Problems solved by technology

[0004] The present invention designs a rack-and-pinion locking device for a mechanical arm. The technical problem it solves is that the clamp plate locking device used on the existing mechanical arm has a complex structure, a large volume, and high manufacturing costs and maintenance costs. Higher cost, inconvenient to repair defects

Embodiment Construction

[0024] Combine below figure 1 , the present invention is further described:

[0025] A rack-and-pinion locking device for a mechanical arm, comprising a plurality of joint arms, including at least a first joint arm 2 and a second joint arm 8, the second joint arm 8 can swing relative to the first joint arm 2 or Rotation, wherein a rack-and-pinion locking device is provided between the first joint arm 2 and the second joint arm 8 .

[0026] The rack-and-pinion locking device includes a gear 7 and a rack 6, the gear 7 and the rack 6 are meshed and matched with each other, the gear 7 is installed on the second section arm 8, and the rack 6 is separated from the gear 7 or The snapping realizes the separation of the first section arm 2 and the second section arm 8 .

[0027] One end of the lever 5 is connected to the rack 6 , the other end of the lever 5 is connected to the cylinder 3 , and the fulcrum of the lever 5 is installed on the first joint arm 2 .

[0028] The fulcrum i...

Abstract

The invention relates to a gear rack type locking device used for a mechanical arm, which comprises a plurality of node arms, wherein one gear rack type locking device is arranged between two adjacent node arms. The invention designs the gear rack type locking device. When the mechanical arm is not used, the node arms can be prevented from relatively rotating or moving, and therefore the phenomenon that personnel or objects are damaged because the node arms rotate or swing can be avoided.

Description

technical field [0001] The invention relates to a mechanical locking device, in particular to a rack-and-pinion locking device for a mechanical arm. Background technique [0002] At present, with the rapid development of the economy and the improvement of people's living standards, automobiles have gradually entered every family and become a means of transportation. The automotive equipment industry is also constantly developing, and is committed to continuously reducing the labor intensity of workers. Therefore, power-assisted robotic arms are widely used in automotive production lines, and their cost-maintenance and safety are also increasingly valued. The robotic arm has a high degree of freedom just like the human arm, so it is hoped that one or several degrees of freedom can be well controlled when it is not working, so as not to accidentally injure people and objects (such as the body), causing safety accidents and accidents. necessary damage. [0003] At present, th...
