Description

Technical Field

[0001] The utility model belongs to the support structure of a ring spinning frame, and particularly relates to a dragon tendon of a spinning frame with high stability and easy processing. Background Art

[0002] At present, dragon tendons are generally arranged on ultra-long spinning frames, and spindles are installed on the upper surface of the dragon tendons. However, since the outer surface and the upper and lower side surfaces of the dragon tendon need to be milled flat into a plane, and then mounting holes are penetrated through the surface of the dragon tendon, the processing of the dragon tendon is time-consuming. Moreover, due to the large processing amount of the dragon tendon, the tool wears greatly during the processing, resulting in a reduction in processing efficiency and an increase in processing cost; in addition, since all surfaces of the dragon tendon need to be integrally processed, the natural characteristics and surface structure of the dragon tendon will be damaged, and the cutting stress and residual stress generated during the cutting of the dragon tendon have a great influence on the straightness and flatness of the entire dragon tendon; at the same time, due to drilling holes on the surface of the dragon tendon, its bearing capacity becomes poor, reducing the service life of the dragon tendon. Affected by the self-gravity of the dragon tendon and the spindles installed on it, the dragon tendon of the spinning frame is prone to bending. Once the dragon tendon of the spinning frame bends, the positions of the spindles installed on the dragon tendon of the spinning frame will change, thereby affecting the normal operation of the spinning frame.
