Summary of the invention

For solving prior art Problems existing, the utility model proposes a kind of simple in construction, the fine setting locking device for grinding machine that precision is high。

This utility model is the technical scheme that solution prior art Problems existing adopts: for the fine setting locking device of grinding machine, including main shaft frame, standard shaft, sleeve, worm gear and worm screw；Standard shaft runs through main shaft frame, and sleeve is placed on standard shaft and can slide axially；The lower end of sleeve is provided with screw thread, and worm gear is placed on the inner circle of the lower end of sleeve, screw thread and worm gear and matches；Worm and wheel engages。

Further, being provided with wedge block between sleeve and standard shaft, wedge block is provided with grooved cam mechanism。

Further, grooved cam mechanism includes cam, camshaft, lock shaft roller bearing, axle sleeve, lock shaft handle；Lock shaft roller bearing couples with wedge block lower end, and lock shaft roller bearing is cased with axle sleeve, and axle sleeve mates with the groove of cam, and cam couples with lock shaft handle；Camshaft couples with cam rotation。

Further, worm gear is positioned in main shaft frame by worm gear pressure ring and worm gear packing ring, and worm screw is positioned in main shaft frame by two deep groove ball bearings, adjustment spacer, worm screw gland；Standard shaft lower end is provided with the tight ring of standard shaft, and standard shaft is coupled with the bottom surface of main shaft frame by the tight ring of standard shaft。

Further, axle sleeve is by clamping back-up ring location。

Further, worm screw one end is provided with the digital hand wheel containing scale；Uniform reticulate pattern on the face of cylinder of digital hand wheel。

Further, the external lower bistrique in sleeve upper end。

Lock shaft handle controls cam, and then drive axle sleeve and lock shaft roller bearing, lock shaft roller bearing couples wedge block lower end, drive wedge block moves up and down, when lower bistrique is finely tuned by needs, use lock shaft handle to control wedge block to move downward, sleeve and both standard shafts become relaxed state from wedging state, and then adjustment digital hand wheel, digital hand wheel couples worm screw, and worm screw drives worm gear wheel, and the screw thread arranged with sleeve lower end inside worm gear matches, worm gear rotates around standard shaft, and sleeve 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 locking gear, sleeve and standard shaft wedging just can be locked lower bistrique。

This utility model, relative to prior art, has an advantage in that:

1, this utility model uses the position of bistrique under digital hand wheel manual adjustments, assuming that the lead by sleeve Yu worm gear is arranged to 2mm, the number of teeth of worm gear is arranged to 50, it is 40 lattice/circle that digital hand wheel scale is selected, so often rotating lattice, upper bistrique rising displacement is 2mm/ (50*40)=1 μm, and namely trimming precision can reach 1 μm；This shows that this utility model can improve degree of regulation；

2, this utility model uses the screw pair that worm-and-wheel gear and sleeve and worm gear are constituted to control the upper and lower displacement of upper bistrique, uses cam mechanism to regulate the lock-out state of bistrique, simple in construction, it is possible to reduce device manufacturing cost。
