Description

Technical Field

[0001] The utility model relates to the technical field of robots, in particular to a micro robot driving joint. Background Art

[0002] Since the 1960s, robots have been used more and more widely in various industries, especially in the fields of machinery and aerospace. These traditional robots are installed and fixed in specific positions, and their workflows are pre-designed by humans to perform specific operations repeatedly. With the continuous expansion of the application fields of robots, traditional industrial robots in many cases not only have to perform specific operations, but also some other operations and perform some multi-dimensional actions. When performing multi-dimensional actions, driving joints are required to drive the robot. The driving joints are generally composed of motors, brakes, encoders and reducers, and are connected in series to form driving joints.

[0003] Existing robot drive joints are fixedly connected to the robot body. When the drive joints are damaged after long-term use, they cannot be replaced, which will affect the normal use of the robot. For this reason, we propose a micro robot drive joint. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide a micro robot driving joint, which can replace the damaged driving joint at any time without affecting the normal use of the robot, and can effectively solve the problems in the background technology.

[0007] The disassembly and assembly mechanism includes a threaded column, a lifting plate and a guide rod. Lifting plates are symmetrically arranged below both ends of the robot mounting platform, and threaded holes are opened on the lifting plates. The threaded columns are threadedly connected to the threaded holes, and guide rods are symmetrically arranged on the lifting plates. The guide rods pass through the robot mounting platform and extend upward. A pressure plate is fixedly installed on the upper end of the guide rod, and a turntable is provided at the lower end of the pressure plate. The turntable is movably connected to the robot mounting platform, a driving joint is fixedly installed on the upper end of the turntable, and a mounting shaft is fixedly connected to the lower end of the turntable, and wiring holes are evenly opened on the mounting shaft. Through the setting of the threaded column and the lifting plate, the fixing of the pressure plate to the turntable can be controlled, and then the disassembly and installation of the driving joint can be controlled.

[0008] When the driving joint is damaged, you first need to rotate the threaded column to make it rotate. Through thread transmission, the threaded column can drive the lifting plate to move upward until the lifting plate is detached from the turntable and the rotating disk is twisted. Then the driving joint can be disassembled, and then a new driving joint can be inserted into the robot mounting platform. Then the threaded column is rotated to drive the lifting plate to move downward, and then the driving joint can be fixed through the turntable by the pressure column.

[0009] Furthermore, the turntable has symmetrical through holes on the upper end, and a pressure column is fixedly connected to the lower end of the pressure plate, which is plugged into the through hole. By setting the pressure plate and the pressure column, the turntable can be fixed to the upper end of the robot mounting platform to prevent the turntable from sliding.

[0010] Furthermore, the disassembly and assembly mechanism also includes a mounting plate, a mounting plate is provided on the upper end of the driving joint, threaded holes are evenly opened on the mounting plate and the upper end of the driving joint, and the mounting bolts are threadedly connected to the threaded holes on the mounting plate and the threaded holes on the driving joint. Through the arrangement of the mounting plate and the mounting bolts, the arm connecting plate and the driving joint can be easily fixed.

[0011] Furthermore, it also includes an arm connecting plate, the lower end of the arm connecting plate is fixedly connected to the connecting shaft, and the lower end of the connecting shaft is fixedly connected to the mounting plate. Through the setting of the arm connecting plate, it can be conveniently connected to the mechanical arm.

[0012] Furthermore, the arm connecting plate is evenly provided with mounting holes, and the mounting holes are used in conjunction with the mechanical arm. The provision of the mounting holes can facilitate timely replacement of the mechanical arm.

[0013] Furthermore, it also includes an installation groove and a terminal. The upper end of the robot mounting platform is provided with an installation groove, and the terminal terminals are evenly installed in the installation groove. Through the setting of the terminal terminals, they can be used in conjunction with the wiring holes for easy operation.
