Abstract
The utility model relates to a rock core nesting drilling device, particularly to a drilling tool with a cooling, lubricating and overload protection structure, and belongs to the machine manufacturing field. The drilling tool comprises a taper shank torque shaft and a connection sleeve; the taper shank torque shaft is connected with a hollow core nesting drill through a connection sleeve; the rear part of the taper shank torque shaft has a cooling lubricating fluid leak prevention sleeve; the cooling lubricating fluid leak prevention sleeve has a cooling lubricating fluid hose joint; and the connection sleeve is connected with the hollow core nesting drill through a torque transmission feather key. During the rock core drilling process, the internal recycling cooling and lubricating of the drill cutting and drainaging area is synchronously implemented, thereby achieveing the purpose of stable rotary drilling and promptly washing and drainaging the fine cuttings, and when accident happens in the rock core drilling process, the torque transmission feather key and a bolt are cut down instantly, thus leaving the taper shank torque to be idle, so the failure and the damage to the hollow core nesting drill of a high price are precluded.
Description
Technical field
The utility model relates to a kind of core jacking drilling tool, specifically is a kind of drilling tool with cooling and lubricating and overcurrent protection structure, belongs to mechanical manufacturing field.
Background technology
At present, in the work of application studies such as mining, geological prospecting and building foundation, must carry out the branch sampling to large-scale rock.The core of selected each section of sampling rock deep layer is exactly a widely used physics and chemistry test method in the internal feature observational study.Must use core jacking drilling tool to the sampling of core, the structure of common core jacking drilling tool is that taper shank torque axis and adapter sleeve are one, weak point is, in the process of core drilling, because the The structure of rock difference, some rock is hard especially, expensive hollow treapanning drill was lost efficacy damage, strengthen cost of production, do not had perfect solution so far.
Summary of the invention
The purpose of this utility model is: for overcoming the weak point in the above-mentioned prior art process; a kind of drilling tool with cooling and lubricating and overcurrent protection structure is provided; it comprises taper shank torque axis, adapter sleeve; the taper shank torque axis is connected with the hollow treapanning drill by adapter sleeve; there is the cooling-lubricant leak jacket at the rear portion of taper shank torque axis; the cooling-lubricant hose coupling is arranged on the cooling-lubricant leak jacket, and adapter sleeve transmits flat key by moment of torsion and is connected with the hollow treapanning drill.In the core drilling process, the synchronization implementation drill bit is cut the interior circulation cooling and lubricating in the district that disappears, keep stablizing the purpose of rotary drilling and the quick row of dashing landwaste in small, broken bits, in the process of core drilling when meeting accident bit freezing, moment of torsion transmits flat key and the idle running alone of taper shank torque axis is all cut off, only had to screw at once, so has stopped the inefficacy damage of expensive hollow treapanning drill.
The utility model is realized with following technical scheme: a kind of drilling tool with cooling and lubricating and overcurrent protection structure; it comprises taper shank torque axis, adapter sleeve; it is characterized in that: the taper shank torque axis is connected with the hollow treapanning drill by adapter sleeve; there is the cooling-lubricant leak jacket at the rear portion of taper shank torque axis; the cooling-lubricant hose coupling is arranged on the cooling-lubricant leak jacket, and adapter sleeve transmits flat key by moment of torsion and is connected with the hollow treapanning drill.
The two ends up and down of described taper shank torque axis and cooling-lubricant leak jacket have ball bearing respectively.
Also has the leakproof seal circle on the described taper shank torque axis.
Described moment of torsion transmits flat key and is connected by screw with adapter sleeve.
The utility model has the advantages that: the taper shank torque axis is connected with the hollow treapanning drill by adapter sleeve, there is the cooling-lubricant leak jacket at the rear portion of taper shank torque axis, the cooling-lubricant hose coupling is arranged on the cooling-lubricant leak jacket, in the core drilling process, the synchronization implementation drill bit is cut the interior circulation cooling and lubricating in the district that disappears, keep stablizing rotary drilling and the quick row of dashing landwaste in small, broken bits, in the process of core drilling when meeting accident bit freezing, moment of torsion transmits flat key and screw is all cut off at once, the idle running of taper shank torque axis is only arranged, therefore stopped the inefficacy damage of expensive hollow treapanning drill.
Description of drawings
Below in conjunction with the drawings and the specific embodiments the utility model is described in further detail.
Accompanying drawing is the utility model structural representation:
Among the figure: 1, taper shank torque axis, 2, the leakproof seal circle, 3, the cooling-lubricant hose coupling, 4, moment of torsion transmits flat key, 5, adapter sleeve, 6, ball bearing, 7, the cooling-lubricant leak jacket, 8, ball bearing, 9, the hollow treapanning drill, 10, screw.
The specific embodiment
As shown in the figure: taper shank torque axis 1 docks with acorde bur hole machine tool main transmission axis of cone cover, and by moment of torsion transmission flat key 4 and adapter sleeve 5 rotation torque is passed to hollow treapanning drill 10, drills through the cylindrical core that availability test uses on rock.In order to reduce the heating jam and the excessive wear of hollow treapanning drill, in the process of core drilling, all the time constantly pumped into the pressure cooling-lubricant by hose coupling 3, cooling-lubricant is through cooling-lubricant leak jacket 7, taper shank torque axis 1 radial hole and central tube then, finally enter expensive hollow treapanning drill cutting region, keep stablizing rotary drilling and the timely row of dashing landwaste in small, broken bits.The two ends of taper shank torque axis 1 and cooling-lubricant leak jacket 7 have ball bearing 6,8 respectively, in addition, in the process of core drilling when meeting accident bit freezing, moment of torsion transmits flat key 4 and 1 idle running of taper shank torque axis is all cut off, only had to screw at once, has therefore stopped the inefficacy damage of expensive hollow treapanning drill.
