Abstract

The invention discloses a kind of novel hydraulic tailstock brake structure, the brake structure be by slide of tail stock bottom, brake shoes, piston, braking vane, spring, O-ring, tailstock guide, silently, nuts and bolt forms;It is bolted to connection between the top of the slide of tail stock bottom and brake shoes, the bolt is fixed on slide of tail stock bottom by supporting nut, and lower end is connected with brake shoes;Spring is additionally provided between the slide of tail stock bottom and brake shoes, the spring set upper side, which has, silently to be fixed, and the bottom of the brake shoes is fixedly connected with braking vane, and some pieces of pistons are distributed with the braking vane, and O-ring is cased with each piston;The tailstock guide in lathe bed uses dovetail groove type hard rail structure, and the slide of tail stock bottom is fixedly mounted on tailstock guide.Structure of the present invention is bigger than the coupling mechanism force of conventional tailstock brake structure, because contact is contact of the face with face, required cost ratio is lower using oil hydraulic cylinder brake, more reliable.

Description

A kind of novel hydraulic tailstock brake structure
Technical field
The invention belongs to numerical-control horizontal lathe field, and in particular to a kind of novel hydraulic tailstock brake structure, for tailstock The brake of bottom plate.
Background technology
Today's numerical control lathe tailstock brake generally use manually or hydraulic locking mode.Hand in use, need Worker manually adjusts tailstock position, then clamping screw, using trouble, laborious.Hydraulic locking, be buying or self-control small oil tank Guide rail is held out against so as to reach locking purpose, but oil cylinder piston and guide rail contacting surface are small, and tailstock coupling mechanism force is limited.
The content of the invention
Goal of the invention:In order to solve the deficiencies in the prior art, the invention provides a kind of novel hydraulic tailstock brake structure. The purpose of this patent is to make that tailstock brake lining is bigger, and coupling mechanism force is bigger, is applicable the big application of tailstock pressure, as end face drives turning Irregular pole, massive workpiece etc..
Technical scheme:A kind of novel hydraulic tailstock brake structure, the brake structure are by slide of tail stock bottom, brake shoes, work Plug, braking vane, spring, O-ring, tailstock guide, silently, nuts and bolt form;
It is bolted to connection between the top of the slide of tail stock bottom and brake shoes, the bolt passes through supporting nut It is fixed on slide of tail stock bottom, lower end is connected with brake shoes;Spring, the spring are additionally provided between the slide of tail stock bottom and brake shoes Set upper side, which has, silently to be fixed;
The bottom of the brake shoes is fixedly connected with braking vane, and some pieces of pistons, Mei Gesuo are distributed with the braking vane State and O-ring is cased with piston;
The tailstock guide in lathe bed uses dovetail groove type hard rail structure, and the slide of tail stock bottom is fixedly mounted on tailstock and led On rail.
As optimization:The number of the piston is 13.
As optimization:The number silently is 2, is symmetrically distributed in the left and right ends of slide of tail stock bottom.
As optimization:The number of the spring is 2, is symmetrically distributed in the left and right ends of slide of tail stock bottom.
Beneficial effect:Structure of the present invention is bigger than the coupling mechanism force of conventional tailstock brake structure, because contact is connecing for face and face Touch, required cost ratio is lower using oil hydraulic cylinder brake, more reliable.

Fig. 2 is the sectional perspective structural representation of the present invention;
Fig. 3 is the cross-sectional view of the present invention;
Fig. 4 is the side structure schematic view of the present invention;

Embodiment
Embodiment
As shown in figures 1 to 6, a kind of novel hydraulic tailstock brake structure, the brake structure are by slide of tail stock bottom 1, brake shoes 2nd, piston 3, braking vane 4, spring 5, O-ring 6, tailstock guide 7, silently 8, nut 9 and bolt 10 are formed.
It is fixedly connected between the slide of tail stock bottom 1 and the top of brake shoes 2 by bolt 10, the bolt 10 is by supporting Nut 9 be fixed on slide of tail stock bottom 1, lower end is connected with brake shoes 2;Bullet is additionally provided between the slide of tail stock bottom 1 and brake shoes 2 Spring 5, the spring set upper side, which has, silently 8 to be fixed;It is described silently 8 number be 2, be symmetrically distributed in the left and right of slide of tail stock bottom 1 Both ends.The number of the spring 5 is 2, is symmetrically distributed in the left and right ends of slide of tail stock bottom 1.
The bottom of the brake shoes 2 is fixedly connected with braking vane 4, some pieces of pistons 3 is distributed with the braking vane 4, often O-ring 6 is cased with the individual piston 3.The number of the piston 3 is 13.
Wherein, the tailstock guide 7 in lathe bed uses dovetail groove type hard rail structure, and slide of tail stock bottom 1 is fixedly mounted on tailstock and led After rail 7, hydraulic oil enters in brake shoes 2, and 13 pieces of pistons 3 are jacked up, make the inclined-plane of brake shoes and lathe bed dovetail groove inclined-plane sturdy, So as to check tailstock.When oil pressure loses, in the presence of 2 springs 5, brake shoes playback, tailstock loosens.
Structure of the present invention is bigger than the coupling mechanism force of conventional tailstock brake structure because contact be contact of the face with face, it is required into This is lower than being braked using oil hydraulic cylinder, more reliable.
Technical scheme in the embodiment of the present invention is clearly and completely described the above, so that the skill of this area Art personnel can be better understood from advantages and features of the invention, so as to make apparent boundary to protection scope of the present invention It is fixed.Embodiment described in the invention is only part of the embodiment of the present invention, rather than whole embodiments, based on the present invention In embodiment, the every other implementation that those of ordinary skill in the art are obtained on the premise of creative work is not made Example, belongs to the scope of protection of the invention.
