AI Technical Summary
During clamping, the existing mechanical clamping jaws are uneven in the cylinder supply pressure, resulting in inconsistent cylinder driving and unable to stably clamp the object.
A synchronous positioning mechanism is adopted, including a double-sided rack, gear and slider. The double-sided rack drives the gear inverted by the first cylinder, and the slider drives the gripping plate movement to realize the synchronous and coordinated clamping of the gripping plate, and adapts to different objects through pneumatic suction cup and friction plate adjustment.
The synchronous and coordinated clamping of the gripping plate is realized to ensure stable clamping of objects, adapt to the needs of different object sizes, and avoid the problem of inconsistent cylinder drive.
