specific Embodiment

[0022] Specific examples, see Figure 1-Figure 3 : The Cartesian coordinate system is the XY coordinate system, the movement direction of the first output end of the first linear servo cylinder 1 is the lateral movement of the X coordinate system, and the movement direction of the second output end of the second linear servo cylinder 2 is the longitudinal direction of the Y coordinate system The two linear servo cylinders are combined to form a plane of the XY coordinate system. The two ends of the length direction of the first piston rod 101 of the first linear servo cylinder 1 are respectively positioned at the corresponding positions of the casing 3 of the slewing mechanism. The first straight line The first cylinder body 102 of the servo cylinder 1 moves laterally in the X coordinate system along the length direction of the first piston rod 101. The first cylinder body 102 is fixed to the second linear servo cylinder 2 through the first connecting seat 6, and the second lin...

Abstract

The invention provides a vector rotation mechanism with servo cylinders. The mechanism is simple in structure, the output corner reaches 360 degrees, the mechanical efficiency is high, and reliabilityis high. The mechanism comprises two linear servo cylinders including the first linear servo cylinder and the second linear servo cylinder, the two linear servo cylinders are arranged in a 90-degreemanner on the space, a rotation mechanism shell is further included, an input rotating arm shaft, and an output rotating shaft are arranged on the rotation mechanism shell, the input rotation arm shaft is inserted in the radial positioning structure of the output rotating shaft, the output rotating shaft is inserted in a bearing inner ring of an output rotating shaft hole of the rotation mechanismshell, the interval between center axes of the input rotating arm shaft and the output rotating shaft is r, the two linear servo cylinders are arranged in an inner cavity of the rotation mechanism shell, the two linear servo cylinders are fixedly connected through a first connecting base, the output end of one linear servo cylinder controls transverse motion, and the transverse axis of the right-angle coordinate system is formed; and the output end of the other linear servo cylinder controls the longitudinal motion, and the longitudinal axis of the right-angle coordinate system is formed.

Description

technical field [0001] The invention relates to the technical field of servo cylinders, in particular to a vector rotary mechanism with servo cylinders. Background technique [0002] At present, there are two types of servo cylinders that can realize the rotary motion of the load: [0003] 1) Piston type swing servo cylinders (including rack and pinion type, screw piston type, chain type, crank type and reciprocating type) all use mechanical structures to realize the rotational movement of the load. However, the inherent friction, dead zone, and life of the mechanical structure itself greatly affect its use. [0004] 2) The vane type swing servo cylinder can realize the rotational movement of the load without any speed change mechanism. However, the sealing of moving parts is difficult, the processing is complicated, and the price is expensive. Contents of the invention [0005] In view of the above problems, the present invention provides a vector rotary mechanism with...
