Description
Technical field
The utility model belongs to field of machining, and in particular to a kind of attachment structure of accurate bore hole unit.
Background technology
Accurate bore hole unit is a part for fine boring tool, is exactly the part on adjustment fine boring tool, is individually divided
Separate out to manufacture, turn into a separate unit.When needing to make fine boring cutter, according to the requirement in right boring hole, accurate boring
Hole unit is placed into the position of needs.
In field of machining, with the precision more and more higher of modern industry product, to the requirement on machining accuracy of parts
Also more and more higher, also more and more higher, existing accurate bore hole unit only have two to the Adjustment precision requirement to process tool mostly
Deformation groove is used cooperatively, and after installation, overall structure stability deficiency, Adjustment precision is low, complicated.
Utility model content
The purpose of this utility model is to provide a kind of back lash that can eliminate screw thread, simple in construction and Stability Analysis of Structures
The high accurate bore hole unit of property.
For the above-mentioned purpose, major technique solution of the present utility model is to provide a kind of connection of accurate bore hole unit
Structure, including elastic housing, the intermediate sleeve being arranged in elastic housing and by being threadably mounted in the threaded interior hole of intermediate sleeve
Screw rod, intermediate sleeve bottom is provided with dial, and screw tip is provided with blade, and two first deformations are wherein formed with elastic housing
Groove, two second deformation grooves being used in conjunction with each other with two first deformation grooves are formed with intermediate sleeve, the is also formed with intermediate sleeve
Three deformation grooves, two first deformation grooves and two second deformation grooves are each perpendicular to intermediate sleeve axial direction, the 3rd deformation groove and intermediate sleeve
Axial direction is identical.
As an improvement blade is connected by screw in screw tip, screw fastening, improving stability.
As an improvement elastic housing material is spring steel, spring steel has excellent combination property, elastic deformation
Ability is higher.
As an improvement the scale division value on dial is 0.01mm, degree of regulation is high, and chip is more accurate.
The utility model beneficial effect is：By three, deformation grooves are mutual and the material stiffness of elastic housing itself coordinates
Use, that is, complete installation positioning and eliminate thread pitch, have it is simple in construction, structural stability is high and cutting precision is high
Advantage.
Brief description of the drawings
Fig. 1 is the structural representation of the embodiment of the utility model one,
Fig. 2 is the graduated disk structure schematic diagram in Fig. 1 embodiments,
In figure：Elastic housing 1, dial 2, screw rod 3, blade 4, first deform groove 5, second and deform the deformation groove of groove the 6, the 3rd
7。
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, every other embodiment that those of ordinary skill in the art are obtained all belongs to
In the scope of the utility model protection.
As depicted in figs. 1 and 2, the attachment structure of a kind of accurate bore hole unit described by the present embodiment, including outside elasticity
Shell 1, the intermediate sleeve 2 being arranged in elastic housing 1 and the screw rod 3 by being threadably mounted in the threaded interior hole of intermediate sleeve 2, it is middle
Covering 2 bottoms and be provided with dial, the top of screw rod 3 is provided with blade 4, and two first deformation grooves 5 are wherein formed with elastic housing 1, in
Between be formed with set 2 be used in conjunction with each other two second deformation grooves 6 of two first deformation grooves 5, be also formed with the 3rd in intermediate sleeve 2
Deform groove 7, two first deformation grooves 5 and two second deformation grooves 6 are each perpendicular to intermediate sleeve 2 axially, the 3rd deformation groove 7 with it is middle
It is identical to cover 2 axial directions.During installation, because of the effect of the 3rd deformation groove 7 in intermediate sleeve 2 so that intermediate sleeve 2 can load outside elasticity
Shell 1, because the barb design that the 3rd deformation groove 7 carries makes intermediate sleeve 2 can be mounted to the inside of elastic housing 1.The inner side of intermediate sleeve 2
After having accurate thread, screw rod 3 to load intermediate sleeve 2, the 3rd deformation groove 7 supports outward elongates the second deformation groove 6 of intermediate sleeve, simultaneously
The deformation of second deformation groove 6 is limited by the internal precision screw thread of intermediate sleeve 2, forces the first of elastic housing 1 to deform groove 5 and becomes
Shape.All the time in deformation state, the resistance of deformation of the material of elastic housing 1 in itself is counter to be made elastic housing 1 after being assembled due to right boring unit
The second deformation groove 5 in intermediate sleeve 2, intermediate sleeve 2 were both complete simultaneously by the pressure of elastic housing 1 and the resistance of screw rod 3
Thread pitch is eliminated again into installation positioning, simple in construction, structural stability is high.
As an improvement embodiment, blade 4 is connected by screw on the top of screw rod 3, screw fastening, lifting
Stability.
As an improvement embodiment, the material of elastic housing 1 is spring steel, and spring steel has excellent synthesis
Performance, the ability of elastic deformation are higher.
As an improvement embodiment, the scale division value on dial is 0.01mm, and degree of regulation is high, and chip is more
Precisely.
The utility model is not limited to above-mentioned preferred forms, and anyone can draw under enlightenment of the present utility model
Other various forms of products, however, make any change in its shape or structure, it is every that there is same as the present application or phase
Approximate technical scheme, all falls within the scope of protection of the utility model.
