Ring lathe quick-replaceable stage property, and the stability for lathe work has a certain impact, existing spindle braking system, system
Flowing mode is single, and service life is short, and braking effect is unstable, and lathe also can produce loss；Therefore it provides a kind of structure is closed
Reason, easy and simple to handle, brake main shaft Quick-speed braking arrangement quick, good in economic efficiency, length in service life and be necessary.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and provide a kind of rational in infrastructure, easy and simple to handle,
Brake quick, good in economic efficiency, the main shaft Quick-speed braking arrangement of length in service life.
The purpose of this utility model is achieved in that a kind of main shaft Quick-speed braking arrangement, and it includes main spindle box, described
The middle part of main spindle box is provided with main shaft, and described main shaft is provided with brake disc A, and the outside of described brake disc A is uniformly arranged
Having teeth A, the lower section of described brake disc A to be provided with brake block, the upside of described brake block is provided with teeth B, described
The downside of brake block connects electric pushrod, and described electric pushrod connects chronotron, and described chronotron connects control
Device, the right of described brake disc A is provided with brake disc B, and the lower section of described brake disc B is provided with brake shoes, and described stops
The lower right side of car block connects has piston rod, the right side of described piston rod to be provided with hydraulic cylinder.
The quantity of described teeth A is 25-35.
The quantity of described teeth B is 3.
Described controller is PLC.
Described brake shoes is concave shape brake shoes.
Described hydraulic cylinder is double acting hydraulic cylinder.
The beneficial effects of the utility model: this utility model uses brake disc A and brake disc B, in use, works as master
After spindle motor power-off, hydraulic cylinder action promotes piston rod so that brake shoes rubs with brake disc B so that the speed of mainshaft is fast
Prompt drop is low, and controller controls electric pushrod action simultaneously so that arrange outside teeth B arranged on brake block and brake disc A
Teeth A contact so that main shaft stops completely, owing to have employed chronotron so that after brake disc B produces reduction of speed effect with brake shoes
The a bit of time, brake block just produces directly braking to brake disc A, and whole braking procedure is rationally quick, is reducing rapidly master
While axle speed, the service life of whole brake unit is the longest, good in economic efficiency；This utility model have rational in infrastructure,
Easy and simple to handle, brake quick, good in economic efficiency, the advantage of length in service life.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model a kind of main shaft Quick-speed braking arrangement.
Fig. 2 is the partial structurtes schematic diagram of this utility model a kind of main shaft Quick-speed braking arrangement.
In figure: 1, main spindle box 2, brake disc A 3, brake disc B 4, main shaft 5, piston rod 6, hydraulic cylinder 7, stop
