Abstract
The invention discloses a follow-up precise straightening hydraulic machine servo system operating mechanism which is provided with a multi-link mechanism driven by a ball screw; the multi-link mechanism controls the valve plug of a servo valve to move forth and back; and a cylinder controlled by the servo valve drives a pressure head to move downwards to straighten workpieces. The operating mechanism of the invention has simple operation, stable and reliable transmission and high feedback precision, and effectively controls the repeated position for the straightening pressure head to move downwards within 0.05 mm.
Description
Technical field:
The present invention relates to a kind of with the accurate alignment hydraulic press of ejector half servos manipulate mechanism.
Background technology:
The operating mechanism of servo-drive system, in conjunction with accompanying drawing, operating mechanism promptly is that servo valve 10 is controlled; When swinging block 11 bottoms, the valve core of servo valve reach is by oil cylinder (meaning not shown in the figures) the epicoele oil-feed of servo valve control; Driven plunger and pressure head 15 move downward, and the alignment workpiece promotes to move behind the valve core of servo valve when putting on the swinging block 11; The oil-feed of oil cylinder cavity of resorption, driven plunger and pressure head 15 backhauls.Existing operating mechanism is to control upward the putting of swinging block and the bottom through chain, and its drawback is: take off chain easily, transmission is unstable.
Summary of the invention:
For overcoming the defective of prior art, the object of the present invention is to provide a kind ofly with the accurate alignment hydraulic press of ejector half servos manipulate mechanism, realize straight-line Position Control through the reaction type mechanical linkage.This mechanism is simple to operate, and stable drive is reliable, and feedback accuracy is higher, has controlled repeatable position that alignment pressure head moves down effectively in 0.05mm.
Technical solution problem of the present invention adopts following technical scheme:
With the accurate alignment hydraulic press of ejector half servos manipulate mechanism; Rotating shaft that the nut of setting and ball-screw connects firmly and first pivoted arm that connects firmly with said rotating shaft; And be provided with the rotational travel of the screw mandrel of said ball-screw is carried out spacing baffle plate; It is characterized in that hinged successively lower link bar, second pivoted arm and long draw in the end of said first pivoted arm, the top of said long draw hangs with extension spring;
Said long draw is provided with the waist hole, in said waist hole, is connected with swing arm with bearing pin, and said swing arm is cross with long draw and is connected; It is hinged that one end and of swing arm is held piece tightly, saidly holds piece tightly and a guide post connects firmly, and said guide post connects firmly and workpiece carried out on the pressure head of alignment, and guide post is located on the frame that supports pressure head through guide rail;
The other end in said swing arm is provided with servo valve, on said servo valve, is hinged with a swinging block, and an end of said swinging block contacts with said valve core of servo valve, and the other end of swinging block contacts with the end of said swing arm.
Compared with present technology, beneficial effect of the present invention is embodied in:
1. simple to operate, convenient, stable drive is reliable; 2. the screw mandrel through the swing roller leading screw can be adjusted the rotational travel of school screw mandrel, and then can trace regulates the descending displacement of pressure head; 3. the descending displacement repeatable accuracy of alignment pressure head is higher; 4. simple in structure, easy for installation.
Description of drawings:
Fig. 1 is a structural representation of the present invention.
Label among the figure: 1 handle, 2 ball-screws, 21 nuts, 22 screw mandrels, 3 fixing chutes, 4 baffle plates, 5 first pivoted arms; 6 lower link bars, 7 second pivoted arms, 8 long draws, 9 swing arms, 10 servo valves, 11 swinging blocks; 12 extension springs, 13 guide posts, 14 hold piece tightly, 15 pressure heads, 16 rotating shafts, 17 frames.
Below pass through the specific embodiment, and combine accompanying drawing that the present invention is described further.
The specific embodiment:
Embodiment: combine Fig. 1; Present embodiment with the accurate alignment hydraulic press of ejector half servos manipulate mechanism, the rotating shaft 16 that the nut 21 with ball-screw connects firmly is set, rotating shaft can be rotated on frame; The rotating shaft 16 and first pivoted arm 5 connect firmly; The hinged long draw 8 in end of end hinged second pivoted arm 7, the second pivoted arms 7 of hinged lower link bar 6, lower link bar 6 in the end of first pivoted arm 5, the top of long draw 8 is with extension spring 12 suspensions; Rotational travel for the screw mandrel 22 of controlling ball-screw 2 is provided with arcuate fixed chute 3 in the rotating shaft periphery, and on chute 3, baffle plate 4 is set.
Long draw 8 is provided with the waist hole, in the waist hole, is connected with swing arm 9 with bearing pin, and swing arm 9 is cross with long draw 8 and is connected; It is hinged that one end and of swing arm is held piece 14 tightly, saidly holds piece tightly and a guide post 13 connects firmly, and guide post 13 connects firmly workpiece is being carried out on the pressure head 15 of alignment, and guide post 13 is located on the frame 17 that supports pressure head through guide rail;
The other end in said swing arm 9 is provided with servo valve 10, on servo valve 10, is hinged with a swinging block 11, and an end of swinging block contacts with said valve core of servo valve, and the other end of swinging block contacts with the end of said swing arm.
In the work, be fixedly connected with operating grip 1 on the screw mandrel 22, push handle 1 downwards; The nut 21 of ball-screw 2 drives rotating shafts 16 and rotates, and and then drive first pivoted arm 5 and rotate, long draw 8 is descending until driving; It is descending that long draw drives swing arm 9, and swinging block 11 is to lower swing, and the spool of servo valve 10 moves forward; By oil cylinder (meaning not shown in the figures) the epicoele oil-feed of servo valve control, driven plunger and pressure head 15 move downward, the alignment workpiece; Release handle 1, long draw 8 are up and to drive swing arm 9 up under the effect of extension spring 12, compress that pendulum promotes to move behind the valve core of servo valve on the swinging block 11, the oil-feed of oil cylinder cavity of resorption, and an alignment process is accomplished in driven plunger and pressure head 15 backhauls.
