Asymmetry sliding groove lever type mechanical arm

Abstract

The invention provides an asymmetry sliding groove lever type mechanical arm, and belongs to the technical field of automation. The asymmetry sliding groove lever type mechanical arm comprises a lifting support, a horizontal sliding base, a fixed finger, an inverted-L-shaped movable finger and a hydraulic drive system. The upper end of a lifting piston rod is connected with the lifting support. The horizontal sliding base is arranged on a sliding guide rail in a sliding manner. A horizontal movement lead screw and a lead screw nut are in threaded connection. The fixed finger is arranged at oneend of a finger bearing base through a fastening screw. The middle end of the inverted-L-shaped movable finger is hinged to the other end of the finger bearing base through a finger pin shaft. A boltis inserted in a U-shaped groove of the inverted-L-shaped movable finger. One end of an oil pump of the hydraulic drive system is connected with an oil tank, and the other end of the oil pump is connected with a valve port A of a three-position four-way reversing valve Q, a valve port E of a three-position four-way reversing valve R and an overflow valve. According to the asymmetry sliding groovelever type mechanical arm, workpiece collisions in the workpiece clamping process are reduced, the centering and clamping precision of a workpiece are effectively improved, the structure is reasonable, and the automation degree is high.

Description

technical field [0001] The invention relates to the technical field of automation, in particular to an asymmetric chute lever type manipulator. Background technique [0002] Automation (Automation) refers to the machine equipment, system or process (production, management process) without the direct participation of people or fewer people, according to people's requirements, through automatic detection, information processing, analysis and judgment, manipulation and control, to achieve the expected target process. Automation technology is widely used in industry, agriculture, military, scientific research, transportation, commerce, medical care, services and households. The use of automation technology can not only liberate people from heavy physical labor, part of mental work, and harsh and dangerous working environments, but also expand human organ functions, greatly improve labor productivity, and enhance human ability to understand and transform the world. . Therefore...

AI Technical Summary

Problems solved by technology

At present, the common lever-type manipulator will collide with the workpiece due to its large swing range, which will affect the centering and clamping accuracy of the workpiece.
