Abstract

The utility model discloses a coarse grinding and accurate grinding automatic switching mechanism of a vertical spindle rotary table surface grinder, which comprises an upright post and a wheel head body. A wheel head planker is arranged between the upright post and the wheel head body, one side of the wheel head planker is fixed on the upright post, and an automatic tripping and locking device, a drive rotating clearing device, and a hinge assembly are arranged between the other end of the wheel head planker and the wheel head body. The automatic switching mechanism has the beneficial effects that the wheel head planker is arranged between the upright post and the wheel head body, the wheel head body can be automatically tripped and rotated for a certain inclination angle on the wheel head planker and then be pressed to achieve the coarse grinding and accurate grinding automatic switching, so the shortcoming of the prior art is avoided. The technical problems that the structure compact difficulty is too big and the pressing state can be achieved after being rotated when a few tons of pressing force of the wheel head is instantly tripped and rotated for a certain angle and then compressed and a few tons of pressing force is tripped instantly by hundreds of kilograms oil pressure to complete, and the reliability is ensured under the state of large cutting output of the vertical spindle rotary table surface grinder, and the technical problem that the coarse grinding and accurate grinding automatic switching is very convenient is solved.

Description

Coarse and precise grinding automatic switching mechanism for vertical shaft rotary surface grinder

Technical field

The utility model relates to vertical surface grinding machine with round table, particularly be coarse and precise grinding automatic switching mechanism for vertical shaft rotary surface grinder.

Background technology

As shown in Figure 1, is connected by adjusting screw 5 between the column 1 of the vertical surface grinding machine with round table of prior art and the lathe bed 12, grinding head body 3 and fixing in its lower section grinding wheel chuck 4 and column 1 are fixed as one.Large-scale workpiece once is installed on above-mentioned vertical surface grinding machine with round table and finishes thick, correct grinding processing, the adjustment screw 5 of column 1 with lathe bed 12 lockings must be unclamped, after column being transferred oblique drive grinding head body 3, grinding wheel chuck 4 inclination certain angles again, screw 5 is adjusted in locking again, roughly grinds processing; After corase grind machines, unclamp and adjust screw 5, adjust column 1 and reset, column 1 drives grinding head body 3, grinding wheel chuck 4 makes its center line recover the vertical table face, and lathe finish grindes after reaching the correct grinding state.

Above-mentioned prior art wants once to be installed and finishes slightly, finish grindes processing, do not unloading under the workpiece prerequisite, needing repeatedly to unclamp repeatedly, lock to adjust screw 5, just can reach the correct grinding perfect condition, adjustment process exists that efficient is low, difficulty is big, reaches time-consuming, the effort of correct grinding perfect condition.If when next workpiece is roughly ground, be at lathe under the situation of correct grinding state, finish at the bottom of the corase grind efficient utmost point, can not bring into play the lathe effect.For overcoming above-mentioned the deficiencies in the prior art, the existing most of elder generations of user are adjusted into the corase grind state with lathe, and behind a collection of workpiece of corase grind, adjusting lathe again is the correct grinding state, finishes the correct grinding of a collection of workpiece earlier.When lathe is adjusted the correct grinding state,, lathe must be adjusted into the corase grind state if want to roughly grind part.The at present domestic scheme that does not also have proposition to solve the problems of the technologies described above.

Summary of the invention

The purpose of this utility model is to overcome the deficiency of above-mentioned technology, provide a kind of with grinding head body and fixing in its lower section grinding wheel chuck and column between be provided with and have and can change automatically, the convenient coarse and precise grinding automatic switching mechanism for vertical shaft rotary surface grinder of adjusting.

The technical scheme that solves the problems of the technologies described above is: a kind of coarse and precise grinding automatic switching mechanism for vertical shaft rotary surface grinder, described coarse and precise grinding automatic switching mechanism for vertical shaft rotary surface grinder comprises: column, grinding head body, between described column and grinding head body, be provided with the bistrique planker, described bistrique planker one side is fixed on the column, is provided with the rotating restoring device and the articulated mounting that unclamp locking device, hydraulic control system driving automatically of spring clip locking oil cylinder between bistrique planker opposite side and the grinding head body.

The beneficial effects of the utility model are: the utility model is to be provided with the bistrique planker between column and grinding head body, grinding head body can be unclamped the certain angle of inclination of rotation automatically and be compressed and reach thick, correct grinding conversion automatically on the bistrique planker, the defective of avoiding prior art repeatedly to unclamp repeatedly, lock adjusting screw adjustment column and grinding head body to bring.The utility model has solved several tons of thrusts of bistrique moments and has unclamped to rotate to an angle and compress, several tons of thrust moments unclamp and need hundreds of kilogram oil pressure to finish, the compact conformation difficulty is too big, reach impaction state after the rotation again, and can guarantee that vertical surface grinding machine with round table roughly grinds the reliability under the big cutting output state, solve that industry neutral axis rotary grinder is thick, the correct grinding technical barrier of conversion automatically very easily.
