Quick-change interface device for mechanical arm

Abstract

The quick-change connector device for the mechanical arm comprises an upper shell, a conical head, a lining, a lower flange, a lower shell and an upper flange, a longitudinal sliding block is slidably embedded in one end of the upper shell, the three sides of the top of the longitudinal sliding block abut against the bottom of one end of a holding rod, and the center of the bottom of the longitudinal sliding block is connected to one end of a push rod in a sleeving mode; the other end of the push rod abuts against the center of the top of the wedge-shaped sliding block, the inclined faces of the three sides of the bottom of the wedge-shaped sliding block abut against the outer circumference of the middle section of the rolling column, the rolling column is rotationally embedded in the transverse sliding block, and the transverse sliding block is slidably embedded in the sliding groove. According to the mechanical arm, a holding, pinching and clamping fixed connection mode is adopted, a traditional screw fixed connection mode is replaced, tool-free mounting and dismounting can be achieved, operation is convenient and fast, consumed time is short, the portability of the mechanical arm is improved, the limiting function is achieved, the axial deflection problem between the mechanical arm and the mounting position and between the mechanical arm and a tail end tool in the using process is solved, and the mechanical arm is convenient to use. And normal use of the mechanical arm is ensured.

Description

technical field [0001] The invention relates to the technical field of mechanical arm accessories, in particular to a quick-change interface device for a mechanical arm. Background technique [0002] The robotic arm is an automated technical equipment that imitates part of the functions of the upper limbs of the human body and transports workpieces or supports tools for operation according to predetermined requirements. However, when the existing portable manipulator is working, it is often connected with the installation position by means of screw connection. This method requires special tools such as a wrench during installation or disassembly, which takes a long time to install and disassemble, which seriously affects the portability of the manipulator. In addition, the existing portable manipulators and their end tools are mostly connected by screws, which also has the problems of time-consuming installation and disassembly, poor portability, and no limit function.

AI Technical Summary

Problems solved by technology

However, when the existing portable manipulator is working, it is often connected with the installation position by means of screw connection. This method requires special tools such as wrenches when installing or dismounting. The installation and disassembly takes a long time, which seriously affects the portability of the manipulator. , in addition, the existing portable manipulators and their end tools are mostly connected by screws, which also have the problems of long installation and disassembly, poor portability, and do not have a limit function. Axial deflection is prone to occur between the tool and the end tool, which affects the normal use of the robotic arm. At the same time, the structural strength is low, it is easy to be deformed and broken by external force, the work reliability is poor, and the connection is not firm, which cannot meet the needs of high-intensity scenarios.
