Description
Technical field
The present invention relates to a kind of thin-walled ring axial step deep hole system processing method, belong to thin-walled annulate shaft to stepped hole processing technique field.
Background technology
Thin ring wall axial step deep hole system is processed as universal machine process technology.Current existing thin ring wall axial step deep hole system tooling step is tediously long, and the processing difficulties of the thinnest ring wall axial step deep hole architecture mainly has everywhere: 1) radial direction (diametric(al)) Static stiffness of thin-walled ring body is not enough, it is easy to clamping unstability occurs；2) axis of step deep hole be easy to deviation, depth of parallelism 0.06mm it is difficult to ensure that；3) tooling step of step deep hole system is numerous and diverse, working (machining) efficiency the lowest (about 6h)；4) φ 7.5H8(in step deep hole) mm hole and φ 6H8() mm hole axiality φ 0.015mm it is difficult to ensure that.
Summary of the invention
For solving what prior art existed technical problem, the invention provides a kind of simple to operate, machining accuracy is high, work efficiency significantly improves thin-walled ring axial step deep hole system processing method.
For achieving the above object, the technical solution adopted in the present invention is a kind of thin-walled ring axial step deep hole system processing method, follows the steps below,
A, thin-walled ring body is horizontally fixed on operating board, by the clamp pressing on operating board；
B, centre drill is used to get out the positioning center hole of step deep hole at the end face of thin-walled ring；
In c, employing hard alloy, cold drill bit gets out the prebored hole of macropore in step deep hole on positioning center hole；
D, employing guide to be drilled on positioning center hole and get out the bullport of aperture in step deep hole；
E, use hard alloy again in cold drill bit in bullport, get out the prebored hole of aperture in step deep hole；
Cold spiral cutting sword step combined shaping reamer in f, finally employing hard alloy, one-time positioning has been cut hole wall and the step of step deep hole, has been machined.
Preferably, when boring, the circular runout of drill bit is not more than 0.003mm.
Preferably, in described step e, drill bit answers the slow-speed of revolution, the little amount of feeding to enter, and after suspending several seconds, then is processed with normal rotating speed and the amount of feeding.
Preferably, in described step a, the screw-down torque scope of fixture is 9N m～10N m.
Preferably, in described step f, reamer geometry agrees with the shape of step deep hole, and the axiality of step two cylindrical is not more than 0.002mm.
Compared with prior art, the present invention has following technical effect that the present invention uses decreasing pore size substep semifinishing step deep hole, the principle of deviation more it is difficult to based on drilling more shallow bore hole axis, first process large diameter hole, reprocessing small diameter bore, by hole depth being shared to shorten the degree of depth of single drilling in each drilling work step, thus ensure the positioning precision of step deep hole entirety axis, the depth of parallelism；The shortest based on processing chain, that working (machining) efficiency is the highest principle, by above processing method, reduces tooling step, thus improves working (machining) efficiency；Using cold spiral cutting sword step combined shaping reamer in hard alloy, one-time positioning has cut step deep hole hole wall, the overall ream of step shapes, thus ensures the axiality of step deep hole, surface roughness requirements simultaneously.
Detailed description of the invention
In order to make the technical problem to be solved, technical scheme and beneficial effect clearer, below in conjunction with embodiment, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
A kind of thin-walled ring axial step deep hole system processing method, it is characterised in that: follow the steps below,
A, thin-walled ring body is horizontally fixed on operating board, by the clamp pressing on operating board；Using pressing plate along the axial compression thin-walled ring body end face of thin-walled ring body, pressure point is uniform along thin-walled ring body circumferential end surfaces, and the screw-down torque scope of fixture is 9N m～10N m.Owing to the radial direction Static stiffness of thin-walled ring body is not enough, relative to using the process unit clampings such as scroll chuck, chuck, pressing plate, more difficult generation clamping deformation and clamping unstability；
B, centre drill is used to get out the positioning center hole of step deep hole at the end face of thin-walled ring；
In c, employing hard alloy, cold drill bit gets out the prebored hole of macropore in step deep hole on positioning center hole；
D, employing guide to be drilled on positioning center hole and get out the bullport of aperture in step deep hole；
E, use hard alloy again in cold drill bit in bullport, get out the prebored hole of aperture in step deep hole；Drill bit answers the slow-speed of revolution, the little amount of feeding to enter, and after suspending several seconds, then is processed with normal rotating speed and the amount of feeding.
F, finally using cold spiral cutting sword step combined shaping reamer in hard alloy, one-time positioning to cut hole wall and the step of step deep hole, machined, reamer geometry agrees with the shape of step deep hole, and the axiality of step two cylindrical is not more than 0.002mm.
When boring, the circular runout of drill bit is not more than 0.003mm, ensures that cutter is sufficiently cool simultaneously.
The present invention use quantization moment axial clamping thin sheet ring wall end face technique can realize the stable state of thin-walled ring body, without deformation clamping；Use decreasing pore size substep semifinishing step deep hole simultaneously, the principle of deviation more it is difficult to based on drilling more shallow bore hole axis, first process large diameter hole, reprocessing small diameter bore, by hole depth being shared to shorten the degree of depth of single drilling in each drilling work step, thus ensure the positioning precision of step deep hole entirety axis, the depth of parallelism；The shortest based on processing chain, that working (machining) efficiency is the highest principle, by above processing method, reduces tooling step, thus improves working (machining) efficiency；Using cold spiral cutting sword step combined shaping reamer in hard alloy, one-time positioning has cut step deep hole hole wall, the overall ream of step shapes, thus ensures the axiality of step deep hole, surface roughness requirements simultaneously.
