[0023] like Figures 1 to 3 As shown, a spindle fixing device for a ring spinning machine comprises a fixing seat 1 and a spindle body 7, the surface of the fixing seat 1 is threadedly connected with a bolt 2, a horizontal plate 3 is arranged directly above the fixing seat 1, and a stabilizing mechanism 4 for reducing the amplitude of the spindle body 7 is arranged on the opposite surfaces of the top of the fixing seat 1 and the bottom of the horizontal plate 3, a fixing mechanism 5 for limiting and fixing spindle bodies 7 of various specifications is arranged on the top and bottom of the horizontal plate 3, and a locking mechanism 6 for locking the fixing mechanism 5 is arranged at the bottom of the horizontal plate 3; specifically, through the bolt 2 The entire device can be fixed on the surface of the ring spinning machine, and the spindle bodies 7 of various specifications can be limited and fixed by the fixing mechanism 5. It has a wide range of applications and is convenient for disassembling and assembling the spindle body 7. After the fixing mechanism 5 limits the spindle body 7, the fixing mechanism 5 is locked by the locking mechanism 6, thereby improving the fixing effect of the fixing mechanism 5 on the spindle body 7. The stabilizing mechanism 4 can reduce the shaking phenomenon of the spindle rod and spindle disk of the spindle body 7 during rotation, thereby reducing the amplitude of the spindle body 7, and then improving the winding quality of the yarn.
