Universal grinding carriage for internal gears and external gears of formed grinding wheel gear grinding machine

Abstract

The invention provides a universal grinding carriage for internal gears and external gears of a formed grinding wheel gear grinding machine, comprising a horizontal cantilever; the lower end surface of the horizontal cantilever is connected and fixed with a vertical grinding arm by a bolt; and the side surface of the lower end of the vertical grinding arm is fixed with a grinding head component. The grinding carriage is directly arranged on the formed grinding wheel gear grinding machine and not only can process external gears, but also can process internal gears; when the external gears are ground, the whole grinding carriage is rotated by 180 degrees only, and the grinding carriage has good rigidity; when helical gears are ground, a grinding wheel can not generate interference with workpieces; the grinding wheel has convenient repair and maintenance, low cost and high cost performance.

Description

technical field [0001] The invention relates to a universal grinding wheel frame for internal and external gears of a forming grinding wheel gear grinding machine. Background technique [0002] Existing large-scale forming grinding wheel gear grinding machines have a single processing type, internal tooth forming grinding wheel gear grinding machines can only process internal gears, and external tooth forming grinding wheel gear grinding machines generally only process external gears. If the external tooth forming grinding wheel gear grinding machine needs to process internal gears, the first solution is to remove the existing external tooth forming grinding wheel gear grinding machine grinding wheel frame and add a set of special internal tooth forming grinding wheel gear grinding machine grinding wheel frame, resulting in The cost increases and the assembly difficulty increases. The second solution is to add a set of internal tooth forming grinding wheel gear grinding mac...

Problems solved by technology

[0002] The existing large-scale forming grinding wheel gear grinding machine has a single processing type, the internal tooth forming grinding wheel gear grinding machine can only process internal gears, and the external tooth forming grinding wheel gear grinding machine generally only processes external gears

If the external tooth forming grinding wheel gear grinding machine needs to process internal gears, the first solution is to remove the existing external tooth forming grinding wheel gear grinding machine grinding wheel frame and add a set of special internal tooth forming grinding wheel gear grinding machine grinding wheel frame, resulting in Increased cost and increased difficulty in assembly

The second solution is to add a set of internal tooth forming grinding wheel gear grinding machine grinding wheel arm on the frame of the external tooth forming grinding wheel gear grinding machine, which not only increases the cost, but also increases the difficulty of assembly. More importantly, this structure causes the internal gear The rigidity of the grinding wheel arm is poor, and when the grinding wheel is trimmed, it needs to rotate an angle to solve the dressing problem, and the positioning accuracy of the rotation is not easy to guarantee; in addition, there is also the problem of interference, because the entire grinding wheel arm has to rotate when grinding helical gears, if the helix angle is too large, Grinding wheel and workpiece may interfere

Therefore, both of the above two solutions affect the machining accuracy and assembly process of the entire machine tool.
