Sheet-metal working mechanical arm for automatically adjusting height of workpiece

Abstract

The invention discloses a sheet-metal working mechanical arm for automatically adjusting the height of a workpiece, comprising an impact molding mechanism, a transfer mechanical arm and a plate lifting support table. The impact molding mechanism comprises an impact molding lower mold and a molding and material loading air cylinder; the transfer mechanical arm comprises a rotation driving spindle, a rotation piece taking swing arm and an electromagnetic piece taking sucking disc; a fixed supporting base, multiple lifting support lead screws and a horizontally driving spindle are arranged below the plate lifting support table; the fixed supporting base is provided with multiple lead screw installing through holes which are arranged vertically in the axial direction, each of the lead screw installing through holes is provided with one of the lifting support lead screws, each of the lead screw installing through holes is provided with a lead screw lifting wheel gear, the outer sides of the lead screw lifting wheel gears are of bevel gear structures, and the horizontally driving spindle is provided with a spindle driving bevel gear that matches the lead screw lifting wheel gears. The sheet-metal working mechanical arm for automatically adjusting the height of a workpiece can realize automatic grabbing and material loading operation of stacked blanking plates.

Description

technical field [0001] The invention relates to the technical field of mechanical processing equipment, in particular to a sheet metal processing manipulator that automatically adjusts the height of workpieces. Background technique [0002] Sheet metal parts are processed from raw materials to finished products, usually including blanking, punching, rough forming, finishing and welding. After the blanking process is completed, the unloaded blanking sheets are piled up on the floor plate or the transfer vehicle, and then transported to the subsequent process, and sent to the stamping die for subsequent punching or forming operations. In subsequent punching or forming operations, the blanked sheet is usually manually fed into a stamping forming or punching die for stamping operations. The operation method of manually grabbing the blanking sheet and feeding it into the forming or punching mold is not only labor-intensive but also low in efficiency, and it is also prone to work...

AI Technical Summary

Problems solved by technology

The operation method of manually grabbing the blanking sheet and feeding it into the forming or punching mold is not only labor-intensive but also low in efficiency, and it is also prone to work-related accidents. Again, the manual operation method is not conducive to accurately controlling the placement position of the blanking sheet. It is easy to cause position errors in stamping or punching

In addition, the existing manipulators that automatically grab the blanking sheet and send it into the forming or punching die can only grab the blanking sheet at a fixed position and height, so manual cooperation is required before each grabbing action of the robot. Place a blanking plate at the grabbing position of the manipulator. The above-mentioned operation method is labor-intensive, and the degree of automation needs to be further improved.
