Description
Technical field
The present invention relates to a kind of feeding compensation devices more particularly to a kind of bearing inner race channel grinding machine tool auto-feed to compensate
Device.
Background technique
In the processing of bearing inner race ditch grinding machine tool, it is often necessary to which the trim amount of processing capacity and grinding wheel to workpiece carries out
Synchroballistic is to be realized by grinding frame and trimmer progress auto-feed compensation to ditch grinding machine tool.
Traditional feed compensation movement is that thermal compensation signal is sent by PLC to solenoid valve, and electromagnetism valve events put down hydraulic oil
Two-way is divided to send to the hydraulic oil cylinder with gear racks of mill frame and trimmer feeding position, oil cylinder with gear racks is matched by moving upwards drive
Gear rotation, gear and ratchet hook one, ratchet hook rotation stress drive ratchet rotation, and ratchet is connected with worm screw, snail
Bar rotation drives turbine rotation, and turbine is connected with feed screw by simultaneously cap locking, completes primary feed；Solenoid valve loses when reset
Electricity, spring withstand oil cylinder with gear racks and move downward band moving gear opposite direction rotation, and it is in situ that ratchet links up with de- power return.
Due to using hydraulic oil driving hydraulic cylinder to promote, the stability shadow of the size and stability of hydraulic pressure to feeding
Sound is larger, and the oil cylinder with gear racks at two feeding positions is the hydraulic oil for sharing the supply of a solenoid valve, is easy to appear parts depreciation
Etc. reasons cause the inconsistent of feed compensation amount, for example, wherein the new oil sealing of the cylinder replacing on one side causes the resistance of motion to increase,
It will lead to unilateral oil cylinder with gear racks and movement travel be not achieved.Due to the amount of feeding number depend on oil cylinder with gear racks and move upwards
Stroke size, so the limited screw for needing dozen table to adjust oil cylinder with gear racks repeatedly after replacement feeds some accessory of position controls
The stroke of cylinder movement, it is necessary to assure the amount of feeding that mill frame and trimmer are completed is identical, if amount of feeding adjustment is asynchronous,
The size that machine tooling comes out will do over again or scrap always, and stability is poor.
When midway being needed to modify grinding wheel or the plus-minus amount of feeding in equipment running process, worker is needed to put in hand inside lathe
The handwheel for going rotation to be connected with worm screw completes feeding, and doing when hand feed movement in worker is that will not close the grinding wheel of lathe
It closes, this, which just has bigger security risk, exists.
When equipment needs replacing new grinding wheel, worker has to locking turbine and screw rod and cap and strikes pine, then with pulling
Hand reversely rotates screw rod, and the workbench for grinding frame and trimmer is withdrawn, and not only cumbersome laborious, manually retracted stroke is also
Have has few, waste of manpower more.
Summary of the invention
It is an object of the invention to: in view of the drawbacks of the prior art, propose that a kind of bearing inner race channel grinding machine tool is automatically same
Stepping compensation device is not only simple in structure, is easy to maintenance, safety easy to operate, and control feeding that can be effectively stable
The size of compensation rate.
The technical scheme adopted by the invention is that:
A kind of bearing inner race channel grinding machine tool auto-feed compensation device, comprising: PLC, the pulse generation being connect with the PLC
Device, the controllor for step-by-step motor being connect with the impulse generator, the stepper motor being connect with the controllor for step-by-step motor, with
The worm screw of the output axis connection of the stepper motor, the turbine being meshed with the worm screw and the silk with the turbine tight fit
Bar；
Wherein, the screw rod is connected with workbench；
The stepper motor drives the worm screw rotation, and then drives the turbine rotation, and the turbine rotation drives the silk
Bar rotation, the screw rod rotation drive the workbench to move in a straight line.
Further, the turbine and the screw rod are locked by locking nut, are realized and are fitted close.
Further, the output shaft of the stepper motor is connect with the worm screw by shaft coupling.
Further, the impulse generator is also connected with the plus-minus button for adjusting the table feed amount, should
Plus-minus button is arranged on the operation panel of the workbench.
Further, the end of the worm screw connects handwheel.
When carrying out straight-line feed compensation work, feed compensation signal is sent to impulse generator, impulse generator by PLC
The operating that controllor for step-by-step motor controls stepper motor according to the size of the compensation rate of setting is controlled, then passes through the defeated of stepper motor
Shaft outputs power to worm screw, and the rotation by controlling worm screw drives turbine rotation, and turbine rotation drives screw rod rotation, screw rod
Rotation drives workbench to move in a straight line；
Due to being that worm screw drives turbine, thus more can accurately transmit compensation rate, the linear motion of workbench drives mill thereon
Frame and trimmer make axial feed.
The beneficial effects of the present invention are:
The present invention compares traditional compensation device, enormously simplifies the structure of autocompensation installation, and vulnerable part is reduced, repair and replacement
It is convenient；
Using step motor control turbine and worm combination by the way of come feed compensation amount, keep feed compensation highly stable, mill frame and
The compensation consistency of trimmer is effectively ensured, and adjustment feed compensation amount is very convenient, reaches machine with hand without worker
Handwheel is adjusted in bed, and only needs to raise the control parameter of whole stepper motor i.e. with safety is improved in operation panel；
When new grinding wheel position is arranged, also only feeding step number need to be returned into new grinding wheel position on operation panel, it is easy to operate, and row
Journey result is more accurate than being manually operated.
