Description

Technical Field

[0001] The utility model relates to a fixing mechanism, in particular to a robot cable free movement fixing mechanism. Background Art

[0002] Currently, on four-axis robots, cables (such as air lines, sensor cables, and network cables) must be routed from the chassis to the Z-axis end of the robot. The air lines are inserted from the Z-axis, while other cables are secured to the Z-axis end from the side. Because robots frequently rotate up and down, left and right, and forward and backward, these cables can easily collide with the robot or other components, causing damage. To address this, the inventors designed a free-motion cable securing mechanism for robots. Utility Model Content

[0003] The purpose of the utility model is to provide a robot cable free movement fixing mechanism, which has the advantages of simple structure, reasonable design, easy assembly, and can effectively reduce cable damage and extend the service life of the cable, thereby solving the problems raised by the above technical background.

[0004] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a robot cable free movement fixing mechanism, comprising a base, a first bearing, a second bearing, a rotating shaft, a washer, a lower cable clamp and an upper cable clamp, wherein the base protrudes upward to form a convex column, and the convex column is a cavity structure with openings at the upper and lower ends and a hollow interior, a tightening portion is provided in the cavity, and a first mounting step and a second mounting step are formed at the upper and lower ends of the tightening portion, the first bearing and the second bearing are respectively installed on the first mounting step and the second mounting step, the rotating shaft passes through the second bearing and the first bearing in sequence from bottom to top and is plugged into the washer, the lower cable clamp is provided on the washer, and the lower cable clamp and the rotating shaft are fixedly connected by a detachable screw, the upper cable clamp is fixedly connected to the lower cable clamp, and a circular cable hole for the cable to pass through is formed.

[0005] Preferably, the base is provided with two fixing holes, and the two fixing holes are symmetrically distributed about the central axis of the base.

[0006] Preferably, the first bearing and the second bearing are of the same size.

[0007] Preferably, the rotating shaft is a cylindrical structure with a hollow interior, and the rotating shaft is coaxially arranged with the first bearing, the second bearing and the washer.

[0008] Preferably, the cable lower clamping ring and the cable upper clamping ring have the same size, and both the cable lower clamping ring and the cable upper clamping ring are semicircular in shape.

[0010] 1. The utility model provides a robot cable free movement fixing mechanism, which includes a base, a first bearing, a second bearing, a rotating shaft, a washer, a cable lower clamp and a cable upper clamp. The overall structure is simple and the design is reasonable. The rotating shaft passes through the second bearing and the first bearing from bottom to top and then connects with the washer. The cable lower clamp and the rotating shaft are fixedly connected by a detachable screw. When the rotating shaft rotates, the cable lower clamp and the cable upper clamp connected to the cable lower clamp can be driven to rotate 360 ​​degrees. When the robot rotating cable swings left and right, the cable lower clamp and the cable upper clamp used to fix the cable will rotate with the robot movement direction, thereby effectively reducing cable damage and extending the service life of the cable.

[0011] 2. The utility model forms a convex column by protruding upward from the base. The convex column is a cavity structure with openings at the upper and lower ends and a hollow interior.
