Summary of the invention
To solve the problems, such as that, in the prior art using nitrogen balance systematic influence lathe for machining machining accuracy, the present invention provides
A kind of machine ram balancing device, the purpose of realization are that the balancing device can substantially reduce in the ram reciprocating motion course of work
Driving force direction institute bending moment variation, improve the driving rigidity of machine ram, greatly improve machining accuracy.
To achieve the goals above, a kind of machine ram balancing device provided by the invention, including ram, the balancing device
It further include fixed beam, two fixed beams are symmetrically fixed with connecting plate on opposite two sidewalls, and ram is slidably connected on connecting plate,
Motor is installed at the top of ram, motor output end is rotatably connected to screw rod, and screw rodb base, screw rodb base are further fixed between connecting plate
On be fixed with nut, screw rod is protruded into nut and is spirally connected with nut, and nitrogen balance cylinder is equipped on screw rodb base, is pacified in fixed beam
Equipped with fixed frame, the nitrogen gas tank being connected to nitrogen balance cylinder is fixed in fixed frame；
The nitrogen balance cylinder includes cylinder body, the piston rod moved back and forth in cylinder body, the free end of the piston rod with
Ram is fixedly connected.
When using balancing device of the invention, can be fixed on lathe by fixed beam, motor rotary screw rod, screw rod from
It loosens in nut, so that ram moves up and down relative to fixed beam, since piston rod is fixedly connected with ram, when ram is to downslide
When dynamic, piston rod slide downward is driven, so that the nitrogen of nitrogen balance cylinder is upwards to offset the weight of ram.
This balancing device of the invention, it is ipsilateral since nitrogen balance cylinder is placed on motor, screw rod, so that motor
Straightness variation is smaller between nitrogen balance cylinder, and ram is able to respond quick up and down motion, improves machining accuracy.
Further, it is fixed with rectilinear orbit on ram side wall, sliding block is fixed on connecting plate, ram passes through rectilinear orbit
It is slidably connected on sliding block.Ram is set as sliding in fixed beam, further helps balancing in power, surely for single unit system
It is fixed.On the other hand, also it is conducive to bear the moment of flexure that gravity of ram and nitrogen balance cylinder gravity generate, effectively improves the drive of machine ram
Dynamic stiffness greatly improves machining accuracy.
Further, the output end of the motor is connected with shaft coupling, and shaft coupling is rotatably connected to screw rod.The shaft coupling added
Device helps the more stable rotary screw rod of motor.
Further, balance cylinder is mounted on inside screw rodb base, and piston rod stretches out screw rodb base and is fixedly connected with ram.In order to
Balance cylinder, can be mounted on inside screw rodb base by the weight of more balanced receiving balance cylinder.
Further, motor fixing plate is installed at the top of the ram, is fixed in the center position of motor fixing plate
Motor.In order to effectively prevent motor to influence the balance of single unit system in rotation, the motor fixing plate added is for making motor
Steadily.
Further, the fixed beam bottom is also connected with pedestal.In order to make whole device preferably average force, solid
Determine beam bottom portion and be further fixed on pedestal, facilitate the balance of whole device, and also contributes to the connection of balancing device and lathe.
By adopting the above technical scheme, the device have the advantages that including, by balance cylinder be fixed on driving motor,
At screw rod same lateral position, when ram moves downward, piston rod is driven to move downward, to offset the weight of ram；While this
Balance cylinder is arranged in sample, but also being straight square between balancing cylinder and driving motor, straightness changes during ram drop
It is small, to effectively improve machining accuracy.
