Mechanical arm convenient to adjust

Abstract

The invention discloses a mechanical arm convenient to adjust. The mechanical arm comprises a hollow mounting block with an opening in the bottom, wherein a rectangular rod is vertically welded to theinner walls of the opposite sides of the opening; a driving motor is fixed to one side of the hollow mounting block through screws; a first threaded rod rotationally connected with the hollow mounting block is fixed to an output shaft of the driving motor through a shaft coupler; the first threaded rod is positioned on the inner side of the hollow mounting block; forward and reverse threads are formed in the outer side of the first threaded rod in the length direction; a group of slide blocks in threaded connection with the forward and reverse threads respectively are in threaded connection with the outer side of the first threaded rod in a sleeving manner. Through a knob, connecting sleeves, a second threaded rod, a guiding rod, first limiting plates, second limiting plates and telescopic rods, the distance between a second clamping head and a first clamping head can be adjusted as required, and then the distance between contact points when an object is clamped is changed, so that the mechanical arm convenient to adjust is strong in adjustability, thereby being capable of clamping objects with different heights and good in universality.

Description

Technical field [0001] The invention relates to the technical field of manipulators, in particular to a manipulator that is easy to adjust. Background technique [0002] The manipulator can imitate certain motion functions of human hands and arms, and is used as an automatic operating device for grasping, transporting objects or operating tools according to a fixed program. Manipulators are the earliest industrial robots and the earliest modern robots. They can replace human labor to achieve mechanization and automation of production, and can operate in harmful environments to protect personal safety. Therefore, they are widely used in machinery manufacturing, metallurgy, Departments of electronics, light industry and atomic energy. [0003] However, the mechanical claws of the existing manipulators can only be used for grasping objects of specific specifications because the length of the mechanical claws is fixed when clamping objects. For some taller and longer objects, it is no...

Problems solved by technology

[0003] However, when the mechanical claws of the existing manipulators are clamping objects, because the length of the mechanical claws is fixed, it can only be used for grabbing objects of specific specifications. For some taller and longer objects, it is not suitable. It is easy to hold, but it is easy to fall off. For this reason, an easy-to-adjust manipulator is needed to solve the above problems, so that it can be applied to a wider range and have better general performance. For this reason, in-depth research is needed.
