Description

The spline grinding machine dresser

Technical field

The utility model relates to field of mechanical technique, relates in particular to a kind of dresser.

Background technology

Traditional spline grinding machine dresser is the dresser that designs to the processing rectangular spline, and the grinding wheel shape of its finishing can't be processed the arc groove of splined shaft radial direction.When the spline grinding machine dresser is processed the arc-shaped slot of five equilibrium in the radial direction at spline, need crushing be become R type arc surface, carry out grinding splined shaft five equilibrium arc groove radially again.Yet in the past at the processing splined shaft radially during the arc groove of five equilibrium, the spline grinding machine dresser (as shown in Figure 4) of use is by holder 25, support A26, and bearing A27, packing ring 28, diamond pen A29, screw 30, nut 31 (emery wheel B32) is formed.This trimmer through the cylinder on the holder 25 with bearing A27 on holder 25; Be connected in the dead eye of support A26 by bearing A27 outer ring again; And fastening by packing ring 28 and nut 31, diamond pen A29 is connected by its external diameter in the hole of support A26 upper end and by screw 30 lockings.Because diamond pen A29 only rotates the finishing of accomplishing the abrasive wheel grinding wheel arc face in the cylindrical center that centers on the holder under the support of a bearing A27; Its trimmer diamond pen in dressing process is prone to produce irregular variation with respect to the distance of the cylindrical center on the holder; Thereby cause the abrasive wheel grinding wheel arc face center of being repaired not overlap with lathe two top center lines, so emery wheel (R) the arc surface form accuracy and the dimensional accuracy of finishing all can't be guaranteed.Secondly this trimmer does not have vertical and horizontal governor motion reliability when adjustment is installed low.And the adjustment required time is long and repeat the height of adjusting frequency in process, and operation is inconvenience very.Moreover this trimmer is in dressing process, and the operator is the low order end of support A26 with position that hand is held, so operator's hand is run into grinding wheel spindle easily when finishing, causes potential safety hazard.

Summary of the invention

The objective of the invention is to overcome above-mentioned shortcoming and provide a kind of easy to adjust, simple in structure, the spline grinding machine dresser that the shape of finishing and dimensional accuracy are high.

The purpose of this utility model and solve its technical problem underlying and adopt following technical scheme to realize: a kind of spline grinding machine dresser; Comprise vertical governor motion, lateral adjustment and transmission mechanism, lateral adjustment is made up of base, cover plate, limiting plate, adjustment screw A and lock-screw A; Vertically governor motion by bearing, support, spacingly decide plate A, spacingly decide plate B, adjustment screw B, lock-screw B and diamond pen and form; Wherein: the cover plate of lateral adjustment is connected the gear-box lower end of transmission mechanism, and the external diameter of the upper end of the main shaft through transmission mechanism is connected in the endoporus of bearing of vertical governor motion again; Cover plate and base connecting portion are respectively equipped with engaged U-shaped boss and groove, are provided with limiting plate at the boss position of cover plate, and limiting plate is connected to the base groove position through adjustment screw A; Vertically bearing and the support connecting portion of mechanism are respectively equipped with engaged U-shaped boss and groove, and its end away from main shaft is respectively equipped with spacingly to be decided plate A, spacingly decide plate B, and fixes through adjustment screw B, and said diamond pen is fixed in the hole on the support.

Above-mentioned spline grinding machine dresser, wherein: transmission mechanism is made up of gear-box, handle, rocking arm, little axle, gear A, gear B, main shaft, bearing, bearing block and dust cap, and main shaft is arranged in the bearing block; The bearing block upper and lower end is provided with dead eye; Bearing is housed respectively, and the upper end covers with dust cap, and the lower end is connected with gear-box; The main shaft lower end is stretched in the gear-box, is enclosed within the gear B; Little axle is fixed on the gear-box, and the upper end is connected with rocking arm, and the lower end is connected with the interior gear A of gear-box; Gear A and gear B engagement; Handle is contained on the rocking arm away from the little hole.

The utility model is compared with prior art; Has tangible beneficial effect; Can know from above technical scheme: the utility model only need shake handle when emery wheel is repaired, rocking arm drives little axle, gear A, gear B, main axis rotation successively through transmission mechanism; Thereby diamond pen is back and forth rotated around the alignment of shafts, emery wheel is played the effect of finishing R circular arc.It is simple in structure, easy to adjust, dressing accuracy is high, and it is low to repeat to adjust frequency with the lots processed part, and the installation site is unrestricted, so practicality is better, and the scope of application is wide, is easy to apply.

The specific embodiment of the utility model is provided by following examples and accompanying drawing thereof in detail.
