Description
Technical Field
The utility model relates to a dyeing field, in particular to honing cutter.
Background
In the field of aerospace high-end manufacturing industry, the requirements of novel products on processing precision and surface quality are higher and higher, the size of the products is larger and larger, and the structures of the products are more and more complex; the improvement of the index requirements of the products such as performance, size, appearance and the like breaks through the processing limit of original equipment and tools, and provides higher requirements for the processing equipment, the processing precision and the like of the products.
In the existing machining process, the hole is drilled firstly, and then the hole is honed, so that the accuracy in the hole is increased, the hole can be machined completely by two steps, one more step is needed, the machining time is increased invisibly, the machining efficiency is reduced, and a solution is needed to be provided for the problems.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a honing cutter.
The above technical purpose of the present invention can be achieved by the following technical solutions:
the utility model provides a honing cutter, includes the cutter arbor, the cutter arbor bottom is provided with the handle of a knife, the cutter arbor top is provided with the drill bit, two spiral chip grooves have been seted up on the cutter arbor, set up the mounting groove between two helicla flutes on the cutter arbor, be provided with the whetstone seat in the mounting groove, install the honing whetstone on the whetstone seat.
Adopt above-mentioned technical scheme, the drill bit punches to the work piece, and the iron fillings that cut off when punching are discharged from the chip groove, and when the drill bit continued to stretch into downwards, the honing oilstone on the oilstone seat honed the pore wall, when the honing oilstone was changed, can change the honing oilstone through mounting groove and oilstone seat.
Preferably, the two top ends of the drill bit intersect with the axis of the base body and are inclined towards the two sides of the base body, and the intersecting angle of the top ends is 118 degrees.
By adopting the technical scheme, a hole with a hole bottom of 120 degrees can be drilled by the 118-degree cutting edge, the 118-degree drill bit is good in stability, the length of the cutter band is long, and the heat dissipation performance is good.
Preferably, both sides of the honing oilstone are formed with cutting corners.
By adopting the technical scheme, the formed cutting corner is convenient for honing the hole wall, and the processing efficiency is convenient to improve.
Preferably, the knife handle is sleeved with the connecting seat.
By adopting the technical scheme, the connecting seat is convenient for connecting the tool shank to the main shaft.
Preferably, one end of the connecting seat, which is far away from the knife handle, is provided with a taper shank.
By adopting the technical scheme, the taper shank is convenient for the connecting seat to be fixed on the main shaft.
Preferably, the connecting seat is symmetrically provided with rotating grooves on the side surface.
Adopt above-mentioned technical scheme, be fixed with the briquetting under the main shaft, the briquetting is installed and is rotated the inslot, and when the main shaft rotated, the briquetting drove the connecting seat rotation through rotating the groove.
