The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described further:
Like Fig. 1, shown in 2 and 3: a kind of piston ring side positioning numerical control grinding machine; Comprise workbench 11, abrasive grinding wheel 4, material-dropping hole 5, taper feed mechanism 6, binder servomotor 7, pressure head 8, ring to be processed 9, pusher servomotor 10, change-over switch 12, numerical control device 13 and blanking reason ring bar 14; Said workbench 11 tops are provided with taper feed mechanism 6; Be provided with ring 9 to be processed in the taper feed mechanism 6; Ring to be processed 9 upper ends are provided with pressure head 8; Pressure head 8 is connected with binder servomotor 7, and said taper feed mechanism 6 is connected with pusher servomotor 10, and binder servomotor 7 is connected with numerical control device 13 with pusher servomotor 10; Be provided with abrasive grinding wheel 4, platform plane part 2, platform lozenges part 1 and material-dropping hole 5 successively by taper feed mechanism 6 traffic directions on the said workbench 11; The below of material-dropping hole 5 is provided with blanking reason ring bar 14, and said platform plane part 2 is provided with change-over switch 12 with the intersection 3 of platform lozenges part 1, and this change-over switch 12 converts the position control mode change-over switch into for binder servomotor 7 torque control models.
The course of work of the utility model piston ring side positioning numerical control grinding machine is following:
After the last consignment of workpiece machined, taper feed mechanism 6 was in position shown in Figure 1, and promptly the intersection 3 of platform plane part 2 and platform lozenges part 1 is piled up ring 9 to be processed in the taper feed mechanism 6 by manual work then, and gap-clearance of piston rings this moment is alignd.
Numerical control starts the back:
The 1st step: binder servomotor 7 drives pressure head 8 binders, until receiving the pressure appropriate signals;
The 2nd step: pusher servomotor 10 is pushed taper feed mechanism 6 (joining the binder servomotor 7 with the top) to diamond grinding emery wheel 4 forward, and taper this moment feed mechanism 6 nethermost loops will process the location and use the R groove, accomplish the grinding of workpiece;
The 3rd step: pusher servomotor 10 drives taper feed mechanism 6 and retreats into material-dropping hole 5 positions;
The 4th step: start binder servomotor 7 a bottom loop is dropped on the blanking reason ring bar 14;
The 5th step: pusher servomotor 10 drives the intersection 3 that taper feed mechanism 6 arrives platform plane part 2 and platform lozenges part 1 again forward.
Repeated for 1～5 step, process next loop, ring is sent material level to signal by whole completion of processing in feed mechanism, and the counter-rotating of binder motor is reclaimed pressure head to highest point, waits for that material loading restarts numerical control.
In the 4th step, can fall smoothly in order to guarantee piston ring, the binder motor will press down a segment distance; This distance will be above the thickness of a loop; After a consequently bottom loop falls, below loop second from the bottom will give prominence to about half ring thickness of feed mechanism lower plane, go in order to get back to this loop holder in the feed mechanism; The technical scheme that the utility model proposes is: along with the promotion forward of pusher motor; Current bottom one loop will receive the picking-up of lozenges, progressively get back in the feed mechanism, but since above the pushing of binder motor is arranged; Might cause pressure too big, the control model of binder servomotor is set to the torque control model for this reason: a torque limit value T is set
L, as actual torque T
d＜T
L, motor is just changeing and is pressing down; Work as T
d＞T
L, the motor counter-rotating is reclaimed; Work as T
d=T
L, the motor stall is sent pressure simultaneously and is reached limited signal (being the pressure appropriate signals).Platform lozenges end and after, this pressure will be maintained, and utilizing lozenges will encircle in picking-up and the follow-up process, will remain a suitable pressure on the ring like this.For when the blanking; In the torque control model ring in the feed mechanism is not all pressed because of machine operation; Control model with motor when ring arrives platform lozenges end switches to position control mode; Blanking finishes the back returns and is cut to the torque control model, through the cooperating of frame for movement and electrical control, has solved the problem that exists in the manual processing like this.
Further need the problem of explanation to be, what need to keep is the pressure that is added on the ring, and the control of torque control mode is that motor has constant torque, and the torque of mandatory declaration binder motor and the pressure on the pressure head are dull corresponding relationship for this reason.Because what pressure head and binder motor adopted is the ball-screw syndeton, as shown in Figure 4, comprises feed screw 15 among the figure, ball nut 16, driving torque T
e17, axial compressive force F
a18, by related data [Wang Zhimin, Zhang Xizhong, strict brave. the ball-screw transmission is used and development [J]. electromechanical engineering technology, 2004, (9)] can know driving torque T among Fig. 4
eWith axial compressive force F
aRelation be:
In the formula: F
a---axial compressive force;
η---transmission efficiency, relevant with pitch with the screw mandrel nominal diameter;
T
e---the motor-driven torque;
P
h---pitch (helical pitch)
This formula shows, under the situation that pitch and screw mandrel nominal diameter are confirmed, and driving torque T
eWith axial compressive force F
aBetween be proportional relation, dull corresponding, therefore the control to pressure just is converted into the control to torque.
