Be provided with the glass revolving door between said top cover and the bottom.
The said dish top of going up is equipped with motor.
Compared with prior art, the present invention has following outstanding advantage and effect:
1, adopt eccentric draft link rotation, the step-by-step movement that drives index dial is rotated, thereby realizes the step-by-step movement transmission, has dwindled the volume of lathe greatly.
2, with original 91 chucks, reduce to 32 chucks, thereby reduced the difference between chuck; Improved the precision of machine, all chucks are fixed on the annulus, make chuck inconsistent phenomenon can not take place; The processing action of all stations is controlled by a cam, and the degree of depth of processing is controlled by locating piece.
3, reduce the number of cam and draft link, reduced fault rate, and through the reducing the number of of parts, thereby reduced the operation of equipment difficulty, improve the stability of equipment, maintenance difficulty is reduced greatly, practiced thrift the manufacturing cost of machine greatly.
