Embodiment Construction

[0010] A linkage mechanism based on a ball screw pair, including: a connecting rod 7, and also includes: a ball screw pair 1, a ball hinge fixing seat 2, a ball hinge upper support 3, a ball hinge lower support 4, and a ball hinge adjustment Spacer 5 and cylindrical pin 6. The ball screw pair 1 includes: a ball screw 8 , a ball nut 9 and a ball 10 . The outer cylindrical surface of the ball screw 8 and the inner cylindrical surface of the ball nut 9 are respectively processed with spiral raceways, and the balls 10 are installed in the spiral raceways formed by the ball nut 9 and the ball screw 8 . The ball screw 8 is processed with an abdominal cavity, and the wall of the abdominal cavity is processed with steps and threads. The ball hinge fixed seat 2 is threadedly connected with the ball screw 8, and the spherical hinge fixed seat 2 is limited by the cylindrical pin 6. The ball hinge upper support 3 is placed on the ball hinge fixed seat 2, and the ball hinge adjusting gas...

Abstract

The invention discloses a ball screw assembly based link mechanism comprising a ball screw assembly (1), a spherical hinge holder (2), a spherical hinge upper support (3), a spherical hinge lower support (4), a spherical hinge adjusting washer (5), a cylindrical pin (6), and a link (7). The ball screw assembly (1) comprises a ball screw, a ball nut and a ball. When the ball nut is driven to rotate by external power, the ball nut drives the ball screw to linearly move through the ball, the ball screw drives the link (7) to both linearly move and rotate so as to drive an external rocker to rock, and required power is finally output. The ball screw assembly (1) and the link (7) are combined to the link mechanism to output required motion, structural deviations are eliminated, and operating space is compressed.

Description

technical field [0001] The invention relates to a link mechanism, in particular to a link mechanism based on a ball screw pair. Background technique [0002] There are many types of linkage mechanisms, among which the slider rocker mechanism is used to solve the problem of motion conversion between movement and swing. The kinematic relationship of the slider rocker mechanism is that the force pushes the guide slider to move in a straight line, and the rocker is driven to swing through the connecting rod. In some specific working occasions, the connecting rod needs to be embedded in a relatively narrow space to compress the overall space of the device. Due to less space considerations, the traditional slider-rocker mechanism takes up a lot of space, and is not suitable for workplaces with narrow spaces, and the slider, connecting rod and remote rod are in the same plane, which not only requires high installation requirements, but also cannot eliminate structural deviations ...
