Description
Technical field
The invention belongs in a kind of lathe stop mechanism, particularly a kind of engine lathe the device controlling main shaft and stop.
Background technology
At machine industry, engine lathe uses the common electric machine of single rotating speed, when machine tool chief axis needs to stop operating, electric part has a button, press stop button mair motor can stop operating, but because the principal axis of inertia can not stop the rotation at once, so need to adopt a kind of brake structure, when mair motor stops operating, main shaft also will stop operating at once, the brake structure operation principle of the existing use of the industry is as follows: when mair motor stops operating, shift fork drives guide pad motion, guide pad drives a rotating shaft, and transmission levers is rotated, and then make friction belt hold brake wheel tightly, whole machine tool chief axis is stopped operating.This nested structure shortcoming is as follows: 1. driving-chain is complicated, and part is many, and process and assemble workload is large, very easily causes brake failure.2. brake weight is artificial adjustment, if tuned up, brake ribbon is tight, and frictional force is large; Caloric value is large; Easily burn part.3. friction belt is easy to wear, needs often to change, and brake just arrives the life-span 10,000 times usually, needs to change.
Summary of the invention
The object of this invention is to provide a kind of effective engine lathe brake gear, this apparatus structure is simple, and save space, brake travel is fixed, accurate and flexible, and device is wear-resisting durable, easy to adjust, and production cost and maintenance cost are reduced all greatly.
The object of the invention is to be realized by following technology: it comprises lathe housing, brake lever, it is characterized in that: connect braking mechanism at lathe housing, braking mechanism structure is as follows: connection rotating shaft on lathe housing, and one end of rotating shaft is fixedly connected with brake lever, the other end stationary cam of rotating shaft; In fixing sliding sleeve, install push rod, lower end and the cam of push rod keep in touch state; The support member of lathe housing connects connecting rod by axle, connecting rod end thereof contacts push rod upper end; Braking mechanism housing installs lower push rod, and lower push rod upper end arranges screw thread and passes the other end of connecting rod, is connected by nut; Be positioned at the lower push rod top assembling back-moving spring outside braking mechanism housing; The lower end of lower push rod is fixedly connected with brake disc top cover; Machine Tool Main Drive axle upper end is fixedly connected with brake block inner sleeve, puts the multiple dynamic brake block of suit in the brake block with axial limiting groove; In the periphery of inner sleeve, i.e. fixing assembling brake gear housing on lathe housing, brake gear housing has axial location groove, multi-disc is determined brake block and is inserted axial location groove location by positioning convex on periphery, determine brake block and dynamic brake block is interspersed is arranged alternately.
Good effect of the present invention: 1, structure is simple; 2, save space, taking of space is far smaller than original brake structure, and not be used in slot milling on axle and install brake wheel, this device is arranged on axle head, and other modular constructions also all extremely simply save space greatly; 3, brake travel fix, accurate and flexible, brake gear is all that " firmly " connects, namely the brake ribbon in similar conventional brake device is not had, position can not be fixed, there is spring on this brake gear braking top top, can playback in time when not pulling brake lever, stroke is the most short contact distance of cam and connecting rod to longest distance; 4, wear-resisting durable, the brake gear of tradition engine lathe mainly realizes brake function by friction belt and brake wheel friction, generate heat in friction belt and brake wheel friction process large especially, wearing and tearing nature is also very large, what this device adopted is the multi-disc friction sheet of spring steel material, compared with traditional friction belt brake wheel, be that heating or wearing and tearing are all much smaller; 5, easy to adjust, if the braking time of main shaft will be adjusted, the nut of 3-linkage only need be adjusted.

Detailed description of the invention
See Fig. 1-4, concrete structure is as follows: on lathe housing 6, be connected by screw braking mechanism, braking mechanism structure is as follows: connection rotating shaft 2 on the support member 3 of lathe housing 6, and one end of rotating shaft 2 is fixedly connected with brake lever 23, and the other end of rotating shaft 2 is by trip bolt 1 stationary cam 4; Lathe housing 6 is fixed sliding sleeve 8, installs push rod 5 in sliding sleeve 8, lower end and the cam 4 of push rod 5 keep in touch state, and the beeline that push rod 5 lower end contacts with cam 4 is the stroke of brake to longest distance; Lathe housing 6 connects support member 11 and braking mechanism housing 10, support member 11 connects connecting rod 12 by axle 13, connecting rod 12 end thereof contacts push rod 5 upper end; Braking mechanism housing 10 installs lower push rod 15, and lower push rod 15 upper end arranges screw thread and passes the other end of connecting rod 12, is connected by nut; Be positioned at the lower push rod 15 top assembling back-moving spring 16 outside braking mechanism housing 10, lower push rod 15 top fixing spring card 14; The lower end of lower push rod 15 is fixedly connected with brake disc top cover 17.Machine tool chief axis 22 is assembled on lathe housing 6 by bearing 21, and machine tool chief axis 22 upper end is fixedly connected with brake block inner sleeve 19 by screw 7 with compressing tablet 9 and connecting key, is set with 5 dynamic brake block 18-1 with in the brake block inner sleeve 19 of circumferential stopper slot; In the periphery of inner sleeve 19, i.e. fixing assembling brake gear housing 20 on lathe housing 6, brake gear housing 20 has axial location groove, determine brake block 18-2 for 6 and insert axial location groove location by the positioning convex on periphery, determine brake block 18-2 and dynamic brake block 18-1 interval is arranged, form brake(-holder) block assembly 18.
The course of work:
Brake lever 23 is pulled during brake, drive the rotating shaft 2 be connected with cam 4, cam 4 is rotated, cam makes push rod 5 move up when rotating, and push rod 5 makes linkage right-hand member to pressing down, and brake block push rod 15 moves down under the effect of linkage, move brake block and determine brake block and compress, start brake, several seconds rear axle stops operating, and completes a brake process.At the back-moving spring 16 of brake block top cover upper end, brake block lower push rod 15 is resetted during releasing of brake handle 23, whole device gets back to origin-location.
