Problems solved by technology

[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, it is often limited by the installation space and dimensions of the equipment.

Embodiment Construction

[0025] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0026] A composite motion mechanism, including a displacement output shaft 1, a limit pin 2, a mechanism housing 3, a screw rod 4, a screw rod 5, a bearing 6, a coupling 7, and a rotating drive element 8, wherein the displacement output shaft 1 Radial mounting holes 13 are processed on the outer circumference, and spiral grooves 12 are processed on the inner surface. The mechanism casing 3 is a hollow cylindrical structure. Connecting flanges are processed on the outer circumferences of the two ends of the cylinder respectively. The hollow part of the cylinder is divided into Small-diameter part and large-diameter part, two axisymmetric axial grooves 11 are processed on the inner surface of the small-diameter part, and limited grooves are processed on the large-diameter part. There is an annular boss on which two radially extending symmetrical lugs are processed, rai...

Abstract

The invention discloses a compound motion mechanism, which comprises a displacement output shaft, a limit pin, a mechanism housing, a screw rod, a screw rod, a bearing, a shaft coupling, and a rotating drive element, and the screw rod of the motion mechanism is a displacement output shaft Provide linear motion power, the screw rod provides rotational motion power for the displacement output shaft, and uses the form of the limit groove to control the generation of linear displacement, rotational displacement and combined displacement, and then determines the output form of the displacement output shaft. Using this invention can make linear motion and Rotary motion shares a set of mechanisms. By adjusting the structural parameters or control parameters, the combined action sequence of linear motion and rotary motion can be realized. The structure is simple, the volume, weight and power consumption are small, and it can be applied to special automatic production line equipment for mass production. , Automatic opening and closing of vehicle hatches, etc., has a good application prospect.

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...
