For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of vertical numerical control boring machine, be provided with main motor in the support of boring machine, digital control system is controlled main driven by motor main shaft and is rotated, main shaft drives boring bar, boring machine is provided with Workpiece clamping device, it is characterized in that: described main motor is a frequency conversion master motor, and frequency conversion master motor drives main shaft by belt pulley, and main shaft is direction setting vertically upward; Workbench is located at the boring bar top, and workbench is provided with Workpiece clamping device, and workbench is connected with slide unit; The column case is equipped with in the support top, feeding driven by motor screw mandrel, and screw mandrel drives slide unit and moves up and down on column; Digital control system control main axis rotation and working table movement, porose in the middle of the workbench, boring bar passes this hole processing work.
Advantage of the present utility model is: because main shaft is direction setting vertically upward, workbench is located at the boring bar top, and workbench is driven by slide unit and moves up and down on column, and is porose in the middle of the workbench; Make workpiece in process, smear metal falls by the workbench interstitial hole, and chip removal is smooth and easy.Particularly when processing blind hole, the smear metal that falls can not be deposited in the hole vertical numerical control boring machine of the present utility model, thereby has improved the precision of bore hole.Because frequency conversion master motor drives main shaft by belt pulley, the feeding motor drives workbench by screw mandrel, and it can make simple in structure, the motion stabilization of the utility model, low cost of manufacture.
In the utility model, be provided with channel of chip removal around the described main shaft, there is chip removal mouth the support side, and smear metal and cutting fluid are discharged to the side along stand bevel, and said structure can make chip removal smooth and easy.
In the utility model, described column case connects two columns, four guide pin bushings is installed up and down, and is provided with dust ring.Said structure can make movable workbench steady.
In the utility model, described Workpiece clamping device comprises: two cylinders and depression bar, two cylinder left-right symmetry are distributed in the workbench both sides.It can make the Workpiece clamping device reliable operation.
In the utility model, described main shaft is provided with the main shaft orienting device, the main shaft orienting device comprises: the main shaft lower end is equipped with adjusting ring, adjusting ring is being fixed sense contact, be fixed with inductive switch on the support, the rotation adjusting ring is adjusted the mutual alignment of sense contact and boring cutter and is adjusted the directed withdrawing of boring bar on the main shaft.
Description of drawings
Fig. 1 cuts open structural representation for before of the invention process.
Fig. 2 cuts open structural representation for side of the invention process.
The specific embodiment
In conjunction with Fig. 1, shown in Figure 2: the vertical numerical control boring machine of present embodiment comprises: be provided with main motor 2 in the support 1 of boring machine, main motor is a frequency conversion master motor, and frequency conversion master motor drives main shafts 17 by belt 3, the main shaft 17 outer sleeves 16 that are provided with.Digital control system is controlled main driven by motor main shaft and is rotated, and main shaft drives boring bar 7.
Described main shaft 17 is direction setting vertically upward, and the main shaft orienting device is located at the main shaft bottom; Workbench 8 is located at boring bar 7 tops, and workbench is provided with Workpiece clamping device, and workbench 8 is connected with slide unit 11; Column case 6 is equipped with in the support top, and screw mandrel 23 links to each other with feeding motor 19 by shaft coupling 18, and feeding motor 19 drives screw mandrel 23, and screw mandrel drives slide unit 11 and moves up and down on column 14; Digital control system 12 control main axis rotation and working table movement, porose in the middle of the workbench 8, boring bar 7 passes this hole processing work 9.
The main shaft orienting device comprises: the main shaft lower end is equipped with adjusting ring 15, and adjusting ring is being fixed sense contact 5, is fixed with inductive switch 4 on the support, and the rotation adjusting ring is adjusted sense contact 4 and adjusted the directed withdrawing of boring bar on the main shaft with the mutual alignment of boring cutter 20.
Boring machine is provided with Workpiece clamping device, and Workpiece clamping device comprises: two cylinders 13 and depression bar 10, two cylinder left-right symmetry are distributed in the workbench both sides.It can make the Workpiece clamping device reliable operation.
