Abstract
The utility model relates to a transmission locking structure of a fine-adjustment head for a boring bar, comprising a body which is provided with two combined faces. The two combined faces are communicated with each other through a penetrating transverse through hole and a spacing groove, a fine-adjustment component is assembled into the spacing groove by a convex column in a sliding mode, and the end face of a fine-adjustment screw of the fine-adjustment component is provided with a concave circular groove and a screw hole. A blade bearing is provided with a convex circular part and a through hole, is assembled in the concave annular groove and is locked by screws. The blade bearing supports against the leaning face of the body and is provided with a supporting part which clings to the leaning face of the body. A screw lock locks a fine-adjustment fixing screw and presses the plane of the fine-adjustment screw inclined relative to the screw lock. When the fine-adjustment fixing screw presses the plane of the fine-adjustment screw, forcing feed and lateral component force are generated so that the generation of vibration is effectively restrained.
Description
Technical field
The utility model provides a kind of boring device, refers to a kind of fine setting head for boring bar transmission lock fixing structure especially.
Background technology
Bore hole occupies considerable status on machining, because of general workpiece processing, except external diameter, Surface Machining, be exactly bore hole processing, but because the head for boring bar of bore hole processing all is the inside processing of going deep into to the hole, so all can only adopt cantilever basically, long more according to the mechanics upper cantilever is exactly that the arm of force is elongated, so if blade has vibrations slightly, through the amplification of the arm of force, will cause even more serious vibrations situation, and if bore hole have vibrations also can cause the situation of shake cutter, machined surface does not just have out of roundness and smoothness, and precision also has inaccurate situation.
The fine setting head for boring bar that it is commonly used now, it all is with screw this blade bearing that locks, in any case but locking always has a limit, be exactly to have a little gap that can't discover in the processing of reality, so still can cause the situation of vibrations, make the precision of fine setting head for boring bar commonly used can't promote, finished surface also can't require out of roundness always.
Summary of the invention
The utility model purpose is, a kind of fine setting head for boring bar transmission lock fixing structure is provided, and to solve above-mentioned technical problem point, by the feeding of packing and the generation of side component, is produced and effectively suppress these vibrations, and machining accuracy and out of roundness are promoted.
The technical characterstic of dealing with problems: a kind of fine setting head for boring bar transmission lock fixing structure is provided, it is characterized in that, include:
One body, this body is provided with a blade bearing combinatorial surface, a fine-tuning nut combined planar, connects the horizontal perforation of this blade bearing combinatorial surface to this fine-tuning nut combined planar, inner hole surface one side of this horizontal perforation is provided with one and connects the stopper slot of this blade bearing combinatorial surface to this fine-tuning nut combined planar, this blade bearing combinatorial surface according to blade bearing by hold the position be provided with one perpendicular to the blade bearing combinatorial surface by holding face, this body side face is provided with a fine setting fixing threaded hole screw lock one fine setting fixed screw perpendicular to this horizontal perforation, and this fine setting fixing threaded hole connects to this horizontal perforation;
One fine setting member, this fine setting member front end spiral shell is provided with a fine adjustment screw, all sides of this fine adjustment screw are provided with a projection, this projection is sheathed on this stopper slot movably, the surface of this fine adjustment screw is provided with a plane, this plane this fine setting fixed screw of an angle subtend that tilts, the end face of this fine adjustment screw is provided with a concave ring groove and a screw; And,
One blade bearing for blade locking, this blade bearing lock is established and is provided with a projecting ring section and a through hole to the position of this fine adjustment screw, this projecting ring section card group is in the concave ring groove of fine adjustment screw, and this through hole is worn the screw that passes through a screw and secure to this fine adjustment screw, this blade bearing is provided with one by the position of holding face and supports the plane by being held in this, this front end that supports the plane forms the support division on an outstanding plane, this support division is closely against body by holding face, this blade bearing support division be close to body by holding face, this fine adjustment screw plane that this fine setting fixed screw screw lock and urging tilts in it.
Wherein, this blade is deserted blade.
Though this fine adjustment screw has the projection restriction can not rotate, but still have small therebetween to a little gap that can't find, this fine setting fixed screw urge this and the fine adjustment screw plane of inclination the time, the feeding of packing and the generation of side component are arranged, be able to effective vibration-inhibition and produce.
The effect of contrast prior art: fine setting head for boring bar transmission lock fixing structure of the present utility model, its this blade bearing lock is established to this fine adjustment screw, this blade bearing is provided with one and supports the plane by holding face by being held in this body, this front end that supports the plane forms the support division on an outstanding plane, must be closely against body by holding face with this support division, this blade bearing support division promptly be close to originally body by holding face, screw lock lock this fine setting fixed screw urge this and the fine adjustment screw plane of inclination, make its support division that was promptly pasting originally make it have downward side branch defeating, the generation that shakes in the time of so can suppressing bore hole, though this fine adjustment screw has the projection restriction can not rotate, but still have small therebetween to a little gap that can't find, so this fine setting fixed screw urge this and the fine adjustment screw plane of inclination the time, the feeding of packing and the generation of side component are just arranged, produced and effectively suppress these vibrations, and machining accuracy and out of roundness are promoted.
