Abstract

The invention relates to the technical field of hardware cutters, and particularly relates to a novel milling cutter. The novel milling cutter comprises a cutter handle fixed on a three-jaw chuck, wherein the cutter handle is of a cylindrical structure, one end of the cutter handle is fixedly provided with a cutter head, and the cutter handle is provided with an adjustable antiskid bolt matched with the three-jaw chuck. The novel milling cutter provided by the invention has the advantages that the structure is reasonable; the cutter handle of the milling cutter is clamped on the three-jaw chuck, then the antiskid bolt is rotated so as to enable an eccentric block to push against the side edge of a clamping jaw, a slipping space between the cutter handle and the clamping jaw is locked, the impact damage caused by the cutter handle in slipping is effectively avoided, and thus the using security of the milling cutter is improved.

Description

A kind of novel milling cutter

Technical field

The present invention relates to hardware and cutting-tools technical field, particularly a kind of novel milling cutter.

Background technology

The hardware and cutting-tools using in machining comprises lathe tool, milling cutter, planing tool, fluted drill etc., and milling cutter is wherein the manufacturing procedures such as cutting for piece surface, groove milling, quit a post and thus leave it vacant.Common milling cutter comprises handle of a knife and cutter head, and handle of a knife is fixed on the scroll chuck of lathe and by main shaft driven rotary conventionally, and the some blades on cutter head cut part.In process, milling cutter is cut the effect of reaction force, and milling cutter easily skids in chuck.For avoiding this problem, operative employee understands excessive screwing chuck to increase the clamping dynamics of chuck conventionally, until sensation is stubborn motionless.But excessive clamping can cause the gap of chuck to increase, and to the generation impression on handle of a knife surface and then reduce milling cutter service life; Also can make the pivot of milling cutter produce skew, slightly not note damaging cutter head, part, reduce production efficiency.

Summary of the invention

The object of the invention is to defect and deficiency for prior art, a kind of rational in infrastructure, easy to use, the novel milling cutter that can effectively avoid the applicable groove milling of skidding is provided.

For achieving the above object, the present invention is by the following technical solutions:

A kind of novel milling cutter of the present invention, comprises the handle of a knife being fixed on scroll chuck, and the cylindrical structure of described handle of a knife, is fixed with cutter head on one end of handle of a knife; Handle of a knife is provided with the adjustable anti-skid bolt coordinating with scroll chuck.

Further, described adjustable anti-skid bolt comprises and presses closer screw, in the outer rim of handle of a knife, has screwed hole, presses closer screw one end and screws in screwed hole, presses closer the screw other end and is provided with eccentric block.

Further, described screwed hole is located at the junction of handle of a knife and scroll chuck.

Further, in described cutter head outer rim, be welded with some blades, the outside cutting edge of blade and the rotation centerline of cutter head are angle setting, and the base cutting edge of blade and head base surface are 15 degree angle settings.

Beneficial effect of the present invention is: the present invention is rational in infrastructure, after the handle of a knife of milling cutter clamps on scroll chuck, rotation anti-skid bolt makes the side of eccentric block conflict claw, and then the space of skidding between locked handle of a knife and claw, the impact injury that can effectively avoid handle of a knife to skid causing, improves the security that milling cutter uses.

11, screw hole; 12, press closer screw; 13, eccentric block.

The specific embodiment

Below in conjunction with accompanying drawing, the present invention is further illustrated.

A kind of novel milling cutter of the present invention, comprises the handle of a knife 1 being fixed on scroll chuck 3, and the cylindrical structure of described handle of a knife 1, is fixed with cutter head 2 on one end of handle of a knife 1, is welded with some blades 4 in cutter head 2 outer rims; The outside cutting edge of blade 4 and the rotation centerline of cutter head 2 are angle setting, and the base cutting edge of blade 4 and cutter head 2 bottom surfaces are 15 degree angle settings; When handle of a knife 1 rotates with scroll chuck 3, be with dynamic cutter head 2 integral-rotations and then cutting workpiece, blade 4 rotations are trapezoidal track, and then carry out dovetail groove milling processing.

Above-mentioned handle of a knife 1 is provided with the adjustable anti-skid bolt coordinating with scroll chuck 3, adjustable anti-skid bolt comprises and presses closer screw 12, in the outer rim of handle of a knife 1, have screwed hole 11, described screwed hole 11 is located at the junction of handle of a knife 1 and scroll chuck 3, press closer screw 12 one end and screw in screwed hole 11, press closer screw 12 other ends and be provided with eccentric block 13; Handle of a knife 1 upper end is placed in scroll chuck 3 and by its clamping, adjustable anti-skid bolt is corresponding wherein direction of rotation one side of a claw of scroll chuck 3 that is placed in, and then rotate adjustable anti-skid bolt eccentric block 13 and claw side are conflicted, make milling cutter grab chuck 3 one rotations man-hour and three and the deflection of not skidding adding, the space of skidding between locked handle of a knife 1 and claw, the impact injury of avoiding handle of a knife to skid causing, improves the security that milling cutter uses.

The above is only better embodiment of the present invention, and the equivalence of doing according to structure, feature and principle described in patent claim of the present invention therefore all changes or modifies, and is included in patent claim of the present invention.
