Screw lead angle transmission mechanism based on full-automatic numerical control screw grinder

The utility model relates to the field of lead angle transmission mechanisms of numerical control thread grinders, in particular to a lead angle transmission mechanism based on a full-automatic numerical control thread grinder. Comprising a rack and a grinding wheel driven by a motor, the device further comprises a worm and gear transmission mechanism and a shell capable of being driven by the worm and gear transmission mechanism to rotate. The worm and gear transmission mechanism is installed on the rack, the shell is rotatably installed on the rack, the motor and the grinding wheel are installed on the shell, and a rotating shaft of the shell is perpendicular to a rotating shaft of the grinding wheel. Through the design that the worm gear and the worm drive the machine frame to rotate, the design of a high-precision large arc is avoided, and the beneficial effects of being easy to machine and mature in technology are achieved. 本实用新型涉及数控螺纹磨床的螺纹升角传动机构领域，具体是涉及基于全自动数控螺纹磨床的螺纹升角传动机构。包括，机架，由电机驱动的砂轮；还包括，蜗轮蜗杆传动机构，可由
