Abstract

A hydraulic elastic sleeve type tailstock comprises a tailstock body; a sleeve is arranged in the tailstock body; a top spindle is mounted in the sleeve through a bearing; a horizontal mounting hole is formed on the tailstock body; a left clamping block and a right clamping block which are symmetrical are arranged in the mounting hole; the left clamping block and the right clamping block are provided with cylindrical surfaces which are matched with the outside surface of the sleeve; the left clamping block and the right clamping block are provided with axial central holes; a connecting rod is arranged in the central holes; the right end of the connecting rod is fixedly connected with the right clamping block; the left end of the connecting rod is connected with a piston; an oil cylinder matched with the piston is fixedly connected with the left end of the left clamping block; a bellevill spring is arranged between the piston and the left end of the left clamping block; and an oil cavity on the left side of the piston is communicated with a pipe joint mounted on the end of the oil cylinder. After installation, because of the action of the bellevill spring, the left clamping block and the right clamping block clamp the sleeve oppositely, and oil is supplied to the oil cavity through a hydraulic device; the bellevill spring is compressed, and the left clamping block and the right clamping block loosen the sleeve oppositely; the sleeve can be clamped and loosened without the need of manual operation, so that the action is flexible and reliable.

Description

Hydraulic pressure elastic cover cartridge type tailstock
Technical field
The utility model relates to a kind of tailstock, particularly a kind of hydraulic pressure elastic cover cartridge type tailstock that is applicable to the large-sized numerical control lathe.
Background technology
Sleeve and the locking between the tailstock in the existing large-sized numerical control tail stock or unclamp by the operator and manually carry out, when the lathe specification increased, tailstock will correspondingly increase, and caused the manual locking operating difficulties, and increase operator's working strength wastes time and energy.
Summary of the invention
The purpose of this utility model provide a kind of simple in structure, flexible movements reliable, need not manually operated hydraulic pressure elastic cover cartridge type tailstock.
Hydraulic pressure elastic cover cartridge type tailstock of the present utility model, comprise tailstock body, be provided with sleeve in the tailstock body inboard, by bearing top main shaft is installed in the sleeve, horizontal installing hole is arranged above tailstock body, be provided with the left fixture block and the right fixture block of symmetry in installing hole, left fixture block and right fixture block are provided with cylinder and the sleeve outer surface matches; Left side fixture block and right fixture block have axial center hole, be provided with connecting rod in this centre bore, fixedly connected between the right-hand member of connecting rod and the right fixture block, the left end and the piston of connecting rod join, fixedly connected with the left end of left fixture block with the oil cylinder that piston matches, be provided with the butterfly spring between the left end head of piston and left fixture block, the oil pocket in piston left side is connected with the pipe joint that is installed in the oil cylinder termination.
Hydraulic pressure elastic cover cartridge type tailstock of the present utility model, the right-hand member of wherein said right fixture block has right end cap to fixedly connected with tailstock body, between the right-hand member head of connecting rod and the right end cap gap, right side is arranged; The left end of oil cylinder has pressure ring to fixedly connected with tailstock body, and the gap, left side is arranged between pressure ring and the oil cylinder.
Hydraulic pressure elastic cover cartridge type tailstock of the present utility model, after the installation, because the effect of butterfly spring, make the relative closing sleeve of left fixture block with right fixture block, make relative fixed between sleeve and the tailstock body, unclamp sleeve as needs, by hydraulic means fuel feeding in oil pocket, piston moves in oil cylinder, this moment, the butterfly spring was compressed, the left side fixture block relative certain distance that leaves with right fixture block makes left fixture block and right fixture block unclamp sleeve simultaneously, and the clamping of sleeve need not manual operation with unclamping, time saving and energy saving, overall structure is simple, and is easy to operate, and flexible movements are reliable.
Description of drawings
Fig. 1 is the structural representation of the utility model specific embodiment.
The specific embodiment
As shown in Figure 1: 13 is tailstock body, in the inboard of tailstock body 13 sleeve 2 is housed, and sleeve 2 inboards are equipped with tailstock main shaft 1 by bearing.Above tailstock body 13, laterally be processed with installing hole, the left fixture block 10 and the right fixture block 12 of symmetry is housed in this installing hole.Be processed with cylinder below the opposite end on a left side fixture block 10 and the right fixture block 12 and sleeve 2 outer surfaces match.
Left side fixture block 10 and right fixture block 12 all have axial center hole, be provided with connecting rod 11 in this centre bore, fixedly connected between the right-hand member of connecting rod 11 and the right fixture block 12, fixed form is to be inserted with limited block 14 on right fixture block 12, limited block 14 just is inserted in the radial slot on the connecting rod 11, makes extension bar 11 fixing with respect to right fixture block 12.The right-hand member of right fixture block 12 has right end cap 15 and tailstock body 13 to be bolted to connection, and leaves gap, right side 16 between the right-hand member head of connecting rod 11 and the right end cap 15.
Be threaded between the left end of connecting rod 11 and the piston 8, the oil cylinder 5 that matches with piston 8 is bolted to connection with the left end of left fixture block 10, between the left end of piston 8 and left fixture block 10, be set with butterfly spring 9, form oil pocket 7 in the piston 8 left side oil cylinders 5, oil pocket is connected with the pipe joint 4 that is installed in oil cylinder 5 terminations.The left end of oil cylinder 5 has pressure ring 3, is bolted to connection between pressure ring 3 and the tailstock body 13, leaves gap 6, left side between pressure ring 3 and oil cylinder 5 left ends.
After this tailstock is installed, because the effect of butterfly spring 9, make left fixture block 10 and right fixture block 12 relative closing sleeves 2, make relative fixed between sleeve 2 and the tailstock body 13, unclamp sleeve 2 as needs, by hydraulic means through pipe joint 4 fuel feeding in oil pocket 7, piston 8 moves in oil cylinder 5, butterfly spring 9 is compressed at this moment, and left fixture block 10 and the right fixture block 12 relative certain distances that leave make left fixture block 10 and right fixture block 12 unclamp sleeve 2 simultaneously.
