Truss mechanical arm for bearing inner rings

Abstract

The invention relates to a truss mechanical arm for bearing inner rings. The truss mechanical arm comprises a frame type vertical beam movably installed on a truss, the upper end of the vertical beam is provided with a rotating shaft, and the outer end of the rotating shaft is provided with clamping claws, wherein the clamping claws are used for clamping or loosening the bearing inner rings and can be driven by the rotating shaft to turn over. Each clamping claw comprises a supporting sleeve and a pressing block, wherein the supporting sleeve is arranged on the inner hole wall of the corresponding bearing inner ring in a supported manner, and the pressing block is pressed to the outer wall of the corresponding bearing inner ring and matched with the corresponding supporting sleeve to grab the corresponding bearing inner ring. Each pressing block is provided with an arc face consistent with the outer circumference of the corresponding bearing inner ring, and the middle of each arc face is provided with an inwards-concave opening which prevents falling of the corresponding bearing inner ring caused by untight clamping. The vertical beam is provided with a drive shaft in a transversely penetrated manner, and the drive shaft drives the rotating shaft to rotate. Through the arrangement of the two sets of clamping claws, two bearing inner rings can be grabbed at a time, and work efficiency is improved; and a three-point contact clamping manner is adopted for clamping of the bearing inner rings, the clamping steadiness is effectively improved, the grabbed bearing inner rings can be turned over to any direction according to technological requirements, and machining and processing are facilitated.

Description

technical field [0001] The invention relates to a truss manipulator used in a bearing inner ring. Background technique [0002] In the automatic production process of bearings, manipulators are generally used for loading and unloading of workpieces. For the manipulators used for loading and unloading the inner ring of bearings, the manipulators used for loading and unloading the inner ring of the bearing are generally grasped to the position required by the process by means of inner hole support and outer ring clamping. The clamping method often causes mutual interference due to too many clamping points during actual operation, resulting in insufficient clamping firmness. At the same time, the grasping of a single mechanical claw also makes the operation efficiency low. Contents of the invention [0003] The technical problem to be solved by the present invention is: in order to overcome the deficiencies in the prior art, the present invention provides a truss manipulator ...
