The utility model has the advantages of reasonable and simple structure, the simple operation is installed the handle of a knife on the drilling machine, processes the part through the rotation of drilling machine control handle of a knife because the cutting edge sets the echelonment to can directly drill out the hole of many steps on the part, the efficiency of great improvement processing avoids the error of bringing of tool changing many times simultaneously, improves the accurate nature of processing.
Description
Technical Field
The utility model relates to a reaming technology technical field, concretely relates to multiple step gang tool.
Background
In industrial production, generally, a hole machining operation is required for a workpiece, and conventional hole machining methods include: drilling, reaming, boring, turning, grinding, and the like. When a workpiece needs to be subjected to multi-step hole machining, cutters with different diameters need to be used for machining, machining efficiency is greatly reduced, due to the fact that a plurality of cutters are used, repeated positioning is needed for many times, errors can be brought, and machining errors are greatly improved.
The above problems are problems that the art needs to solve.
Disclosure of Invention
The to-be-solved technical problem of the utility model is to provide a multiple step gang tool to can once only process the hole of multiple step, the efficiency of great improvement production improves the precision of processing simultaneously.
In order to solve the technical problem, the utility model provides a scheme is: the multi-step compound cutter comprises a cutter handle, wherein a cutter body is arranged at the tail of the cutter handle, a step-shaped cutting edge is arranged on the cutter body, blades are arranged on the step surface of the cutting edge, and a drill bit is arranged at the bottom of the cutter body.
As a further improvement, the blade is made of a novel polycrystalline diamond material.
As a further improvement, the knife handle and the knife body are made by an integrated technology.
As a further improvement of the present invention, the blade is connected to the cutting edge by welding.
As a further improvement of the utility model, the cutting edge is provided with a chamfer.
The utility model has the advantages that:
the utility model has the advantages of reasonable and simple structure, the simple operation is installed the handle of a knife on the drilling machine, processes the part through the rotation of drilling machine control handle of a knife because the cutting edge sets the echelonment to can directly drill out the hole of many steps on the part, the efficiency of great improvement processing avoids the error of bringing of tool changing many times simultaneously, improves the accurate nature of processing.
Drawings
Fig. 1 is a front view of the present invention.
Reference numerals: 1. a knife handle; 2. a cutter body; 3. a blade; 4. a blade; 5. a drill bit; 6. and (6) chamfering.
Detailed Description
The present invention is further described with reference to the following drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.
Referring to fig. 1, for the utility model discloses an embodiment, including handle of a knife 1, 1 afterbody of handle of a knife is provided with cutter body 2, be provided with the cutting edge 3 of echelonment on the cutter body 2, all be provided with blade 4 on the ladder face of cutting edge 3, 2 bottoms of cutter body are provided with drill bit 5, install handle of a knife 1 on the drilling machine, fix the part in the below of drill bit 5 simultaneously, punch the processing through drill bit 5 to the part, blade 4 drills to the part, because cutting edge 3 presents the echelonment, thereby can directly once only process the hole of many steps on the part, the efficiency of great improvement production, improve the precision of processing simultaneously.
In this embodiment, blade 4 adopts novel polycrystalline diamond material to make, can improve blade 4's life. The knife handle 1 and the knife body 2 are manufactured by adopting an integrated technology, so that the connection strength of the knife handle 1 and the knife body 2 can be improved, and the fracture in use is avoided, thereby ensuring the safety in use. The blade 4 and the blade 3 are connected by welding, so that the firmness of connection between the blade 4 and the blade 3 can be improved. The cutting edge 3 is provided with a chamfer 6, which can chamfer multi-step holes.
The above-mentioned embodiments are merely preferred embodiments for fully illustrating the present invention, and the scope of the present invention is not limited thereto. Equivalent substitutes or changes made by the technical personnel in the technical field on the basis of the utility model are all within the protection scope of the utility model. The protection scope of the present invention is subject to the claims.
