Description
Technical field
The present invention relates to a kind of fluted drill with cooling body, belong to machining tool technical field.
Background technology
Fluted drill be by the rotary cutting of its relative fixed axis with the instrument of the circular hole of drilling workpiece, be similar to fried dough twist because of its chip area curl and gain the name.Fluted drill comprises drillstock and drill bit, and drill bit comprises spirality drill lip and drill flute, and drill flute is mainly used in chip removal.Long-time punching, needs to exit fluted drill from hole, to add cooling fluid in hole.
Its weak point is: cooling fluid directly accesses in the machining hole of workpiece, easily pollutes or corrosion workpiece; On the other hand, need in the course of work frequently to exit fluted drill, have a strong impact on its operating efficiency.
Summary of the invention
The object of the invention is to overcome deficiency of the prior art, a kind of fluted drill with cooling body is provided, to solve in prior art cooling fluid directly and absorption surface, the technical problem of cause workpiece easily to pollute, corroding.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: the fluted drill of band cooling body, comprise drillstock and drill bit, described drill bit is provided with spirality drill lip and drill flute, cooling liquid flowing channel is provided with in described drill bit, cooling liquid flowing channel comprises feed liquor runner and returns liquid runner, and the liquid outlet of feed liquor runner is connected with the inlet returning liquid runner; The inlet of described feed liquor runner connects the liquid outlet of cooling fluid pumping system, and the liquid outlet of described time liquid runner connects the inlet of cooling fluid pumping system.
Described feed liquor runner, time liquid runner are offered along the drill lip hand of spiral respectively.
Described cooling fluid pumping system comprises casing, circulating pump, circulating cooling pipeline and arranges circulating cooling pipeline at magnetic valve, described circulating cooling pipeline coils with in casing twist, is provided with the cooling agent cooling fluid in circulating cooling pipeline being carried out to circularly cooling in described casing.
Described circulating pump is connected with frequency converter, the liquid outlet place of described time liquid runner is provided with the first temperature sensor, described first temperature sensor, frequency converter be connection control unit respectively, control the temperature that single cloud transmits according to the first temperature sensor, control frequency converter operating frequency, thus change the flow velocity of cooling fluid in circulating pump.
Described casing is also provided with the second temperature sensor for measuring coolant temperature, the second temperature sensor is also connected with described control unit signal, and the temperature that the second temperature sensor transmits exceeds the preset temperature upper limit, then cooling agent is changed in control unit prompting.
Described first temperature sensor, the second temperature sensor are connected with control unit signal respectively by wireless network.
Compared with prior art, the beneficial effect that the present invention reaches is: be provided with feed liquor runner along drill lip, return liquid runner, cooling fluid circulates between feed liquor runner and time liquid runner, does not directly contact with workpiece, avoids polluting or corrosion workpiece; Feed liquor runner, time liquid runner are offered along the drill lip hand of spiral, can ensure the cooling fluid flow process of the most enough length, cooling fluid is made full use of, reach good cooling effect; Be provided with the elements such as control unit, frequency converter, the first temperature sensor and the second temperature sensor, temperature can be realized and automatically measure, automatically control.
