Description
【Technical field】
The utility model belongs to field of machining technology, more particularly to a kind of numerically-controlled machine tool tapping control system.
【Background technology】
Current rigid tapping root is roughly divided into following two according to main shaft type：One, main shaft is Analog control, referred to as
For frequency spindle, frequency converter carries out simplest opened loop control to spindle motor, through encoder that the operation of spindle motor is fast
Degree feeds back to CNC controller.Two, main shaft is impulse controller, referred to as servo principal axis, and servo-driver carries out motor certain
The control of closed loop principle, carry out real-time rotating speed correction through the subsequent encoder of motor, control accuracy is slightly higher.Both the above situation
The tapping mode used is to follow tapping, it is so-called follow tapping be exactly axis servomotor order amount by with the position feedback of main shaft and
Correct, it is therefore intended that tooth away from fixation.It follows and is primarily present following two problems in tapping actual use at present：1) tapping hole
Bottom low precision, because being to follow tapping, the bounce of speed of mainshaft any point can all cause the change in location of servo axial direction,
The stage that especially main shaft deceleration commutation accelerates in bottom hole often goes wrong；2) tapping efficiency is low, because being easy in bottom hole
Cause bottom hole precision not high, so can generally bottom hole be used to suspend technology, that is, after being axially moved to bottom hole, main shaft can dally
For a period of time, then main shaft just inverts and axial direction moves to starting point, protects bottom hole precision to a certain extent in this way,
But the time of tapping is sacrificed, it is apparent poor in efficiency.
Therefore, it is necessary to provide a kind of new numerically-controlled machine tool tapping control system to solve the above problems.
【Utility model content】
The main purpose of the utility model is to provide a kind of numerically-controlled machine tool tapping control system, tapping speed is fast and attacks
The bottom hole precision of tooth is high.
The utility model is achieved through the following technical solutions above-mentioned purpose：A kind of numerically-controlled machine tool tapping control system, packet
It includes supervisory controller, the main shaft amplifier that is connect with the supervisory controller and axial amplifier, amplify with the main shaft
The main shaft rotating servo of device connection and the axial feed servo being connect with the axial amplifier；The supervisory controller packet
Include decoder, the feed servo control module that is connect with the decoder and rotating servo control module；The PC control
The rate curve of control main shaft rotating servo action is provided in device, the rate curve includes rotating forward part and inversion section,
The rotating forward part and the inversion section are first to accelerate to slow down afterwards, acceleration portion in the rotating forward part and the inversion section
The absolute value with the acceleration of deceleration part is divided to be equal.
Compared with prior art, a kind of advantageous effect of numerically-controlled machine tool tapping control system of the utility model is：Control
Device is according to the tooth in tapping program away from while sending main shaft rotation and axial feed order so that main shaft rotating servo and axial direction
Hysteresis quality of the feed servo in terms of signal reception and execution obtains effective solution；And it feedovers in conjunction with supervisory controller
Compensation so that main shaft axially move to after bottom hole just can gapless axial counter motion to starting point, coordinate host computer control
The rate curve of main shaft rotating servo action is controlled in device processed, on the one hand the gapless docking of control main shaft forward and reverse makes
Tapping efficiency is obtained to greatly improve；On the other hand, the tapping precision of bottom hole is substantially increased；Uniform acceleration reversely accelerates abundant body
The high efficiency of tapping control system is showed, while having avoided main shaft and dallying the waste tapping time in bottom hole.
【Description of the drawings】
Fig. 1 is the control principle block schematic illustration of the utility model embodiment；
Fig. 2 is the utility model embodiment medium velocity curve synoptic diagram.
【Specific implementation mode】
Embodiment：
Fig. 1-Fig. 2 is please referred to, the present embodiment is numerically-controlled machine tool tapping control system comprising supervisory controller and institute
State the main shaft amplifier and axial direction amplifier, the main shaft rotating servo that is connect with the main shaft amplifier of supervisory controller connection
And the axial feed servo being connect with the axial amplifier；The supervisory controller includes decoder and the decoding
The feed servo control module and rotating servo control module of device connection；Control main shaft rotation is provided in the supervisory controller
The rate curve S, the rate curve S for turning servo action include rotating forward part I and inversion section II, I He of rotating forward part
The inversion section II is first to accelerate to slow down afterwards, accelerating part and deceleration in the rotating forward part I and the inversion section II
The absolute value of partial acceleration is equal.
The control method of the present embodiment numerically-controlled machine tool tapping control system includes the following steps：
1) it provides in a tapping program to the supervisory controller；
2) decoder is according to the tapping program, independently under the main shaft amplifier and the axial amplifier
Up to order；The decoder is interpreted, the order amount of internal calculation main shaft and axial direction according to the tapping program
3) the axial amplifier transfer signals move to starting point to the axial feed SERVO CONTROL；
4) supervisory controller detects whether the main shaft rotating servo is in stop motion state, if it is not, then
It alarms；If then carrying out next step；
5) the main shaft rotating servo is completed to rotate forward part I, while the axial feed servo according to the rate curve S
Bottom hole is moved to, since axial feed servo falls behind at this time in order to ensure the low precision in hole, the supervisory controller is to the axis
Feedforward compensation is done to feed servo so that the axial feed servo does not stop after tool motion is low to hole；
6) the main shaft rotating servo complete rotate forward part I it is flashy start simultaneously at it is complete according to the rate curve S
At inversion section II, while the axial feed axis servomotor runs back to starting point, completes tapping program.
Quick tapping continues in principle with dynamic tapping correlation specification, but the present embodiment is when bottom hole inverts, by bell plus-minus
Fast Activity design be etc. deceleration directly invert, therefore can effectively reduce vibratory output generation.
The advantageous effect of the control method of the present embodiment numerically-controlled machine tool tapping control system is：Controller is according to tapping journey
Tooth in sequence is away from while sending main shaft rotation and axial feed order so that main shaft rotating servo and axial feed servo are being believed
Number receive and execution in terms of hysteresis quality obtain effective solution；And supervisory controller is combined to carry out feedforward compensation so that main
Axis be axially moved to bottom hole after just can gapless axial counter motion to starting point, coordinate and control master in supervisory controller
The rate curve of axis rotating servo action, the gapless docking of control main shaft forward and reverse, on the one hand so that tapping efficiency is big
Big raising；On the other hand, the tapping precision of bottom hole is substantially increased；Uniform acceleration reversely accelerates to have fully demonstrated tapping control
The high efficiency of system；Meanwhile it avoiding main shaft and dallying the waste tapping time in bottom hole.
Above-described is only some embodiments of the utility model.For those of ordinary skill in the art,
Without departing from the concept of the present invention, various modifications and improvements can be made, these belong to this practicality
Novel protection domain.
