Abstract
A kind of depth drill guide sleeve structure, including the accommodating cavity on guide sleeve and guide sleeve, the guide sleeve includes tool assembly, positioning body and the guide way on same axis, the top of the guide way is equipped with groove, the groove and accommodating cavity are located on same axis, the groove is equipped with alloy head, and the guide sleeve being made of tool assembly, positioning body and guide way is integrally formed.Drill bit is oriented to by the utility model, avoids drill bit in the bounce of processing, to guarantee the precision of depth drill, and drill bit is protruded on smaller deeper Working position and carries out drilling processing.Meanwhile in the front end embedded alloy material of guide sleeve, avoid drill bit that with guide way friction, the service life of the utility model directly can be improved.
Description
Technical field
The utility model relates to field of machining and machinebuilding technology, and in particular to a kind of depth drill guide sleeve structure.
Background technique
In production mould, need to often be processed on mold draw ratio reach decades of times deep hole, this manufacturing procedure into
Process poor rigidity since drill bit is elongated when capable depth drill processing, drill bit is easy to produce bounce so that drill bit be easy to break and
The borehole accuracy processed is difficult to ensure, general in traditional processing that bottom outlet is first processed on deep hole drilling and boring machine, then turns sequence
Suitable pilot hole is processed according to aperture to horizontal lathe, then returns to and bores the application-oriented hole continuation Boring of boring machine.
Though the method can be reduced quality problems caused by causing hole to train off as cutter positioning guiding inaccuracy by the application of pilot hole,
But process length is also increased simultaneously and has dispersed process concentration degree, reduces production efficiency and utilization rate of equipment and installations, and workpiece
Clamping repeatedly, correction reduce part processing precision, increase the labor intensity of operator.
Utility model content
For overcome the deficiencies in the prior art, a kind of depth drill guide sleeve structure provided by the utility model.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of depth drill guide sleeve structure, including the accommodating cavity on guide sleeve and guide sleeve, the guide sleeve includes being located at
The top of tool assembly, positioning body and guide way on same axis, the guide way is equipped with groove, the groove and accommodating cavity
On same axis, the groove is equipped with alloy head, the guide sleeve one being made of tool assembly, positioning body and guide way
It is body formed.
In the present invention, the positioning body includes the rotary table connecting with guide way and the cylinder that connect with tool assembly.
In the present invention, the diameter of the cylinder is greater than the maximum gauge of rotary table.
In the present invention, the outer profile diameter of the tool assembly is less than body diameter.
In the present invention, the diameter of the guide way is less than the outer profile diameter of tool assembly.
In the present invention, the frustoconical bevel angle of the rotary table is θ, and the value range of the θ includes 115 ° ~ 125 °.
In the present invention, the tool assembly is equipped with the taper locating slot for fixing depth drill.
In the present invention, the positioning body and tool assembly are orthogonal with accommodating cavity respectively.
The utility model has the beneficial effects that being oriented to by the utility model to drill bit, avoid drill bit in the jump of processing
It is dynamic, to guarantee the precision of depth drill, and allow drill bit protrude on smaller deeper Working position carry out drilling plus
Work.Meanwhile in the front end embedded alloy material of guide sleeve, avoid drill bit that with guide way friction, it is practical new that this directly can be improved
The service life of type.
Detailed description of the invention
The present invention will be further described with embodiment with reference to the accompanying drawing:
Fig. 1 is the structural schematic diagram of the present embodiment；
Fig. 2 is the structural schematic diagram of another angle of the present embodiment.
Specific embodiment
It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer
Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
Referring to Figures 1 and 2, for placing deep hole on a kind of depth drill guide sleeve structure, including guide sleeve 1 and guide sleeve 1
The accommodating cavity 2 of brill, the guide sleeve 1 include tool assembly 3, positioning body 4 and the guide way 5 on same axis, the guiding
The top of body 5 is equipped with alloy head 7.Further, the top of the guide way 5 is equipped with groove 6, the groove 6 and accommodating
Chamber 2 is located on same axis, and the alloy head 7 that the guide way 5 is equipped with is arranged in groove 6, and alloy head 7 can be to avoid in deep hole
It bores abrasion guide way 5 during rotation to damage, improves the service life of the utility model.Further, described
It is integrally formed by the guide sleeve 1 that tool assembly 3, positioning body 4 and guide way 5 form, and the positioning in integrally formed guide sleeve 1
Body 4 and tool assembly 3 are orthogonal with accommodating cavity 2 respectively, it is ensured that concentricity of the utility model clamping on lathe further drops
Mismachining tolerance when low depth drill is processed.
Preferably, the positioning body 4 includes the rotary table 41 connecting with guide way 5 and the cylinder 42 connecting with tool assembly 3；And
The diameter of the cylinder 42 is greater than the maximum gauge of rotary table 41；The frustoconical bevel angle of the rotary table 41 is θ, the value range of the θ
Including 115 ° ~ 125 °, and θ=120 ° in the present invention, above structure can make the utility model preferably be mounted on lathe
On.
Preferably, the outer profile diameter of the tool assembly 3 is less than 42 diameter of cylinder, and the diameter of the guide way 5 is less than work
Fill the outer profile diameter of body 3.
Preferably, the tool assembly 3 is equipped with taper locating slot 8 for fixing depth drill, and taper locating slot 8 can be
When the utility model is packed into drill bit, lathe is more effective to the clamping of drill bit, reduces drill bit and loosens the feelings fallen in use
Condition occurs.
Above description is merely a prefered embodiment of the utility model, as long as realizing the utility model with essentially identical means
The technical solution of purpose belongs within the protection scope of the utility model.
