Grinding wheel finishing device for helical bevel gear grinding machine

Abstract

The invention discloses a grinding wheel finishing device for a helical bevel gear grinding machine, comprising a workpiece box (2). A grinding wheel finishing head (1) is installed on a linear lead rail (7) in a sliding mode and installed on the workpiece box (2) through the linear lead rail (7); the moving direction of the grinding wheel finishing head (1) is vertical to the axes of a workpiece box spindle (3) arranged on the workpiece box (2); the grinding wheel finishing head (1) is driven by a hydraulic cylinder (10); and the bottom of the workpiece box (2) is installed on a rotary table (9). The grinding wheel finishing device for the helical bevel gear grinding machine has simple structure, high rigidity, more stable finishing precision and high finishing efficiency.

Description

technical field [0001] The invention relates to a grinding wheel dressing device, in particular to a grinding wheel dressing device for a spiral bevel gear grinding machine. Background technique [0002] The existing grinding wheel dressing device for spiral bevel gear grinding machine has insufficient rigidity when dressing the grinding wheel, and the surface precision of the dressed grinding wheel is unstable, which directly leads to unstable performance of the machine tool during grinding and obvious ripples on the surface of the workpiece. [0003] The current structure of the dressing device of the spiral bevel gear grinding machine, such as figure 1 and figure 2 : The grinding wheel dressing device is installed above the workpiece box 2 and parallel to the workpiece box spindle 3. When the grinding wheel is being dressed, the grinding wheel dressing head 1 is pushed to the upper limit position on the linear guide rail 5 through the cylinder 4, and is pushed to the up...

AI Technical Summary

Problems solved by technology

[0010] The grinding wheel dressing device for the spiral bevel gear grinding machine adopts the above scheme, the installation position of the grinding wheel dressing head is changed from parallel to the main shaft of the workpiece box to be vertical, and the B axis of the turntable connected with the workpiece box is rotated 90o to make the grinding wheel dressing head and the grinding wheel Facing, enter the trimming position, and trim the grinding wheel profile through the X-axis (vertical) and Z-axis (horizontal) linkage interpolation method of the machine tool, completely avoiding the position limitation of the original structure to avoid the processing area. Grinding wheel dressing The head is laterally displaced to the left limit position through the hydraulic cylinder, and the cantilever is shortened because it does not need to avoid the position occupied by the workpiece, which improves the rigidity and solves the problems of poor positioning and unstable positioning caused by complex structures; hydraulic drive is adopted, The problem of insufficient locking pressure after the dressing head is in place is improved, and the rigidity of the dressing head is improved during dressing
