It usually includes a robotic arm or other types of movable devices, equipped with grippers, suction cups, fixtures or other grasping tools, and is used to perform various grasping tasks in automated production lines, warehouse logistics systems, laboratories or other environments. The chassis of the grasping robot is usually the basic structure that supports the entire system. It carries other components of the robot and provides movement and positioning functions.

[0003] Since the chassis generally supports the entire grasping robot, some grasping robots do not have supporting rollers on their chassis, and the chassis is fixed at the use position so that the grasping robot remains stable when in use. However, the grasping robot itself has a large mass, and when moving the grasping robot chassis, it requires the assistance of external equipment for transportation, which makes it time-consuming and laborious for people to adjust the placement of the grasping robot, increasing the difficulty of operation when the grasping robot moves as a whole.

[0004] With respect to the above-mentioned related technologies, the inventor believes that the chassis of the grasping robot fixed at the use position has the defect of being inconvenient to move the overall position of the grasping robot. Therefore, a grasping robot chassis structure is proposed to solve the above-mentioned problem. Utility Model Content

A supporting mechanism is also provided on the lower bottom surface of the supporting chassis 1 for rolling support of the robot body 2.

[0022] By setting the robot body 2 at the use position, when the robot body 2 is moved, the support chassis 1 and the external equipment are fixed to each other, and the two bidirectional screw rods 8 are rotated to drive the connecting member 5 to move along the inner groove 7. The distance between the two connecting members 5 on the outer surface of the single bidirectional screw rod 8 is adjusted, so that the movable connecting member 5 drives the movable support rod 4 to rotate, and then the multiple movable support rods 4 lift the support chassis 1 as a whole, which reflects the adjustment effect of the movable support rod 4 on the distance between the support chassis 1 and the connecting plate 9.
