Description

Technical Field

[0001] The utility model relates to the technical field of robot arms, in particular to an industrial robot arm rotating device. Background Art

[0002] Industrial robots are multi-joint manipulators or multi-degree-of-freedom machine devices widely used in the industrial field. They have a certain degree of automation and can achieve various industrial processing and manufacturing functions by relying on their own power and control capabilities. At present, industrial robots are widely used in various industrial fields such as electronics, logistics, and chemicals.

[0003] Currently, existing industrial robot arms often need to clamp and hoist some heavy objects when in use. When the robot arm drives the heavy objects to rotate, the inertia force of the heavy objects reacts on the motor drive shaft. After a long time of use, it is easy to cause damage to the robot arm's rotation drive motor, affecting the service life of the motor. Utility Model Content

[0022] See also Figure 1-3 The utility model provides an industrial robot arm rotating device, including a base 1, a positioning frame 2 is arranged on the top of the base 1, a motor 4 is fixedly connected to the center of the top of the base 1, and support columns 3 are fixedly connected to the four corners between the base 1 and the positioning frame 2, so as to facilitate the positioning of the driving motor 4.

[0023] The driving shaft of the motor 4 passes through the positioning frame 2 and is fixedly connected to the base 5. The top of the base 5 is fixedly connected to a mechanical arm 6. The top of the positioning frame 2 is fixedly connected to a buffer plate 7. An annular groove 8 is provided on the top of the buffer plate 7. A counterweight block 9 is slidably connected inside the annular groove 8. A magnet 10 is embedded in the inner wall of the annular groove 8. The counterweight block 9 is made of iron material. The magnet 10 and the counterweight block 9 are attracted by magnetic force to offset the inertial force when the weight rotates. There are a number of magnets 10, and the magnets 10 are evenly distributed in a ring shape on the inner wall of the annular groove 8 to facilitate attraction with the counterweight block 9, generating resistance to buffer the inertial force when the weight rotates.

[0024] Two slides 11 are fixedly connected to the bottom of the base 5, and a spring 12 is fixedly connected between the slide 11 and the counterweight 9. The bottom of the slide 11 is slidably connected to the bottom of the annular groove 8. When the robot arm 6 rotates, it is easy to drive the slide 11 to slide in the annular groove 8, and by squeezing the spring 12, it is easy to buffer the inertia force of the rotation of the heavy object.

[0025] When in use, the motor 4 is connected to an external power source and started, and the motor 4 drives the base 5 to rotate, thereby driving the mechanical arm 6 to rotate to perform industrial lifting or processing operations.

[0026] When the robotic arm 6 rotates, it drives the two slides 11 to move. The slides 11 slide in the annular groove 8 and compress the springs 12 on both sides of the slides 11. When the springs 12 reach the maximum elastic limit, they can just push the counterweight 9 out of the attracted state with the magnet 10. At this time, the counterweight 9 is separated from the attraction with the magnet 10 and then is attracted with the next magnet 10 at a certain distance. At this time, the spring 12 has a deformable distance again and continues to deform, and repeats this process. When the object clamped by the robotic arm 6 is heavy, it is convenient to offset and buffer the inertial force generated by the heavy object when the robotic arm 6 rotates, thereby greatly reducing the damage to the motor 4 caused by the inertial force of the heavy object when it rotates.

[0027] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
