Description

technical field [0001] The invention relates to numerical control processing equipment, and further refers to a gear milling machine and a gear grinding machine for processing spiral bevel gears. Background technique [0002] In the prior art, spiral bevel gear processing equipment includes mechanical spiral bevel gear processing machine tools and numerically controlled spiral bevel gear processing machine tools. 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, the spiral bevel gear processing machine tool adopts the structure shown in Figure 1, which uses a computer to directly control three linear axes (ie X, Y, Z axes) and three rotational axes (ie A, B, C axes) , that is, the machining motion of the mechanical spiral bevel gear processing machine can be simulated, so as to process the spiral bevel gear. The CNC spiral bevel gear processing m...

AI Technical Summary

Problems solved by technology

This treatment does not give full play to the role of numerical control technology, and there are the following main defects:

[0003] 1. There is a sector gear or friction wheel with a large diameter on the Z-axis sliding table 22 in the Z direction of the linear axis, and the processing technology is not good;

[0004] 2. The shape of the workpiece box 28 is complicated, the manufacturability of the processing is not good, and it is difficult to ensure the processing accuracy;

[0005] 3. All the weight of the workpiece box 28 is pressed on the sector gear or the friction wheel, so it is difficult to unload;

[0006] 4. The X-axis sliding table 25 in the X direction of the linear axis is a gantry, and the Y-axis sliding table 24 in the Y direction of the linear axis moves vertically on the gantry. 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, the device in Figure 1 is difficult to do this;

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

[0009] The patent application publication with publication number CN1457279 records a machine for producing bevel gears. This machine sets the tool spindle and the workpiece spindle on a column, and its structure not only leads to high manufacturing costs, but also poor assembly manufacturability
