Impurity easily pollute the brake area of brake, and then affect brake slide block and maintain slide block solid
Fixed motionless performance.
2, the apolegamy of the aspect such as its moment of torsion of brake requires height, it is difficult to meet servo-pressing machine heavy duty,
High-torque, functional reliability in high precision, under Variable Velocity Condition, owing to the installation volume of brake is big,
Affect the Appropriate application of lathe bed inner space, it addition, also find in other existing servo-pressing machine
Brake is loaded on crankshaft end, there is also drawbacks described above equally；The belt wheel of belt wheel mechanism is commonly installed
On the input shaft end of reduction box, there is cantilever position.
3, three grades of transmission band dynamic crankshafts, transmission chain length, transmission accuracy is low, kinetic equation loss is big.
4, gear shaft is laid along lathe bed depth direction, and servomotor is loaded on lathe bed bottom, and lathe bed is high
Degree space utilization is low.
Brake is the parts stopped and keeping slide block halted state that slow down for controlling slide block, even if
Servomotor under peak torque state, also should be able to brake silpper make slide block be in halted state, it
It is mainly used in following three kinds of situations:
1., when normal shutdown or improper dead electricity, maintain slide block in fixed position；2. it is used for
Brake hard is implemented, it is ensured that lathe, mould etc. are the most impaired, and are under mechanical, electrical exception or malfunction
Operator provide personal safety guarantee；The brake hard implemented in the case of 3. maloperation occurs.
China Patent No. 200520069739.4 discloses the brake dress of a kind of digital control precision shaping press
Putting, gear shaft is longitudinally arranged along lathe bed with servomotor, and gear shaft is positioned at the lower section of bent axle, this knot
The electromagnetic brake device of structure is positioned at inside lathe bed, and this gear shaft is longitudinally arranged structure and makes inside lathe bed
The utilization rate in space is low.
[utility model content]
For many technical deficiencies of above-mentioned prior art objective reality, this utility model passes through reasonable cloth
If, connect drive shaft and brake, motor, it is desirable to provide a kind of servo pressure being equipped with brake
Power machine prime drive mechanism.
To this end, this utility model following technical scheme of offer:
It is equipped with the servo-pressing machine prime drive mechanism of brake, including having driving gear and driving
Driving main gear shaft, brake and the servomotor of main shaft, servomotor is fixedly arranged on lathe bed, drives
Main axis is arranged on lathe bed, and its improvement is: described drive shaft is by the left and right side of lathe bed
To in lateral arrangement, and the axle stretch end of one end of drive shaft and servomotor is rigidly connected, and drives
The other end of main shaft stretches out outside lathe bed and is rigidly connected with brake, and it is main that described driving gear is positioned at driving
Between the two ends of axle.
In order to optimize the layout of this prime drive mechanism, its installation of the above-mentioned drive shaft in lateral arrangement
Position is at the rear upper of lathe bed, and so, the lathe bed front upper space vacateed can be as installation
Used by the space of bent axle, be installed on bent axle, gear wheel that volume exclusion is bigger can correspondingly be arranged
In the front upper (i.e. driving the dead ahead of gear) of lathe bed, and with drive the driving tooth of main gear shaft
Wheel is meshed, and so, the space of lathe bed front upper obtains sufficiently effective utilization, can make
Longitudinal degree of depth of the forward and backward lathe bed of servo-pressing machine is greatly collapsed into possibility.
As preferentially, above-mentioned axle stretch end is provided with the first expansion sleeve, and one end of described drive shaft is provided with even
Female connector, and its other end is provided with the second expansion sleeve, the first expansion sleeve is placed in adapter sleeve, the second tensioner
It is placed in the center mounting hole of brake.
One end of drive shaft is that inside and outside spline couples with above-mentioned axle stretch end, the other end of drive shaft
With brake by key connecting, or one end of drive shaft is coupled by shaft coupling with above-mentioned axle stretch end,
Key connecting is passed through in the other end of drive shaft and brake.
As preferentially, above-mentioned driving gear and drive shaft are two-in-one single part.
In drive shaft, straight forming drives gear, and single component machining accuracy concordance is high, drives
Gear can exempt to offer axis hole, exempt to press-fit, and part bulk strength is high, transmission accuracy is high；Drive gear master
Axle realizes whole tearing open self-contained, and maintenance is changed quick.
Above-mentioned brake is electricity loss brake.
This utility model fact has the advantage that and beneficial effect:
1, brake is positioned at outside lathe bed, can noiseless demolition, installation, it is simple to repair and maintenance operation, it is to avoid lubrication
In agent, impurity pollutes the brake area of brake, it is ensured that brake silpper and make slide block be in halted state.
2, brake is laid in drive shaft and stretches out the outer end of lathe bed with this axle and is connected, and this is with often
See that brake is loaded on the output shaft of reduction box or is loaded on bent axle to compare, be substantially reduced brake
Apolegamy requirement, the torque demand of brake is expected to reduce by 3～10 times, correspondingly achieves brake little
Type, and servo-pressing machine can be met again in heavy duty, high-torque, work in high precision, under Variable Velocity Condition
Make reliability.
3, drive gear between the drive shaft two ends of lateral arrangement, can avoid driving gear to be in
Under cantilever position, engagement drives gear wheel, not only can make to drive main gear shaft revolution steadily, Er Qieyou
Beneficially the reasonable Arrangement of lathe bed internal drive mechanism, reduces lathe bed size.
4, servomotor directly is rigidly connected to achieve with driving main gear shaft and directly drives, and is thus greatly promoted
Drive efficiency, after this utility model prime drive mechanism is assembled on known forcing press, drives
Gear can be used for directly engaging the gear wheel that driving is fixedly arranged in crankshaft end, it is achieved thereby that one-level passes
Dynamic, therefore servo-pressing machine can realize the design of one-level big speed ratio, driving-chain is short, compact conformation thus
Efficiency is high, and the stability for subsequent motion transmission lays a solid foundation.
5, the two ends of main gear shaft are driven to be rigidly connected with servomotor, brake respectively, this measure
Transmission accuracy height, kinetic equation loss can be made little.
