Background
The circular nose knife is a knife with the length of the arc part being larger than 1/4 circle. The round nose knife combines the advantages of the end milling cutter and the ball knife, a small R angle is used at the edge, but the cutting function of the bottom surface cutting edge is reserved, which is equivalent to adding the R angle smaller than the radius of the cutter to the end milling cutter, when the round nose knife mills a workpiece, four points can all keep a certain cutting speed, the quality of a processing surface is better than that of the ball knife, and the bottom surface milling capability of the end milling cutter is reserved, and the relatively rapid milling speed can be achieved when the relatively flat surface is processed, so the round nose knife is widely used in the field of mechanical processing.
However, when a metal part is cut by the circular nose tool, a large amount of flying chips are generated, and the flying chips often splash onto the body of an operator to cause injury to the body of the operator, so that there is an urgent need for a circular nose tool capable of preventing the flying chips from splashing to protect the operator from injury.

In order to solve the technical problems, the safety protection integrated circular nose knife comprises a knife handle and a milling cutter head arranged at the front end of the knife handle, wherein the knife handle and the milling cutter head are integrally manufactured, the safety protection integrated circular nose knife further comprises an arc-shaped protection cover, a sleeve, a sliding rod, a sliding sleeve and a spring, the sleeve is sleeved on the knife handle, the sliding sleeve is in a barrel shape and is fixedly arranged on the outer wall surface of the sleeve along the axial direction of the sleeve, the spring is arranged at the bottom of the sliding sleeve, one end of the sliding rod is fixedly connected with the arc-shaped protection cover, the other end of the sliding rod is propped against the spring, the rod body of the sliding rod is in sliding fit with the sliding sleeve, and the arc-shaped protection cover covers the milling cutter head.
As a preferred embodiment of the utility model, four cooling liquid tanks are axially arranged on the outer wall surface of the cutter handle, and the cooling liquid tanks are communicated with the cutting edge grooves of the milling cutter head.
As a preferred embodiment of the utility model, an annular groove is arranged on the outer wall surface of the front end of the tool handle, a screw hole is arranged on the sleeve, and the sleeve is fixedly arranged on the tool handle through a locking screw screwed into the screw hole and the annular groove.
As a preferred implementation mode of the utility model, the number of the sliding rod, the sliding sleeve and the spring is two, and the sliding rod, the sliding sleeve and the spring are symmetrically and fixedly arranged on the outer wall surface of the sleeve along the axial direction of the sleeve.
After the structure is adopted, the utility model has the following beneficial effects:
the circular nose knife is provided with an arc-shaped protective cover, a sleeve, a slide bar, a slide sleeve and a spring, wherein the sleeve is sleeved on a knife handle, the slide sleeve is in a barrel shape and is fixedly arranged on the outer wall surface of the sleeve along the axial direction of the sleeve, the spring is arranged at the bottom of the slide sleeve, one end of the slide bar is fixedly connected with the arc-shaped protective cover, the other end of the slide bar abuts against the spring, the rod body of the slide bar is in sliding fit with the slide sleeve, and the arc-shaped protective cover covers a milling cutter head. During operation, the arc-shaped protective cover can effectively shield and protect flying chips generated by cutting and machining of metal workpieces, so that the flying chips are prevented from splashing to cause injury to operators, and the safety of the circular nose knife during use is improved.
The utility model is provided with four cooling liquid tanks along the axial direction on the outer wall surface of the cutter handle, and the cooling liquid tanks are communicated with the cutting edge groove of the milling cutter head. Therefore, in the working process, on one hand, the cooling of the cutter during high-speed cutting can be assisted, so that the service life of the cutter is prolonged, and on the other hand, cooling liquid flowing along the cooling liquid groove can be matched with the arc-shaped protective cover to press flying chips generated by cutting the cutter in the arc-shaped protective cover.
