Description
Technical Field
The utility model belongs to the technical field of machining, and particularly relates to an efficient and convenient drill bit for machining.
Background
When the existing drill bit drills holes, scrap iron flies everywhere, and even flies into eyes of workers when the existing drill bit is serious, so that serious consequences are caused, and in addition, the ground of a factory is unsanitary.
Disclosure of Invention
The utility model aims to overcome the defects in the prior art and provides an efficient and convenient drilling bit for machining.
In order to achieve the purpose, the utility model adopts the following technical scheme:
a high-efficiency portable drill bit for machining comprises a body, a connector positioned at the upper end of the body and used for being connected with a motor, and a chip collecting cover sleeved on the body; the body comprises a smooth section with the upper end connected with the connector and a thread section positioned at the lower end of the smooth section; the scrap collecting cover comprises a guide sleeve sleeved on the smooth section and a cover body in a round table shape; the upper end of the cover body is a small-diameter end, the upper end of the cover body is connected with the guide sleeve, the lower edge of the cover body is provided with an annular magnet, and the lower side of the connector is provided with a magnetic block for adsorbing the guide sleeve; when the magnetic block is matched with the guide sleeve, the lower end of the body is lower than the annular magnet.
Preferably, an annular cavity is arranged in the guide sleeve, an annular groove is formed in the inner side of the guide sleeve, a limiting groove communicated with the annular cavity is formed in the bottom of the annular groove, balls are arranged in the limiting groove and abut against the smooth section, lubricating oil is arranged in the annular cavity, and an oil injection nozzle is arranged on the guide sleeve.
Preferably, the end of the oil nozzle far away from the guide sleeve inclines upwards.
The utility model has the beneficial effects that: iron fillings are concentrated in the collection bits cover when beginning to drill, can not fly in disorder, and the cover body adopts transparent material, is convenient for observe, and when the pivoted, the ball plays the effect that reduces friction power, in addition, can scribble the lubricating oil in the annular cavity in the pivoted on smooth section, further reduces friction power, after having drilled, adsorbs the uide bushing on the magnetic path again, then the clearance cover iron fillings under the body can.
