Description

CNC spiral bevel gear milling machine layout

technical field

The utility model belongs to gear processing machinery, in particular to a layout of a digitally controlled spiral bevel gear milling machine with simple structure, which can improve transmission efficiency and transmission precision and is suitable for processing gears of different tooth systems.

Background technique

Currently known CNC spiral bevel gear milling machines are composed of a bed, a cradle, a cradle support, a feed mechanism, and a workpiece box. The tool tilt structure, the mechanism of the above-mentioned machine tool is complex, a machine tool is composed of thousands of parts, and there are many transmission mechanisms installed at the same time, so the operation of the whole machine during assembly and debugging is more cumbersome. It also increases, resulting in a reduction in transmission accuracy, and its gear cutting accuracy is between 6.5 and 6 levels of the current national standard; when the gear milling machine needs to cut gears with different parameters, it is necessary to adjust the rotation angle of the machine tool such as the hanging wheel and the workpiece box, Horizontal wheel positions and vertical wheel positions, etc., thereby increasing trouble and labor intensity for operators, and time-consuming, laborious, and high production and processing costs.

In order to solve the technical problems in the known technology, the utility model provides a CNC spiral bevel gear milling machine layout with simple structure, which can improve transmission efficiency and transmission precision and is suitable for processing gears of different tooth systems.

The technical scheme that the utility model takes for solving the technical problem existing in the known technology is:

The CNC spiral bevel gear milling machine mainly includes a bed, a bed saddle, a workpiece box and a tool box. The X-axis guide rail is fixed on the bed, and the column is slidingly connected with the bed through the X-axis guide rail, and is fixed on one side of the column. There is a Y-axis guide rail, the tool box is slidingly connected with the column through the Y-axis guide rail, the tool spindle is installed in the tool box, the bed saddle is slidingly connected with the bed through the Z-axis guide rail fixed on the bed, and the workpiece box is fixed on the bed The arc plate on the saddle is slidingly connected with the saddle, and the workpiece spindle is set in the workpiece box.

The advantages and positive effects of the utility model are: the gear milling machine adopts the above-mentioned new layout, that is, the two linear axes of X and Y are used to replace the cradle part, and the linkage of X and Y axes plus B axis is used to replace the tool tilt. structure, and each moving part of the gear milling machine is controlled by numerical control, which effectively reduces the part types and transmission mechanisms of the current gear milling machine. The gear milling machine is not equipped with hanging wheels, which saves production costs, reduces adjustment time, and reduces The labor intensity of the operator is reduced. Due to the simplification of the transmission mechanism, the lubricating points of the machine tool are relatively reduced. The transmission of the transmission shaft is simple, which can improve the transmission efficiency and transmission accuracy. Through the movement of the above-mentioned axes and the change of the control program on the table gear milling machine, two kinds of gears with different tooth systems, the spiral bevel gear and the extended epicycloid gear, can be cut.
