Description

Modularized robot mechanical arm capable of being spliced rapidly Technical Field The utility model belongs to the technical field of mechanical arms, and particularly relates to a modularized robot mechanical arm capable of being spliced rapidly. Background The mechanical arm is a complex system with high precision, multiple inputs and multiple outputs, high nonlinearity and strong coupling, has been widely applied in the fields of industrial assembly, safety explosion prevention and the like due to the unique operation flexibility, and is a complex system with uncertainty of parameter perturbation, external interference, unmodeled dynamics and the like, so that the modeling model of the mechanical arm also has uncertainty, and the motion trail of the joint space of the mechanical arm needs to be planned for different tasks. At present, when carrying out the concatenation equipment to arm and base, adopt flange bolt to carry out fixed connection more, this just leads to need twisting a plurality of bolts and fix when assembling the combination, and the operation is comparatively loaded down with trivial details to influence installation and dismantlement efficiency. Disclosure of utility model In order to overcome the defects, the utility model provides the modularized robot mechanical arm for rapid splicing, which solves the problems that a plurality of bolts need to be screwed for fixing during splicing and combination and the operation is complicated, so that the installation and disassembly efficiency is affected. In order to achieve the aim, the utility model provides the technical scheme that the modularized robot mechanical arm comprises a base and a protective cover, wherein a square groove is formed in the base, a mechanical arm module is inserted and installed on the base, a fixed plate is connected in the base, grooves are formed in the inner walls of two sides of the base, an electric push rod is fixedly installed below the base, and a movable end of the electric push rod is connected with a movable plate; Guide slots are formed in two sides of the moving plate, the moving plate is connected with a hook plate through the guide slots in a sliding mode, a fixed block is connected to the mechanical arm module, a splicing column is connected to the lower portion of the mechanical arm module, limiting slots are formed in two sides of the splicing column, clamping slots are formed in the walls of the limiting slots, a plurality of positioning rods are connected to the shield, and fastening bolts are connected to the shield in a threaded mode. As a further scheme of the utility model, a plurality of positioning holes are formed in the fixed block, threaded holes are formed in the upper part and the lower part of the fixed block, the positioning rod is inserted into the positioning holes, and the fastening bolt is in threaded fit with the threaded holes. According to the utility model, the two sides of the base are connected with the limiting blocks, the sliding grooves are formed below the base, the connection part of the movable end of the electric push rod and the moving plate slides in the sliding grooves, and the moving plate slides in the square grooves, and the limiting blocks are in sliding fit with the limiting grooves.
