Technical field
The present invention relates to the compression impellor manufacture field of turbocharger, particularly a kind of manufacture method of blind hole compression impellor.
Background technology
In recent years, because diesel engine is to high-performance, high efficiency, energy-saving future development, higher requirement is proposed to the structural compactness of turbocharger, aesthetic appearance, security reliability.Compression impellor is the core part that turbocharger high speed is rotated, and for diesel engine provides the compressed air of certain pressure ratio, improves the efficiency of diesel engine.
Along with improving constantly of technology for Turbocharger Manufacturing, updating of compression impellor structure, up to the present, compression impellor has developed into the form of blind hole unitary tape deviated splitter vane, the dimensional accuracy of itself and form and position tolerance required precision all improve, and traditional compression impellor manufacture method has been difficult to ensure its required precision, because traditional handicraft operation is various, ageing equipment precision is not high, causes production efficiency very low.
Summary of the invention
For solving the problem, the object of the present invention is to provide a kind of manufacture method of blind hole compression impellor, ensureing machining accuracy, improve working (machining) efficiency.
For achieving the above object, technical scheme of the present invention is as follows: the manufacture method of blind hole compression impellor, comprises the following steps: step one, clamping impeller blank on numerical control vertical lathe, turnery processing bottom end face, bottom cylindrical, back of the body arc and large cylindrical, use reamer processing blind hole; Step 2, presss from both sides large cylindrical with three-jaw, by flat bottoms end face, and turnery processing meridian plane and top end face; Step 3, utilizes bottom end face to locate, and is connected, turnbuckle with bolt with blind threaded, and carries on the back arc and bottom cylindrical by clamp, thread mill drilling, Milling Process inner hexagonal hole, blade and runner.
Preferably, turnery processing bottom end face in step one, bottom cylindrical, back of the body arc and large cylindrical adopt and same lathe tool to be completed.
Preferably, described impeller blank through step one operation processing after, with three-dimensional detector detect, detect qualified after enter step 2.
Preferably, the turnery processing of step 2 carries out on numerical control vertical lathe.
Preferably, step 3 is carried out on five-shaft linkage numerically controlled machine.
Preferably, in step 3 Milling Process divide rough mill, half finish-milling, finish-milling to complete processing, wherein rough milling maximum speed is 12000 revs/min, and the amount of feeding is up to 5000 mm/min.
Adopt the manufacture method of blind hole compression impellor of the present invention, ensure that machining accuracy, decrease process equipment, shorten manufacturing procedure, decrease the process time of workpiece, improve production efficiency, thus reduce manufacturing cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of the blind hole compression impellor adopting the manufacture method of blind hole compression impellor of the present invention to process.
Detailed description of the invention
Be described in further details below in conjunction with the manufacture method of accompanying drawing to blind hole compression impellor of the present invention.
See Fig. 1, the manufacture method of blind hole compression impellor of the present invention, comprises the following steps:
Step one, clamping impeller blank on numerical control vertical lathe, turnery processing bottom end face 5, bottom cylindrical 7, back of the body arc 6 and large cylindrical 1, with reamer processing blind hole 8, described impeller blank is solid forging die part, and turnery processing is fine finishining, reamer can adopt high precision reamer, guarantees machining accuracy.Turnery processing bottom end face 5, bottom cylindrical 7, back of the body arc 6 and large cylindrical 1 adopt and same lathe tool to be completed, and guarantee machining accuracy.Described impeller blank through step one operation processing after, can with three-dimensional detector detect, detect qualified after enter next step operation.
Step 2, presss from both sides large cylindrical 1 with three-jaw, by flat bottoms end face 5, guarantees that bottom end face 5 contacts gapless, turnery processing meridian plane 2 and top end face 4.The turnery processing of step 2 also carries out on numerical control vertical lathe.
Step 3, utilizes bottom end face 5 to locate, is threaded with bolt with blind hole 8, turnbuckle, and carries on the back arc 6 and bottom cylindrical 7 by clamp, thread mill drilling 10, Milling Process inner hexagonal hole 9, blade 11 and runner 3.The operation of step 3 is carried out on five-shaft linkage numerically controlled machine.First hole during thread mill drilling 10, then tapping.Cam milling tool can be adopted during Milling Process inner hexagonal hole 9 to carry out.
Through above-mentioned last step, namely whole operation has accused.The step one of this manufacture method and the operation of step 2 change numerical control vertical lathe into by traditional numerical control sleeping carriage, same as lathe tool finish turning bottom end face 5, bottom cylindrical 7, back of the body arc 6 and large cylindrical 1 in the operation of step one, positioning datum and step one operation of its step 2 operation of effective guarantee overlap completely, cut with scissors three grades of holes in blind hole 8 with high precision reamer simultaneously.
Step 3 utilizes bottom end face 5 to locate, and is threaded with blind hole 8 with bolt, turnbuckle, and with clamp back of the body arc 6 and bottom cylindrical 7, ensure that the stability of positioning precision and high-speed milling fully.Step 3 can utilize five kinds of different tapering milling cutters to divide which floor milling, and point to rough mill, half finish-milling, finish-milling to complete processing, wherein rough milling maximum speed can reach 12000r/min, and the amount of feeding reaches as high as 5000mm/min.
Adopt manufacture method of the present invention, decrease process equipment, shorten manufacturing procedure, decrease the process time of workpiece, improve production efficiency, thus reduce manufacturing cost.
