On the output shaft of dynamic motor.
Further, the workpiece rotation clamp assembly has at least two, and at least two workpiece rotation clamp assembly is simultaneously arranged
Put, the travelling gear of at least two workpiece rotation clamp assembly is eaten peach and be connected with described.
Further, bearing above is located at the top of the half-arc groove, and top bearing cover is connected with bearing, position
Bearing in lower section is located at the bottom of the half-arc groove, and lower bearing end cap connects with bearing.
Further, described stationary fixture component includes main flow guidance tape, side runner plate and upper cover plate, the sprue
Plate is L-type, and the side runner plate both sides are provided with counterbore, and there are a boss, the sprue in the centre of the side runner plate
Plate end and side runner plate end connect, and two pieces of main flow guidance tapes and two pieces of side runner plates are stitched together and become a centre
The square container of hollow out；The workpiece rotation clamp assembly is arranged in the groove of main flow guidance tape, and the workpiece rotates clamping group
Part is located among square container, and upper cover plate is arranged on main flow guidance tape, and the upper cover plate is against on workpiece rotation clamp assembly.
The present invention technical concept be：Motor can not stalled by chain gear transmission drive drill point in whole honing process, is made
Obtain drill point honing evenly, so as to improve the surface quality of cutter, improve the mechanical property of cutter；It is branched by a motor driven
Drill point rotates, more compact structure, and honing is more efficient.
Beneficial effects of the present invention are mainly manifested in：Drill point is rotatable, honing is more uniform, honing effect is preferable.
