Abstract
A water-cooled deep hole drilling tool comprises a drill pipe, a drill bit, a drill pipe base and a deep hole drill water knockout drum. The drill bit is located at the front end of the drill pipe, a water channel is formed in the drill pipe in the axial direction, the water channel is a blind hole, the open end of the water channel is arranged at the back end of the drill pipe, and a water outlet hole communicated with the water channel is formed in a position close to the front end of the drill pipe in the radial direction. When the water-cooled deep hole drilling tool is used, cooling liquid flows into the hole bottom of a workpiece to be processed via the water channel of the drill pipe through the water outlet hole to cool the drill bit, a large amount of heat is brought away, and then the cooling liquid overflows from a hole of the workpiece to be processed and flows into a waste liquid collecting container to be filtered to be used repeatedly.
Description
technical field:
The utility model relates to a kind of boring cutter, particularly a kind of water-cooled deep hole drill.
background technology:
When metal is carried out to depth drill, because caloric value is large, as can not be cooling in time, can significantly affect bit life.
summary of the invention:
Given this, be necessary to design a kind of water-cooled deep hole drill.
A kind of water-cooled deep hole drill comprises: drilling rod, drill bit; Wherein, drill bit is positioned at the drilling rod front end, at drilling rod, has water channel on axially, and water channel is blind hole, and its openend is located at the rear end of drilling rod, upwards has the apopore with water channel UNICOM in the footpath near the drilling rod front end, and the drilling rod shaft has chip area.
Preferably, the water-cooled deep hole drill also comprises safety chuck and depth drill water knockout drum, wherein, safety chuck is stepped coaxial clyinder, its top is the lathe clamping part, bottom has the slotted eye be complementary with the drilling rod rear end, axially have the safety chuck water channel with slotted eye UNICOM at safety chuck, and the water channel position consistency of safety chuck water channel position and drilling rod, the depth drill water knockout drum is cylindric, the depth drill water knockout drum is enclosed within the safety chuck middle part and is connected with safety chuck by the bearing that is located at depth drill water knockout drum two ends, oil sealing is equipped with in two bearings inboard between depth drill water knockout drum and safety chuck, have inlet opening on the outer wall at depth drill water knockout drum middle part, the water inlet tap that is connected with at the water inlet position place, water inlet tap has radial hole over against the safety chuck of locating, this hole is connected with the safety chuck water channel.
Preferably, water channel is positioned at the drilling rod middle shaft part, and the safety chuck water channel is positioned at the safety chuck middle shaft part.
Preferably, drill bit and drilling rod are connected as a single entity by welding.
The utility model drilling tool in use, at the bottom of cooling fluid flows into the hole of work piece by the water channel of drilling rod through apopore, and then cooling drill bit, take away amount of heat, afterwards, cooling fluid is from the aperture benefit of work piece, flow to the waste collection container, recycle after filtering.
the accompanying drawing explanation:
Accompanying drawing 1 is that the master of the water-cooled deep hole drill of a width better embodiment looks schematic diagram.
In figure: drilling rod 1, drill bit 2, water channel 11, rear end 12, apopore 13, chip area 14, safety chuck 3, depth drill water knockout drum 4, lathe clamping part 31, slotted eye 32, safety chuck water channel 33, bearing 41, oil sealing 42, inlet opening 43, water inlet tap 44.
the specific embodiment:
As shown in Figure 1 and Figure 2, a kind of water-cooled deep hole drill comprises: drilling rod 1, drill bit 2; Wherein, drill bit 2 is positioned at drilling rod 1 front end, on drilling rod 1 is axial, has water channel 11, water channel 11 is blind hole, its openend is located at the rear end 12 of drilling rod 1, and at the apopore 13 upwards had near the footpath of drilling rod 1 front end with water channel 11 UNICOMs, drilling rod 1 shaft has chip area 14.
In the present embodiment, the water-cooled deep hole drill also comprises safety chuck 3 and depth drill water knockout drum 4, wherein, safety chuck 3 is stepped coaxial clyinder, its top is lathe clamping part 31, bottom has the slotted eye 32 be complementary with drilling rod 1 rear end 12, axially have the safety chuck water channel 33 with slotted eye 32 UNICOMs at safety chuck 3, and water channel 11 position consistency of safety chuck water channel 33 positions and drilling rod 1, depth drill water knockout drum 4 is cylindric, depth drill water knockout drum 4 is enclosed within safety chuck 3 middle parts and is connected with safety chuck 3 by the bearing 41 that is located at depth drill water knockout drum 4 two ends, oil sealing 42 is equipped with in two bearings 41 inboards between depth drill water knockout drum 4 and safety chuck 3, have inlet opening 43 on the outer wall at depth drill water knockout drum 4 middle parts, in inlet opening, 43 positions is connected with water inlet tap 44, water inlet tap 44 has radial hole over against the safety chuck 3 of locating, this hole is connected with safety chuck water channel 33.
In the present embodiment, water channel 11 is positioned at drilling rod 1 middle shaft part, and safety chuck water channel 33 is positioned at safety chuck 3 middle shaft parts.Drill bit 2 is connected as a single entity by welding with drilling rod 1.
