Technical field.
Background technology
In the practical operation of rail vehicle, it is sometimes desirable to according to the design requirement of rail vehicle, to which part portion
Part is transformed, and when being such as transformed to linear motor, wherein the flap seat hole of motor is embedded in alloy steel sleeve at 5, is needed again
φ 39 (+0.016,0) and φ 35 (+0.016,0), and holes concentricity requirement 0.01 are machined to, chipping allowance is about 0.2.When
This size and geometric tolerance be above standard range when, alloy steel sleeve is exited, is embedded in new alloy steel sleeve again, continue plus
Work, until meeting design requirement.
In traditional field of machining, ream finishing generally is carried out using reamer device to hole, part of different shapes exists
Using different reamers during processing.Only there are one guide part and a cutting portions for band for traditional reamer, generally can only be to a hole
It is processed, different holes needs repeatedly processing, for two with concentricity requirement on linear motor of railway vehicle flap seat
A hole, if using traditional reamer, two holes are successively processed, then can not ensure that the concentricity of holes requires, while by
In cutting portion and handle apart from long, when processing, is also easy to produce trembling and causes larger dimensional discrepancy, and not only processing quality is low,
It greatly affected production efficiency.Simultaneously as the position in linear motor flap seat hole is more special, traditional reamer is using extremely
Inconvenience also affects the holes dimensional accuracy after processing to a certain extent.
Invention content
It is of the invention main it is dissatisfied certainly the technical issues of be to provide a kind of simple in structure, easy to operate, and can ensure two after fraising
Pore size and geometric tolerance meet the novel handcraft combination cutter of design requirement.
To achieve the above object, the technical scheme is that：
A kind of novel handcraft combination cutter, including operation handle, handle of a knife and two groups of reamer heads, every group of reamer head is led by one
To portion and a cutting portion composition, the guide part is located at the front end of cutting portion, and two groups of reamer heads are connected by changeover portion.
Further, the distance between two described cutting portion front ends are equal to the pitch-row in two holes.
Further, the cutting portion is equal diameter cylinder.
Further, the guide part at least front end is taper type structure.
Further, the guide part is in integrally taper type structure by top to tail portion.
Further, the taper of the guide part is 85 ° ± 0.05 °.
Further, the diameter deviation of the reamer head at rear portion is smaller 0.005mm than the diameter deviation of forepart reamer head.
Further, the handle of a knife, two groups of reamer heads and changeover portion are structure as a whole.
Further, the handle of a knife is square.
Further, the operation handle is made of the sleeve of front end and the lever of rear end, and the sleeve is sleeved on handle of a knife
On, it is fixedly connected with Top fastening screw.
In conclusion a kind of novel handcraft combination cutter provided by the invention, overall structure is simple, easy to operate, passes through
Two guide parts and two cutting portions are set, while are finished, and do not pacified for two holes on linear motor flap seat
Filling the limitation in space, it is ensured that two pore sizes and geometric tolerance meet design requirement after fraising, solve holes concentricity 0.01,
The processing problem of pore size deviation 0.016.

Fig. 2 is bogie Linear motor mounting structure figure of the present invention；
Fig. 3 is structure chart when reamer of the present invention uses.
As shown in Figure 1 to Figure 3, operation handle 1, sleeve 1a, lever 1b, handle of a knife 2, reamer head 3, guide part 4, cutting portion
5, changeover portion 6, flap seat hole 7, Top fastening screw 8, bushing 9, linear motor 10.
Specific embodiment
The present invention is described in further detail with specific embodiment below in conjunction with the accompanying drawings：
As shown in Figure 1 to Figure 3, a kind of novel handcraft combination cutter provided by the invention, for processing bogie straight-line electric
The inner surface in the flap seat hole 7 on 10 flap seat of machine carries out fine gtinding processing to flap seat hole 7, and flap seat hole 7 is embedded in alloy steel sleeve
9, it needs to re-work to φ 39 (+0.016,0) and φ 35 (+0.016,0), and the concentricity in former and later two flap seat holes 7 exists
In the range of 0.01, chipping allowance is about 0.2mm.
Combination cutter includes operation handle 1, handle of a knife 2 and two groups of reamer heads 3, and every group of reamer head 3 is all by 4 He of guide part
One cutting portion 5 forms, and guide part 4 is respectively positioned on the front end of cutting portion 5, and two groups of reamer heads 3 are connected by changeover portion 6.
In the present embodiment, for ease of assembly and disassembly, preferably handle of a knife 2 using square structure, operation handle 1 by front end set
Cylinder 1a and the cross lever 1b of rear end compositions, sleeve 1a are sleeved on handle of a knife 2, are fixedly connected with Top fastening screw 8, rotation ten
Ream can be realized in the lever 1b of font.In the present embodiment, 2, two groups of reamer heads 3 of handle of a knife and changeover portion 5 are structure as a whole, with
