A connecting rod 11 is fixedly installed on the middle part of the outer side of the two threaded movable sleeves 10. A bar slide 12 is symmetrically opened on the side of the bar shell 7 away from the rotating motor 5, and two connecting rods 11 are respectively slidably installed in the inside of the two bar slides 12. A movable connecting column 13 is fixedly installed on the end of the connecting rod 11 away from the threaded movable sleeve 10, and the two movable connecting columns 13 are movably contacted at the ends close to each other. An arc groove 14 is opened at the ends close to each other, and the two movable connecting columns 13 are away from one side of the bar shell 7 Both are fixedly installed with clamping blocks 15, and the ends of the two clamping blocks 15 close to each other are provided with clamping grooves 16.

[0023] Working principle: during operation, first use the fixing bolts that match the diameter of the fixed mounting hole 2 to fix the circular mounting seat 1, and then start the adjusting motor 8 to drive the bidirectional screw 9 to rotate, and the bidirectional screw 9 drives the threaded movable sleeve 10 to move, and the two threaded movable sleeves 10 move and disengage from the two limit rings 19 respectively.

The two clamping blocks 15 are reset and moved to clamp the chain link inside the two clamping grooves 16, and then the adjusting motor 8 is turned off and the electric telescopic rod 17 is started at the same time to push the positioning column 18 to reset and move. The positioning column 18 moves to contact with the chain link and squeezes the chain link to be positioned inside the two clamping grooves 16, and then the rotating motor 5, the mechanical arm 4 and the rotating motor 3 are restarted to drive the clamped chain link to move. After moving to the required position, the electric telescopic rod 17 is started again to drive the positioning column 18 to disengage from the chain link, and the adjusting motor 8 is started at the same time to open the two clamping blocks 15, release the clamping of the chain link, and the chain link can be put down. In this way, the automatic clamping robot for chain link bending forming processing can be used to facilitate more stable clamping of the chain link, ensure normal processing operation, and thus achieve better practicality.
