Embodiment Construction
[0029] The present invention will be described in detail below in conjunction with the accompanying drawings, as shown in the figure: the gear grinding machine that can be used for precision machining half-cutting and shaper cutters in this embodiment includes a grinding machine body 1, an indexing device 2, a grinding wheel lifting carriage 3, and a grinding wheel 4. The grinding wheel lifting adjustment device 5, the grinding wheel longitudinal adjustment device 6, the grinding wheel horizontal adjustment device 7 and the grinding wheel main edge dresser 8. This embodiment adds a tooling that can precisely process the half-cutting and shaper cutter on the basis of the Y7125 gear grinder. In the Y7125 On the gear grinder, the horizontal direction refers to the direction of the output shaft of the indexing device, that is, if figure 1 The left and right directions in the view, the longitudinal direction refers to the direction perpendicular to the horizontal plane in the horizo...

The invention discloses a gear grinding machine capable of precisely machining a semi-topping slotting cutter. The gear grinding machine comprises a grinding machine body, a dividing device, a grinding wheel lifting carriage, a grinding wheel, a grinding wheel lifting adjusting device, a longitudinal grinding wheel adjusting device, a transverse grinding wheel adjusting device, a grinding wheel major cutting edge trimmer, a grinding wheel semi-topping trimmer and a grinding wheel lifting displacement measuring device. The semi-topping trimmer and the displacement measuring tool are designed by utilizing the principle of a Y7125 gear grinding machine, the implementation cost is low, an angle between a chamfering diamond pen of the grinding wheel semi-topping trimmer and a side face of the grinding wheel and the feeding amount of the chamfering diamond pen of the grinding wheel semi-topping trimmer in the radial direction of the grinding wheel can be adjusted according to the data; because an involute profile of the major cutting edge and the semi-topping involute profile are ground by two trimmers, the tooth profile intersection is clear, the time of adjusting the angle can be effectively shortened, and the production efficiency is improved; and meanwhile, the grinding precision of the semi-topping slotting cutter can be effectively guaranteed, and the gear grinding machine has good popularization and application prospect.
Description
technical field [0001] The invention relates to the technical field of machine tools, in particular to a gear grinding machine capable of accurately adjusting the grinding angle of a half-cutting top and the position compensation adjustment of a grinding wheel during the grinding process according to data. Background technique [0002] The gear that cuts off one more piece on both sides of the tooth angle of the gear (that is, the chamfering of the tooth tip) is commonly called a trimmed gear, and it is also called a half-truncated gear according to the processing method of the gear tooth. Half truncated gears are beneficial to reduce the impact caused by various errors, and have been widely used in the gear transmission of automobiles, motorcycles, transmission machinery and other products. At the same time, the requirements for machining accuracy are getting higher and higher. [0003] To process high-precision half-cutting gears, the accuracy of the half-cutting gear shap...
