Six-shaft and five-linked machine tool for spiral conical gears

Abstract

A six-axle five-leakage machine-tool for machining spiral bevel gear is composed of a main body, X-axis straight guide track on said main body, X-axis slide table on said X-axis track, Y-axis straight guide track on said X-axis slide table, a slide vertical post on said Y-axis track, a Z-axis guide track on one lateral surface of said vertical post, a cutting tool box moving on said Z-axis track, a C axle on said cutting tool box for installing cutter head or abrasive disc, a B axle for driving cutting tool box to rotate, and an A axle on said cutting tool box for installing the spiral bevel gear to be machined.

Description

technical field [0001] The invention relates to numerical control processing equipment, and further refers to a numerical control spiral bevel gear milling machine and a gear grinding machine. Background technique [0002] In the prior art, the structure and adjustment links of mechanical spiral bevel gear processing machine tools are the most complicated among gear machine tools. With the advancement of technology, spiral bevel gear processing machine tools have adopted figure 1 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 spiral bevel gear. The CNC spiral bevel gear processing machine tool converts the complex mechanical structure into software control, realizing the informatization and intelligence of spiral bevel gear processing.

Problems solved by technology

However, the above-mentioned equipment is a kind of intentionally simulating the structure of a mechanical machine tool. The rotation mechanism of the cradle is changed to the linkage of X and Y axes to realize the rotation of the tool around the axis of the cradle, and the function of the tool tilt mechanism is changed to the swing of the B axis. The role of numerical control technology is not fully utilized, so there are still the following defects:

[0003] 1. There is a sector gear or friction wheel with a large diameter on the Z-axis sliding table 1 in the Z direction of the linear axis, and the processing technology is not good;

[0004] 2. The shape of the workpiece box 4 is complicated, the manufacturability of the processing is not good, and it is difficult to guarantee the processing accuracy;

[0005] 3. All the weight of the workpiece box 4 is pressed on the sector gear or friction wheel, so it is difficult to unload;

[0006] 4. The X-axis sliding table 2 in the X direction of the linear axis is a gantry frame, and the Y-axis sliding table 3 in the Y direction of the linear axis moves vertically on the gantry frame. The servo motor and hydraulic balance cylinder are erected very high, and the protection is very difficult;

[0007] 5. For the sake of environmental protection and saving, the development direction of spiral bevel gear milling is dry cutting, that is, no coolant is added during processing, the cutting speed is very fast, and the heat is taken away by chips, which requires that hot chips cannot fall on the bed. , so as not to affect the thermal deformation of the machine tool, figure 1 It is difficult for the device to do this;

[0008] 6. The machine tool occupies a large area, and it is inconvenient to load and unload the workpiece
