Detailed Description

The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

Referring to fig. 1-3, a robot end anti-collision device in this embodiment includes a base 1, a connection structure is disposed on the base 1, and the base 1 is connected with a first connection disc 6 through the connection structure.

Embodiment one: the connecting structure in this embodiment includes fixed mount 2 of fixed mounting in the outside of base 1, rotates on the mount 2 and installs thread bush 3, and thread bush 3 is located the outside one end of mount 2 and extends towards the outside and set up the recess at the surface, can be convenient for rotate thread bush 3.

The screw sleeve 3 is connected with a screw 4 through threads, the outside of the screw 4 is fixedly provided with a protection cylinder 5, the first connecting disc 6 is fixedly arranged outside the protection cylinder 5, one end of the protection cylinder 5 is also connected with a second connecting disc 10, the second connecting disc 10 is fixedly provided with a micro switch 13 for transmitting collision signals to the robot, and a spring 12 is arranged between the second connecting disc 10 and the protection cylinder 5.

The locating pin 7 is fixedly installed on the first connecting disc 6 in the embodiment, the pin groove 11 is formed in the second connecting disc 10, the cross sections of the locating pin 7 and the pin groove 11 are V-shaped, and the relative connection of the first connecting disc 6 and the second connecting disc 10 can be conveniently located through the arrangement of the locating pin 7 and the pin groove 11.
