Description
Technical field
The present invention relates to a kind of control method of lathe, especially relate to the safety zone control method of boring cutter on a kind of lathe.
Background technology
Along with development and the improvement of processing technology, turning center is for boring cutter, and especially the process requirements of extended type boring cutter constantly increases.But the length of boring cutter is generally all more than 500mm, this type of cutter is used to carry out adding and there will be a lot of safety problems man-hour.Due to this type cutter customization expensive, customization the cycle long, so how to guarantee this kind of cutter can safety for process just seem extremely important.In addition, the cutterhead of lathe has been installed long boring cutter bar, if will carry out follow-up tool changing processing, existing way is generally first dismantled by boring cutter, then on cutterhead, again installs new cutter process, and wastes time and energy.
Summary of the invention
Technical problem to be solved by this invention is: for the deficiencies in the prior art, the safety zone control method of boring cutter on a kind of lathe is provided, lathe tool changing can be realized by the method and add the control of safety zone of boring cutter in man-hour, such boring cutter need not be dismantled after installing, and the tool changing of lathe and processing can be carried out under safe and reliable condition.
The present invention solves the problems of the technologies described above adopted technical scheme: the safety zone control method of boring cutter on a kind of lathe, comprises the following steps:
1) at the top of cutterhead, some boring cutters are installed, in the bottom of cutterhead, some lathe tools are installed; An opening offered by the panel beating protective cover relative with described cutterhead of lathe, and described opening is relative with the position of described some boring cutters, and the periphery along described opening on described panel beating protective cover is provided with the extension stretching to lathe Z axis negative direction;
2) in the cutter number installing boring cutter and lathe tool, select a cutter number as target cutter number, after determining target cutter number, first whether X-axis is judged at co-ordinate zero point, if through judging that X-axis is not at co-ordinate zero point, should first make X-axis be back to co-ordinate zero point, more whether Z axis is judged in safety zone; If through judging whether X-axis is at co-ordinate zero point, directly judge in safety zone Z axis;
If through judging that Z axis is not in safety zone, should first make Z axis be back to safety zone, then carry out next-step operation; If through judging that Z axis is in safety zone, directly carries out next-step operation;
3) judge that target cutter number is boring cutter place cutter number or lathe tool place cutter number, if through judging that boring cutter place cutter number is target cutter number, first rotary head, make boring cutter turn to the current cutter spacing of lathe, tool changing completes, because now Z axis is limited, Z axis stroke reduces, X-axis is total travel, and X-axis is not limited, therefore should carry out boring processing according to the Z axis stroke after reduction and normal X-axis total travel;
If through judging that lathe tool place cutter number is target cutter number, first rotary head, target cutter spacing is made to turn to current cutter spacing, tool changing completes, now Z axis is total travel, can carry out turnery processing, before carrying out turnery processing, first judge that whether Z axis is in safety zone, more whether in safety zone, the stroke of X-axis is adjusted according to Z axis; If through judging that Z axis is not in safety zone, then X-axis is limited, and X-axis stroke reduces, and therefore should carry out turnery processing according to the X-axis stroke after reduction; If through judging that Z axis is in safety zone, then X-axis is not limited, and X-axis is total travel, therefore can carry out normal X-axis total travel machining.
Compared with prior art, the invention has the advantages that: boring cutter and lathe tool have been installed on lathe, the inventive method can realize the tool changing of lathe in safety zone and normal process, and the conversion realized between the boring processing of lathe and turnery processing, be equivalent to for lathe is provided with the crashproof district of shielding, after making installation boring cutter carry out boring processing, follow-up carry out turnery processing before need not dismantle boring cutter, the turnery processing of lathe is not affected yet, the collision decreasing boring cutter and lathe may, guarantee safety, reduce processing cost simultaneously; And after using the inventive method, the time of dismounting boring cutter significantly reduces, thus shortens processing beat, improves working (machining) efficiency.
Accompanying drawing explanation
Fig. 1 is the scheme of installation of lathe and boring cutter in embodiment, lathe tool.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the present invention is described in further detail.
The safety zone control method of boring cutter on the lathe of embodiment, comprises the following steps:
1) as shown in Figure 1, adopt and there is the cutterhead 2 of 12 cutter spacing, install three at the top of cutterhead 2 and namely boring cutter 6(be installed on 9,10 and No. 11 cutter spacing in Fig. 1), install three in the bottom of cutterhead 2 and namely lathe tool 7(be installed on 3,4 and No. 5 cutter spacing in Fig. 1); An opening 4 offered by the panel beating protective cover 3 relative with cutterhead 2 of lathe 1, opening 4 with three relative for the position of boring cutter 6, panel beating protective cover 3 is provided with along the periphery of opening 4 extension 5 of the Z axis negative direction of stretching to lathe 1, when Z axis moves left and right, three can to stretch into boring cutter 6 in opening 4 and move left and right;
2) determine that the target cutter number of tool changing is No. 9 cuttves, due to X-axis not at co-ordinate zero point, Z axis not in safety zone, therefore first X-axis is moved to the forward zero point of lathe 1, and Z axis is moved to safety zone, then carry out next-step operation;
3) because No. 9, boring cutter 6 place cutter number is target cutter number, first rotary head 2, make No. 9 boring cutters 6 turn to the current cutter spacing of lathe 1, tool changing completes, because now Z axis is limited, Z axis stroke reduces, X-axis is total travel, and X-axis is not limited, therefore should carry out boring processing according to the Z axis stroke after reduction and normal X-axis total travel, avoid the interference of chuck 9, sheet metal component and the workpiece 8 on the left of boring cutter 6 pairs of lathes 1, the Z axis stroke size being specifically limited to reduce is relevant with the length of boring cutter 6.
In above-described embodiment method, if determine that No. 5 lathe tools are the target cutter number of tool changing, X-axis is moved to the forward zero point of lathe 1, after again Z axis being moved to safety zone, first rotary head 2, No. 5 lathe tools are made to turn to current cutter spacing, tool changing completes, due to the existence of the opening 4 on panel beating protective cover 3 and extension 5, boring cutter 6 can not cause interference in Z-direction, thus now Z axis is total travel, turnery processing can be carried out, and in X-direction, due to the impact by the sheet metal component beyond chuck 9 and extension 5, Z axis is not in safety zone, X-axis stroke will reduce, therefore turnery processing should be carried out according to the X-axis stroke after reduction.
