Abstract
A stepped reamer consists of a working part and a handle part, wherein a cutting part of the working part comprises more than one bits that are connected in sequence and are different in diameter. With reamer bits of various diameters combined on one reamer, the processing time is greatly reduced, the processing accuracy is obviously improved and the processing cost is decreased.
Description
Technical field
The utility model relates to mechanical field, is specifically related to a kind of Stepped Reamers.
Background technology
Reamer is commonly used to processing column shape hole, also can be used to process bellmouth sometimes, and the reamer of processing bellmouth is a taper reamer.Reamer structure major part is made up of working portion and shank.Reamer is made up of working portion 1, neck 2 and shank 3.Working portion 1 is divided into cutting tip 11 and calibration (smoothing) 12 parts again, and calibrated section 12 diameters have back draught, are used for calibration.Shank then is used for by the anchor clamps clamping branch of staight shank and taper shank being arranged.The cutting tip 11 of existing reamer has only a kind of cutting diameter, promptly only is provided with a cutter head, when required precision is high, need change the reamer of various cutter heads by operation, and operating efficiency efficient and machining accuracy are not high.Improve the structure of reamer, imperative.
Summary of the invention
The purpose of this utility model is, overcomes the defective of prior art, provides a kind of machining accuracy the high and high reamer of efficient.
The technical scheme that realizes the utility model purpose is: a kind of Stepped Reamers, forms by working portion and shank, the cutting tip of described working portion by more than one, cutter head connection, different-diameter is formed successively.
The cutting tip of described working portion is made up of the cutter head of an above different-diameter, is meant that the diameter of cutting tip changes, and forms stair-stepping cutter head.
Described cutting tip is cylindrical, also can be taper.
The bottom of described cutting tip cutter head bottom is provided with guide cone.
The utility model is combined in the reamer head of various diameters on the reamer, has significantly reduced process time, and machining accuracy also obviously improves, and has reduced processing cost.
Description of drawings
Fig. 1 is the utility model background technology structural representation;
Fig. 2 is the utility model embodiment 1 structural representation.
The specific embodiment
Be described further below in conjunction with drawings and Examples.
