The invention discloses a truss type loading and unloading
system and method suitable for multi-specification mining
drill bits. The truss type loading and unloading
system comprises a truss type mechanical arm, a flexible gripper installed on the truss type mechanical arm, a loading and positioning device arranged below the truss type mechanical arm and a unloading tray. The flexible gripper comprises an air cylinder, a fixing base arranged on the lower portion of the air cylinder, a lifting base connected to the lower portion of the fixing base and connected with the lower portion of a
piston rod of the air cylinder, two sets of arc-shaped supporting plates hinged to two ends of the fixing base, connecting plates hinged to the lifting base and the supporting plates respectively, and quick-change clamping jaws detachably arranged at the lower ends of the supporting plates. The loading and positioning device comprises a loading worktable, a pre-positioning mechanism arranged on the loading worktable, a
laser positioning mechanism and a rotary displacement mechanism. The flexible gripper can accurately grab the
drill bits, the quick-change clamping jaw is convenient to replace, and the
drill bits of different specifications can be automatically grabbed; A locating and positioning device solves the problems that it is hard to position a blade of the
drill bit and the grabbing position is inaccurate as the heights of the drill bits are inconsistent and the like.
