Abstract
The utility model relates to a drill chuck which comprises a drill chuck body, a flange and a taper shank. The flange is fixedly sleeved on the outer diameter of the drill chuck body through a bolt, a through hole is arranged on the excircle of the flange, a locking sleeve is arranged inside the drill chuck body, one end of the taper shank is connected into the locking sleeve, and a mounting hole is arranged in the taper shank. The flange is sleeved on the drill chuck body, the through hole is arranged on the excircle of the flange, and a straight spanner is used to be inserted into the through hole to wrench the drill chuck body to realize quick clamping or loosing of the drill chuck, so that clamping force of a drill bit is improved; the mounting hole is arranged in the taper shank, swaying of the drill bit can be effectively controlled by inserting a handle portion of the drill bit into the mounting hole, centering is effective, and production quality and efficiency are improved.
Description
Technical field
The utility model relates to a kind of mechanical clamp for shaft instruments such as clamping drilling bit, screw taps, is specifically related to a kind of drill chuck of clamping drilling bit.
Background technology
Drill chuck is used for clamping the various throws such as drill bit, screw tap as a kind of throw clamp structure, uses very extensive.By manual rotation drill chuck shell, can unclamp or clamp throw.The drill chuck of prior art often makes drill slipping because of insufficient clamping force with bevel gear spanner clamping drill bit the time; As the groove tooth of the drill chuck shell that pounds with a hammer, make its clamping or unclamp, often use will affect the precision of drill chuck; When the drill bit below the clamping Ф 10mm, often because stretching out the oversize drill bit that causes, drill bit swings, and the inaccurate hole drill that makes of feeling relieved is inclined to one side.
The utility model content
The utility model purpose is the drill chuck that provides a kind of precise structure compact, easy to assembly, simple to operate in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of drill chuck comprises drill chuck body, flange, taper shank; Described flange is bolted and is socketed on this body diameter of drill chuck; Described flange excircle is provided with through hole; The drill chuck body interior is provided with lock sleeve; Described taper shank one end is connected in the lock sleeve; Be provided with installing hole in the described taper shank.
Because the utilization of technique scheme, the utility model compared with prior art has following advantages:
A kind of drill chuck of the utility model scheme, by being socketed a flange at the drill chuck body, be provided with through hole at flange excircle, then utilize straight spanner to insert to pull in the through hole drill chuck body to realize the drill chuck Quick-clamped or unclamp, improved the clamping force to drill bit; By in taper shank, being provided with installing hole, allow drill handle part insert in the installing hole, can effectively control the swing of drill bit, centering has better improved the quality of production and efficient.
