A horizontal cam servo press driven by multiple motors

Abstract

A multi-motor-driven, horizontally placed end face cam servo press, including an upper body, two servo motors are symmetrically installed on the upper body, the output shaft of the servo motor is equipped with a small gear, and the two small gears are connected to the large gear. Cooperate, the large gear is connected to the shaft, the shaft is connected to the upper body, the large gear is connected to the end face cam, the end face cam cooperates with the upper end of the guide plunger type push rod, and the lower end of the guide plunger type push rod is connected to the active link. The connecting rods are respectively connected with the upper connecting rod and the lower connecting rod. The lower connecting rod is connected with the push rod, the adjusting screw and the slider. The small gear is driven by the servo motor to rotate, and the small gear drives the end face cam to move through the large gear, and then drives the guide plunger type push rod to do reciprocating linear motion, and drives the slider to move through the active connecting rod, upper connecting rod, lower connecting rod and push rod After the forging is completed, the invention has high rigidity and strength, and the working characteristics of the motor are significantly improved.

Description

technical field [0001] The invention belongs to the technical field of servo presses for mechanical forming equipment, and in particular relates to a multi-motor-driven, horizontally placed end face cam servo press. Background technique [0002] The servo press has high processing precision, can realize precise control, and has high production efficiency. The body of the servo press needs to withstand the forces and moments generated during the processing, and it is the basis for installing other components of the servo press, so it needs to have sufficient strength and rigidity. At present, in the existing servo presses at home and abroad, the rotary motion of the motor is converted into the linear reciprocating motion of the slider by the nut screw or screw nut mechanism after deceleration, thereby realizing the forging function. The transmission chain of the servo press with this structure is too long and complicated, so it is difficult to process and assemble and the tr...

AI Technical Summary

Problems solved by technology

The transmission chain of the servo press with this structure is too long and complicated, so it is difficult to process and assemble and the transmission efficiency is low

At the same time, the up and down movement of the slider requires the motor to start and stop frequently and to rotate forward and reverse, which makes the motor work in a state of low efficiency for a long time
