Description

Technical Field

[0001] The utility model relates to the technical field of hot die forging presses, in particular to a built-in screw rod large-stroke slider adjustment structure. Background Art

[0002] The slider of the single-point press is adjusted, but the screw is external. The screw has a small outer diameter and poor rigidity. It is easy to deform and bend, resulting in adjustment obstruction or even jamming, which has a serious impact on production. After the screw is external, with vibration, the lubricating oil flows seriously, which is easy to be contaminated with dust and affects the service life of the thread. The traditional motor drives the screw, which has low torque and cannot be digitally controlled. The traditional slider adjustment mechanism can no longer meet the requirements of the rapid development of mechanical parts manufacturing. Utility Model Content

[0003] In view of the problems existing in the prior art, the utility model discloses a built-in screw rod large stroke slider adjustment structure, the technical scheme adopted is, comprising a slider body and a connecting rod, a cover plate is fixedly installed at the opening of the side of the slider body, a plurality of T-shaped slots are opened at the bottom of the slider body, a motor is fixedly installed in the groove at the top of the slider body, the output shaft of the motor passes through the through hole at the bottom of the groove on the slider body and is fixedly connected to one end of a first worm, the other end of the first worm is rotatably connected to the bottom of the slider body, a first worm wheel is rotatably installed on the inner side surface of the slider body, the first worm wheel is meshed with the first worm, the middle part of the end surface of the first worm wheel is fixedly connected to one end of a second worm, two fixing rings are fixedly installed on the inner side surface of the slider body, the side surfaces of the two fixing rings are respectively fixedly connected to the outer rings of the two bearings, the inner rings of the two bearings are respectively fixedly connected to the top and bottom of the second worm wheel, the second worm wheel is meshed with the second worm, the thread of the inner side surface of the second worm wheel is threadedly connected to the screw rod, and the upper end of the screw rod is fixedly connected to the lower end of the connecting rod.

[0004] As a preferred technical solution of the present utility model, the motor is a servo motor.

[0005] The beneficial effects of the utility model are as follows: the utility model drives the first worm to rotate through a motor, so that the first worm drives the first worm wheel to rotate, so that the first worm wheel drives the second worm to rotate, so that the second worm drives the second worm wheel to rotate, and the thread on the second worm wheel drives the lead screw to move up and down, thereby completing the large stroke adjustment of the slider. Through the drive of a servo motor, digital control can be realized, which is more stable. The two-stage drive of the double worm and double turbine transmits greater force than the traditional ball-head lead screw and is more durable. The enlarged outer diameter built-in lead screw is more impact-resistant than the external ball-head lead screw (the diameter of the enlarged outer diameter built-in lead screw is 40-50% larger than the diameter of the external ball-head lead screw), and the impact resistance coefficient is doubled, and deformation and bending will not occur. The durability and stability are stronger. The built-in lead screw has good airtightness and is always immersed in lubricating oil, so it will not be contaminated by dust and has very little wear.
