Four-axis linkage mechanical arm for feeding and stamping

Abstract

The invention discloses a four-axis linkage mechanical arm for feeding and stamping. The four-axis linkage mechanical arm comprises an electromagnetic attracting disc, a mounting cylinder, an axial mechanism I and an axial mechanism II, wherein the axial mechanism I and the axial mechanism II are positioned in the mounting cylinder. A rotation axial line is arranged at the center of the mounting cylinder. The electromagnetic attracting disc is driven by the axial mechanism I to move vertically and perpendicularly, and is driven by the axial mechanism II to rotate around the rotating axial lineof the mounting cylinder. The axial mechanism I is a hollow cylinder and is matched with the axial mechanism II. The hollow cylinder is driven by the axial mechanism II to rotate, so that the electromagnetic attracting disc is driven by the axial mechanism II to rotate around the rotation axial line of the mounting cylinder. The center of gravity of the axial mechanism II is low, so that the axial mechanism II is good in transmission stability. The electromagnetic attracting disc is driven by the four axial mechanisms to carry out axial rotation, so that dies attracted are driven by the electromagnetic attracting disc to adjust positions, next operation is facilitated, and the practicability is strong.

Description

technical field [0001] The invention relates to the technical field related to moulds, in particular to a four-axis linkage manipulator for feeding and stamping. Background technique [0002] The manipulator is an automatic device with the function of grabbing and moving workpieces used in the automatic mold production process. It is a new type of device developed in the mechanized and automated production process. The manipulator can be used to replace workers in dangerous and boring tasks. The work can increase the productivity of the factory while reducing the labor intensity of the workers. [0003] In the existing technology, the patent application number is 201721363346.3, and the patent name is a long-arm three-axis loading and unloading stamping manipulator. The manipulator performs feeding and stamping operations on the mold. This patent has the following disadvantages: [0004] 1. The rotation mechanism of this patent is unreasonably set, and the setting position ...

AI Technical Summary

Problems solved by technology

[0004] 1. The rotation mechanism of this patent is unreasonably set, and the setting position is relatively high, resulting in a high center of gravity of this patent and unstable rotation of the long arm feeding shaft;

[0005] 2. The patented rotating mechanism and long-arm feeding mechanism are two sets of mechanisms with completely independent motors and transmission devices. The mechanical structure is complicated, which leads to cumbersome maintenance and repair of the equipment;

[0006] 3. The adsorption device of this patent does not have the function of rotation. The adsorption device can only absorb the mold. The position of the mold itself needs to be adjusted twice by the main body of the manipulator (for example, the mold needs to be placed in the specified slot, and the angle must be aligned before entering slot), inconvenient to use
