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

Abstract

The invention discloses a high-precision and heavy-load forking mechanism. The high-precision and heavy-load forking mechanism is compact in structure, small in occupied space, good in overall rigidity and capable of providing a long movement stroke for a workpiece to achieve high-precision and heavy-load forking and transporting on the workpiece. During work, a servo motor drives a gear to rotate, a movable arm slides in the transverse direction of lower guide rails under the drive of a gear and rack structure, a tray moves in the same direction of upper guide rails under the drive of a chain at a speed two times of the sliding speed of the movable arm, in other words, after the movable arm moves by a certain distance, the moving distance between the tray and the workpiece is two times that of the movable arm, and therefore the workpiece can be conveniently and accurately forked and conveyed in place. According to the forking mechanism, two levels of transmission mechanisms are used for transmission, convenience and labor saving are achieved in later-period maintenance, in addition, the precision of the whole mechanism is effectively improved, especially the servo motor in use has the properties of being high in positioning precision and capable of providing variable accelerated movements so that the conveying process of the mechanism can be stable and smooth, and finally the workpiece is accurately positioned.

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. But domestic research on CNC machine tool assembly line is s...
