Combined-type movement mechanism

Abstract

The invention discloses a combined-type movement mechanism which comprises a displacement output shaft, a limiting pin, a mechanism shell, a screw rod, a lead screw, a bearing, a coupler and a rotating driving element. The lead screw of the movement mechanism provides linear movement power for the displacement output shaft. The screw rod provides rotating movement power for the displacement output shaft. Linear displacement, rotating displacement and combined displacement are controlled in the mode of a limiting groove, and then the output form of the displacement output shaft is determined. By using the combined-type movement mechanism, linear movement and rotating movement can share a set of mechanism. The combined motion sequence of the linear movement and the rotating movement can be achieved by adjusting structural parameters or control parameters, the structure is simple, the size is small, the weight and the power are low, and the combined-type movement mechanism can be applied to the aspects such as automatic production line devices special for mass production and automatic opening and closing of device vehicle cabin doors, and have good application prospects.

Description

technical field [0001] The invention relates to a mechanism capable of completing a combined action sequence of linear motion and rotary motion, which belongs to the technical field of mechanisms and machinery, and in particular relates to a composite motion mechanism. Background technique [0002] In the application of mechanical and automatic control engineering, some equipment needs to complete the combined action sequence of linear motion and rotary motion, which requires the use of linear motion drive mechanism and rotary motion drive mechanism to complete the action sequence alternately, but the mechanism structure of this mode is complicated. The size, weight, and power consumption are large, and in practical applications, they are often limited by the installation space and dimensions of the equipment. Contents of the invention [0003] In view of this, the present invention provides a compound motion mechanism, which uses a screw rod to provide linear motion power...
