Further technical scheme of the present utility model is: described sleeve is being provided with bidirectional angular contact thrust ball bearing and Biserial cylindrical roller bearing with supports main shaft one end arranged side by side near thimble one end, and sleeve is at the Biserial cylindrical roller bearing that is provided with away from thimble one end with the supports main shaft other end.
Further technical scheme of the present utility model is: described tailstock main body is externally connected with the travel switch that can control sleeve stroke size.
Because adopt said structure, the numerically controlled lathe hydraulic pressure tailstock structure of the utility model has following beneficial effect:
1, can further improve and improve numerically controlled lathe automaticity, increase work efficiency
Because the numerically controlled lathe hydraulic pressure tailstock structure of the utility model is connected with sleeve in order to the thimble of top tight workpiece, and sleeve moving and moving radially by hydraulic system and control automatically in the horizontal direction, and then thimble in the horizontal direction move and moving radially also controlled automatically by hydraulic system, no longer needing manually to control thimble moves, so the automaticity of numerically controlled lathe can further be improved and improve to given figure car controlling bed hydraulic pressure tailstock structure, reaches the purpose of increasing work efficiency.
2, clamping force size control accurately easily
The numerically controlled lathe hydraulic pressure tailstock structure of the utility model is because the sleeve in the tailstock main body is driven by hydraulic jack, and thimble can have been overcome manual mode clamping force size and be difficult to control shortcoming by regulation of hydraulic system the pressure size and the translational speed of workpiece.
3, accurate positioning and good stability
The numerically controlled lathe hydraulic pressure tailstock structure of the utility model is owing to the cover barrel stroke size in the tailstock main body can be controlled by travel switch, the advance and retreat of sleeve can be controlled by the button on the guidance panel, also can control by floor push, has the automaticity height, workpiece clamps convenient disassembly, accurate positioning and the characteristics that have good stability.
4, long service life
The numerically controlled lathe hydraulic pressure tailstock structure of the utility model has improved main shaft and top rigidity because the spindle support structure in the sleeve adopts front and back end bearing supporting, clamps solid and reliablely, has prolonged service life of tailstock main shaft.
Below in conjunction with drawings and Examples the utility model numerically controlled lathe hydraulic pressure tailstock structure is further described.
