Embodiment Construction

[0037] The following is a further modeling analysis of the scissor jack.

[0038] 1. Modeling analysis of scissor jack

[0039] According to the actual movement of the scissor jack, one section of the screw kinematic pair is an articulated pair, and the other section is a moving pair. When the motor drives the screw to rotate, the connecting nut moves horizontally relative to the horizontal rod and drives the lifting arm up and down (when the screw rotates clockwise, the connecting nut moves toward the hinged end relative to the screw, and the lifting arm rises; when the screw rotates counterclockwise, the connecting The nut moves away from the hinged end relative to the screw rod, and the lifting arm descends). From this, a motion model diagram is established, such as figure 2 , taking D as the coordinate origin (0, 0), setting the angle between the screw rod and the lifting arm as α (0°<α<90°), and the arm length as L, then the hinge point A, vertex B and point C of the m...

Abstract

The invention discloses a level adjusting device and a method thereof. The level adjusting device includes a support plane, an execution mechanism and a control unit. The execution mechanism and the control unit are located below the support plane respectively. The execution mechanism includes a fixing support foot and two shear-type jacking driving devices. The level adjusting device adopts a PD closed-loop control algorithm to use a parameter obtained by an inclination-angle sensor as a feedback of driving of the execution mechanism by an embedded-type controller so that the level can be adjusted rapidly and accurately and the shear-type jacks are used as the execution mechanism and through reduction gearboxes, stepping motors drive lead screws of the shear-type jacks to rotate so as to adjust the ascending and descending of the support foot. The level adjusting device and the method thereof have the characteristics of being high in adjustment speed, high in adjustment precision and great in bearing performance; and the level adjusting device is simple and compact in structure, high in stability and wide in practicality.

Description

technical field [0001] The invention relates to a level adjustment device, in particular to a level adjustment device that automatically detects the inclination angle of a plane and adjusts the level. It is suitable for situations where there is a high requirement for the placement angle of instruments, and belongs to the application of computer embedded technology in machines or equipment. application in the base. Background technique [0002] At present, the known level adjustment mainly relies on adjusting the level bolt, and the adjustment of the balance is realized by manually moving the wrench to adjust the bolt up and down. The level is measured visually by the human eye, and the manual adjustment of the bolt has a great influence on the result of the level adjustment. At present, the existing automatic leveling device is composed of an inclination sensor, a controller, a motor driver and a stepping motor. The device adjusts the relative heights of the three supporti...
