Abstract

The invention discloses a threaded connection type robot joint connection assembly based on middle pieces. The threaded connection type robot joint connection assembly based on the middle pieces mainly comprises thread connection rings and the middle pieces. The robot joints comprise a first joint body and a second joint body. The threaded connection rings comprise two identical threaded connection ring bodies. The middle pieces comprise a first middle piece body and a second middle piece body. The middle pieces are provided with outer ring inclined planes to be matched with inner ring inclined planes of the threaded connecting rings. After the threaded connecting rings are matched with the middle pieces, the first middle piece body and the second middle piece body are matched with pin holes formed in the middle pieces through two pins to realize circumferential positioning and are assembled together through bolts to form a connecting assembly. During assembly, external threads arranged at the tail end of the joints are connected with internal threads of the threaded connection rings, and the installation is completed after the required pre-tightening force is generated between thethreaded connection rings and the threads. During disassembly, the threaded connection rings are screwed out until the joints can be removed to complete the disassembly; and therefore, the threaded connection type robot joint connection assembly based on the middle pieces can realize quick and convenient disassembly and assembly between different robot joint modules.

Description

Technical field [0001] The invention relates to the field of robots, in particular to a robot joint connection assembly based on a middleware thread connection type. Background technique [0002] In the prior art, the connection between the robot joint and the joint is usually a circumferential fixed connection using bolts. This requires connecting flanges at the robot joints. However, the presence of flanges will seriously affect the appearance of the robot; the other way is to set the connecting flanges inside the robot joints, but this will make the bolts tighten. Very inconvenient. [0003] In this connection method with evenly distributed bolts, more bolts are usually used to ensure the strength of the connection. Therefore, the pre-tightening force of each bolt needs to be considered during installation, and multiple bolts must be disassembled during disassembly, which takes a lot of time during disassembly and assembly. [0004] It can be seen that the existing robot joint ...
