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 the circular nose knife is used for cutting metal parts, a large amount of cut flying chips are generated, the flying chips are often splashed onto an operator, and the operator is injured, while the existing protective device for the circular nose knife is only provided with a baffle plate above the circular nose knife to shield the flying chips, in the actual use process, the flying chips above the circular nose knife can be blocked only, the flying chips in other directions of the circular nose knife can not be blocked, the phenomenon that the baffle plate loosens and slides down can occur, the protectiveness is reduced, meanwhile, the injury to the operator is possibly increased, and therefore, the circular nose knife capable of comprehensively preventing the flying chips from splashing is needed to protect the operator from injury.
Disclosure of Invention
The utility model aims to solve the technical problem of overcoming the defects of the prior art and providing the circular nose knife with the safety protection cover, which has the advantages of simple structure, and capability of comprehensively preventing flying scraps from splashing on an operator and ensuring that the operator is not injured.
In order to solve the technical problems, the circular nose knife with the safety protection cover 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 circular nose knife with the safety protection cover further comprises an umbrella-shaped protection cover, a sleeve and a spring, the sleeve is sleeved on the knife handle, the umbrella-shaped protection cover comprises at least three supporting rods, the upper end of each supporting rod is rotatably connected with the outer wall of the sleeve, the lower end of each supporting rod is obliquely arranged away from the cutter head, the at least three supporting rods are connected through flexible materials, the spring is arranged between the supporting rods and the sleeve, one end of the spring is fixedly connected with the supporting rods, the other end of the spring is fixedly connected with the sleeve, and the umbrella-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.
After the structure is adopted, the utility model has the following beneficial effects:
the circular nose knife is provided with an umbrella-shaped protective cover, a sleeve and a spring, wherein the sleeve is sleeved on a knife handle, the umbrella-shaped protective cover comprises at least three supporting rods, the upper end of each supporting rod is connected with the outer wall of the sleeve in a rotating way, the lower end of each supporting rod is arranged away from the knife head in an inclined way, the at least three supporting rods are connected through flexible materials, the spring is arranged between the supporting rods and the sleeve, one end of the spring is fixedly connected with the supporting rods, the other end of the spring is fixedly connected with the sleeve, and the umbrella-shaped protective cover covers the milling knife head. During operation, the expansion action or the contraction action of the spring is matched with the expansion action or the contraction action of the umbrella-shaped protective cover, the umbrella-shaped protective cover can effectively fully shield and protect flying scraps generated by cutting of metal workpieces, the flying scraps 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, the cooling liquid flowing along the cooling liquid groove can be matched with the umbrella-shaped protective cover to press flying chips generated by cutting the cutter into the umbrella-shaped protective cover.
