Specifically, as shown in Figure 2 and Figure 6, feeding mechanism 10, First look testing agency are provided on the workbench
20, angle alignment mechanism and cutting agency 70, wherein the worm screw that the feeding mechanism 10 can be such that batch is put into is successively whole
Arrangement is waited and being taken to subsequent processing；And the First look testing agency 20 successively takes and waits the worm screw of feeding, to snail
The size of six square end 1-4 of bar and clutch cone tooth 1-3 are detected, and then, the worm screw for the size qualification being selected is mechanical
Hand 50 is taken, and is placed into the angle alignment mechanism and is carried out angle alignment, meanwhile, it is realized under the auxiliary of angle alignment mechanism
It detects worm screw clutch conical tooth shaft and realizes the detection to length of worm to size and outer diameter, and by length-measuring appliance 34；
Then, worm screw is taken and carries out accurate gear hobbing to accurate gear hobbing station (not shown) by manipulator 50, finally will be after accurate gear hobbing
Worm screw place baiting structure 70 realize blanking；The accurate gear hobbing station is arranged in the angle in one of the embodiments,
Near alignment mechanism, existing precision hobbing machine can be used, therefore details are not described herein.
Incorporated by reference to Fig. 3 and Fig. 4, the feeding mechanism 10 is used to that feeding will to be waited after the worm screw of batch successively proper alignment,
Specifically, the feeding mechanism 10 includes that charging conveying assembly and feeding wait component；Wherein, the charging conveying assembly is used
Component is waited in the worm screw being put into batches is transmitted to the feeding one by one；The feeding waits component to be used for, and worm screw is whole vertically
Neat arrangement.
