Description
Technical field
The utility model relates generally to parts manufacture field, especially a kind of boring cutter movable axis and single-blade fine boring cutter.
Background technique
In modern CNC machining, boring cutter is widely used in bore hole operation.
The fixation of existing fine boring cutter is fixed by the work face contact of half ripple pearl screw and movable axis.This kind of fixed form
It is easy to happen skidding in fine boring cutter work, the precision of processing is further reduced, provides the rejection rate of product.
Because in consideration of it, special propose this utility model.
Utility model content
It is good that the purpose of the utility model is to provide locking properties when a kind of use, is not easy the boring cutter movable axis to skid and boring
Knife.
To achieve the goals above, a kind of boring cutter movable axis provided by the utility model, the boring cutter movable axis are tubular
Structure, one end of the tubular construction is configured with a connection structure, for connecting blade bearing；
The tube conformation of the one end of tubular construction far from connection structure has the internal screw thread for connecting dial；
The connection structure is the protruding portion of a bar shaped, and the central configuration of protruding portion has a mounting hole；
It is configured to an inclination conical surface in the side that tubular construction corresponds to protruding portion one end, in tubular construction and the inclination conical surface
Opposite side is configured with a waist-shaped hole, and the long axis direction of the waist-shaped hole and the axis direction of tubular construction are parallel.
Preferably, several are constructed out on the cylinder between the inclination conical surface and the waist-shaped hole of the boring cutter movable axis to be used for
Bear the gap of deformation.
On the other hand, the utility model additionally provides a kind of single-blade fine boring cutter, the boring cutter movable axis of the single-blade fine boring cutter
For above-mentioned boring cutter movable axis.
Boring cutter movable axis and single-blade fine boring cutter provided by the utility model, have the advantages that：
The working face of the inclination conical surface is to be not easy to skid when the contact of half ripple pearl screw, and tightness is good, the processing for part
Precision is high, while extending the service life of equipment.

Specific embodiment
The utility model is described further with reference to the accompanying drawings and detailed description.
Embodiment one
Fig. 1-3 is please referred to, the utility model embodiment provides a kind of boring cutter movable axis.
The boring cutter movable axis is a tubular construction 1.
One end of tubular construction 1 is equipped with a connection structure, and in the present embodiment, the connection structure is the protrusion of a bar shaped
Portion 2,2 central configuration of protruding portion have a mounting hole 3, and the mounting hole 3 is for connecting blade bearing.
Tube conformation in the one end of tubular construction 1 far from connection structure has internal screw thread 4, and the internal screw thread 4 is used for and quarter
Scale connection.Allow user of service that movable axis to be driven to move on 1 axial direction of tubular construction in rotation scale.
In the side of corresponding 2 one end of protruding portion of tubular construction 1, it is configured with an inclination conical surface 5.The design of the inclination conical surface 5
Contact of incline plane when contacting half ripple pearl screw of the fixed movable axis of boring cutter and the inclination conical surface 5 can make movable axis fixed more
Step up admittedly, to be not easy to loosen skidding.The stability of boring cutter work in-process is improved, and then improves machining accuracy and service life.
A waist-shaped hole 6, and the long axis of the waist-shaped hole 6 are configured in the side opposite with the inclination conical surface 5 of tubular construction 1
It is parallel with the axis of tubular construction 1.
The waist-shaped hole 6 further fixes the position of movable axis and makes movable axis can be in tubular knot for penetrating for screw
It is moved on 1 axial direction of structure.
Several gaps 7 are also constructed on the barrel of tubular construction between the inclination conical surface 5 and waist-shaped hole 6, for holding
By the deformation that the inclination conical surface 5 is generated when being oppressed by half ripple pearl screw, the service life of movable axis is further increased.
Embodiment two
The utility model embodiment provides a kind of single-blade fine boring cutter.The basic structure of the single-blade fine boring cutter with it is existing
Single-blade fine boring cutter is identical, and details are not described herein again, and the difference with existing single-blade fine boring cutter is, the single-blade in the present embodiment
The movable axis of fine boring cutter is the boring cutter movable axis provided in embodiment one.
Specific case used herein elaborates utility model design, and the explanation of above embodiments is
It is used to help understand the core concept of the utility model.It should be pointed out that for those skilled in the art,
Under the premise of not departing from utility model design, any obvious modification, equivalent replacement or the other improvements made should all
It is included within the scope of protection of this utility model.
