Description
Technical field
The utility model relates to the revolution hydraulic pressure tail roof construction on numerically controlled lathe.
Background technology
Be provided with revolution hydraulic pressure tail top in Digit Control Machine Tool, in order to push against workpiece to be processed, and drive workpiece to be processed to rotate, as ball valve.Current revolution hydraulic pressure tail roof construction, it controls the tail end that the top hydraulic moving oil cylinder axially moved is arranged on tailstock top, the front end on tailstock top is provided with for pushing against the top of workpiece to be processed, top movement is driven by hydraulic moving oil cylinder, thus push against workpiece to be processed, and drive rotation to be processed, due to by hydraulic moving oil cylinder be toply all arranged on tailstock top, cause and take up room greatly, in addition, owing to being directly arranged on tailstock top by top, the supporting construction of the high rigidity of any high speed is not set on top, therefore, top when high-speed cruising, high-speed overload requirement cannot be met, be easy to damage.
Utility model content
The utility model aims to provide one and to take up room little, compact conformation, and is applicable to the revolution hydraulic pressure tail roof construction of high-speed overload requirement.
One revolution hydraulic pressure tail roof construction described in the utility model, comprise the tailstock be fixed on lathe bed, tailstock moves horizontally relatively slide mass level can run through tailstock top, slide mass one end is provided with live centre mounting groove, the other end is provided with hydraulic jack mounting groove, on the inwall of bottom land, holding tank has been dug in described hydraulic jack mounting groove, hydraulic jack stretches in hydraulic jack mounting groove, its tail end is fixed on tailstock by holder, its piston head stretches in holding tank, be provided with in described live centre mounting groove can relative sliding body rotate connecting cylinder, live centre tail end to insert in connecting cylinder and is fixed as one with it.
One revolution hydraulic pressure tail roof construction described in the utility model, man-hour need be added to workpiece, the end face that workpiece to be processed two is relative is respectively arranged with for pushing against groove that is top and live centre insertion, groove in both ends of the surface meets axiality requirement, when needing two opposing end surface of processing work, making to push against top and live centre inserts in the groove of corresponding end face respectively, and released by the piston level in the hydraulic jack in revolution hydraulic pressure tail top, promotion slide mass moves horizontally, thus slide mass drives the reach of live centre level, thus workpiece is pushed against push against top on, when needs rotational workpieces carries out turnery processing, connecting cylinder top tight workpiece is forward driven by drive unit (as motor), workpiece drives live centre to rotate together, when completion of processing, because piston head is in holding tank, the diameter of holding tank is larger than the internal diameter of hydraulic jack mounting groove, therefore, holding tank opposing hydraulic oil cylinder mounting groove inwall has chuck, thus only needs the piston reset of hydraulic control oil cylinder, and piston can drive slide mass to reset, and then slide mass drives live centre to reset, to unclamp workpiece.Because live centre and hydraulic jack are all arranged on tailstock inside, therefore, make revolution hydraulic pressure tail top overall structure compacter, take up room little.By turning round hydraulic pressure tail top and pushing against top cooperatively interacting, thus can by big and small various types of workpiece reliable grip, ensure that the precision of the processing end face that workpiece two is relative meets processing request, axiality is accurate.

Detailed description of the invention
A kind of revolution hydraulic pressure tail roof construction, as depicted in figs. 1 and 2, comprise the tailstock 2 be fixed on lathe bed 1, tailstock 2 moves horizontally relatively slide mass 3 level can run through tailstock 2 top, slide mass 3 one end is provided with live centre mounting groove, the other end is provided with hydraulic jack mounting groove, on the inwall of bottom land, holding tank has been dug in described hydraulic jack mounting groove, hydraulic jack 4 stretches in hydraulic jack mounting groove, its tail end is fixed on tailstock 2 by holder 5, its piston head 6 stretches in holding tank, be provided with in described live centre mounting groove can relative sliding body 3 rotate connecting cylinder 7, live centre 8 tail end to insert in connecting cylinder 7 and is fixed as one with it.
Be provided with double-row angular contact bal bearing 9 between described connecting cylinder 7 and slide mass 3, thus connecting cylinder 7 can rotate by relative sliding body 3 under the driving of drive unit.The axial space that double-row angular contact bal bearing 9 takies is very little, simultaneously, it can bear radial load and the axial load of high strength, the supporting rigidity of effective raising live centre 8, ensure that live centre 8 can bear axial and radial heavy load under running up, prevent live centre 8 from damaging, reduce production cost.
Thrust ball bearing 10 is provided with between described connecting cylinder 7 and slide mass 3, by arranging thrust ball bearing 10, ensure that live centre 8 top tight workpiece is more reliable, simultaneously, because thrust ball bearing 10 can bear comparatively high thrust load when running up, further increasing the ability that live centre 8 bears axial load, effectively improving the supporting rigidity of live centre 8, ensure that live centre 8 can bear axial heavy load lotus under running up, prevent live centre 8 from damaging.
Being provided with needle bearing 11 between described connecting cylinder 7 rear end and slide mass 3, by increasing needle bearing 11, further improving the radial bearing capacity of live centre 8, ensure that live centre 8 can not damage because radial load increases under running up.
Inside, described hydraulic jack 4 front end is provided with many for guiding the guidance tape 12 of piston horizontal movement, by arranging guidance tape 12, can not off-axis when ensureing piston movement, and steadily mobile.
The outer surface on described slide mass 3 top is provided with one section of groove 13, tailstock 2 is provided with the oil filler point 14 be communicated with the groove 13 on slide mass 3, by oiling in picture groove 13, thus more smooth and easy when can ensure that slide mass 3 moves axially.
Tailstock 2 is also provided with lead 15, and lead 15 is through tailstock 2, and its lower end stretches in the groove 13 on slide mass 3, and described lead 15 lower end is provided with and contacts and the roller 16 that can slide along groove-bottom with groove-bottom.When slide mass 3 moves horizontally, the degree of balance of slide mass 3 movement is controlled by lead 15, ensure that slide mass 3 can not off-axis when moving horizontally, simultaneously, by this lead 15, the stroke that further restriction slide mass 3 is movable, prevents slide mass 3 from driving live centre 8 to move forward and backward stroke excessive.
Be provided with multiple sealing ring 17 between described hydraulic jack 4 rear end and holder 5, prevent hydraulic oil in hydraulic jack 4 from releasing.
