[0002] In the industrial production process, robot arms are often used to transfer materials. Among them, the robot arm needs to be fixedly installed at a specified position, and then programmed to move along the set running trajectory.

[0003] When installing the robot arm, a corresponding connection base is generally used. During installation, the connection base is first fixedly installed on the ground, and then the robot arm is installed on the connection base. The Chinese utility model patent with the application number 202223381190.5 discloses that "the positioning pin under the robot arm base is inserted into the counterbore at the top of the bearing column, the worm is driven to rotate, the rotation of the worm will drive the worm gear to rotate, thereby driving the connection cylinder to rotate, and the connection cylinder will drive the connecting plate to rotate until the mounting holes on the connecting plate correspond to the mounting holes on the robot arm base. Then, the fixing bolts can be screwed into the mounting holes on the connecting plate and the robot arm base to fix the robot arm to the connecting plate." In the process of using this solution, the manipulator and the seat body are fixed through multiple positions, thereby ensuring the stability between the manipulator and the base. However, in this way, when disassembling and repairing between the manipulator and the base, it is often not possible to disassemble conveniently, nor can the manipulator and the base be fixed at one time, resulting in low efficiency in fixing and disassembling between the manipulator and the base, and relatively cumbersome operations. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a connection base for a mechanical automation robot arm to solve the technical problems mentioned in the above background technique.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme:

A connecting plate is fixedly connected to the bottom end of the manipulator body. A guiding block adapted to the guiding groove is fixedly connected to the bottom of the connecting plate. A connecting structure passing through the through hole is fixedly connected to the bottom of the connecting plate. By driving the rotating sleeve to rotate, the fixing of multiple groups of connecting structures to the seat body is realized simultaneously.

[0007] As a further description of the above technical solution:

[0008] The connecting structure includes a screw rod, a connecting sleeve and a nut. The screw rod is fixedly connected to the bottom of the connecting plate.

[0011] As a further description of the above technical solution:

[0012] A worm gear is fixedly sleeved on the bottom end of the rotating sleeve. A driving motor is fixedly installed in the seat body, and an output shaft of the driving motor is drivingly connected with a worm meshed with the worm gear.

[0013] As a further description of the above technical solution:

[0014] The guiding block is an inverted frustum of a pyramid, and the guiding groove is a groove structure in surface contact adapted to the frustum of the pyramid.

[0015] As a further description of the above technical solution:

Under the self-locking action of the worm gear and the threads, the fixed connection between the manipulator body and the seat body is realized. If it is necessary to remove the manipulator body, the driving motor is started to reverse to make the connecting sleeve disengage from the nut. In this way, the simplicity of fixing between the manipulator body and the seat body is ensured, the convenience of fixing and disassembling during the maintenance of the manipulator body is ensured, the high efficiency of the fixed docking between the seat body and the manipulator body is ensured, the complexity of multi-point fixing between the seat body and the manipulator body is simplified, and a good operation mode for docking between the seat body and the manipulator body is improved.

[0019] 2.

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] Please refer to Figures 1-5, the present utility model provides a technical solution: a mechanical automation robot arm connecting base, including a base body 1 and a robot arm body 4. Four sides of the bottom side of the base body 1 are fixedly connected with fixing ears 2, and mounting holes are provided on the fixing ears 2. A fixing column 6 is fixedly connected to the middle of the base body 1, and a rotating sleeve 5 is rotatably mounted on the fixing column 6. A guiding groove 601 is provided on the fixing column 6, and through holes 101 evenly distributed around the fixing column 6 are provided on the base body 1. A connecting plate 3 is fixedly connected to the bottom end of the robot arm body 4, and a guiding block 12 adapted to the guiding groove 601 is fixedly connected to the bottom of the connecting plate 3. The guiding block 12 is an inverted frustum of a pyramid, and the guiding groove 601 is a groove structure with surface-to-surface contact adapted to the frustum of a pyramid. When hoisting and docking the robot arm body 4 with the base body 1, when the frustum-of-a-pyramid-shaped guiding block 12 is docked with the guiding groove 101, as long as the guiding block 12 can enter the guiding groove 101, due to structural limitations, it can be positioned regardless of the orientation of hoisting the robot arm body 4 and docking it with the base body from any of the four directions of east, west, south, and north. That is, the screw 14 and the connecting sleeve 11 can accurately pass through the through hole 101 without precisely adjusting the position of the connecting plate 3 to allow the screw 14 and the connecting sleeve 11 to pass through the through hole 101, simplifying the alignment operation during installation and making the installation process simpler.

[0029] Specifically, such as Figures 3-5As shown in the figure, the screw rod 14 is fixedly connected to the bottom of the connecting plate 3. The connecting sleeve 11 is screwed onto the outside of the screw rod 14 through threads. The nut 13 is fixedly connected to the position on the base body 1 that is coaxial with the through hole 101. The lower end of the connecting sleeve 11 is screwed into the nut 13 through threads. The top end of the rotating sleeve 5 is fixedly sleeved with a gear disk 7. The upper end of the connecting sleeve 11 has a gear structure meshed with the gear disk 7. The bottom end of the rotating sleeve 5 is fixedly sleeved with a worm gear 8. A driving motor 10 is fixedly installed in the base body 1. The output shaft of the driving motor 10 is drivingly connected with a worm 9 meshed with the worm gear 8. After the screw rod 14 and the connecting sleeve 11 pass through the through hole 101, the fixing column 6 first contacts the connecting plate 7 and plays a supporting role for the robotic arm body 4. After that, the driving motor 10 is started to drive the worm 9 to rotate. The screw rod 9 drives the worm gear 8 to drive the rotating sleeve 5 and the gear disk7 to rotate. The gear disk 7 is meshed with the gear structure on the connecting sleeve 11. Furthermore, the gear disk 7 drives multiple connecting sleeves 11 to rotate synchronously. According to the principle of screw drive, the connecting sleeves 11 simultaneously spiral down along the surface of the screw rod 14. The bottom end of the connecting sleeve 11 is screwed into the nut 13. Under the action of the worm and worm gear and screw self-locking, the fixed connection between the robotic arm body 4 and the base body 1 is realized. If the robotic arm body 4 needs to be removed, the driving motor 10 is started to reverse so that the connecting sleeve 11 is disengaged from the nut 13. In this way, the simplicity of fixing the robotic arm body 4 to the base body 1 is ensured, the convenience of fixing and disassembling the robotic arm body 4 during maintenance is ensured, the high efficiency of the fixed docking between the base body 1 and the robotic arm body 4 is ensured, and the tediousness of multi-point fixing between the base body 1 and the robotic arm body 4 is simplified, improving the good operation method when the base body 1 and the robotic arm body 4 are docked.

[0030] Working principle: During use, first, place the base body 1 at the installation location to be installed. After that, use pins or expansion bolts to fix the fixing ear 2 to the ground. At this time, the robotic arm body 4 can be lifted. Then, sink the guide block 12 at the bottom of the connecting plate 3 into the guide groove 601, so that the screw rod 14 and the connecting sleeve 11 pass through the through hole 101. After that, start the driving motor 10 to drive the worm 9 to rotate. The screw rod 9 drives the worm gear 8 to drive the rotating sleeve 5 and the gear disk 7 to rotate. The gear disk 7 is meshed with the gear structure on the connecting sleeve 11. Furthermore, the gear disk 7 drives multiple connecting sleeves 11 to rotate synchronously. According to the principle of screw drive, the connecting sleeves 11 simultaneously spiral down along the surface of the screw rod 14. The bottom end of the connecting sleeve 11 is screwed into the nut 13. Under the action of the worm and worm gear and screw self-locking, the fixed connection between the robotic arm body 4 and the base body 1 is realized. If the robotic arm body 4 needs to be removed, the driving motor 10 is started to reverse so that the connecting sleeve 11 is disengaged from the nut 13. Also, the tediousness of multi-point fixing between the base body 1 and the robotic arm body 4 is simplified, improving the good operation method when the base body 1 and the robotic arm body 4 are docked.
