Self-switching gripper arm structure using handling robot in narrow environment

Abstract

The invention provides a self-switching fixture arm structure for a handling robot used in a narrow environment, including a base; a rotation adjustment structure is installed on the base, and an electric telescopic rod, a telescopic rod and an adjustment arm are installed on the rotation adjustment structure; the electric telescopic rod A clamping structure is installed on the head end of the telescopic rod, and two driving structures are installed on the clamping structure; the adjustment arm includes a gear row, and the two adjustment arms are symmetrically fixedly connected to the gear, and each adjustment arm is welded with a gear row ;When the electric telescopic rod shrinks and drives the driving structure to move downward, the gear sleeve and the gear row mesh, and at this time the clamping arm is in a rotating state; the two driving structures are set in mirror images, and when the gear sleeve and the gear row on the driving structure After the meshing is completed, the adjustment arm rotates at an angle of 90 degrees. In the narrow environment of the present invention, the self-switching fixture arm structure of the handling robot is used to realize the problem of self-switching of various fixture arms without using a motor drive, and realizes the accuracy of adjusting the arm switching.

Description

technical field [0001] The invention belongs to the technical field of handling robots, and more specifically relates to a self-switching clamp arm structure for handling robots used in narrow environments. Background technique [0002] With the continuous development of industrial automation, mechanical clamping arms are widely used. In various industrial production fields, mechanical clamping arms are often used to clamp objects, which not only reduces labor intensity, but also greatly improves production efficiency. Now Most of the mechanical clamping arms have complex structures and expensive manufacturing costs. [0003] For example, patent CN201711424431.0 discloses a mechanical clamping arm, including a fixed plate, a slider, a connecting rod, a spring, a first clamping piece and a second clamping piece, in the middle of the fixed plate and along the fixed A bar-shaped hole is provided in the direction of the plate length, the slider is clamped in the bar-shaped hole...

AI Technical Summary

Problems solved by technology

[0008] The purpose of the present invention is to provide a self-switching clamp arm structure using a handling robot in a narrow environment, to solve the problem that the existing clamping arm is mostly realized by setting a plurality of clamping arms on a rotating disk in order to realize the switching of the clamping arm. It needs to be driven by a motor when switching fixtures, and the cost is high, and the installation of multiple fixture arms at the same time takes up a lot of space, which is not suitable for narrow environments
