Automatic processing equipment for crown gear

The invention provides automatic processing equipment for a crown gear, which comprises a guide rail, a crown gear processing table, a rotary working surface, a gear worm indexing mechanism, an indexing motor, a reciprocating motion reversing mechanism, a high speed and low speed switching mechanism and a power source, wherein the guide rail is arranged on the surface of a milling machine table; the crown gear processing table is arranged on the guide rail; the rotary working surface is positioned under the crown gear processing table and is connected with the gear worm indexing mechanism; an output shaft of the indexing motor is connected with a worm and can drive the gear worm indexing mechanism to perform high-precision indexing; the reciprocating motion reversing mechanism is arranged on the crown gear processing table below the rotary working surface; the high speed and low speed switching mechanism is arranged on the crown gear processing table, and the position of the high speed and low speed switching mechanism is slightly lower than the reciprocating motion reversing mechanism; the power source is a three-position cylinder which is arranged at the lowest part of the processing table and is used for driving the reciprocating motion reversing mechanism and the high speed and low speed switching mechanism. The automatic processing equipment for the crown gear is reasonable in structural design, simple and easy to install and good in processing effect.
