Abstract

The invention relates to a four-axis and four-linkage numerical control generating machine of arc bevel gear and belongs to the field of the gear generating machine technology. The invention comprises a machine body, a workpiece box and a cutting tool box. The machine body is fixedly provided with a straight guide rail of Z-axis and a straight guide rail of X-axis. The straight guide rail of X-axis drives a saddle to do the straight line motion via a servo motor. The saddle is provided with a workpiece box and rotates around a rotary shaft to do the rotary motion of B-axis for adjusting the required cone angle of gear root. The workpiece box is provided with a workpiece spindle which is driven by the servo motor to do the rotary motion of A-axis. The straight guide rail of Z-axis drives a vertical column to do the straight motion of Z-axis via the servo motor. The vertical column is fixedly provided with a straight guide rail of Y-axis which drives the cutting tool box to do the straight and reciprocating motion in the vertical direction of Y-axis via the servo motor. The main motor on the cutting tool box drives the cutting tool disk which is provided with the cutting tool to rotate for doing the rotary motion of C-axis of gear cutting. The four-axis and four-linkage numerical control generating machine of arc bevel gear has the advantages of simple structure, humanized layout, convenient loading and unloading of the workpiece, good dynamic rigidity and dynamic balancing, and small occupied area.

Description

technical field [0001] The invention belongs to the technical field of gear milling machines, and in particular relates to the layout of a four-axis four-linkage numerical control spiral bevel gear milling machine. Background technique [0002] At present, the structure and adjustment links of the mechanical type spiral bevel gear processing machine tools of the known technology are the most complicated among the gear machine tools. image 3 As shown in the structure, it uses a computer to directly control three linear axes (namely X, Y, Z axes) and three rotational axes (namely A, B, C axes), that is, it can simulate the machining motion of a mechanical spiral bevel gear processing machine tool , so as to process the helical gear. The layout of the machine tool is a deliberately simulated mechanical machine tool structure, which does not give full play to the technical characteristics and functions of the CNC machine tool. Therefore, there are technical problems such as poo...
