h type parallel robot

Abstract

The invention discloses an H-type parallel robot. The H-type parallel robot comprises a rack, a workbench, X-direction assemblies, a Y-direction assembly and a Z-direction assembly, wherein the two X-direction assemblies are symmetrically arranged on the left side and the right side of the workbench, each X-direction assembly comprises an X-direction guide rail and an X-direction slider assembly, the Y-direction assembly comprises a Y-direction guide rail and a Y-direction slider assembly, and the Z-direction assembly comprises an executing part and an air cylinder or an electric cylinder; a driving motor and a driving synchronous belt wheel are installed at the front end of each X-direction guide rail, a driven synchronous belt wheel is installed at the rear end of each X-direction guide rail, and the front side and the rear side of the joint between each X-direction slider assembly and the Y-direction guide rail are each provided with an idler wheel; an H-type frame composed of the X-direction assemblies and the Y-direction assembly is sleeved with an H-type synchronous belt, the driving synchronous belt wheels are driven by the driving motors to rotate, the driven synchronous belt wheels are driven by the driving synchronous belt wheels to rotate through the synchronous belt, and finally, the executing part is driven to move in the X direction and the Y direction. The H-type parallel robot is simple in structure, low in manufacturing cost, good in structural strength and high in position accuracy and is a real environment-friendly energy-saving robot.

Description

technical field [0001] The invention relates to the technical field of industrial robots. Background technique [0002] With the continuous improvement of industrial automation level, robots are widely used in various fields of industrial production. Robots are roughly divided into three categories: parallel robots, articulated robots, and serial robots. To achieve X-, Y-, and Z-direction movements, the actuators need to be driven by matching different powers. During the movement, the power of each axis or the weight of the motor itself will be superimposed on the moving load, resulting in power consumption. Moreover, the main structural problems of existing industrial robots are: the rigidity of the overall structure is not enough, the position accuracy of the execution part is difficult to control, the structure is complicated, and the manufacturing cost is high. Contents of the invention [0003] The present invention improves on the above technical problems, and inte...
