Abstract
The utility model relates to a boring lathe of a large hole and a through hole on a boring processing component. The boring lathe comprises a lathe bed, wherein, a wheel box and a supporting seat are respectively mounted at both ends of the lathe bed. The boring lathe of a large hole and a through hole on a boring processing component is characterized in that one end of a boring mechanism is connected with the wheel box, and the other end can be rotationally connected with the supporting seat. Because a radial rotary boring mechanism and an axial feed mechanism are finished on the same axes of the same mechanism, the processing precision is greatly increased; the length of a work piece processed and the axial feed length are overlapped in boring, the total length of the lathe bed is shortened; a sliding seat replaces the components of a traditional machine tool such as a slide way, a sliding plate, and the like, thereby the manufacturing cost is reduced.

Above-mentioned supporting base comprises base, and on base, bearing holder device is on sliding seat by pin shaft device for sliding seat.
Device has the toolsetting nut between above-mentioned borer and the tool rest.
One side of above-mentioned slide is provided with notch, and device has the accent feeler in the notch.
Technique effect of the present utility model is:
1. radially rotate boring mechanism and axial feed mechanism and on the same axis of same mechanism, finish, improved machining accuracy.
2. the axial feed length when work piece length and boring is overlapping, has shortened the total length of lathe.
3. slide has substituted the parts such as guide rail slide plate of traditional machine tool, has reduced manufacturing cost.

Fig. 1 is the utility model structural representation.
Fig. 2 is the A portion enlarged drawing of Fig. 1.
Fig. 3 is that the B-B of Fig. 2 is to view.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
As shown in Figure 1, the utility model comprises lathe bed 4, and transmission case 1 and supporting base 3 are installed on the two ends of lathe bed 4 respectively, and an end of boring mechanism 2 is connected with transmission case 1, and the other end is connected with supporting base 3 rotationally.Add man-hour in boring, boring mechanism 2 is passed needs the hole that processes on the workpiece 5, and workpiece 5 is fixed on the workbench 401 of lathe bed 4.As shown in Figure 1, 2, 3, boring mechanism 2 comprises hollow shaft 207, and the one end connects transmission case 1, and the other end is installed to by bearing on the bearing block 304 of supporting base 3, and transmission case 1 drives hollow shaft 207 rotations.Slide 206 passes through dive key 208 carriages on hollow shaft 207, slide 206 can horizontally slip along dive key 208 and hollow shaft 207, and bear the radially moment that boring adds man-hour by dive key 208, in the present embodiment, one side of slide 206 is provided with notch, device has the feeler 213 of accent in the notch, and by transferring crack fastening bolt 212 fastening, adjust to transfer the thickness of feeler 213 can adjust fit clearance between slide 206 and the hollow shaft 207, thereby guarantee slide 206 steadily slippage and guarantee the precision that boring is processed on hollow shaft 207.The shank of borer 201 is square, cooperate with the square hole on the tool rest 204, device has toolsetting nut 202 between borer 201 and the tool rest 204, adjust the radial position of borer 201 with toolsetting nut 202, be carved with the scale (not shown) respectively on toolsetting nut 202 and the tool rest 204, when adjusting the radial position of borer 201, can control adjustment amount.Tight cutter nut 211 fastens the shank of borer 201, and tool rest 204 usefulness screws 205 fixtures are on slide 206.Feed screw 210 is installed in the hollow shaft 207, the one end connects transmission case 1, the other end is by the axle head of bearing arrangement in hollow shaft 207, transmission case 1 drives feed screw 210 and rotates, the feed nut 209 that is installed on the feed screw 210 connects slide 206 by tight cover 203, in the present embodiment, the connecting rod of feed nut 209 1 sides inserts tight cover 203, and be matched in clearance between the tight cover 203, tight cover 203 connects slide 206 and tool rest 204, tight cover 203 and tool rest 204 interference fit drive tool rest 204 better and borer 201 is made axial feed motion.
