Manipulator

Abstract

The invention provides a manipulator, belonging to the technical field of machinery and aiming at solving the problem of poor sealing effect in the present manipulator. The manipulator comprises a main body and a flange plate fixedly connected to the circumference of the main body; the flange plate is fixedly connected with an end cover by means of screws; the main body comprises a cylindrical connecting end; a clearance is formed between the flange plate and the end surface of the connecting end of the main body; the heads of the screws are located inside the clearance; a plurality of through holes distributed along the circumference are arranged on the end surface of the flange plate; the through holes comprises demising holes for the penetration of the heads of the screws and limiting holes capable of preventing the penetration of the heads of the screws; the limiting holes and the demising holes are communicated; a cylindrical support drum capable of moving along the axial direction of the flange plate is arranged in the clearance; an annular shoulder is formed on the external side wall of the end part of the support drum adjacent to the flange plate and is propped against the flange plate; a rubber ring sleeves the external side wall of the support drum; two end surfaces of the rubber ring are respectively propped against the annular shoulder and the end surface of the connecting end. And the manipulator has good sealing effect.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to a mechanical arm. Background technique [0002] The robotic arm is currently the most widely used automated mechanical device in the field of robotics. It can be seen in industrial manufacturing, medical treatment, entertainment services, military, semiconductor manufacturing, and space exploration. Although their shapes are different, they all have a common feature, that is, they can accept instructions and precisely locate a certain point in three-dimensional (or two-dimensional) space for operation. [0003] In the prior art, the joints on the mechanical arm or the connections between the joints and the end caps or between the joints and other components are directly connected by fasteners such as screws, so that the screws are directly exposed on the mechanical arm. When the mechanical arm is used under relatively harsh working conditions, impurities such as dust and water ca...

AI Technical Summary

Problems solved by technology

When the mechanical arm is used under relatively harsh working conditions, impurities such as dust and water can easily enter the mechanical arm through the screw connection, affecting the normal operation of the mechanical arm

At the same time, since there are many joints on the mechanical arm, and there are many positions that need to be connected, the number of screws used is also large, so that more impurities such as dust and water enter the mechanical arm through the joints of the screws, greatly Affect the normal work of the robotic arm
