Abstract
The utility model discloses a composite expansion reamer, and belongs to the technical field of reamers. The main body of the composite expansion reamer is a tool body, wherein the tool body is provided with a tool bit; the tool bit comprises a first tool bit and a second tool bit; blades are arranged on the first tool bit and the second tool bit; the outer side faces of the blades are inclined surfaces; each of the inclination angles of the outer side faces of the blades are 8 degrees. The composite expansion reamer is simple in structure, an inner hole and an outer hole can be machined at the same time, producers are reduced, materials and labor force are saved, and the yield is increased within equal time.
Description
Technical field:
The utility model relates to reamer technical field, relates in particular to a kind of compound reamer.
Background technology:
In machine-building, need to punch, and the required precision of punching is high.The operation of punching is more, boring, reaming, fraising etc.While sometimes needing coaxial Da Liangge hole, former is that two reamers are processed respectively Liang Ge hole two operations with cutter, wastes material, manpower, has also wasted the time.
Utility model content:
Technical problem to be solved in the utility model is to overcome the defect of prior art, provide a kind of fast, reduce operation, time-saving compound reamer.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of compound reamer, it is characterized in that: its main body is cutter hub, on cutter hub, be provided with cutter head, cutter head comprises the first cutter head and the second cutter head, on the first cutter head and the second cutter head, blade is installed, and the lateral surface of blade is inclined plane, the angle of inclination of blade lateral surface is 8 °, prevent that blade from fractureing when rotation punching, and reduce the side of blade and the contact-making surface between device, reduced crude degree and improved precision.
Described the first cutter head is coaxial with the second cutter head, and the diameter of the first cutter head is greater than the second tool bit diameter.
Described the first cutter head, the second cutter head and cutter hub one are cast.
The beneficial effects of the utility model: the utility model is simple in structure can be processed inside and outside Liang Ge hole simultaneously, have reduced operation, have saved material, manpower, within the equal time, have improved output.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the second cutter head A-A face sectional view in Fig. 1;
Fig. 3 is the first cutter head A-A face sectional view in Fig. 1.
The specific embodiment:
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of compound reamer, its main body is cutter hub 1, on cutter hub 1, is provided with cutter head, and cutter head comprises the first cutter head 2 and the second cutter head 3, on the first cutter head 2 and the second cutter head 3, blade 4 is installed, the lateral surface 5 of blade is inclined plane, and the angle of inclination of blade 4 lateral surfaces 5 is 8 °, prevents that blade 4 from fractureing when rotation punching, and reduce the side of blade 4 and the contact-making surface between device, reduce crude degree and improved precision.The first cutter head 2 is coaxial with the second cutter head 3, and the diameter of the first cutter head 2 is greater than the second cutter head 3 diameters.The first cutter head 2, the second cutter head 3 are cast with cutter hub 1 one.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
