Description
Technical field
The utility model discloses a kind of servo synchronous driving system of hyperbolic Shaft and NC Machining Test forging press.
Background technology
Hyperbolic Shaft and NC Machining Test forging press be a kind of to motor case, the isometric and wide panel beating thing of auto parts cut out, the high-accuracy mechanical equipment of punching, its structure mainly is made up of lathe base, support, two secondary AC servomotors, two secondary crankshaft linkages and slide block, every secondary crankshaft linkage comprises band transmission speed reducer structure, gear reduction, bent axle, ball head connecting rod and safety cylinder, and safety cylinder is connected with slide block.At present, the servo synchronous driving system of control hyperbolic Shaft and NC Machining Test forging press comprises controller, two servo amplifiers, two AC servomotors that have encoder, encoder is connected with controller again, this servo driven in synchronism form generally adopts the encoder of AC servomotor to be used as the slide block drive displacement feedback of hyperbolic axle Synchronization Control, the position probing mode of this slide block can not well be reacted the position of slide block reality, because also will be from the servomotor to the slide block through band transmission speed reducer structure, gear reduction, bent axle, mechanical part such as ball head connecting rod and safety cylinder, the mechanical clearance of these mechanical parts and the disturbance of actual loading all can cause two AC servos to drive the performance difference in loop, make two slide blocks can not realize that high precision synchronous drives.
The utility model content
For addressing the above problem, the utility model purpose is to provide a kind of servo synchronous driving system that can realize the hyperbolic Shaft and NC Machining Test forging press that two slide block high-precise synchronization drive.
The technical scheme that its technical problem that will solve the utility model adopts is: a kind of servo synchronous driving system of hyperbolic Shaft and NC Machining Test forging press, comprise controller, two grating checkout gears, two servo amplifiers that are connected with controller, two servo amplifiers are connected with an AC servomotor respectively, two AC servomotors are connected with an encoder respectively, two encoders are connected with controller again, and two grating checkout gears all are connected with controller, slide block respectively.
After the utility model adopts said structure, measure 2 displacements of slide block by the grating checkout gear, and feed back to controller, give AC servomotor by the defeated signal of controller, drive crankshaft connecting rod system and slide block work by AC servomotor, this AC servo Synchronization Control of carrying out the hyperbolic axle by 2 Displacement Feedback of slide block, walked around the influence of crankshaft connecting rod system to the final synchronous driving performance of slippage, directly carry out Synchronization Control according to the both sides displacement detecting of slide block, thereby better compensated the performance difference in two AC servo driving loops, realized that the slide block high-precise synchronization drives.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the utility model driven in synchronism schematic diagram.
The specific embodiment
As shown in Figure 1, a kind of servo synchronous driving system of hyperbolic Shaft and NC Machining Test forging press, comprise controller 1, two grating checkout gears 8,9, two servo amplifiers 2 that are connected with controller 1,3, two servo amplifiers 2,3 are connected with an AC servomotor 6 respectively, 7, two AC servomotors 6,7 are connected with an encoder 4 respectively, 5, crankshaft connecting rod system 11,12, two encoders 4,5 are connected with controller 1 again, two grating checkout gears 8,9 respectively all with controller 1, slide block 10 connects two crankshaft connecting rod systems 11,12 are connected with slide block 10.
The utility model is by grating checkout gear 8,9 measure 2 displacements of slide block 10, and feed back to controller 1, via controller 1 analyzing and processing, again signal is flowed to two AC servomotors 6 respectively, 7, AC servomotor 6, drive crankshaft connecting rod system 11 after 7 received signals again, 12, by driving crankshaft connecting rod system 11,12 drive slide block 10 work, this AC servo Synchronization Control of carrying out the hyperbolic axle by 2 Displacement Feedback of slide block 10, two crankshaft connecting rod systems 11 have been walked around, the influence of 12 pairs of final synchronous driving performances of slippage, directly carry out Synchronization Control according to the both sides displacement detecting of slide block 10, thereby better compensated the performance difference in two AC servo driving loops, realized that slide block 10 high-precise synchronization drive.
