It is above-mentioned dismounting drill bit with drill bit.
Above-mentioned dismounting drill bit is connected use with drilling machine component, improves the versatility of the dismounting drill bit.In addition, match somebody with somebody
The positioning tool using part to be demolished is closed, drastically increases the efficiency of dismantlement work.
The specific embodiment of the dismounting drill bit of the utility model is as follows：
First, it is improved based on universal twist drill, ensures that the pedestal 40 for being fabricated to dismounting drill bit can be with various brill
Bed connection improves the versatility of dismounting drill bit；
Secondly, according to the big spiral bit such as the oil sealing cap outer diameter of part to be demolished, selection, further according to the press-in of oil sealing cap
Depth in the head outer ring of fried dough twist drill bit, opens the step of even depth processed, the method is mainly to control to pierce depth, avoids boring
Enter too deep other fan parts of damage bearing or shaft etc..
Finally, fluted drill bit central is subjected to hollow out, hollow out internal diameter is equal to outer diameter of step in oil sealing cap, hollow out spiral shell in pairs
Structure is revolved, double-spiral structure forms the accommodating chamber of dismounting drill bit, and accommodating chamber is beneficial to follow-up interim storage chip.
The essential characteristic of dismounting drill bit is as described above, by this dismounting drill bit, then aids in determining with part to be demolished
Position frock, is pierced with center position, pierces the step 30 that depth ends in dismounting drill bit, in removal oil sealing cap interference
After mating part, drill bit is slowly lifted, step can be acted on due to the centrifugal force of rotation in oil sealing cap, from screw-in dismounting drill bit
At accommodating chamber, after continuously disassembling several oil sealing caps, choose step defective material in oil sealing cap, Ke Yiji from gap between spiral with needle bar
It is continuous to carry out repeating to disassemble.The dismounting of the utility model can effectively improve the work efficiency of dismantlement work with drill bit, save whole
Chance error damages expense, and reduces the labor intensity of employee.
It can be seen from the above description that the above embodiments of the present invention achieve the following technical effects：This reality
A kind of dismounting drill bit is provided with new and using its drilling machine component.Dismounting includes drill body, cutting portion, limit with drill bit
Position portion and pedestal.Cutting portion is arranged on drill body and for cutting part to be demolished；Limiting section be arranged on drill body and
To limit position of the dismounting drill bit compared with part to be demolished between cutting portion, wherein, drill body have accommodating chamber and with
The opening of accommodating chamber connection, accommodating chamber are used to accommodate at least a portion part to be demolished.Due between cutting portion and drill body
There are limiting section, so as to which in the dismounting drill bit of use the utility model, limiting section can effectively limit cutting portion entrance and treat
The depth of cutting part, and then avoid when dismantling part to be demolished, because cutting portion gos deep into damaging not when component to be cut is excessive
Need the other component dismantled.Further, the chip under being cut enters accommodating chamber by the utensil receiving opening of drill body, makes dismounting
Work can be carried out continuously, and avoid progress chip cleaning after the completion of cutting every time, be improved work efficiency.Therefore, pass through
Above-mentioned setting simplifies the disassembly process of oil sealing cap, avoids complete machine damage after dismantling and scraps, has saved complete machine and accidentally injured expense,
The work efficiency disassembled is improved, and reduces the labor intensity of worker.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, for this
For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model
