Abstract
A replaceable cylinder nut is characterized in that a thread hole is arranged on a cylinder pin. The cylinder nut structure is good in safety, suitable for connection of bolts of crucial positions, capable of effectively avoiding wreckage of a main structure caused by damage of threads, greatly prolonging service life of the main structure and reducing life period cost of the products.
Description
Technical field
The utility model belongs to the high-speed railway passenger technology, relates to the linkage structure between truck components and the bogie main structure, is applied on the CRH5 type EMU CA250 bogie.
Background technique
Traditional truck components is connected directly tapping on the framework main structure, the technology that bolt directly is screwed into of adopting with bogie main structure (for example framework, bolster).Adopt this kind technology, main structure screw buckles such as framework are damaged in car inspection and repair or unloading process easily, can only in case misoperation will cause scrapping of whole main structure, cause very big waste by repair welding or the reaming method solution of tapping again.
The model utility purpose
Technical problem to be solved in the utility model provides a kind of interchangeable cylindrical thread structure, inserts main structural components, plays the effect in tapping thread hole on the traditional sense, thereby avoids main structure owing to thread damage is scrapped.
For solving the problems of the technologies described above, the utility model provides a kind of replaceable cylindrical nut, it is characterized in that: open a tapped hole on straight pin.
The cylindrical nut safety of structure is very high, adapts to the key position bolt and connects, and this structure can effectively be avoided can improving the working life of main structure greatly because thread damage causes scrapping of main structure, reduces product life cycle cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the utility model user mode figure.
Embodiment
With reference to Fig. 1, Fig. 2, on straight pin 1, open a tapped hole 2.During use, open on main structural components 3 that two center lines intersect, the vertical circular hole of direction, wherein circular hole 4 diameters of original thread hole site are less, perpendicular circular hole 5 diameters are bigger, insert cylindrical nut 6 for 5 li at bigger circular hole, bolt is gone in the cylindrical nut by the circular hole fine jade than minor diameter, finishes being connected of associated components and framework main structure.
