Description

Technical Field

[0001] The invention relates to the technical field of transmission parts, and in particular to a floating joint anti-loosening method and anti-loosening structure. Background Art

[0002] Cylinders are a common power source in various types of processing machine tools. They are generally used to drive other components to perform linear reciprocating motion. Among them, the drive of some fixtures is achieved by cylinders. The cylinder pushes the fixture to clamp the workpiece to be clamped, and then processes the workpiece. In order to ensure the accuracy of clamping and positioning, the fixture is generally restricted in its range of motion and is only allowed to reciprocate in a single direction.

[0003] Existing cylinders and floating joints are often connected by threads. When the equipment is in motion for a long time, the cylinder rod will rotate during the back-and-forth motion, which will cause the number of connecting threads between the floating joint and the cylinder rod to become fewer and fewer. The floating joint and the cylinder rod will become loose, causing the cylinder rod to fall off, resulting in equipment downtime. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a floating joint anti-loosening method and anti-loosening structure to prevent the actuator rod and the floating joint from loosening, and the disassembly and assembly are simple, time-saving and labor-saving.
