Description

Stable guiding device for telescopic rod of air cylinder Technical Field The utility model relates to the technical field of cylinder telescopic rod auxiliary devices, in particular to a cylinder telescopic rod stable guide device. Background Along with the discovery of technology, various automatic or semi-automatic devices are all independent of the cylinder, the purpose of automatic production of some products is accomplished with the help of the cylinder, can install the guide bar additional in the both sides of cylinder telescopic link and cooperate the use, thereby promote the production efficiency of product, but under high-speed flexible or overlength stroke operating mode, the cylinder telescopic link easily receives horizontal offset force and inertial impact, lead to the motion orbit skew, the wearing and tearing of sealing member acceleration, even initiate clamping stagnation or fracture, and produced horizontal offset force and inertial impact can be conducted to the guide bar, and the force that the metalwork that connects in the guide bar bottom bore comes from a plurality of directions, cause the metalwork of guide bar and bottom to take place slight deformation along the junction.
