Description
Technical field
The utility model belongs to bit technique field, is specifically related to a kind of drill bit for balance shaft housing boring.
Background technology
Hole on automobile balance axle housing is more, especially 8-∮ 26 hole is given prominence to, in prior art, this some holes mainly completes boring with common alloy bit, however due to the hole on balance shaft housing darker, be easier to make alloy bit consumption in process, service life is affected to a certain extent, and the knife bar of the alloy bit of prior art and drill bit are wholely set, and is not easy upon wear to change, affect its service efficiency to a certain extent, be difficult to the demand meeting market.
Summary of the invention
It is simple that the purpose of this utility model is to provide a kind of structure, the good and drill bit of holing for balance shaft housing be convenient for changing of stability in use.
The technical scheme realizing the utility model object is a kind of drill bit for balance shaft housing boring, comprise cutter head and knife bar, one end on described knife bar is provided with holddown groove, described knife bar is connected with rig by holddown groove end, center mounting hole is provided with at the other end of described knife bar, the installation matched with described center mounting hole is provided with protruding in one end of described cutter head, clamping caliper is provided with in described center mounting hole, described knife bar is provided with control poke rod, the outside of described control poke rod and the outer surface of knife bar are on the same face, small cylinder is provided with in described center mounting hole, the piston axle of described small cylinder is connected with described clamping caliper and controls clamping caliper and clamps or loosen, described control wave lever is connected with the control end of described small cylinder, described installation projection is provided with fixed groove, described clamping caliper is movable clamping in fixed groove.
Described center mounting hole is little being obliquely installed in large inner end, outer end, and described projection of installing is the round table-like setting matched with described center mounting hole.
Be equipped with dust lead at the outer surface of described cutter head and knife bar and revolve tooth.
Sealant is provided with between described control wave lever and knife bar.
The utility model has positive effect: structure of the present utility model is simple, the cutter head of drill bit and knife bar separate type are arranged, when in long-time use during tool bit abrasion, only need in time the tool bit part of more bit change, easy to use, can effective saving resource, improve to a certain extent and change efficiency, stability in use is better, improves processing work efficiency to a certain extent, applicability is strong, and practicality is good.
