Abstract

The utility model provides a combined rimer which comprises a rimer head and a handle. The rimer head comprises more than two groups of blades extending from the end of the rimer head to the rear portion, and machining diameters of the blades are increased to form a step shape. Each group of blades comprises two pairs of symmetrical blades. A plurality of layers of blade portions with different diameters are arranged on a rimer body of the rimer, machining of step holes can be finished through one step, coaxiality of holes is well guaranteed, and the depth of the holes can be guaranteed.

Description

Compound reamer
Technical field
The utility model relates to a kind of compound reamer.
Background technology
Reamer, for drilling (or reaming) processing Hou hole on ream workpiece, is mainly in order to improve the machining accuracy in hole, reduces its surperficial roughness, is fine finishining and semi-finished cutter for hole, and its allowance is generally very little.Along with the development of machinery industry, user is to having proposed requirements at the higher level delivery date of the crudy of product, process reliability, cutter etc.General reamer once can only complete a kind of processing of hole of diameter, causes the precision in working (machining) efficiency Di, hole not high.
Utility model content
For the defect existing in prior art and deficiency, the utility model proposes a kind of compound reamer that can once complete shoulder hole.Described technical scheme is as follows:
The utility model proposes a kind of compound reamer, comprise cutter head and handle of a knife, described cutter head comprises the blade of two groups of above stepped increases of processing diameter of being extended to rear portion by cutter head end, and described every group of blade comprises two pairs of symmetrically arranged blades.
Preferential as technique scheme, the coupling part of described two groups of adjacent blades is provided with transition blade.
Preferential as technique scheme, described handle of a knife is taper shank.
Preferential as technique scheme, described two pairs of symmetrically arranged blades are radially vertical.
Preferential as technique scheme, the stepped setting of described transition blade or be obliquely installed.
The beneficial effect that the technical scheme that the utility model embodiment provides is brought is: the utility model proposes a kind of compound reamer, the cutter hub of this cutter is provided with the blade of some layers of different processing diameter, can once complete the processing of shoulder hole, well guarantee the axiality of Kong Yukong, and can guarantee the degree of depth in hole.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 provides carpenter to use high speed planning tool structure schematic diagram in the present embodiment 1.
The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the utility model embodiment is described in further detail.
Embodiment 1
The utility model proposes a kind of compound reamer, as shown in Figure 1, comprise cutter head 2 and handle of a knife 1, described cutter head 2 comprises the blade of two groups of above stepped increases of processing diameter of being extended to rear portion by cutter head end, and described every group of blade comprises two pairs of symmetrically arranged blades.
The coupling part of described two groups of adjacent blades is provided with transition blade.
Described handle of a knife is taper shank.
Described two pairs of symmetrically arranged blades are radially vertical.
The stepped setting of described transition blade or be obliquely installed.
The utility model proposes a kind of compound reamer, the cutter hub of this cutter is provided with the blade of some layers of different processing diameter, can once complete the processing of shoulder hole, has well guaranteed the axiality of Kong Yukong, and can guarantee the degree of depth in hole.
Embodiment, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
