Abstract
A high-performance antiskid shank shrinkage drill bit comprises a drill bit body and a clamping device. The drill bit body is a twist bit. Cutting edges are arranged on the drill bit body and intersect with one another. The clamping device is arranged around the drill bit body and is a jaw, and the jaw is a four-foot jaw and is provided with fixed pieces. The fixed pieces are rectangular fixed blocks. Absorption pieces are arranged on the rectangular fixed blocks and distributed on the jaw. The clamping device is arranged on the drill bit, and therefore machining of the drill bit can be facilitated, and the situation that the drill bit skids on a workpiece, and consequently the quality of the outer surface of the workpiece is influenced can be avoided; meanwhile, the locating effect of the drill bit can be improved, the drill bit can be located conveniently by itself, and the work efficiency of the drill bit is improved; and a sheath is arranged on a connecting shank and can protect the connecting shank, and the connecting shank is prevented from being rusted.
Description
Technical field
The present invention relates to a kind of drill bit, be specifically related to the anti-skidding contracting handle of a kind of high-performance drill bit.
Background technology
Traditional drill bit when in use, can not own on workpiece, position, often need to just can position by operating personnel, increase operating personnel's work load, reduce operating personnel's operating efficiency, also have part drill bit easily to skid when in use, especially when running into the larger workpiece of intensity, can leave cut at surface of the work once skid, affect the finish of surface of the work, make workpiece in following process, also will carry out the polishing of outer surface, increase the manufacturing cost of workpiece, the large heavy discount of serviceability of drill bit, the result of use of drill bit is declined.
Summary of the invention
The object of this invention is to provide one and grasp firmly, the anti-skidding contracting handle of a kind of high-performance drill bit that is difficult for skidding.
Technical scheme of the present invention is: the anti-skidding contracting handle of a kind of high-performance drill bit, comprise drill bit and clamping device, described drill bit is spiral bit, described drill bit is provided with cutting edge, described cutting edge intersects mutually, described drill bit is provided with clamping device around, described clamping device is claw, described claw is four pin claws, described claw is provided with fixture, described fixture is rectangle fixed block, and described rectangle fixed block is provided with adsorption piece, and described adsorption piece is distributed in the upper of claw.
After described drill bit, be provided with connection handle; described connection handle is hexagonal shape; described connection handle is provided with sheath; described sheath is thin stainless steel; between described sheath and connection handle for being flexibly connected; described jacket inner wall is provided with guard member, and described guard member is rubber layer, and the thickness of described rubber layer is 0.5-0.8cm.
Described connection handle afterbody is provided with sleeve assembly parts, described sleeve assembly parts are flexible stainless steel substrates, described sleeve assembly parts are arranged on the both sides of connection handle, described sleeve assembly parts have elastic device, described elastic device is annulus stage clip, and described elastic device and sleeve assembly parts and connection handle interconnect.
Advantage of the present invention is: on drill bit, be provided with clamping device, can facilitate the processing of drill bit, prevent that drill bit from skidding on workpiece, affect the quality of outer surface of workpiece, also can promote the locating effect of drill bit simultaneously, facilitate drill bit to carry out oneself location, improve the operating efficiency of drill bit, on connection handle, be provided with sheath, can protect connection handle, prevent that corrosion from appearring in connection handle, adopt bascule to make sheath more convenient to use, in drill bit work, sheath can be extractd, in the time that drill bit is idle, sheath can be sleeved on connection handle, prevent that connection handle from breaking, affect the result of use of drill bit, be provided with sleeve assembly parts at connection handle afterbody, can facilitate being connected of connection handle and drilling machine sleeve, make both connections more firm, drill bit there will not be large area to rock.
