The manufacturing procedure and clamping times of workpiece, and each processing end face is required at anchor point to reference zero in process
Point confirmation position, complex for operation step repeatedly to knife, caller, processing efficiency is low, and processing quality not can guarantee.
Summary of the invention
The present invention overcomes clamping times when cylinder list partly processes multiple positions in the prior art, repeatedly walk to knife, operation
Rapid cumbersome, processing efficiency is low, the deficiency that processing quality not can guarantee, and a kind of conjunction cylinder processing method of cylinder is provided, only with one
It is secondary to knife, workpiece centre caused by calculating because of faying face allowance and processing the centre of gyration it is inconsistent caused by position deviation value,
And compensated in numerical control program, it realizes that cylinder closes cylinder processing on digital-control boring-milling machine, completes all boring and millings under clamped one time
The processing of bed sequence, improves processing efficiency and processing quality.
A kind of conjunction cylinder processing method of cylinder, includes the following steps:
Work centre and centre of gyration difference confirm: the workpiece for closing cylinder be placed on digital-control boring-milling machine rotary table,
The machine direction of boring and milling machine is+Y-axis, so that in the revolution of the centre of gyration of workpiece and digital-control boring-milling machine revolution work centre platform
Projection of the heart in the face XOZ is overlapped and the faying face of conjunction cylinder is parallel to XOY datum level, determines that workpiece centre and the workpiece centre of gyration exist
Projector distance, that is, the work centre and centre of gyration difference D in the face XOZ；
Calculate each machine direction difference after workpiece rotates: the plane and XOY base that rotation rotary table α degree is processed needed for making
Quasi- face is parallel, calculates separately the difference DELTA X of X-direction and the difference DELTA Z of Z-direction；
Numerical control program numerical compensation calculates: all directions difference is fitted to processing program code respectively after calculating workpiece rotation
All directions numerically, form final machining code.
Further, the workpiece centre is the workpiece centre of gyration defined in workpiece drawing.
Further, the processing program code is based on the processing program worked out on the basis of workpiece centre.
Further, the difference DELTA X=DSin α of the X-direction, the difference DELTA Z=DCos α of the Z-direction.
Further, the processing numerical value of the processing program code X-direction is X1, the processing program code Z-direction
Processing numerical value is Z1.
Further, the processing numerical value X=X1+ Δ X of the final machining code X-direction, it is described final plus
The processing numerical value Z=Z1+ Δ Z of work code Z-direction.
A kind of conjunction cylinder processing method of cylinder, realizing cylinder can be in numerical control floor type boring and milling machine when faying face has allowance
It carries out conjunction cylinder to process, a whole set of cylinder clamped one time once completes knife the processing of periphery, reduces the clamping workpiece time, and raising adds
Work efficiency rate, and only need once when processing to knife, processing problems caused by avoiding because of tool-setting error improve workpiece processing quality.
