High-precision and heavy-load forking mechanism

Abstract

The high-precision heavy-duty fork picking mechanism disclosed by the present invention has compact structure, small space occupation, and good overall rigidity, which can provide a larger movement stroke for the workpiece, and realize high-precision, heavy-duty fork picking and transportation of the workpiece; when working, the servo The motor drives the gear to rotate, and the boom slides laterally along the lower guide rail under the drive of the gear and rack structure. Driven by the chain, the tray moves along the upper guide rail in the same direction at a speed twice the sliding speed of the boom, that is to say , when the boom moves a certain distance, the moving distance of the pallet and the workpiece is twice that of the boom, so that the workpiece can be forked conveniently and accurately and transported to its place; The post-maintenance is convenient and labor-saving, and the accuracy of the whole mechanism is effectively improved. In particular, the servo motor used has the characteristics of high positioning accuracy and can provide variable acceleration motion, which makes the transportation process of the mechanism smooth and smooth, and finally realizes the workpiece. precise positioning.

Description

technical field [0001] The invention relates to a forking mechanism, in particular to a high-precision heavy-duty forking mechanism applied to an automatic machine tool processing line in the field of numerical control machine tools. Background technique [0002] Now the domestic CNC machine tool processing generally adopts the working mode of single machine tool processing, but now the mechanical processing is becoming more and more complex, and the division of machine tools is becoming more and more clear. In many cases, a single workpiece needs to be processed by multiple machine tools. On this premise Under the circumstances, the problem of low efficiency in the transfer of workpieces between machine tools has become increasingly prominent; moreover, with the increasing labor costs today, the less-mannered and automated machine tool processing mode has gradually become the development direction of the industry.

Problems solved by technology

[0002] Now the domestic CNC machine tool processing generally adopts the working mode of single machine tool processing, but now the mechanical processing is becoming more and more complex, and the division of machine tools is becoming more and more clear. In many cases, a single workpiece needs to be processed by multiple machine tools. On this premise Under the current situation, the problem of low efficiency in the transfer of workpieces between machine tools has become increasingly prominent; moreover, with the increasing labor costs today, the less-mannered and automated machine tool processing mode has gradually become the development direction of the industry

However, domestic research on CNC machine tool assembly lines is still in its infancy.

[0003] At present, automatic machine tool processing lines in the field of CNC machine tools such as FMS (flexible manufacturing system) mostly adopt the stacker form commonly used in three-dimensional warehouses, but due to the particularity of the machine tool industry, the stacker structure used in three-dimensional warehouses cannot be directly applied. Especially for horizontal forking, the existing forking mechanism in the form of stacker has technical problems such as unreasonable structure, heavy weight, large space occupation, small load, low precision, inconvenient installation and adjustment, and difficult processing and manufacturing, etc., so it is not applicable In the special field of CNC machine tool processing
