Description
Technical field
This utility model relates to one and directly drives knife rest nonshared control unit, belongs to knife rest and controls technical field.
Background technology
At present, servo saddle i.e. drags servomotor with servo-driver and removes band movable knife rack, compared with conventional hydraulic knife rest,
It has, and rotating speed is high, position advantage accurate, low-cost.The concept of domestic servo saddle is the most just to put forward, so
Matured product on market is the most few.The producer abroad having several Drive technologies ripe is specifically designed for servo saddle exploitation
Product, such as Italy Baruffaldi, Japan Rhizoma Sparganii etc..The product of domestic-developed application is substantially with state
Outer generic servo driver is main body, adds a PLC (Programmable Logic Controller) or single-chip microcomputer, be outside driver
A kind of control structure containing host computer, PLC and driver, PLC is obtained by I/O mouth communication with host computer
Target cutter spacing number, PLC becomes cutter spacing number conversion to the command pulse number of driver to realize servo saddle driver again
Function.
Existing servo saddle mainly divides three kinds of mode of operations:
(1) back to zero pattern, when system first powers on, it is necessary to carry out back to zero pattern operation, to find on knife rest
One station.During back to zero pattern, the base of cutterhead is installed a proximity switch, the cutterhead rotated is installed one
Individual inductive head, cutterhead rotation turn around, inductive head through proximity switch once, whenever inductive head is through proximity switch, zero
Point signal circuit conducting, driver determines the position of the first station according to this signal.
(2) automatic mode, knife rest, according to the instruction of host computer, runs to different stations, in order to carry out work pieces process.From
During dynamic model formula, driver, by the I/O signal being connected with host computer, receives target cutter spacing, calculates target cutter spacing and works as
The difference of front cutter spacing, by the product of above-mentioned difference Yu the umber of pulse of every station, calculates the overall pulse number needing to run,
And be transformed into cycles per instruction operation, then by the instruction smoothing processing of software inhouse, it is possible to the arrival target of quick and stable
Station.
(3) manual mode, pins tool changing button in a manual mode, and knife rest rotates the most always, after release button, and knife rest
Run to nearest station stop.Before manual mode mainly processing, debugging is used.During manual mode, according under host computer
The enable signal sent out runs stopping, having enable signal then internal drive automatically to send the pulse of a station, has sent
Cheng Ze judges whether also to enable signal, has the pulse then continuing to send a station, until enabling signal cancellation.
Shortcoming existing for existing servo saddle is: (1) determines the first station due to needs according to the signal of inductive head
Need to regulate zero compensation parameter, and repeatedly to regulate to compensate and put in place；If inductive head occurs to loosen in using,
Then after fastening inductive head, need zeroing compensating parameter again.Therefore, existing servo saddle needs to install close to opening
Closing and inductive head, installation and debugging bother.(2) driver can not according to the change auto-adjustment control parameter of working condition,
Thus in the operation automatically of servo saddle, the parameter of driver keeps constant, when in knife rest, the flow of liquid is sent out with pressure
During raw a range of change, the bit time that runs to of cutterhead can be produced impact.
