Abstract

The utility model relates to the field of medical equipment manufacturing, in particular to a high-precision numerical control internal grinder, which is provided with a grinder body. An X-shaft worktable is mounted on the grinder body; a Y-shaft worktable is mounted at one end of the X-shaft worktable provided with an X-shaft driving device; a grinding head is mounted on the Y-shaft worktable provided with a Y-shaft driving device; a tailstock is mounted at the other end of the X-shaft worktable; and concentric clamp heads are mounted on the tailstock. Particularly, a bottom plate is additionally mounted above the tailstock; the concentric clamp heads are fixedly mounted on the bottom plate; two rotary shafts are mounted at the centers of the front ends of the bottom plate and the tailstock to connect the bottom plate and the tailstock; a rotary nut is mounted at the tail end of the bottom plate; a precision lead screw is mounted in the manner of matching with the rotary nut; and a servo motor mounted on the tailstock is in driving connection with the precision lead screw. The high-precision numerical control internal grinder solves the problems of inconvenient operation, low efficiency and low angle precision of a common internal grinder for grinding tapered hole parts, and is particularly applicable to processing tapered hole parts.

Description

The high precision numerical control internal grinder

(1) technical field: the utility model relates to plant equipment and makes field, especially a kind of high precision numerical control internal grinder.

(2) background technology: the method for processing taper hole class part is that the half-angle of projection that adopts measurer (bevel protractor, sine gauge) to adjust workpiece or the rotation of grinding head main shaft repeatedly according to measurement data or cooperation contact-making surface size realizes on plain grinding machine internal at present.The problem that this method of operating exists is: it is big 1. to adjust operation easier, the specification requirement height; 2. waste time and energy, efficient is low; 3. it is low to process the taper hole angle precision.

(3) summary of the invention: the purpose of this utility model is exactly to solve the problems referred to above that plain grinding machine internal processing taper hole class part exists, and a kind of high precision numerical control internal grinder is provided.

Concrete scheme of the present utility model is: improve at plain grinding machine internal, it has lathe bed, the X-axis workbench is installed on the lathe bed, one end of X-axis workbench is equipped with the Y-axis workbench, is furnished with the X-axis drive unit, grinding head is installed on the Y-axis workbench is furnished with the Y-axis drive unit, the X-axis workbench other end is equipped with tailstock, concentric clamping head is housed on the tailstock, it is characterized in that: above tailstock, add a base plate, the clamping head is installed on the base plate with one heart, with the front end center of tailstock one rotating shaft is installed at base plate and is connected both, and tail end is equipped with rotating nut on base plate, is fitted with accurate screw mandrel with rotating nut, and the installation driven by servomotor connects accurate screw mandrel on tailstock.

Accurate, reliable for the anglec of rotation that improves base plate and concentric clamping head, reduce to process the influence that vibration brings, it is the circular arc head at center that the tail end of base plate described in the utility model is made with the rotating shaft, and the circular arc head of corresponding base plate is equipped with arc-shaped guide plate on tailstock.

Operation principle of the present utility model is: clamping workpiece is before carrying out taper hole processing on the concentric clamping head, start servomotor transmission precision screw mandrel and pass through rotating nut, the promotion base plate drives concentric clamping head and rotates to an angle, and makes workpiece design taper hole face parallel with the emery wheel working face of grinding head.Grinding begins, and can process high-precision taper hole part by the emery wheel feeding.

The utility model compact conformation, improvement cost is low, adopts servomotor, accurate screw mandrel, rotating nut, base plate and rotating shaft to form an angle feed arrangement, and is easy to operate, quick, accurate, production efficiency height, processing parts precision height.
