A self-driving robot shifting manipulator

Abstract

An automatic driving robot gear shifting manipulator, comprising a first stepping motor, a first slider, a first slide rail, a first connecting rod, a second connecting rod, a first swing rod, a gripper, a second stepping motor, The second slider, the second slide rail, the third connecting rod, and the fourth connecting rod; the first stepping motor, the second stepping motor, the first sliding rail, and the second sliding rail are all fixed on the upper end of the box; the first The stepping motor drives the first slider to move back and forth along the first slide rail; the third connecting rod cooperates with the chute in the first slider and is perpendicular to the sliding direction of the first slider; the lower end of the second connecting rod is connected to the third connecting rod. The upper end of the second connecting rod is connected with the rear end of the first swing rod through a pin shaft; the front end of the first swing rod is connected with the gripper; the second stepper motor drives the second slider to slide along the second slide rail, and the sliding direction perpendicular to the first slider; the third connecting rod is connected with the second slider; the lower end of the fourth connecting rod is connected with the third connecting rod; the upper end of the fourth connecting rod is connected with the first swing rod through a pin shaft; Type of cab and gear shifting.

Description

technical field [0001] The invention belongs to the technical field of driving devices, in particular to a shift manipulator of an automatic driving robot. Background technique [0002] In recent years, more and more people have realized the advantages of unmanned robots and gradually began to study them. Among them, the shifting manipulator of unmanned robots is also our main breakthrough. On the one hand, the shift manipulator of the self-driving robot can accurately complete the shifting action of the vehicle alone, and through computer control, it can cooperate with the mechanical legs to complete the switching between starting and shifting actions. On the other hand, the shifting manipulator of the autonomous driving robot needs to be conveniently controlled, not only to realize the shifting of the car, but also to realize the shifting of other crane cabs, so as to improve the applicability of the unmanned robot.

Problems solved by technology

[0003] Chinese patent CN201110359937.4 discloses a shifting manipulator realized in a pneumatic structure. The shifting manipulator realizes the shifting action by adding multiple cylinders. However, because the drive requires an air source and the cost of compressed gas is high, at the same time the gas The controllability is weak, not only the control is not precise, but also increases the weight of the mechanism

In addition, the shift manipulator has a complex structure and a large volume, so it cannot be installed in the cab of a car without damage.

[0004] Chinese patent CN2015101881.6 discloses a gearshift manipulator and its control on an automobile synchronizer test bench. The gear selection process of the gearshift manipulator is controlled by a motor, and the gearshift process is controlled by a cylinder, but the cylinder is heavy and unstable during operation. , making the shifting operation inaccurate; in addition, its structure is too complex, and it is easily affected by external factors in the control process, resulting in large deviations in operation
