Vertical movement platform with horizontal bearing capacity

Abstract

The invention discloses a vertical movement platform with the horizontal bearing capacity. The vertical movement platform comprises an actuator, a bearing frame, a steel wire rope, a leading-in pulley, a leading-out pulley, a motor, a motor support, a lead screw, a sliding block, a sliding plate, a spring, a bearing bolt, a leading-in hole, a guide bolt, a pulley seat, a support hole, a bearing bolt positioning hole, a sliding plate, a leading-out hole, a lead screw support, a sliding plate guide hole, a passive clearance, an active clearance, a pulley seat guide hole, a positioning guide holeand a guide bolt positioning hole. According to the vertical movement platform, automatic space positioning of the stretching position of the steel wire rope is achieved. Through fastening of the bearing bolt, the pulley seat and the bearing frame are fixedly connected, the borne large load is transmitted to the bearing frame through the pulleys and the pulley seat, and the horizontal force borneby the lead screw can be adjusted through the rigidity of the spring. According to the vertical movement platform, the space adjustment of the output position of loading force is achieved, the loading force totally acts on the bearing frame, and the lead screw is prevented from bearing large horizontal loads.

Description

technical field [0001] The invention relates to a vertical motion platform with lateral bearing capacity, in particular to a large-stroke motion platform with gap adjustment and transformation of the load-bearing structure, and belongs to the technical field of mechanical environmental tests. Background technique [0002] The electric motion platform has the obvious advantages of high precision, high speed and high acceleration, and is widely used in various industrial fields such as CNC machine tools and electronic packaging. The motion platform is generally composed of servo motor, ball screw, slider, servo drive, motion controller, host computer software and load. In addition to the motion requirements of large strokes, higher requirements are placed on the vertical load of the motion platform in the fields of hoisting and static tests. However, due to the poor lateral bearing capacity of the ball screw, the motion platform generally cannot bear large lateral loads. [...
