Detailed description of the invention
The following is specific embodiment of the utility model and combine accompanying drawing, the technical solution of the utility model is made further
Description, but this utility model is not limited to these embodiments.
As shown in Figures 1 to 4, this deep hole drill includes:
Knife bar 10, has clamping part 11, the work portion 12 being connected as a single entity, and work portion 12 is upper near clamping part 11 one end
End, work portion 12 is bottom away from clamping part 11 one end, offers two chip areas arranged in Double helix in work portion 12
121, chip area 121 is extended to bottom by upper end, is further opened with the runner 13 for cutting fluid circulation and runner 13 in knife bar 10
Sequentially pass through by clamping part 11, work portion 12；
Blade 20, is plugged in center bottom, deviates from one end, work portion 12 at blade 20 and is provided with point of a knife 21 and point is listed in
Two cutting edges 22 of point of a knife 21 both sides, two cutting edges 22 are tilted down setting relative to point of a knife 21 respectively, and two cutting edges 22 close
In point of a knife 21 centrosymmetry, each cutting edge 22 both sides are provided with knife face 24 after rake face 23, master, and rake face 23 is near point of a knife
21 one end offer curved surface 26, at curved surface 26, rake face 23 side are provided with minor flank 25, rake face 23, curved surface 26 with
And minor flank 25 three intersects two-by-two, rake face 23, cutting edge 22, main after knife face 24, minor flank 25 and curved surface 26 5
Person collectively constitutes a cutting unit, and each minor flank 25 all intersects with knife face 24 after the master in another cutting unit and sets
Putting, all offer chip-breaker 27 after each master on knife face 24, each rake face 23 is further opened with clearance surface away from point of a knife 21 one end
28, two clearance surfaces 28 and two chip area 121 one_to_one corresponding are arranged.
In prior art, when workpiece is carried out deep hole machining, common drill, due to the restriction of drill structure, is not easy to row
Going out produced chip, chip is blocked in hole, affects the processing in hole, and drilling quality is poor, the most also can damage cutter.
To this end, this utility model devises a kind of deep hole drill, clamping part 11 is used for Cutting tool installation manner at corresponding equipment
On, work portion 12 offers double-stranded two chip areas 121, and chip area 121 has been extended to by upper end, work portion 12
Bottom, work portion 12, the chip produced during deep hole machining can be discharged smoothly along two chip areas 121, it is to avoid chip blocking processing
Hole, cause the damage of workpiece and cutter.
Additionally, be further opened with in knife bar 10 sequentially passing through by clamping part 11, the runner 13 in work portion 12, with for cutting
Liquid stream leads to, and during work, cutting fluid flows into from clamping part 11, arrives at blade 20 and workpiece, on the one hand behind work portion 12
The temperature that cutter, workpiece produce in working angles can be reduced, on the other hand can also wash away chip, avoid chip further
The hole of blocking processing, it is ensured that being smoothed out of boring work, it is ensured that the quality in hole.
Being provided with two cutting units on blade 20, two cutting units are centrosymmetric, boring time, blade 20 along with
Knife bar 10 rotates together, and when rotated, two cutting units work simultaneously, accelerates penetration rate and ensures the most again boring
Steadily, cutting effect is good.
During boring, the chip produced under cutting edge 22 acts on is expelled to clearance surface 28 along corresponding rake face 23, connects
The corresponding chip area 121 of entrance, discharge, the setting of rake face 23 can control chip and discharge along both fixed tracks, really
Protect the smooth discharge of chip.
In the discharge process of above-mentioned chip, longer chip can also be cut by the setting of curved surface 26 and chip-breaker 27
Disconnected, it is to avoid long chip is wrapped on cutter along with the rotation of cutter, damage cutter, the carrying out of impact boring work.
It is noted that two cutting edges 22 are tilted down setting relative to point of a knife 21 respectively, hole be the most all the time
In conical surface-shaped, the chip of generation also can be towards the shape evolution of curling, and therefore, arrange in the present embodiment is double-stranded
It is beneficial to the discharge of chip further.
Preferably, it is tiltedly installed with respectively in blade 20 both sides and two clearance surface 28 land 29 one to one, and two-edged
Band 29 is about point of a knife 21 centrosymmetry.
The setting of land 29 can strengthen the intensity of blade 20 to a certain extent, decreases the peripheral milling adding man-hour simultaneously
Damage, it is ensured that the reliability of blade 20 work so that the inner surface fineness in hole to be processed promotes.
It is further preferred that be installed with two mounting blocks 122 being centrosymmetric in bottom, two mounting blocks 122 surround formation
For installing the mounting groove 123 of blade 20, runner 13 is positioned in the middle part of mounting groove 123, and all offers peace on each mounting blocks 122
Dress hole 1221.
Two mounting blocks 122 in the present embodiment and work portion 12 are connected as a single entity settings, the structural and stability of entirety
Good, the setting of mounting groove 123 has been also convenient for the installation of blade 20, during real work, can be loaded by the union piece such as screw, bolt
In corresponding installing hole 1221, blade 20 is fixedly mounted on bottom, work portion 12, it is ensured that blade 20 is firm with work portion 12
Connect, smooth working.
Cutting fluid can be applied directly on blade 20 through runner 13, external pipe need not be used to wash away, action effect
Substantially, practicality is good.
Preferably, being arranged with sleeve 30 at clamping part 11 near one end, work portion 12, in sleeve 30 circumferential lateral surface, symmetry is opened
It is provided with two screwed holes 31, is provided with regulation screw 32 in each screwed hole 31 and regulation screw 32 through sleeve 30 and is resisted against
On clamping part 11.
Owing to the length of knife bar 10 is longer, in order to ensure the stability of knife bar 10 in continual rotation, it is provided with
Sleeve 30, gives knife bar 10 and supports, it is to avoid the fracture of knife bar 10.Regulation screw 32 and screwed hole 31 cooperating, regulating sleeve
Laminating degree between 30 and clamping part 11, facilitates the most again and sleeve 30 is carried out demolition, installation.
This depth drill knife structure is reasonable in design, chip area 121 and the smooth row being provided with beneficially chip of clearance surface 28
Go out, it is to avoid the quality damaging and being effective to ensure that boring of cutter；The setting of curved surface 26 and chip-breaker 27 can be ruptured and be cut
Bits, further ensure that the smooth discharge of chip, and drilling effect is obvious, and practicality is good.
Specific embodiment described herein is only to this utility model spirit explanation for example.This utility model institute
