Abstract

The utility model 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 has a cylindrical structure, a cutter head is fixedly arranged at one end of the cutter handle, and an adjustable antiskid bolt matched with the three jaw chuck is arranged on the cutter handle. The novel milling cutter has a reasonable structure, after the cutter handle of the milling cutter is clamped on the three jaw chuck, an eccentric block contacts the side edge of the three jaw chuck by rotating the antiskid bolt, so that the cutter handle and the three jaw chuck are tightly locked and no slipping space is left, impact damage caused by slipping of the cutter handle is effectively avoided, and the use safety of the milling cutter is improved.

Description

A kind of novel milling cutter

Technical field

The utility model 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 for manufacturing procedures such as the cutting of piece surface, groove milling, quit a post and thus leave it vacants.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 the generation impression to 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.

Utility model content

The purpose of this utility model is for the defect of prior art and deficiency, and 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 utility model is by the following technical solutions:

The novel milling cutter of one described in the utility model, 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.

The utility model beneficial effect is: the utility model 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.

Accompanying drawing explanation

Fig. 1 is the structural representation of facing of the present utility model;

Fig. 2 is side-looking structural representation of the present utility model.

In figure:

1, handle of a knife; 2, cutter head; 3, scroll chuck; 4, blade;

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

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is further described.

The novel milling cutter of one described in the utility model, 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 preferred embodiments of the present utility model, and the equivalence of doing according to structure, feature and principle described in the utility model patent claim therefore all changes or modifies, and is included in the utility model patent claim.
