Robot tail end force doubling pneumatic scissor hand

Abstract

The invention relates to a robot tail end force doubling pneumatic scissor hand comprising an air cylinder, a base mounted on the air cylinder, a shearing knife seat and a shearing blade. The shearing knife seat and the shearing blade are mounted on the base, the shearing blade is detachably mounted on the shearing knife seat, the shearing knife seat is connected to an air cylinder piston rod, the two ends of the bottom of the base upwards protrude to form two parallel supporting stand columns, the front ends of the supporting stand columns are provided with blade abutting portions, the supporting stand columns and the blade abutting portions form a shearing space, the two supporting stand columns clamp the shearing knife seat, and the air cylinder piston rod pushes the shearing knife seat to drive the shearing blade to abut against the blade abutting portions in the directions of the supporting stand columns. The robot tail end force doubling pneumatic scissor hand has the beneficial effects that the structure of an original robot tail end force doubling pneumatic scissor hand is changed, an injection water nozzle is conveniently shorn, the problem of insufficient air pressure is solved by the double air cylinder manner, and the shearing force is ensured.

Description

technical field [0001] The invention relates to the technical field of robot scissors, in particular to a robotic end double force pneumatic scissors hand. Background technique [0002] In the prior art, manual cutting is usually used for cutting the injection nozzle, which has relatively high requirements for workers, and it is easy to cause damage to the product during the cutting process, resulting in poor cutting effect and low work efficiency. In recent years, with the continuous optimization of the process, pneumatic scissors are used to cut the injection nozzle. The existing pneumatic scissors are composed of a cylinder and a pair of pliers. Since the annotated nozzle is usually narrow and connected to the injection molded part, the traditional scissors are scissor-style, and it is no problem to extend into the nozzle to cut the nozzle; in the prior art, the cutter head is usually ground so that it can Enter the cutting position to cut, but the actual use effect is n...

AI Technical Summary

Problems solved by technology

Since the annotated nozzle is usually narrow and connected to the injection molded part, the traditional scissors are scissor-style, and it is no problem to extend into the nozzle to cut the nozzle; in the prior art, the cutter head is usually ground so that it can Enter the cutting position to cut, but the actual use effect is not good

At the same time, the air source of the cylinder used by most manufacturers is 6 standard atmospheres, and the standard tooling frame matched with the double force pneumatic scissors at the end of the robot, so a cylinder with a piston diameter of 63mm is usually used; Due to the pressure of the air source and the diameter of the piston, the shear force is insufficient, and multiple shears are often required, which affects product quality and appearance

If the diameter of the cylinder piston is only increased, it cannot be matched with the tooling frame and cannot be installed, and it also greatly increases the production cost
