Abstract
The utility model discloses a drill bit with a coolant channel. The drill bit with the coolant channel comprises a drill bit body, wherein the drill bit body comprises a handle portion for clamping, a guide portion and a cutting portion, the center of the handle portion of the drill bit body is provided with a channel for coolant to pass through, the channel comprises a plurality of channel outlets which are evenly formed in the upper end circumference of the guide portion, one side of the upper end of the guide portion is further provided with a temperature inductive probe, the output end of the temperature inductive probe is connected with a control switch of a coolant system, and the outlet of the coolant system is arranged above the channel. According to the drill bit with the coolant channel, the channel is formed inside the drill bit, and the coolant can cover the circumferential surface of the whole drill bit, so that the cooling effect is good; besides, a temperature inductive probe is additionally arranged to control the on-off and the flow of the coolant, so that the control is more accurate and waste of the coolant can be avoided.
Description
Technical field
The utility model relates to machine tools, particularly a kind of drill bit with cooling passage.
Background technology
Drill bit, in the process of using, because High Rotation Speed produces a lot of heats, in order to improve service efficiency and life-extending, all will be used cooling fluid.And cooling fluid due to temperature control is inaccurate in the process of using just easily caused waste, and sprays from outside toward drill bit the circumferential surface that cooling fluid is also not easy to cover whole drill bit.
Utility model content
The utility model technical issues that need to address are to spray from outside toward drill bit the circumferential surface that cooling fluid is not easy to cover whole drill bit, and due to temperature control is inaccurate, easily cause waste.
For solving the problems of the technologies described above, the utility model provides a kind of drill bit with cooling passage, comprise drill body, described drill body comprises the shank for clamping, guide part and cutting portion, on the outer surface of described guide part, be provided with a plurality of spiral chip pockets, at the shank center of described drill body, be provided with the passage passing through for cooling fluid, described passage comprises a plurality of channel outlet, and a plurality of described channel outlet are evenly positioned on the upper end circumference of described guide part, in the upper end of described guide part one side, be also provided with temperature sense probe, the output of described temperature sense probe is connected to the gauge tap of coolant system, the outlet of described coolant system is positioned at the top of described passage.A kind of drill bit with cooling passage of the present utility model, by passage being set at drill bit internal, the outer surface that passes through and be sprayed onto drill bit below through cooling fluid from passage carrys out cooling drill bit, cooling fluid can cover the circumferential surface of whole drill bit, good cooling results, and increase temperature sense probe, control switch and the flow of cooling fluid, it is more accurate to hold, and has also avoided the waste of cooling fluid.
As optimal technical scheme of the present utility model, described channel outlet is 3, and between channel outlet and passage, all by the circular arc passageway being bent upwards, is connected described in each.The circular arc passageway being bent upwards can avoid cooling fluid to spraying at a distance, can be directly along the chip pocket of guide part, flows to cutting portion, to whole drill bit, carries out cooling.
Wherein, the position of described temperature sense probe is lower than the position of described channel outlet, and described temperature sense probe is arranged on the electric drill body that described drill body is installed, and described coolant system is also arranged on described electric drill body.The position of temperature sense probe is lower than the position of described channel outlet detecting temperature more accurately.
A kind of drill bit with cooling passage of the present utility model, cooling fluid by be arranged on the passage of drill bit internal drill bit is carried out cooling, good cooling results not only, also can avoid the waste of cooling fluid, and coolant system pops one's head in to control by temperature sense, more accurate, more practical, also more environmental protection.

The specific embodiment
Below in conjunction with accompanying drawing, describe optimal technical scheme of the present utility model in detail.
As shown in the figure, a kind of drill bit with cooling passage of the present utility model, comprise drill body 1, described drill body 1 comprises the shank 2 for clamping, guide part 3 and cutting portion 4, on the outer surface of described guide part 3, be provided with a plurality of spiral chip pockets 5, at shank 2 centers of described drill body 1, be provided with the passage 6 passing through for cooling fluid, described passage 6 comprises three channel outlet 7, described in each, between channel outlet 7 and passage 6, all by the circular arc passageway 11 being bent upwards, be connected, and a plurality of described channel outlet 7 are evenly positioned on the upper end circumference of described guide part 3, in the upper end of described guide part 3 side, be also provided with temperature sense probe 8, the output of described temperature sense probe 8 is connected to the gauge tap 10 of coolant system 9, the outlet of described coolant system 9 is positioned at the top of described passage 6, the position of wherein said temperature sense probe 8 is lower than the position of described channel outlet 7, described temperature sense probe 8 is arranged on the electric drill body 12 that described drill body 1 is installed, described coolant system 9 is also arranged on described electric drill body 12.
A kind of drill bit with cooling passage of the present utility model, by passage being set at drill bit internal, the outer surface that passes through and be sprayed onto drill bit below through cooling fluid from passage carrys out cooling drill bit, cooling fluid can cover the circumferential surface of whole drill bit, good cooling results, and increase temperature sense probe, control switch and the flow of cooling fluid, it is more accurate to hold, and has also avoided the waste of cooling fluid; The circular arc passageway being simultaneously bent upwards can avoid cooling fluid to spraying at a distance, can be directly along the chip pocket of guide part, flows to cutting portion, to whole drill bit, carries out cooling.
The position of temperature sense probe is lower than the position of described channel outlet detecting temperature more accurately.
A kind of drill bit with cooling passage of the present utility model, in the process of work, drill body is first started working, under the monitoring of temperature sense probe, when temperature reaches certain numerical value, the gauge tap of opening coolant system, coolant system is started working, and coolant system can arrange several traffic class simultaneously, under the monitoring of temperature sense probe, when temperature progressively raises, can increase the coolant rate of coolant system, to guarantee drill bit normal operation.
A kind of drill bit with cooling passage of the present utility model, cooling fluid by be arranged on the passage of drill bit internal drill bit is carried out cooling, good cooling results not only, also can avoid the waste of cooling fluid, and coolant system pops one's head in to control by temperature sense, more accurate, more practical, also more environmental protection.
