It is scheduled on base upper surface.
Further, upper and lower two shaft shoulders are equipped between the axle sleeve and plane bearing, are equipped between the upper shaft shoulder and axle sleeve
Cylindrical spring, the lower shaft shoulder connect with the upper surface of plane bearing.
The beneficial effects of the utility model：The utility model drives jackshaft to rotate by Worm Wheel System, jackshaft
The driven wheel of differential of two Intermediate bevel gears difference engaged transmission respective end at both ends, so as to which leading screw be driven to be formed with screw thread column sleeve
Screw mechanism rotate, since the leading screw of two screw mechanisms is oppositely oriented, the meshing characteristic of combination gear so that motor rotate
When two screw thread column sleeves move up and make erecting bed along guide-rail plate elevating movement, so as to fulfill being moved down on index dial
It is dynamic, to change the clamping axis height of scroll chuck, the clamping of different bent axles is adapted to, for the offset or dish model up and down of connecting rod neck
Larger bent axle is enclosed also to avoid using jumping chisel by its clamping in top or lower position, to adapt to the bit run of drilling machine
Head collapses brill, while carries indexing function, the setting angle of bent axle can be directly adjusted, to process the hole on respective link neck.
