Description

Technical Field

[0001] The utility model relates to the technical field of industrial robots, in particular to an industrial robot connecting base which is convenient to adjust the angle. Background Technique

[0002] An industrial robot refers to a multi-joint manipulator or a multi-degree-of-freedom machine device used in the industrial field. They can automatically execute work tasks. Such robots rely on their own power systems and control systems to complete various predetermined functions and can accept manual instructions or run according to preset programs. The efficient operation of industrial robots depends on the design of their connecting bases. The connecting base not only provides a stable basic support but also can adjust the position and angle of the robot when necessary to ensure that the robot can accurately and stably execute tasks in different working environments.

[0003] The "industrial robot connecting base which is convenient to adjust the angle" disclosed in the patent application with the application number "202122815161.4" includes a base body. A regulating box is arranged at the bottom of the base body. Universal wheels are fixedly connected to the four corners of the bottom of the regulating box. A rotating column extending outside the top of the regulating box is rotatably connected to the inner wall of the bottom of the regulating box. The top of the rotating column is fixedly connected to the center of the bottom of the base body. A rotating gear is fixedly connected to the circumferential outer wall of the rotating column. A pushing mechanism is arranged on the inner wall of the regulating box, and a connecting block is fixedly arranged at one end of the pushing mechanism. A rack is fixedly connected to the surface of the connecting block close to the rotating gear, and the rack meshes with the rotating gear. The advantage of this device is that it is convenient to adjust the angle of the base.

[0004] However, the above design has certain limitations, specifically manifested as follows: Using the method of horizontal movement of the rack to drive the rotation of the rotating column not only increases the installation space required by the equipment but also limits the application of the base in a narrow environment. In addition, since the rotating column is the main support point, the contact area between it and the base body is small, resulting in the possible shaking of the industrial robot during high-speed operation or when carrying a heavy load. The instability of the support increases potential safety hazards, such as possible tipping during operation, which may cause equipment damage or more serious production accidents.
