Abstract
The utility model relates to a hydraulic composite cylinder structure of a machine tool tailstock, which comprises an oil inlet, an end cover, a coupling screw, a tailstock sleeve, a wear-resistant sleeve, an intermediate core shaft, an anti-rotation screw, a rotating top tip component, a buffer ring, a block plug and the like. The tailstock sleeve reciprocates in a tailstock body and is matched with the inner hole of the tailstock body to form a hydraulic control ejection cylinder, and the wear-resistant sleeve and the intermediate core shaft are embedded in the tailstock sleeve to form a hydraulic cylinder for ejection and rapid withdrawal. Supply of pre-tightening hydraulic pressure is realized through a main oil inlet on the end cover, and supply of auxiliary hydraulic pressure for pre-tightening force and supply of hydraulic pressure for rapid withdrawal of the tailstock sleeve are realized through the oil inlet and an oil return port connected with the intermediate core shaft. The tailstock sleeve is used for supporting the rotating top tip and making the tailstock prop against the piston part of the hydraulic cylinder; and the intermediate core shaft also serves as a piston of the hydraulic cylinder in the tailstock sleeve. The reciprocating cylinder is hidden in the tailstock sleeve, and thus the space occupied by the tailstock is saved.
Description
Technical field
The utility model relates to the top structure that holds out against of a kind of tail stock for machine tool, belongs to the mechanical-hydraulic compound gearing, is mainly used in top effect of holding out against of tail stock for machine tool and pressure adjustment.
Background technology
Hold out against in the motion in that tail stock for machine tool is top; The a kind of of employing is the manual control frame mode at present; Promptly device has T type feed screw nut drive mechanism on tailstock; Manually control is assemblied in the handwheel on the screw mandrel, utilizes feed screw nut's self-locking to reach the effect that holds out against to workpiece, and the size of pressure depends on operator's feel; The another kind mode is to adopt hydraulic principle control, on tailstock, connects the hydraulic jack of single piston reciprocating type, and holding out against of tailstock center unclamped by oil cylinder reciprocating motion realization, and the size of pressure then changes control through the pressure of hydraulic system.In above-mentioned two kinds of technology, mode one is unfavorable for realizing controlling automatically and pressure is accurately adjusted; Second way oil cylinder and tailstock form cascaded structure, and it is big to occupy the space, is unfavorable for the integral layout of lathe.
Summary of the invention
For better reciprocating motion and the pressure control that realizes that tail stock for machine tool is top; Dwindle and occupy the space; The utility model provide a kind of rational in infrastructure, be easy to make, the tail stock for machine tool hydraulic pressure composite oil cylinder structure of handiness; This hydraulic pressure composite oil cylinder structure can realize reciprocating motion and the pressure control of tailstock center, and hydraulic jack is built-in layout, and it is little to occupy the space.
The technical scheme of the utility model is: be used for the hydraulic pressure composite oil cylinder structure of tail stock for machine tool, comprise oil-in, end cap, joint bolt, tailstock, wear-resistant sleeve, middle mandrel, anti-turn screw, live centre assembly, bumper ring, obstruction.Described live centre assembly is arranged in the tailstock, toply can pull down replacing from front end; Described tailstock moves back and forth in tailstock body, and sleeve cooperates the stretch oil cylinder that forms hydraulic control with the tailstock body endoporus, in tailstock, holds out against and rewind down effect hydraulic jack through inlaying wear-resistant sleeve and middle mandrel composition.All be designed with sealing ring between all movement parts, cylinder body and end cover.Main oil-in is realized the hydraulic coupling supply of pressure, and the oil-in that links to each other with middle mandrel, oil return opening are realized the auxiliary hydraulic pressure power supply of pressure and the rewind down hydraulic coupling supply of tailstock.
During application; Hydraulic oil gets in the cavity of tailstock body, tailstock, the formation of interior outer end cap through oil-in; Pressure oil promotes tailstock and advances; At this moment, another oil-in is squeezed into pressure oil tailstock, middle mandrel, is stopped up in the cavity that forms simultaneously through the oilhole in the middle mandrel, promotes advancing of tailstock equally; The size of tailstock pressure can change through two group oil cylinder hydraulic pressures and realizes.When tailstock need be retreated, two groups of oil-in hydraulic pressures in the time of will advancing were adjusted to oil return opening through reversal valve, and the annular chamber hydraulic fluid port of middle mandrel is injected hydraulic pressure oil, and tailstock is accomplished rapid-return motion.
Tailstock in the hydraulic pressure composite oil cylinder structure of the tail stock for machine tool described in the utility model is the top part of bearing and turning, is again to realize that tailstock holds out against the piston details of middle hydraulic jack; Mandrel one end is fixed through joint bolt and tailstock end end cap in the middle of described; The other end is then made the piston of hydraulic jack in the tailstock; The composite oil cylinder structure of the utility model design is the reciprocating oil cylinder is hidden in the inside of tailstock, and main pressure oil cylinder is then realized through tailstock self.Greatly save tailstock and occupied the space.
