Abstract
The utility model relates to a sawtooth sliding type automatic telescopic honing head, and belongs to a honing head. A sawtooth mandrel is positioned in an outer sleeve of the honing head; a limit screw is fixedly connected with the sawtooth mandrel; the limit screw is in sliding connection with a groove on the outer sleeve of the honing head; springs are sleeved on the sawtooth mandrel; base plate working faces are arranged in elongated slots at the front end of the outer sleeve of the honing head, have sawtooth structures, and are supported by three tapered bevels; and sawteeth on the base plate working faces are meshed with sawteeth on the sawtooth mandrel. The utility model has the advantages that: the sawtooth sliding type automatic telescopic honing head has a novel structure and grinds for a long time, and the working faces cannot generate drum shapes; and when a feed mechanism of a machine tool returns to a position, the mandrel quickly pulls the base plate working faces back to the original state under the acting force of the springs, and inner holes of workpieces cannot be scratched or damaged.
Description
Technical field
The utility model belongs to a kind of honing head, is mainly used in aviation, space flight, the accurate holes processing of war products.
Background technology
Along with the develop rapidly of science and technology, engineering goods become increasingly complex, and precision is also increasingly high, and honing technique has obtained using widely in machinery manufacturing industry.
At present, the honing head that uses both at home and abroad is roughly the same, and its structure is by honing head, base plate (honing stone frame) working face (honing stone bar), tapering core bar, limited screw, and rubber ring or extension spring etc. are partly formed.The tapering core bar is installed in the honing head main aperture, and the base plate working face is installed in the honing head groove, and two place's grooves are arranged on the working face, and rubber ring or extension spring are enclosed within the groove, and the base plate two ends have two place's gradient faces to match with core bar two place's tapering faces, and play a supporting role.During the honing workpiece, under the control of machine tool feeding mechanism, the tapering core bar promotes the base plate inclined-plane and makes working face expansion grinding work piece; After feeding disappears, tapering core bar return, and the base plate working face leans on rubber ring or extension spring to shrink; Sensitivity is relatively poor; When unloading workpiece, inner hole wall is marked vestige by the oilstone bar or pulls, and influences the part serviceability.In addition, during feeding, tapering mandrel two place's tapering faces contact stressed with base plate two place's gradient faces; Stress point is at base plate working face two ends; The base plate middle part produces depressed deformation, and after honing a period of time, the wearing and tearing of working face (honing stone bar) both sides are big; The centre produces cydariform gradually, reduces base plate working face service life.
Summary of the invention
The utility model provides a kind of sawtooth slidingtype flexible automatically honing head, with solve the base plate working face workpiece endoporus is caused cut or pull, the base plate working face uses the problem that produces drum shape behind the certain hour.
The technical scheme that the utility model is taked is: the sawtooth core bar is positioned at the honing head overcoat; Stop screw is fixedly connected with the sawtooth core bar; The groove that this stop screw and honing head put outward is slidingly connected, and spring housing is connected on the sawtooth core bar, and the base plate working face is installed in the honing head overcoat front end elongated slot; This base plate working face adopts zigzag structure and adopts tapering inclined-plane, three places to support the sawtooth on this base plate working face and the engagement of this sawtooth core bar.
The utility model has the advantages that: the flexible automatically honing head core bar of novel structure, sawtooth slidingtype, base plate working face all adopt zigzag structure, and adopt tapering inclined-plane, three places to support; During the honing workpiece, under the effect of machine tool feeding mechanism, the sawtooth core bar is pushed ahead; Tapering inclined-plane, three places is evenly stressed, makes base plate working face expansion grinding work piece, owing to adopt three place's supporting surfaces; Long-time grinding, working face can not produce drum shape.During the machine tool feeding mechanism return, core bar retracts reset condition with the base plate working face fast under the active force of spring, can not cause cut or pull phenomenon the workpiece endoporus.
Description of drawings
Fig. 1 is the utility model structural representation, is machine tool feed when returning, and the sawtooth core bar retracts reset condition figure with the base plate working face under the effect of spring;
When Fig. 2 was the utility model honing, the sawtooth core bar was pushed ahead, base plate working face swelling state figure;
Fig. 3 is the utility model scheme of installation: zigzag base plate working face is installed in the outer grooving of honing head; Temporarily fix with leather sheath or rubber ring; Advance the sawtooth core bar gradually, under leather sheath or rubber ring elastic reaction, groove and toe joint touch; Unclamp core bar then gently groove and tooth are coincide, remove rubber ring or leather sheath again;
Fig. 4 is the utility model monnolithic case sketch map;
Fig. 5 is the whole cutaway view of the utility model.
The specific embodiment
Sawtooth core bar 2 is positioned at honing head overcoat 1; Stop screw 3 is fixedly connected with sawtooth core bar 2; The groove that this stop screw and honing head put outward is slidingly connected, and spring 4 is socketed on the sawtooth core bar, and base plate working face 5 is installed in the honing head overcoat front end elongated slot; This base plate working face 5 adopts zigzag structure and adopts tapering inclined-plane, three places to support the sawtooth on this base plate working face 5 and the engagement of this sawtooth core bar.
Operation principle: honing head assembles the back and is installed on the lathe unit head; During honing, under the effect of machine tool feeding mechanism, the sawtooth core bar is pushed ahead; Base plate working face expansion grinding work piece; When machine tool feeding mechanism was got back to the origin-location, the sawtooth core bar retracted reset condition with the base plate working face under the active force of spring.
When changing the base plate working face, core bar is extracted forward, base plate working face and sawtooth core bar are broken away from fully, can take out the base plate working face.
Claims (1)
1. the flexible automatically honing head of a sawtooth slidingtype; It is characterized in that: the sawtooth core bar is positioned at the honing head overcoat, and stop screw is fixedly connected with the sawtooth core bar, and the groove that this stop screw and honing head put outward is slidingly connected; Spring housing is connected on the sawtooth core bar; The base plate working face is installed in the honing head overcoat front end elongated slot, and this base plate working face adopts zigzag structure and adopts tapering inclined-plane, three places to support the sawtooth on this base plate working face and the engagement of this sawtooth core bar.
