utility model, the bottom of the vertical rod is provided with a groove, and a ball bearing is rolled inside the groove, the surface of the ball bearing being in contact with the surface of the operating table.

[0020] 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.

[0021] like Figures 1 to 4As shown, this utility model provides a conveniently assembled robotic arm, including an assembly base 1 and a structural box 2. An electric slide rail assembly 3 is provided at the bottom of the assembly base 1, and an operating table 4 is fixedly connected to the bottom of the electric slide rail assembly 3. The bottom of the assembly base 1 is fixedly connected to the output end of the electric slide rail assembly 3. A support rod 5 is fixedly connected to the top of the structural box 2, and a robotic arm gripping part 6 is fixedly connected to the top of the support rod 5. A lead screw 7 is provided inside the structural box 2, with its top and bottom ends rotatably connected to the top and bottom of the inner wall of the structural box 2, respectively. A first bevel gear 8 is fixedly connected to the upper surface of the lead screw 7. A circular hole is opened on the front of the structural box 2, and a circular rod 9 is rotatably connected inside the circular hole. The rear end of the circular rod 9 extends into the interior of the structural box 2 and is fixedly connected to a second bevel gear 10. The surface of bevel gear 10 meshes with the surface of the first bevel gear 8. A rotating wheel 11 is fixedly connected to the front end of the round rod 9. A nut seat 12 is threadedly connected to the lower surface of the lead screw 7. The surface of the nut seat 12 is slidably connected to the inner wall of the structure box 2. Moving slots are provided on both the left and right sides of the structure box 2, and positioning plates 13 are attached to the inside of the moving slots. The upper inner sides of the two positioning plates 13 are fixedly connected to the surface of the nut seat 12. Insertion slots 14 are provided on both the left and right sides of the assembly base 1. A positioning pin slot 15 is provided on the lower part of the assembly base 1, which is connected to the insertion slot 14. The surface of the positioning plate 13 is attached to the inner wall of the insertion slot 14. A through hole 16 is provided on the lower part of the positioning plate 13, which is connected to the positioning pin slot 15. A positioning bolt 17 is inserted into the positioning pin slot 15 and the through hole 16.

[0022] refer to Figure 1 A support frame 18 is fixedly connected to the surface of the support rod 5, and vertical rods 19 are fixedly connected to the bottom of each of the four corners of the support frame 18.

[0023] As a technical optimization of this utility model, by setting a support frame 18 fixedly connected to the surface of the support rod 5 and vertical rods 19 at the bottom of the four corners of the support frame 18, the gripping part 6 of the robot arm can be supported and stabilized. The support frame 18 can distribute the pressure generated by the robot arm during operation, making the overall structure more stable, reducing shaking and deviation, ensuring the accuracy and stability of the robot arm in grasping objects, and improving work quality and efficiency.

[0024] refer to Figure 1 The bottom of the vertical rod 19 has a groove, and a ball bearing 20 is rolled inside the groove. The surface of the ball bearing 20 is in contact with the surface of the operating table 4.

[0025] As a technical optimization of this utility model, by setting a ball bearing 20 that is rolled in the groove at the bottom of the vertical rod 19 and fits against the surface of the operating table 4, the ball bearing 20 can reduce the friction between the vertical rod 19 and the operating table 4 during the movement of the robot arm, making the movement of the robot arm smoother and more flexible, reducing energy consumption, and also reducing wear on the surface of the operating table 4, thus extending the service life of the equipment.

[0026] refer to Figure 4 The right end of the positioning bolt 17 is threaded with a nut 21, and the left side of the nut 21 is fixedly connected with an anti-loosening washer 22. The left side of the anti-loosening washer 22 is in contact with the right side of the assembly base 1.

[0027] As a technical optimization of this utility model, by setting a nut 21 with a threaded connection on the right end of the positioning bolt 17 and an anti-loosening washer 22 on the left side of the nut 21, the positioning bolt 17 can be effectively prevented from loosening. During the operation of the robot, a certain amount of vibration will be generated. The anti-loosening washer 22 can increase the friction between the nut 21 and the assembly base 1, making the nut 21 less likely to loosen, thereby ensuring the stability of the connection between the positioning plate 13 and the assembly base 1, ensuring the firmness of the robot assembly structure, and improving the reliability of the equipment.

[0028] refer to Figure 4 T-shaped slide bars 23 are fixedly connected to the front and rear sides of the left and right sides of the structural box 2. T-shaped grooves 24 that cooperate with the T-shaped slide bars 23 are opened on the front and rear sides of the inner side of the positioning plate 13. The surface of the T-shaped slide bar 23 is slidably connected to the inner wall of the T-shaped groove 24.

[0029] As a technical optimization of this utility model, by setting the T-shaped slide bars 23 on the left and right sides of the structural box 2 to cooperate with the T-shaped groove 24 on the inner side of the positioning plate 13, the positioning plate 13 is made more stable and smooth during movement. The sliding connection between the T-shaped slide bars 23 and the T-shaped groove 24 can limit the movement direction of the positioning plate 13, prevent it from shifting or shaking during movement, and ensure that the positioning plate 13 can be accurately inserted into the insertion groove 14 of the assembly base 1, further improving the accuracy and stability of the robot assembly.

[0030] refer to Figure 4 A rubber pad 25 is fixedly connected to the center of the top of the assembly base 1, and the top of the rubber pad 25 is attached to the bottom of the structure box 2.

[0031] As a technical optimization of this utility model, by setting a rubber pad 25 at the top center of the assembly base 1, the rubber pad 25 can play a role in buffering and shock absorption when the structural box 2 is in contact with the assembly base 1. When the robot arm is working, it will generate a certain amount of vibration and impact force. The rubber pad 25 can absorb this energy, reduce damage to the assembly base 1 and the structural box 2, and at the same time reduce noise, improve the comfort of the working environment, and extend the service life of the equipment.

[0032] The working principle and usage process of this utility model are as follows: First, fix the electric slide rail assembly 3 on the operating table 4, then install the assembly base 1 on the output end of the electric slide rail assembly 3. Next, place the structure box 2 above the assembly base 1, rotate the rotating wheel 11. When the rotating wheel 11 rotates, it drives the second bevel gear 10 to rotate via the round rod 9. The rotation of the second bevel gear 10 drives the first bevel gear 8 to rotate, causing the lead screw 7 to rotate and move the nut seat 12 downwards. When the nut seat 12 moves downwards, it drives the two positioning plates 13 on its left and right sides to move downwards simultaneously, thereby inserting the positioning plates 13 into the insertion slots 14 of the assembly base 1. When the through hole 16 below the positioning plate 13 connects with the positioning pin groove 15 of the assembly base 1, insert the positioning bolt 17 into the positioning pin groove 15 and the through hole 16. The positioning bolt 17 is fixed by the nut 21, thereby fixing the structural box 2 to the assembly base 1 and completing the assembly of the robot. The robot gripper 6 is moved by the electric slide rail assembly 3 to perform gripping operations (the electric slide rail assembly 3 and the robot gripper 6 are both existing mature technologies, so their working principles will not be described in detail). When the robot needs to be maintained or replaced, the nut 21 is loosened with a wrench and removed from the right end of the positioning bolt 17. The positioning bolt 17 is then pulled out, and the rotating wheel 11 is rotated in the opposite direction, causing the screw 7 to rotate in the opposite direction, which drives the nut seat 12 to move upward, thereby removing the positioning plate 13 from the insertion slot 14. This separates the structural box 2 from the assembly base 1 and completes the disassembly work, avoiding the cumbersome and potentially problematic traditional methods.
