Description

Technical Field

[0001] The utility model relates to the technical field of steel collar installation, in particular to an installation and fixing device suitable for multiple types of steel collars. Background Art

[0002] The steel ring is one of the key components in the spinning frame and plays a vital role in the spinning production process. Its main function is to provide a stable running track for the yarn and control the tension and twist of the yarn. The steel ring of the spinning frame usually has high precision and surface quality to reduce the friction and resistance of the yarn during operation. For twisting of fine yarn, a smaller diameter and more precise steel ring may be required, while for twisting of coarse yarn, a larger diameter and stronger steel ring may be required. The steel ring needs to be installed, fixed and calibrated when in use;

[0003] The utility model with application number 202221765537.3 discloses an installation mechanism for the steel collar of a ring spinning machine. By rotating a push handle, the push handle drives a disc to rotate, and a support rod slides on the disc through a sliding block. The disc drives a rotating plate to rotate, and the rotating plate drives a supporting assembly to rotate. The supporting assembly drives a clamping seat to clamp the steel collar. When disassembling, the operation is reversed, so that installation and disassembly are convenient. By placing the spindle into the positioning ring, the straightening mechanism can straighten the position of the spindle through a hinge, so that the steel collar and the spindle are in coaxiality, so as to prevent the position of the spindle and the steel collar from being offset during the installation process, which affects the subsequent work.

[0004] However, the above-mentioned installation mechanism of the ring spinning steel ring is not compatible with the installation of steel rings of different models, which makes the device less applicable. The above-mentioned installation mechanism of the ring spinning steel ring needs to be re-calibrated for coaxiality after the steel ring is replaced, which easily affects the installation efficiency. Therefore, the utility model proposes a device for installing and fixing multiple types of steel rings to solve the problems existing in the prior art. Utility Model Content

The arc-shaped rubber block clamps and fixes the steel collars of various models, effectively improving the applicability of the device to various models of steel collars and solving the problem of inability to install steel collars of different models compatibly. The turntable rotates and the limit slider slides along the annular slide groove at the same time, so that the turntable remains stably rotated below the fixed plate to prevent displacement from affecting the coaxiality after installation and fixation.
