In metal cutting, the processing in hole occupies significant proportion, and some precise parts for the machining accuracy of hole position will
Ask also very high, but the accuracy of some deep hole machinings is but difficult to hold.In most drilling techniques, it is direct drive drill bit
Metallic element is processed, drill bit is easy to generation in running and rocks, or even deformation, cause mismachining tolerance big,
So in deep hole processing, its concentricity and accuracy are difficult to ensure that；Often due to the rocking of drill bit, gold in actual production
The impact of the factor such as hardness is uneven of category material, causes skew, the deformation of drill bit, processes inclined hole, hole bigger than normal so that gold
Category parts are scrapped, and when the deformation of drill bit is excessive, even result in the fracture of drill bit.
【Content of the invention】
In view of this, for overcoming the deficiencies in the prior art, the present invention to provide a kind of depth drill auto-guider, which is effective
Solve in deep hole processing, situations such as rocking, deform of lengthening drill bit appearance, it is ensured that the precision of processing improves machinery
The quality of processing, meanwhile, also extend the service life of drill bit.
For achieving the above object, technical scheme is as follows：
A kind of depth drill auto-guider, including cylinder, connecting plate, support, guide pin bushing bearing and is arranged at described leading
Fairlead inside set bearing, described connecting plate one end are connected to the cylinder, and the connecting plate other end is connected to described
Frame side, the guide pin bushing bearing are connected to the mid-stent, and the guide pin bushing holder top is provided with bearing block, in the bearing block
Portion is provided with rolling bearing and locking nut, and the locking nut is mutually butted on the housing washer, the rolling bearing endoporus
Sealing shroud is provided with, the sealing shroud is concentric with the fairlead, lengthening drill bit sequentially passes through the sealing shroud and the guiding
Set, effectively prevent lengthening drill bit rocking when drilling rotates.
Preferably, the fairlead lower end is provided with circle shape groove.
O-ring seal is provided with the groove, when drilling is processed, the fairlead lower end is mutually butted on parts to be processed
Better seal is played on surface, the O-ring seal, is conducive to the delay of cutting fluid, is easy to cool to drill bit.
Further, through hole is provided with the middle part of the guide pin bushing bearing, the through hole runs through the fairlead and the sealing shroud,
When drilling is processed, chip area that iron filings are arranged from drill bit is discharged, and is discharged to outside through the through hole, it is to avoid iron filings are obstructed
Cause the fracture of drill bit.
The present invention design principle be：Based on rocking that lengthening drill bit occurs when drilling rotates, design and produce one with
The concentric fairlead of bit upper end holds the lower end of lengthening drill bit, it is to avoid lengthening drill bit is rocked, it is ensured that its concentricity, enters one
Step ensure that the precision of machining, improve the quality of machining；Simultaneously by the design of simple structure, O-ring seal
Sealing, be conducive to the delay of cutting fluid, preferably cool down to drill bit, increase the service life.
The invention has the beneficial effects as follows, it is ensured that the precision of machining, the quality of machining is improve, brill is extended
The service life of head.

【Specific embodiment】
Accompanying drawing in below in conjunction with the embodiment of the present invention, to the embodiment of the present invention in technical scheme carry out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiment.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
With reference to Fig. 1, Fig. 2 and Fig. 3, a kind of depth drill auto-guider, including cylinder 1, connecting plate 2, support 3, guide pin bushing
Bearing 4 and the fairlead 5 being arranged inside the guide pin bushing bearing 4,2 one end of the connecting plate is connected to the cylinder 1, described
2 other end of connecting plate is connected to 3 side of the support, and the guide pin bushing bearing 4 is connected in the middle part of the support 3, the guide pin bushing
4 tops of seat are provided with bearing block 6, are provided with rolling bearing 9 and locking nut 8 inside the bearing block 6, and the locking nut 8 offsets
In 9 outer ring of the rolling bearing, 9 endoporus of the rolling bearing is provided with sealing shroud 7, and the sealing shroud 7 is coaxial with the fairlead 5
The heart, lengthening drill bit 12 sequentially pass through the sealing shroud 7 and the fairlead 5, effectively prevent lengthening drill bit 12 and rotate in drilling
When rock.
5 lower end of the fairlead is provided with circle shape groove 10.
O-ring seal 11 is provided with the groove 10, when drilling is processed, 5 lower end of the fairlead is mutually butted on to be processed
Better seal is played on 13 surface of parts, the O-ring seal 11, is conducive to the delay of cutting fluid, is easy to lengthening drill bit
