Technical Field

The utility model relates to the technical field of machining, in particular to a multifunctional composite cutter.

Background

A tool is a tool used for cutting machining in machine manufacturing, and is also called a cutting tool.

The traditional machining tool has the following defects: 1. the function is single, the special cutter is special, different cutters are used in different processing procedures, and the processing cost is greatly increased; 2. during processing, the special cutter is special, so that the cutter needs to be changed in different processing procedures, the processing time is greatly increased, and the processing efficiency is influenced; 3. the more cutters occupy more machine tool cutter stock clamping positions; in order to solve the problems, a composite drilling, boring and chamfering integrated cutter is specially designed, and aims to solve the problems.

SUMMERY OF THE UTILITY MODEL

The present invention is directed to a multifunctional compound cutting tool to solve the above problems.

In order to achieve the purpose, the utility model provides the following technical scheme: a multi-function composite cutting tool comprising: rough drill edge, reverse chamfer sword, chip groove and handle of a knife, handle of a knife one end has rough drill edge through processing, the processing of rough drill edge below one side has the bore hole sword, processing has reverse chamfer sword between rough drill edge one end and the handle of a knife, the processing of rough drill edge profile position has the chip groove, processing has the vacancy of avoiding between chip groove afterbody and the handle of a knife.

Furthermore, a chamfer is processed at the joint of the boring blade and the end face of the cutter and is used for chamfering a boring opening or removing burrs.

Furthermore, the boring blade protrudes out of the rough drilling blade, and the rough drilling blade is used for roughly drilling holes and leaving allowance.

Further, the boring blade is used for carrying out inner hole fine boring on the rough machining hole and machining an inner hole profiled groove.

Further, the reverse chamfer edge is used for reversing the orifice and removing burrs.

Compared with the prior art, the utility model has the beneficial effects that:

according to the utility model, through the arrangement of the rough drilling edge, the boring edge and the reverse chamfering edge, when the multifunctional composite cutter is used, rough machining and drilling are carried out on a hole through the rough drilling edge, allowance is reserved, inner hole fine boring is carried out on the rough machining hole through the boring edge in place, the diameter of the inner hole and the roughness of the inner hole or the machining of an inner hole special-shaped groove are ensured, meanwhile, the boring edge can also be used for boring an orifice chamfer or deburring, the reverse chamfering edge is used for chamfering or deburring the reverse orifice, and the composite cutter integrates rough machining of the inner hole, a finish machining inner hole or special-shaped groove, and chamfers of front and rear orifices into a whole; the traditional cutter generally needs a rough drill, a fine machining and a chamfer cutter to process the product; the machining requirement can be met only by one cutter, the machining cost can be greatly saved, the cutter changing time is saved, the machining efficiency is increased, and the cutter clamping position of a machine tool cutter library cannot be occupied too much.
