The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Shown in accompanying drawing, the said boring device of the utility model comprises boring bar 9, boring bar Support bracket 2, boring bar holder 3 and lubricating and cooling 4.Wherein, an end of boring bar 9 is clipped on the boring bar holder 3, and after boring bar 9 was put into the hole of rotating shaft 2, boring bar 9 was placed on the boring bar Support bracket 2, and boring bar 9 links to each other with cooling and lubricating device 4.
The surface of boring bar 9 is provided with brace rod 10, and sliver 11 is embedded in the brace rod 10, and fixing with bolt 12.Cutter box 14 usefulness straight pin I 18 are fixedly connected on the boring bar 9, and pull bar 15 usefulness straight pin II 19 are connected with cutter box 14, and can drive cutter box 14 and rotate around straight pin I 18.Cutting tool 31 usefulness screws 16 are fixed on the cutter box 14.The end plate 20 of the operating side of pull bar 15 is provided with the hole, can pull bar 15 is fixing through being screwed into nut 17 in the hole on end plate 20.Have the road groove 30 of a sealing in brace rod 10 sides of boring bar 9, this sealing road groove 30 leads to cutting tool 31 edges of a knife of cutter along brace rod 10.
Boring bar Support bracket 2 comprises base plate 21, crossbeam 22, ram 23, support bar 24, screw rod 25.Wherein, base plate 21 is fixed by bolts on the lathe, and ram 23 is sleeved on the crossbeam 22.Ram 23 can laterally move on crossbeam 22.The stayed surface that ram 23 contacts with boring bar 9 is provided with roller 26, and boring bar 9 can easily move when the centre bore of turnover rotating shaft 2 in the vertical like this.Support bar 24 and screw rod 25 are connected through screw with crossbeam 22 respectively.Screw rod 25 can turn up and down, and so that the whole height of boring bar bracing frame 2 is finely tuned, 24 of support bars can highly be regulated with the fine setting of screw rod 25.After highly regulating completion, support bar 25 is fixing through the clamp nut 32 of bottom, thereby the height of realizing whole boring bar Support bracket 2 is regulated.
