Description
Technical field
The invention belongs to braking technology field, and in particular to a kind of brake apparatus, more particularly to a kind of main shaft fast braking
Device.
Background technology
Lathe is to be machined the common universal machine of factory, and spindle braking system used on machine tool is mostly logical
Mechanical brake or fluid brake, complex structure, troublesome poeration are crossed, and is difficult to automatically control, main shaft is in spindle motor
After power-off, because the inertia of main shaft can not cause that main shaft quickly stops operating, it has the disadvantage that workpiece can not quickly stop operating, shadow
Lathe quick-replaceable stage property is rung, and is had a certain impact for the stability that lathe works, existing spindle braking system, system
Flowing mode is single, and service life is short, and braking effect is unstable, and loss can be also produced to lathe；Therefore it provides a kind of structure is closed
Reason, easy to operate, quick, good in economic efficiency, long service life the main shaft Quick-speed braking arrangement of braking are necessary.
The content of the invention
The invention aims to overcome the deficiencies in the prior art, and provide a kind of rational in infrastructure, easy to operate, braking
Quickly, good in economic efficiency, long service life main shaft Quick-speed braking arrangement.
The object of the present invention is achieved like this：A kind of main shaft Quick-speed braking arrangement, it includes main spindle box, described main shaft
Main shaft is provided with the middle part of case, brake disc A is provided with described main shaft, be uniformly arranged on the outside of described brake disc A with teeth
Tooth A, is provided with brake block below described brake disc A, teeth B, described braking are provided with the upside of described brake block
Electric pushrod is connected with the downside of block, described electric pushrod is connected with delayer, and described delayer is connected with controller, institute
The right of the brake disc A for stating is provided with brake disc B, is provided with brake shoes below described brake disc B, described brake shoes
Lower right side is connected with piston rod, and hydraulic cylinder is provided with the right side of described piston rod.
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.
Beneficial effects of the present invention：The present invention uses brake disc A and brake disc B, in use, when spindle motor is disconnected
After electricity, hydraulic cylinder action promotes piston rod so that brake shoes is rubbed with brake disc B so that the speed of mainshaft is reduced rapidly, together
When controller control electric pushrod action so that the teeth A of teeth B and brake disc A the outside setting set on brake block is contacted,
So that main shaft stops completely, as a result of delayer so that when a bit of after brake disc B and brake shoes generation reduction of speed effect
Between, brake block is just to brake disc A generations directly braking, and whole braking procedure is rationally quick, in rapid reduction spindle speed
Meanwhile, the service life of whole brake apparatus is also more long, good in economic efficiency；The present invention has rational in infrastructure, easy to operate, braking
Quickly, good in economic efficiency, long service life advantage.
