A positive and negative thread quick connecting mechanism for a robot joint comprises a first connecting flange and a second connecting flange, wherein a first end tooth is arranged on the first connecting flange, positive threads are arranged on the outer wall of the first connecting flange, a second end tooth matched with the first end tooth is arranged on the second connecting flange, and negative threads are arranged on the outer wall of the second connecting flange;
And a positive and negative threaded nut which is correspondingly matched and connected with the positive thread and the negative thread is arranged between the first connecting flange and the second connecting flange, and a fastening screw and a handle are arranged on the positive and negative threaded nut.
furthermore, a first positioning mark and a second positioning mark for circumferential positioning during installation are correspondingly arranged on the first connecting flange and the second connecting flange.
Furthermore, the positive and negative threaded nuts are provided with openings, and the phase positions of the openings are provided with force unloading grooves.
Furthermore, a countersunk hole and a first threaded hole for mounting a fastening screw are respectively formed in two ends of the opening.
Furthermore, the outer side wall of the positive and negative thread nut is provided with a second threaded hole for mounting a handle, and the positive and negative thread nut has the advantages that:
Compared with the prior art, the invention adopts the modes of end tooth matching and thread fastening, thereby greatly improving the installation efficiency of the robot joint; the end teeth are adopted to transmit torque, so that the strength is high, and the end teeth can be applied to occasions with large torsional force; the outer wall of the positive and negative thread nut is provided with a threaded hole which is matched with the handle, so that the joint is very easy to disassemble; the opening structure is arranged, and the thread connection strength can be higher by matching with the fastening screw; in addition, the corresponding matching position of the first connecting flange and the second connecting flange is provided with a positioning mark which can prevent installation dislocation.
