Abstract
The utility model relates to a boring device for a sliding pillow, which belongs to the field of machine tools. The boring device is provided with a lathe bed and is characterized in that a power head is mounted on the lathe bed via a ball screw, a workbench is positioned at one end of the lathe bed, a boring cutter bar is mounted on the workbench via a front support and a rear support, a reference pad is mounted on the workbench at the rear part of the rear support, and the power head is linked with the boring cutter bar through a universal joint. A workpiece is placed on the machine tool and does not need to be adjusted during usage; the mounting is convenient, direct boring can be performed after clamping the workpiece, the precision is high, multiple rows of holes can be machined together, and the efficiency is high.
Description
Technical field
The utility model relates to machine tool field, especially a kind of ram boring device.
Background technology
As everyone knows, at present, in disposing the boring machine product of ram, ram is extremely important parts, the effect of starting executing agency in lathe.The processing of ram and assembly precision directly have influence on the complete machine performance, special its machining accuracy directly has influence on assembly precision again, but because ram length is all about 3 meters, middle two row's dead eye diameters are all greater than 0.38 meter, span is difficult to guarantee the size and the Geometrical Tolerance Principle of dead eye greater than 0.5 meter for machine tool; And the center line and the ram of two row's dead eyes have high depth of parallelism requirement on four sides, and this requirement has increased the manufacturing difficulty of processing again greatly.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of ram boring device, and workpiece is placed on and need not on the lathe to adjust, and is easy for installation, direct bore hole behind the clamping work pieces, precision height; Many rounds can be processed together, the efficient height.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of ram boring device, be provided with lathe bed, it is characterized in that through ball-screw unit head being installed on the lathe bed, workbench is positioned at lathe bed one end, on the workbench through preceding support and after support boring cutter bar be installed, the back is supported on the workbench at rear portion reference pads is installed, and connects by universal joint between unit head and the boring cutter bar.
The beneficial effects of the utility model are that workpiece is placed on and need not on the lathe to adjust; Easy for installation, direct bore hole behind the clamping work pieces, the precision height, many rounds can be processed together, the efficient height.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model
1. lathe beds among the figure, 2. unit head, 3. universal joint supports before 4., 5. boring cutter bar, 6. the back is supported, 7. reference pads, 8. workbench.
The specific embodiment
In Fig. 1, the utility model is provided with lathe bed 1, through ball-screw unit head 2 is installed on the lathe bed 1, workbench 8 is positioned at lathe bed 1 one ends, on the workbench 8 through preceding support 4 and after support 6 boring cutter bar 5 be installed, the back is supported on the workbench 8 at 6 rear portions reference pads 7 is installed, and connects by universal joint 3 between unit head 2 and the boring cutter bar 5.
First half of the present utility model is made up of lathe bed 1, unit head 2 and universal joint 3, belongs to the power source part.Latter half is made up of preceding support 4, boring cutter bar 5, back support 6, reference pads 7 and workbench 8, and part is installed on the reference pads 7 of workbench 8, varies in size according to ram, disposes different reference pads.Because reference pads 7 and preceding support 4, back support 6 strict position accuracy demand is arranged directly,, do not need independent centering, save time so part only need be adjacent to clamping.
Unit head 2 moves by before and after ball-screw is on lathe bed, finishes boring cutter bar 5 feed motions.Connect by universal joint 3 between unit head 2 and the boring cutter bar 5, universal joint 3 can effectively reduce the error of the first half generation of ram boring device, and support 4 and back support 6 are finished before the assurance of bore hole precision then.The ram boring device is divided into the front and rear part can effectively isolate vibration source, guarantees machining accuracy.
According to the position dimension in ram inner bearing hole, rationally on boring cutter bar 5, arrange different boring cutter piece installing holes, thereby can realize that a plurality of holes process simultaneously, increase work efficiency.
