Description

Technical Field

[0001] The utility model relates to the technical field of spherical flange connection devices, in particular to a spherical flange connection structure. Background Art

[0002] Flange is a part that connects shafts to each other and is used to connect pipe ends. It is also used as a flange on the inlet and outlet of equipment to connect two devices, such as reducer flange. Flange connection or flange joint refers to a detachable connection in which flange, gasket and bolts are connected to each other as a combined sealing structure. Spherical flange is one type of flange.

[0003] Linear guides are used in high-precision or high-speed linear reciprocating motion. The function of linear guides is to support and guide moving parts to make reciprocating linear motion in a given direction. Sliders are commonly installed on linear guides. The spherical flange is fixed to the slide at the upper end of the guide through a connecting structure, while the existing connecting structure is directly fixed to the slide at the upper end of the guide through bolts and nuts. After the slide at the upper end of the guide moves for a long time, the vibration generated during the operation of the equipment can easily cause the nut to loosen, causing the connecting structure and the slide at the upper end of the guide to loosen, affecting the equipment processing. Utility Model Content

[0004] To this end, an embodiment of the utility model provides a spherical flange connection structure to solve the problem in the prior art that vibrations generated during operation of the equipment easily lead to loosening of the nut.
