Wherein the rail lock body 15 is arranged on the rail 19, and moves on the rail 19, three piston holes are arranged in the rail lock body 15, and a second piston rod 13 is arranged in each piston hole. A sealing ring 14 is arranged at the top of the second piston rod 13. The top of the steel rail lock body 15 is fixedly provided with a cylinder group cover 11; a closed inner cavity is formed between the steel set cover 11 and the second piston rod 13. The steel group cover 11 is provided with a third oil through hole 12 communicated with the inner cavity. When the oil is filled into the inner cavity through the third oil through hole 12, the second piston rod 13 is pressed downwards to be pressed against the surface of the steel rail 19.
The cylinder group cover 11 is fixedly connected with the piston rod frame 10, the outer side of the first piston rod 4 is sleeved on the piston rod frame 10, the inner side of the first piston rod 4 is arranged in the hydraulic cylinder 1, and the hydraulic cylinder 1 is fixedly connected with a die changing trolley or other devices needing position adjustment.
The hydraulic cylinder 1 is provided with a hydraulic cylinder cover 3; a first oil through hole 5 is formed in the cylinder body of the hydraulic cylinder 1; the hydraulic cylinder cover 3 is provided with a second oil through hole 2. The hydraulic cylinder 1 is fixedly connected with the servo push rod box 7, a servo motor 6 is arranged on the outer side of the servo push rod box 7, and an output shaft of the servo motor 6 is connected with a screw rod 8 through a coupler. The screw rod 8 extends into the servo push rod box 7 and is sleeved with the servo push rod 9 in the servo push rod box 7, and the outer end of the servo push rod 9 is aligned with the steel rail lock body 15 and the piston rod frame 10. The screw rod 8 pushes out the servo push rod 9 when the servo motor 6 rotates forward, and the screw rod 8 pulls back the servo push rod 9 when the servo motor 6 rotates backward.
The operation process of the invention comprises the following steps: the car reaching a near end position is the initial condition for fine tuning, as shown in fig. 1. According to the distance required by the actual working condition, the servo motor 6 is started to drive the screw rod 8 to rotate, the rotary motion is converted into the axial movement of the servo push rod 9 after being matched, the servo push rod 9 pushes the steel rail lock body 15 and the piston rod frame 10, and meanwhile, the first piston rod 4 is driven to move rightward by a distance A at the same time, as shown in fig. 2. The "distance a" is a distance defined for convenience of description, and may be any length within the movable range of the first piston rod, and cannot be regarded as a specific length.
High-pressure oil is pumped into the cylinder group cover 11 from the third oil through holes 12 and kept pressure is maintained, the pressure formed by the oil on the second piston rod 13 pushes the second piston rod 13 downwards, the lower end of the second piston rod 13 stretches out and contacts with the steel rail 19 and abuts against the steel rail 19, and enough static friction force can be formed between the second piston rod 13 and the steel rail to lock the position of the steel rail lock body 15 on the steel rail 19, and referring to fig. 3.
As shown in fig. 4, the reverse start servo motor 6 pulls the servo push rod 9 back to the original position.
The high-pressure oil is introduced from the second oil through hole 2 of the hydraulic cylinder cover 3 to force the first piston rod 4 to retract, however, as the position of the steel rail lock body 15 is locked, the piston rod frame 10 fixedly connected with the steel rail lock body clamps the first piston rod 4 to prevent the first piston rod from reversely displacing, the continuously-driven high-pressure oil generates pressure to drive the hydraulic cylinder 1 to move rightwards, and finally the die changing trolley is linked to reach an accurate tool position, as shown in fig. 5.
The bottom of the rail lock body 15 can be provided with a roller 18 and a roller 17, and the roller 17 directly contacts the rail 19 and runs on the rail, so that the rail lock body 15 can move more smoothly.
In the invention, the hydraulic cylinder 1 has no pressure in the oil liquid with a rod cavity and a rodless cavity in the initial state, so as to ensure that the first piston rod can be extended at will.
In the present invention, a spring pad 16 is provided between the piston head of the second piston rod 13 and the piston bore. During the rightward movement distance A of the rail lock body 15, the spring pad 16 props against the second piston rod 13 to avoid friction between the second piston rod and the rail 19 to influence the movement of the rail lock body 15.
In the invention, the openings among the three piston holes are communicated, so that the inner cavities among the three second piston rods 13 and the steel group cover 11 are communicated, and the high-pressure oil which is driven in from the third oil through holes 12 can generate pressure on the three second piston rods 13.
In the invention, the elastic force of the spring pad is larger than the self weight of the second piston rod and the weight of hydraulic oil in the inner cavity, so that the second piston rod is ensured not to be contacted with the steel rail in the advanced process, friction is not generated, and the lower end of the second piston rod can be extended only after the hydraulic oil is pressurized.
The displacement condition of each part is controlled by injecting hydraulic oil into the first oil through hole 5, the second oil through hole 2 and the third oil through hole 12 respectively, the injection quantity is well controlled, the displacement of the parts is visible, and the control is easy to adjust.
The invention has the beneficial effects that: 1) The invention effectively solves the problem of positioning precision of the hydraulic press die changing trolley, and greatly shortens the installation period. 2) The fine adjustment device disclosed by the invention adopts the hydraulic control in the whole process, is simple to operate and has lower requirements on the skills of operators. 3) The fine adjustment device can be applied to all equipment with heavy load needing fine adjustment.
