Description

Technical Field

[0002] Industrial robots are multi-jointed manipulators or multi-degree-of-freedom machines widely used in industrial fields. They are widely applied in various industries such as electronics, logistics, and chemicals. When an industrial robot malfunctions, it needs to be secured before disassembly and repair.

[0003] A search revealed a Chinese patent publication number CN222609674U, which discloses a cylindrical base clamping device for industrial robot maintenance. The device includes a left clamping mechanism and a right clamping mechanism arranged opposite to each other. The left clamping mechanism includes a motor, a clamping plate, a sliding frame, a toothed plate, a gear, and a toothed ring. The right clamping mechanism has the same structure as the left clamping mechanism.

[0004] This patent uses a motor to drive a gear to rotate, and the rotation of multiple gears and a gear ring causes multiple gears to rotate synchronously. The transmission between the gear plate and the gear causes the sliding frame to move the clamping plate toward the industrial robot base to clamp the industrial robot base. However, industrial robot bases come in various shapes, and this patent can only clamp cylindrical bases. When clamping other types of industrial robot bases is required, other types of base clamping devices need to be prepared, which increases the equipment cost. Utility Model Content
