Rod body connecting mechanism

Abstract

The invention belongs to rod body connection design technologies and relates to a method for designing a rod body connecting mechanism with a positioning device. The rod body connecting mechanism is composed of a cantilever connecting rod (1), an upper joint (2), a rivet (3), a lower joint (4), a sleeve (5) and a connecting piece (6). The connecting piece (6) at one end of the rod body is firmly fixed by an operator, the connecting direction of the cantilever connecting rod (1) at the other end of the rod body can be controlled to be invariable, and due to matched connection between the upper joint (2) and the lower joint (4), the sleeve (5) is rotated to realize reliable positioning of the cantilever connecting rod (1), and the condition that the cantilever connecting rod (1) is loosened under the action of external force can be avoided. In addition, the rod body is totally connected by a fastener, high-temperature welded connection in the prior art is avoided, the difficulty of the manufacturing process is reduced, the precision is high, and the coaxiality between the rod body and the joint is high.

Description

technical field [0001] The invention relates to a rod connecting mechanism technology, in particular to a rod connecting mechanism technology with a positioning device. Background technique [0002] A rod body connection mechanism, which is widely used in the connection of various mechanical rod parts, especially when one end of the rod body is a cantilever rod, and when the rod body needs to be reliably positioned when connecting the rod body, the rod body connection mechanism plays an important role. [0003] The rod body connection mechanism in the prior art is mainly composed of a joint, a nut and a cantilever rod. Wherein, the cantilever rod body is a hollow structure, and its two ends are welded with joints. Through the rotational movement of the nut, the connection of the cantilever rod can be realized. [0004] However, in the prior art, the cantilever rods are connected by bolts. When screwed, the cantilever rods are prone to loosening under the action of external...

AI Technical Summary

Problems solved by technology

[0004] However, in the prior art, the cantilever rods are connected by bolts. When screwed, the cantilever rods are prone to loosening under the action of external force. In addition, the joints at both ends and the cantilever rod body are connected by welding. Due to the high process requirements during welding, Difficult to control tolerances and less precision due to high temperature soldering that tends to affect concentricity

In addition, the rod body is connected by screw connection. When the screw connection is performed, the position of the connection hole in the joint changes and cannot be connected.
