Four-freedom-degree mechanical arm device

Abstract

A four-freedom-degree mechanical arm device comprises a base, a lifting seat up-down movement driving mechanism, a lifting seat, a sliding table fixing seat rotation driving mechanism, a sliding tablefixing seat, a sliding arm front-back reciprocating driving mechanism, a sliding arm, a mechanical claw and a mechanical claw rotation driving mechanism, wherein the lifting seat up-down movement driving mechanism is arranged on the base; the lifting seat is arranged on the lifting seat up-down movement driving mechanism; the sliding table fixing seat rotation driving mechanism is arranged on thelifting seat; the sliding table fixing seat is connected with the sliding table fixing seat rotation driving mechanism; the sliding arm front-back reciprocating driving mechanism is arranged on the sliding table fixing seat; the sliding arm is arranged on the sliding arm front-back reciprocating driving mechanism in a horizontal cantilever state; the mechanical claw rotation driving mechanism isused for making the mechanical claw rotate and arranged on the sliding arm; and the mechanical claw is arranged at the front end of the sliding arm and connected with the mechanical claw rotation driving mechanism. Labor, time and effort are saved, and safety is guaranteed. It is guaranteed that a to-be-punched workpiece grasped by the mechanical claw can be adjusted at four freedom degrees and accurately put into a die.

Description

technical field [0001] The invention belongs to the technical field of automatic feeding machinery, and in particular relates to a four-degree-of-freedom mechanical arm device. Background technique [0002] In enterprises that stamp and form workpieces, the material to be stamped, such as a plate, is first cut by a cutting device to form a blank of the required or specified size, and then the blank is placed in the lower die on the worktable of the punching device such as a punching machine In the process, the work of the stamping device drives the upper die set at the end of the cylinder column or cylinder column of the stamping device to dive down to the lower die to form a stamped workpiece. [0003] At present, many sheet metal processing enterprises and manufacturers of various mechanical parts still follow the traditional manual feeding mode. The so-called traditional feeding mode refers to: workers manually pick up the parts to be stamped and adjust the orientation of...

Problems solved by technology

However, these patent documents are not limited to exemplifications, and there is no reference value for the automatic loading of workpieces for product stamping and forming manufacturers, because the loading of workpieces to be stamped must at least meet the following requirements: adjust the height of the extracted workpieces to be stamped by the up and down adjustment device The upper and lower heights, the angular position of the extracted parts to be stamped are adjusted by the base plane rotating assembly, the front and rear positions of the extracted parts to be stamped are adjusted by the horizontal reciprocating assembly, and the manipulator claws together with the extracted parts to be stamped along the The angle required for the center to rotate itself
