Mechanical arm suitable for grabbing components with multiple specifications

Abstract

The invention discloses a mechanical arm suitable for grabbing components with multiple specifications. The mechanical arm comprises a first mechanical arm, wherein a base is movably mounted at the lower end of the first mechanical arm; through cooperative application of a first joint block, a second joint block and third joint blocks, the components with various different specifications can be conveniently and rapidly grabbed and transmitted; through cooperative application of a second outer rotary shaft, the third joint blocks and a buffering pad, the second outer rotary shaft is rotated toenable a plurality of third joint blocks to wrap and clamp from the bottoms of the components so as to realize the purpose of rapidly grabbing the components; through cooperative application of a first outer rotary shaft, a first fixture block and a second fixture block, the rotary efficiency and stability of the second joint block can be effectively improved; and through clamping fixation of thefirst fixture block and the second fixture block, the stability that the second joint block grabs the component can be effectively improved to avoid the situation that the component shakes during thetransportation process due to loosening of the second joint block.

Description

technical field [0001] The invention relates to the technical field of crop processing, in particular to a mechanical arm suitable for grabbing parts of various specifications. Background technique [0002] The robotic arm is the most widely used automatic mechanical device in the field of robotic technology. It can be seen in industrial manufacturing, medical treatment, entertainment services, military, semiconductor manufacturing, and space exploration. The structure of the arm should be compact Only small size can make the arm movement light and flexible. Installing rolling bearings or ball guide rails on the movement arm can also make the arm movement light and stable. [0003] The publication number (CN204397909U) discloses a mechanical arm auxiliary device and a mechanical arm system. The mechanical arm moves horizontally or vertically through the machine control terminal. The first detection device of the upward motion state, the second detection device for detecting...

AI Technical Summary

Problems solved by technology

[0005] (1) Through the cooperative use of the first joint block, the second joint block and the third joint block provided, the present invention can conveniently and quickly grab and transfer parts of various specifications, and expand the grasping capacity of the gripper. The picking function effectively improves the use efficiency of the gripper. By simultaneously stretching and contracting the first joint block, the second joint block and the third joint block, the parts can be wrapped and fixed, and the stability during the transfer of parts can be improved. It is suitable for grabbing parts of different specifications, and solves the problem of low efficiency of parts grabbing caused by only grabbing parts of a single specification in the existing solutions;
