Description
Technical field
The utility model provides a kind of vibration tail stock, and it is parts of lathe, and top or cutter can be installed, in order to hold out against or processing work.
Background technology
The traditional lathe tailstock, can be in the tailstock sleeve mounting cutter, as drill bit, hand feed, but borehole accuracy is low, rough surface, the about IT13-IT11 of dimensional accuracy, the about Ra50-12.5 μ of surface roughness m.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point and a kind of vibration tail stock is provided, it makes the drill bit that is installed on the tailstock produce an axial vibration simultaneously in working angles, can improve borehole accuracy and efficient, can hole on the difficult to machine material at the hardness height.
The purpose of this utility model is achieved in that the vibration tail stock is to install hydraulic vibration device on tail stock additional, and hydraulic vibration device contains Hydraulic Station, reversal valve, oil cylinder, motor.Oil cylinder is fixedly connected at the rear portion of tailstock body, and Hydraulic Station and reversal valve link, and reversal valve and oil cylinder link, and piston can move axially in oil cylinder, the piston rod that stretch out at the piston two ends, and an end and screw mandrel link, and can adorn handwheel on the other end.Reversal valve contains valve seat, spool, and the end axle of spool links by driving member and the motor that is contained on the tailstock body.During cutting, the driven by motor valve core rotation, hydraulic oil enters oil cylinder by Hydraulic Station output through reversal valve, makes piston produce axial vibration.
Advantage of the present utility model is novel, can realize vibrocutting, and effect is remarkable.As boring, in traditional boring procedure, add vibration, can improve borehole accuracy and reduce surface roughness, dimensional accuracy can reach IT8-1T6, and rough surface makes and can reach Ra6.3-0.8 μ m.Can reduce cutting force, heat in metal cutting improves stock-removing efficiency, improves the service life of drill bit.Can bore aperture on the difficult to machine material at the hardness height, as heat resisting steel, pottery etc.
Description of drawings

Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
In conjunction with the accompanying drawings, embodiment of the present utility model is described further.The vibration tail stock is to install hydraulic vibration device on tail stock additional, and it contains tailstock body 1, tailstock sleeve 2, screw mandrel 3 and hydraulic vibration device, and hydraulic vibration device contains Hydraulic Station 10, reversal valve, oil cylinder 7, piston 8, motor 4.Oil cylinder includes drive end bearing bracket, rear end cap and cylinder body, and cylinder body is positioned at the centre of forward and backward end cap, with screw oil cylinder is fixedly connected at the rear portion of tailstock body.Hydraulic Station and reversal valve link.Reversal valve and oil cylinder link, and are screwed connection.Piston can move axially in oil cylinder, the piston rod that stretch out at the piston two ends, and an end and screw mandrel link by bearing pin 9, can adorn handwheel on the other end, and reversal valve contains valve seat 5, spool 6, and the end axle of spool links by belt transmission and the motor that is contained on the tailstock body.During cutting, drill bit is packed in the tailstock sleeve, the driven by motor valve core rotation, hydraulic oil enters oil cylinder by Hydraulic Station output through reversal valve, makes piston produce axial vibration, realizes vibrocutting, and it is constant to keep the tailstock original function simultaneously.Present embodiment, motor is the frequency-adjustable speed-adjustable motor, is outsourcing piece.Hydraulic Station also is an outsourcing piece, and it can move with tailstock on the other rail of dividing into of lathe.
Reversal valve is a rotary valve, on spool, the valve seat oil duct is arranged, and the oil duct on the valve seat communicates with oil duct on the oil cylinder.The vibration of piston is to produce like this: driven by motor valve core rotation, spool when oil duct on the valve seat communicates, oil cylinder one end oil-feed, the other end is fuel-displaced, flows back to fuel tank through reversal valve, piston moves; Otherwise piston then oppositely moves; Forward and reverse so fast moving produces vibration.The vibration of piston drives drill vibration by screw mandrel and tailstock sleeve.The frequency and the amplitude of vibration are adjustable, decide according to processing work, and machining bearing steel workpiece for example, bore diameter is 6mm, and frequency is 100 hertz, and amplitude is 0.02mm, and dimensional accuracy reaches IT8, surface roughness Ra 3.2-1.6 μ m.The method that vibration frequency and amplitude are regulated is: the rotating speed of regulating reversal valve can regulating frequency, regulates the flow of overflow valve, choke valve in the Hydraulic Station and can regulate amplitude.
