Description
Technical field
The present invention relates to field of machining, and in particular to deep hole thin-walled cylinder barrel processing method.
Background technology
K25 rigs are Safety of Coal Mine Production necessary equipments, are mainly used in the probing of underground water.Cylinder barrel is the master on the rig
Part is wanted, the inner hole of cylinder required precision is high, and especially surface roughness requirements are high, is not allow for the tool marks of transverse direction and longitudinal direction；From
Cylinder structure can be seen that the part and belong to long sleeve structure, belong to thin wall and deep hole processing, and endoporus difficulty of processing is big.
The content of the invention
In order to solve the above problems, the present invention, which provides one kind, can improve production efficiency, ensure workpiece processing quality, reduce life
Cost is produced, reduces the deep hole thin-walled cylinder barrel processing method of labor strength.
Deep hole thin-walled cylinder barrel processing method of the present invention, comprises the following steps,
The first step, seamless steel pipe is selected in blanking, and leaves certain allowance；
Second step, rough turn, the clamping workpiece on lathe, the endoporus and excircle of workpiece of rough turned piece；
3rd step, half smart car, half smart car inner hole of workpiece, and car falls the redundance on Workpiece length direction；
4th step, finishing, positioning and guiding set is installed in the inner hole of spindle of lathe, by external cooling and lubricating liquid pipe from main shaft
Hole rear end penetrates to be coupled with the oilhole on finishing of internal diameter knife, and the guide sleeve part of finishing of internal diameter knife is loaded in advance
In the endoporus of positioning and guiding set, the cutter hub length of finishing of internal diameter knife should determine according to Workpiece length, it is ensured that the connection of knife tail
Part can expose from the endoporus of workpiece to be machined；
5th step, knife bar is installed on the knife rest of lathe, and adjusts knife bar centre-height；
6th step, opening cutting ferrule is first blocked on the claw of lathe, in the built-in workpiece of opening cutting ferrule, is gently clamped, with centre frame frame
The workpiece other end, finishing of internal diameter knife is coupled with knife bar, start lathe, feed reversing finishing endoporus；
7th step, rolling, during rolling and processing, workpiece is loaded identical with finishing endoporus, and finishing of internal diameter knife is changed into stitching
Couple with knife bar, stitching is to headstock direction through-feed rolling endoporus.
Preferably, finishing of internal diameter knife blade hook angle is 10 °, and relief angle is 5 °, and tool cutting edge angle is 86 ° -106 °, and two blades are radially
Distance is adjusted to diameter 9.95mm, and symmetry is less than 0.01mm.
Preferably, 0.04mm~0.06mm allowance is stayed when finishing endoporus.
Preferably, cylinder barrel rolling feed speed is 50 mm/min.
The present invention can improve production efficiency, ensure workpiece processing quality, reduce production cost, reduce labor strength.
