Device, including hydraulic cylinder 1, the second oil-through-hole 2, hydraulic cylinder 3, First piston bar 4, the first oil-through-hole 5, servomotor 6, servo
Push rod case 7, leading screw 8, servo push-rod 9, piston bridge 10, cylinder group lid 11, the 3rd oil-through-hole 12, second piston bar 13, sealing ring
14th, rail lock body 15, spring pad 16, roller 17, wheel shaft 18.
Wherein rail lock body 15 is located on rail 19, and it is moved on rail 19, and three are provided with rail lock body 15
Piston hole, second piston bar 13 is installed in each piston hole.The top of second piston bar 13 is provided with sealing ring 14.The rail lock
The top of body 15 is installed with cylinder group lid 11；The inner chamber for closing envelope is formed between steel group lid 11 and second piston bar 13.The steel group
The 3rd oil-through-hole 12 communicated with the inner chamber is offered on lid 11.When oil-filled to inner chamber by the 3rd oil-through-hole 12, second lives
Stopper rod 13 is pressurized and is pressed on the surface of rail 19 downwards.
The cylinder group lid 11 is affixed with piston bridge 10, and on piston bridge 10, first lives the outer sheath of First piston bar 4
The inner side of stopper rod 4 is encased in hydraulic cylinder 1, and hydraulic cylinder 1 is fixedly connected with mold-change trolley or other devices for needing adjustment position.
Hydraulic cylinder 3 is installed on hydraulic cylinder 1；The first oil-through-hole 5 is provided with the cylinder body of hydraulic cylinder 1；The hydraulic cylinder
The second oil-through-hole 2 is provided with lid 3.The hydraulic cylinder 1 and servo push-rod case 7 are affixed, and the outside of servo push-rod case 7, which is provided with, to be watched
Motor 6 is taken, the output shaft of the servomotor 6 is connected with leading screw 8 by shaft coupling.The leading screw 8 extend into servo push-rod case 7
The interior servo push-rod 9 with servo push-rod case 7 is set with, and the outer end of servo push-rod 9 is directed at the rail lock body 15 and piston rod
Frame 10.When servomotor 6 rotates forward, leading screw 8 releases servo push-rod 9, and when servomotor 6 inverts, leading screw 8 is by servo push-rod 9
Retract.
The running of the present invention：Dolly reaches one and closes on the original state that final position parking is fine setting, such as Fig. 1 institutes
Show.Distance according to required for actual condition, start servomotor 6 and drive leading screw 8 to rotate, the rotary motion conversion after cooperation
Into the axial movement of servo push-rod 9, servo push-rod 9 promotes rail lock body 15 and piston bridge 10, while also drives first to live
Stopper rod 4 moves right distance A simultaneously, as shown in Figure 2.Wherein " distance A " is a distance of description definition for convenience, and it can
To be any length in First piston bar scope of activities, and a certain length refered in particular to can not be regarded as.
Hydraulic oil is squeezed into from the 3rd oil-through-hole 12 on cylinder group lid 11 and continues pressurize, fluid shape in second piston bar 13
Into pressure second piston bar 13 is pushed down on, the lower end of second piston bar 13 stretch out, contacted with rail 19 and be against rail 19
On, sufficiently large stiction can be formed between rail the position of rail lock body 15 is locked on rail 19, reference picture 3.
As shown in figure 4, servo push-rod 9 is withdrawn into original position by reverse starting servomotor 6.
Hydraulic oil is passed through from the second oil-through-hole 2 of hydraulic cylinder 3 to want to force First piston bar 4 to be retracted, yet with steel
The position of rail lock body 15 has been locked, with its affixed integral piston bridge 10 block First piston bar 4 make its can not reverse displacement,
The hydraulic oil constantly squeezed into produces pressure and promotes hydraulic cylinder 1 to move right, and the final mold-change trolley that interlocks reaches accurate frock position
Put, as shown in Figure 5.
The bottom of rail lock body 15 can be provided with roller bearing 18 and roller 17, and roller 17 directly contacts rail 19, up in rail
Enter, make the movement of rail lock body 15 more smooth.
In the present invention, hydraulic cylinder 1 in an initial condition, the equal no pressure of fluid of rod chamber and rodless cavity, to ensure first
Piston rod can arbitrarily stretch out.
In the present invention, spring pad 16 is provided between the piston head and piston hole of second piston bar 13.Rail lock body 15 moves right
During dynamic distance A, spring pad 16 withstands second piston bar 13 and avoids it from producing frictional influence rail lock body between rail 19
15 movement.
In the present invention, between three piston holes perforate communicate, make the inner chamber between three second piston bars 13 and steel group lid 11
Be connected to it is logical, so as to which pressure can be produced to three second piston bars 13 from the hydraulic oil that the 3rd oil-through-hole 12 is squeezed into.
In the present invention, the hydraulic pressure weight of oil of elastic force ＞ second piston bars own wt+interior intracavitary of the spring pad, to protect
Card is not contacted between second piston bar and rail during advanced, not rubbed, and only can just make the after hydraulic oil pressurization
Two piston-rod lower ends stretch out.
The present invention by injecting hydraulic oil into the first oil-through-hole 5, the second oil-through-hole 2, the 3rd oil-through-hole 12 to control respectively
The misalignment of each several part processed, injection rate control well, and the displacement of part is visual, good control easily adjustment.
Beneficial effects of the present invention：1) present invention efficiently solves the problem of hydropress mold changing car positioning precision, pole
The earth shortens installation period.2) micromatic setting of the invention is whole uses liquid electric control, simple to operate, to operating personnel's technical ability
It is it is required that relatively low.3) micromatic setting in the present invention can be applied in all heavy duties need vernier device.
