Further, the external lower bistrique in axle upper end is covered.
Lock shaft handle controls cam, and then drives axle sleeve and lock shaft roller bearing, lock shaft roller bearing connection wedge block lower end, drives
Wedge block move up and down, when need lower bistrique is finely adjusted when, using lock shaft handle control wedge block move downward, set axle with
Both standard shafts are changed into relaxed state from wedging state, and then adjust digital hand wheel, and digital hand wheel connection worm screw, worm screw drives worm gear
Rotate, the screw thread set on the inside of worm gear with set axle lower end matches, and worm gear rotates around standard shaft, and set axle slides axially along standard shaft just can
Realize the fine setting effect of lower bistrique upper-lower position.After fine setting terminates, only lock shaft handle need to be adjusted to lock gear, will set axle with
Standard shaft wedging just can lock lower bistrique.
The present invention the advantage is that relative to prior art：
1, the present invention adjusts the position of lower bistrique using digital hand wheel manually, it is assumed that sets the lead for covering axle and worm gear
It is set to 2mm, the number of teeth of worm gear is arranged to 50, and digital hand wheel scale is from being 40 lattice/circle, then a lattice are often rotated, on upper bistrique
It is 2mm/ (50*40)=1 μm that raise-position, which moves, i.e. trimming precision can reach 1 μm；It can be seen that the present invention can improve regulation
Precision；
2, the present invention using worm-and-wheel gear and cover screw pair that axle and worm gear form control upper bistrique above and below
Displacement, the lock-out state of upper bistrique is adjusted using cam mechanism, it is simple in construction, device manufacturing cost can be reduced.
