Problems solved by technology

In the process of high-precision tooth surface grinding, the grinding wheel often needs to be dressed once after grinding several strokes. The frequency of grinding wheel dressing is high. This grinding method increases the idle stroke of the machine tool and reduces the processing efficiency.
At the same time, the separate grinding wheel dressing mechanism is often installed on a certain part of the machine tool when it is in use. Due to the existence of installation errors, the grinding wheel dressing accuracy is not stable enough, which affects the grinding accuracy of the tooth surface

Abstract

The invention relates to a gear form-grinding mechanism. The mechanism comprises a box, a main motor, a grinding component, a rotating component, a grinding wheel dressing component and a cooling component. When a grinding wheel needs to be dressed, it is only needed to rotate the grinding wheel in the vertical plane by 180 degrees through the rotating component so as to avoid a cooling liquid nozzle. The vertical movement of a diamond wheel and the rotation of the grinding wheel are linked according to a certain rule, so that the section of a grinding wheel spindle is dressed. Grinding wheel dressing is convenient, the idle stroke of a machine tool is short, and machining efficiency is high. A bevel gear can be ground simply by driving a worm and gear mechanism through a servo motor and adjusting the angle of the grinding wheel. The box is provided with two different positions connected with the machine tool to be used for machining of an external gear or machining of an internal gear respectively. The mechanism is convenient to use and adjust and wide in process range.

Description

technical field [0001] The invention relates to the field of grinding mechanisms, in particular to a gear forming grinding mechanism. Background technique [0002] In the process of high-precision hard tooth surface gear processing, it is often necessary to grind the quenched tooth surface. The maturity of numerical control technology and grinding wheel section dressing technology makes form grinding the most efficient and most popular gear finishing technology at present. The form grinding machine tool is the necessary special equipment, and the grinding head is the core component of the equipment. [0003] Traditional gear grinding heads can either only grind internal gears or only grind external gears. If one equipment is to grind internal and external gears at the same time, two grinding head mechanisms need to be designed and manufactured separately. And most of the existing grinding head mechanisms can only grind spur gears, but cannot grind helical gears, and th...
