As machining center electro spindle develops to high speed, efficient and high-precision direction, its reliability level turns into restriction and added
The main bottleneck of work center electro spindle development.At present, improving the method for machining center electro spindle reliability mainly has selection suitable
High-speed bearing, lubrication reasonable in design and cooling system, enter action balance to each rotary part, be assemblied in all revolving mebers
Whole dynamic balance is carried out on main shaft, mainly balancing loop is installed additional, from the aspect of structure design using two ends in structure design
Dynamic and thermal characteristic of electro spindle etc..However, all these methods do not consider electro spindle from the use process of electro spindle
Integrity problem.
Because electro spindle rotating speed is high, any amount of unbalance can all cause the generation of vibration.Although electro spindle design and
The problem of vibration is present is considered in manufacturing process, and relevant issues are improved, but electro spindle is in use,
There are still vibration problem caused by external factor.When cutter dynamic balancing is bad, cutting parameter is unreasonable or lathe hit etc. feelings
When condition occurs, electro spindle will produce a certain degree of vibration, and this may produce a certain degree of damage to cutter and electro spindle.
Based on this case, a monitoring modular is designed, the phenomenon is fed back in time, contribute to lathe to alarm shutdown immediately to protect
Cutter and electro spindle.
The content of the invention
In order to solve the above problems, the present invention provides a kind of electro spindle acceleration vibration monitoring module, and electro spindle is made
Vibration during is monitored, and this can be effectively by cutter dynamic balancing is bad, cutting parameter is unreasonable or lathe hits etc.
Caused oscillation phenomenon is fed back in time, reaches that lathe is alarmed the purpose of shutdown immediately, so as to protect cutter and electro spindle, is carried
The reliability and service life of high electro spindle.
To achieve these goals, the technical solution adopted by the present invention is：A kind of electro spindle acceleration vibration monitoring mould
Block, including spindle rotor and cutter, spindle rotor are arranged on cutter top, and spindle rotor is provided with front-end bearing pedestal, and bearing is set
Between spindle rotor and front-end bearing pedestal, one end of front-end bearing pedestal is provided with acceleration type vibrating sensor, vibration sensor signal
One end connection acceleration type vibrating sensor of line, the other end connecting machine tool control system of vibration sensor signal line.
Preferably, the acceleration type vibrating sensor is fixedly mounted in front-end bearing pedestal.
Any of the above-described scheme is preferably, and the acceleration type vibrating sensor is fixedly mounted on front-end bearing pedestal by screw
It is interior.
Any of the above-described scheme is preferably, and the outside of the acceleration type vibrating sensor is provided with pressing plate.
Any of the above-described scheme is preferably, and the pressing plate is fixedly connected on the side of front-end bearing pedestal.
Any of the above-described scheme is preferably, and the pressing plate is fixedly connected on the side of front-end bearing pedestal by sunk screw.
The beneficial effects of the invention are as follows：The present invention provides a kind of electro spindle acceleration vibration monitoring module, to electro spindle
Real-time online vibration in the course of work is monitored, by cutter dynamic balancing is bad, cutting parameter is unreasonable or lathe hits etc.
Caused oscillation phenomenon carries out feeding back to machine tool control system in time, when the vibration values for electro spindle occur exceed machine tool control system
During set vibration safety scope, lathe will alarm shutdown immediately, so as to protect cutter and electro spindle, and that improves electro spindle can
By property and service life.
