Abstract

The utility model discloses a metal bar rough machining automatic feeding and discharging mechanical arm operating table which comprises a base, a table plate, a supporting column, a carrying plate, a linear sliding rail, a sliding block, a first electric push rod, a top stretching rod, a positioning pin, a feeding and discharging carrier and a second electric push rod, and the table plate is fixedly installed on the base through the supporting column. Due to the fact that the metal bar blanks are jacked and exposed one by one through the jacking and extending rod, a mechanical arm of the mechanical arm can conveniently conduct grabbing, feeding and rough machining operation on the metal bar blanks, and the problem of interference and collision between the mechanical arm and adjacent workpieces of the metal bar blanks to be grabbed is solved. The arrangement distance between the two blind holes in the feeding and discharging carrier can be shortened, the minimum distance can be set to be 3-4 cm under the condition that the installation positions of the first electric push rods do not interfere with one another, and therefore more metal bar blanks can be placed in the blind holes of the feeding and discharging carrier of the same size at a time, and the production efficiency is improved. Therefore, the material changing frequency of the feeding and discharging carrier is reduced, and the machining operation efficiency is improved.

After the processing is completed, the metal bars are placed vertically back on the operating table to realize automated operation. At present, there needs to be a distance of more than 10 cm between the edges of the metal bars placed on the operating table. Otherwise, when the robot grabs the metal bars to be loaded, it will interfere with and collide with the adjacent bars. This leads to a significant reduction in the number of metal bars placed on the existing operating table, and the operator needs to frequently replace the operating table containing the metal bar blanks.
